Importance of the radiations in water splitting for hydrogen generation

Published on: 14th March, 2023

The review article examines the production of molecular hydrogen from the decomposition of water by various irradiation methods. The article shows different types of radiation: UV radiation, visible radiation, gamma radiation, X-ray radiation and neutron radiation. Electrons generated by radiation inside a nanoparticle of radius R suspense in fluid water are diffused with equal probability in all directions inside the particle and gradually lose their kinetic energy as a result of elastic and inelastic collisions. Some of these electrons are transported to the nanoparticle surface during the physical and physicochemical stages of the process and emitted into the water. It is extremely important for the formation of nanostructured materials after exposure to ordered nanostructure from the new phase with a period of a few nanometers, promoting the preservation of the properties of materials under high irradiation.

From Ashes to Life - The Indestructible D. radiodurans

Published on: 15th July, 2024

Deinococcus radiodurans (D. radiodurans) was accidentally discovered in 1956 when cans of ground meat were exposed to massive doses of ionizing gamma radiation, intended to kill dangerous bacteria. The bacterium can survive doses of radiation, even up to 1,000 times that which is deadly to humans. Among biologists and biophysicists, D. radiodurans is often humorously called “Conan the Bacterium.” This extreme radioresistance of the bacterium has been attributed to its ability to protect the proteome from ROS, which originates from water radiolysis, and also to carry out the effective repair of a large amount of DNA damage.
