Preparation of concentrated suspensions of graphene oxide from graphene for the preparation of derivatives, functionalized graphene oxide samples and for the preparation of composites.\n

The technical solution provides seismically resistant connection of wooden floor structures with supporting walls. The device is primarily designed to increase the resistance and ensuring the integrity of masonry buildings with wooden ceilings during seismic action and its dissipation by friction.

A suspension of nanoparticles of graphene prepared from nature graphite for use as a filler in the aqueous polymer composites, transparent coatings and for the synthesis of high quality graphene oxide.\n

Telemetric water level monitoring station in a robust IP67 metal shield is designed for the water level measurements in open profiles and boreholes. It calculates actual discharges and total runoff volumes using predefined consumption curves. It is equipped by several input canals suitable for the connection to other qualitative sensors, e.g., water chemistry, rainfall gauge, soil tensiometers, etc. The station transmits the data using the build-in GSM module into the internet server and simultaneously it can send out and receive warning and controlling SMS. As the power consumption is very low and SW works in a power save mode it can operate 6 months without the exchange of an accumulator (12V/9Ah). In order to recharge the accumulator by a solar panel, the station contains an efficient power supply regulator. The station is equipped by a plentiful software packages enabling, besides other things, autodiagnostic processes using various control canals.

Use of an aqueous suspension of nanoparticles of zinc oxide and suspension of nanoparticles of zinc peroxo-oxide for applications in barrier coatings.

The technical solution relates to a bifunctional heterogeneous catalyst, containing reducing (metallic) and basic active centres, which is effective in the hydrogenolysis of sugar alcohols with 5 to 6 carbon atoms in the chain. It is also sufficiently stable in the reaction medium, which contains up to 90 % wt. water. The heterogeneous catalyst for the hydrogenolysis of polyols, containing Cu, Mg and Fe according to the technical solution, is also characterized by high mechanical strength and a combination of activity, selectivity, stability in the reaction medium and mechanical strength surpasses previously known Cu catalysts which can be used for the hydrogenolysis of sorbitol without the need of alkali addition into the hydrogenolysis feedstock.

In cooperation of CLASSIC Oil s.r.o., Buštěhrad, the Institute of Thermomechanics of the Czech Academy of Sciences, and the Institute of Chemical Process Fundamentals of the Czech Academy of Sciences, an antifreeze fluid was developed and measured, containing nanoparticles improving the thermal conductivity. The liquid contains 30 to 70% by weight of 2,2‘- [ethane-1,2-diyl bis (oxy)] diethanol, 10 to 30% by weight of propane-1,2,3-triol, 10 to 20% by weight of propan-1, 2-diol, 5 to 10% by weight of an inhibition package based on 2-ethylhexanoic acid, adipic acid, tolyltriazole and benzotriazole, 1 to 60% by weight of demineralized water, 0.1% by weight of a biocidal stabilizer, 0.001% by weight anti-ingestion agents, and 0.004% by weight of dye. Graphene nanoparticles with a size of 2 nm make up 0.1 to 2% by weight.

The technical solution concerns equipment for the preparation of liquid additives for asphalt mixtures. The plant is particularly suitable for the production of an additive based on a mixture of methyl esters of higher fatty acids and mineral oils.

The utility model relates to the composition of a hydrophobic colloidal diffusion source of phosphorous for the preparation of doped N-type silicon
