In the south of the Russian Far East, a new perspective source of minerals was pioneered, which is the metal-bearing high carbon rocks of the Ruzhinskaya square. The rocks are rich in crystalline graphite, gold, platinum and carbon nanostructures (fullerene, nanotubes and diamond-like carbon). The technique of extract…
The electronic structure and x-ray magnetic circular dichroism (XMCD) spectra of the ferromagnetic superconductor UCoGe at the U N4,5, Ge and Co K and Co L2,3 edges were investigated theoretically from first principles, using the fully relativistic Dirac linear muffin-tin orbital band structure method. The electronic…
Mg-8Zn-0.5Zr-0.5Gd alloy was prepared by high pressure solidification. Effect of high pressure on microstructure, micro-hardness and corrosion behavior in Hank's solution of the Mg-8Zn-0.5Zr-0.5Gd alloy were investigated by means of optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectro…
Dye-sensitized solar cell (DSSC) is a device that converts solar energy into electrical energy. The magnitude of the efficiency of DSSC is mainly based on the amount of dye absorbed by the surface of TiO 2 . In this work, used natural dye extracted from leaves Rhoeo spathacea. The dye partially used to immerse of TiO…
Der Vortrag widmet sich der Validierung der Verbundfestigkeit von optischen Schicht-/Substrat-systemen mittels Zentrifugentechnologie und diskutiert Versagensbilder und gemessene Werte der Verbundfestigkeit ausgewahlter feinoptischer bzw. ophtalmischer Schichten in Abhangigkeit von den plasto-elastischen Eigenschaften…
In this paper a functional graded material (FGM) thermal barrier coating (TBC) is prepared using Atmospheric Plasma Spraying (APS) method. The FGM layers were deposited by varying the feeding ratio of CYSZ/NiCrAlY and conventional CYSZ on a NiCrALY-coated Inconel 738 substrates. Hot corrosion behavior, bonding strengt…
It was described the photoelectric effect in thin sandwich metal-ferroelectric-metal system. The effect was observed in doped lithium niobate crystals with two electrodes of different metals. The effect is observed only in doped lithium niobate crystals and has a maximum for concentrations of impurities of iron around…
Lanthanide-doped up-converting nanoparticles (UCNPs) are promising reporters for medical diagnostics and bioimaging, which are excited in the near infrared (NIR) by multiphoton absorption processes, and show multiple narrow emission bands in the visible (vis) and NIR, long luminescence lifetimes in the μs range, and e…
The raw values behind graphs, statistical averages, or figures presented in the study of Evaluation of complex toxicity of canbon nanotubes and sodium pentachlorophenol based on earthworm coelomocytes test were uploaded to a stable public repository Figshare as required.
以钛铁矿为原料，通过浓盐酸浸出法提取了其中的氧化钛和氧化铁，浸出率高达~97%，氧化钛和氧化铁的收率分别为~53%和~80%。并以氧化铁为原料合成了Fe3O4@SiO2磁核，通过固相合成及软化学剥离制备了二维氧化钛纳米片(TNSs)溶胶，并进一步制备了可磁分离的Fe3O4@SiO2@TNSs复合材料。以可见光或太阳光为光源，催化剂在H2O2辅助下表现出优异的活性，其降解RhB的速率常数分别是商品氧化钛P25以及Fe3O4/N-TiO2光催化剂的14.5倍和20.4倍。此外，相比于P25纳米氧化钛的难以回收，合成的Fe3O4@SiO2@TNSs催化剂在外磁场作用下实现快速回收。催化剂表现出极佳的稳定性和循环性，五次重复使用后仍能几乎…
It has been required to improve the heat efficiency of thermal power generation system for the sake of mitigation of the global warming and resource depletion problems. For improving the heat efficiency, it is effective to increase the steam temperature, and as a result, appropriate heat-resistant alloys are needed. A…
The vessel wall response shows a good agreement between the numerical predictions of and experimental data using the limit load approach. Further work is continuing to understand the thermohydraulic response and the boundary conditions for material modelling. As shown in figure 2 there was one BLEVE of a bare tank con…
The effect of polyketone (PK) γ-irradiation dose on the energy characteristics of the PK surface, the specific free surface energy, and the interfacial energy at the boundary between polar (water) and nonpolar (octane) liquids has been studied for the first time. The most significant changes in the energy characterist…
In this work, the simulations of magnetic properties of nano-sized manganese ferrite particles with zinc replacement were performed. The percentage of replacement laid in range from 0% to 80%. The parameters of particles, including exchange integrals, were taken from experimental data received for Mn x Zn 1-x Fe 2 O 4…
We studied the temperature and concentration conditions of education and the field of LC – phase of existence in sulfuric acid solutions poliamidbenzimidazola. The polarization–optical methods and the structural features of biphasic and anisotropic areas and built plots the phase diagram of the concentrated solutions…
It is shown in this paper that traditional formulas for reactivity effects calculation based on diffusion approximation small-perturbation theory sometimes need updating. The corresponding specifications are provided. These are caused by the unbalance of neutron "leakages" between subdomains (zones, cells, fuel subass…
A silicate catalyst prepared which has a mezopore type (MCM-41) ,by manner that condensation where the interaction between Tetra Ethyl Ortho Silicate (TEOS) with 3-Mercapto Propyl Tri-methoxy Silane (MPTS), in the presence of superficial active substance {Cetyl Trimethyl Ammonium Bromide(C 16 TAB)}at room temperature.…
Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. This thesis concerns the synthesis of highly porous carbon foam…
It is believed that the accumulation of all-trans -retinal (ATR) in retinal cells is responsible for photoinduced damage to the retina. However, ATR is formed within a photoreceptor cell disk in the process of photolysis and transferred to the cell cytoplasm, where it is converted in a high yield into the nonphototoxi…
Thiol-ene photopolymerizations provide a robust and versatile synthetic pathway to functional materials, and owing to the radical step-growth nature of polymerization and the resulting homogenous network structure, provide non-convoluted insight into how network chemistry influences and dictates macromolecular propert…
