The effect of grain size on the susceptibility of high-strength low-alloy steels to hydrogen environment embrittlement in a 45 MPa gaseous hydrogen atmosphere was examined in term of the hydrogen content penetrating the specimen during the deformation. Notch tensile tests were performed in a 45 MPa hydrogen environmen…
In this study, different samples of commercially available breathable polyurethane (PU)-coated fabrics were experimentally tested applying the crumple/flex method. The flexing fatigue resistance test involves the nucleation of damage that is responsible for coated fabric failure. Therefore, views of coating were made…
Thermodynamic assessment of the Cu-Fe-Cr system was undertaken within the framework of the CALPHAD method. A set of self-consistent thermodynamic parameters was obtained taking into account new experimental data on the mixing enthalpy of liquid ternary alloys and literature information on the phase transitions. Isothe…

ゾル–ゲル法によりPdドープシリカ膜を製膜し，水素透過特性，熱安定性，水素還元による気体透過特性の変化，耐水蒸気性について検討した．Pdドープシリカ膜のTEM観察より，Pdドープシリカ層の膜厚は80 nm程度であることが明らかになり，超薄膜形成が可能であった．また，Pdはシリカマトリックス中に，数nmから10 nm程度の大きさで分散していることが明らかになった．550℃空気雰囲気で製膜したPdドープシリカ膜（Si/Pd53/1）は，乾燥窒素雰囲気（500℃）で熱安定性を有するが，還元雰囲気（500℃, H2）でPdが凝集し，シリカネットワークの緻密化と粒界細孔を閉塞した．550℃水素雰囲気で製膜したPdドープシリカ膜（Si/Pd5…
A simple, rapid, selective and quantitative HPTLC method has been developed for determination of Andrographolide in different samples of Andrographis paniculata (Whole Plant). The alcoholic extract of Andrographis paniculata (Whole Plant) samples were applied on TLC Aluminium plate pre coated with Silica gel60 GF254 a…
Hydrogen sulfide contaminates the geothermal brines that are encountered in the drilling of wells. It promotes the corrosion of the drilling equipment, pipelines, vessels, forms sulfide scales, which plug tubulars, and degrades the quality of the produced oil. This work aims to study the feasibility of electrochemical…
The use of polymeric materials is nowadays increasingly in a many important applications including packaging, building, appliance, electronics, automotive, aerospace and much more. Polymers already have a range of applications that far exceeds that of any other class of material available. Joining is a critical step i…
In order to verify the assignments of the vibration modes and to find correlations in the changes induced by Eu2O3 in strontium magnesium phosphate with the composition of 27.5SrO-27.5MgO-45P2O5 as phosphor host matrix was prepared and investigated using Raman and Infrared (IR) spectroscopy. The doping concentration o…
Abstract We have investigated the efficiency of the coupling of adsorption on a zeolite material (DAY) and UV or V-UV irradiation for the treatment of VOC containing air streams. We have compared the efficiency of photodegradation of two pollutants (1-butanol and toluene) in the absence and in the presence of TiO2 dep…
The restoring effect on worn metal surfaces from auto-reconditionging agent containing serpentine,mineral magnesium silicate hydroxide of empirical formula Mg6(Si4O10)(OH)8,as a main component has been widely interested and recognized by specialists in the fields of both science and technology in our country.As an exa…
The steady and dynamic rheological behavior of polyacrylonitrile/1-butyl-3-methylimidazolium chloride(PAN/Cl) solution system was studied using a stress rheometer.The effect of the relative molecular mass(Mη) of PAN on the steady and dynamic rheological behavior of the solution system was discussed.The results showed…
Comparative pulmonary toxicity of metal oxide nanoparticles is addressed for several different materials. The size of the particles is an important variable which depends on both the fundamental particle size and the aggregation of nanoscale particles into larger clusters. The solubility of each material in lung fluid…
Twenty-four nitropyzarole compounds and their derivatives were investigated by density functional theory.Their optimized geometries and electronic structures were calculated at the B3LYP/6-311G(d,p) level.Optimized geometries of these compounds show that they have no imaginary frequencies,and they are stable on the po…
In order to research the temperature susceptibility of SBS modified asphalt,six types of modified asphalt binders were prepared with Zhenhai neat asphalt,radial SBS4303 and SBS401,linear SBS1192 and SBS503.The penetration,viscosity,penetration index(PI) and viscosity temperature susceptibility(VTS) of all the asphalt…

Objective Using the activated carbon nanoparticles (ACNP),silicon dioxide nanoparticles (nano-SiO2) and titanium dioxide nanoparticles (nano-TiO2) to investigate the effect of nanoparticles of different chemical compositions on the mitochondrial membrane potential (MMP) and level of reactive oxygen species (ROS) in hu…
The changes in the anode and cathode potentials in the horizontal plane of a polymer electrolyte fuel cell (PEFC) under starving conditions for either air or fuel were studied using a single cell furnished with four reference electrodes which were located around the anode and the cathode. The distance between a refere…
A systematic study on the effects of solute carbon and cementite density on ductility was conducted in low-carbon Al-killed steel with 0.022 mass% C. The results obtained are as follows; 1) Total elongation was impaired by the presence of solute carbon. The deterioration is mainly caused by a decrease in local elongat…
