ethod of production of colored glass products // 2626477
FIELD: chemistry.SUBSTANCE: method of production of coloured glass products includes the following stages: preparation of raw materials, compilation of charge, melting of glass mass, moulding of products and their subsequent cooling. At the cooling stage, when the glass surface reaches the temperature of 80°C, a composition obtained by ultrasonic mixing of the following components is applied to it: a colloidal polymer base, single-walled carbon nanotubes (SNT), and food colouring agents of a given colour. The content of SNT in the composition ranges from 0.005% to 0.2% of its total mass, and food colouring-from 0.04% to 10% respectively.EFFECT: increasing the adhesion of the coating to the surface of the glass colour and durability of the finished products.1 cl

FIELD: chemistry.SUBSTANCE: nickel nanoparticles immobilized on zeolite are used as the catalyst, the reactants are fed directly to the catalyst by two streams, the first of which is hydrogen supplied at a flow rate of 150-310 l/(kg⋅cath), the second - cyclodiene or cyclotriene supplied at a flow rate of 0.55 l/(kg⋅cath)⋅, and the reaction is carried out at a temperature of 180-240°C.EFFECT: simplification of the method for recovering unsaturated cyclic compounds and a decrease in the reaction time.3 ex
ethod for acceleration of tubular bones distraction regenerate formation // 2626250
FIELD: medicine.SUBSTANCE: immediately after receipt of the required segment length, the bone is extended by another 4 mm. A carbon nanostructure cylindrical implant with ends having the form of truncated cone is placed into the bone regenerate, diameter of the implant is 30% of the bone diameter, and its length exceeds the required value of elongation by 4 mm. After implant insertion the bone fragments are brought together to the required value of elongation so that the ends of the implant were introduced into the medullary channels of proximal and distal bone fragments (2 mm for each piece). Fixing is performed using the device to form a strong supporting ability of the bone-carbon unit.EFFECT: method can shorten the life of hardware fixation, duration of treatment.2 cl, 10 dwg
