Abstract: The potential of multilayered cellulose nanocrystals (CNCs)/gibbsite nanoplatelets (GNPs) thin films to be built onto various substrates of interest for packaging applications using the layer-by-layer assembly and to improve their oxygen barrier properties has been explored. First, the use of complementary structural characterization techniques, namely AFM, ellipsometry and spectral reflectance, evidenced that when deposited onto model silicon substrates the all-nanoparticles hybrid films were homogenous, of very reduced porosity, and exhibited a thickness linearly increasing with the number of deposited layers, which is fully compatible with the alternating deposition of monolayers of GNPs and of CNCs. Secondly, scanning electron microscopy observations showed the successful deposition of such homogeneous and dense hybrid thin films onto various types of flexible substrates such as cardboard, blotting paper, smart paper, polyethylene (PE) films, PE-coated cardboard, which display very different chemical compositions, hydrophilicities, and surface morphologies. These results show the remarkable robustness of the deposition and building process, which is likely due to the versatility of the LbL assembly technique and to the strong electrostatic and hydrogen bonding interactions between the two types of colloids. The measurement of the oxygen transmission rate at 23°C and 50% RH showed that the oxygen barrier properties of the bare substrates could be significantly improved (e.g. 75% decrease of the OTR) after the deposition of such thin (

Abstract: Recently, paper has been mentioned in many research studies [1-4] as a good choice of a substrate material for flexible electronics. In this paper, the E4D paper has been characterized by the cavity perturbation method, then a monopole antenna structure, called “Sapin” by its shape, has been designed on it to cover a very wide frequency range including two WLAN bands. The proposed antenna is rather compact with the dimensions of 45 × 28 mm2 with good matching characteristics. The simulated return loss is over 35 dB at 2.45 GHz, over 20 dB at 5.5 GHz. Especially, this antenna has quite large bandwidth, from 2.2 GHz to over 10 GHz and nearly omnidirectional radiation patterns at 2.45 GHz while a little more directive at 5.5 GHz. Six prototypes have been fabricated on 104-μm-thick E4D paper by screen printing technology in order to verify the stability of measurement results. They are thin and flexible that can be attached to a box with various shapes. The simulation and measurement results, which showed rather good agreement, confirmed a good performance of the designed antenna.

Abstract: International audience; Microbial anodes were formed under polarization at −0.3 V/SCE on graphite plates in effluents from a pulp and paper mill. The bioanodes formed with the addition of acetate led to the highest current densities (up to 6 A/m2) but were then unable to oxidize the raw effluent efficiently (0.5 A/m2). In contrast, the bioanodes formed without acetate addition were fully able to oxidize the organic matter contained in the effluent, giving up to 4.5 A/m2 in continuous mode. Bacterial communities showed less bacterial diversity for the acetate-fed bioanodes compared to those formed in raw effluents. Deltaproteobacteria were the most abundant taxonomic group, with a high diversity for bioanodes formed without acetate addition but with almost 100% Desulfuromonas for the acetate-fed bioanodes. The addition of acetate to form the microbial anodes induced microbial selection, which was detrimental to the treatment of the raw effluent.

Abstract: International audience; Microbial bioanodes were formed in pulp and paper effluent on graphite plate electrodes under constant polarization at -0.3 V/SCE, without any addition of nutriment or substrate. The bioanodes were characterized in 3-electrode set-ups, in continuous mode, with hydraulic retention times from 6 to 48 h and inlet COD from 500 to 5200 mg/L. Current densities around 4 A/m2 were obtained and voltammetry curves indicated that 6 A/m2 could be reached at +0.1 V/SCE. A theoretical model was designed, which allowed the effects of HRT and COD to be distinguished in the complex experimental data obtained with concomitant variations of the two parameters. COD removal due to the electrochemical process was proportional to the hydraulic retention time and obeyed a Michaelis-Menten law with respect to the COD of the outlet flow, with a Michaelis constant KCOD of 400 mg/L. An inhibition effect occurred above inlet COD of around 3000 mg/L.

