Nanocellulose has become a vital material with excellent and crucial properties in the field of nanotechnology and advanced materials science. Plant-based traditional Chinese medicines are mostly plant rhizomes, which contain a large amount of cellulose, hemicellulose, and lignin. In this study, carboxylated cellulose nanocrystals (CNCs) were prepared from traditional Chinese medicine residues (CMR) by sequential periodate-chlorite oxidation without mechanical treatment. The obtained nanocelluloses were analyzed by transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and X-ray diffractometry (XRD); the carboxyl content and specific surface area were also measured, simultaneously. XRD results revealed that the crystallinity index decreased after sequential oxidation; however, the cellulose I structure was maintained. From the morphology analysis, the average length and width of CNCs were 139.3 and 10 nm, respectively. From the FTIR analysis, with the particle size decreasing, hydrogen bonds were broken and recombined. TGA results showed that the thermal property was decreased with a reduction of nanocellulose particle size and crystallinity index. This study is the first to refine utilization of traditional Chinese medicine residues as a potential source of cellulose, that is, to prepare nanocellulose efficiently with high carboxyl content which finds its application in nanomaterials.

The squeeze casting technique offers promising prospects for a wide range of applications, as it provides an effective solution to address the challenges associated with the poor casting performance of wrought aluminum alloys. In this paper, we implemented in-situ forging assisted squeeze casting (IFSC) to form an automobile control arm using a high-strength Al–Zn–Mg–Cu alloy modified with Zr and Er. The solidification defects, microstructures, and mechanical properties of the part were investigated under different pressures and in-situ forging using various analytical techniques. With the increase of squeezing pressure from 0 MPa to 120 MPa, the ultimate tensile strength (UTS) of the sample increases from 500 MPa to 593.3 MPa, and the elongation is 4.35 %. After in-situ forging, the tensile strength of the sample is 600.9 MPa and the elongation is 5.59 %. UTS is comparable to squeeze casting, but the elongation is increased by 28.5 %. The results indicate that increasing the forming pressure enhances the surface quality of the parts and reduces the solidification defects. In addition, increasing the forming pressure not only refines the grain but also improves the grain morphology and enhances the uniformity of the structure. The squeezing pressure can enhance the contact between the alloy melt and the mold, increasing the metal's cooling rate and promoting nucleation for grain refinement. In-situ forging further facilitates liquid phase feeding, reduces alloy defects, and improves the overall mechanical properties.

Fibers of liquid crystal elastomers (LCEs) as promising artificial muscle show ultralarge and reversible contractile strokes. However, the contractile force is limited by the poor mechanical properties of the LCE fibers. Herein, we report high-strength LCE fibers by introducing a secondary network into the single-network LCE. The double-network LCE (DNLCE) shows considerable improvements in tensile strength (313.9%) and maximum actuation stress (342.8%) compared to pristine LCE. To facilitate the controllability and application, a coiled artificial muscle fiber consisting of DNLCE-coated carbon nanotube (CNT) fiber is prepared. When electrothermally driven, the artificial muscle fiber outputs a high actuation performance and programmable actuation. Furthermore, by knitting the artificial muscle fibers into origami structures, an intelligent gripper and crawling inchworm robot have been demonstrated. These demonstrations provide promising application scenarios for advanced intelligent systems in the future.

Chronic atrophic gastritis (CAG) is characterized by the loss of gastric glandular cells, which are replaced by the intestinal-type epithelium and fibrous tissue. Ginsenoside Rg1 (Rg1) is the prevalent ginsenoside in ginseng, with a variety of biological activities, and is usually added to functional foods. As a novel form of programmed cell death (PCD), pyroptosis has received substantial attention in recent years. Despite the numerous beneficial effects, the curative impact of Rg1 on CAG and whether its putative mechanism is partially via inhibiting pyroptosis still remain unknown. To address this gap, we conducted a study to explore the mechanisms underlying the potential anti-CAG effect of Rg1. We constructed a CAG rat model using a multifactor comprehensive method. A cellular model was developed by using 1-methyl-3-nitro-1-nitrosoguanidine (MNNG) combined with Nigericin as a stimulus applied to GES-1 cells. After Rg1 intervention, the levels of inflammatory indicators in the gastric tissue/cell supernatant were reduced. Rg1 relieved oxidative stress via reducing the myeloperoxidase (MPO) and malonaldehyde (MDA) levels in the gastric tissue and increasing the level of superoxide dismutase (SOD). Additionally, Rg1 improved MNNG+Nigericin-induced pyroptosis in the morphology and plasma membrane of the cells. Further research supported novel evidence for Rg1 in the regulation of the NF-κB/NLRP3/GSDMD pathway and the resulting pyroptosis underlying its therapeutic effect. Moreover, by overexpression and knockout of GSDMD in GES-1 cells, our findings suggested that GSDMD might serve as the key target in the effect of Rg1 on suppressing pyroptosis. All of these offer a potential theoretical foundation for applying Rg1 in ameliorating CAG.

