Chiral C(2)-symmetric electroactive bis(oxazolines) containing an EDT-TTF (ethylenedithio-tetrathiafulvalene) backbone, as promising multifunctional ligands and precursors for chiral molecular materials, were synthesized and structurally characterized, together with octahedral molybdenum and tungsten carbonyl complexe…
The quinone-methide elimination is a common, efficient methodology used in linkers designed to undergo self-fragmentation. Here, for the first time, we demonstrate this elimination in a pyridine ring system. Under physiological conditions, a compound constructed of a pyridine core, a reporter, and an enzymatic trigger…
An L-glutamide-functionalized tetraphenylporphyrin () has been newly synthesized and its self-assembling behavior in organic solvents is reported. forms nanofibrous assemblies in a dilute solution to show specific induced circular dichroism at the absorption band around the porphyrin moiety. It enables us to observe t…
The present work extends previous efforts using “micro-mixing” fuel injectors operating on hydrogen fuel to elevated pressure and temperature and includes initial evaluation of a second injector concept. A micro-mixing fuel injector consists of multiple, small and closely spaced mixing cups, within which fuel and air…
The oxidation behavior and electrical property of a Ni–Mo–Cr alloy at in a simulated solid oxide fuel cell (SOFC) anode environment (humidified and diluted ) have been studied. The thermally grown oxide scale presents a multilayered structure, which is similar to that formed in air, with densely grown in between an un…
The solidification microstructure, the thermal property, and the hardness were investigated on AZ91D magnesium alloy and on AZ91D magnesium alloy with 20 mass% gadolinium addition. AZ91D and AZ91D + 20 mass% Gd were solidified by the furnace cooling technique starting from 700°C in an Ar flow atmosphere. The microstru…
Gd 2 MoO 6 : Eu 3 + nanofibers and nanobelts have been prepared by a combination method of the sol–gel process and electrospinning. X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), high resolution transmission electron…
Proteins in thermal equilibrium are associated with conformational distributions rather than single, static structures. Although there are no experimental methods to measure the full protein conformational distribution, several methods exist to probe important aspects. Diffuse X-ray scattering is one such method. We h…
A novel shortfiber composite in which the microscopic advanced fiber reinforcements are coated with radially aligned carbon nanotubes (CNTs) is analyzed in this study. A shear-lag model is developed to analyze the load transferred to such coated fibers from the aligned-CNT reinforced matrix in a hybrid composite appli…
Part 1 Introduction: Recent advances in polymer processing: the state of the art, new challenges and opportunities Non-Newtonian fluid mechanics and polymer rheology Polymeric materials: elastomers, plastics, fibers, composites, nanocomposites and blends Compounding and mixing of polymers Screw extrusion in polymer pr…
Metal cation (metal = Cu, In and La) ion exchanged ZSM-5 zeolites as catalysts for the NO selective reduction by propane and propene in excess oxygen. The surface reactions of HC-SCR over catalysts were investigated through in situ DRIFTS method. For C3H8-SCR, adsorbed nitrate species (–NO3) were observed as main reac…
The pressure induced phase transitions of TiO 2 from anatase to columbite structure and from rutile to columbite structure and the temperature induced phase transition from anatase to rutile structure and from columbite to rutile structure are investigated by ab initio plane-wave pseudopotential density functional the…
The comfort of textile materials has been the focus of many investigations since the concern for personal well-being and improving the quality of life started to become an important issue. The aim of this paper is to simulate water vapour transfer through knitted fabrics under different environmental conditions. In th…
Informations of phosphorus fractions are important for evaluation of their status in soil and understanding of soil chemistry that influence soil fertility. To obtain such information, amount and distribution of P in different fractions of 20 soil samples of Qazvin province, Iran were determined by sequential extracti…
A new organogelating moiety, 1, is proposed as a suitable and versatile building block for the production of other gelling compounds. Linking 1 with several different molecular fragments afforded new gels with different properties. A detailed investigation of the ferrocene substituted gelator is reported in this study.
To develop a forging process for high strength Mg-Zn-Y alloys with a long period stacking ordered (LPSO) structure, the forgeability and flow stress of Mg97Zn1Y2 (at%) alloys were investigated with the upsettability test at an initial strain rate of 0.55 s−1. As-cast and extruded Mg97Zn1Y2 alloys can be successfully f…
An original design of a fluorescent dithienylethene (DTE)-based bipyridine, where donor (D) and acceptor (A) groups are located on the same thiophene ring of the DTE unit, is reported; in non-polar solvents, UV or visible excitation triggers a photochromic reaction, disrupting the conjugation and quenching the fluores…
Uniform octahedral LuVO4 microcrystals have been successfully prepared through a designed two-step hydrothermal method. One-dimensional lutetium precursor was first prepared through a simple hydrothermal route. Subsequently, a well-shaped octahedral LuVO4 sample was synthesized at the expense of the wirelike precursor…
A highly sensitive and robust method for the determination of six gadolinium species by reversed-phase liquid chromatography coupled with inductively coupled plasma optical emission spectrometry (HPLC-ICP-OES) has been developed. The gadolinium(III) complexes, Gd–DTPA2−, Gd–DOTA1−, Gd–HP–DO3A, Gd–DTPA–BMA and Gd–DTPA–…
