Advanced Science, EarlyView.Two NO‐containing iron units, biologically relevant as NO storage/release centers, connected by sulfur, display characteristics arising from multiple quantum levels in their extensively delocalized arrangement. Analysis in three charge levels finds the electron distribution almost substantially spread over all atoms of its composition: 2S, 2Fe, and 3NO.

Advanced Energy and Sustainability Research, EarlyView.This graphical abstract emphasizes the working principle and the various essential factors of the direct methanol fuel cell (DMFCs). Additionally, various parameters, such as the nanoparticle's size and shape, the nature of the electrolyte, the type of support materials, and their fabrication process, also play essential roles in the functioning of the

Advanced Energy and Sustainability Research, EarlyView.Three‐dimensional WO3 nanosheets (3D‐NS) with exposed {001} facets are grown in situ, forming a highly interconnected 3D architecture, which is sensitized with a polymeric perylene bisimide layer and test for HBr photooxidation. The self‐assembly of a quantasome architecture—based on perylene bisimide dyes, templated around a tetra‐ruthenated ...
