Summary: Titanium-titania nanostructured electrodes were used to photoelectrochemically oxidize Am(III) to Am(VI) in 0.1 M HNO3 solutions under UV-light illumination. The oxidation process occurred through the generation of adsorbed hydroxyl radicals or direct electron transfer. The one-electron Am(VI/V) couple at 1.60 V vs SCE can be applied in nuclear fuel reprocessing, with Am being the main challenge.

Summary: A new strategy has been developed to incorporate Sn(II) cations into the structure of a photocatalytic oxide, Ba5Nb4O15, by leveraging the asymmetric coordination environments. This strategy enables the reduction of the band gap and the enhancement of photocatalytic activity under visible light by introducing Sn(II) cations. The study demonstrates the powerful utility of low-temperature Sn(II)-exchange reactions to sensitize layer-type oxide photocatalysts to the visible region of the solar spectrum.

Summary: This study investigates the characteristics of thin hole transport layers (HTLs) in vacuum-deposited perovskite solar cells. It is found that only very thin HTLs (<5 nm) result in high-performing devices, while thicker films (>= 5 nm) exhibit dynamic behavior in consecutive electrical measurements. Furthermore, small-molecule HTLs are found to lead to thermally unstable solar cells, possibly due to chemical reactions/diffusion at the interface with the perovskite layer.

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.