Abstract: International audience; A Kraft pulp mill effluent was used as the inoculum to form microbial bioanodes under controlled potential at +0.4 V/SCE. Samples were collected at the inlet and outlet of the aerated lagoon of the treatment line. The outlet sample allowed efficient bioanodes to be designed (5.1 A/m²), which included Geobacter and Desulfuromonas sp. in their microbial community. In contrast, the bioanodes formed with the inlet sample did not contain directly connecting anode-respiring bacteria and led to lower currents. It was necessary to reform this bioanode at lower applied potential (-0.2 V/SCE) to select more efficient electroactive species and increase the current density to 5 A/m².

Abstract: International audience; Today’s environmental concerns are pressuring industries to substitute paper-based materials in place of plastics in many sectors including packaging. However, assembling papers and paperboards using environmentally friendly solutions remains a technological challenge. In this context, ultrasonic (US) welding is an alternative to adhesives. In this work, the potential of US welding to assemble folding boxboards was investigated. Folding boxboards are commonly coated to enhance printability. This coating is generally composed of mineral pigments (85 to 90%) and polymer binders (10 to 12%). This study evaluated whether the presence of the coating layer allows the assembly of paperboards by US welding. Results indicated that welding coated folding boxboards is possible provided that coating weight and binder content are high enough. The mechanical performances of the welded boards met the requirements of most packaging applications. Adhesion in the welded joint resulted from a combination of thermoplastic (melting and flowing of the binder) and thermoset (degradation reactions) effects. However, it was not possible to assemble coated folding boxboards without degrading the welding zone. While the materials and process need to be optimized, this work represents a big step forward toward the adhesive-free assembling of paper-based materials.

Abstract: International audience; Microbial anodes were formed under polarisation at -0.2 V/SCE on smooth graphite plate electrodes with paper mill effluents. Primary, secondary and tertiary biofilms were formed by a successive scratching and re-inoculation procedure. The secondary and tertiary biofilms formed while decreasing the polarisation potential allowed the anodes to provide current density of 6 A/m² at -0.4 V/SCE. In contrast, applying -0.4 V/SCE initially to form the primary biofilms did not lead to the production of current. Consequently, the scratching/re-inoculation procedure combined with progressive lowering of the applied potential revealed an efficient new procedure that gave efficient microbial anodes able to work at low potential. The observed progressive pH drift to alkaline values above 9 explained the open circuit potentials as low as -0.6 V/SCE. The remarkable performance of the electrode at alkaline pH was attributed to the presence of Desulfuromonas acetexigens as the single dominant species in the tertiary microbial anodes.

Abstract: International audience; This paper introduces the first chipless tag in the mmWave band based on resonating elements. One goal is to introduce a millimeter-wave communication system based on chipless tags without a ground plane based on traditional low-cost printing methods. For this purpose, millimeter-wave chipless resonant tags have been designed considering the trade-offs such as RCS signal level, losses, and design constraints. The proposed design is based on single-layer printing, where each resonating element is replicated to satisfy constraints related to the chipless reading process at these frequencies. As a result, a reading range up to $20~\si{cm}$ has been noticed in an office environment.

Abstract: International audience; Three complementary Kraft lignins and a Soda lignin were characterized by NMR (31P, 13C, and HSQC) and GPC. Their theoretical yield in monomers (TMY) assuming a complete cleavage of all β-O-4 linkages was calculated based on these analyses. The most recalcitrant Kraft lignin according to the TMY criteria was depolymerized in supercritical ethanol (250 °C, H2, 110 bar) with Pt/C, Ni/C, and Ru/C catalysts. All catalysts present an important effect on monomers (analyzed by GC/MS), oligomers (by UV fluorescence), and char yields. They promote cracking reactions and the stabilization of the broken bonds by H-transfers. The hydrogenation of the side chains of the monomers is also promoted to notably produce propyl-guaiacol. We show that an oligomeric pool prevails for all catalysts. Then, the effect of lignin structure on the depolymerization mechanism was studied by comparing the 4 lignins with the least precious catalyst (Ni/C). The S/G ratio of monomers is well related to the S/G ratio of lignins. Under our conditions, the β-O-4 content and the TMY do not control the yields in monomers. They are not relevant indicators for the depolymerization of these recalcitrant technical lignins. Future work should focus on novel catalysts and processes to improve the selective conversion of C–C bonds if monomers remain the targeted product.

