A team of physicists from Immanuel Kant Baltic Federal University (BFU), with colleagues from National Research Nuclear University MEPhl (NRNU MEPhl), have developed a tungsten oxide-based detector of hydrogen in gas mixes.
Hydrogen molecules have the smallest mass and size meaning the gas is difficult to keep in any vessel as it leaks from almost any opening. Hydrogen leakages are extremely dangerous in the industry, as when mixed with oxygen, hydrogen causes an explosive mix known as the detonating gas.
To prevent hydrogen leakages, its concentration in an industrial facility should be constantly monitored, this is usually carried out with gas detectors. Detectors are based on the ability of gases to change the electrical conductivity of metals upon contact with them.
