Laser Aided Manufacturing Process (LAMP) can be applied to repair steel die/molds which are currently repaired using traditional welding process in industry. In order to fully understand the advantages of laser deposition repair process over traditional welded-repair process, the mechanical properties such as tensile strength and hardness of H13 tool steel samples produced by these two processe...

This project studies the synthesis process of 2-D nanostructure of Bismuth oxycholride(BiOCl). The experiment involves synthesis of BiOCl particles and its exfoliation steps. BiOCl will be synthesized from Bismuth Nitrate (Bi(NO3)3) or Bismuth Cholride(BiCl3) with water, and Hydrochloric acid(HCl). Synthesized particles will be dispersed in Methyl Amine-Methanol solution and subjected to sonica...

The Cu/ZnO nanocomposite films have been synthesized by cathodic electrodeposition and characterized using X-ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), photoluminescence (PL) and field emission microscope (FEM). The XRD pattern shows a set of well defined diffraction peaks, which could be indexed to the wurtzite hexagonal phase of ZnO. ...

The livers of rats were fixed by perfusion with glutaraldehyde, treated with the revised tannin-osmium method of MURAKAMI (1974), freeze-cracked by the method of TOKUNAGA et al. (1974), critical point dried and vacuum-evaporated with a thin metal layer. The endothelial cells and Kupffer cells of liver sinusoids were examined under the scanning electron microscope (SEM). The endothelial cells li...

Nano size nickel copper ferrite powders (NiCuFe2O4) have been prepared by a prepared by Co precipitation method. The resulting powders were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM).The result showed nanosize nickel copper ferrite(35.65nm). The powders showed extensive XRD line broadening and sizes of crystals observed from the XRD line broadening was35.65 nm,...

This paper describes the fabrication and mechanical testing of Al-Mg-boron carbide particulate composites using stir casting technique. The size of the boron carbide particulates is ranging between 30 to 100 μm. The boron carbide contents are varied from 3 and 7% by weight and are dispersed in the alloy matrix. The mechanical properties of the castings, particularly their tensile properties and...

The skin armour and posterior spiracles of L1, L2 and L3 of Oestrus ovis (Diptera: Oestridae) are described and documented photographically by a scanning electron microscope. The complex and variable morphology of the attack organs of larvae of different stages makes it easier to understand better their exceeding adaptability to the host. The SEM survey has also allowed an apparently unreported...

The aim of this work is to determine the fatigue life of 316L stainless steel. The mechanisms of fatigue of 316L stainless steels were investigated and discussed. The fatigue tests were carried out at constant-amplitude cyclic loading with load ratio R=0.1. Scanning Electron Microscope (SEM) is then used to examine the fracture surface. The results show that the fatigue limit of 316L stainless ...

Nanotechnology has a great influence on modern technology, just like the development of DNA profiling on biotechnology in the past 50 years. Because of applying knowledge and techniques from natural science, forensic science aims to identify, individualize and evaluate evidence. Evidence will then be used to reconstruct crime scenes, guide investigations and bring criminals to justice. Nanotech...

Excess heat was produced at the rate of about 1.2 watts during electrolysis of heavy water with a titanium cathode weighing 0.0625 g. Analysis of the electrodes before and after electrolysis with a scanning electron microscope (SEM) and an energy dispersive spectrometer (EDS) revealed that new surface topographical features with concentrations of unexpected elements (S, K, Ca, V, Cr, Fe, Ni, an...