Abstract: International audience; Ultrasonic welding is a serious candidate in the development of methods to assemble papers and paperboards without using additional substances. However, the ultrasonic welding of papers remains a technological challenge considering the low weldability of lignocellulosic materials. This study aims to investigate on the ultrasonic welding process applied to papers in order to identify the processing conditions which favor the formation of strong welded joints. To reach such purpose, an experimental strategy was developed by combining the characterization of welded materials and the monitoring of process parameters. Experimentations were performed using a reference paper displaying a good weldability to specifically highlight the contribution of process parameters. Results indicate that the process is highly sensitive to vibration amplitude, power supplied by the high frequency generator, and sample thickness. Power seems to be a reliable indicator of the severity of the process. A strong decrease in the strength of the welded joints is observed when working with low thicknesses. It seems that the layers coated on top of papers are the main part of the material contributing in the development of adhesion at the welding joint. Overall, instrumenting the device has led to a better understanding of the ultrasonic welding of papers.

Abstract: Cellulose nanofibrils (CNF) are renewable bio-based materials with high specific area, which makes them ideal candidates for multiple emerging applications including for instance on-demand drug release. However, in-depth chemical and structural characterization of the CNF surface chemistry is still an open challenge, especially for low weight percentage of functionalization. This currently prevents the development of efficient, cost-effective and reproducible green synthetic routes and thus the widespread development of targeted and responsive drug-delivery CNF carriers. We show in this work how we use dynamic nuclear polarization (DNP) to overcome the sensitivity limitation of conventional solid-state NMR and gain insight into the surface chemistry of drug-functionalized TEMPO-oxidized cellulose nanofibrils. The DNP enhanced-NMR data can report unambiguously on the presence of trace amounts of TEMPO moieties and depolymerized cellulosic units in the starting material, as well as coupling agents on the CNFs surface (used in the heterogeneous reaction). This enables a precise estimation of the drug loading while differentiating adsorption from covalent bonding (∼1 wt% in our case) as opposed to other analytical techniques such as elemental analysis and conductometric titration that can neither detect the presence of coupling agents, nor differentiate unambiguously between adsorption and grafting. The approach, which does not rely on the use of 13C/15N enriched compounds, will be key to further develop efficient surface chemistry routes and has direct implication for the development of drug delivery applications both in terms of safety and dosage., DNP-enhanced solid-state NMR unravels the surface chemistry of functionalized nanocellulose.

Abstract: Several low-density crumpled paper-based materials were fabricated by varying both the volume fraction and the geometry and mechanical properties of paper sheets. Their 3D architecture was investigated using X-ray microtomography. Microstructure descriptors such as the pore size distribution, the mean curvature distribution and the volume fraction of ordered domains were finely analyzed. Their mechanical properties were also assessed using uniaxial compression tests. Our results showed that crumpled materials exhibited a particular porous microstructure with a reproducible mechanical behavior between foams and entangled fibrous materials. Their compressive behavior was characterized by successive elastic, strain-hardening and densification regimes. The effects of the geometry, microstructure and mechanical properties of the sheets on the process-induced microstructures and mechanical performances were discussed. In particular, a simple micromechanical approach was used to estimate analytically and from the 3D images the role of ridges and ordered domains on the mechanical properties of crumpled papers. The evolution of their Young's moduli and yield stresses were studied as a function of their relative densities and compared with experimental data available in the literature for other cellular materials, showing that crumpled papers are promising renewable alternatives to standard polymer foams for several engineering applications, due to the proper combination of mechanical properties, porosity, cost, and easy fabrication.

