Study of porous monolithic sio2 prepeared by sol-gel method
For applications as catalyst supports in flow reactors, porous silica monoliths require a combination of connected pores of micron-scale and nm-scale pores. We have synthesised a range porous silica monoliths, characterised their nm-scale pores and measured their permeability coefficients k. It can be controlled by adjustment of the polymer/silane concentration ratio, whilst maintaining the specific surface area and nm-scale porosity approximately constant

In the process of the research, the existing methods of trenchless pipeline laying, the calculation of the main characteristics of the underwater crossing, the selection of the protective device, the study of the stress-strain state of the pipeline using finite element modeling in the software complex Ansys were compared. As a result of the research, optimal parameters of the underwater transition were selected, the finite element method in the software complex Ansys determined the stress-strain state of the pipeline with the protective device and without it
Growth and characterisation of AlGaN/GaN-HEMTs on silicon substrates,
In order to analyse and to compare the properties of AlGaN/GaN HEMT on silicon and on sapphire substrates, studies on both layers and device types have been performed. Besides the substantially lower substrate costs compared to SiC, the use of silicon as substrate provides the advantage of a higher thermal conductivity compared to sapphire allowing a more efficient heat removal from the device and thus higher RF power densities. On silicon, up to 900 nm of GaN as well as HEMT structures have been deposited and characterised regarding their structural, optical and electrical properties. HEMT devices with various gate lengths were processed and measured onwafer under continuous and pulsed operation conditions. The properties of the layers and devices on silicon substrates are developing to become comparable to those based on sapphire and silicon carbide