Chemical modification of diamond surfaces generates a negative electron affinity (NEA), which shows great potential in realizing electron emission. In this study, zirconium (Zr) termination on clean and oxidized diamond (100) surfaces is theoretically proposed by using the structure prediction method, and electronic properties of these predicted surfaces are investigated by first-principles calculations. On the oxidized surfaces, the adsorption energy at 0.25 monolayer (ML) Zr coverage reaches a high value of −10.42 eV, further confirmed by the largest integrated crystal orbital Hamiltonian population value of 6.61 eV. For clean and oxidized diamond (100) surfaces, the largest NEA values at 0.25 ML Zr coverage are −3.75 eV and −3.45 eV, respectively. The dynamic stability of these surface structures is demonstrated by calculating phonon dispersion curves. Furthermore, ab initiomolecular dynamics simulations confirm the high thermal stability of the oxidized diamond surface. Therefore, these results indicate that Zr-terminated diamond (100) surfaces possess good thermal stability and higher NEA, making them promising candidate materials for electron emission applications.

The development of nanopesticides provides new avenues for pesticide reduction and efficiency improvement. However, the size effect of nanopesticides remains unclear, and its underlying mechanisms of influence have become a major obstacle in the design and application of pesticide nanoformulations. In this research, the noncarrier-coated emamectin benzoate (EB) solid dispersions (Micro-EB and Nano-EB) were produced under a constant surfactant-to-active ingredient ratio by a self-emulsifying-carrier solidification technique. The particle size of Micro-EB was 162 times that of spherical Nano-EB. The small size and large specific surface area of Nano-EB facilitated the adsorption of surfactants on the surface of the particles, thereby improving its dispersibility, suspensibility, and stability. The pinning effect of nanoparticles significantly suppressed droplet retraction and rebounding. Moreover, Nano-EB exhibited a 25% higher retention of the active ingredient on cabbage leaves and a 70% higher washing resistance than Micro-EB, and both were significantly different. The improvement of abilities in wetting, spreading, and retention of Nano-EB on crop leaves contributed to the increase in foliar utilization, which further resulted in a 1.6-fold enhancement of bioactivity against target Spodoptera exiguacompared to Micro-EB. Especially, Nano-EB did not exacerbate the safety risk to the nontarget organism zebrafish with no significant difference. This study elaborates the size effect on the effectiveness and safety of pesticide formulations and lays a theoretical foundation for the development and rational utilization of efficient and environmentally friendly nanopesticides.

Extensive research has been conducted on the structures and preparation methods of ceramic/metal composites to achieve materials with superior strength and toughness. Among these, the triply periodic minimal surface (TPMS) structure stands out due to its remarkable advantages. In this study, we employed SLA additive manufacturing to fabricate a Gyroid-structured ceramic skeleton, and utilized metal infiltration to prepare interpenetrating Al2O3/Al composites. A comparison was made between the compressive properties of Al2O3/Al interpenetrating composites with Gyroid curved surface structure and those with honeycomb structure. The experimental outcomes indicate that compressive failure in both structural composites primarily occurs at the bond interface between the ceramic framework and the metal. These composites exhibit brittle fracture and experience shear failure. Furthermore, the compressive failure mechanism involves a mixed fracture composed of cleavage and micropore polymerization fractures. Gyroid curved structural composites exhibit lower local stress concentration due to their smooth and regular topology, rendering them with higher strength and ductility compared to honeycomb structural composites. The ultimate compressive strength of the Gyroid curved composite is 264 MPa, representing a 3.8-fold increase over the honeycomb structure.

