This research is divided into two related topics. In the first topic, the synthesis and characterization of novel composite materials reinforced with MWCNTs by ring-opening metathesis polymerization (ROMP) is reported for two ROMP based monomers: dicyclopentadiene (DCPD) and 5-ethylidene-2-norbornene (ENB). Homogeneou…

New switches are being designed based on carrier spin, excitons, and other properties. Graphene is considered a strong candidate for many of these applications. New phenomena abound at nanoscale dimensions, and graphene is no exception. Quantum confinement impacts materials properties and measurement itself. Berry Pha…
Supramolecular chemistry involves the study of noncovalent interactions that take place between molecules. A supramolecule or host-guest complex is formed when a noncovalent binding or complexation event occurs between two such molecules. Hydrogen bonds, electrostatics, pi-stacking, hydrophobic effects, solvatophobic…
An International Thermonuclear Experimental Reactor (ITER) Implementing Task Agreement (ITA) on Magnet Safety was established between the ITER International Organization (IO) and the Idaho National Laboratory (INL) Fusion Safety Program (FSP) during calendar year 2004. The objectives of this ITA were to add new capabi…
Copolymers are macromolecules composed of linear or non-linear arrangements of chemically different polymeric chain parts. In most cases the different constituting blocks are incompatible, giving rise to a rich variety of well-defined self-assembled structures both in bulk and in selective solvents. These self-assembl…
In this study, detailed numerical works are carried out to investigate cladding and superimposed hydrostatic pressure on fracture in metals under tension by using finite element software ABAQUS/Explicit. It is concluded that both cladding and superimposed hydrostatic pressure delay void nucleation and void growth, whi…
Un procede de revetement plasma, recemment developpe sur un acier C40E, a ete etendu a un acier inoxydable 304L. Ce procede, alternatif au sablage, consiste en la pre-oxydation controlee sous CO2 du substrat pour former de la wustite Fe1-xO, puis a la mise en œuvre du depot d’alumine. L’excellente accroche du depot su…
Los oxidos de gadolinio y de ytrio dopados con europio (Gd2O3:Eu, Y2O3:Eu) presentan propiedades luminiscentes. Dichas propiedades mejoran con la utilizacion de materiales nanoestructurados, con geometria esferica y estrecha distribucion de tamano de particula. Ademas, las propiedades luminiscentes son favorecidas cua…
The field distribution over a split ring resonator is expanded into Floquet modes，revealing the fact that the evanescent floquet modes actually lead to the metamaterial resonance behavior. Transmission through metamaterials is examined for arbitrary incident wave. It is shown that the resonance happens in the transmit…
In this study, gradient and isocratic elution of 11 phenothiazine derivatives in the reversed-- phase systems controlled by chaotropic effect was compared. Potential applicability of the Chromsword software for retention data prediction either under isocratic or gradient conditions was studied. Simulations were perfor…
We report on the fabrication and properties of waveguides made from a new Chalcogenide glass; Ge11.5As24Se64.5. The highest nonlinearity ever in a glass waveguide is demonstrated and a range of non-linear processes explored.
본 연구에서는 분광타원분석법을 이용하여 최근 주목 받고 있는 microwave dielectric materials 인 BaSm₂Ti₄O 12 박막의 광특성을 0.92 ~ 8.6 eV 에너지 영역에서 분석하였다. 광역 에너지영역에서 측정이 가능한 Vacuum Ultra Violet spectroscopic ellipsometer 를 사용하여 시료의 광 스펙트럼을 측정 하였으며, 측정된 스펙트럼으로부터 BaSm₂Ti₄O 12 박막의 광 특성을 얻기 위하여 Tauc-Lorentz 분산 함수를 이용하였고, 고 에너지 영역대의 새로운 피크구조 (structure) 를 최초…
In autonomous capillary systems (CS) minute amounts of liquid are transported owing to capillary forces. Such CSs are appealing due to their portability, flexibility, and the exceptional physical behavior of liquids in micrometer sized microchannels, in particular, capillarity and short diffusion times. CSs have shown…
Herein, we report an optimal procedure for the preparative-scale synthesis of AB in high yields and purity from sodium borohydride and ammonium salts. The first systematic study of the transition metal-catalyzed methanolysis of AB, the isolation and characterization of the resulting borate salt, and recovery of AB has…
Potassium-promoted iron oxide is the primary catalyst for dehydrogenating ethylbenzene to styrene. Due to an increasing demand for saving energy, there is a strong incentive to operate the reaction at reduced steam/ethylbenzene molar ratio, since a large amount of steam is used in the process. However, the catalyst ex…
Resumen A partir de la aparición de la instrucción de hormigón estructural EHE-98, ha surgido una queja generalizada en el ámbito profesional. Dicha queja está fundamentada en que, con la aparición de dicha normativa, algunos elementos que anteriormente se diseñaban sin armadura de cortante, hoy la requieren. Dicho pr…
Asymmetric planar split‐ring structures (planar chiral metamaterials) are investigated numerically in the time domain. Resonant asymmetry in transmission, reflection and absorption for right‐ vs. left‐handed circular polarization (circular birefringence and dichroism) is observed. Distributions of current confirm the…
The article is related to the compressed air purification for the rolling stock problems. The mechanical method is described as a potential way of the compressed air cooling and purificating. The temperature field at the heat conducting surface engineer function equation is given in the article as well.
Phosphorescent iridium(III)-based complexes are experiencing a growing interest in a number of research fields. Aside from lighting and display technologies (i.e. OLEDs and LECs), they find use in various applications such as biolabeling, sensors, solar cells and water splitting. In particular, the opportunity to tune…
