Article Synopsis
- The research focuses on discovering new high-entropy electrocatalysts through high-throughput screening of thin-film material libraries, which allows the testing of numerous compositions efficiently.
- The study confirms that results from these thin films can be effectively transferred to particulate catalysts, specifically demonstrating this with the Cantor alloy oxide (Co-Cr-Fe-Mn-Ni)O.
- The identified best-performing composition from the screening, (CrMnFeCoNi)O, showed successful synthesis in particle form and maintained similar effectiveness for the oxygen evolution reaction (OER), validating the approach for faster catalyst discovery.

Photosynthesis in deserts is challenging since it requires fast adaptation to rapid night-to-day changes, that is, from dawn's low light (LL) to extreme high light (HL) intensities during the daytime. To understand these adaptation mechanisms, we purified photosystem I (PSI) from Chlorella ohadii, a green alga that was isolated from a desert soil crust, and identified the essential functional and structural changes that enable the photosystem to perform photosynthesis under extreme high light conditions. The cryo-electron microscopy structures of PSI from cells grown under low light (PSI) and high light (PSI), obtained at 2.

Biosorption of Pb(II) on bael leaves (Aegle marmelos) was investigated for the removal of Pb(II) from aqueous solution using different doses of adsorbent, initial pH, and contact time. The maximum Pb loading capacity of the bael leaves was 104 mg g(-1) at 50 mg L(-1) initial Pb(II) concentration at pH 5.1.
