14C is a radionuclide of considerable interest in nuclear power production. Its \n5730 years of half-life and a big mobility in the environment make it present in ali \nparts of nuclear reactor primary system. \nFrom there it pass to the environment through gaseous and liquid discharges \nand through the disposal of r…
Due to their ubiquitous presence in hard-disk drives and growing potential as commercially viable memory bits, Magnetic Tunnel Junctions (MTJs) continue to provide impetus for scientific study. The demand for smaller devices and efficient energy consumption mandates further investigation of their thermal properties an…
A lattice defect model of kink deformation in magnesium alloywith LPSO structure is proposed from the point of view of anequivalence of wedge disclinations dipole and edge dislocationarray. Then, an interaction between isolated dislocation (withdifferent positions) and kink boundary (with different models) isstudied.…
In this study, we found that the local density of states and ionization energy spectrum of the valence electrons of methylnitrene (NCH 3 ) adsorbed on Cu(110) can be calculated from molecular orbital calculations of a simple artificial isolated NCH 3 –Cu 2 molecular cluster in which the two Cu atoms form bonds to the…

Radiotracer isotopes 131I and 82Br were used to study the iodide and bromide ion-isotopic exchange reactions taking place in two anion exchange resins Duolite ARA-9366B (nuclear grade) and Duolite A-638 (non-nuclear grade) under different operational parameters like temperature and ionic concentration of exchanging me…
Carbon nanotubes (CNT) are the fantastic nano-material which exhibits a very low thermal expansion and high current capability. It has a wide variety of methods for synthesis. One of the most reliable and best suited is Arc Discharge method. Multi walled CNT (MWCNT) are synthesized in an experimental setup. Soot depos…
Abstract To improve compatibility of multi-walled carbon nanotubes (MWCNTs) with polymer matrix, chloride-functionals were applied to the MWCNTs by functionalization using HNO3/H2SO4 and thionyl chloride. The MWCNTs were conjunct by poly vinyl alcohol (PVA) surface via ionic mechanism using benzoyl peroxide (BPO) in w…
Two novel polymers exhibiting metal-organic frameworks (MOFs) have been synthesized by the combination of a metal ion with a benzene-1,3,5-tricarboxylate ligand (BTC) and 1,10-phenanthroline (phen) under hydrothermal conditions. The first compound, poly[[(μ4-benzene-1,3,5-tricarboxylato-κ(4)O:O':O'':O''')(μ-hydroxido-…

运用ISSR标记对来自深圳、北海和防城港的三个细基江蓠繁枝变种群体进行遗传多样性检测，筛选出的16条ISSR引物共扩增出111条带，引物平均多态位点比例为54.95%。三个群体的多态位点比例深圳群体最高为23.42%，北海群体最低为4.50%；群体平均多态位点比例为11.12%，平均基因多样性(Hs)为0.051 3，表明细基江蓠繁枝变种群体遗传多样性较低。群体遗传分化指数为0.756 5，说明遗传变异主要存在于群体间且群体间的遗传分化水平较高。Mantel检验发现遗传距离与地理距离无关。适应生态环境选择无性繁殖模式可能是细基江蓠繁枝变种群体遗传多样性较低、群体间遗传分化大的重要因素。
In an actual oil spill situation, several factors are at play. This chapter describes the fundamental factors in hydrocarbon-water dispersions. The introduction, a brief account of different structures encountered in such systems, is followed by a description of some essentials of spontaneous emulsification and finish…
This chapter presents formulations of electromagnetics problems with surface integral equations. Surface formulations are derived for three-dimensional metallic, dielectric, and composite objects with arbitrary geometries. Various stabilization procedures are discussed for accurate solutions of low-contrast dielectric…
Dopamine is a neurotransmitter involved in motor, reward, and cognitive functions. Model systems are useful for studies of dopamine-related diseases, such as Parkinson's and schizophrenia. Drosophila melanogaster is a convenient model organism because it has homologous neurotransmitters with mammals and is easy and fa…
Algorithmics of motion is a fundamental part of robotics. It deals with the development of methods to compute, simulate and analyze motions of physical systems such as articulated mechanisms or mobile robots. Nevertheless, these methods can be applied to other problems beyond robotics. Indeed, a significant part of my…
Nonlinear electromechanical and polarization switching behaviors of piezoelectric materials and viscoelastic nature of polymers result in the overall nonlinear and hysteretic responses of active polymeric composites. Understanding the nonlinear behavior of the active polymeric composites is crucial in designing struct…
The evidence for the neurotoxicity of nanoparticles is summarized. The sources of such particles and the ways in which they may enter the brain are listed and discussed. These include the olfactory pathway, the respiratory tract, and the possibility of transport across the blood–brain barrier. However, nanoparticles a…
In this chapter, a new mechanism based on the research performed by Wasan, Nikolov, and their co-workers, is presented for the removal of contaminants from solid surfaces. The surfactant micelles (or nanoparticles) form two-dimensional (2-D) layered structures (caused by the entropic affect) in the three-phase contact…
