The kinetic studies on solid residues after pyrolysis from ASR (Automobile Shredder Residue) originated from STENA Metall AB have been performed with the use of thermogravimetry analysis TGA. The char after microwave pyrolysis has been pyrolyzed and combusted in the presence of helium and air respectively. The TG expe…
一系列基于黄金的催化剂被免职降水或早期的湿受精在 CexZ1xO2 稳固的溶液(0.28x1.00 ) 上准备。这些催化剂的词法、结构的描述与 X 光检查衍射，传播电子显微镜学(TEM ) 分析和物理吸附技术被执行，并且他们的氧化还原作用性质被温度学习把 H2 和公司用作探查分子的规划减小。氧化 / 减小的二个周期被执行以便在氧交换能力上评估氧化还原作用老化和金 sintering 的效果。是与另外的高贵金属观察了，在更低的温度提高并且支持 ceria 减小的黄金。由公司的减小被显示依赖于黄金的好分散并且被变老的过程否定地与氢多于减小影响。这可能在象作为主要反应物包含公司的水气体移动和 CO-PROX 一样的反应有含意。
We apply a recently proposed density functional for mixtures of parallel hard cylinders, based on Rosenfeld's fundamental measure theory, to study the effect of length-polydispersity on the relative stability between the smectic and columnar liquid crystal phases. To this purpose we derive from this functional an expr…
的金属离子的替换在可见轻反应改变乐队结构和结果。在自然闪锌矿的杂质半导体和 nanosized 粒子的共存取样帮助延长电子洞对的一生。劈开飞机和破裂表面改进由比完成式提供更活跃的地点的自然闪锌矿的催化活动面对的相片。两个都，否定费用从非等电子的替换和表面元素背叛，可变化学原子价压制了由他们捕获后象的可能的角色的电子洞对的再结合评估了洞。
We study heat transport in a one-dimensional chain of a finite number N of identical cells, coupled at its boundaries to stochastic particle reservoirs. At the center of each cell, tracer particles collide with fixed scatterers, exchanging momentum. In a recent paper (Collet and Eckmann in Commun. Math. Phys. 287:1015…
存在古典塑造的费用为他们能够在金属性的目标完成大洞深度到洞直径比率的更长的喷气是众所周知的。处于一些状况，在那里然而产生为洞深度获得 1:1 比率到在塑造的正常以外的洞直径的需求收费能力。形状充电的新变体，命名 W 打了形状充电(WSC ) ，在这被建议纸，它能遇见 1:1 比率的需求，并且基于能在合适的开始计划之上生产环形的喷气的几何学。在这篇论文，我们现在的形成和穿入基于三个不同计划 WSC 结果。我们也证明并非所有 WSC 图案能形成环形的喷气，仅仅环状地开始的 WSC，它也完成“内部外部的班机相等推动”标准，有能力形成环形的喷气。试验性、数字的结果证明当在环形的开始戒指直径和费用直径之间的比率是 0.75 时，一口环形的喷…
和压力之间的关系，在高压力下面的有弹性的常数成功地被获得。特别，在高压力下面的钻石的有弹性的常数第一理论上被获得。同时，有压力 P 和温度巢菜的热扩大 α 的变化在 0 870 GPa 和 0 1600 K 的范围系统地获得了。

The ab initio electronic structure optimization and total-energy calculations are used to study the equation of state （EOS） and elastic properties of fcc aluminum at zero temperature. We use the calculated energy of a solid as a function of the molecular volume fitting to the quasi-harmonic Debye model to obtain the n…
Different parameters affecting the pressure drop of fluid flow through packed bed have been studied. These parameters are fluid velocity, bed porosity, bed diameter, sphericity, particle diameter, packing height and wall effect. A semi-empirical equation for water flow through packed bed has been proposed, which can b…
In recent years, the occurrence of primary water stress corrosion cracking (PWSCC) in Alloy 600 weld regions of PWR plants has increased. In order to evaluate the crack propagation of PWSCC, it is required to estimate stress distribution including residual stress and operational stress through the wall thickness of th…
CaCu3Ti4O12were prepared using conventional solid state reaction processing techniques of ceramic. The CaCu3Ti4O12crystalline phase was verified by XRD patterns. From SEM micrographs, obvious grain and grain boundary structures were observed, and the grain boundary region was comprised of small grains, which were foun…
The aim of this work was to obtain ceria-based catalysts with improved oxidation properties by adding tin dioxide (5, 10 and 20 wt %) and using the co-precipitation method of preparation.The samples were characterized by BET, ESEM, and DRIFT spectroscopy.The activity of SnO 2 -CeO 2 catalytic systems in CO oxidation w…
In this paper, seven constitutive models for oxygenfree high conductivity copper at high pressure and high strain rate are constructed based on Y/G=constant and on G/B=constant, respectively （Y denoting the yield strength, G the shear modulus, B the bulk modulus）. The variations of longitudinal stress, transverse str…
The structural size effect law with influence of nonlinear fracture mechanics is revisited with the new experimental programme on notched / unnotched, plain and reinforced Three Point Bend (TPB) concrete beam specimens using conventional instrumentation, acoustic b-value analysis and high resolution image processing s…

The degree of fresh produce safety obtained with the currently applied preservation methods seems to be not sufficient. The interest in the possible use of natural compounds to prevent microbial growth has notably increased in response to the consumer pressure to reduce or eliminate chemically synthesized additives in…

Two separate experiments were performed to test the biocompatibility of amphiphilic conetwork polymers for medical applications.In experiment 1, four different types of polymers were tested in the liver and brain of 20 rats to determine which polymer would be best suited for intervertebral disc repair or replacement.T…
Shape memory and superelastic applications of NiTi based alloys have typically been limited to near room temperature or to bulk length scales. The objective of this work is two-fold: first, to investigate shape memory behavior at low temperatures in the context of the R-phase transformation in NiTiFe alloys by recours…
