We design, model, optimize and fabricate cold electron cathodes that are specifically designed for X-ray sources. Micromachining patterning process, which enhanced edge effect, significantly improved its emission performance. High bonding strength was achieved by a preferred high temperature annealing process, which r…
Research was carried out to investigate the Efficacy of Calotropics procera Leaf Extract and Dyclobos against ectoparasites (fleas) on sheep. Effect of Calotropis procera Leaf Extract and Dyclobos on weight, Packed Cell Volume (PCV) and repellence were studied on sheep. A total number of 18 sheep were examined for the…
Особенности получения и строения кристаллов LiNbO 3 : Zn в области концентрационного порога 6.76 mol.%ZnО © Н.В.Сидоров
This thesis examines the development of synthetic methods to attach anti-cancer agents onto the surface of nanoparticles. The established method has great future potential as it allows the incorporation of a wide variety of molecules and could ultimately lead to the development of more effective cancer therapeutic age…
Исследовалось влияние введения водорода на колебательные спектры и электрофизические свойства образцов с дислокационными сетками (ДС) на интерфейсе сращенных пластин кремния. Для увеличения чувствительности измерений и выделения сигнала ДС в спектрах комбинационного рассеяния использовались образцы в виде стандартных…

Ultra High Temperature Ceramics (UHTCs) are the most promising candidates for high temperature applications in extreme environments, such as conditions experienced during re-entry of out space flying objects, for their known high melting points, good chemical and thermal stability and high thermal conductivity. To imp…
A comparison of the efficiencies of the power supplies produced based on the β-radiation sources has been carried out. The factors decreasing the efficiency of the device have been revealed. The results of the experimental studies and calculations of the efficiency of the direct energy conversion of Ni-63 β-radiation…
The objective of this thesis was to investigate a mechanical dry powder coating approach to improve flow and fluidization of cohesive powder for producing direct compaction tablets. A fine cohesive ibuprofen powder (D₅₀=25 µm) with a low-melting point (~76°C) was coated with varying coating materials (magnesium steara…
A preliminary study of lead-oxide cooled fast reactor with natural uranium as an input fuel using reactor shuffling strategy has been conducted. In this study, reactor core is divided into four zone with the same volume, each zone use different uranium enrichment. The enrichment number is estimated so that in the end…
The biography and scientific results of the prominent Soviet-Russian physicist Dmitry Ivanenko are presented. Dramatic career of the talented physicist is described on the historic background of dramatic period of Soviet Union. Professor Ivanenko appears as an figure of Novel level by his talent of Physicist not get r…

The photoluminescence and X ray diffraction of the mixture of ZnO + 1.0% C nanocrystals (NCs) have been studied before and after intensive mechanical processing (MP) with the aim to identify the nature of emission bands and radiative defects. The study reflects the diversity of physical processes occurring during MP:…
The paper describes the developed technology of the creation of wear-resistant surfaces of friction pairs, which have oil pockets for the holding of lubricants, which are situated between rollers, formed on flat surfaces with the help of a fast-rotating disk. The treatment of friction surface is performed by the disk…
Представлены результаты феноменологического исследования кинетики аномального фотоотклика слоистого сегнетоэлектрика-полупроводника TlGaSe2 в области температур T~170-280 K, соответствующей параэлектрической фазе кристалла. С учетом изменений с температурой кинетики фотоотклика предложены основные механизмы возникнове…
To study the deformation mechanism of high manganese steel at high-speed machining and the influence of cutting parameters on a quality of machined surface and on a tool wear, we conducted a serial of tests cutting high manganese steel with metal ceramic tool. By observing the macroscopic chip and measuring its micro-…
Exposure to ionizing radiation has been found to induce changes in poly(vinylidene fluoride) (PVDF) homopolymers. The high dose gamma irradiation process induces the formation of C=C and C=O bonds in its [CH2-CF2]n main chain. The irradiation also provokes crosslinking and chain scission. All these radio-induced defec…
Correction for ‘The reactivity of Ti10Zr alloy in biological and electrochemical systems in the presence of chitosan’ by Vlad Gabriel Vasilescu et al. , RSC Adv. , 2017, 7 , 13919–13927.
Ge-dot/SiO 2 /SiGe-channel photoMOSFETs are demonstrated on Si substrate. A decrease in the dot size and gate oxide thickness significantly enhances the photoresponsivity (9000A/W) with 6nW under 850nm illumination, and improves response time (0.48ns) and power consumption.
Increasing use of nanomaterials (NMs) in a wide range of consumer products has raised concerns about their impacts on natural and engineered ecosystems. NMs released into the ecosystems will potentially influence organisms at all levels of the food chain. Microorganisms are at a low trophic level and play critical rol…
