The 'molten globule' state has been regarded as an intermediate state between the native and denatured state of globular proteins. However, thermodynamically, the molten globule state is generally considered a denatured state, although, some notable exceptions have been reported. At pH 2, ovalbumin possesses fea- ture…
Biomass is a renewable and carbon neutral resource, because it can fix carbon dioxide from the atmosphere by photosynthesis. Recently, it is getting more attractive as alternative fuel resources from the viewpoint of global warming mitigation and fossil resource saving. However, in Japan, biomass resources are very li…
This paper presents size reduction of primary iron core for tubular linear induction motor by improved winding configuration. Using one-ampere conductor method, magnetic field analysis of tubular linear induction motor for size reduction is conducted. Size reduction and improvement of air gap flux distribution is achi…
Abstract Zur Modellierung des Verschleißverhaltens von Schneidwerkzeugen bei der Zerkleinerung polymerer Werkstoffe werden die dominierenden tribologischen Prozesse unter Verwendung der Diskreten Elemente Methode (DEM) untersucht. Die hierzu benötigten Wechselwirkungsmodelle der Einzelpartikelkontakte werden aus dem m…
실리카흄과 이산화티타늄을 건식 및 습식방식에 의해 나노화하여 시멘트 모르타르의 강도특성실험을 수행하였다. 실험변수는 건식 및 습식 방식으로 제조된 혼화재를 각각 5,10,15,20%의 첨가율로 하였다. 그 결과 실리카흄과 이산화티타늄을 사용했을 때의 시멘트 모르타르 강도 특성이 유사하게 나타났으며 건식과 습식 혼화재의 비교에서는 습식 혼화재를 사용했을 때가 더 큰 강도 특성을 보였다. Strength properties of cement mortar was carried out silica fume(SF) and Titanium Dioxide( $TIO_2$ ) b…
The bubble oscillations play an important role in ultrasonic cleaning processes. In the ultrasonic cleaning of semiconductor wafers, the cleaning process often damages micro/nano scale patterns while removing contaminant particles. However, the understanding of how patterns in semiconductor wafers are damaged during u…
Abstract The crystal structures of compounds (III) and (IV) are characterized by single crystal XRD.
Abstract Im Oktober berichteten wir über die Synthese und Untersuchung eines viergliedrigen Kohlenstoffrings, der offenbar sowohl die quadratische, nach der Hückel‐Regel anti‐aromatische Konformation als auch die rechteckige Form mit lokalisierten Doppelbindungen annahm. Zwei Zuschriften, die nun in Science erschienen…
This work focuses on the behavior of the overpotential increase due to a utilization rise in a molten carbonate fuel cell. The behavior is generally explained by Nernst loss, which is a kind of voltage loss due to the thermodynamic potential gradients in a polarization state due to the concentration distribution of re…
Abstract The title compound is synthesized from an aqueous solution of AgNO3, (NH4)6[H2W12O40], NaOH, and nicotinic acid (pH 3.1, 80 °C, 1 h, 34% yield).
본 연구는 자동차 내장 부품에서 표피재에 열을 가하여 금형내에서 엠보싱을 생성하는 새로운 압착방법을 제안한다. 엠보싱 무늬가 없는 표피재를 상부 금형에서 진공으로 흡입시켜 흡입력에 의하여 무늬를 성형한 후 금형을 닫아 사출물에 압착시키는 가열 압착 공법으로 엠보싱 무늬의 손상을 방지할 수 있다. 이 검증실험을 위하여 금형과 시험장치를 개발하여 시작품을 제작한 후 실험을 통하여 성능을 분석 평가하였다. This study proposed the new pressing method under heat for the plastic automotive interior pa…
When epitaxially grown on silicon carbide, a single layer graphene will exhibit a finite energy bandgap like a conventional semiconductor, and its energy dispersion is no longer linear in momentum space in the low energy regime. In this paper, we present a quantitative analysis on the effect of the SiC substrate in th…

Abstract The electrical transport properties and phase transitions of CdS were investigated under high pressure and moderate temperature by a microcircuit fabricated on diamond anvil cell. Around 2.0 GPa the resistivity of CdS dropped two orders of magnitude sharply, implying a beginning of a phase transition from wur…
The recent efforts to understand self-assembly of 'soft' photonic colloidal crystals in intrinsic disclination networks of body centered and face centered cubic lattices of blue phases I and II are briefly reviewed. © 2011 Photonics Society of Poland.
Abstract The title compound is prepared from a CeZnSn precursor (obtained by induction melting of the elements in a sealed Ta ampule) upon hydrogenation at 553 K and 4 MPa H2.
Abstract Pb2MnO4 and Sr‐doped Pb2MnO4 powders are synthesized by a polyesterification reaction based on the Pechini process using metal nitrates, citric acid, and ethylene glycol as starting materials.
We have studied the $TiO_2$ doping effects on the flux pinning behavior of an $MgB_2$ superconductor synthesized by the in-situ solid-state reaction. From the field-cooled and zero-field-cooled temperature dependences of magnetization, the reversible-irreversible transition of $TiO_2$ -doped $MgB_2$ was determined in…
Single-crystalline SnO2zigzag nanobelts and straight nanobelts with triangular tip were synthesized by a simple Tin–water reaction method. The product was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman scattering and micro-photoluminescence spectroscopy to obt…
Sampling disturbance can often introduce considerable errors in the laboratory estimation of geotechnical properties of soils. Accordingly, it causes inappropriative results in analysing field behavior. Therefore, a screw plate load test, one of in-situ test technique, is developed in this study, because in-situ testi…
