Summary: This study focuses on the performance of different morphologies of zinc oxide nanoparticles in thiophene desulfurization. The results show that flower-like zinc oxide flakes exhibit the best performance in thiophene desulfurization. Moreover, all zinc oxide morphologies apply to pseudo-second-order models. The optimal conditions for thiophene desulfurization are pH 7, 0.05 g/L zinc oxide flakes loading, and 90 minutes of contact time.

Summary: ZnSe/ZnO heterostructures were synthesized using the microwave-assisted hydrothermal method with zinc acetate and zinc nitrate as the source of Zn2+ ions. The incorporation of ZnSe into the ZnO matrix resulted in changes in the size of ZnO crystallites and lattice parameters. Optical and texture analyses showed that ZnSe particles caused a decrease in gap energy and a significant increase in the specific surface area of ZnSe/ZnO heterostructures. ZnSe/ZnO heterostructures synthesized with zinc acetate exhibited better photocatalytic performance in visible light compared to pure ZnO.

Summary: This study presents an innovative method for fabricating inkjet-printed tracks using Zn nanoparticle ink and low-temperature in situ chemical sintering of curing ink. Chemical curing allows for the use of flexible substrates that cannot withstand traditional high thermal budgets. A specific acid concentration in the curing ink is found to be crucial in determining the electrical properties of the printed Zn nanoparticles, resulting in highly conductive and mechanically flexible features. Additionally, a touch sensor circuit utilizing all-Zn printed conductive tracks is demonstrated.

Summary: Due to the upcoming global energy crisis, the search for energy-saving materials has become more urgent. Mechanically induced luminescent materials have received considerable attention over the past two decades for their ability to convert waste into useful components, such as converting stress into light. This study introduces a strategy to improve mechanoluminescence (ML) of ZnO by embedding it in a ZnF2:Mn2+ matrix, which shows promising applications in various mechano-optics scenarios.

Summary: In this study, core/shell ZnO/TiO2 nanocomposite samples were prepared using the sol-gel method at different time spans. The sample prepared in the 15-minute time span (ZnTi15) exhibited the highest photocatalytic activity and charge carrier density, making it the optimal sample. The formation of a heterojunction at the ZnO/TiO2 interface could be attributed to the increased photocurrent density observed for the ZnTi15 sample.

Summary: Due to climate change and the need for renewable energy, scientists are considering the modification of solar cells. This study investigates the effects of photocatalytic and anti-reflective coatings on the efficiency and stability of solar cells. Single-layer and double-layer zinc oxide thin films were studied for their photocatalytic and optical properties. The findings show that the double-layer thin film with a mesoporous top layer had the best anti-reflection performance, reducing the reflection of the glass substrate by 2.05%.