Abstract: Cationization of cellulose fibers introduces positives charges and thus decreases the energy consumption to produce cellulose nanofibrils (CNF), improves their quality and confers them antimicrobial properties. In this study, cationic CNF at 17 wt% solid content were produced for the first time using an energy efficient process: the twin-screw extrusion (TSE). The production was compared to the production of enzymatic CNF using the same mechanical treatment and the efficiency of cationization was discussed. CNF produced were characterized using different techniques such as optical microscopy, atomic force microscopy, mechanical properties or transparency and finally classified using the quality index. Despite a slipping effect in the TSE which leads to intact residual fibers, highly transparent CNF with high Young’s modulus (10 GPa) and suitable quality index were obtained consuming only 1100 kW h/t. Activity of cationized CNF to limit bacteria proliferation has even been confirmed.

Abstract: International audience; In this work, we propose a THz tag structure based on a stack of different dielectric layers made of PE and PE-TiO2 mixture, in which we voluntary randomly deposit metallic flakes. Due to the randomness of the flake distribution (position and size), such a structure exhibits a potential unique THz signature that could be used to address identification using targeted statistical analysis. The signature is obtained by making a 2D THz image of a given area of the structure.

Abstract: International audience; Novel design of electrochromic devices (ECDs) known for their ability to modify optical properties under an applied voltage, based on a minimization of the number of layers is reported. The use of a metallic electrode, playing the role of both the conductive layer and the counter electrode, allows us to simplify the assembly of a commonly five-layer battery-type device to four-layer ECD. Further minimization of the number of layers is achieved using a conductive and electrochromic material. The novelty of the device configuration is illustrated using poly(3,4-ethylenedioxythiophene) (PEDOT)-based materials as EC layer, lithium-based ionic liquid as electrolyte, and Ag as counter electrode. Such a four- or three-layer ECD deposited on paper substrate switches from light to deep blue in a narrow 0.7 V voltage window. Preliminary investigations of the mechanism indicate traces of Ag on the PEDOT layer upon cycling. Finally, the printed ECD is successfully activated using a mobile phone.

Abstract: International audience; In order to lift the barrier of a poor interfacial interaction between cellulosic plant fibers and polymeric matrices in biocomposites, an eco-friendly surface modification of fibers was explored. A solvent-free gas-phase ester-ification applied to cellulose particles allowed to graft palmitoyl moieties on their surface in order to make them more compatible with non-polar polymers for composite applications. The efficiency of the treatment was evidenced from FT-IR analysis, and the degree of substitution (DS) was quantified by solid-state 13 C NMR spectroscopy. The effect of surface grafting on resulting intrinsic characteristics of cellulose particles, i.e. crys-tallinity, thermal stability, morphology, surface free energy and water vapor sorption were investigated respectively by X-ray diffraction, thermogravimetric analysis, SEM observations coupled with image analysis, contact angle measurements and dynamic vapor sorption system (DVS). It was shown that a DS as low as 0.01 was enough to drastically increase the hydrophobicity of cellulose particles without affecting the inner properties of cellulose.

Abstract: We report how the electron transport through a solid-state metal/Gly-Gly-His tripeptide (GGH) monolayer/metal junction and the metal/GGH work function are modified by the GGH complexation with Cu2+ ions. Conducting AFM is used to measure the current-voltage histograms. The work function is characterized by combining macroscopic Kelvin probe and Kelvin probe force microscopy at the nanoscale. We observe that the Cu2+ ions complexation with the GGH monolayer is highly dependent on the molecular surface density and results in opposite trends. In the case of a high density monolayer the conformational changes are hindered by the proximity of the neighboring peptides, hence forming an insulating layer in response to copper-complexation. Whereas the slightly lower density monolayers allow for the conformational change to a looped peptide wrapping the Cu-ion, which results in a more conductive monolayer. Copper-ion complexation to the high- and low-density monolayers systematically induces an increase of the work functions. Copper-ion complexation to the low-density monolayer induces an increase of electron transport efficiency, while the copper-ion complexation to the high-density monolayer results in a slight decrease of electron transport. Both of the observed trends are in agreement with first-principle calculations. Complexed copper to low density GGH-monolayer induces a new gap state slightly above the Au Fermi energy that is absent in the high density monolayer., Comment: Full paper with supporting information

