Enhanced Nitric Oxide Electroreduction to Ammonia via Modulating Spin‐Polarization of Fe Single‐Atom Catalysts

Advanced Functional Materials, EarlyView.
A strategic spin‐polarization suppression in Fe single‐atom catalysts is proposed to enhance electrocatalytic reduction of NO to NH3. Employing a top‐down electrospinning strategy, self‐supported FeSAC with Fe‐N3S1 coordination structure and spin‐state transition is engineered from high‐spin to low‐spin.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

Advanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...
