Summary: Metal oxides, particularly indium tin oxide (ITO), are promising candidates for thermoelectric materials due to their high chemical stabilities. In this study, nanoporous ITOs with large crystallite sizes were successfully prepared using indium chloride as a source of indium and colloidal silica nanoparticles as templates. The controlled pore structure significantly reduced thermal conductivity while maintaining electrical conductivity, showing the potential for independent control of these properties in thermoelectric materials.

Summary: Electrochemical reduction of CO2 to various chemicals is a promising approach, but challenges such as high overpotential, poor stability, and low selectivity remain. Multi-component materials, like indium-doped tin oxide nanowires (In-SnO2 NWs), have been proposed to overcome these problems. The unique 1D structure and In-doping of SnO2 NWs enhance formate selectivity by up to 82% compared to bare SnO2 NWs at -1.04 V (vs RHE) by inducing electron delocalization and providing more active sites for stable adsorption of intermediates.

Summary: The study reveals that the thermal conductivity of polycrystalline SnS2 film is lower, approximately half that of single-crystalline SnS2 film, mainly due to phonon scattering at grain boundaries. Two simulation approaches suggest that thermal transport across crystal grains leads to the reduction of thermal conductivity, therefore, the thermal conductivity of polycrystalline SnS2 film can be substantially reduced by tuning the grain size.

Summary: The plasma-assisted Vapor-Liquid-Solid technique was used to grow Silicon nanowires on different substrates coated with tin and indium. The impact of substrate surface energy on the morphology and structure of the nanowires was studied. The results show that the characteristics of the nanowires, such as density, diameter, and length, vary depending on the substrate and catalyst material. The crystalline grain size of the nanowires is influenced by the substrate nature and catalyst material.

Summary: As the working environment becomes more complex, there is an increasing demand for transparent and flexible electromagnetic interference (EMI) shielding films in electronic devices. This study proposes a multilayer structure strategy to fabricate transparent and flexible indium tin oxide (ITO)/silver nanowire (AgNW) composite films, which achieve high light transmission, strong EMI shielding, and good thermal insulation properties. The combination of excellent EMI shielding performance, outstanding near-infrared shielding performance, and high light transmittance makes the ITO/AgNW (IA) composite films promising for various applications.

Summary: This study investigated the electrical and thermal properties of copper nanowires (CuNWs), revealing that structural scattering is the predominant mechanism in the electrical current transport and heat transfer in the nanowires. The residual resistivity and electron-phonon coupling parameter were found to increase with the degree of structural scattering. High values of residual unified thermal resistivity and electron-phonon-induced unified thermal resistivity were also discovered in the CuNWs.

Summary: In this study, wavelength-thick indium tin oxide (ITO) films were successfully grown and characterized using high power impulse magnetron sputtering (HiPIMS) with post deposition processing. The films achieved an epsilon near zero (ENZ) property at 1550 nm telecom wavelengths. By consecutively annealing the ITO film, the plasma frequency gradually shifted, enabling fine tuning of the ENZ wavelength regime from 1800 to 1500 nm. The films were characterized using spectroscopic ellipsometry, transmission electron microscopy, x-ray diffraction, and energy dispersive x-ray spectroscopy. The findings of this study provide a method to control the ENZ property at the desired wavelength and reduce absorption loss for device applications.

Summary: In this study, a p-type nickel oxide foam/n-type tin-doped indium oxide nanowires composite was fabricated for ethylene glycol gas sensing, which showed a unique response to 100 ppm ethylene glycol at a low temperature of 125 degrees C, along with fast response/recovery time. The excellent gas-sensitive performance of the composite can be attributed to the formation of p/n heterojunctions and the In and Sn doping of NiO during ITO growth. This fabrication method provides an effective strategy for building NiO-based heterostructures for high-performance gas sensors.

Summary: This study investigates the influence of antimony (Sb) species on the electrical properties of Sb-doped zinc oxide (SZO) thin films. The Sb species-related defects were controlled by changing the Sb2O3 content in the ablating target. Increasing the Sb2O3 content led to the dominance of Sb3+ species and a conversion from n-type to p-type conductivity in the SZO films. The substituted Sb species and Sb-Zn complex defects were responsible for the different conductivity types at low and high-level doping.

Summary: In this study, researchers reported a highly sensitive and selective NO2 sensor fabricated through low-cost and scalable methods using a hybrid nanocomposite of two-dimensional Al70Co10Fe5Ni10Cu5 quasicrystal (QC) nanosheets and MoS2 nanoflakes. The Al70Co10Fe5Ni10Cu5/MoS2 heterostructure showed an excellent gas-sensing response of about 66%, which is 2.27 times higher than that of the pristine MoS2 nanoflakes-based sensor. The integration of the 2D Al70Co10Fe5Ni10Cu5 QC with MoS2 nanoflakes holds great promise in the design and development of NO2-based gas-sensing technology.

Summary: Through investigating the electrical properties and x-ray detection performance of CdSe single crystals grown by the pressure-assisted vertical Bridgman method, it was found that the enhanced trapping-detrapping effect at liquid nitrogen temperature significantly improved the x-ray photocurrent and response time. The mobility-lifetime product of CdSe single crystals also increased from 1.39 x 10(-5) to 5.34 x 10(-4) cm(2) V-1 with temperature lowering. Furthermore, CdSe single crystal-based x-ray detectors demonstrated ultrahigh sensitivity and extremely low detection limit at liquid nitrogen temperature, making them a promising candidate for x-ray detection applications.

Summary: We improved the sensitivity of NO2 analyte by adjusting the width ratio of adjacent graphene oxide (GO) and reduced graphene oxide (rGO) layers using GO laser reduction technique. The reduction of GO led to a chemiresistive response to NO2, and an optimum GO/rGO width ratio achieved a chemiresistive response of 18.1% towards 100 ppm of NO2 with a limit of detection of 230 ppb. The enhanced chemiresistive response of GO/rGO sensors to NO2 physisorption was attributed to increased sorption energy and improved charge transfer at the GO/rGO interface area compared to fully reduced GO.
