The Pd(II)-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (BINAP)-mediated chiral assembly of thioether-derivatised phthalocyanatomagnesium(II) compounds (MgPc(SR)8, SR is benzylthio (SBz) or benzhydrylthio (Bh)) was formed in toluene and at the toluene/water interface, and investigated by means of UV-Vis absorption and…
In the present work, thermal properties of praziquantel, including melting point phase diagram and solubility, were determined for the purpose of exploration on an integrated enantioseparation process of chromatography and crystallization. The solubility of racemic praziquantel in methanol and 2-propanol was measured…
A laboratory experiment with leaching columns reproducing the topmost portion (Ap and AB horizons) of a Palexerult from western Spain was conducted to compare the efficiency of limestone (L), gypsum (G), and various lime and gypsum by-products (sugar foam waste, phosphogypsum [PG], and red gypsum [RG]) to alleviate Al…
Current projects for the massive characterization of proteomes are generating protein sequences and, to less extent, three dimensional structures with unknown function. Experimentally determining functional features of a protein is expensive, time consuming and difficult to automate. There is therefore a demand for co…
The growth of anodic coatings on titanium, under sparking conditions, is investigated in tracer experiments, using alkaline silicate and phosphate electrolytes. Coatings are formed sequentially in each electrolyte, with phosphorus and silicon located by energy-dispersive X-ray analysis and glow discharge optical emiss…
Indole-3-acetic acid (IAA) activation by horseradish peroxidase (HRP) has been suggested as a new cancer therapy. Interestingly, we found that ultraviolet B UVB radiation also can activate IAA and produce free radicals in a dose-dependent manner. In this study, we attempted to identify the free radicals generated by U…
燃料電池の実用化に向けての水素の輸送・貯蔵方法の一つとして高圧水素ガスを用いる方法が挙げられる. 本研究では, 高圧水素ガスシステムで使用される材料の安全性評価を目的として, アルミニウム合金およびオーステナイト系ステンレス鋼の機械的性質を45MPaの高圧水素ガス中の低ひずみ速度引張試験 (SSRT, Slow Strain Rate Testing) により調査した. アルミニウム合金A6061-T6および安定化オーステナイト系ステンレス鋼である316L鋼は低ひずみ速度条件下 (3×10-7～3×10-6s-1) でも脆化を示さなかった. 一方, 準安定オーステナイト系ステンレス鋼である304L鋼は, ひずみ誘起マルテンサイト相…
The structures of the (5,5) single-walled carbon nanotube (SWCNT) segments with hemispheric carbon cages capped at the ends (SWCNT rod) and the Pt-doped SWCNT rods have been studied within density functional theory. Our theoretical studies find that the hemispheric cages introduce localized states on the caps. The cap…
TiO2 films have been deposited on bare glass and on glass coated with indium tin oxide (ITO) by the liquid phase deposition (LPD) method, using Al(III) nitrate and Fe(III) chloride as alternative fluoride scavengers. Films were characterized by grazing angle X-ray diffraction, scanning electron microscopy, UV-vis spec…
Before employing carbon nanotubes (CNTs) in a polymer matrix as potential reinforcement elements, major obstacles, like inhomogeneous distribution and formation of agglomerates, need to be removed. Transmission Light Microscopy is a very quick, cheap and useful tool for roughly quantifying such problems. In this paper…
The effect of doping potassium on the A-site of for application as a high-temperature proton conductor was investigated. The synthesis of K-doped and its characterization by X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray analysis is described. Potassium-doped material was stable at high w…
Dithiaethyneazuliporphyrin, the first contracted carbaporphyrinoid, has been synthesized; the molecule contains an azulene moiety embedded in the [18]dithiacarbatriphyrin(4.1.1) macrocyclic framework.
The polarization behavior of ( La 0.8 Sr 0.2 ) 0.9 Mn O 3 (LSM) electrodes in contact with different chromia-forming alloys including a Ni–Cr-based superalloy (R600), and ferritic stainless steels (RA446 and Crofer22 APU) was studied under solid oxide fuel cell (SOFC) operating conditions. The magnitude of the polariz…
PURPOSE: Normal tissue radiosensitivity is the major limiting factor in radiotherapy of cancer. The use of phytochemicals may reduce the adverse effects of radiation in normal tissue. The effect of ethyl acetate fraction of Aphanamixis polystachya (EAP) was investigated on the radiation-induced chromosome damage in th…
The kinetic behavior of the α-Ni 1-x S → β-NiS transition was investigated via a series of annealquench experiments using Rietveld quantitative phase analysis of powder X-ray diffraction data. Initial compositions of α-Ni 1-x S were found to play an important role in the kinetics of the transition. The activation ener…
Two heterotrinuclear complexes, [Mn(II)(Ni(II)L)2].2CH3OH (where H3L = 1,1,1-tris(N-salicylideneaminomethyl)ethane) and [Fe(III)(Ni(II)L)2]NO3.C2H5OH, consisting of three face-sharing octahedra have been prepared; although these complexes have closely related structures and have the same 1-5/2-1 spin system, they show…
Three-dimensionally ordered macroporous carbons were prepared from bimodal polymer-silica colloidal crystals; the resulting carbons had interconnected macropores, and the walls of the macropores were composed of hollow mesosized spheres.
Article The use of polyelectrolyte multilayers of cationic starch and CMC to enhance strength properties of papers formed from mixtures of unbleached chemical pulp and CTMP. Part I was published on January 1, 2006 in the journal Nordic Pulp & Paper Research Journal (volume 21, issue 1).
Photochemical Electron Transfer (ET) between an organic dye, the porphyrin derivative TMPyP, and an electron acceptor, methyl viologen MV2+, have been investigated at the interface of two different inorganic films, i.e., layered titania nano-sheets (TNS) and a monolayer film of spherical and mono-dispersed mesoporous…
