The frozen elephant trunk technique has revolutionized aortic arch repair to enable more extensive arch and descending thoracic aortic treatment in a single setting. We review the current evidence supporting the use of the Thoraflex Hybrid (Terumo Aortic, FL, USA) device and discuss advantages, pitfalls and future design considerations.Lay abstract Disease of the aorta, the biggest blood vessel in the body, is challenging. In recent years, new technologies such as the frozen elephant trunk (FET) have improved the treatment of patients with these complicated diseases. The FET is a hybrid device, made of medical fabrics and a covered metal stent (a tube inserted into the blood vessel to keep it open). In this paper, we provide an in-depth review of a FET device known as Thoraflex Hybrid (Terumo Aortic, FL, USA). We discuss its advantages and pitfalls as well as future areas of research.

Compared to SiC MOSFET, the switching loss of Si IGBT is much higher due to its slow switching speed and tail current. Si IGBT/SiC MOSFET hybrid switch device can reach to optimal performance with low static and dynamic loss, which can improve the current capacity of SiC devices and reduce the power loss of Si IGBT based converters. With the separated gate control signals, the switching moments of the two devices can be controlled independently to ensure Si IGBT under zero-voltage switching (ZVS) conditions. This measurement tends to reduce the switching loss of Si IGBT. However, the switching time delay between these two devices has significant impacts on its power loss. In this paper, the switching time delay optimization method is proposed to minimize the power loss of the hybrid switch. The static and dynamic characteristics of Si IGBT/SiC MOSFET hybrid-paralleled switch are studied, and a generalized power loss model for hybrid switch is developed. The influence of switching time delay on the characteristics of hybrid switch is analyzed and verified through double pulse tests in a phase-leg configuration. The experimental results show that the optimal turn-on delay time is that the two devices turn on at the same time and the turn-on loss can be reduced by about 73% compared with the solely Si IGBT and by about 52% compared with the solely SiC MOSFET. While the optimal turn-off sequence is that the Si IGBT turns off ahead of the SiC MOSFET. Under the proposed optimal turn-off delay time of the hybrid switch, the turn-off loss is reduced by about 61.4%. This optimization strategy is used in a Buck converter to verify the superiority of the SiC/Si hybrid switch and the optimal switching sequence. Simulation results show that the optimal switching sequence is consistent with theoretical analysis, and the efficiency is improved by 2.5% compared with Buck converter using solely Si IGBT.

A partir de la configuración visual de diferentes objetos de diseño chileno, este artículo realiza un análisis comparativo entre objetos de diseño producidos en Chile a inicios del siglo XXI y objetos producidos por la Bauhaus a inicios del siglo XX en Alemania. Desde un análisis visual que incluye a seis diseñadores y arquitectos chilenos que exploran el diseño de objetos y mobiliario, se analizan las categorías experimentación y racionalidad dentro de la producción objetual chilena, desde un enfoque fenomenológico y comparativo con la producción objetual que hicieron académicos, estudiantes y diseñadores egresados de la Bauhaus. Observamos que al igual que en los métodos académicos de la Bauhaus, en el diseño chileno los cruces entre procesos productivos artesanales e industriales siguen vigentes, estableciendo vínculos que a pesar de la mediación tecnológica actual, continúan creando instancias de hibridación para abordar el proceso de diseño desde ambas dimensiones, la de una experimentación intuitiva y la de un racionalismo formal. Finalmente se indaga en cómo la configuración de las alteridades, experimentación y racionalismo, en el diseño propuesto por la Bauhaus, generó un dispositivo híbrido, que logró articular un principio de variedad dentro de la unidad, favoreciendo la convivencia de diferentes corrientes creativas bajo un programa común en torno al funcionalismo, pero sin anular estas dos dimensiones que puede alcanzar el diseño, haciendo de dichas diferencias, un elemento constitutivo de su identidad.

