Summary: A series of glasses in the ZnO-MoO3-TeO2 system were synthesized and investigated for their thermal, optical, structural, and electrical properties. Substitution of TeO2 for ZnO and/or MoO3 resulted in structural transformation and decomposition of the tellurite network. The major charge transport mechanism in these glasses is the polaronic process through the tellurite glass network. Molybdenum oxide positively affects the electrical conductivity of the glasses, while Zn2+ ions limit free electron transport. These glasses with wide optical transmittance and relatively high electrical conductivity may find application in optoelectronic devices.

Summary: Four different ZnO nanostructures, including nanoparticles, nanorods, nanoribbons, and nanoshuttles, were synthesized by controlling pH levels, chemical compositions, and process conditions. The properties of these nanostructures, such as structure, wettability, optics, and electrical conductivity, depend on their morphology and particle size. ZnO nanoparticles are hydrophilic, while other nanostructures are hydrophobic. Moreover, ZnO nanorods exhibit higher electrical conductivity compared to other nanostructures, whereas ZnO nanoshuttles have the lowest electrical conductivity. Grain boundaries and semiconducting nature play a role in influencing the electrical conductivity of ZnO nanostructures.

Summary: Calcium doped zinc oxide ceramics were synthesized using the solid state reaction method. The phase, band gap, and negative temperature co-efficient of resistance (NTCR) properties were determined through various techniques. Doping with calcium decreased the dielectric constant of ZnO, while the Ca doped sample exhibited a significant decrease in dielectric constant. The impedance study revealed NTCR behavior and a temperature dependence of electrical relaxation phenomena at higher temperatures. The band gap of ZnO decreased and the Urbach energy increased with doping.

Summary: The study reveals that the glass stability of tellurite glasses decreases with increasing Bi2O3 content, attributed to the decomposition of TeO4 units, replacement of Te-O-Te bonds by Te-O-Bi bonds, and formation of Bi-O-Bi bonds. Additionally, an increase in Bi2O3 content resulted in a decrease in the optical band gap, indicating glasses with high polarizability suitable for optical and photonic applications.

Summary: In this study, a facile electrospinning method was used to fabricate nanofibrous tin oxide electrodes with different annealing temperatures, which showed potential in high-performance energy storage applications. The tin oxide processed at 400 degrees C exhibited excellent specific capacitance (844 F/g) and interfacial capacitance (0.1434 F/cm(2)) at 1 mV/s scan rate in 1 M NaOH aqueous electrolyte, and demonstrated remarkable stability even after 2000 cycles. The electrodes were confirmed to have a morphology with beads formation through scanning electron microscopy, and the hydrophilic nature of the electrode surface was confirmed by water contact angle measurements. Structural analysis was conducted using X-ray diffraction (XRD), Raman spectroscopy, Energy dispersive X-ray analysis (EDAX), and X-ray photoelectron spectroscopy (XPS). Furthermore, the flexible symmetric supercapacitor device showed excellent flexibility and electrochemical stability during mechanical bending up to 180 degrees, suggesting that SnO2 is a promising electrode material for future flexible and wearable electronics devices.

Summary: Experimental work was conducted to enhance the properties of ambient pressure dried silica aerogels for thermal insulation applications. The quality of the aerogels produced was determined by the sol-gel method and silylating agent used. A two-step sol-gel method was employed to synthesize sodium silicate-based aerogels, with silylation carried out using trimethylchlorosilane (TMCS). The aerogels prepared using 33.3% TMCS exhibited desirable characteristics such as narrow pore size distribution, homogenous tiny particles, improved visual optical transmission, low density, low thermal conductivity, high specific heat capacity, high porosity, high surface area, and stable hydrophobicity up to 445°C. The thermal insulating property of these aerogels was confirmed in the laboratory, demonstrating their suitability for thermal insulation.
