We report on tailoring of magnetic properties of Fe-Co –rich glass-coated microwires. Main parameter that affects magnetic properties of glass-coated microwires is the magnetoelastic anisotropy that can be tailored either changing the composition of metallic nucleus or controlling the internal stresses. The internal s…
Ten new C3, 6-dibenzoylated thiosemicarbazone-chitosan derivatives (with two different molecular weights) were prepared. The purpose of this study was to further investigate the antioxidant activities of this series of derivatives and the relationship between the structure and their antioxidant behavior. In order to k…
연료전지는 에너지 생산문제를 해결할 수 있는 유망한 신 재생에너지원으로 조명되고 있지만, 비싼 백금촉매가격 및 상용화에는 부족한 내구성과 촉매활성 문제로 어려움을 겪고 있다. 최근, 백금촉매를 대체할 수 있는 비 백금 촉매를 개발하기 위한 연구가 진행되고 있다. 비 백금촉매 중에서 질소도핑 그래핀(N-Gr)은 백금촉매와 비슷한 산소환원반응(ORR) 촉매활성이 보고되었다. 그러나, 산소환원반응에 기여하는 N-Gr의 구체적인 구조는 밝혀지지 않았고 N-Gr에서의 산소환원반응 메커니즘에 대해서도 많은 연구가 필요하다. ⓒ 2015 DGIST
Introduction: Wound healing is a dynamic process that involves multiple cellular elements with the purpose of restoring the functionality of the injured tissue. Many factors can interfere with this process, making it complex. Laser and microcurrent are therapeutic strategies that optimize the repair process, but have…
Development of lasers revived the interest in alkali halides as materials for optical components. This led to the development of alkali halide-polycystalline materials for use as optical windows. But their uses are limited by their mechanical properties and stability in some cases. Hence there exists the need to stren…
Different nanoparticles commonly available and used for research purposes were added to human blood samples in very low concentrations. Various physical parameters of blood; Viscosity, Surface tension, Conductivity, Refractive index and Size of RBC have been studied with very simple techniques and low cost materials a…
Drawing on inspiration from nature, transient, dynamic interactions can encode function into synthetic materials. Reversible interactions, such as dynamic covalent chemistry and transient noncovalent interactios can provide mechanisms for a host of functional applications such as self-healing, malleability, and energy…
A variety of polymers are used in engineering and medical applications. Polystyrene is one of the most important commodity polymer widely used in technical applications. It has applications in household goods, packaging, automobiles and other engineeringapplications. Four fillers calcium carbonate, graphite, mica and…

In this paper the model of research of large deformations of solids of incompressible elastic materials is constructed. The incremental method is used. By linearization of a resolving equation the system of the linear algebraic equations is received. Numerical modelling is based on finite element method.
AbstractThe temperature dependence of dielectric properties and electrical conduction of Ca 5 Nb 4 TiO 17 ceramics were characterized in a broadtemperature range. A dielectric anomaly with strong frequency dispersion was detected in the temperature range 700–1010 1C. This dielectricrelaxation could be almost removed c…

The present work focuses on designing of genipin crosslinked nanoparticles of gelatin and evaluating water imbibitions capacity of nanoparticles under varying experimental conditions. The gelatin nanoparticles of different composition and sizes were prepared by microemulsion crosslinking method and characterized by di…
Mehr als 2.500 Physiker aus dem In- und Ausland waren bei der Frühjahrstagung der Deutschen Physikalischen Gesellschaft an der Universität Heidelberg zu Gast. Es ging um Fragestellungen aus dem Bereich der Atom- und Molekülphysik, der Quantenoptik und der Physik der Hadronen und Kerne. Einen thematischen Bezugspunkt b…
A rectangular microstrip patch antenna loaded with Split Ring Resonator (SRR) is presented in this paper. Initially a rectangular microstrip patch antenna is designed that resonates at 8.5 Ghz which is then miniaturized to the operating frequency of 5.2 Ghz(WLAN) by inserting slots in the rectangular structure. To obt…
