The more and more frequent use of recycled materials within the road and railway infrastructures is now an irreversible trend. In this area the use of Dry Asphalt Rubber Concrete (DARC) in sub-ballast layer seems to be a suitable technique to reach high mechanical and environmental performance even if such material sh…

Within the model of an ideal rigid-plastic body the limit behavior of the hybrid composite circular plates is considered. The exact solution of the problem of bending is built for three-layer reinforced circular plates having different angular structure reinforcement at the top and bottom layer. The material of the mi…
In this study, semiconducting thin films of undoped and In doped CdSe have been deposited by conventional thermal evaporation technique on cold glass substrates. The structural and electrical properties of the films have been investigated by means of XRD, SEM, temperature dependent electrical conductivity and Hall Eff…
A copper-poly(propyleneimine) (CuPPI) metallodendrimer was physically adsorbed onto the surface of a gold electrode to form an Au|CuPPI electrode system, which was electrochemically characterized by cyclic and square wave voltammetric techniques. The CuPPI metallodendrimer was found to be electroactive on Au electrode…

Thermo-gravimetric analysis (TGA) is a useful technique to study the kinetics of gas-solid reactions and specifically it has been widely used to investigate the carbonation reaction between carbon dioxide and calcium oxide based solid sorbents, which is the basis of a promising CCS technology. Typical conversion rates…
摘要： 微发泡注塑成型制品表面的螺旋纹及银纹缺陷阻碍了此新工艺的推广应用，此缺陷主要是由填充过程中熔体流动前沿的泡孔发生破裂造成的。为提高微发泡注塑件的表面质量，提出一种利用高压氮气进行加压并使用高压容器进行稳压的模具型腔气体压力控制方法，构建相应的模具型腔气体压力控制装置和控制系统，进行某种医疗器械外观产品的气体反压(Gas counter pressure，GCP)微发泡注塑试验，研究填充过程中模具型腔气体压力对微发泡注塑件表面质量的影响规律。结果表明，随着模具型腔气体压力的提高，微发泡注塑件表面螺旋纹及银纹逐渐减少直至消除，塑件表面光泽度显著提高，塑件表面粗糙度明显降低。对选用的ABS材料，模具型腔气体压力为3 MPa时可获…
Catalysis is a fundamentally sustainable process which can be used to produce a wide range of chemicals and their intermediates. Focussing on those catalytic processes which offer the most sustainability, this two-part book explores recent developments in this field, as well as examining future challenges. Focussing o…
Experimental results for an active magnetic regenerator (AMR) are presented. The focus is on whether or not it pays off to partly substitute soft magnetic material with non-magnetic insulation in a flux-conducting core in the magnet system. Such a substitution reduces losses due to heat conduction and eddy currents, b…
Zn/Fe-CO3 layered double hydroxide was synthesis by co-precipitation method for the adsorption of lead ions in aqueous solution. The synthesized layered double hydroxide (Zn/Fe-CO3) was then characterized by Powder X-ray Diffraction (PXRD), Fourier Transform Infrared (FT-IR) and SEM/EDX analysis. The experimental data…
In order to investigate the interior-induced fatigue crack propagation behavior of spring steel (SUP7), fatigue tests in axial loading were performed for 4 kinds of specimen with different hardness (tempered at 450℃ or 386℃) or residual stress (finished by grinding, electrochemical polishing or shot peening). Harder s…
Effect of the kind of nano-fillers on dynamic mechanical properties and morphology of the filler loaded crosslinked natural rubber (NR) is reviewed, where carbon black (CB), hydrophobic silica and hydrophilic silica are compared. 3D-TEM/electron tomography is utilized to measure a closest distance (dp) between centers…
Model rolling experiment has been conducted to investigate strip warpage behavior during single roll driven rolling. It became clear that direction of strip warpage changes with change in so-called rolling shape factor which is defined as ratio of contact arc length to strip thickness. In case of the shape factor bein…
The mechanism of recrystallization texture development is changed by the chemical composition of materials, cold-rolling reduction, and annealing treatment conditions. In this paper, we have discussed the development of the recrystallization texture for cold-rolled iron with 99.8% reduction. In cold-rolled iron with 9…
The effects of partitioning of Mn and Si during intercritical annealing on transformation behavior and mechanical properties of low alloyed TRIP-assisted steel sheets were investigated by using 0.17%C-1.5%Si-1.7%Mn steel. During intercritical annealing, Mn and Si were concentrated in austenite and ferrite by partition…
We proposed that the grain growth observed in electrodeposited Cu films at room temperature is caused by hydrogen-induced superabundant vacancy-hydrogen clusters. In this study, the relation between grain growth and hydrogen behavior in the electrodeposited Cu films was investigated using different types of plating ba…
Today is the golden age of fashion. Fashion garments and apparel has been used everywhere to cope with the fashion era. These fashion garment and apparels are made of the fabrics of various structures and components through various processes. Among them gabardine is one of the most remarkable type of fabric and appare…
The effects of (E)-3-(4-methoxystyryl)quinoxalin-2(1H)-one (Q1) and its synergistic effect with KI on the corrosion of carbon steel in 1.0 M HCl solution were studied using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements. The inhibition efficiency increases with the concentra…
Polyvinyl alcohol-Polypyrrole composite films were prepared by solution casting technique using chemical oxidative polymerization of pyrrole. Ferric Chloride (FeCl3) was used as an oxidizing agent. This technique produces conductive, flexible and free standing polymer composite films. The dc conductivity was obtained…
