Influence of defects on the enhancement of thermoelectric properties in Sn-doped ZnO nanostructure synthesized via hydrothermal route.

The efficiency of materials' thermoelectric properties is often limited by various factors, and enhancing these properties through defect engineering is an effective strategy. This study investigated the defects-induced thermoelectric characteristics of Sn-doped ZnO nanoparticles. The samples were synthesized using the hydrothermal technique with varying concentrations of Sn.

Synergistic integration of VSe and CuS nanostructures for advanced energy storage applications.

The demand for sustainable energy storage has driven advancements in supercapacitors, known for their high-power density and rapid charge cycles. However, challenges like limited energy density and material stability must be addressed for practical applications. In this study, VSe/CuS nanocomposites were synthesized using a simple wet chemical method and investigated as electrode materials for supercapacitors.

Design of ZnO-VSe nanocomposite for high performance asymmetric supercapacitors.

Supercapacitors exhibit limitations such as low energy density, high self-discharge rates, and degradation of electrochemical performance over extended cycling. This study presents the development of a high-performance asymmetric supercapacitor by synthesizing novel ZnO-VSe nanocomposites through wet-chemical methods, aiming to enhance capacity, energy density, and durability. The capacitive performance of these materials was systematically evaluated in an aqueous alkaline electrolyte (KOH) at a concentration of 2 M.
