In textile sector the use of natural sources is advancing day by day for function based articles. In this project antimicrobial sewing thread is prepared by using natural sources. Chitosan and silver nanoparticles are used in different concentrations for this purpose 100% cotton yarn is used for this project. Chitosan…
The role of boron and alumina particulate on the microstructural stability of as-atomized FeAl40at% base alloys in the temperature range of 600-1200°C was evaluated. The alumina particulate reinforcement combined with the boron microalloying prevents the abnormal grain growth and enhances the microstructural stability…
PURPOSE: To evaluate the healing of skin wounds induced experimentally in rats using a crystalline cellulose membrane (Veloderm ® ). METHODS: Thirty-two rats were divided into two groups: control group (CG) wounds treated with a solution of 0.9% sodium chloride and Veloderm ® group (VG) wounds treated with a crystalli…
Increase of the radiation-chemical resistance of glasses for radioactive waste immobilization Matrix glass composition for a possible immobilization of radioactive waste is selected. Borosilicate glass is low-alkali and relatively low-melting. It has a sufficiently high initial chemical resistance. To improve radiatio…
Aluminum doped Zinc Oxide (ZnO:Al, AZO) thin films were prepared by the Sol-gel spin coating method. The Sol solution was prepared with different Aluminum concentration corresponds to 0.002 to 0.01 mol %. The XRD pattern of the films exhibits a pref erential c-axis orientation along the (002) plane. Optical properties…
Zirconium hydroxide (Zr(OH) 4 ) was synthesized by the sol-gel method using zirconium n-butoxide and 1-butanol as synthesis precursors. A part of the synthesized material was impregnated with phosphotungstic acid (H 3 PW 12 O 40 ) in order to evaluate the effect of this dopant agent on the thermal, textural and struct…
The original function of the process of platforming is to develop heavy naphtha (HSRN), coming from the atmospheric unit of distillation with a weak octane number (NO = 44), to obtain a mixture of fuels â number octane raised by catalytically supporting specific groups of chemical reactions. The installation is divide…
This Paper is concerned with transient thermoelastic problem of a thin circular plate occupying the space h , with radiation type boundary conditions. In this paper an attempt has been made to determine the temperature distribution, displacement function and thermal stresses of a thin circular plate with the help of i…
The use of environmentally benign materials like plant leaf extracts for the synthesis of silver nanocoats offers numerous benefits of eco-friendliness and compatibility for pharmaceutical and biomedical applications as they do not use toxic chemicals in the synthesis protocols. Three main aspects were taken into cons…
Laser-assisted etching process with a step-gradient illumination intensity of 630nm laser wavelength was conducted to produce high porosity and minimum thickness of gradient – porosity porous silicon layer (GPSi). The structural properties were studied with the aid of scanning electron microscopy. The porous surface c…
Young’s modulus needed for realizing a numerical analysis model with finite elements dedicated to studying static strain on an artificial bone, made out of composite material (polyester resin reinforced with fiber glass) is determined, as well as Young’s dynamics modulus needed for analysis through numerical simulatio…
During the scaling down of the manufacturing systems, the size effects in the fabrication of metallic components become significant and play a critical role in the performance of desktop factories. In this study, the ring compression tests (RCTs) were adopted to investigate the coupling size effects in micro/meso form…
Experimental verification of various thermo-mechanical (TM] processing schedules, with aim to modify the structure characteristics using press forging of Si-Mn TRIP (Transformation Induced Plasticity) steel, was carried out. High strength and ductility of TRIP steels is attributed to the TRIP effect resulting from the…
Alloys based on FeAl intermetallic phases have a heat and corrosion resistance at high temperatures. With the addition of carbon in alloy the carbides appear which makes cast highly resistant to abrasion. However, this material is not widely used because of the presence in the microstructure of the aluminum carbide, w…
The formation of strong internal transport barrier in edge plasma of small size divertor tokamak has been performed with B2SOLPS0.5.2D fluid transport code for wide range of parameters. The conclusion has been made that, switching on / off co- and counter-NBI did not change the profiles of plasma parameters significan…
The aim of the present work is dilatometric study, within the range from room temperature to 550°C, of two aluminum based sheets containing some alloying elements in different proportions. The level of the Mn concentration in sheet 1 is higher than that in the sheet 2. But, the Fe concentration in the latter sheet is…
Scientific research takes place in silos, especially as far as hard and soft sciences are concerned. Some of these silos are large and confortable places where to conduct research. They cater to communities that present their work in specialized journals and congresses that tend to be closed on their own particular wo…
M points, which originate from the bulk-band inversion at the L points. We also found that the energy location of the Dirac point and the Dirac velocity are different from each other. This ARPES experiment demonstrates the surface states on different crystal faces of a topological material, and it elucidates how mirro…
In-situ polymerization of pyrrole was carried out with zirconium oxide, in the presence of oxidizing agent ammonium persulphate, to synthesize polypyrrole/zirconium oxide composites, by chemical oxidation method. The polypyrrole/zirconium oxide composites were synthesized with various compositions viz., 10, 20, 30, 40…
Background: Composite materials reinforced by glass fibers are widely used in various applications ranging from aerospace to sporting goods due to their remarkable properties including high strength to weight ratio and high modulus to weight ratio. However, the addition of nanoparticles as reinforcement shows promisin…
