Nanoparticles of Kaempferol were prepared using varying polymer drug ratio with PLGA (50:50) as the polymer, using solvent displacement method. The prepared nanoparticles were screened for the various studies like size and shape determination using light scattering and SEM. The in-vitro antioxidant profiles of the pre…
Green manufacturing is a sustainable approach, designed to use energy, water and other resources more efficiently thereby reducing the overall impact on the environment. Improved quality of life, better health conditions and diminished costs are other benefits. This paper focuses mainly on the foundry industry, as bei…
Abstract Sulfosuccinate esters are vastly used in different formulations as wetting agents and dispersants. Hemi-ester, diester, ethoxylated, and ethoxylated ester derivatives of maleic anhydride, maleic acid, and fumaric acid are converted to the saturated or corresponding sulfosuccinates by the reaction of the doubl…
In this paper we propose a symmetric q -deformed Tamm–Dancoff (S-TD) oscillator algebra and study its representation, coordinate realization, and main properties. In particular, the non-Fibonacci (more exactly, quasi-Fibonacci) nature of the S-TD oscillator is established, the possibility of relating it to a certain -…
This research work mainly deals with the mechanical and microstructure properties of various thermal barrier coating (TBC) materials for an internal combustion engine piston using plasma spraying technique. Three thermal barrier coating Materials namely the combination of Aluminium Oxide with Titanium oxide (87%Al2O3…
The APR1400 is equipped with four safety injection pumps driven by two emergency diesel generators. However, the design has been changed so that the four safety injection pumps are driven by 4 emergency diesel generators during the design certification process from the U.S. NRC. Thus, 4 safety injection pumps (SIPs) a…
Corundum structured Mg4Nb2O9 dielectric ceramics with the excess of MgO were prepared by the sol–gel process and microwave dielectric properties were investigated with the excess of MgO. First, according to the stoichiometric ratio of Mg4Nb2O9 phase formation was studied by means of XRD analysis by adjusting the ratio…
Research studies on the epoxidation of allyl alcohol, methallyl alcohol, crotyl alcohol and 1-butene-3-ol over the titanosilicate catalysts—Ti-SBA-15 have been conducted. The studies were carried out in an acetonitrile medium and in water. However, water was introduced only with an oxidizing agent, which was a 30 wt%…
Field electron emission (FE) from a structure‐defined single‐walled carbon nanotube (SWNT) was observed experimentally. A series of observations of the same SWNT by scanning electron microscopy, field emission microscopy, and transmission electron microscopy were performed for the characterization of the SWNT emitter.…
An investigation was carried out to understand the effect of process variables on the microstructure, hardness and wear properties of surface modified Cu-10Sn bronze alloy. The surface modification was carried out using Gas Tungsten Arc (GTA) as the heat source. Hardness and wear rate of the modified layer were measur…
In the present investigation, effect of minor additions of magnesium (Mg) content on the dry sliding wear behavior of A356 alloy has been reported. Alloy composition, normal pressures and sliding distances on A356 alloy has been studied. The worn surfaces were characterized by SEM microanalysis. The results indicate t…
The expectations over novel composite materials have been increased especially in automotive and aerospace applications due to its superior weight to strength ratio and tailored mechanical properties. In this frame work, aluminum alloy AA5083 alloy matrix reinforced with micron (10% wt – 5% wt) and nanoparticles (1% w…
The properties of metals and alloys can be changed by heating followed by cooling under definite conditions to make them suitable for specific applications. Carburization is a method of producing mild steel having tough inner core and hard outer surface. Three Heat Treatment process namely Quenching, Carburizing and T…
The structures of the Fe(2 and 4 ML)/Cu(001) films before and after CO adsorption are revealed by EXAFS. The Fe(2 ML)/Cu(001) film shows an fcc structure before and after CO adsorption. The bare Fe(4 ML)/Cu(001) film also have an fcc structure. However, the CO adsorbed Fe(4 ML)/Cu(001) film changes its structure to th…
This paper deals with the preparation of coconut shell powder reinforced polymer matrix composite. The composite is prepared with 20% volume fraction of coconut shell powder and the effect of stirring parameters on the tensile strength of composite is studied.
PURPOSE: To assess the feasibility of using a hybrid Maximum-Entropy/Nonlinear Least Squares (MEM/NLS) method for analyzing the kinetics of hyperpolarized dynamic data with minimum a priori knowledge. THEORY AND METHODS: A continuous distribution of rates obtained through the Laplace inversion of the data is used as a…
This paper reports the influence of the etching time on structural characteristics of porous silicon manufactured by electrochemical etching (ECE) anodization p-type silicon wafers. Micro and nano-structural features of the samples are mainly investigated by XRD and AFM techniques. The morphological properties of PS l…
We report on the effect of CdCl 2 treatment on CdTe microwires that were grown using a simple close-spaced sublimation method.Au particles were used for catalytic vapor-liquid-solid growth of the CdTe microwires with a direct band-gap of ∼1.49 eV.The optical, morphological and structural properties of the CdTe microwi…
Sulfonated polysulfone membrane is one of the alternative membranes as replacing Nafion membrane for the fuel cell application. This membrane was prepared by introducing sulfonic group in the polysulfone structure backbone, so that provides the ionic membrane. However, more ionic groups in the SPSF membrane lead to lo…