Morphing textiles, crafted using electrochemical artificial muscle yarns, boast features such as adaptive structural flexibility, programmable control, low operating voltage, and minimal thermal effect. However, the progression of these textiles is still impeded by the challenges in the continuous production of these yarn muscles and the necessity for proper structure designs that bypass operation in extensive electrolyte environments. Herein, a meters-long sheath-core structured carbon nanotube (CNT)/nylon composite yarn muscle is continuously prepared. The nylon core not only reduces the consumption of CNTs but also amplifies the surface area for interaction between the CNT yarn and the electrolyte, leading to an enhanced effective actuation volume. When driven electrochemically, the CNT@nylon yarn muscle demonstrates a maximum contractile stroke of 26.4%, a maximum contractile rate of 15.8% s–1, and a maximum power density of 0.37 W g–1, surpassing pure CNT yarn muscles by 1.59, 1.82, and 5.5 times, respectively. By knitting the electrochemical CNT@nylon artificial muscle yarns into a soft fabric that serves as both a soft scaffold and an electrolyte container, we achieved a morphing textile is achieved. This textile can perform programmable multiple motion modes in air such as contraction and sectional bending.

Lung cancer is one of the malignancies with the highest incidence and mortality rates worldwide, and non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancer types. In this study, the anti-cancer activities of a novel flurbiprofen organic selenium compound, RY-1-92, on NSCLC cells and a mouse model and the underlying molecular mechanisms were explored. We found that compound RY-1-92 can significantly inhibit the viability, colony formation and migration of A549, NCI-H460 lung cancer cells. Flow cytometry analysis showed that RY-1-92 also can lead to G2/M cell cycle arrest and apoptosis induced in lung cancer cells. Further, RY-1-92 can decrease the tumor size in the Lewis lung cancer tumor-bearing mouse model. The protein levels of cell cycle-related proteins CDK1/cyclinB1 were decreased, while the apoptosis-related protein BAX was increased dramatically after RY-1-92 treatment in vitroand in vivo. Impressively, it was found that TRPV1 might act as a potential molecular target of RY-1-92 using the SEA search server. Furthermore, down-regulation on TRPV1 and its downstream associated factors including p-AKT protein and MAPK signaling pathway-related proteins after RY-1-92 treatment was observed in A549, NCI-H460 lung cancer cells. Taken together, our findings shed light on the potential of RY-1-92 as a novel small molecular drug for NSCLC, and it is of great significance for its further in-depth research and development.

Chiral drug molecules play an important role in the treatment of diseases and public health; however, these substances are often difficult to be separated from nonchiral molecules in the chemical production process. Here, a chiral molecule, 3,5-dibromo-l-tyrosine, is adopted as the building monomer to cross-link with 1,3,5-tris(4-ethynylphenyl)benzene through the Sonogashira–Hagihara coupling reaction to obtain the chiral PAF solid, LNU-56. Because we have successfully introduced chiral amino acid groups into the pores with a diameter of 1.2 nm, the obtained adsorbent shows outstanding adsorption capability for ketoprofen drug, with a maximum capacity of 725.56 mg g–1, which is the highest adsorption capacity reported so far. Meanwhile, synergetic patterns of chiral fragments and steric confinement bring about the high selectivity for chiral pharmaceuticals in the presence of various achiral drugs, various interfering ions, or high concentration of NaCl. The advantages of constructing a chiral porous platform provide new perspectives on the development of PAF-based adsorbents and separation and purification of pharmaceuticals.

Similar to natural muscle fibers, coiled artificial muscle fibers provide a straightforward contraction. However, unlike natural muscle fibers, their recovery from the contracted state to the initial state requires high stress, resulting in almost zero work during a full actuation cycle. Herein, a self-recoverable coiled artificial muscle fiber was prepared by conformally coating an elastic carbon nanotube (CNT) fiber with a very thin liquid crystal elastomer (LCE) sheath. The as-obtained muscle fiber demonstrated excellent actuation properties comprising 56.9% contractile stroke, 1522%/s contraction rate, 7.03 kW kg–1power density, and 32,000 stable cycles. The LCE chains were helically aligned in a nematic phase, and the phase change of the LCE caused by Joule heating drove the actuation process. Moreover, the LCE/CNT fiber had a well-separated, torsionally stable, and elastic coiled structure, which permitted large contractile strokes and acted as an elastic template for external-stress-free recovery. Thus, the use of self-recoverable muscle fibers to mimic the natural muscles for object dragging, multidirectional bending, and quick striking was demonstrated.

