Native structure based models are a broadly used technique in bio molecular simulation allowing understanding of complex processes in the living cell involving bio macromolecules. Based on energy landscape theory and the principle of minimal frustration, these models find wide application in simulating complex biologi…
An application of Schiffman `C' section based left-handed transmission lines for coupling enhancement of coupled-line directional coupler's is proposed. The higher nominal coupling of the directional couplers can be achieved by using two symmetrically placed coupled-line sections and two sections of uncoupled left-han…
In this paper, the process of two-hole dies extrusion oval aluminium tube simulation analysis is carried out by the Deform-3D software .The simulation includes blank shunt, welding and extrusion deformation process. Temperature and stress distributions of the extrusion deformation is obtained through the simulation. I…
Rare earth Y、Gd、Nd were added to improve the tensile strength, elongation, hardness and microstructure of AZ91D magnesium alloy in this study. The investigation had been undertaken by 8 GWU type resistance furnace, RGM - 50 electronic machine , Vickers ,etc. Results show that a moderate amount of composite adding rare…
The ultrafine-grain steel 10 obtained by equal-channel angular pressing at 200°C is investigated. The structural strength of the steel samples is analyzed, with tensile tests and assessment of the impact strength and crack resistance. The strength of steel increases by a factor of 2.5 after equal-channel angular press…
Digital Image Correlation is a non-contact optical technique for measuring the full-field deformation on the surface of a deforming specimen. The technique was initially used in quasi-static experiments, but with the development of high speed digital cameras is used also in dynamic experiments. This use of the Digital…
Abstract Presented are OTFT arrays fabricated from a high mobility organic semiconductor ink wherein the preferred TFTs are corbino‐type devices. As a direct consequence of the corbino design, the resulting TFTs have very high on/off ratios, typically > 10 7 coupled with very low off currents. This corbino approach de…
The investigations of carbons of varying degrees of metamorphism and prepared based on of them coal resin compositions were carried out. An effect of coal resin composition on the parameters of the formed porous structure of activated carbon was demonstrated.
This paper presents research on the development of technologies for highly filled building material of low flammability based on CMSW. An affordable and effective fire retardant. The studies assessing the effect of the proportion of components of the molding composition, compaction pressure when forming the product on…
The polar discontinuity[1]and electronic reconstruction at the interface of SrTiO3 and GdTiO3 leads to a unique high two dimensional electron gas (2DEG) of 3×1014electron/cm2[2], that is exactly half of the number of unit cells at the interface. The ability to modulate this high charge density could enable a new class…
Casting mono-crystalline technology, or also called quasi-monocrystalline technology, is regarded as a promising approach to fabricate low cost but high quality wafers. Although very high efficiency can be obtained with cells fabricated from wafers located at the bottom to middle position of the ingot, the defect dens…
Piezoelectric material which can be used as both sensor and drive is an important kind of smart material. Studies on piezoelectric materials are now the research focus and hotspots of smart materials which have achieved fruitful results. This article describes the working principle of smart piezoelectric materials, pr…
Water tree is a significant degradation mode of power cables with polymeric insulation. The authors proposed a new diagnosing method for locating water tree degradation. In its procedure, a DC bias voltage is applied for poling the water trees, prior to applying a sharp probing pulse for depolarizing and locating the…
Abstract Highly birefringent liquid crystals have been desired recently by many applications in visible, infrared and recently other spectral regions such as THz and GHz as a active medium for various devices fabrication. For the broad temperature range of the nematic phase mixture formulation several structurally dif…
A facile impregnation method under mild condition is designed for synthesis of highly dispersed Pt nanoparticles with a narrow size of 4–7 nm on nitrogen-doped carbon nanotubes (CNx). CNx do not need any pre-surface modification due to the inherent chemical activity. The structure and nature of Pt/CNx were characteriz…
Exfoliated and partially oxidized MoS2 nanosheets as a hole extraction layer for efficient and stable organic solar cells (OSCs) is reported on page 2319 by H.-I. Joh, and colleagues. Incorporation of a simply prepared MoS2 nanosheet by solution-processing into OSCs dramatically increases the cell efficiency and devic…
Nanoparticles have recently been investigated as a possible way to improve absorption of light in solar cells. The strong interaction of nanoparticles with light allows control over the propagation of light at the nanoscale and thus, the design of solar cells, in which the light is trapped in an active layer and effic…
MAPPER Lithography is developing a maskless lithography technology based on massively-parallel electron-beam writing in combination with high speed optical data transport for switching the electron beams.
