In dieser Arbeit wird NMR-Mikrobildgebung als neue Methode für die Untersuchung von schwerioneninduzierter Strahlenschäden in Kristallen eingeführt. Es wird ein Verfahren beschrieben, das es erlaubt Spin-Gitter Relaxationsratenprofile mit einer Ortsauflösung in der Größenordnung von 10 µm zu ermitteln. Wesentlich für…

During the transformer lifetime, existing problem in service regardless of the size and importance of the transformer, is the presence of water in the insulation system. Water as a polar molecule, negatively affects on insulating ability of material. Increase content (concentration) of water affects on the deteriorati…
A smart micro cantilever beam, consisting of an atomic force microscope probe bonded with a piezoelectric actuator, is proposed to enhance the ability of mechanical nanomanipulation. A precise three-section Euler-Bernoulli beam model is developed to describe the dynamics of the beam. The forced vibration solution of t…

Total Knee Arthroplasty (TKA) has been standard clinical practice for 25 years. During this time it has been extensively researched both biomechanically and in terms of its clinical performance as an implant (survival, compatibility, wear, complications etc). This research, which was often funded by the relevant comme…
Neuropeptide Y (NPY), a member of the neuropeptide Y family of hormones, was first isolated from porcine brain in 1982 (Tatemoto et al. 1982). The peptides of this family all contain 36 amino acid residues, are C-terminally amidated, and contain a rather high content of tyrosine, proline and arginine residues. NPY is…
以N,N-亚甲基双丙烯酰胺为交联剂,过硫酸钾-亚硫酸氢钠为引发剂,丙烯酸（AA）和2-丙烯酰胺基-2-甲基丙磺酸（AMPS）为单体,采用水溶液聚合法合成了丙烯酸-2-丙烯酰胺基-2-甲基丙磺酸-滤渣高吸水性树脂。考察了交联剂、引发剂、单体的质量比、AA中和度、反应温度、滤渣含量对树脂吸水率的影响。经正交实验制得的高吸水性树脂在24h内吸水达到饱和,吸蒸馏水1397g/g,自来水330g/g,0.225moL/L NaCl溶液79g/g。该树脂具有一定的耐盐性。

The analysis of clay mineral compositions for further classification on the basis of grades has been discussed earlier in this journal. This paper shows the fundamental statistical treatment of the compositional dataset that is required. It includes an analysis of the significance of the differences between compositio…
Microreactors are important alternative to conventional reactors in chemistry, chemical, pharmaceutical and semiconductor industries due to their operation characteristics such as increased mass and heat transfer, uniform flow, safety, high throughput through array configurations, smaller plant size and lower cost of…
The applications of quantum-well disordering technique to photonic devices have been studied in this work. This technique is utilized for reducing the waveguide losses and for improving the device performances. For the homogeneous microstructures, the bandgaps of active and the passive regions are the same, the emitti…
A crescente utilização de perfis metálicos de chapa dobrada traz consigo a necessidade de cálculos cada vez mais precisos e menos complexos, daí o surgimento de distintos métodos de cálculo e grande número de trabalhos acadêmicos sobre o assunto. Dentre os vários métodos, o método da Resistência Direta se mostra mais…
The chemistry and applications of carbon nanotubes are critically dependent on nanotube chirality. To date, no one has demonstrated chirality-selective synthesis of single-walled carbon nanotubes from pre-synthesized catalyst nanoparticles. A proposed chemical approach to the mass production of chirality-selective SWN…
AMPA receptors are ligand-gated ion channels that mediate excitatory synaptic transmission throughout the central nervous system.Two mechanisms regulating the activity of AMPA receptors are state-dependent channel block by intracellular polyamines and subunit-independent gating.Polyamine block of Ca 2+ -permeable AMPA…
Nanomaterials are well known to be used as reinforcing fillers. With its high surface area, addition of small amount of nanomaterials in the polymer matrix would increase the strength of the composite material. Carbon nanotubes (CNTs), carbon fibers (CFs) and carbon nanofibres (CNFs) are among the nanomaterials that a…

Abstract The molecule Hexachlorocyclotriphosphazene(N3P3Cl6) was seldom being applied in OLEDs. In our research, it was chosen to react with some simple aromatic compounds, such as pyrrole and indole, by general acid-base and Appel reactions, and then a series of materials with cyclotriphosphazene core were synthesize…
Line structures are an essential part in integrated circuit (IC) fabrication.In photolithography, the electromagnetic scattering of line structures is one of the main factors that determine the advancement of the technology node.From the perspective of modeling, a theoretical model to physically understand the scatter…
