Efforts have been made to investigate a treatment process that produces minimum effluents (i.e., environmentally friendly), and yet significantly increases the quality and heat resistance of a fibrous collagen material for the leather industry. The structural properties of collagen fibrils in chrome tanned bovine leat…
Aggregate formation in axenic and microbial co-inoculated batch cultures of Aulacoseira granulata (Bacillariophyceae). Aggregate formation involving diatoms is a well-known process, especially in the marine environment. The aim of this paper was to observe natural aggregates formation in axenic and microbial co-inocul…
Glycolysis of poly(ethylene terephthalate), PET, waste using trimethylol propane (TMP) or pentaerytheritol (PEr) was used to produce suitable hydroxyoligomers for polyurethane foams. The glycolysis was carried out in the presence of manganese acetate as a catalyst, under high and normal pressure atmosphere in xylene a…
As principal product to prevent pollution flashover for overhead transmission lines,composite insulators are applied to power networks in large quantity,but existing detection methods cannot effectively detect the inner-defect of composite insulators,so that the inner-defect becomes hidden danger to secure operation o…
Dynamic Behavior of reactive powder concrete(RPC) is studied by using a split Hopkinson pressure bar.At static state and dynamic state with different impact velocities,a series of compress tests of plain RPC,RPC containing polypropylenefiber and RPC containing steel fiber were carried out.The influence of transverse c…
The International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) was founded with the aim to promote scientific cooperation in the area of construction materials and structures worldwide. This mission is achieved through collaboration of leading experts in construction prac…
The deformation behavior of a magnesium alloy tube during press bending is investigated to clarify the effect of the difference between tensile and compressive stress-strain curves of magnesium alloy experimentally and theoretically. The bending experiments using a mandrel of wires are carried out at room temperature.…
To account for the physical mechanisms of failure, the concept of thermal activation of damage and failure has been adopted as basis for this material model development. This basic assumption makes the proposed approach compatible with the Mechanical Threshold Stress (MTS) model, which was used as the strength part of…
Using reactive radio-frequency magnetron sputtering, ZnO films with strong c-axi s orientation have been deposited on Si (100) substrates at temperatures ranging from room temperature (RT) to 750℃. We have studied the influence of growth te mperature on the structural characteristics of the as-deposited films in morph…
his work reports the effects of solvent properties, solvent system, electrostatic field strength, and inorganic salt addition on electro-spinnability of the as-prepared polystyrene (PS) solutions and morphological appearance and/or size of the resulting fibres. The single solvents were 1,2-dichloroethane (DCE), dimeth…
AbstrAct Purpose: The main aim of presented work was to find a sintering conditions (temperature and time) for manufacturing of a Ni(1-X)Ti50CuX alloy (where X = 2; 3; 5; 10; 15; 20 and 25at%.) by powder technology. Design/methodology/approach: Various conditions of sintering considering temperature and time were appl…
phosphor was produced by a coprecipitation method. The morphology of the particles could be controlled by adjustment of the pH value and the heat-treatment method used. The pH value of the coprecipitation solution was a critical parameter for the luminescent properties of the phosphor. The improved chromaticity in sma…
Abstract AM1 semi‐empirical method was used to optimize the barbituric acid derivatives substituted with glucosyl B 1–5 (series B ), and the thiobarbituric acid derivatives substituted with glucosyl T 1–5 (series T ). Based on the optimized structures, INDO/CI method was adopted to calculate the electronic spectra. Me…
We present the results of tests on rotor-spun blended yarns, made with a high proportion of flax, and rotor-spun all-cotton yarns. Of special concern was the method of preparing the fibres and sliver. The flax/cotton sliver was made up of medium-long cotton, and the flax fibre was shortened and reduced in diameter by…
The simulation of axisymmetric drop impact onto a solid surface is now commonplace, but precise agreement between simulation and experiment is elusive, particularly when capillary effects are important. The reason is related to the complex relationship between the contact angle and the contact line velocity. In fact,…
The redox process undergone by the electrochemically synthesized poly( -dithiodianiline), poly(DTDA), has been examined in acetonitrile-water mixtures by electrochemical and spectroscopic techniques. The spectroscopic properties of this material are equivalent to those exhibited by the chemically synthesized one. The…
The shape memory effect (SME) induced by the magnetic field is interesting and important for physics and application. The ferromagnetic Ni2MnGa films with various compositions were deposited on a poly-vinyl alcohol (PVA) substrate with a radio-frequency (RF) magnetron sputtering apparatus using four kinds of Ni–Mn–Ga…
Abstract Simple thermolysis routes to CdS, ZnS, and CoP nanorods have been developed in our laboratory. The structural properties of the nanorods obtained were elucidated by means of X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HR-TEM). Arguments and calculations in support of the cont…
This work is a brief review of physicochemical properties of modern cathode materials for Li-ion bat-teries. These intercalated transition metal compounds of layered, spinel or olivine-type structure exhibit a correlation between their microscopic electronic properties and the efficiency and mechanism of lithium inter…
The effect of composition and hot rolling conditions on the shape memory effect (SME) in the Fe–Mn–Si-based system has been studied to obtain improved shape memory without the need to rely on “training”. It has been found that the texture is not markedly affected by rolling conditions, and texture is therefore not a m…
