The effect of Si on the oxidation resistance of high purity Nb containing 19% Cr ferritic stainless steels have been investigated by means of isothermal heating at temperatures up to 1273 K in air and, the structures of scale and the scale/metal interface were investigated with FE-SEM and FE-TEM. The results are as fo…
We report on electronically excited-state dynamics of three different trifluoromethyl C60 fullerenes (TMFs, C60(CF3)n: C60/4-1, C60/6-2, and C60/10-1, featuring four, six, and ten trifluoromethyl groups, respectively) using steady-state and time-resolved optical spectroscopy as well as ultrafast pump/probe transient a…
In this work, copper sulfide (CuxS) thin films were deposited by photochemical deposition (PCD). Although deposition of CuxS thin films via PCD undergoes both heterogeneous and homogeneous reactions, we were able to determine the process conditions that will promote the heterogeneous surface reaction on the surface of…
Zinc-doped Tin-dioxide thin (SnO 2 ) films were synthesized on c-alumina substrates by radio-frequency (rf ) sputtering. To fabricate zinc-doped SnO 2 thin films with different concentrations of zinc, an insulating zinc-doped SnO 2 target was placed on a conductive non-doped target. Thin films were then deposited at d…
A vibration suppressor is used to change the natural frequency of an elevator rope, and to prevent resonance. The elevator rope is modeled using a string. Linear string vibration is well known. However, the vibration of the string that has a vibration suppressor has been studied for a few conditions because of its geo…
The substitutional solid solutions (ZnSe)x (CdS)1-x of various compositions have been obtained using the isometrical diffusion method of binary compounds (ZnSe and CdS), modernized by taking into consideration their physicochemical properties [1] . The X-ray and electron microscope researches have been carried out, an…
Magnesium based composite containing 10 vol% Al2O3 particle was produced by a mechanical milling (MM) and spark plasma sintering (SPS) process and the nanoparticle formation by Mg/Al2O3 interfacial reaction was investigated in detail. The microstructural observation of the MM powder and SPS compact was carried out by…
Within the validity of the first-order Born approximation, the near-field evanescent wave is analytically obtained from the scattering of a monochromatic plane wave from a spatially deterministic hollow particle with a semisoft boundary. The scattered spectral density shows the fluctuating profile in any cross-section…
Ultra-low cycle fatigue (ULCF) loading conditions raise a complex problem for design and safe exploitation of steel constructions in seismic active zones on our planet. The investigation of the damage and failure of steel constructions under loading with large strain amplitude can contribute to the development of safe…
The TiO 2 /amorphous carbon composite, with narrower band gap caused by oxygen vacancy, doping carbon and bridging hydroxyls, has good visible light property. In the photodegradating RhB process, hole and superoxide radical are the main active species.
Although the Bi2S3 QDs have an ideal bandgap for the efficient light absorbers, the Bi2S3 QDs sensitised solar cells generally indicate low photovoltaic properties owing to the active photocorrosion of Bi2S3 QDs. Herein, we report the enhancement of Bi2S3 QDs sensitised solar cells using the co-sensitisation of Bi2S3…

In this study, mixtures of rice husk/rice husk ashes (RHA) with RB on different ratios were prepared. Dielectric permittivity (ε'), loss factor (ε") and AC conductivity (σ') were measured in the frequency range of 4 Hz to 1 MHz in ambient temperature. Results for mixture of RHA and RB indicate that a dipolar relaxatio…
Pharmaceutical research has recently been focusing on new inject able drug delivery systems which provide long therapeutic effects, minimum initial burst effect, reduced side effects, and involving simplified production stages and facilitate application process. In situ forming micro particle (ISM) systems, one of the…
The influences of the water content on the electrochemical properties of Type 304 stainless steel were studied through cyclic voltammetry and chronoamperometry in the ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMI-TFSI). The electrochemical behavior of stainless steel was explained by…
Earth dam with impervious element in the form of asphaltic concrete core is currently the most promising type of earth dams (due to simple construction technology and universal service properties of asphaltic concrete) and is widely used in the world. However, experience in the construction and operation of high dams…
Pulverized combustion fly ash (PFA) from the Power plant Nováky (Slovakia) is analyzed for its potential use in the production of building ceramics. Three materials are used to prepare the mixtures: illite-rich clay (IRC), PFA and IRC fired at 1000 °C (called grog). The mixtures contain 60 % of IRC and 40 % of a non-p…
Fly ash is one of the major residues generated during combustion of coal in thermal power plants. Fly ash brick technology is the process of converting industrial waste materials into quality building material. Glass wastes become the greater threat to environment and also to the developing countries. GGBFS is an alte…
This paper addresses the derivation of a micromechanically motivated incremental mixed-mode traction separation law in the context of cohesive zone modeling of crack propagation in ductile metallic materials. The formulation is based on the growth of an array of pores idealized as cylinders which are considered as the…
The shaft furnace, which is a scrap melting furnace, plays an important part as an energy supplier in a steel works because the shaft furnace produces high calorie gas. The shaft furnace is required either to reduce the coke rate or to increase the exhaust gas calorie, corresponding to the energy balance in the steel…
