German and US scientists recently reported an unusual feat: they observed the world's fastest chemical reaction, during which hydrogen atoms bind onto and then leave a sheet of graphene, all within ...

Carboxylic acids are ubiquitous in bioactive organic molecules and readily available chemical building blocks. Carboxylic ...

A fuel cell stack, or bank, serves as the ‘engine,’ where many cells facilitate a simple chemical reaction between oxygen from the air and the pressurized hydrogen fuel stored onboard the vehicle.

For example, in liver cells the toxic chemical hydrogen peroxide must be broken down into the harmless products, water and oxygen. If this reaction happens too slowly then hydrogen peroxide can ...

The ORR is the chemical reaction in the process that converts hydrogen and oxygen into water and electricity in a fuel cell. The researchers said this particular chemical reaction limits the ...

This technology produces hydrogen at low voltage by substituting the water oxidation reaction (OER) with various chemical oxidation reactions, such as ammonia, alcohol, urea, and hydrazine.

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.
