The development of earth-abundant oxygen evolution reaction (OER) electrocatalysts with high activity and durability is critical for replacing noble-metal-based catalysts in the applications of scalable water electrolysis. A freestanding electrode architecture offers significant advantages over conventional coated powder forms due to enhanced kinetics and stability. However, precise control over electrode composition and the construction of uniformly distributed active sites within these electrodes remain challenging.

Background/purpose: Titanium dioxide nanotube (TNT) structures have been shown to enhance the early osseointegration of dental implants. Nevertheless, the optimal nanotube diameter for promoting osteogenesis remains unclear due to variations in cell types and manufacture of nanotubes. This study aimed to evaluate the differences in MC3T3-E1 and Saos-2 cells behavior on nanotubes of varying diameters.

In recent years, luminescent solar concentrators (LSCs) have gained a renaissance as a pivotal transparent photovoltaic (PV) for building-integrated photovoltaics (BIPVs). However, most of the studies focused on light-selective LSCs, and less attention was paid to the utilization of the full solar spectrum. In this study, a lead-free microcrystal CsAgNaBiInCl (CANBIC) perovskite phosphor is demonstrated to have bifunctional effects of luminescent down-shifting (LDS) and light scattering for the fabrication of LSCs, realizing light response from ultraviolet (UV) to NIR regions by an edge-mounted Si solar cell.

Green and biowaste, processed within large facilities into compost, is a key fertilizer for agricultural and horticultural soils. However, due to improper waste disposal of plastic, its residues often remain or even lead to the formation ofmicroplastics (1 µm - 5 mm, MiPs) in the final compost product. To better understand the processes, we first quantified 'macroplastics' (> 20 mm, MaPs) input via biowaste collection into an industrial composting plant, and, then determined MiP concentrations at five stages during the composting process (before and after shredding and screening processes), and in the water used for irrigation.

Hempseed oil (HSO) is extremely rich in unsaturated fatty acids, especially linoleic (18:2 n-6) and α-linolenic (18:3 n-3) acids, which determine its high sensitivity to oxidative and photo-oxidative degradations that can lead to rancidity despite the presence of antioxidant compounds. The aim of this work was to evaluate which material/temperature/light solutions better preserve HSO quality during its shelf life and to test NIR as a rapid, non-destructive technique for monitoring oxidation phenomena. Futura 75 hemp seeds were cold-pressed; the oil was packed into 20 mL vials of four different materials (polypropylene, clear glass, amber glass, and amber glass coated with aluminum foil) and stored for 270 days at 25 °C under diffused light and at 10 °C in dark conditions.
