The dichromate ion, Cr₂O₇²⁻, is a vibrant orange-colored chemical species often encountered in redox reactions. Understanding its behavior hinges on determining the oxidation number of chromium (Cr) ...

Viral videos sometimes show dramatic chemistry demonstrations but some combos are extremely dangerous. This video explains, at a high level, why oxidizers like potassium permanganate react violently ...

Biomolecular condensates formed by liquid-liquid phase separation (LLPS) establish gradients of biomolecules and ions across the dilute-dense interface, giving rise to interfacial electric fields ...

While hazardous at high concentrations, free radicals and radical-derived, nonradical reactive species in moderate concentrations play an important role as regulatory mediators in signaling processes.

Abstract: The Internet of Bio-Nano Things (IoBNT) is an emerging area of networking where seamless interconnection between biological and electrical nanotechnology-enabled devices is envisioned to ...

Rust, patina, fire, rancid food — they all have oxidation in common. So let’s take a look at exactly what that is. Life as we know it today couldn’t exist without oxygen. So, we’re lucky that there’s ...

I was very concerned by the article “Cloudy Outlook for Sunscreen Market” in the Nov. 28, 2022, issue of C&EN (page 13). The danger of skin cancer and the benefits of sunscreens in preventing skin ...

Antioxidant intervention is considered to inhibit reactive oxygen species (ROS) and alleviate hyperglycemia. Paradoxically, moderate exercise can produce ROS to improve diabetes. The exact redox ...