Objective The aim of this study was to assess the efficacy of the “SMARTLock” hybrid system and determine whether it results in fewer intraoperative and postoperative complications compared with placement of intermaxillary fixation (IMF) screws in trauma patients. Study Design This prospective study, which was approved by the institutional review board, compared the results of MMF in mandibular fractures by using the Stryker “SMARTLock” hybrid system versus traditional IMF screws. Patients were recruited and assigned randomly to either group. The 2 groups were compared for placement time, intraoperative complications, loosening of hardware, postoperative complications, and time to device removal. Results We enrolled 32 patients in the study, with 13 patients randomized to the group receiving hybrid MMF (HMMF) with the SMARTLock system and 19 to the group of patients receiving MMF with traditional IMF screws. The mean application time for HMMF was 25.92 minutes compared with 18.28 minutes for IMF screws. After removal, the HMMF was associated with gingival overgrowth and gingival edema. Conclusions This is the first study to compare HMMF with MMF with the use of IMF screws. Hybrid arch bars do require more manipulation for ideal placement compared with individually placed bone screws to achieve ideal MMF. Compared with IMF screws, the hybrid device was associated with gingival edema and overgrowth, but there was decreased incidence of loosening in the postoperative period.

The Ni3S2/Ni(OH)2 electrode could deliver a high areal capacity of 1.58 C/cm2 at 2 mA/cm2, along with outstanding cycling stability (113% capacity retention after 30,000 cycles). The energy density of the Ni3S2/Ni(OH)2//AC hybrid device was 30.23 Wh/kg at a power density of 155 W/kg (15.5 Wh/kg at 3,875 W/kg). Compared with other Ni(OH)2 composites on Ni foam, these results indicate that Ni3S2/Ni(OH)2 directly grown on Ni foam opens up the potential application for energystorage devices with high areal capacity and high cycling performance.

OBJECTIVE To evaluate the accuracy of the InBody BPBIO210 manual auscultatory mercury-free hybrid blood pressure (BP) measuring device for professional office use in a general population according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard (ISO 81060-2:2018). METHODS Subjects were recruited to fulfil the age, sex, BP and cuff distribution criteria of the AAMI/ESH/ISO Universal Standard in a general population using the same arm sequential BP measurement method. Two cuffs of the test device were used for arm circumference 22-32 (medium) and 32-42 cm (large). RESULTS A total of 94 subjects were recruited and 86 were analysed (mean age 53.7 ± 18.4 [SD] years, 50 men, arm circumference 32.5 ± 4.8 cm, range 22-42 cm). For the validation Criterion 1, the mean ± SD of the differences between the test device and reference BP readings was -1.0 ± 4.1/-0.7 ± 2.5 mmHg (systolic/diastolic). For Criterion 2, the SD of the averaged BP differences between the test device and reference BP per subject was 2.65/1.59 mmHg (systolic/diastolic). CONCLUSIONS The InBody BPBIO210 manual auscultatory hybrid device for professional office BP measurement fulfilled all the requirements of the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018) in a general population and can be recommended for clinical use.

Reimplantation of the supra-aortic vessels can be challenging with Thoraflex Hybrid. A device modification made the vessel lengths more appropriate and the position of the neo-vessels in the chest avoided malpositioning and kinking and facilitated sternum closure; this may improve operating times as well as allowing complete and continuous cerebral trivascular perfusion and corrects positioning of the intrathoracic vessels.

Solid-state quantum emitters coupled with a single mode fibre are of interest for photonic and quantum applications. In this context, nanofibre Bragg cavities (NFBCs), which are microcavities fabricated in an optical nanofibre, are promising devices because they can efficiently couple photons emitted from the quantum emitters to the single mode fibre. Recently, we have realized a hybrid device of an NFBC and a single colloidal CdSe/ZnS quantum dot. However, colloidal quantum dots exhibit inherent photo-bleaching. Thus, it is desired to couple an NFBC with defect centres in hexagonal boron nitride (hBN) as stable quantum emitters. In this work, we realize a hybrid system of an NFBC and defect centres in hBN nanoflakes. In this experiment, we fabricate NFBCs with a quality factor of 807 and a resonant wavelength at around 573 nm, which matches well with the fluorescent wavelength of the defect centres in hBN, using a helium focused ion beam (FIB) system. We also develop a manipulation system to place hBN nanoflakes on a cavity region of the NFBCs and realize a hybrid device with an NFBC. By exciting the nanoflakes via an objective lens and collecting the fluorescence through the NFBC, we observe a sharp emission peak at the resonant wavelength of the NFBC.

