Manganese dioxide could make the preparation of micromotors increasingly cost-effective, opening up new avenues for their use, according to a new study from the University of Eastern Finland.

I was fascinated by the idea of jet packs when I was a kid. They were sci-fi magic, and the idea that you could strap into an oversized backpack wrapped in tinfoil and fly around was very enticing.

OIST researchers developed simple catalysts based on Earth-abundant manganese to use carbon dioxide for energy storage or turn it into useful chemicals for the industry. Carbon dioxide (CO2) is known ...

Manganese dioxide could make the preparation of micromotors increasingly cost-effective, opening up new avenues for their use, according to a new study from the University of Eastern Finland.

In their experiments, the researchers built aqueous zinc-manganese dioxide cells and tested them over 100 cycles. They discharged and attempted to recharge the batteries in experiments while using ...

Acceleration of the chemical reaction by β-MnO2 catalyst in the nanospace of the particles. (Image: Keiko Kamata, Tokyo Institute of Technology) Materials engineering has advanced to a point at which ...

A catalyst is a substance that speeds up a chemical reaction. The catalyst is not used up or chemically changed during the reaction. Enzymes are catalysts that work inside the cells of living ...

Some people collect stamps, some collect coins, some even collect barbed wire. But the aptly named [Plutonium Bunny] is an element collector, as in one who seeks a sample of as many elements on the ...

US researchers have stretched the operating life of aqueous zinc-manganese oxide batteries to over 5,000 cycles. The result is a rechargeable battery that cost only as much as a car battery but store ...
