- ПубликацияТолько метаданныеMagnetron Plasma Sputter Deposited W-Layers Permeability Influence on the Cycling Stability of thin Film Electrochromic Modules(2021) Kravchenko, V. V.; Knyazhev, D. P.; Bernt, D. D.; Pisarev, A. A.; Бернт, Дмитрий Дмитриевич; Писарев, Александр Александрович© 2021, Pleiades Publishing, Ltd.Abstract: The processes of thin film electrochromic modules degradation during their cycling through the formation of blisters within the PVD sputtered tungsten oxide electrode layers are considered. The formation of blisters is shown to be caused by the retention of radical components transported into the tungsten films from the underneath layers of the module’s layerstack. Permeability of the ceramic tungsten-oxide layers of varying stoichiometry is studied by the means of thermal desorption spectroscopy and the ways for increasing the cycling sustainability of tungsten layers through their reactive magnetron PVD in deficiency of reactive component of working gas mixture are proposed.
- ПубликацияТолько метаданныеInfluence of drying process on the aluminosilicate fiber hot gases filter element properties(2022) Sizova, A.; Rodimov, O.; Galganova, A.; Lemeshev, D.; Bernt, D.; Бернт, Дмитрий Дмитриевич© 2022 Elsevier Ltd and Techna Group S.r.l.The influence of drying process on the properties of ceramic filter elements for industrial high-temperature gases purification was studied. Filter elements were based on aluminosilicate fiber manufactured via vacuum filtration with the following molding and machining of the workpiece, it's treatment with a colloidal silicon oxide sol binder, and drying with the employment of various processes. Convective drying (CD), microwave drying (MWD) and filter element freezing followed by convective drying (FCD) processes were employed to study the related binder migration and its effect on filter properties. Diffusional redistribution of the binder through the thickness of the filter element's wall decreases in the series CD→FCD→MWD with the accordingly observed improvement of the structural uniformity and mechanical strength of the filters. The tensile strength of samples dehydrated via convective drying, freezing followed by convective drying and microwave drying, all of which then heat-treated at 1000 °C (the assumed maximum operating temperature), is 0.35 MPa, 0.57 MPa and 0.48 MPa, respectively. The pressure drop measured at the specific air flow of 100 m3/m2 is respectively 700Pa, 490Pa and 410Pa.