Foldables and 2-in-1 devices provide users with new ways to adapt their device to their mobile context, allowing users to switch device configuration, screen size and shape, and input mechanism in seconds. This has strong implications for the design of interactive media applications that need to adapt to the user's changing context and device parameters. In this study, we explored how users opportunistically make use of these new device affordances in their everyday lives through interviews with 15 diverse hybrid device owners, identifying use cases and pain points. Users reported regularly moving through multiple configurations or input modes while using a single product, or completing a single task. Based on our learnings, we provide recommendations for practitioners designing for hybrid mobile devices.

BACKGROUND Radiofrequency is a commonly used method to non-invasively tighten the skin that can be safely applied to any skin type. AIMS The aim of our study was to evaluate the safety and efficacy of the focused radiofrequency and ultrasound hybrid device for face and neck rejuvenation, in terms of improvement of facial wrinkles and jaw sagging. METHODS A total of 158 patients had undergone four weekly sessions of focused radiofrequency and ultrasound to face and neck area. Photodocumentation was obtained before first visit and two weeks after last visit. An independent, blinded dermatologist evaluated the severity of wrinkles and sagging of seven different anatomical regions on a validated scale of 0-4 (0: no lines/sagging, 1: mild, 2: moderate, 3: severe, 4: very severe) before and after the procedure. Patients rated their satisfaction with the result of the treatment on a scale of 1-5 (1: dissatisfied, 2: poorly satisfied 3: satisfied, 4: very satisfied, 5: perfectly satisfied). RESULTS For seven anatomical regions, statistically significant reduction was observed in mean wrinkle/sagging scores (p =

Treatment of transverse maxillary deficiency requires maxillary expansion. Therefore, assessing the midpalatal suture maturation stage through CBCT is essential for treatment choice between RPE, MARPE, and SARPE, although it is not without risk of clinical error. In young adults with a potential suture opening, MARPE can be attempted unless in the following situations, where SARPE is advisable: large expansions (>5 mm) and the necessity of additional maxillary forward or downward movement.

The performative installation piece Peri-Sphere, resulting from collaborative artistic research on expanded choreography by dancer-choreographer Benjamin Vandewalle and researchers Dieter Brusselaers and Helena Julian, delves into the possibility of choreographing not for, but with the very gaze of the audience. This way, the project touches upon a theme continuously reformulated by Vandewalle in his oeuvre of dance and performance. This chapter documents the research on Peri-Sphere, and particularly questions how its outcome creates a discursive/material hybrid space in which an experiencer’s body is invited as the final component completing an immersive automaton. In this process of laying bare the internal cogs of theatricality, Peri-Sphere becomes a discursive body of knowledge, as well as a material apparatus mediating and instrumentalizing an immersive experience.

Peptide nucleic acid (PNA) is a synthetic DNA mimic that outperforms the properties of traditional oligonucleotides (ONs). On account of its outstanding features, such as remarkable binding affinity towards complementary DNA or RNA as well as high thermal and chemical stability, PNA has been proposed as a valuable alternative to the ON probe in gene-sensor design. In this study, a hybrid transducer made-up of graphene oxide (GO) nano-sheets covalently grafted onto a porous silicon (PSi) matrix has been investigated for the early detection of a genetic cardiac disorder, the Brugada syndrome (BS). A functionalization strategy towards the realization of a potential PNA-based device is described. A peptide nucleic acid (PNA), able to detect the SCN5A associated with the BS has been properly synthesized and used as a bioprobe for the realization of a proof-of-concept label-free optical PNA-biosensor. PSi reflectance and GO photoluminescence (PL) signals were simultaneously exploited for the monitoring of the device functionalization and response.

