Bioinspired enzyme model with a redox switch

Coupled oxygen transfer and electron transfer reactions that use cofactors are enzymatic reactions of crucial significance to all lifeforms from bacteria to vertebrates. In the European Journal of Inorganic Chemistry, scientists ...

Which came first: Complex life or high atmospheric oxygen?

We and all other animals wouldn't be here today if our planet didn't have a lot of oxygen in its atmosphere and oceans. But how crucial were high oxygen levels to the transition from simple, single-celled life forms to the ...

New catalytic effect discovered for producing gallium oxide

Semiconducting oxides are a new class of materials that are currently enjoying great attention in the field of semiconductor technology. Gallium oxide is the archetypal example for its ability to handle extremely high voltages ...

Spin current from heat—new material increases efficiency

Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents." ...

Supercomputing mimics berkelium experiments to validate new find

The Titan supercomputer at the Oak Ridge Leadership Computing Facility (OLCF) has enabled scientists to explore an unexpected oxidation state in the rare, radioactive element berkelium that was first observed in experiment. ...