Abstract: Background Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that cleave polysaccharides through an oxidative mechanism. These enzymes are major contributors to the recycling of carbon in nature and are currently used in the biorefinery industry. LPMOs are commonly used in synergy with cellulases to enhance biomass deconstruction. However, there are few examples of the use of monocomponent LPMOs as a tool for cellulose fibrillation. In this work, we took advantage of the LPMO action to facilitate disruption of wood cellulose fibers as a strategy to produce nanofibrillated cellulose (NFC). Results The fungal LPMO from AA9 family (PaLPMO9E) was used in this study as it displays high specificity toward cellulose and its recombinant production in bioreactor is easily upscalable. The treatment of birchwood fibers with PaLPMO9E resulted in the release of a mixture of C1-oxidized oligosaccharides without any apparent modification in fiber morphology and dimensions. The subsequent mechanical shearing disintegrated the LPMO-pretreated samples yielding nanoscale cellulose elements. Their gel-like aspect and nanometric dimensions demonstrated that LPMOs disrupt the cellulose structure and facilitate the production of NFC. Conclusions This study demonstrates the potential use of LPMOs as a pretreatment in the NFC production process. LPMOs weaken fiber cohesion and facilitate fiber disruption while maintaining the crystallinity of cellulose.

Abstract: We use a network of molecularly linked gold nanoparticles (NPSAN: nanoparticles self-assembled network) to demonstrate the electrical detection (conductance variation) of a plasmon-induced isomerization (PII) of azobenzene derivatives (azobenzene bithiophene : AzBT). We show that PII is more efficient in a 3D-like (cluster-NPSAN) than in a purely two-dimensional NPSAN (i.e., a monolayer of AzBT functionalized Au NPs). By comparison with usual optical (UV-visible light) isomerization of AzBT, the PII shows a faster (a factor about 10) isomerization kinetics. Possible PII mechanisms are discussed: electric field-induced isomerization, two-phonon process, plasmon-induced resonant energy transfer (PIRET), the latter being the most likely., Final manuscript with supporting information

Abstract: International audience; In the present work, electrically conductive and mechanically resistant carbon structures were elaborated by 3D printing and subsequent pyrolysis using microfibrillated cellulose/lignosulfonate/cellulose powder (labeled as MFC/LS/CP) blends. The processability of MFC/LS/CP slurries by 3D printing was examined by rheological tests in both steady flow and thixotropic modes. The printed MFC/LS/CP pastes were self-standing, provided a high printing definition and were proved to be morphologically stable to air drying and the subsequent pyrolysis. Pyrolysis at a slow rate (0.2 °C/min) to a final temperature ranging between 400 and 1200 °C was used to manufacture MFC/LS/CP carbons. The TGA/DTG was applied to monitor the thermal degradation of MFC/LS/CP materials in blends as well as in a separated form. The resulting carbons were further characterized in terms of morphology, microstructure and physical properties (such as density, electrical conductivity and mechanical strength). At 900 °C, MFC/LS/CP carbons displayed a high electrical conductivity of 47.8 S/cm together with a low density of 0.74 g/cm3 and a porosity of 0.58. They also achieved an elastic modulus of 6.62 GPa. Such interesting electrical and mechanical properties would lead to a promising application of MFC/LS/CP-derived biocarbons in energy storage devices as electrode materials in close future.

Abstract: Based on bottom-up assembly of highly variable neural cells units, the nervous system can reach unequalled level of performances with respect to standard materials and devices used in microelectronic. Reproducing these basic concepts in hardware could potentially revolutionize materials and device engineering which are used for information processing. Here, we present an innovative approach that relies on both iono-electronic materials and intrinsic device physics to show pattern classification out of a 12-unit bio-sensing array. We use the reservoir computing and learning concept to demonstrate relevant computing based on the ionic dynamics in 400-nm channel-length organic electrochemical transistor (OECT). We show that this approach copes efficiently with the high level of variability obtained by bottom-up fabrication using a new electropolymerizable polymer, which enables iono-electronic device functionality and material stability in the electrolyte. We investigate the effect of the array size and variability on the performances for a real-time classification task paving the way to new embedded sensing and processing approaches., Accepted manuscript, Adv.

