Ternary clusters Cu(9)In(10)S(9)(SEt)(21)(PPh(3))(3) and Cu(11)In(6)S(7)(S(t)Bu)(15) were isolated from the UV-photolysis products of precursors (PPh(3))(2)CuIn(SEt)(4) and (PPh(3))(2)CuIn(S(t)Bu)(4), respectively, and structurally characterized.
Due to the high potential of photoconductive behavior used in electrochromic and sensor devices, tungsten oxide (WO3) is the most promising candidate applied for electrochromic materials, gas sensors, and dye sensitized solar cells. Adsorbing the visible blue light by tungsten oxide nanoparticles would thus be used ef…
A Master Sintering Curve (MSC) for rutile TiO2 was constructed for Pressure-less sintering using constant heating rate dilatometry data based on the combined-stage sintering model. Construction of the master sintering curve is described and the validation is proved with rutile TiO2 under different thermal histories. T…
We present results of a parametric study on shearband formation in geomaterials, examining the influence of material dilatancy on shearband properties. The study is based on a new higher order continuum theory, called gradient elastoplasticity, developed to model localization of deformation. We present results for two…
In recent years, natural fibre composites have received considerable attention as a serious contender to replace glass fibres in composite material applications. One of the key aspects in composite materials is the interface between the reinforcing fibres and the matrix and a critical assessment of the interfacial bon…
The study addresses the spectral and photochemical properties of N-(3-ammoniopropyl)-4-styrylpyridinium diperchlorate and its substituted analogs containing either electron-donating (OMe, SMe, NMe2) or electron-withdrawing (NO2, Cl) groups on the benzene ring. These styryl dyes in MeCN form pseudodimeric complexes wit…
本研究では，実験および数値解析によりすすの一次粒子成長および凝集体形成機構を検討した．実験ではアルミナ製反応炉を用いたベンゼン熱分解実験によりすすを生成した．数値解析ではDiscrete-Sectional法を用いた粒子生成・成長モデルと，凝集体形成モデルであるCluster-Cluster Aggregationモデルをカップリングした新たなモデルを構築した．本モデルはベンゼン熱分解，核粒子生成，球状粒子の生成・成長，粒子凝集過程および焼結による凝集体中の一次粒子同士の融合・成長を考慮している．数値解析結果は凝集体一次粒子径分布および凝集体形状に関して実験結果の傾向を良好に再現することが明らかとなった．また，一次粒子の焼結による…
A new route to the octacyanoporphyrazine framework based on the interaction of metal sandwich pi-complexes with TCNE has been developed.
Europium complexes of a series of terpyridine-N-oxide ligands have been prepared and structurally characterised by crystallographic studies. While the addition of three equivalents of terpyridine-1-oxide or terpyridine-1,1'-bisoxide results in complexes with nine co-ordinate tricapped trigonal prismatic or monocapped…
Mg complex of phthalocyanine fused with bicyclo[2.2.2]octadiene (BCOD) units is prepared by the reaction of BCOD-fused phthalonitrile with Mg(OPr) 2 in PrOH at 100 ºC overnight in 42% yield.Subsequent heating the product at 250 ºC results in clean formation naphthalocyanine via the retro Diels-Alder reaction.An attemp…
The low cycle fatigue tests of the type 316LN stainless steel were conducted to investigate the cracking mechanisms in high-temperature water. The fatigue lives of the specimens tested in 310°C deoxygenated water were considerably shorter than those tested in air. For the specimens tested in 310°C deoxygenated water,…
Formally uncharged two-coordinate tellurium atoms in trialkyl(telluroseleno)phosphonium salts [(tBu2iPrPSeTe-p-Tol)+ (p-TolTeI2)-] () and {[(iPr3PSeTeI)+]2 (TeI6)2-} () behave as soft acceptors towards iodotellurate anions, thus exhibiting a novel type of Te...Te anion-->cation donor-acceptor interaction () and a chel…
In the synthesis of gallium phosphate, GaPO4, crystals via a hydrothermal route, using amphiphilic triblock copolymer F127, [(EO)106(PO)70(EO)106]–OH, as a surfactant-template, a pH-dependent morphology evolution is observed in the progress of crystal growth. By altering the initial pH level from 7.34 to 11.54, the mo…
N-trimellitylimido-L-methionine (3) as optically active diacid monomer was prepared by the reaction of trimellitic anhydride (1) with L-methionine (2) in acetic acid solution at refluxing temperature. The direct polycondensation of this amide-imide diacid monomer 3 with several aromatic diamines was carried out with t…
Metallic foams have been of considerable interest both from the industrial applicability and scientific viewpoint. In the last three decades, since the inception of the metal foam, several processes have been developed to introduce large size pores, almost uniformly distributed, in the metallic materials. These proces…
[...] Książka składa się z 8 rozdziałów, z których każdy można rozbudować do obszernej monografii. W pierwszych trzech rozdziałach omówiono podstawowe prawa rządzące złożonymi procesami fizycznymi i chemicznymi decydującymi o dynamice palności polimerów. Dotyczą one zjawisk zapłonu i rozprzestrzeniania się płomieni pr…
This work investigates the correlation of topography, morphology, and optical properties between a rough substrate and the coatings covering it. A model substrate (YUPO((R)) film, "synthetic paper") was coated with increasing amounts of rod-like precipitated calcium carbonate (PCC) pigment. A versatile roughness analy…
The main effort in the area of crystallization for structural genomics is currently being invested in automation of high-throughput screening procedures to identify potential crystallization conditions. However, screening in itself, even in massive quantities, is not enough; it has to be complemented by an equally imp…
This investigation focuses on the synthesis and characterization of an intumescent flame-retardant (IFR) agent. Three steps are used in the synthesis process. Meanwhile, the structure is characterized by Fourier transform infrared spectroscopy (FTIR), magic-angle spinning nuclear magnetic resonance (MAS-NMR) 13 C spec…
Current methods for new materials development focus on either deeper fundamental-level studies or generation of large quantities of data. The data challenge in materials science is not only the volume of data being generated by many independent investigators, but its heterogeneity and also its complexity that must be…
