Summary: In this work, nanostructured nickel thin films deposited on porous nickel foam substrate were studied for improved oxygen evolution reaction (OER) catalysis. The Ni@NF electrocatalyst showed outstanding OER properties, such as minimum overpotential and high current density. The impressive performance of the catalyst is attributed to the synergic effect generated between nanostructured-Ni and porous NF substrate, enhancing the electrical conductivity.

Summary: This study reported the preparation of (Mn,Co,Fe,Ni,Cr)3O4 high-entropy spinel oxide thin film with a thickness of -500 nm using a facile spray pyrolysis technique. The structural and electrical properties of the film were characterized after heat treatment at temperatures ranging from 400-900°C. The as-deposited film was amorphous and crystallized at 500°C, showing a homogeneous elemental distribution and the desired Fd-3m cubic spinel structure. The electrical conductivity of the film was found to depend on the processing temperature, with the highest conductivity obtained at 700°C.

Summary: Ammonia (NH3) production, storage, and transportation are susceptible to leaks, posing risks to the environment and human life. Detecting NH3 within the exposure limit is crucial for eliminating health hazards. Thin films of zinc ferrite (ZF) were deposited using spray pyrolysis at different substrate temperatures. The film deposited at 225 degrees C showed a good sensing response to 25 ppm of NH3 and exhibited stability over 90 days. This research demonstrates that ZF thin films can effectively detect NH3 in the environment.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