Abstract: International audience; Cellulosic materials are very interesting for electronics industry. Cheap, environment friendly, easy to produce and flexible, they could be remarkable substrates. However, the poor properties of cellulose in regard to the ambient humidity rate is a real technological lock to the development of this very promising material. We propose, in this paper, to analyze and quantify the impact of humidity upon the RF properties of cellulose papers. The proposed theoretical model for the contribution of water to losses in the medium is validated by experimental results, and thus can help for the design of transmission lines on paper substrates.

Abstract: In this work, we propose a strategy to sense quantitatively and specifically cations, out of a single organic electrochemical transistor (OECT) device exposed to an electrolyte. From the systematic study of six different chloride salts over 12 different concentrations, we demonstrate that the impedance of the OECT device is governed by either the channel dedoping at low frequency and the electrolyte gate capacitive coupling at high frequency. Specific cationic signatures, which originates from the different impact of the cations behavior on the poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) polymer and their conductivity in water, allow their discrimination at the same molar concentrations. Dynamic analysis of the device impedance at different frequencies could allow the identification of specific ionic flows which could be of a great use in bioelectronics to further interpret complex mechanisms in biological media such as in the brain., Full text and supporting information

Abstract: International audience; The interest for cellulose nanocrystals and nanofibrils is exponentially increased since last decade thanks to their industrialization. In addition to their low density, high aspect ratio, high stiffness and Young’s modulus and chemically reactive surface, this material is well known for its high specific surface. Thanks to these particular properties, cellulose nanomaterials can be used within a wide variety of applications. Coating is one of the promising applications for nanocellulose mainly for barrier applications in packaging. Indeed new bio-based but also high performance solutions are expected in food packaging. Unfortunately, up to now, high barrier solutions can be provided but they always require a layer of thermosealing polymer which is usually fossil based. These multilayer materials are also more complicate to handle when end of life is considered. One solution would be to propose cellulosic materials which could be welded easily. Except thermosealing, ultrasounds welding have been developed in plastic industry last years.This study is a proof of concept that nanocellulosic materials can be welded by ultrasounds. Several nanocellulosic materials were firstly designed and characterized, i.e. from classic cellulose nanocrystals and nanofibrils to functionalized CNC by esterification with lauric acid. Than model films were prepared and welded by ultrasounds. Process parameters were optimized and successful welding were obtained and mechanically characterized. These very positive results have been patented and open the doors for new solutions in welding of biobased materials.

Abstract: High frequency paper-based electronics is developing fast, with smart yet low cost applications in view. However, the dielectric losses of paper remain a difficult hurdle to overcome. First, the literature on the topic is reviewed and the contributions from moisture, air, mineral filler, and wood constituents to dielectric losses are highlighted. Then, the guidelines for future research are defined, including the need for systematic comparisons in controlled moisture conditions. In an effort to produce low loss materials for paper-based electronics, it is proposed here to impregnate paper with a low loss substance, after removing residual water.

Abstract: Functionalization of polyoxotungstates with organoarsonate co-ligands enabling surface decoration was explored for the triangular cluster architectures of the composition [CoII9(H2O)6(OH)3(p-RC6H4AsVO3)2({\alpha}-PV2WVI15O56)3]25-({Co9(P2W15)3}, R = H or NH2), isolated as Na25[Co9(OH)3(H2O)6(C6H5AsO3)2(P2W15O56)3]86H2O (Na-1) and Na25[Co9(OH)3(H2O)6(H2NC6H4AsO3)2(P2W15O56)3]86H2O (Na-2). The axially oriented para-aminophenyl groups in 2 facilitate the formation of self-assembled monolayers on gold surfaces, and thus provide a viable molecular platform for charge transport studies of magnetically functionalized polyoxometalates. The title systems were isolated and characterized in the solid state and in aqueous solutions, and on metal surfaces. Using conducting tip atomic force microscopy (C-AFM), the energies of {Co9(P2W15)3} frontier molecular orbitals in the surface-bound state were found to directly correlate with cyclic voltammetry data in aqueous solution., Comment: Full paper with figures and supporting information

