DOI: 10.17014/ijog.8.1.73-99 Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and electron microprobe analysis (EMPA) techniques were used to determine the mineralogy chemistry of dominant sulphide associated gold deposits at Fairview Gold Mine Barberton Greenstone Belt (BGB). The rocks ore mineral associations indicate mesothermal (orogenic) conditions for deposit. whole...

Gold is the preferred material for conductive structures in neural implants. The hitherto employed process applies adhesive layers to avoid delamination of gold from a polymeric substrate. possibility deposit without use offered by high-power impulse magnetron sputtering (HIPIMS) process. In this work, it shown that possible utilize HIPIMS onto polyimide while having enough adhesion between the...

An experimental study of the adsorption sites of metal adatoms on an oxide surface is presented. The adsorption sites of gold on the ultrathin aluminum oxide grown on NiAl 110 are determined. For the study low-temperature frequency modulation dynamic force microscopy is employed to identify the adsorption sites in real space. Results show that wave trough-like depressions in the alumina surface...

Stable suspensions of gold nanoparticles in water were prepared with high yield by a novel one-step ultrasound assisted electrochemical process. Various strategies based on the addition of either tailor-made polymers or mixtures of commercially available polymers, in the electrochemical bath have been found successful to avoid nanoparticles aggregation commonly observed by sonoelectrochemistry....

The Ulu Sokor gold deposit is classified as orogenic type with evidence from previous studies on the structural, mineralogical, alteration, fluid inclusion, and stable isotope data. This study focuses mineralogy geochemical analysis of representative ore rock samples southern part deposits. project area situated at North Kelantan state which lies Central Belt Peninsular Malaysia. main objective...

The selection and assembly of materials are central issues in the development of smaller, more flexible batteries. Cobalt oxide has shown excellent electrochemical cycling properties and is thus under consideration as an electrode for advanced lithium batteries. We used viruses to synthesize and assemble nanowires of cobalt oxide at room temperature. By incorporating gold-binding peptides into ...
