Koordinationschemie Dieses Buch vermittelt die Grundlagen der Koordinationschemie und Anleitungen zu selbstständig durchzuführenden Synthesen von Metallkomplexen bei unterschied- lichen Schwierigkeitsgraden. Die Anwendungsbreite komplexchemischer Inhalte in der Praxis erschließt dem Studierenden die Nützlichkeit der K…
Thin films of Zinc Oxide (ZnO) having different concentrations were deposited using the Aqueous Chemical Growth (ACG) method. The films were characterized using Rutherford Back Scattering (RBS) spectroscopy for chemical composition and thickness, X-Ray Diffraction (XRD) for crystallographic structure, a UV-VIS spectro…
FFRF, standing for the Fusion-Fission Research Facility represents an option for the next step project of ASIPP (Hefei, China) aiming to a first fusion-fission multifunctional device. FFRF strongly relies on new, Lithium Wall Fusion plasma regimes, the development of which has already started in the US and China. With…
Ideal metallic glasses are the metallic glasses that satisfy electronic structure stability. Previously we have developed a so-calledcluster-plus-glue-atom modeland more recently acluster-resonance modelfor the ideal metallic glasses. Good metallic glass forming compositions always satisfy simple cluster formulas [clu…
The tensile properties of E-glass were determined from the experimental results of fiber bundle testing under a high strain rate. The tests were performed using two types of experimental method. One is the tension-type split Hopkinson bar system, and the other is the universal high-speed tensile-testing machine. As th…
The holographic grating recording efficiency and the coherent self-enhancement efficiency of gratings are experimentally studied depending on the recording light interference fringe visibility in an a-As2S3 chalcogenide film in order to find the minimum visibility. The minimum fringe visibility Mmin = 3.6×10–4 is foun…
In order to analyze the combustion synthesis reactions of Mo-Al intermetallic compounds, Mo/Al premixed compacts were quenched during the combustion synthesis. Additionally, Mo wires were dipped into molten Al, and the compound formation reactions between Mo and molten Al were investigated.From microstructure observat…
One of the most important factors for advanced ceramics preparation is nature of the powders. There are many methods to prepare powders for ceramics, namely, mechanical, thermal decomposition, precipitation, hydrolysis, hydrothermal, melt and quenching, etc. This is a review of powder preparation for advanced ceramics…
The structures, the martensitic transformations and the magnetic properties of ferromagnetic shape memory alloy Mn2NiGa with the loading and the unloading of the external compressive stress are investigated. The plastic deformation occurring during the stressing causes a high level of dislocation defects existing in t…
A successful approach to improve organic photovoltaic cell performance is the introduction of a thin layer called the electron-blocking layer (EBL) at the interface organic material/cathode. Here, the effect of the EBL is discussed through the use of different multiheterojunction organic solar cells configurations. It…
Cells in a functional tissue display a highly interactive relation with their neighboring cells and associated biochemical milieu. Serious disruption in the existing homeostatic balance in the extra-cellular matrix (ECM) may lead to abnormal response by the cells. With insufficient understanding of Cell-ECM interactio…
用分子动力学模拟的方法研究了拉伸加载下位错在Fe/Ni界面的形核和发射过程。拉伸沿Fe[1 0 0]方向进行，平行于界面。由于晶格失配，系统弛豫后在Fe(0 0 1)/Ni(1 1 0)界面处会形成长方形的失配位错网络。模拟结果显示，当应变达到7.2%时，滑移位错首先在界面处失配位错线上形核，随着应变增加滑移位错向铁内部发射，而在镍内部并没有位错发射。当应变达到8.4%时，镍内才出现位错发射。在Fe基底中位错主要在{1 1 0}滑移面上滑移，而在Ni中主要在{1 1 1}滑移面上滑移。 Molecular dynamics simulations were carried out to investigate the nuclea…
A biocompatible packaging process for implantable electronic systems is described, combining biocompatibility and hermeticity with extreme miniaturization. In Phase 1 of the total packaging sequence, all chips are encapsulated in order to realize a bidirectional diffusion barrier, preventing body fluids from leaching…
Effect of thermal cycling on high temperature creep of thin-walled and coated CMSX-4 single crystal superalloy was evaluated by performing thermal cycling and isothermal creep tests at 1050C and 140 MPa, 1150C and 140 MPa and 1150C and 80 MPa. The deleterious effect of thermal cycling on the creep behavior and lifetim…
The effects of hammer peening and aging treatment on the near surface microstructure, mechanical properties, and corrosion resistance of oil-grade alloy 718, were investigated.Milling and hammer peening treatments were performed on the surface of alloy 718, followed by a double aging treatment.It was found that after…

In this paper a model for dielectric material in the formalism of Kluitenberg's theory on dielectric relaxation phenomena is proposed. The aim of the paper is to suggest a thermodynamic model with internal variable for dielectric isotropic material; in particular, by introducing the reciprocal complex dielectric susce…
We employed Ar–CH 4 to synthesize carbon nanosheets (CNSs), which are two-dimensional carbon nanostructures, by microwave plasma-enhanced chemical vapor deposition at relatively low temperatures and working pressures. The CNSs consist of few-layer graphene nanosheets with 1–3 nm thick sharp edges and possess a large a…
Epoxy based materials find a number of applications.Suitability of these materials demands the process of crosslinking, which among others influences the final mechanical and thermal properties.Raman spectroscopy is a modern research and analytical tool providing specific information of a molecular structure.Prime adv…
Different from the previous experimental and simulating methods, ab initio molecular dynamics simulations are performed to investigate the partial structures of liquid Ga, In and Ga-In alloys. In liquid Ga-In alloys, the positions of first peaks in gGaGa(r) and gInIn(r) are close to those of the pure Ga and In, respec…
