Calcium oxalate monohydrate (COM), a urinary stone has been formed by single diffusion gel technique. The grown crystal is analyzed by Fourier Transform Infrared Spectroscopy (FTIR). The spectrum reveals various vibrational modes characterizing particular functional group. The investigation confirms the existence of o…
Experiments of dynamic behaviors are carried out for sandstone specimens by split Hopkinson pressure bar(SHPB) equipment with confining pressure device at different confining pressures and different strain rates. The effects of strain rate on uniaxial dynamic compression strength and specific energy absorbency,as well…
Fabric and sewing thread is the basic raw material of apparel industry. Characteristic of the raw material influences the seam quality of the garment. The apparel designers are primarily interested in the raw material properties for high seam quality and consumer is mainly interested in appearance, comfort, and wearab…
近年，電子機器の高機能化・高性能化に伴い，信号処理速度の高速化が重要な課題の1つとなっている。通信分野においては多くの情報を受信するため，GHz帯の高周波が利用されている。一方，プリント配線板においては，信号伝播速度の高速化・高周波化に対応するため，配線板材料の特性として低誘電率・低誘電損失（低tand）および低吸湿性などが求められている。本検討では紫外線を照射することによって電気特性の優れたシクロオレフィンポリマーフィルムの表面改質を行い，表面平滑性を損なうことなく，密着性に優れた導電層を形成する手法について検討を行った。
In this study, we fabricated Fe nanofibers that had a high aspect ratio and were coated by an oxidation protection layer, because electromagnetic properties are affected by the aspect ratio and oxidized layers. PVP/Fe salt nanofibers were prepared by an electrospinning method using an optimized concentration of PVP so…
This paper reports lattice dynamical measurements of Cu1.8Se superionic conductor in the superionic α-phase at ambient temperature. Measurements of phonon dispersion curves were performed with the new triple-axis spectrometer, TAIPAN, at the OPAL reactor. We found that TA [100], TA [111] and TA1 [110] phonon branches…
Ixora coccinea Linn is a species of the genus Ixora, belonging to the family Rubiaceae. The present study reported the use of Ixora coccinea flower extract as an acid base indicator in different types of acid base titrations. The equivalence point obtained by the flower extract coincident with the equivalence point ob…
Series of early lanthanides heteroleptic complexes of doubleand triple-decker sandwich-type structure with tetra(15-crown-5)phthalocyanine [(15C5)4 PcH2] and tetrakis-meso-(4-methoxyphenyl)porphyrin [An4PH2] ([An4P] Ln[(15C5)4Pc] and [An4P]Ln[(15C5)4Pc]Ln[An4P]) are synthesized. It is found that the whole series of La…
Collagen is the most abundant protein of animal origin, comprising approximately 30% of total animal protein. There are at least 19 variants of collagen, named type I to XIX. Types I, II, III and V are the fibrous collagens. Type I collagen is found in all connective tissue, including bones and skins. It is a heteropo…
In order to improve polyhydroxyalkanoate (PHA) production, it is necessary to investigate and understand the kinetic growth profile of fermentable bacteria under various fermentation conditions. Modern determination methods can only give the amount and type of PHA monomers without other polymer information such as mol…
Here we are reporting the synthesis of Zn1–xSnxS (x = 0, 0.1, 0.2, 0.3) nanoparticles and their photoluminescence properties. Zn1–xSnxS nanoparticles were synthesized by using thiourea as a capping agent. All the samples were characterized by X-ray diffraction technique. XRD patterns show the particle size in the rang…
The purpose of this study was to characterize and optimize the different proportion of polymer ratios, stirring speed on microspheres produced by the solvent evaporation method of idarubicin, an anticancer drug. Proportions of ethyl cellulose and hpmc were subjected to measurement of morphology, mean particle size, pa…
This paper describes an unfolding motion of fabric in air using pinching slip motion. During the pinching slip motion, the weight of the fabric generates relative movement between the moving fingertips and the fabric. The moving fingertips can hook into the hem of the fabric during the unfolding motion if the appropri…
Photorelease and photoisomerization of trans-cinnamic acid in aqueous CTAB solutions induces a bulk solution viscosity increase and decrease, respectively, triggered by orthogonal irradiation wavelengths.
Molecular mechanics and molecular dynamics simulations have been employed to characterise the interactions between SWNTs and biocompatible amphililic derivatives of chitosan, namely N-butyl-O-sulfate chitosan (NBSC), N-octyl-O-sulfate chitosan (NOSC) and N-palmitoyl-O-sulfate chitosan (NPSC). The computational simulat…
Here we report a low-cost and "green" phosphine-free route for the size- and shape-controlled synthesis of high-quality zinc blende (cubic) ZnSe nanocrystals. To avoid the use of expensive and toxic solvents such as trioctylphosphine (TOP) or tributylphosphine (TBP), SeO(2) was dispersed in 1-octadecene (ODE) as a cha…
Cocconeis pseudomarginata W.Greg., Seminavis robusta Danielidis & D.G.Mann, Synedra gaillonii (Bory) Ehrenb. var. macilenta (Grunow) H.Perag., and Trachysphenia australis Petit var. rostellata Hust. from Bacillariophyceae were reported for the first time from Turkish coastal waters. Additionally, Synedra gaillonii var…
Purpose: The aim of this work was to evaluate the ability of a continuous repetitive corrugation and straightening (CRCS) technique in creating ultra fine grained copper-chromium strips as well as to determine the microstructure evolution and its influence on grain size refinement.
