The effect of pore size on the gaseous adsorption of ethenzamide (EZ) on porous crystalline cellulose (PCC) in a mixture of PCC-EZ, and the physicochemical stability of EZ in a mixture of PCC-EZ after storage at various relative humidities (RHs) were investigated by powder X-ray diffractometry, differential scanning c…
A polarised neutron diffraction (PND) experiment on [Ru(acac)3] at 4.18 K and 5 T along the b and c axes yielded 28 and 17 flipping ratios respectively. Single-crystal X-ray structure determinations at 293, 92 and 10.5 K, together with powder neutron diffraction experiments, provided auxiliary data allowing magnetic s…
The electrochemistry of a µ-oxo dimanganese(III) octaethylporphyrin (II) and those of the corresponding mononuclear complexes MnIII(OEP)Cl (I), MnIII(OEP)ClO4 (III) and MnIII(OEP)OH (IV) (where OEP represents octaethylporphyrin) were studied. When complex II was adsorbed on an electrode and placed in aqueous acidic el…
3%Si–Fe (100)[011] single crystal was investigated to analyze its texture evolution during rolling and recrystallization. Cold rolled (100)[011] could be fully recrystallized by utilizing dynamic strain aging, and sharp recrystallized texture was obtained. Rolled texture maintained the initial orientation (100)[011] w…
Impact experiments have been performed to obtain shock compression, release response, and spall strength of two scaled concrete formulations. Wave profiles from a suite of ten experiments, with shock amplitudes of 0.08 to 0.55 GPa, focus primarily on the elastic regime. Despite considerable wave structure that develop…
Calcium carbonate has been modified with three surface modifying systems based upon stearic acid, acrylic acid and a reactive coating comprising acrylic acid with dicumyl peroxide through dry blending. Polypropylene homopolymer was compounded with the coated and uncoated fillers (0 to 65 wt%) through twin screw extrus…
Since ω-phase crystals in β-Ti alloys formed by aging become nucleation sites of α-phase crystals due to further or high temperature aging, it is thought that this phenomenon can be utilized to produce stronger and more ductile (β+α) duplex Ti alloys. In order to form high density ω-phase crystals, the effects of a st…

In this note we apply some theoretical predictions that arise in the mean field framework for a large class of infinite range models to structural glasses and we present a first comparison of these predictions with numerical results. 1 Introduction In recent years some theoretical progresses in our understanding of gl…
A review is presented of the current research and development of shape-memory materials, including shape-memory alloys, shape-memory ceramics and shape-memory polymers. The shape-memorymaterials exhibit some novel performances,such as sensoring (thermal, stress or field), large-stroke actuation, high damping, adaptive…
453-623Kの広い温度範囲で高温・高圧のメタノールによるポリエチレンテレフタレート (PET) の加溶媒分解反応の速度定数を決定した. その結果, 臨界温度 (512.6K) 以下のメタノールによる分解の速度定数と, 臨界温度以上のメタノールによる速度定数のArrheniusプロットを同一直線で表すことができることから, 両領域のメタノール間の反応性の差はおもに温度によるものであり, 劇的な変化がないことが明らかになった. 一方, 今回検討した臨界温度以上のメタノールによるPET分解反応に比べて従来の約453Kでの液体メタノールを用いる分解反応速度がかなり遅い理由は, 従来法ではメタノールの蒸気圧が2.7MPaと低く, さらに…
Dc magnetization and ac magnetic susceptibility have been measured in the temperature range 80–300 K for La0.7Ca0.3MnO3 , synthesized by the conventional ceramic and the low temperature combustion methods and annealed at different temperatures. Temperature dependence of the dc magnetization and the ac susceptibility i…
From surface tensions of liquids and Lifshitz-van der Waals (LW) and Lewis acid-base (AB) surface tension components and the AB electron-acceptor γ+ and electron-donor γ˙ parameters determined by contact angle (θ) measurements (using the Young-Dupré equation for polar systems), the interfacial work of salvation (Wst)…
Tranilast, N-(3,4-dimethoxycinnamoyl) anthranilic acid, a widely used antiallergy drug in Japan, has been shown to inhibit transforming growth factor-beta1 release from fibroblasts and reduce collagen synthesis in keloid cells. In the present study, we have investigated the effect of this drug on cardiac hypertrophy i…
Pendimethalin, N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine, is a potent herbicide that exists in two differently coloured polymorphic crystal habits. Triclinic pendimethalin I (P) is the orange-coloured thermodynamically stable form, whereas monoclinic pendimethalin II (P21/c) is a bright-yellow metastable f…
This work reports on mesomorphic thermochromism caused by metal centres leading to visualization of van der Waals interactions. We succeeded in obtaining columnar liquid crystals exhibiting very interesting thermochromism by introduction of long chains into disk-like bis(glyoximato) d8 metal(ii) complexes. These long-…
The synthesis and first hyperpolarizabilities of a series of isoquinolines and isoquinolinium salts, and also thienopyridines, thienylpyridines, and the corresponding pyridinium salts, determined by hyper-Rayleigh scattering in solution at 1064 and 1300 nm, are reported. These chromophores exhibit markedly high β valu…
The gene encoding an extremely stable inorganic pyrophosphatase from Sulfolobus sp. strain 7, a thermoacidophilic archaeon, was cloned and sequenced. An open reading frame consisted of 516 base pairs coding for a protein of 172-amino acid residues. The deduced sequence was supported by partial amino acid sequence anal…
Facile syntheses of the meso-tetra-p-tolylporphyrin (TTP) complexes trans-(TTP)Ti(THF)(2) (1), (TTP)Sn (2), and trans-(TTP)V(THF)(2) (3) are achieved through homogeneous reduction of high-valent precursors using NaBEt(3)H. The composition of the new compound trans-(TTP)Ti(THF)(2) was determined by spectroscopic and ch…