Graphene has recently gained significant interest as a promising lubricant and additive for metal matrix composites. In this work, the microstructure and tribological properties of Mg-based composites were systematically investigated by introducing nano-ZnO modified graphene. It was found that graphene can be uniformly distributed in Mg matrix. In addition, MgO, the interfacial reaction product with nanoscale structure, can enhance the interfacial bonding strength of the composite. Compared to pure Mg matrix, the composite shown significant improvements in hardness and wear resistance. Finally, the mechanism of the wear resistance of the composite was discussed. This work provides technical support and theoretical guidance for the preparation and design of metal matrix composite with high wear resistance.

Private key (e.g., RSA key) protection is a significant issue for cloud but existing keyless or keyguard solutions suffer from performance, elasticity or applicability limitations. Recently, represented by Intel KPT, a novel keyguard architecture emerges to combine trusted platform module and crypto accelerator for achieving both security and performance. However, the straight use of KPT for private key protection may not be a good fit in cloud as it incurs challenges on protection capacity, key provisioning latency and transparency. Based on KPT-like hardware, we propose QKPT, a comprehensive key management system to bring your own private keys (BYOPK) into multi-tenant clouds. QKPT introduces a carefully-designed key wrapping layer to overcome these challenges. A small symmetric wrapping key (SWK) is generated for each tenant as the master key to resolve the former two challenges, while a special private key wrapping scheme is adopted to resolve the transparency limitation. Additionally, QKPT incorporates certificate trust to enhance the security of the SWK lifecycle and provides a hardened key server solution without expensive HSM. The evaluation shows that QKPT has a low runtime overhead ($\leq$≤ 1.2% for SSL/TLS handshakes) and still greatly outperforms the software baseline (3.5x-17x) owing to the crypto offloading.

Long noncoding RNAs (lncRNAs) have been demonstrated to participate in various biological processes and play key roles in tumorigenesis and metastasis. Pituitary adenoma (PA) is one of the most common malignancies in central nervous system. Recently, multiple lncRNAs have been identified to regulate PA initiation, progression and metastasis. we aimed to elucidate the expression pattern and function of lncRNA MYMLR in PA development. The expression of lncRNA MYMLR in PA tissues and cells was examined by real-time quantitative PCR. Knockdown of MYMLR expression was achieved by using shRNA. The function of MYMLR and regulatory network were analyzed using CCK-8 assay, wound-healing assay, migration assay and Annexin V/PI staining. Xenograft tumor model was used to explore the function of MYMLR in vivo. Bioinformatics analysis and luciferase reporter assay were conducted to investigate the interaction between MYMLR and its regulatory network. LncRNA MYMLR was highly expressed in PA tissues compared with that in normal tissues. Knockdown of MYMLR suppressed cell proliferation, migration and invasion, while promoting PA cell apoptosis. Mechanistically, MYMLR functioned as a competing endogenous RNA (ceRNA) sponging microRNA miR-197-3p. Furthermore, miR-197-3p exerted its tumor inhibitory role via negatively regulating carbonyl reductase 1 (CBR1). Overexpression of CBR1 antagonized the inhibitory effect of lncRNA MYMLR knockdown or miR-197-3p overexpression. In addition, xenograft tumor model revealed that knockdown of lncRNA MYMLR suppressed PA tumor development in vivovia regulating CBR1. Our findings suggest a regulatory network of lncRNA MYMLR/miR-197-3p/CBR1, which benefits the understanding of PA development and provides a promising lncRNA-direct therapeutic strategy against PA.

