Single Atom Catalyst for Nitrate‐to‐Ammonia Electrochemistry

Small
Abstract Various life forms suffer from the negative effects of nitrate when it accumulates in water bodies, which is a major concern in the present day. The removal of nitrate from water bodies is a critical challenge, and the most effective method to achieve that is to change it into ammonia.

High-entropy alloyed single-atom Pt for methanol oxidation electrocatalysis

Nature Communications
The methanol oxidation reaction is the bottleneck for direct methanol fuel cells. Unfortunately, the state-of-the-art Pt-based catalysts suffer heavily from the CO poisoning problem. Isolating Pt atoms in a material can avoid CO poisoning.

Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams

Advanced Functional Materials, EarlyView.
A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.
