An EM Transistor Based Brain-Processor Interface

Sklyar R., Independent researcher, UA

The external (non-implantable) brain machine interface which based on the array of solid-state electromagnetic transistors (EMTs) has been advanced. Rejection of environmental noise can be improved by measuring a magnetic field difference by the radial [...]

Pierced Sensor for Nano-Microscope

Sklyar R., Independent researcher, UA

For nonzero drain voltages the superconducting field-effect transistor (SuFET) absorbs low- frequency power of the average Josphson current and re-emits this power at extremely high frequencies. The feasibility of the transistor function on a yarn-like [...]

Some Properties of Electro-Deposited Fullerene Coatings

Ershova O.G., Khotynenko N.G., Golovko E.I., Pishuk V.K., Mil’to O.V., Kopylova L.I., Vlasenko A.Yu., Institute for Problems of Materials Science of NAS of Ukraine, UA

Earlier we have demonstrated the principal possibility to produce fullerene-containing coatings on metal electrodes by the electrochemical method and the dependence of their structure on the chemical composition of the working solution and experimental conditions. [...]

Synthesis of Carbon Nanostructures in Liquid Helium

Schur D.V., Bogolepov V.A., Savenko A.F., Institute for Problems of Materials Science of NAS of Ukraine, UA

At present synthesis of carbon nanostructures is mainly performed in different scientific groups by any one method. For this reason not everyone has possibility to compare peculiarities of synthesis of the same product by different [...]

Synthesis of Nanostructures in Chlorine-Containing Media

Zaginaichenko S.Yu., Dubovoy A.G., Institute for Problems of Materials Science of NAS of Ukraine, UA

Modification of carbon nanostructures by different chemical elements opens an opportunity for synthesis of materials of a new generation for different applications. Filling carbon nanotubes with one or other element will allow for conferring different [...]

CNT and Organic FETs Based Two-Way Transducing of the Neurosignals

Sklyar R., Independent researcher, UA

A superconducting field-effect transistor (SuFET) based neurotransducer (sensor) with carbon nanotubes (CNT) or pickup coil kind of input circuit for the nerve and neuron impulse has been designed. Electronic or ionic currents in conductors or [...]

Identification of Endohedral Metallofullerenes by Method of UV-VIS Spectroscopy

Dobrovolsky V.D., Anikina N.S., Krivuschenko O.Ya., Chuprov S.S., Mil’to O.V., Zolotarenko A.D., Institute for Problems of Materials Science of NAS of Ukraine, UA

As the class of new synthesized compounds endofullerenes attract a close attention of theorists and practicians and especially after appearance of possibility to produce them in macroscopic amounts. This has allowed the investigation of their [...]

Preparation of BN-Si3N4 Nanostructured Composites

Krushinskaya L.F., Makarenko G.N., Uvarova I.V., Timofeeva I.I., Isayeva L.P., Institute for Problems of Materials Science NAS of Ukraine, UA

The process of boron silicide nitration in nitrogen and ammonia media has been studied. The products of nitration were established the composite powders of boron and silicon nitrides. By using the boron silicide compounds instead [...]

Modelling of Processes of Photoacoustic Diagnostic with Piezoelectric Detection

Vertsanova O., Perlov I., Tsyganok B., National Technical University of Ukraine, UA

Authors developed the one-dimensional mathematical model of piezoelectric detection of photoacoustic effect in thermally thick and optically opaque sample with subsurface defect. The model is developed in view of the assumptions of ideally rigid connection [...]

Numerical Simulation of Periodical Distribution of Antisite Defects in Irradiated Semiconductors

Mykhaylovskyy V.V., Russell K.C., Sugakov V.I., Academy of Science of Ukraine, UA

A simulation of radiation-induced instability in binary semiconductors, such as GaAs, was fulfilled. The instability is connected with antisite defects accumulated. It was shown that the number of antisite defects in crystal under irradiation can [...]
