Introduction The oxygen-evolving complex, Mn 4 CaO 5, serves as the catalytic site for oxidizing two substrate water molecules and driving oxygen evolution in photosystem II (PSII). (1) This process ...

Lakes and reservoirs globally are experiencing unprecedented changes in land use and climate, depleting dissolved oxygen (DO) in the bottom waters (hypolimnia) of these ecosystems. Because DO is the ...

Boosting the selectivity in oxygen electrocatalysis using chiral nanoparticles as electron-spin filters In this study, chiral gold nanoparticles with a concave vortex cube structure were employed as ...

Life can use many other electron acceptors — like sulfate, nitrate and iron — but oxygen is the highest-energy acceptor available.

The film discusses the essential needs for survival—oxygen, food, and water—shared by humans and animals. It highlights how astronauts must bring these necessities when venturing into space ...

Award-winning news and culture, features breaking news, in-depth reporting and criticism on politics, science, food and entertainment.

Detailed molecular characterization of a constitutively active bacterial NADPH oxidase (NOX) provides clues to the activation mechanism required to trigger electron transfer and reactive oxygen ...

Researchers at the National University of Singapore (NUS) have created a microporous covalent organic framework with dense donor-acceptor lattices and tailored links for the clean and effective ...

Donor doping into a mother material with disordered intrinsic oxygen vacancies, instead of the widely used strategy of acceptor doping into a material without oxygen vacancies, can greatly enhance ...

Among them, the fused ring electron acceptors, such as ITIC, Y6, and their analogous have proved to be the most successful NFAs and have achieved efficiencies of over 19%.

The question was, "how are mitochondria capable of maintaining these electron inputs when oxygen is not the terminal electron acceptor?" Reporting in Science, researchers have found some answers. They ...