Lepidopteraninsects constitute one of the largest fractions of animals on earth, but most are considered pests in their relationship with humans. In particular, the midgut is the primary site of digestion and absorption, which is alkaline and contains many alkaline proteases. In current pesticide preparation, zein can be used as an ideal carrier material due to its antioxidation properties, biocompatibility, low cost, and adhesion. Moreover, zein is stable in gastric acid but can be soluble in alkaline solution or degraded by alkaline proteases in the intestine. Herein, a pH/enzyme dual-responsive zein–EMB–nanocapsule (zein-EMB-NC) system was prepared to enhance the pesticide's adhesion, target wettability, stability, anti-photolysis, and stimuli-responsive controlled release properties. Scanning electron microscopy, transmission electron microscopy, and dynamic light scattering were applied to investigate their structural characteristics and stability, from which it was found that zein-EMB-NC formed uniform nanoparticles with an average diameter of 156.9 ± 0.6 nm and had excellent stability in aqueous solution. As confirmed by ultraviolet-visible spectroscopy, the anti-UV properties of zein-EMB-NC revealed that the presence of zein could protect EMB from UV photolysis. The foliar surface adhesion and wettability performance of zein-EMB-NC are significantly improved through hydrophobic interactions and hydrogen bonding. The toxicity of zein-EMB-NC to Spodoptera exigua(Hübner) was significantly higher than that of three commercially available formulations tested. The application of foliar spraying on peanuts against Spodoptera exigua(Hübner) shows that a 60% dose of zein-EMB-NC retained a control efficacy similar to that of commercialized samples. Overall, this novel zein-EMB-NC has broad prospects in crop protection by improving insecticidal activity and reducing pesticide loss.

Graphical Abstract:

AbstractA new solution for the longitudinal displacement profile (LDP) is proposed based on three-dimensional finite-difference method. The improved convergence-confinement method (CCM) is divided into two stages. In the first stage, the fictitious support pressure can be derived, representing the support pressure acting on the periphery of the tunnel by the rock mass itself. In the second stage, the fictitious support pressure transforms to the pressure on liner, and this progress reflects the interaction between rock mass and liner. According to two-stage analysis, a computing procedure is proposed for calculating pressure and deformation of rock and liner. By comparing with the results of other approaches, the procedure is proved to be correct. The influences of elasticity modulus, thickness of liner, and supporting time are discussed individually. The results indicate that the final pressure on liner can be reduced by reducing stiffness of liner and postponing supporting time. To prevent the liner from yielding, the prior measure is to postpone supporting time, and meanwhile, the liner with lower elasticity modulus and smaller thickness can be selected. In final, a practical example is performed by utilising this procedure, confirming it can provide reference to tunnel engineering design.

Cellulose and tannin are both abundant and biodegradable biopolymers, whose integrations show great potential in the food field due to their nutritional properties and biological activity. Here, lignocellulose nanocrystals (LCNC) isolated from pineapple peel were complexed with tannic acid (TA) through hydrogen-bonding interaction to prepare the LCNC/TA complex for stabilizing Pickering emulsions. Introducing TA decreased the interfacial tension (23.8–20.1 mN/m) and water contact angle (83.2–56.2°) with the LCNC/TA ratio ranging from 1:0 to 1:0.8 (w/w) but increased the size of the LCNC/TA complex. The droplet size of emulsions decreased from 115.0 to 51.3 μm accompanied by improved rheological properties. The emulsions stabilized by the LCNC/TA complex exhibited higher storage and environmental stabilities than those stabilized by LCNC alone. Interestingly, TA effectively promoted the interfacial adsorption of LCNC to build a stronger interfacial layer. The emulsion network structure was enhanced due to the formation of hydrogen-bonding interaction between LCNC and TA in the continuous phase.

Porous carbon nanofibers with unique hierarchical structures have great potential in many fields, including heterogeneous catalysis, optoelectronics, and sensing. However, several preparation issues, such as additional templates, complicated processes, and harsh conditions, seriously hamper their widespread use. Here, we control the Sonogashira coupling reaction of linear building monomers─1,4-dibromaphthalene and 1,4-ethylbenzene─at the molecular level. Due to the occurrence of branching chain reaction (side reaction), 1D oligomer expands the growth orientation in the plane direction, forming a curled 1D fiber polymer. After thermal-driven skeleton engineering, porous carbon nanofibers were obtained with hierarchical channels of macro- (150 nm), meso- (5.2 nm), and microcavities (0.5 and 1.3 nm). The integration of macro-/meso-/microporous structure reveals a fast and sufficient interaction with electrolyte molecules, facilitating the construction of high-performance electrical devices. Our strategy, using a side reaction to achieve the dimensionality control of 1D copolymerization, paves a new way for the facile preparation of porous carbon nanofibers.

