Tomsk scientists will develop a device to neutralize chemical hazards

Scientists from Tomsk State University and the Institute of Problems of Chemical and Energy Technologies SB RAS (Altai region) will develop technology to neutralize hazardous substances spilled during man-made accidents and of military operations. The technology is based on the use of nanoparticles of titanium dioxide, zinc oxide and iron oxide. As Alexander Vorozhtsov, TSU’s vice-rector for research and innovation, told TASS (Russian news agency), scientists will create a pulse generator that sprays neutralizing nanoparticles. The technology is sponsored by a grant from the RSF (Russian Science Foundation) and is expected to be finalized by 2024.

“Let’s say a cloud of toxic chlorine or acetone fumes is coming in, and we spray neutralizing nanoparticles towards the cloud with something like a fire extinguisher. The device will be used in open and closed spaces. The technology is designed to neutralize man-made accidents, but it can also be used in gas attacks during military operations, ”explained Alexander Vorozhtsov.

The technology will be applied to many types of hazardous substances.

“Nanoparticles have a large specific surface area, which makes neutralization more efficient,” added Alexander Vorozhtsov.

The joint cost of the interdisciplinary grant, involving engineers, chemists, biologists and the use of mathematical models, is 54 million rubles.
