The results of an atomic force microscopy study the surface nickel coating doped with phosphorus 2 μm thick obtained by cathodic arc evaporation after annealing at temperatures from 100 to 500 °C are presented. morphology changes significantly increase in temperature. A negative high correlation between specific energy and roughness was established. mechanical properties (microhardness, elastic...

Streptococcal group A, B, and C carbohydrates were analyzed by counterimmunoelectrophoresis, immunoelectrophoresis, and inhibition of immunoprecipitation. Extracts of streptococci group A or C were shown by counterimmunoelectrophoresis to contain both anodic and cathodic migrating components. In immunoelectrophoresis, group A and C substances formed a continuous precipitation line stretching fr...

Immunoelectrophoretic analysis of 25-day-old newborn and adult rat livers verified the presence of a 6-arc pattern of catalase observed earlier for purified rat hepatic catalase and for liver homogenates. Application of the immunoelectrophoretic method to fetal and newborn liver homogenates revealed a gradual shift from predominantly anodic arcs present in the fetal and early newborn period to ...
