层状双金属氢氧化物(LDH)是一类具有层状结构的新型功能材料，近年来基于LDH的核壳结构纳米复合材料由于具有组成结构多样化、组分间呈现协同效应、性能容易调控等特点，其制备与应用研究引起了广泛关注。本文首先综述了最近几年基于LDH的核壳结构纳米复合材料的常用制备方法,主要包括共沉淀法、自组装法和原位生长法，并对这些方法的优缺点进行了分析；然后又讨论了基于LDH的核壳结构纳米复合材料的应用现状，着重阐述了该类材料在吸附、催化、超级电容器和生物医学等方面的应用情况；最后也对该领域存在的问题及其发展趋势进行了总结讨论。 Layered double hydroxide (LDH) is a novel functional materia…
It was found in other papers by Michael John Sarnowski that there appears to be a relationship between a process similar to Bremsstrahlung and Cherenkov radiation and the mass ratios of the Proton, Electron, Muon, and Tau to the Neutron. This correlation also is used to make predictions for these ratios and the Sommer…
The characteristics of interband and exponential optical absorption of leucosapphire and polycrystalline corundum (polycor) after irradiation with chromium ions and subsequent annealing in vacuum at 300–1800 K and in air at 300–800 K are studied. Contributions of defects with different thermal and chemical stability i…
Safety is an important concern in Nuclear Power Plants because of large radioactive inventory produced during operations. Therefore, an accurate analysis of the system under normal and accidental conditions is necessary and relies on the use of complex computational capabilities. In particular, thermal-hydraulic syste…
Pneumothorax, or a collapsed lung, is a serious medical condition resulting when air or fluid escapes the lung into the chest cavity and prevents the lung from inflating. Few viable means of sealing the damaged and leaking tissues are currently available, leading to longer hospital stays, multiple interventions, and i…
Analytical and experimental studies of the azimuthal module of two-component vibrational micromechanical gyroscope were conducted. It is shown that the micromechanical gyroscope is a system with distributed parameters. The frequency analysis is performed using software T-Flex. The influence of mechanical disturbances…
Bone tissue engineering has become a promising alternative for the use of autologous bone in the reconstruction of bone defects in oral regenerative medicine. The main goal of this thesis was to investigate behavior of human adipose stem cells (hASCs) and fibroblasts in/on resin-based composites, natural polymer fibri…

The results of studies on the impact of an electron beam with the energy of 1-2 MeV on diffusion processes in materials with ionic bonds are presented in the paper. Used electron beam intensity is allowed to provide heating of the material to temperatures of 1600 K. Diffusion of Na, Mg, Al ions into single crystals KB…
This thesis examines the chemistry of the dicyanonitrosomethanide (dcnm) anion and how it may undergo the transition metal promoted addition of a nucleophile as a means of in situ ligand formation. A computational study indicated that the addition of water to a nitrile group of the dcnm anion only gives the anti-isome…
We have investigated the heat resistance properties of Fe-W alloy films electroplated using an ion exchange membranes - multiple anodes systems. The room temperature hardness of Fe-W alloy film increased with increasing heat treatment temperature and reached HV1200 after the heat treatment at 700°C. While the film was…
3-Aminophenylboronic acid (APBA) and the complex Ru(bpy)2(phendione)2+ (bpy = 2,2′-bipyridine, phendione = 1,10-phenanthroline-5,6-dione) were found to be useful building blocks for preparing photomagnetic carbon surfaces. Scanning tunneling microscopy (STM) showed that when APBA was diazotized in acidic sodium nitrit…
Parameters of instruments developed on the basis of previously calculated different electron-optical systems for the analysis of charged particle flows were considered in the present work. Recommendations for their application in various fields of electron spectroscopy for the analysis of a solid surface were given.
We have fabricated highly crystallized thin films of niobium-doped anatase type titania (Ti1−xNbxO2) to examine the relationship between the electronic transport properties and the plasmonic response. Ti1−xNbxO2 thin films were epitaxially grown on LaTiO3 substrates by using pulsed laser deposition. Attenuated total r…
The effect of the uncertainties of the isotopic composition of the reprocessed uranium on its enrichment process in gas centrifuge cascades while diluting it by adding low-enriched uranium (LEU) and waste uranium. It is shown that changing the content of 232 U and 236 U isotopes in the initial reprocessed uranium with…
The development of an experimental method for the determination of stress concentration coefficient by the photometric analysis of surface reflectivity of material near stress concentrator and at a distance from it is considered in the paper. The experiments were performed with the AD-19 aluminum alloy samples under f…
Production of permanent magnets on basis of rare earth elements (REE) is implemented by means of powder metallurgy, therefore a technologically important operation is the multistage mechanical crushing of materials to the extent of domains. The promising technique of crushing of magnetic materials is their consistent…
本論文主要介紹了一種用來空間上調節光的傳播方向跟偏振態的光學薄膜結構。這種結構包含多層圖案化的雙折射薄膜,每一層都是由液晶聚合物（LCP）構成,這些聚合物的光軸方向由一層圖案化的光配向層控制而變化。這種光調制器有兩層功能層,第一層的設計是圖案化的偏振光柵,光柵向量方向可以空間上變化,已達到空間調制光的傳播方向的作用,第二層是一層圖案化的光延遲膜,可以調節出射光的偏振態。這種多薄結構的厚度小于1μm,有助于提供高分辨率的光波前結構。它還可以當做光掩模,用來產生多疇配向結構的光配向層,應用到現代液晶顯示器的制造中。為了驗證這種結構的實用性,我們成功地制作了這種多層膜結構,并用它在單次曝光的條件下制作了一個兩域光配向結構的液晶盒。這種光…
