It is shown that expansible ettringite forms in the topochemical reaction,and crystallizes in-situ on the surface of unhydrated aluminate minerals and orients radially.
Methods To investigate the changes of appearance, weight increase by hygroscopy and degree of swelling of Vikon-U under different dryness and humidity conditions.
Besides that, prop-1-ene-1,3-sultone is a kind of electrolyte additive, which can effectively restrain ion battery from expanding under the condition of high temperature.
Ambitious future observers might also send out probes that escape the supergalaxy and could serve as reference points for detecting a possible cosmic expansion.
