The topography of mica surface after treatment with silane coupling agent having a mercapto group was studied using an atomic force microscope. The cleaved mica plate was used as a model inorganic surface. The effect of treatment condition on the topography of the mica surface was investigated. Agglomerates consisting…
A definitive, quantitative investigation has been performed to determine whether orbital atherectomy gives rise to cavitation. The investigation encompassed a synergistic interaction between in vitro experimentation and numerical simulation. The experimentation was performed in two independent fluid environments: 1) a…
With a view to examine the axial crushing behavior of thin-walled structures, which are used as energy-absorbing components of transports under various dynamic compressive loads, some thin-walled circular and regular polygonal tubes were investigated mainly by the FEM simulation. The former examination was focused on…
In this paper finite element simulation and neutron diffraction measurements are employed to assess the residual stresses in an AISI 316LN austenitic stainless steel plate containing a three-pass finite length weld in a machined slot. This work forms a part of the Task Group 4 (TG4) measurement and simulation round ro…
CoCl2 was treated with 1, 2, and 6 eq. of 2,6-bis(5-phenylpyrazol-3-yl)pyridine (H2L) yielding respectively the monosubstituted [Co(H2L)Cl2], the disubstituted [Co(H2L)2][PF6]2, and a supramolecular assembly formed by a central disubstituted octahedral complex and four more hydrogen bonded peripheral ligands, [{Co(H2L…
Our aim in this paper is to study a doubly nonlinear Cahn-Hilliard-type system. In particular, we prove existence and uniqueness results and the existence of global attractors.
The sensor properties of In 2 O 3 · SnO 2 polycrystalline films having different compositions were studied in the detection of 2% hydrogen in air over the temperature range 330–530°C. Films containing 19% In 2 O 3 were most sensitive to hydrogen. The temperature dependence of the sensitivity of sensors passed a maximu…
Under special circumstances a fast propagating crack can be triggered in pipelines by just a small local damage. In order to assess the safety with regard to this type of catastrophic failure, an analytical model was established to describe the process of large ductile tearing mathematically. Using a simplifying kinem…
Contrary to the overall trend in the worldwide economy, 2009 actually has turned out a good year for the physica status solidi journal series. With more than 10.000 published pages, pss (a), pss (b), pss (c), and pss (RRL) continue to be major players on the stage of journals covering the entire broad spectrum of soli…
Fuel cell is the technology that, nowadays, is deemed having a great potential to be used in supplying energy. Basically, fuel cells can be categorized particularly by the kind of employed electrolyte. Several fuel cells types which are currently identified having huge potential to be utilized, namely, Solid Oxide Fue…
Recent demands for cheaper and more compact devices require electronic devices to have more added in printed circuit boards. To meet these demands, smooth copper foils that enable finer copper wiring has need to be fabricated. For achieving such wiring, the effect that the initial deposition of copper on a titanium ca…
The chemistry of molecules displaying novel topologies has experienced an explosive development in the course of the last 25 years. The fast growth of this field originates to a large extend from the new templated synthetic methods which allow to prepare these compounds at a real macroscopic level. Our group, in parti…
We report on the photophysical and photovoltaic properties of a low band gap polymer bearing a quinoxaline moiety, poly(2,3-bis(3,4-bis(decyloxy)phenyl)-5,8-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)quinoxaline) PDOPEQ, as an electron donor in bulk heterojunction solar cells blended with the acceptor 1-(3-methoxyca…
激光冲击后在其金属表面形成一定形式的残余压应力,可对材料表面进行改性处理。采用ABAQUS有限元软件,研究激光功率密度、光斑形状对板料表层残余应力场分布的影响,探索残余应力场机制。结果表明,提高激光功率密度可以增加板料表层残余应力场,但随功率密度增大会产生＂残余应力洞＂现象;激光冲击后材料位移和表面应力动态响应分析表明,材料表面受冲击与材料弹性力作用产生振荡过程,冲击光斑边缘产生反射波（稀疏波）的反向加载,引起反向塑性变形,形成＂残余应力洞＂现象;光斑形状影响稀疏波向中心汇聚,造成中心残余压应力不同的缺失。该研究为工艺参数优化,减少冲击中心残余应力缺乏,获得更好的激光冲击处理强化效果提供依据。
The paper presents the methodology of determination of the stress di-stribution in post-critical state of deformation of the rectangular plate weakened with the crack subjected to tension. The problem was formula-ted as physically and geometrically non-linear. Using the finite elements method, numerical analyses were…
Recent advances in nanotechnologies stimulate the development of sensor systems based on nanocomposite materials. This review discusses the prospects and challenges of sensors coupled with functionally important for medicine hemoproteins and nanoscale materials.
