Polyacrylamide(PAM)–semiconductor MS (M = Cd, Zn, Pb) nanocomposites with homogeneously well dispersed semiconductor nanoparticles in the polymer matrices were prepared by a novel in situ simultaneous polymerization–hydrolysis technique (SPH).
The adsorption kinetics of hen egg white lysozyme (HEWL) in the presence of NaSCN at pH 7.4 onto Si0.8Ti0.2O2 surfaces were measured by means of time-resolved optical waveguide lightmode spectroscopy (OWLS). The adsorption kinetics were characterized by the presence of a lag phase whose duration decreased with increas…
In this paper, we report successful extension of the solid-solubility limit of copper at the transition element site in the ${(\mathrm{B}\mathrm{a},\mathrm{L}\mathrm{a})\mathrm{Y}(\mathrm{C}\mathrm{u},\mathrm{F}\mathrm{e})}_{2}{\mathrm{O}}_{5+\mathrm{\ensuremath{\delta}}}$ phase of the double-perovskite ``0112'' struc…
In this study, we investigate the change in the magnetic properties of magnetostrictive Fe/sub 77.5/Si/sub 7.5/B/sub 15/ amorphous wires thinned by chemical etching focusing on domain structure. It is found that the re-entrant flux reversal characteristic is still maintained even in the wire chemically thinned to a di…
The organometallic compounds [4-O 2 NC 6 H 3 (2-CH 3 )N=NC 6 H 3 (5′-CH 3 )-2′-(η 5 -C 5 H 4 )Fe(η 5 -C 5 H 5 )] 1 and [Mo(Cl)(Tp An )(NO){NHC 6 H 3 (3-CH 3 )[N=NC 6 H 3 (5-CH 3 )-2-(η 5 -C 5 H 4 )Fe(η 5 -C 5 H 5 )]-4}] 2 {Tp An =hydrotris[3-(p-methoxyphenyl)pyrazol-1-yl]borate} have been synthesized, characterized an…
New metallophthalocyanines (M=Cu, Zn, Ni or Co) substituted in peripheral positions with four 11-membered triaza macrocycles are prepared from 1,4,7-tris(p-tolylsulfonyl)-1,4,7-triazaheptane and 1,2-dibromo-4,5-bis(bromomethyl)benzene or the corresponding anhydrous metal salt [CuCN, Zn(O2CMe)2, NiCl2 or CoCl2].
A bola-amphiphile surfactant, containing a carboxylic acid at one end of the molecule and a thiol at the other, was bonded to nanoparticles of amorphous iron. The bonding of both functional groups was verified by FTIR and XPS measurements. TPD measurements exhibited three temperatures at which molecules are removed fr…
Experimental solubilities are reported at 25.0°C for phenanthrene dissolved in 41 different organic nonelectrolyte solvents containing ether, carbonyl, hydroxy, chloro, amino, ester, methyl and tert-butyl functional groups. Results of these measurements are used to test the applications and limitations of expressions…
An unsymmetrical phthalocyanine derivative containing a single styrene unit, prepared using a mixed phthalonitrile cyclotetramerisation, can undergo free radical polymerisation to give well-defined polystyrenes in which the macrocyclic components aggregate even in dilute solution.
Many studies have described the role of monocyte-derived macrophages (MDM) in inflammation leading to atherosclerosis, a process in which alterations in the metabolism of cholesterol esters is well established. On the other hand, the mechanism of MDM activation in response to biomaterial surfaces is still not well und…
It is well known that almost 70% of energy of fuel is wasted as thermal energy in the case of gasoline engine vehicle. Utilizing the thermal energy to provide electric power for automobile instead of using the engine driven alternator, we can reduce the load for the alternator and save fuel. Thermoelectric generator c…
A simple process was developed to produce transparent MgO ceramics. In this process, magnesium hydroxide was initially precipitated by means of dropping an ammonium solution to a magnesium chloride solution in a glass (pyrex) beaker at about 100°C. The resulting precipitate was kept in the aqueous solution for 3h at t…
Fluminicola bipolaris is described based on a specimen found on submerged wood collected in a tropical river in the Philippines. The taxon is similar to species of Annulatascus, but differs in having ascospores with bipolar bifurcate or cup-like appendages. The structure of these appendages is unique and is illustrate…
Through investigations made on crosslinked polyethylene (XLPE) insulated power cables that had experienced failures, blue-colored water trees were observed in addition to ordinary white water trees. The blue water tree was found to be much more harmful than the white water tree, since more electrical trees started at…
Two new series of calamitic liquid crystals containing the isoflavone moiety within the central core have been prepared and their liquid crystalline properties studied. The compounds exhibit typical nematic, smectic A and C mesophases. The influence of the linking group between a terminal alkyl chain and the central c…
Well-defined spiro-polymers which are freely soluble in organic solvents can be prepared from the ketal-forming reaction between pentaerythritol and either a diketone bearing alkyl solubilising groups or a diketone which generates a contorted polymeric structure.
A spirobenzothiapyran derivative bearing a monoaza-12-crown-4 moiety affords significant thermal stability enhancement in the UV light induced colored merocyanine form of its photochromic moiety by metal-ion complexation of its crown ether moiety, although the complexation hardly induces the isomerization without phot…
The hydrogen permeation behavior of carbon steel (CS) was investigated electrochemically in weak alkaline solutions containing hydrogen sulfide (H2S) with various cyanide ion (CN–) concentrations under open-circuit conditions. Anodic and cathodic polarization behaviors of CS also were investigated under the same envir…
Two experiments were carried out to determine the effect of poly(3-hydroxybutyrateco-3-hydroxyvalerate) (PHBV) and polycaprolactone (PCL) inclusion (Exp. 1), and of PHBV pre- treatment with sodium hydroxide (Exp. 2) on the digestibility of diets in growing pigs. In Exp. 1, eight male castrated Large White pigs (initia…
An atomic-crystallographic mechanism is proposed for the α → ω transformation during irradiation. The mechanism is based on the propagation of a localized displacement wave of the [100]α close-packed rows. From the phonon dispersion curves along (010)α, the displacement wave is decomposed into two transverse optical p…