ABSTRACTGlioma is one of the most aggressive malignancies in the central nervous system and the prognosis of glioma patients remains poor. In this study, we investigated the function of microRNA-30e-3p (miR-30e-3p) in glioma development and its regulatory role in drug-resistance to temozolomide (TMZ). We found that miR-30e-3p was downregulated in glioma tissues and cell lines. Ectopic expression of miR-30e-3p inhibited the growth of glioma cells and arrested cell cycle at G0/G1 phase. Canopy FGF signaling regulator 2 (CNPY2) was predicted as a direct target of miR-30e-3p by bioinformatics analysis. Luciferase reporter assay confirmed the interaction between miR-30e-3p and CNPY2. We also demonstrated that miR-30e-3p suppressed glioma xenograft tumor development invivoand the inhibition was abolished by CNPY2 overexpression. In addition, we showed that overexpression of miR-30e-3p enhanced the sensitivity of glioma cell to TMZ treatment. Glioma cells with miR-30e-3p overexpression had decreased cell proliferation and enhanced cell apoptosis upon TMZ treatment. Moreover, we revealed that miR-30e-3p modulated TMZ sensitivity of glioma cells via negatively regulating CNPY2. Taken together, our findings demonstrate that miR-30e-3p plays a critical role in glioma development and drug sensitivity to TMZ treatment via negatively regulating CNPY2 expression. The study suggests that miR-30e-3p/CNPY2 could be developed as a novel target to improve the glioma therapy.Abbreviations:miR-30e-3p, microRNA-30e-3p; TMZ, temozolomide; CNPY2, canopy FGF signaling regulator 2; 3ʹ-UTR, 3ʹ untranslated region; NC, negative control.

ABSTRACTBackgroundhsa_circ_0006168 is an oncogenic circular RNA in esophageal cancer. However, its role remains unclarified in tumor progression of gliomas, especially in glioblastoma (GBM).MethodsCell counting kit-8 assay, transwell assays, western blotting, and xenograft experiment, as well as colony formation assay and flow cytometry were performed to measure cell proliferation and motility. Expression of hsa_circ_0006168, microRNA (miR)-628-3p, insulin‑like growth factor 1 receptor (IGF1R), and Ras/extracellular signal regulated kinases (Erk)-related proteins were determined by quantitative real-time polymerase chain reaction and western blotting. The physical interaction was confirmed by dual-luciferase reporter assay and RNA pull-down assay.Resultshsa_circ_0006168 and IGF1R were upregulated, and miR-628-5p was downregulated in human GBM tissues and cells. Functionally, blocking hsa_circ_0006168 and overexpressing miR-628-5p suppressed cell proliferation, migration, invasion, and expression of Vimentin and Snail (mesenchymal markers) in A172 and LN229 cells, accompanied with increased E-cadherin (epithelial marker), decreased colony formation, and promoted apoptosis rate. Silencing miR-628-5p counteracted the suppression of hsa_circ_0006168 deficiency on these behaviors, and restoring IGF1R blocked miR-628-5p-mediated inhibition as well. More importantly, hsa_circ_0006168 knockdown could delay xenograft tumor growth in vivoand lower Ras and phosphorylated Erk1/2 expression in vitroand in vivo. Mechanically, hsa_circ_0006168 targeted and sponged miR-628-5p, and IFG1R was a novel target for miR-628-5p. Inhibiting miR-628-5p could abrogate in vitrorole of hsa_circ_0006168 knockdown, and similarly IGF1R upregulation counteracted miR-628-5p role.ConclusionSilencing hsa_circ_0006168 might suppress GBM proliferation and motility via serving as competitive endogenous RNA for miR-628-5p and regulating IGF1R/Ras/Erk pathway.

This Letter demonstrates a novel, to the best of our knowledge, method to measure the fluence distribution of an intense short laser pulse based on the radiochromic effect. We discovered that an intense short laser pulse can induce the color reaction with a radiochromic film (RCF). Further, the net optical density of an irradiated RCF is proportional to the fluence of the incident laser pulse in a large range (${2 {-} 120}\;{{{\rm mJ}/{\rm cm}}^2}$). This method supports a large detection area up to near square-meter scale by splicing multi-pieces of RCFs (${8} \times 10\;{{\rm inch}^2}$ each). The spatial resolution reaches as high as 60 lines/mm. It offers a thin-film (${\sim}{100}\;{\unicode{x00B5}{\rm m}}$ thick), flexible, vacuum-compatible solution to intense short laser measurements, especially to laser facilities above petawatt, with beam sizes up to near square-meter scale, e.g., extreme light infrastructure.