The monitoring of respiratory disorders requires breath sensors that are fast, robust, and convenient to use and can function under real time conditions. A MOF based flexible sensor is reported for the first time for breath sensing applications. The properties of a highly porous HKUST-1 MOF and a conducting MoS2 material have been combined to fabricate an electronic sensor on a flexible paper support for studying sleep apnea problems. Extensive breath sensing experiments have been performed and interestingly the fabricated sensor is efficient in detecting various kinds of breaths such as deep, fast, slow and hydrated breath. The MOF breath sensor shows a fast response time of just ∼0.38 s and excellent stability with no decline in its performance even after a month. A plausible mechanism has been proposed and a smartphone based prototype has been prepared to demonstrate the real time applications of the hybrid device. This work demonstrates great potential for the application of MOFs in healthcare with a special focus on breath sensing and sleep apnea diagnosis.

International audience; The paper presents a new dual transducer and its associated control law. It aims to increase the efficiency of a traditional passive damped electromagnetic resonator by controlling its mass response actively. The design aspects of the so-called Dual-Loop Controller (DLC) for Hybrid Mass Damper (HMD) are presented and discussed. The control law attempts to modify a Tuned Mass Damper (TMD) to use it as an Active Mass Damper (AMD), with the objective of combining the best of the two technologies by actively increasing the performance of the passive device. Based on an optimally tuned passive device, the resulting system is fail-safe. The conception of the new dual transducer used as an HMD, designed specifically for this control law, is detailed. The hybrid device is experimentally validated both on a laboratory setup and on a real helicopter.

In this letter, we demonstrate a new concept of threshold selector by combining Ag-based selector with NbO x insulator metal transition (IMT) selector. To overcome intrinsic limits of slow turn-off speed ( $> 1\mu \text{s}$ ) of the Ag-based selector, we adopted NbO x IMT selector with fast turn-off speed. The hybrid device exhibits excellent selector characteristics, such as extremely low off-current ( $ ). It shows excellent read-out margin (>75% at >210 word lines) in a fast sequential operation of cross point memory array.

International audience; Niobium pentoxide, Nb2O5, exists in many polymorphs with diverse properties and morphologies that are dependent on the synthesis route. In this work, we design a new approach to fabricate and stabilize the metastable polymorph hexagonal nano-niobium pentoxide using soft chemistry and in particular the polyol synthesis. The electrochromic properties of homogeneous niobium pentoxide thin films deposited by dip coating, from as-synthesized hexagonal powder, are studied in lithium trifluoromethanesulfonimide (LiTFSI) in 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (EMITFSI) ionic liquid electrolyte versus Pt as counter electrode. The structure and morphology of the Nb2O5 thin films before and after cycling are characterized by ex-situ XRD and SEM while their optical and electrochemical properties are investigated by in-situ transmittance and cyclic voltammetry (CV), respectively. Thin films made from hexagonal Nb2O5 with a sphere architecture exhibit good cycling stability, high transmittance modulations (ΔT ≈ 33% at 550 nm), fast switching speeds (2–3 s for coloration and bleaching at 550 nm), and high coloration efficiency (CE ≈ 26 cm2 C–1) with a good quality factor G(λ) = 10.4 cm2 C–1 s–1. Finally, novel electrochromic devices based on hybrid thin films combining poly(ethylene-3,4-dioxythiophene):poly(styrenesulfonicacid) (PEDOT:PSS) and oxides are assembled showing enhanced coloration and simultaneous color change due to their double-sided configuration.

In this study, polyethersulfone (PES) paper embedded with a polymethyl methacrylate (PMMA) platform was developed for simultaneous DNA amplification and colorimetric detection. DNA was amplified using loop-mediated isothermal amplification (LAMP) in isothermal conditions in the presence of the common magnesium-dependent colorimetric indicator, eriochrome black T (EBT), to detect DNA. Here, the DNA of Staphylococcus aureus was used as the DNA template. The developed device was successfully used to simultaneously amplify and detect the DNA by the naked eye within 30 min with a detection limit of 1 fg/µL.

