Structure and physical properties of nanocomposites: opal matrix – titanium oxide The conditions for the formation of nanocomposites based on lattice packings SiO2 nanospheres (opal matrices) with crystallites of titanium oxide in interspherical nanospacing are considered. The composition and structure of the nanocomposites were studied by electron microscopy, X-ray diffraction and Raman spectroscopy. Results of measuring of the frequency dependences of real and imaginary components of the permittivity and microwave conductivity of obtained nanostructures are viewed.

Russian electronic components for extreme conditions: silicon carbide industry founded by LETI The most popular technology when creating SiC-based devices using the absolutely prevalent epitaxial technology is changing the type of adding impurity in the reactor without its "decompression", directly during
the epitaxial growth. The modern epitaxial reactor owned by LETI enables this process, including
the automatic loading of substrates.
Development of a piezoelectric energy harvester for navigation support of railway transport Investigation of vibration parameters of the freight cars is presented. Several designs of piezoelectric energy harvester are proposed for the efficient conversion of mechanical vibrations into electrical power. Based on experimental studies a comparison of different types and designs of energy harvester is performed. The amount of energy required for wireless transceiver for monitoring location of a vehicle is evaluated. Obtained data can be used for development of production technology of the piezoelectric energy harvester to provide autonomous power supply for freight cars.
