Novel diphenylphenanthrenes (DPPs) were prepared by a photocyclization method, and the substituent effects of the phenyl groups on the photophysical properties of the phenanthrene chromophore were investigated based on measurements of fluorescence yields, lifetimes, and transient absorption. Fluorescence activities in…
The volume fraction of the single domain size particles can be directly estimated from the initial magnetization of thermally demagnetized magnets. Multi-domain grains present initial magnetization curve with high initial susceptibility, whereas single-domain grains present low susceptibility initial magnetization cur…
A novel electrochemical glucose biosensor was prepared by combining platinum nanoparticle doped Santa Barbara Amorphous Material 15 with glucose oxidase. The resulting material demonstrated high stability and reactivity for catalyzing glucose electrolytic oxidation, primarily due to the high surface area of these cata…
High performance nanostructured light metals and alloys are very interesting for replacing conventional heavier materials in many industrial components. High Energy Ball Milling and Cryomilling are useful techniques to obtain nanocrystalline powders. In this work the effect of several milling conditions such as rotati…
전세계적으로 희소금속의 중요성이 높아지고 있는 가운데 일본은 2004년부터 원소전략 개념을 도입하고 2007년부터는 원소전략사업을 추진하게 되었다. 일본의 문부과학성의 "원소전략 프로젝트"는 물질과 재료를 구성하고 그 기능과 특성을 결정하는 원소의 역할과 성격을 연구하고, 물질과 재료의 기능과 특성의 발현기구를 명확히 규명함으로써, 희소원소나 유해원소를 사용하지 않는 고기능을 가진 물질과 재료를 개발하는 것을 목적으로 하고 있다. 특히, 2010년 9월 일본명 센카쿠렛도(중국명 댜오위다오)에서 중국어선과 일본순시선이 충돌하는 사건이 일어나서, 중국어선을 나포하여 영…
Among the most interesting applications of ferromagnetic nanoparticles (NPs) in medicine is the potential for localizing pharmacologically or radioactively tagged agents directly to selected tissues selected by an adjustable external magnetic field. This concept is demonstrated by the application external magnetic fie…
본 연구에서는 조성이 52 Pd - 20 Ag - 15.2 Au - 6 In - 5.4 Sn - 1 Ga - 0.2 Pt - 0.2 Ru(wt%.)인 금속-세라믹 금관용 합금의 모의소성과 반복소성에 따른 합금의 경도와 미세구조의 변화를 관찰하여 다음과 같은 결과를 얻었다.BR 1. 용체화 처리된 시편은 기지를 이루는 Pd-Ag-based 상과 입자형 구조를 이루는 Pd3(In,Sn)상으로 이루어져 있으며, 이러한 두 상 구조는 전체 소성 과정 동안 유지되었다.BR 2. 탈가스 처리를 통한 경도상승은 Pd-Ag-based 상으로 이루어진 기지에서 Pd3(In,Sn)상…
The development of soil cover on volcanic rocks in Central and North Bohemia was analyzed. The study was performed in the protected landscape areas on basalt, andesite, and dolerite. Parent material was characterized on the basis of thin-section study. Petrography of the parent material makes it possible to document t…
this paper presents a split-ring resonator (SRR) which is a metamaterial microwave absorber structure. The structure is simulated in CST solver that giving rise to almost unity absorption at X band. Combining two different SRRs with two dielectric layers, at vertical direction, makes an expansion of the bandwidth of m…
Chemical reaction speed is frequently enhanced at a surface, particularly when materials like platinum are present. It is well known that porous materials such as sol-gel silicas, controlled pore glasses, templated porous materials such as SBA-15, MCM-41, MCM-48, and zeolites, offer large surface areas. This in turn m…

The analysis of the experimental peel test data for obtaining the adhesion fracture energy of an adhesively laminated polymer to the sheet metal surface is considered. The experimental results of the 180° peel test on two types of polymer laminated sheet metal at three different peel speeds are analyzed by two methodo…
The antiperovskite manganese nitride compound Mn3Ag1-xCuxN has a broad resistivity-temperature curve around room temperature that is comparable with the Manganin alloy. This curvature and the peak temperature can be adjusted by codoping with Cu and In or Fe. The drift rate of the resistance value was strongly affected…
Cu II -arginine coordination compound was synthesized and characterized by using DSC, DTA, EA, FT-IR, XRD, SEM and EDX analysis techniques and then the hydrogen storage properties were investigated. Hydrogen storage performance of synthesized compound was determined both experimental and theoretically by using Materia…
The effect of the substitution of La with Pr on the microstructure and some electrochemical properties of La0.7-xPrxMg0.3Al0.3Mn0.4Co0.5Ni3.8 (x=0.0, 0.1, 0.3, 0.5, and 0.7) ingot alloys as powder electrode was studied in this paper. XDR and SEM (+EDX) analyses revealed that the as-cast alloys consist mainly of simila…
Objective: Three different seaweeds were used for biosynthesis of iron oxide nanoparticles. The screening of seaweeds, and suitable conditions for iron oxide nanoparticle synthesis were analyzed using different optimizing parameters such as concentration of seaweed extract, reaction temperature, and pH. It was found t…
A complex of Fe(III) with 4-amino-5-(pyridyl)-4H-1,2,4-triazole-3-thiol was prepared and evaluated as a photodegradation for rigid poly(vinyl chloride) (PVC). Polyvinyl chloride dissolved with Fe(III) complex in THF solvent to form PVC films of 5% (40 μm) thickness containing different concentrations (0.01, 0.02, 0.03…
