Lasers cause magnets to behave like liquids

Credit: CC0 Public Domain For years, researchers have been following a strange phenomenon: when you hit an ultrathin magnet with a laser, the magnetism suddenly becomes demagnetized. Imagine the magnet on your fridge. Now, CU Boulder scientists are studying how magnets recover from this change and regain their properties within a fraction of a second. According to a study published …

How do very small particles behave at very high temperatures?

The two alternative architectures of the gold nanoclusters contain 561 atoms. Credit: Swansea University An expert on nanomaterials at Swansea University has studied how small gold particles survive at very high temperatures. For some nanotechnology applications, such as in catalysis and aerospace, where nanometer dimensions are exposed to very high temperatures, research is of importance to mechanical engineering. The Study …
