석단회를 활용한 CLSM(Controlled Low Strength Material)의 적용성이 증가됨에 따라 본 연구에서는 경량기포 GLSM의 압축강도와 단위중량과의 관계에 초점을 맞추어 CLSM 재료에 관련된 기초연구를 수행하였다 일축압축강도는 구조물에 적용시 재굴착이 가능한지를 판단할 수 있는 기준이 되고 있으며 시험결과를 통해 경제성 및 효율성 굴착성 등을 판단할 수 있는 중요한 배합설계변수이다 그러나 CLSM의 일축압축강도는 새령 28일 기준으로 적용성을 판단하기 때문에 정량적인 일축압축강도값을 알기 위해서는 배합 후 일정시간이 지나야한다 본 연구에서는 저…
Previous activity tests of carbon and nitrogen co-impregnated photocatalysts (C and N-impregnated-TiO2) for environmental pollution controls were primarily performed in the aqueous phase to investigate the decomposition of water pollutants. This study examined the photocatalytic activities of C,N-TiO2 photocatalysts f…
Die organische Elektronik hat sich in den letzten Jahren aus den Forschungslaboren heraus zur Marktreife entwickelt. Displays aus organischen Halbleitern werden mittlerweile von Firmen wie Samsung in Mobiltelefonen verbaut. Auch organische Solarzellen versprechen künftig einen großen Markt vieler Produkte. Ziel der Be…
The use of biogas for electrical generation can be an attractive solution especially when integrated with high\nefficiency energy conversion devices such as fuel cells. H2S content in biogas as high as thousands of ppmv\nand, when using a single shift reformer, CO content of 2-3 %, are the main challenges in fuel cell…
Organic/inorganic hybrid materials such as core-shell hybrid nanocomposites have attracted great interest in automotive industry since they can be adjustable through the control of functionality of the components and exhibit markedly improved durability on outdoor weather and scratch. We have synthesized nano silica b…
Free programs for the maximum-entropy method (MEM) and three-dimensional visualization are introduced with emphasis on their applications to TOF neutron powder diffraction data. The importance of correcting for thermal diffuse scattering is stressed to improving the accuracy of results obtained by powder diffraction.
In classical differential topology and geometry, the double ech-de Rham complex for a good covering U of M corresponds to the single de Rham complex. When passing to noncommutative geometry on smooth manifolds (i. e. to noncommutative geometry of the algebra C 1 .M / of smooth functions on M ), the single Connes compl…
Fragestellung: Injizierbare Calcium-Phosphat Zemente (Ca-P) sind in der Orthopädie für die Versorgung von Knochendefekten weitverbreitet. Ihre Anwendung hängt von ihren mechanischen Eigenschaften bzw. ihrer Biokompabilität, Osteokonduktivität und Osteoinduktivität ab. Obwohl[for full text, please go to the a.m. URL]

This study presents a novel method to produce self-setting inorganic foams with unique setting time and pore structure. The combination of the particle-stabilized foams with Portland cement reaction leads to a macro porous ceramic material which can be shaped and consolidated at room temperature. The foam microstructu…
The present study explored the characteristics and the photocatalytic activities of S-doped TiO2 (S-TiO2) and N-doped TiO2 (N-TiO2) for the decomposition of gas-phase isopropyl alcohol, according to calcination temperatures. The characteristics of the prepared photocatalysts were determined using an X-ray diffractomet…

Ground states and magnetic excitations of spin-1/2 kagomé antiferromagnets (KAF) A2Cu3SnF12 (A = Cs and Rb) were investigated by the magnetic measurements and neutron scattering experiments. For A = Cs, the system undergoes antiferromagnetic phase transition at TN = 20K. On the other hand, for A = Rb, non-magnetic “pi…
This paper describes an approach to manufacture hierarchical composites from environmentally friendly materials by grafting cellulose whiskers onto regenerated cellulose fibers (Cordenka 700). Fourier Transform Infrared spectroscopy, Scanning Electron Microscopy and X-ray diffraction analysis were performed to verify…
Spectroscopy is the study of interaction of electromag-netic waves with matter. Among the various spectroscopic techniques present, we have used fluorescence and UV-Vis spectroscopy to investigate the structure property corre-lation of ferrofluid and colloidal graphane.
