Metal-free carbon catalysts (MFCCs) are one of the commonly used catalysts for electrocatalytic two-electron oxygen reduction (2e– ORR) synthesis of hydrogen peroxide (H2O2). Oxygen doping is an ...

Key messages - We found limited evidence of poor quality for using blood collected from a vein to detect altered levels of oxygen, carbon dioxide, and acidity in patients with respiratory failure.

What if a machine could suck up carbon dioxide from the atmosphere, run it through a series of chemical reactions, and essentially spit out industrially useful plastic?