The heterogeneous Ni(OH)2/CuCo2S4/Ni electrode is constructed by appropriately adjusting the time-dependent hydrothermal and electrodeposition process. A hybrid device exhibits 39.7 W h kg−1 of specific energy and 365.3 W kg−1 of specific power, with a good cycling stability of 88% capacity retention after 5000 cycles at 6 A g−1.

peer-reviewed The full text of this article is not available until the embargo expires on the 11/7/2019 Enzymatic biofuel cells can generate electricity directly from the chemical energy of biofuels in physiological fluids, but their power density is significantly limited by the performance of the cathode which is based on oxygen reduction for in vivo applications. An oxygen-independent and membrane-less glucose biobattery was prepared that consists of a dealloyed nanoporous gold (NPG) supported glucose dehydrogenase (GDH) bioanode, immobilised with the assistance of conductive polymer/Os redox polymer composites, and a solid-state NPG/MnO2 cathode. In a solution containing 10 mM glucose, a maximum power density of 2.3 µW cm−2 at 0.21 V and an open circuit voltage (OCV) of 0.49 V were registered as a biobattery. The potential of the discharged MnO2 could be recovered, enabling a proof-of-concept biobattery/supercapacitor hybrid device. The resulting device exhibited a stable performance for 50 cycles of self-recovery and galvanostatic discharge as a supercapacitor at 0.1 mA cm−2 over a period of 25 h. The device could be discharged at current densities up to 2 mA cm−2 supplying a maximum instantaneous power density of 676 μW cm−2, which is 294 times higher than that from the biobattery alone. A mechanism for the recovery of the potential of the cathode, analogous to that of RuO2 (Electrochim. Acta 42(23), 3541–3552) is described.

In the present work, fabrication, characterizations and gas sensing performance of a novel ternary hybrid junction device consisting of Pd nanoparticles, Reduced Graphene Oxide (RGO) and TiO 2 nanotubes (NTs) is reported. Electrochemically derived TiO 2 nanotubes were covered partially by RGO matrix in the form of distributed islands, on top of which Pd nanoparticles were dispersed uniformly. After detailed structural and morphological characterizations, gas sensing potentiality of the developed ternary hybrid device was tested for detection of methanol vapor and the sensing performance was compared with that of the RGO-TiO 2 binary structure to ensure the improvement caused by incorporation of the ternary element (Pd). Underlying mechanistic framework for gas sensing, by such ternary junction, was explained with the help of corresponding energy band diagram.

Black phosphorus nanosheets (BP NSs)-decorated single-layer WS2 phototransistors were fabricated by drop-casting the liquid-phase exfoliated BP NSs atop the channel of single-layer WS2 grown by chemical vapor deposition technique. It was found that, upon the decoration of BP NSs, the BP/WS2 hybrid phototransistor exhibited an enhancement of responsivity and extension of response spectral range. The responsivity is up to 120 mA/W in the hybrid phototransistor, being about 20 times larger than that in devices based on the pristine single-layer WS2. Moreover, the hybrid device possess high response speed with the response and recovery time of ~54 and ~140 μs, respectively, and also excellent photoswitching stability.

Solution-processed quantum dots (QDs) have a high potential for fabricating low cost, flexible and large-scale solar energy harvesting devices. It has recently been demonstrated that hybrid devices employing a single monovalent cation perovskite solution for PbS QD surface passivation exhibit enhanced photovoltaic performance when compared to standard ligand passivation. Herein we demonstrate that the use of a triple cation Cs0.05(MA0.17FA0.83)0.95Pb(I0.9Br0.1)3 perovskite composition for surface passivation of the quantum dots results in highly efficient solar cells, which maintain 96 % of their initial performance after 1200h shelf storage. We confirm perovskite shell formation around the PbS nanocrystals by a range of spectroscopic techniques as well as high-resolution transmission electron microscopy. We find that the triple cation shell results in a favorable energetic alignment to the core of the dot, resulting in reduced recombination due to charge confinement without limiting transport in the active layer. Consequently, photovoltaic devices fabricated via a single-step film deposition reached a maximum AM1.5G power conversion efficiency of 11.3 % surpassing most previous reports of PbS solar cells employing perovskite passivation.

