Interfaces in thin film/substrate systems play a central role in the performance of electronic devices in nano/microelectronics. However a detailed microscopic knowledge of the structure and composition of an interface is usually not established. Medium energy ion scattering (MEIS) is a powerful technique in interface…
Bulk metallic glasses exhibit potential applications as structural and functional materials due to their excellent mechanical properties, high wear resistance, good corrosion resistance for many glassy alloys, and promising magnetic properties. Most existing and potential applications of metallic glasses entail elasti…
Οι ζεόλιθοι ανήκουν στα νανοπορώδη υλικά ή αλλιώς και μοριακά κόσκινα. Βρίσκουν δε εφαρμογή σε πληθώρα εφαρμογών, καλύπτοντας ένα μεγάλο θερμοκρασιακό φάσμα. Η γνώση της απόκρισής τους κατά τις μεταβολές της θερμοκρασίας είναι καθοριστικής σημασίας για την αποδοτικότητά τους, ακόμα περισσότερο όταν εμφανίζονται ανώμαλ…
由使用密度矩阵重正常化组技术，充满一半的扩大哈伯德模型的阶段图被调查。常规顺序参数，二地点的纠纷熵，和块块纠纷熵详细被分析。根据数字结果，在弱联合区域，一个中间的 bond-order-wave (鞠躬) 阶段被显示在 charge-density-wave (CDW ) 和 spin-density-wave (SDW ) 阶段之间确实存在。批评阶段转变点被二地点的纠纷熵的第一顺序衍生物的奇特决定。在强壮的联合区域，直接阶段转变从 SDW 阶段发生到 CDW 阶段，并且出现不连续(第一份订单) 特性与精力水平交叉伴随了。阶段图由一些以前建议了的数字结果支持写作 Sengupta 等，(2002 ) ；Sandvik 等，(200…
The present article considers the results of research the process of ozone generation in the barrier discharge in ozonizers with high-resistance electrodes. These studies are based on previously obtained the representation of the temporal structure of the barrier discharge, namely the characteristic the current of a s…
Electrical machines are increasingly being employed in electric drives, among other things in car industry (ecological cars) and aerospace sector. In these drives, in order to increase the dynamics of the electric drive moment of interia should not be a large value. The mass of motor is one of the factors influencing…
In the report results of researching the tribotechnical properties of composites on a basis of resin, containing the nanopowders of various materials are resulted. Properties of nanocomposites in various conditions of a friction are shown.
采用基于密度泛函理论的第一性原理赝势平面波方法,研究过渡族多组元碳化物TixV1-xC的结构、稳定性及弹性性能。结果表明：TixV1-xC的晶格常数随着V的增多而线性递减;TiC晶体中掺杂V后导致力学性能发生变化;与TiC相比,Ti0.5V0.5C具有较大的体模量和最大的弹性系数C44,表明Ti0.5V0.5C具有比TiC高的硬度,但Ti0.5V0.5C的脆性最大;Ti0.5V0.5C具有最小的形成能,表明Ti0.5V0.5C最稳定。
Silicon has long been considered as one of the most promising anode material for lithium-ion batteries. However, the poor cycle life due to stress during charge/discharge cycling has been a major concern for its practical applications. In this report, novel Si-metal nanocomposites have been explored to accommodate the…
On cylindrical waves in anisotropic Cartesian materials and its implications on the harmonic mode separability assumption
Organic magnetoresistance is a phenomenon that is exhibited by many organic semiconductors.The resistance can change by more than 10 % at room temperature and as little as 10 milli-Tesla (mT) applied magnetic field.The change can be either positive or negative, and is angle invariant with respect to magnetic field ori…
Students have a comprehensive overview of high performance materials for aerospace ap-plications, which includes the well introduced materials and material systems as well as new developments and visionary concepts. They understand how materials and material systems are designed to be ‘light and reliable’ under extrem…
Abstract The properties of composite materials are closely related to the microstructure of the fibers or particles, matrix, and interfaces that can be studied, thanks to the use of a high resolution electron microscopy (HREM). It represents, in fact, one of the most powerful methods that can be used to clarify the mi…

Low photo- and water-resistance is often cited as the problem of MDI-based WBPU. This study addressed this problem. Water-borne poly(urethane-urea)s (WBPUs) were synthesized using a pre-polymer mixing process from 4,4'-methylenebis(phenyl isocyanate)(MDI)/4,4-dicyclohexylmethyl diisocyanate (H12MDI) (15/85 mole %)/dim…
The collective modes (longitudinal and transverse phonon frequencies) in binary metallic glass Cu50Zr50 have been studied in terms of eigen frequencies of localized collective excitations. Model potential formalism along with the Hubbard‐Beeby approach has been utilized to compute the phonon frequencies in the glassy…
i The rheological properties at liquid-liquid interfaces are important in many industrial processes such as manufacturing foods, pharmaceuticals, cosmetics, and petroleum products. This dissertation focuses on the study of linear viscoelastic properties at liquid-liquid interfaces by tracking the thermal motion of par…
Under drug selection pressure, emerging mutations render HIV-1 protease drug resistance, leading to the therapy failure in anti-HIV treatment.Tthe multidrug-resistant 769 (MDR) HIV-1 protease (resistant mutations at residues 10, 36, 46, 54, 62, 63, 71, 82, 84, 90) is selected for the present study to understand drug r…
The investigation of complexes in the solid state has developed exponentially over the past few decades in terms of both crystal engineering and supramolecular chemistry. The preparation of new metal-organic frameworks and coordination polymers has been of particular interest due to the large variety of structural top…
The goal of this work is to demonstrate the feasibility of end-to-end ("atoms to applications") technology modeling. Two different technologies were selected to drive this work. The first technology is carbon nanotube field-effect transistors (CNTFETs), and the goal is to model device level variability and identify th…
