Unraveling the pH-dependent oxygen reduction performance on single-atom catalysts
Feb 21, 2024 (Nanowerk News) Metal-nitrogen-carbon (M-N-C) single-atom catalysts are a promising type of catalyst that could help provide cost-effective alternatives to platinum-based ones. However, there are still some aspects of their behavior that are misunderstood. To rectify this, a group of researchers delved into the intricacies of M-N-C catalysts,...
Looking deep into smallest pores
Feb 21, 2024 (Nanowerk News) Membranes of vertically aligned carbon nanotubes (VaCNT) can be used to clean or desalinate water at high flow rate and low pressure. Recently, researchers of Karlsruhe Institute of Technology (KIT) and partners carried out steroid hormone adsorption experiments to study the interplay of forces in...
New non-toxic method for producing high-quality graphene oxide
Feb 20, 2024 (Nanowerk News) Graphene oxide is often used to produce graphene by removing oxygen. However, if you have holes in graphene oxide, you have holes also after converting it into graphene. Therefore, the quality of the graphene oxide is very important. Alexandr Talyzin and his research group at...

The Radcliffe Wave is waving
Feb 20, 2024 (Nanowerk News) A few years ago, astronomers uncovered one of the Milky Way’s greatest secrets: an enormous, wave-shaped chain of gaseous clouds in our sun’s backyard, giving birth to clusters of stars along the spiral arm of the galaxy we call home. Naming this astonishing new structure...
Plastic recycling with a protein anchor
Feb 20, 2024 (Nanowerk News) Polystyrene is a widespread plastic that is essentially not recyclable when mixed with other materials and is not biodegradable. In the journal Angewandte Chemie ("Engineered Anchor Peptide LCI with a Cobalt Cofactor Enhances Oxidation Efficiency of Polystyrene Microparticles"), a German research team has introduced a...
