Summary: Cobalt (Co)-doped ZnO nanoparticles were synthesized at 100°C using a simple chemical technique, resulting in nanoparticles with high crystallinity and reduced defect density. Co-doping suppressed oxygen-vacancy-related defects at lower doping densities, but increased defect density at higher doping densities. Co-doping was found to significantly suppress defects in ZnO for electronic and optoelectronic applications, as demonstrated by XPS, PL, electrical conductivity, and Mott-Schottky analysis. Photodetectors fabricated with Co-doped ZnO nanoparticles showed faster response time due to the reduced defect density.

Summary: We measured the movement of intrinsic point defects in ZnO nano- and micro-wires driven by electric fields and observed their impact on the electrical properties of the wires. The results explain the instability in nanowire transport and demonstrate a new method for refining and processing ZnO nanowires. These findings highlight the importance of in-operando intrinsic point-defect migration during nanoscale electric field measurements.

Summary: The crystal structure and electrical properties of Bi3GaSb2O11 at high temperatures were investigated. No phase transitions or change in oxygen content were observed in air at temperatures ranging from 26 to 800 degrees C. The crystal structure was refined using neutron diffraction data, and different types of bonds with varying thermal expansion coefficients were identified. The electrical conductivity of Bi3GaSb2O11 was found to be influenced by both electron conduction and oxide-ion conduction, depending on the gas atmosphere.

Summary: The properties of zinc oxide nanoparticles prepared by the solution precursor plasma spray (SPPS) technique were investigated. The crystalline structure was found to be hexagonal wurtzite with no secondary phase. The band gap of ZnO increased with higher concentration of the feedstock solution. The size and spherical shape of the nanoparticles were confirmed by microscopy. The electrical conductivity and dielectric constant of the ZnO powder were affected by the initial mole concentration.

Summary: The recent stuck of development of kesterite based photo-voltaic devices is partly due to issues with open circuit voltage, particularly in Cu and Zn containing kesterite compounds. Lattice disorder connected to these cations is considered an important factor, affecting the structural, optical and vibrational properties of the materials. However, detailed investigations on the role of disorder in the electrical properties of kesterite materials are still lacking.

Summary: This article discusses the development of a z-type thermoelectric element with a direct electrical junction based on dissimilar oxide conductors, Ca0.9Bi0.1MnO3 (n-type) and Ca2.7Bi0.3Co4O9 (p-type). A thermoelectric z-element was fabricated using hydrostatic pressing and an interconnector based on an oxide composite and silver particles. The microstructure of the thermoelectric legs was studied using electron microscopy. Measurements of resistivity and Seebeck coefficient were conducted, and the estimated power factor was calculated for different ceramic samples. The maximum output power of the manufactured thermoelectric module reached 1.1 mW at a temperature gradient of 580 degrees C and a cold side temperature of 37 degrees C. Additionally, simulations were performed to determine the resistance of interfaces between the thermoelectric material and interconnector. The study highlights the potential of hydrostatic pressing in producing complex-shaped thermoelectric elements without vulnerable metal-semiconductor electrical connections in oxide thermoelectric modules.

Summary: The diffusion and aggregation of oxygen vacancies in perovskites play important roles in material properties, and their impacts can be revealed by lowering the ferroelectric transition temperature with the introduction of oxygen vacancies in barium titanate. The anelastic relaxation processes due to oxygen vacancies may be partially hidden by the ferroelectric transition in perovskites, but can be uncovered by manipulating the material composition.

Summary: This study investigated the combination of WO3 sensing elements with a non-noble metal-carbon composite (Ni@rGO), showing improved gas responses for NO2, acetone, and CO. The addition of 0.35 wt % Ni@rGO composite to WO3 resulted in significantly increased sensory response for NO2 vapors and different responses for different concentrations of acetone. The response and recovery times for 0.35 wt % Ni@rGO/WO3 composite and CO gas were also determined.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.

Summary: This study focuses on the corrosion characteristics of AA 7075 and AA 7075 based hybrid composite fabricated using stir casting and hot rolling techniques. The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
