(Via eureakalert.org) Engineers based at the University of Texas at Dallas, have utilised a new technique to exploit the electromechanical properties of specific nanofibers. By creating new structures with the fibres, the team have been able to stretch them up to seven times their original length, while remaining tougher than Kevlar. Kevlar is the material used to make bulletproof vests. It can absorb around 80 joules of energy per gram. These new structures can absorb 98 joules of energy per gram.
