Robust isolated quantum spins established on a magnetic substrate

Establishing robust isolated spins on solid surfaces is crucial for fabricating quantum bits or qubits, sensors, and single-atom catalysts. An isolated spin is a single spin that is shielded from external interactions. Because ...

Atomic-scale copper arrangements steer reactions to produce hydrogen or methane

Scientists have discovered a way to control chemical reactions by carefully arranging copper atoms on a carbon-based material. With just tiny changes at the atomic scale, the same material can be switched to produce either ...

Single quantum device that measures amperes, volts and ohms could revolutionize how we measure electricity

A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical potential) and the ohm ...

Industry managed forests more likely to fuel megafires, study finds

The odds of high-severity wildfire were nearly one-and-a-half times higher on industrial private land than on publicly owned forests, a new study found. Forests managed by timber companies were more likely to exhibit the ...

Q&A: Wildfire char shows promise for reducing atmospheric methane emissions

It's hard to believe that there is anything positive that could come out of wildfires. They have devastated homes, taken lives, erased memories, leveled cities and destroyed our forests and wildlands. But a University of ...
