A strategy for the spin-acoustic control of silicon vacancies in a 4H silicon carbide-based bulk acoustic resonator

Bulk acoustic resonators—stacked material structures inside which acoustic waves resonate—can be used to amplify sounds or filter out undesired noise. These resonators have found wide use in today's RF telecommunication, ...

Superconductivity at room temperature remains elusive a century after Nobel Prize for landmark discovery

On April 8, 1911, Dutch physicist Heike Kamerlingh Onnes scribbled in pencil an almost unintelligible note into a kitchen notebook: "near enough null."

A graphene addition for enhancing the critical current density of Bi-2223 superconductors

Superconductors are materials that offer zero electric resistance to the flow of current on being cooled down below a certain critical temperature. Typically, superconductors have a very low critical temperature, close to ...

Scientists compare humans and chimpanzees to uncover evolution of language-relevant brain areas

Language is one aspect that makes us human. Other animals can learn words or calls and communicate, but the ability to generate an infinite number of utterances based on a small number of syntactic rules is unique to humans.
