There is analysis of reasons of WAG process efficiency reducing in case of collector with water-wet surface in this article. Theoretical principles analyzing of reducing was made. Results of WAG and SWAG processes laboratory investigation for collector with water-wet surface are given.
The neutron-induced fission cross section of 238 Pu was determined using the surrogate ratio method. The (n,f) cross section over an equivalent neutron energy range 5‐20 MeV was deduced from inelastic α-induced fission reactions on 239 Pu, with 235 U(α, α � f )a nd 236 U(α, α � f) used as references. These reference r…
Several molecular and structural changes, occurring as a result of intrinsic change and extrinsic damage, are seen in aging skin. The most pronounced transformations seen are vascular atrophy, decreased collagen and elastic fiber content, loss of hydration, as well as a disordered dermal matrix. Currently, it is diffi…
Silicon has been the material of choice in the semiconductor industry since the last 50 years.Silicon etching forms an essential step in the fabrication of micro-electro-mechanical-systems, more commonly known as MEMS devices.Advancements in silicon etching have made possible the era of integrated on-chip sensors.An i…
ICP-CVD 방법에 의해 제작된 SiOC 박막을 유전상수와 화학적 이동의 상관성에 대하여 조사하였다. SiOC 박막은 플라즈마 에너지에 의해서 해리작용과 재결합작용에 의해서 cross link 구조를 갖게 되는 Si-O 와 C-O 결합으 로 구성된 930~1230 cm-1 영역에서 혼합된 Si-O-C 주 결합으로 이루어졌다. C-O 결합은 1270cm-1에서 보여지는 Si-CH3 결합의 말단부분인 C-H 결합이 전기음성도가 큰 산소에 의해서 끌리는 효과로부터 만들어진 결합이다. 그러 나 Si-O 결합은 Si-CH3 결합이 분해되고 난뒤 2차 이온결합에 의해서 만들…
Anterior cruciate ligament (ACL) ruptures and tears are significant orthopedic problems that result in discomfort and limited mobility. Fully functional tissue engineered ligament replacements are promising alternatives to current graft choices for repair of ACL disruptions. The cell-based approach to construct engine…
The work focused on addressing four main objectives. The first objective was to quantify protein and amino acid substitution reactions. Michael addition reactions were used to modify the amino acids and protein. Amino acids alanine, cysteine, and lysine, and protein ovalbumin (OA) were substituted with different conce…
The numerical simulation of damage using phenomenological models on the macroscale was state of the art for many decades. However, such models are not able to capture the complex nature of damage, which simultaneously proceeds on multiple length scales. Furthermore, these phenomenological models usually contain damage…
Construction on European Nickel plc's Caldag nickel laterite project in Turkey is expected to begin in early 2011 following debt finance for the project to be finalized in November 2010. The company is also looking to raise funds of around $300 million through lenders.
The aim of the work is development of new compositions of aluminium alloys with refractory metals of transition group and cremnium due to range extension of alloying at usage of high speed of melts cooling.

Vanadium dioxide thin films were successfully prepared on soda lime glass substrates using the optimised conditions for r.f-inverted cylindrical magnetron sputtering. The optimised deposition parameters were fixed and then a systematic study of the effect of deposition temperature, ranging from 450 °C to 550 °C, on th…
Congratulations on October's special issue of Physics World on nuclear power, which makes clear that the arguments about nuclear energy (pp24–25) are not as black and white as many people think.
Periodic holes array perforated in gold film is used to convert the normal-incident infrared light to surface plasmon waves, which can excite the intersubband transitions in the quantum wells (QWs) and enhance the optical absorption.
The refraction of electromagnetic waves at the interface formed by an isotropic regular medium and a biaxially anisotropic gyrotropic medium is investigated. The existence conditions of negative refraction and the effect of the different medium parameters on the total reflection and total transmission for TE waves are…
In this paper, we demonstrate the sensitivity of base resistance by different tilt angle of deep body implant into the base of Vertical NPN bipolar transistors. The base resistance in the vertical NPN bipolar transistors shows a strong dependency on the tilt angle of the boron implant from the deep body. We are able t…
Enhanced photoluminescence emission from higher subbands of nanopore lattices compared to a quantum well is presented. Increasing pore diameter enhances the excited state emission implying reduced intersubband scattering rate, consistent with theoretical calculations.
In semiconductor, the reliability of interconnects is assessed through electromigration (EM) on specially-designed metal line and via test structures. There are different types of test structures and methodologies for qualification and process monitoring purposes. Packaged level constant current EM (PLR EM) test is a…
Various nanoparticles have recently been developed for diagnostic and therapeutic use owing to the advance of nanotechnology. Nanoparticles decorated with monoclonal antibodies which showed selective binding to the intercellular cell adhesion molecule (ICAM) on the substrate were modeled. We utilized a transport-react…
A collection of slides from the author's presentation is discussed. The topics include ultra low-CTE polyimide laminate sheet and its reliability test.
