  • Patent number: 11697892
    Abstract: A device including one or more nozzles having a tubular fiber spinning needle and method for producing non-toxic polymer fibers and microfibrous and nanofibrous polymer materials made thereof on a small to large scale using a wide range of synthetic polymers and bio-based polymers. The device and method enable continuous in-line production of polymer fibers at a high fiber production rate energy efficiently and safely. The increased polymer fiber production rate is achieved by the at least one nozzle that enables a centrifugal force acting upon the tubular fiber spinning needle causing rotational motion of the tubular fiber spinning needle and higher polymer injection rates per nozzle.

  • Patent number: 8753536
    Abstract: Method of preparation of surface coating of variable transmittance and an electro-optical layered appliance including the same comprises dispersing of liquid crystal microdroplets in hydrolyzable and polymerizable precursors and applying obtained mixture on a surface by spraying. Applying the material to the surface by spraying is intrinsically related to the synthesis processes because the properties of the surrounding environment (i.e. content of water and acidity, UV radiation) and the chemical reactions that take place during spraying have considerable influence on the properties (i.e. driving voltage, thickness of obtained layer). Obtained layered appliance comprises of a matrix material with dispersed microdroplets of liquid crystal obtained by the described method, electrically conductive transparent electrodes with contacts, a dielectric material, substrate and covering layers.

  • Patent number: 8597610
    Abstract: In the current invention a method for the preparation of an oxide material was described that involves bringing the sol onto the substrate, the gelation of the solution and thermal treatment of the gel. Alkoxides are used as precursor materials for the sol preparation and substrate free structures are employed for the manufacturing of the oxide material. A gel film with thickness ranging from 5 nm to 1 ?m is created onto the sol layer. The gelled film is separated into pieces by self organizing and the gelled part is disconnected from the substrate. Substrate free tubular structures with diameters ranging from 0.01-100 ?m are formed of the gel film which are then heated at temperature range of 200-1600 C during a period of 5 minutes to 10 hours. The manufactured oxide materials are employed as catalysts, gas sensors, stationary phases of chromatographic columns, composite materials, thermal isolation materials and micro- or nano electronic mechanical systems (MEMS or NEMS) components.
