For the first time, Rutherford backscattering (RBS) and proton-induced x-ray emission (PIXE) using a proton microbeam and a slow positron beam were used to analyze (scan) the surface and near-surface layers of α-Fe after exposure to a low-energy hig

At 723 K, which obviously is the melting point of the oxide B2O3, the mechanism of growth of the oxide on BF changes. Below 723 K the activation energy of growth of oxide is equal to 1.0; above 723 K it is equal to 1.7 eV.

The change in the spatial structure of superhelical and nicked DNA molecules in liquid-crystalline dispersions under micrococcal nuclease treatment was studied. Micrococcal nuclease digestion leads to restructuring from the "nonspecific" packing of c
