At the so - called glass transition temperature, the relaxation time is on the order of a few minutes. (scientificamerican.com)
Loosely bound water (mostly from urine) is separated using low glass transition temperature hollow - fibre membranes. (treehugger.com)
Additionally, we recently have reported ion - conducting copolymer systems in which judicious choice of taper geometry led to reductions in block glass transition temperatures, which ultimately reduced barriers to ion - transport and enhanced conductivity. (european-mrs.com)