Abstract: In this paper, two monopole antenna structures called by the authors as “Hello 1” and “Hello 2” have been designed based on screen printing technology on the flexible paper substrate of 210-um thickness to cover very wide frequency range focusing on two WLAN bands. The designed antennas have the dimensions of 42 × 28 mm2 with the return loss of over 20 dB for “Hello 1”, and over 25 dB for “Hello 2” at both frequencies 2.45 GHz and 5.5 GHz. Both antennas have nearly omni-directional radiation patterns at 2.45 GHz while more directive at 5.5 GHz. The total efficiency of the antennas is of 67.3% and 68.9% at 2.45GHz, 65% and 67% at 5.5GHz for “Hello 1” and “Hello 2”, respectively. Two prototypes of each design have been realized and measured to compare with the simulation. As a result, acceptable agreement has been obtained.

Abstract: International audience; Production of nanofibrillated cellulose (CNF) has gained increasing attention during the last decades with its recent industrialization, but such a process consumes still too high of an amount of energy. Here, cellulose nanofibrils at high solid content (20–25 wt %) and consuming 60% less energy compared to conventional processes were produced from enzymatic and TEMPO-oxidized cellulose fibers thanks to a twin screw extruder equipped with kneading disks and fully flighted conveying screws. The morphology and properties of the produced CNF were characterized using optical microscopy, atomic force microscopy (AFM), mechanical properties, and light transmittance. CNF with a width in the range of 20–30 nm and mechanical properties close to those obtained with commercial CNF (Young’s modulus around 15 GPa) were produced. However, results from the degree of polymerization and crystallinity showed that twin screw extrusion (TSE) degrades the fibers as far as the supermasscolloider grinder is concerned. TSE appears as a new mechanical treatment that allows producing CNF at high solid contents and with low energy demand, which is a real asset for nanocellulose industrialization.

Abstract: This paper presents a wide-band monopole antenna structure printed on a flexible and low cost 104-um thick E4D paper. In order to begin the design process, electromagnetic properties of E4D paper were characterized using the cavity perturbation method with a cylindrical cavity. Then a microstrip fed antenna was designed and optimized to reach a good matching in a wide range of frequency, from 2 GHz to 10 GHz including two WLAN bands. The proposed antenna is thin, flexible, rather compact, has good performance with return loss of over 30 dB and 50 dB at 2.45 GHz and 5.5 GHz, respectively. It exhibits very large bandwidth, from 2 GHz to over 10 GHz. The radiation patterns are nearly omni-directional at both frequencies 2.45 GHz and 5.5 GHz. The design was realized by screen printing technology at CTP France. The measurement results for all six fabricated prototypes are in good agreement with the simulation that confirms the validity of the design.

