Some of the potential applications of nanotechnology, for example in catalysis and aerospace, may subject particles of only nanometre dimensions to very high temperatures. How well will they survive the experience?
Scientists have managed to control atomically thin magnets with an electric field, a breakthrough that provides a blueprint for producing exceptionally powerful and efficient data storage in computer chips, among other applications.
Researchers show how a thin, elastic metasurface could reflect an incoming soundwave?s fundamental frequency as its second harmonic. This new material concept could enhance noise control in performances, city soundscapes and submarines.
