Graphene foam can outperform leading commercial gas sensors in detecting potentially dangerous and explosive chemicals, according to new study from Rensselaer Polytechnic Institute.
The new sensor successfully and repeatedly measured ammonia (NH3) and nitrogen dioxide (NO2) at concentrations as small as 20 parts-per-million.
The discovery opens the door for a new generation of gas sensors to be used by bomb squads, law enforcement officials, defence organisations, and in various industrial settings.