Until now, scissors, clips and electrocautery have been used to harvest the gastroepiploic artery (GEA) for grafting. Because this artery has many branches and large fragile satellite veins tangled around it, conventional methods are not suitable for quick harvesting without bleeding. In order to harvest the GEA easily and efficiently, a skeletonized technique using an ultrasonic scalpel was developed, but the blade of this device was not well designed for fine tissue dissection. In order to address this problem, we have developed an alternative harvesting technique using a hybrid bipolar/ultrasonic energy device. This hybrid device integrates both electrical bipolar energy and ultrasonic frictional heat energy and is thus more versatile than traditional energy devices. In addition, it achieves faster dissection speed while offering similar bursting pressure and acceptable thermal spread. Finally, our device has an improved blade design that is suitable for fine tissue dissection. This video tutorial demonstrates our use of this new hybrid energy device and shows how it enables the surgeon to harvest the GEA quickly, safely, with little bleeding, and with less instrument exchange.

This paper addresses the potential benefits of multimodal haptic feedback combining vibrotactile and impact stimuli for the target domain of virtual collision simulation. In this hybrid approach, we complement the limitation of each modality with the advantage of the other modality. We present the design of a hybrid device including both vibration and impact actuators and a physics-based rendering method for realistic collision simulation. We also report a user study carried out to comparatively assess the subjective quality of haptic collision rendering using vibration only, impact only, and multimodal (vibration + impact) stimuli. Experimental results demonstrate that our multimodal approach can contribute to critically expanding the dynamic range of virtual collision simulation, especially between highly stiff objects.

We demonstrate ultra-thin ALD-processed dual-oxide (Al 2 O 3 /TiO 2 ) hybrid device with memory and selector characteristics by engineering the stability of metal filament in Al 2 O 3 and TiO 2 layer. The optimized hybrid memory device shows outstanding performances such as low off current $( , low reset current $( , and high on/off ratio $(> 10^{4})$ . Inserting a Ti buffer layer which has a low electrode potential value, we observed excellent uniformity and retention property. Finally, an outstanding read/write margins and ultra-low power consumption are confirmed through array simulations of the proposed hybrid memory device.

The hybrid device 2.0 is intended to monitor the moisture level of walls, however, due to the universality of the measurement method, it can also be used in the case of objects with different electrical properties. As the name suggests, the hybrid tomograph has the task of combining two measuring methods (the EIT impedance measurement method and the ECT capacitance measurement method).

Graphene with excellent mechanical properties shows potential applications in flexible devices. By decorating graphene with ZnO nanoparticles, the response of graphene-based flexible light sensor to light was enhanced. The light sensor showed different response rates with light intensities under different wavelength which indicated that the as-designed sensor can be used to detect the wavelength and intensity of light simultaneously. The microstructures and photonic properties of the hybrid device revealed that the interface played an important role on the performance of device. This result confirmed the method to prepare graphene/ZnO hybrid light sensor are convenient and economical, which may be applied in wearable devices.

Made available in DSpace on 2018-12-11T16:44:09Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-12-01 The symmetrical dual-k spacer technology in hybrid FinFETs has been widely explored for better electrostatic control of the fin-based devices in nanoscale region. Since, high-k tangible spacer materials are broadly became a matter of study due to their better immunity to the short channel effects (SCEs) in nano devices. However, the only cause that restricts the circuit designers from using high-k spacer is the unreasonable increasing fringing capacitances. This work quantitatively analyzed the benefits and drawbacks of considering two different dielectric spacer materials symmetrically in either sides of the channel for the hybrid device. From the demonstrated results, the inclusion of high-k spacer predicts an effective reduction in off-state leakage along with an improvement in drive current. However, these devices have paid the cost in terms of a high total gate-to-gate capacitance (Cgg) that consequently results poor cutoff frequency (fT) and delay.

The purpose of this study was to evaluate an alleged EEG amplifier’s, the Freer Logic BodyWave, ability to record EEG by comparing its signals to those recorded at the same time by a proven EEG amplifier, the Emotiv EPOC+. The BodyWave’s circuitry is similar to that of an Electro-dermal Activity meter and alleges to record surface-EEG from a limb of the user. The EPOC+ has been proven in previous studies to record signals of high-enough quality to be used in research, whilst the BodyWave is unproven. In order to compare their recordings, both EEGs were worn simultaneously whilst different stimuli induced various brain states. 15 participants were recruited and each subjected to two different experimental paradigms meant to induce increased attention and increased relaxation. Both headsets achieved a classification accuracy well above chance when differentiating between the attention and relaxation tasks. Further testing provided evidence that data from the alpha and beta frequency bands was contributing the most to the classifier’s accuracy. However the total lack of correlation between the signals of the two devices strongly implies that the BodyWave is not measuring EEG. Despite this these results show that in some cases it can be used in place of an EEG to perform a similar function. It also proved to be much more robust against muscle artefacts compared to the EPOC+.

