Science Alert  July 9, 2021 An international team of researchers (USA – UC Berkeley, China) used tungsten needle in a ultracold chamber around -50 deg C into which water vapor was released and applied an electric field. Water molecules were attracted to the tip of the needle, where they crystallized, forming a microfiber with a maximum width of around 10 micrometers. When the temperature was lowered to between minus 70 and minus150 degrees Celsius they were able to bend. At minus 150 degrees Celsius, the microfiber 4.4 micrometers across was able to bend into a nearly circular shape, with a […]
