Application: Tape wound magnetic cores of HF transformers for airborne control, monitoring and telecommunication systems; magnetic cores for electron optics, including airborne collimator indication systems. Some examples of practical applications:
High grade compact electromagnetic noise filters (CMC) - high magnetic permeability at high frequencies (up to 0.1-3 MHz) is important.
Matching small-size HF transformers - high values of saturation induction Bs and initial permeability of new nanocrystalline alloys allow minimization of dimensions of transformers and induced distortions of transformed and/or transmitted signals.
Chokes of differential filters of small dimensions - high Bs in combination with maximum low core losses at high timing frequencies and elevated temperatures is important.
Electron-optical information display and monitoring systems with minimum overall dimensions - high level of temperature stability of whole complex of magnetic characteristics of cores and their mechanical strength are important.



Nanocomposite Materials Production with Treatment of Gaseous/Vaporous Submicrometer Particles-cleaned Phases


Sector: Manufacturing of Microfiber-Based Composites, Carbon, Metals, Ceramic and Polymer Matrix Composites.
Project Stage: Industrial testing.
Proposal Description: Advanced technique and equipment for production of innovative products of nano-capillary porous materials with new impregnation technologies in module installation usage. The proposed technology was developed by a leading Ukrainian R&D Center.
The main principle of the proposed advanced technology is based on the following approach: articles made from capillary-porous materials are preliminary heated by known means and subsequently treated with superheated vapors of the impregnating liquid (or vapors of other substances that readily dissolve in or react with the impregnating liquid). Then, the articles are immersed into the impregnating liquid which has the temperature lower than the temperature of vapor condensation. Implementation of the proposed technology does not require complex technological equipment. It is sufficient to have an impregnating chamber operating under atmospheric pressure, loading/unloading devices and heating devices (aerodynamic, induction, convective, etc.). Also, the equipment should include an apparatus for evaporation and superheating of vapors of impregnating liquid.
Application: The proposed technology relates to impregnation of capillary-porous materials (CPM) with liquid solutions. The technology makes it possible to improve design and build materials and devices on an atomic scale for manufacturing of Nano- and Microfiber-Based Composites, Carbon, Metals, Ceramic and Polymer Matrix Composites. Developing synthetic nanostructures on this scale will lead to many new and improved technologies related to microelectronics, glass-fiber optics, and semiconductors, etc.



Ultramicrodispersed Powders from Secondary Polyterafluoreethylene (PTFE) Raw Materials


Sector: Industrial waste processing.
Project Stage: Further development of technology, sales and marketing.
Technology Description: New technology and prototype of block-module installation for production of microdispersed powders (UDP) and emulsions of fluorocarbon polymer (FP). The proposed technology utilizes a thermochemical method of destruction of secondary raw materials and FP waste in a flow of inert gas. The technology makes it possible to process industrial FP waste into UMD with minimum power inputs. The technological process takes place without contact with external environment, thereby making the proposed technology ecologically friendly. The new technology was developed by a leading Ukrainian R&D and production company. The PTFE pyrolytic thermal destruction plant is designed as block-module unit that includes three modules. The main second module includes a load bunker with a lock dozer, under which main reactionary block is placed. Main mass of supermicrodispersed FP powder is separated from reactionary gases in electric filter, which is connected with the reactor by the pipe line, and is going to the commodity product bunker. The basic technological aggregate of sectionally-module type allows for processing of industrial FP waste into UMD fraction powder of 0.1 – 1.5mkm. Thermochemical destruction in inert gas on reserved cycles without going out in external environment takes place in the module. The PTFE plant can produce 80-100 kg of dry PTFE powder per month.
Application: The proposed technology has a wide range of applications, including pipes and fittings, UMDs, emulsions, gels, impregnated products, composite products (metal + FP, graphite + FP), chemical equipment, medical devices, dry and liquid paint, lubricants and additives.