Electrode design is of significant importance in the construction of enhanced electrochemical performance, and nanoarray is an attractive architecture for energy storage devices with a large specific surface area. Herein, we report the development of binary FeCo2O4@NiCo2S4 array tubes on Ni foam (Ni@FeCo2O4@NiCo2S4) as an efficient non-noble-metal electrode material for battery-supercapacitor hybrid device in alkaline electrolytes. Meanwhile, the unique 3D structure provides a desirable large electroactive area and rapid electron conductivity, resulting in remarkable electrochemical behavior in terms of high specific capacity (5.99 W cm−2 with a 260 mWh cm−2 of energy density for Ni@FeCo2O4@NiCo2S4). The long-term cycling stability of 76.9% capacity retention after 5000 cycles at 50 mA cm−2 for Ni@FeCo2O4@NiCo2S4 could be obtained. These results demonstrate that the fabricated high-performance electrode materials can be a promising candidate for battery-supercapacitor hybrid devices.

Single basin solar still (SBSS) has low productivity in this experimental research, some techniques have been employed to solve this problem, these techniques consist of using a flat plate collector. The main aim of this research was to make efficient use of the flat plate collector (FPC) to increase solar still productivity, and it works as a hybrid device. The model solar water heater for the flat plat collector (FPC) was coupled with a solar still, and the tests were repeated in 3 to 5 winter days, and the results were measured in the same way for each day. The results revealed that the productivity of the still increased 87 % when coupled with one, and decreased 20 % and 50 % when coupled with two and three flat plate collectors in southern Algeria, respectively.

The demand for seafood is continually increasing. The best way to meet that is through the aquaculture. In Malaysia, the important alternative source of fish supply is the fish-farms. Nowadays, fish-farms use unclean and expensive energy, which cannot meet the environmental and climate goals. This paper presents a hybrid device consisting of two Low-Speed Vertical Axis Current Turbines (LS-VACTs), generators, batteries, controller and solar-panels. This device is used as a hybrid solution because of the lake of electricity, low water/marine current speed surrounding the fish-farms and variable nature of both resources solar and marine-currents. This device has lower cabling and infrastructure requirements and reduced capital costs. This paper investigates the performance of the hybrid system and predicting power take-off and the number of solar panels required to provide sufficient energy for fish-farm using MATLAB-Simulink environment. The experimental results of LS-VACT show that the turbine has a power coefficient (CP) = 19.4% and high torque coefficient of 0.76 at a speed of 1 m/s. The simulation results indicate that the power output of the system can provide 20 kWh/day with water/marine current speed higher than 1 m/s. This combination of both resources can sustain and produce enough power for electrification of fish-farm.

Plasmonic and nanopore sensors have separately received much attention for achieving single-molecule precision. A plasmonic "hotspot" confines and enhances optical excitation at the nanometer length scale sufficient to optically detect surface-analyte interactions. A nanopore biosensor actively funnels and threads analytes through a molecular-scale aperture, wherein they are interrogated by electrical or optical means. Recently, solid-state plasmonic and nanopore structures have been integrated within monolithic devices that address fundamental challenges in each of the individual sensing methods and offer complimentary improvements in overall single-molecule sensitivity, detection rates, dwell time and scalability. Here, the physical phenomena and sensing principles of plasmonic and nanopore sensing are summarized to highlight the novel complementarity in dovetailing these techniques for vastly improved single-molecule sensing. A literature review of recent plasmonic nanopore devices is then presented to delineate methods for solid-state fabrication of a range of hybrid device formats, evaluate the progress and challenges in the detection of unlabeled and labeled analyte, and assess the impact and utility of localized plasmonic heating. Finally, future directions and applications inspired by the present state of the art are discussed.
