Rubber is used in many industrial applications, specially those need high damping capability. Inpresent work, the effects of cyclic loading conditions on fatigue lifetime of the styrene butadiene(SBR) and nitrile-butadiene rubber (NBR) with 0,20,30,50 and 70 Phr of carbon black contentswere investigated. Two cyclic lo…
The production of cellular coatings made of polymeric materials by the extrusion process differs from solid coating extrusion in that the polymer produced by the process based on the application of blowing agents has a diphase structure (gas-polymer) with small and evenly distributed gas bubbles. The research describe…

The polycrystalline sample of complex tungsten-bronze compound Li2Pb2Sm2W2Ti4Ta4O30 was prepared by a high-temperature solid-state reaction technique. Room temperature X-ray diffraction (XRD) study suggests the formation of a single-phase compound. Microstructure of the pellet sample was studied by scanning electron m…

The structural characteristics of the BaTiO 3 /(Ba 0.5 ,Sr 0.5 )TiO 3 /SrTiO 3 superlattice on a (001) MgO substrate have been studied using X-ray diffraction. The modulation period and unit cell parameters of layers forming the superlattice have been measured. The sizes of coherent scattering regions and average micr…
This study examined the effect of porous dielectric silica gel the discharge ignition voltage and input power in a plasma reactor. For the experiment was used a plasma reactor with two mesh electrodes made of stainless steel with a mesh size of 0.1x0.1mm. The study analyzed and compared with parameters such as power,…
A novel guest biomimetic glutathione peroxidase (3,3'-tellurobis(propane-3,1-diyl) diadamantanecarboxylate, denoted as ADA-Te-ADA) was synthesized. ADA-Te-ADA functioned to overcome the disadvantages in the construction of building block for giant supramolecular biomimetic enzyme. To reveal the catalytic property of h…
The effects of laser irradiation on the surface, structure and optical properties of SnO thin films deposited on glass substrates using electron beam evaporation, are investigated. The thin film samples are irradiated using fundamental beam at 1064 nm from Q-switched Nd:YAG pulsed laser with different power densities.…
The close relationship between microstructure evolution of electrode materials for lithium-ion batteries during charging/discharging and the corresponding reaction mechanism has urged great efforts to acquire detailed microstructure information at atomic scale enabling improved understanding for reaction mechanism and…
Zinc oxide (ZnO) has a wide band gap, high stability and a high thermal operating range that makes it a suitable material as a semiconductor for fabricating light emitting diodes (LEDs) and laser diodes, photodiodes, power diodes and other semiconductor devices. Recently, a new crystal growth for producing ZnO crystal…
In this paper, we present an analytical solution of the interaction of the nanotube (NT) with a wedge disclination dipole in nanotube-based composites. The corresponding boundary value problem is solved exactly by using complex potential functions. The explicit expression of the force exerted on disclination dipole is…
RESUME Les materiaux et dispositifs thermoelectriques (TE) sont interessants pour les applications en conversion d’energie tels la recuperation de chaleur, la climatisation et la refrigeration. Depuis les annees 50, plusieurs efforts ont ete deployes pour ameliorer l’efficacite des materiaux TE pour la conversion d’en…
This paper proposes an improved modulated carrier control for single-phase shunt active power filter, which eliminates harmonic and reactive currents at ac sources drawn by nonlinear loads. This control method directly shapes line current to be sinusoidal and in phase with grid voltage by comparing a modulated carrier…
Outcomes following autologous fat grafting continue to be unpredictable. The lack of a standardized protocol for fat harvest, processing, and transplant produces variable graft retention rates. Plastic surgeons historically have relied on trial and error to modify their techniques.1 To optimize fat grafting protocols,…
Nanostructured alumina thin films were coated on stainless steel by Sol-Gel dip coating method. In order to prevent crack formation, Al2O3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. Effects of calcination temperature and withdrawal speed on structural properties were anal…
The effect of gravity on the electric potential generated by the combustion synthesis of zinc sulfide is analyzed using the numerical simulation. Recent experimental studies on generation of electric voltage during combustion synthesis of zinc sulfide (ZnS) have revealed high voltage signals (4 V) with duration about…
With the advancement of industry, the utilization of cushion package to apply on the products of civilian, sports, electric, precise equipment increases extensively, which are brittle and vulnerable that need to be protected. In the research, the Recycled High Strength PET fiber, Recycled Kevlar fiber and low melting…
As novel theories and uses of carbon nanotubes (CNT) advance, it becomes increasingly important to characterize the methods of production. One such method of CNT production uses a liquid phase precursor (hydrocarbon with nanoparticle catalyst mix) that is injected into a tube furnace with a flowing carrier gas. The CN…
The Hugoniot elastic limit and the spall strength of aluminum and copper samples pressed from a mixture of a metallic powder and 2–5 wt % C 60 fullerene powder are measured under a shock loading pressure up to 6 GPa and a strain rate of 10 5 s −1 by recording and analyzing full wave profiles using a VISAR laser interf…
