Stent thrombosis and restenosis after drug-eluting stent (DES) implantation remains a relevant problem in the cardiovascular field. The polymer-based biomaterial (e.g. stent coating) requirements are comprehensive, since the polymeric material ideally should ensure an effective re-endothelialization by recruiting endo…
Nanostructured zinc films were prepared by electrodeposition onto templates of well-ordered regular arrays of PS spheres on ITO and gold coated glass substrates. The deposition was carried out from an ionic liquid (1-butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide) at room temperature in an argon filled…
Carbon Nanotube Field Effect Transistor (CNFET) has emerged as an alternative material to silicon for high performance, high stability and low power Static Random Access Memory (SRAM) design in recent years. SRAM functions as cache memory in computers and many portable devices. Therefore, CNFET based SRAM cell design…
Magnetic levitation technology has been receiving increasing attention because it helps to eliminate frictional losses due to mechanical contact. Some engineering applications include high-speed maglev trains, magnetic bearings and high-precision platforms. The objective is to model and control a laboratory-scale magn…
In this study, tin/tinoxide/multi oxide/multi walled carbon nano tube (Sn/SnO2/MWCNT) composites were produced by thermal evaporation and then subsequent plasma oxidation. Buckypapers having controlled porosity were prepared by vacuum filtration from functionalized MWCNTs. Pure metallic tin was thermally evaporated on…
The ability to quickly analyze, separate, and manipulate multiple types of biomarkers from small sample volumes is a significant step toward personalized medicine.
In order to investigate their electrical characteristics, high-voltage light-emitting-diodes (HV-LEDs) each containing four cells in series are fabricated. The electrical parameters including varying voltage and parasitic effect are studied. It is shown that the ideality factors (IFs) of the HV-LEDs with different num…
Gadolinium gallium garnet (GGG) polycrystalline powders doped with Nd,Yb were prepared by co-precipitation method. The structure, phase and properties of powders were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), energy dispersive X-ray sp…
The goal of the present work was to develop a lumped model for butyl acrylate emulsion polymerization based on the monodispersed particle size distribution assumption (all particles having the same particle size at a given time). The polymerization system that the model simulates consists of an isothermal and well-mix…
Abstract The use of eco‐materials on the basis of natural fibre reinforced polymer composites has found its way to many applications. In the automobile sector, the use of such composites has long been established for applications in the car interior. The use of natural fibre reinforced composites for braking applicati…
Paper-based material has been frequently used as part of packaging solution as an option towards reducing municipal solid waste generation. Various studies on mechanical behaviour of paper-pulp packaging material have been conducted based on the machining direction and cross machining direction. However, there is stil…
본 논문은 AUTODYN-3D 프로그램을 이용한 방탄 헬멧의 탄도충격에 관한 연구를 하였다. 두 가지 유형의 재료가 방탄 헬멧에 사용되었다. Kevlar 및 Steel/Kevlar 혼합복합재 이다. 강구와 7.62 mm 금속 피복탄이 시뮬레이션에서 사용되었다. 시뮬레이션에서 발사체의 변형된 형상과 내부에너지가 계산되었다. 결과는 Steel/Kevlar 헬멧을 관통하기 위해 요구되는 충격속도는 강구와 7.62 mm 금속피복탄에 따라 각각 655 m/s 와 845 m/s 이상이다. 결과로부터 Kevlar 와 Steel/Kevlar 헬멧 사이의 탄도 저항에 큰 차이를 볼…
ABSTRACT Bending and shear characteristics of bamboo–wood hybrid glulam (BWHG) beams were investigated to evaluate the possibility of using laminated bamboo lumber (LBL) as a lamstock for glulam beams in structural application. Moreover, two different resin types were also evaluated for bamboo–wood bond strength. Isoc…
Foi realizada uma revisão dos principais aspectos encontrados na literatura especializada sobre corrosão de refratários, avaliando-se a viabilidade de determinados ensaios e relacionando-os com os resultados experimentais. Na primeira parte deste trabalho foram abordadas as principais propriedades da microestrutura do…
An electrically tunable microwave resonator based on bilayers with single crystal Zn2Y-type hexaferrite and piezoelectrics of Lead Zirconate Titanate or Lead Magnesium Niobate - Lead Titanate is investigated. The resonator was positioned in a microstripline antenna structure based on alumina substrate. Resonance profi…
Abstract Hydrosilylation reaction of 2.4.6.8-tetrahydro-2.4.6.8-tetramethylcyclotetrasiloxane with allyl acetoacetate and vinyltriethoxysilane at 1:3:1 ratio of initial compounds in the presence of Karstedt’s catalyst (Pt2[(VinSiMe2)2O]3), platinum hydrochloric acid (0.1 M solution in THF) and platinum on the carbon h…
The heavy metals including Pb, Cd, Cr, As and Mn emission characteristics of coal-fired power plant boilers, industrial boilers, lead and zinc smelters, cement kilns, and steel industries were studied in this paper. The removing effects of heavy metals by pollution control technology were analyzed. ICP-AES method was…
The high-pressure behavior of zeolites of the stilbite-stellerite isomorphous series is studied by X-ray powder diffraction using synchrotron radiation in the penetrating (water-containing) medium in a high-pressure cell. At the initial stage (< 2 GPa), orthorhombic stellerite |Ca 3.77 (H 2 O) 28 | [Al 7.54 Si 28.46 O…
Ensaios de migração de cloretos são usados para mensurar a capacidade do concreto em inibir o ataque por cloretos. Muitos pesquisadores realizam esse ensaio em uma fatia de concreto extraída da parte central dos corpos de prova cilíndricos, descartando cerca de 75% do concreto usado para moldar os corpos de prova. Ess…
Abstract The distribution of organic matter in the genetic horizons of lateritic soil within a 100-cm profile to the basaltic parent rock is almost except for horizon Ap. Assuming that the sum of organic matter in 100 cm of the soil profile is 100%, 25.7% of these compounds occur in horizon Ap, whereas in the remainin…
