Radiation Induced

Radiation-induced homogeneous precipitation in Ni-Be alloys was recently observed by high voltage electron microscopy. A coupling of interstitial flux with solute Be atoms is responsible for the precipitation. The present investigation further shows that precipitation is also induced at thin foil surfaces by electron irradiation under a high vacuum.

ABSTRACTBulk samples of YBa2Cu3O7−x have been homogenously irradiated with 3 MeV electrons at temperatures below 20 K. Whereas the superconducting transition temperature, Tc, drops dramatically with increasing dose the width of the transition remains unchanged (Δ Tc ≤ 1.5 K). The normal state resistance at 100 K increases substantially during the electron irradiation. Several irreproducible experiments can be interpreted with a radiation induced, unstable increase of Tc.

AbstractThe paper is a review of the results obtained in our laboratories from the study on the mechanism and technology of combined electron-beam and biological purification of industrial wastewater from non-biodegradable hard surfactants. They are a mixture of isomeric isobutylnaphthalene sulfonates which is known as nekal and is utilized as an emulsifier in the production of synthetic rubber, for example, at the Voronezh plant in Russia. The electron irradiation is used for the conversion of nekal to biodegradable products by the removal of alkyl or sulfonate groups from the molecule (with the formation of naphthalene sulfonate, alkyl naphthalenes and naphthalene). Different experimental techniques were applied to elucidate the mechanism of the respective radiation-induced processes. For example, it was found by pulse radiolysis that