Abstract: This study takes place in a context of development of paper-based barrier packaging materials, using of microfibrillated cellulose (MFC) that brings renewability, recyclability, and biodegradability. Two strategies have been investigated: the wet lamination of a MFC barrier layer on board, and the use of MFC as additive in a water-based barrier coating colour. The promising use of MFC for the formation of barrier layers has been demonstrated in both cases. The wet lamination of MFC on board led to good oxygen and grease barrier properties, using highly fibrillated MFC. The board-MFC complex presented a strong adhesion after drying, without requiring glue. In the case of barrier coating, in order to obtain a low viscosity suspensions leading to high barrier layers, the use of highly fibrillated MFC mixed with a fully-hydrolysed poly(vinyl alcohol (PVOH) of low degree of polymerisation has been preferred. The addition of MFC in PVOH demonstrated its potential for improving the drying behaviour of water-barrier barrier coating colours. The combined use of MFC and layered silicates evidenced a synergistic effect on their dispersion in a PVOH solution, leading to an improved water vapour barrier while avoiding the formation of aggregates that otherwise damage the oxygen barrier. The work contributed to demonstrate the potential of MFC to be used for the formation of barrier layers, paving the way for the development of more sustainable barrier packaging materials., Ce travail se situe dans un contexte de développement de matériaux barrières pour l'emballage alimentaire papier-carton utilisant des microfibrilles de cellulose (MFC), ce qui donne une dimension renouvelable, recyclable, et biodégradable. Pour cela, deux stratégies ont été étudiées : l'utilisation des MFC pour la formation d'une couche barrière laminée à l'état humide sur carton, et en tant qu'additif dans une sauce de couchage barrière base aqueuse. Il a été montré que l'utilisation des MFC pour la production de couches barrières est prometteuse dans les deux cas. La lamination de MFC sur carton a permis d'obtenir de bonnes propriétés barrières à l'oxygène et à la graisse en utilisant des MFC hautement fibrillées. L'association carton-MFC a présenté une forte adhésion après séchage, permettant d'éviter l'utilisation de colle. Dans le cas du couchage composite, en vue de diminuer la viscosité et améliorer la barrière, il a été trouvé préférable d'utiliser un faible taux de MFC dans un alcool polyvinylique (PVOH) complètement hydrolysé ayant un faible degré de polymérisation. L'ajout de MFC dans une sauce de couchage composite a montré leur capacité à améliorer la cinétique de séchage du PVOH. L’utilisation combinée de MFC et de charges lamellaires a présenté un effet de synergie sur leurs états de dispersions dans une solution de PVOH, permettant leur utilisation pour l'amélioration de la barrière à la vapeur d'eau en conditions humides, tout en évitant la formation d'agrégats qui détérioreraient la barrière à l'oxygène. Ce travail a contribué à démontrer le potentiel des MFC pour la formation de couches barrières, ouvrant la voie au développement de nouveaux matériaux d'emballages plus responsables.

Abstract: International audience; The fox tapeworm Echinococcus multilocularis is the causative agent of alveolar echinococcosis, a severe zoonotic disease that may be fatal if untreated. A broad spectrum of mammalian species may be accidentally infected even in captivity. In April 2011, liver lesions due to E. multilocularis were observed during the necropsy of a captive-born nutria (Myocastor coypus) in a French wildlife park, leading to initiation of a study to survey the parasite's presence in the park. A comparable environmental contamination with fox's feces infected by E. multilocularis was reported inside (17.8%) and outside (20.6%) the park. E. multilocularis worms were found in the intestines of three of the five roaming foxes shot in the park. Coprological analyses of potential definitive hosts in captivity (fox, lynx, wildcat, genet, wolf, bear and raccoon) revealed infection in one Eurasian wolf. Voles trapped inside the park also had a high prevalence of 5.3%. After diagnosis of alveolar echinococcosis in a Lemur catta during necropsy, four other cases in L. catta were detected by a combination of ultrasound and serology. These animals were treated twice daily with albendazole. The systematic massive metacestode development and numerous protoscoleces in L. catta confirmed their particular sensitivity to E. multilocularis infection. The autochthonous origin of the infection in all the captive animals infected was genetically confirmed by EmsB microsatellite analysis. Preventive measures were implemented to avoid the presence of roaming foxes, contact with potential definitive hosts and contaminated food sources for potential intermediate hosts.

Abstract: This paper presents a wallpaper filtering electromagnetic waves used in Wi-Fi transmissions. It is made of a frequency selective surface (FSS) printed on a paper substrate. The printing of conductive inks is done using industrial printing techniques. The FSS shows attenuation better than 25 dB for the first Wi-Fi band and better than 24 dB for the second one. The FSS pattern designed for this purpose is insensitive to the polarization and to the incidence angle of the electromagnetic waves up to ±60°.

Abstract: This paper describes a new setup for the measurement of transmission coefficient of materials. The proposed setup is a cheap and efficient way to obtain a good isolation between the transmission and reception antennas with a single room anechoic chamber. The dynamic range is better than 60 dB between 3 to 7 GHz and better to 40 dB in the range 0.7–3 GHz. Moreover, this measurement bench is easy to install and does not require modifying the configuration of the absorbents of the anechoic chamber. It is a excellent technique to measure the performances of Frequency Selective Surfaces (FSS).
