With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents, should the need arise. In the American Chemical Society journal ACS Nano, they describe new spherical micromotors that rapidly neutralize chemical and biological agents and use water as fuel.
Hot foam may soon send criminals running if they damage ATM. ETH researchers have developed a special film that triggers an intense reaction when destroyed. The idea originates from a beetle that uses a gas explosion to fend off attackers.
Sandia National Laboratories has signed a pair of cooperative research and development agreements (CRADAs) that could broadly add to the labs’ research into combustion, defense, energy and nuclear security.
