ABSTRACT

In the present study, Polysulfone/ABS-10% composite and Polysulfone/ABS-10%-silica nanocomposite membranes prepared for CO2 separation from CH4. A dense blend polymeric membrane with two partially miscible polymers was made and nano-silica was added into it to improve gas transport properties. The membranes were prepared by solution casting method and characterized by Fourier transform infrared spectroscopy (FTIR), and Scanning electron microscopy (SEM). Transport characteristics of single gas for CO2 and CH4 were investigated by the single gas test. Feed pressure altered from 2 to 6 bars and temperature kept at 25 ?. The gas permeability of methane and carbon dioxide were evaluated as a function of silica concentration. Permeability results show that by adding silica nanoparticles into the PSF/ABS matrix, permeability of both CO2 and CH4 increased and loading up to 3 wt.% increased the selectivity of  CO2/CH4 from 9.13 to 24.48 Barrer at 2 bars.

ABSTRACT

The ambipolar diffusion length (Ld) is an estimation of the diffusion length of less mobile charge carriers (presumably holes) which determines the performance of solar cells. The Steady State Photo-carrier Grating (SSPG) technique measures ambipolar diffusion length in mobility photoconductive semiconductor films. This technique also provide access to the minority carrier transport properties as diffusion length is proportional to the product of mobility (μ) and lifetime (τ) of charge carriers. SSPG measures the interference pattern created by the superposition of two coherent laser beams (L1 and L2). A brief description of this method was presented. Furthermore, efforts were made to understand the larger attenuated intensity of the laser beam (L2) for the interference fringes can lead to large errors in the measured diffusion length. Moreover, estimation of minority carrier transport in hydrogenated amorphous silicon (a-Si:H) and micro/nano-crystalline thin film (nc-Si:H/μc-Si:H), deposited by PECVD process was carried out. The ambipolar diffusion length in a-Si:H films found to vary from 0.23 ─ 0.11 μm for different photo-gain ( 6 x 104 to 8 x 102) and in nc-Si:H/μc-Si:H vary from 0.190 ─ 0.080 μm for different crystalline fraction (43 % - 22 %).  From these results, Ld were observed to be maximum for the film having high photo-gain in a-Si:H and high crystalline fraction in nc-Si:H/μc-Si:H.

ABSTRACT

The aim of this study is to demonstrate the utilization of sodium bentonite as a pozzolanic additive to reduce the permeability rate of stabilized clay. Sodium bentonite is identified as a natural pozzolan that can utilize to reduce the coefficient of permeability of cemented soil due to its fineness and high content of silica and alumina. Sodium bentonite wherein mixes with cement paste in an appropriate dosage, it is capable to impart pozzolanic effect; hence, reduce the coefficient of permeability of cemented soil. Other than sodium bentonite, ordinary Portland cement and silica sand were also used as the binder and particle size modifier respectively. For this purpose, soil specimens of both plain and treated clay were explored in laboratory. It was revealed that addition of 15% sodium bentonite reduced 2.11 times of coefficient of permeability.

ABSTRACT

Air-blast atomizers provide excellent atomization over a large range of fuel flow rates and very good penetration. In this study we consider an annular liquid sheet emanating from an air-blast atomizer subjected to inner and outer swirling air streams. A temporal stability analysis is carried out to model the atomization of a swirling viscous annular liquid sheet subject to axi-symmetric disturbances and inviscid swirling air streams. Numerical solutions to the dispersion equation under a wide range of flow conditions are carried out to investigate the effects of the liquid-gas swirling orientation on the maximum growth rate and its corresponding unstable wave number.

ABSTRACT

This study examined and compared the wear behavior of two different thermal spray-coating techniques. Plasma and high velocity oxygen fuel (HVOF) spraying are the most common types of thermal spray coating techniques that can be used to deposition different types of ceramic composites. Cr3C2-25%NiCr is well-known ceramic composite that can be used for extending the lifespan of products. The tribological and mechanical properties of them were investigated by tribometer (pin-on-disc) machine by applying different loads. The results show when the coated samples pushed against WC-6%Cr abrasive paper with maximum load, the rate of wear in the HVOF-coated sample is less than plasma-coated samples. However the average of wears and rate of weight loss in both of coated sample is not high. For this reason there is no big different between surface of samples before and after wear testing. Field emission scanning electron microscopy (FESEM) showed the distinctive microstructure of the HVOF and plasma coated samples before and after wear testing.

ABSTRACT

The aluminum copper alloys typically contain between 9 to 12% copper, with smaller additions of other elements. The copper provides substantial increases in strength and facilitates precipitation hardening. The copper in aluminum can reduce ductility and c orrosion resistance. The susceptibility to solidification cracking of aluminum copper alloys is increased; consequently, some of these alloys can be the most challenging aluminum alloys to weld. These alloys include some of the highest strength heat treata ble aluminum alloys. The main uses for aluminium alloy are in inte rn al combustion engines . In this work we are interesting to investigate the mechanical properties of aluminium alloy to vary the percentage of copper. The results showed that with the increa sing of copper content the solidification time increased, and increase of both the ultimate tensile strength and the hardness is obtained by the increase of the copper content.
