The solubilities of acesulfame potassium in pure solvents and mixed solvents were measured using a synthetic method. The laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. All data were measured at atmospheric pressure and temperatures ranging…
We investigated the magnetic anisotropic parameters and spin-wave relaxation of thin films of the ferromagnetic half-metallic Sr2FeMoO6 by ferromagnetic resonance technique. The resonance field and linewidth were recorded as a function of relative angle between applied magnetic field and crystallographic axes of the s…
3D periodic ordered metallic-nanostructure-based hybrid materials with alignment on the micrometer scale are fabricated. Self-assembly of diblock copolymers, combined with inorganic components synthesized in situ, guides the inorganic materials into local polydomain nanostructures. Subsequently, through application of…
To develop a whitening agent, cytotoxicity of the soluble collagen isolated from Todarodes pacificus (CIT) was evaluated. CIT tested for cytotoxicity on human dermal fibroblast (CCD-986sk) was exhibited very low cytotoxicity. Because tyrosinase is the key enzyme for melanin biosynthesis, the use of various tyrosinase…
Abstract The control of structure formation of polycarbosilane (PCS) synthesized from polydimethylsilane (PDMS) was studied. It was found that the molecular structure of PCS was strongly dependent on the reaction time and reaction temperature. Shorter reaction time or lower reaction temperature is preferred to produce…
Positively charged alpha-chymotrypsin (ChT) formed a 1:1 complex with negatively charged 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrinato iron(III) (FeTPPS) in phosphate buffer at pH 7.4 through electrostatic interaction. In spite of the large binding constant (K=4.8 x 10(5) M(-1)), FeTPPS could not completely inhib…
We analyze and propose a thin-film patterning method based on Kretschmann's attenuated total reflection (ATR) configuration where the surface plasmon mode and plasmon coupled waveguide modes coupled into a target photosensitive layer are generated. By analyzing stratified media with the help of extended transfer matri…
In the present investigation, a glassing process for galvanic waste (GW) incorporation with a high chemical stability is presented. Glasses with up to 50 wt% of galvanic solid waste by modifications in the basic composition of soda–lime–borosilicate glasses were prepared. After fusing at temperatures up to 1300°C, the…
Ionic complexes of linear poly(ethylenimine) ( l PEI ) and poly(allylamine hydrochloride) ( PAH ) with 3,4,5-tris( n -alkan-1-yloxy)benzoic acid [ (3,4,5) n G1-COOH, n = 8, 10, 12, where n is the number of carbon atoms in the alkyl tail) or 3,4,5-tris[(p-( n -dodecan-1-yloxy)benzyloxy]benzoic acid [ (4-3,4,5)12G1-COOH…
Abstract The particle formation process during the precipitation of barium sulfate from aqueous solutions of barium chloride and sodium sulfate was studied experimentally and numerically. Particle formation was examined offline and in situ on timescales ranging from 55 ms to 1 s. Precipitation experiments were perform…
Lowering lasing threshold based on the Förster-type energy transfer process has been studied in distributed feedback (DFB) lasers of cholesteric liquid crystals (CLCs) containing two dyes. We found that the lasing threshold in the energy transfer process was lowered to less than half of that in direct excitation proce…
An anodic alumina oxide (AAO) film with nano-roughening is added on the top window layer of AlGaInP light-emitting diodes (LEDs) to improve the light extraction of the device. The AAO film has a natural porosity to provide light scattering centers at the surface, allowing an increase of light emission intensity with n…
Purpose The purpose of this study was to investigate the heat and moisture transmission through different types of textile materials or material combinations used for male business clothing. Design/methodology/approach In this study, eight different material combinations, which simulate four‐layer male business clothi…
The virtual crystal approximation is applied to ${\mathrm{La}}_{1∕2}{\mathrm{Na}}_{1∕2}\mathrm{Ti}{\mathrm{O}}_{3}$ (LNTO) to account for the chemical disorder. The structural distorsions (tilt angles, interatomic bondlengths) are reproduced with a very good accuracy. Linear response calculations within this approxima…
This work shows that low charge density poly(p-phenylene-ethynylene)s (PPE-SO3Na-L and PPE-CO2Na-L), which feature sulfonate and carboxylate groups on every other phenyl ring, form aggregates in water, whereas high charge density poly(p-phenylene-ethynylene)s (PPE-SO3Na-H and PPE-CO2Na-H), which possess sulfonate or c…
The members of the CuMo(1- x)WxO4 series (0 < or = x < 0.1) undergo a first-order phase transition that can be induced by pressure application; the thermochromic properties of such a series have already been reported. The two polymorphic forms exhibit two distinguishable colors: green for the low pressure form (alpha)…
Guest-induced transitions from α and γ phases of syndiotactic polystyrene (s-PS) toward cocrystalline and nanoporous phases, and related guest-induced orientation phenomena, have been investigated by X-ray diffraction. Guests, being able to induce cocrystal formation in amorphous s-PS samples, are able to induce room-…
Abstract Photosensitive cycloaliphatic‐epoxy oligosiloxane was synthesized using a nonhydrolytic sol–gel reaction for the fabrication of thick and thermally stable microstructures with high aspect ratios. Its formation was confirmed by 29 Si and 1 H nuclear magnetic resonance spectroscopy, small‐angle neutron scatteri…
When emulsion inversion is produced by continuous stirring, from an abnormal water-in-oil-in-water (w/O/W) system to a normal water-in-oil (W/O) morphology, to create a very high internal phase ratio emulsion (water fraction fw >0.85), the main mechanism is the continuous inclusion of the initial W external phase as w…
Ga-substituted cobalt ferrite oxides show promise as high magnetostriction, high sensitivity magnetoelastic materials for sensor and actuator applications, but their atomic-level behavior is not yet well understood. In this study, the magnetic environments of the Fe atoms in Ga-substituted cobalt ferrite have been inv…
