Traditional Li–S battery catalysts (e.g., pure CoSe 2) struggle to balance two key needs: strong LiPS adsorption (to suppress shuttling) and fast conversion kinetics (to boost capacity). Vacancy ...

Connecting a trifluoromethyl group to an organic compound through a heteroatom such as nitrogen, oxygen, or sulfur can help chemists get the properties they want when designing small-molecule drugs or ...

Heterocycles, molecular rings found in many pharmaceuticals, have a reputation for stubbornly resisting modification. That is, in a heterocycle, heteroatoms of one type aren’t easily swapped for ...

This research is led by Hui Xu (Huzhou Key Laboratory of Green Energy Materials and Battery Cascade Utilization, School of Intelligent Manufacturing, Huzhou College, Huzhou, China) and Hua Wang ...

Nina Notman meets the chemists expanding the toolbox of reactions capable of adding, deleting and switching single atoms in rings at the heart of organic molecules The majority of small molecule drugs ...

Metal-N-doped carbon is a promising replacement for non-precious-metal catalysts such as Pt for the oxygen reduction reaction (ORR) in polymer electrolyte membrane fuel cells (PEMFCs). Although these ...

A reaction that kicks out a single nitrogen, oxygen or sulfur atom from six-membered rings using only blue light has been developed by US scientists. The method involves breaking the C–N, C–O or C–S ...

1,3-Diphenyl-2-thiourea (DPTU) and 1-phenyl-3-(2-pyridyl)-2-thiourea (PPTU) were selected as the researched subject for investigating the effect of heteroatoms on the low carbon steel corrosion ...

ABSTRACT: A comprehensive mathematical model is developed to simulate the interactions of the complex processes that take place in typical catalytic chemical reactors. This mathematical model includes ...
