A thin-film semiconductor resistor is formed as a 3D porous nanostructure (SiO2)40%(SnO2)50%(ZnO)10% by application of a sol of orthosilicic acid, containing tin and zinc hydroxide, onto a silicon substrate with the help of a centrifuge and subsequent annealing, which is prepared in two stages, at the first stage they mix tetraethoxysilane and ethyl alcohol, then at the second stage into the received solution they add distilled water, hydrochloric acid and tin chloride dihydrate (SnCl2·2H2O), and also additionally add zinc chloride (ZnCl2).

Method of obtaining anode aluminium oxide with highly ordered porous structure and method of forming arrays of anisotropic nanostructures on its base

Invention relates to method of obtaining porous film with highly ordered system of pores, forming strict hexagonal grid, as well as to method of forming highly ordered arrays of anisotropic structures. Monocrystalline aluminium with crystallographic orientation A1 (111), A1(110) are used as initial material to realise method of obtaining porous film with highly ordered system of pores, forming strict hexagonal grid, by anode aluminium oxidation. Method of forming highly ordered arrays of anisotropic nanostructures is realised by electrochemical precipitation of introduced substance from respective solutions of electrolytes in channels of porous matrix. Porous film, obtained by said method, is used as matrix.

Calcipotriol monohydrate nanocrystals

Invention refers to pharmaceutics and represents a suspension for treating psoriasis, containing calcipotriol monohydrate in the form of nanocrystals having the particle size distribution within the range of 200-600 nm; the particles are dispersed in an aqueous phase containing a non-ionic polymer surfactant specified in a group consisting of a surfactant in the form of poloxamers or polysorbates, in the amount of 0.01-5 wt % calculated using a suspension for preventing development of aggregation and/or calcipotriol monohydrate nanocrystal growth; the calcipotriol monohydrate nanocrystals are produced in the suspension by processing the suspension by a method involving the stages of reduction in crystalline calcipotriol monohydrate particle size in an aqueous phase to form microparticles having the particle size distribution within the approximate range of 5-20 mcm and the average approximate particle size of 10 mcm; the suspension is exposed to three high-pressure homogenisation cycles for 7-15 minutes each; in the first, second and third cycles, the pressure makes 300-800 bars, 800-1,200 bars and 1,200-1,700 bars respectively.

Method of obtaining nanocrystalline silicate-substituted carbonatehydroxyapatite

Invention relates to method of obtaining nanocrystalline silicate-substituted carbonatehydroxyapatite (CHA), which includes mixing solutions of salts of calcium, phosphate and silicate, settling, filtering, washing from mother liquor and drying, solutions of calcium nitrate tetrahydrate, anhydrous disubstituted ammonium phosphate, sodium methasilicate pentahydrate are mixed with ratio of concentrations Ca/(P+Si) equal 1.70, and part of silicate-ions in the total quantity of sediment-forming anions ( X S i O 4 4 − = C S i O 4 4 − / ( C P O 4 4 − + C S i O 4 4 − ) ) , constituting not more than 30 mol. %, pH is supported at level 9.00-12.00, obtained as a result of precipitation solid phase is kept under mother liquor for 2 days at temperature 22-25°C, then filtered out, washed with distillated water and dried at 80°C to constant weight. CHA considering created structure defectiveness of is characterised by higher solubility in physiological solution, and thereupon can be applied for formation of calcium-phosphate coatings on metal implants, as well as for creation of novel ceramic and composite materials for traumatology, orthopaedics and maxillofacial surgery.
