Nanoindentation and Strain Characteristics of Nanostructured Boride/Nitride Films

The hardness, elastic modulus, and elastic recovery of nanostructured boride/nitride films 1–2 µm thick have been investigated by the nanoindentation technique under the maximum loads over a wide range (from 5 to 100 mN). It is demonstrated that only the hardness parameters remain constant at small loads (5–30 mN). The data obtained are discussed and compared with the parameters determined by other methods

New Heterogeneous Nanostructured Catalysts Based on Transition Metal Nanoparticles and Hexagonal Boron Nitride

Abstract: The structure of new heterogeneous FePt/h-BN nanomaterials and their catalytic activity in the model reaction of carbon monoxide oxidation have been studied. The structure and surface composition were analyzed by methods of transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. It is established that the new materials exhibit pronounced catalytic activity and can provide complete CO conversion at a temperature of 250°C. The process of thermal activation involves ordering of the structure of FePt nanoparticles.</p
