Research Article of International Journal of Nanoparticle Research Development and Characterization of Nanoparticle Metal Matrix Composites: (Al 2024-SiC NP) Muhammad Arshad Chaudhry1, Liaqat Ali2, Khalid Mahmood Ghauri2,Javed Iqbal2  1Ph.D Research Scholar, Department of Metallurgical and Materials Engineering, University of Engineering & Technology, Lahore, Pakistan 2Professor Dr. Department of Metallurgical and Materials Engineering,University of Engineering & Technology, Lahore, Pakistan Composite materials get an importance in value as an advance materials such as automotive, aerospace, aircraft, defense, medical, marine, sports, recreation and various engineering applications due to their high strength-to-weight ratio, good cast ability and better tribological properties. Al-base 2024 alloy reinforced with SiC micron and nano particles were developed using stir casting technique due to low cast, ease in fabrication, recyclability and isotropic characteristics. The development of Aluminum metal matrix nano composites (AMMNCs) is most considered material for high temperature applications because of their excellent mechanical properties, increase performance and weight saving for more reduction of fuel consumption. The results indicate that Al-SiC composite has improved physical and mechanical properties such as tensile strength, charpy impact strength, brinell hardness, density and porosity percentage. Samples with micron particles and nano particles were developed to compare the properties of both. Microstructures of the samples were studied by means of X-Ray Diffraction and Scanning Electron Microscopy. The elemental composition was also analyzed through Energy Dispersive Spectroscopy. It was found that composites of Al-SiC have better and improved physical properties in nano dimensions.

Synthesis of Biocompatible carboxylic acid functionalized Graphene Oxide as a stimulator of bacterial growth

Research Article of International Journal of Nanoparticle Research Synthesis of Biocompatible carboxylic acid functionalized Graphene Oxide as a stimulator of bacterial growth Neelima Sharma 1*, Rishi Sharma2 1Department of Pharmaceutical Sciences and Technology, Birla Institute of Technology, Mesra, Ranchi -835215, Jharkhand, India. 2Department of Physics, Birla Institute of Technology, Mesra, Ranchi -835215, Jharkhand,India. Researchers have shown great interest towards Graphene and its potential applications in various fields such as electronics, energy, materials and biomedical areas. The effects of Graphene, graphene oxide (GO) and its derivatives on bacteria activities is still controversial. Thus, how graphene and its derivatives interact with microorganisms and the mechanisms of their interactions are important issues for nanotechnology which need proper exploration. In the present investigation, graphene oxide (GO) has been synthesized and functionalized by the chemical method. The GO and COOH-functionalized GO have been characterized by Fourier transforms infrared spectroscopy; Raman spectroscopy and SEM analysis. Further, haemocompatibility study has been performed to check the biocompatibility of functionalized graphene oxide. The effect of GO and COOH-GO on the bacterial growth has been observed. The FTIR, Raman and SEM data confirm the successfully functionalization of GO with carboxyl (-COOH) group. The haemolysis test shows that GO and GO-COOH are highly hemocompatible. Interestingly, functionalized graphene oxide, can significantly stimulate bacterial growth for gram positive and gram negative bacteria, whereas as-made GO shows no effect. It can be concluded that carboxylic acid functionalized GO may act as a new, positive regulator for the growth of bacterial cells.

Background The powders of Ni-Cr Nano ferrites were synthesized with the chemical formula, NiCrXFe2−XO4 (Where X = 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0) by using citrate-gel auto combustion technique. The structural characterization was investigated by X-Ray Diffractomerter (XRD). X-ray analysis shows that the samples are cubic spinel structure (single phase) without any impurity peak and average crystallite size was in the range of 8.5-10.5nm. The dielectric measurements were carried out as a function of frequency and composition (X) at room temperature in the range of 20Hz-2MHz. The real part of dielectric constant (ε') and dielectric loss factor (tan δ) showed a decreasing trend with increasing field frequency. The ac conductivity (σac) is calculated from the dielectric measurements and it is increased with the increase of frequency. The composition dependent dielectric parameters are reported. Keywords:  Ni-Cr nano-ferrites: Citrate-gel technique: XRD: Dielectric parameters: ...

The synthesized nano particles are sintered at different temperatures like 300OC, 400OC, 500OC, & 600OC for 4 hours in air medium. The single phase cubic structure is confirmed by X-ray diffraction, the average crystallite sizes of these samples are found to be in the order of 34 nm to 60 nm. The surface morphology of the samples is studied by using Scanning Electron Microscopy. The EDS spectrum confirms the presence of Bismuth, Zinc and Oxygen without any precipitating cations.
