Abstract Zinc oxide (ZnO) is a direct wideband gap semiconductor material with band of 3.37eV at room temperature. It can absorb ultraviolet light wavelength shorter than 385nm and blind to visible light. Using different growth methods or conditions, the final prepared ZnO nanomaterials have structures, which be presented as nano dots, nanowires, nanoribbons, rings, tubes other structures. In t...

Gene editing is one of the hottest topics in cancer research. A Chinese research team has now developed a gold-nanoparticle-based multifunctional vehicle to transport the “gene scissors” to the tumor cell genome. As the authors report in the journal Angewandte Chemie, their nonviral transport and release platform of gene-editing systems has the additional advantage of combining hyperthermal can...

Processing of gold ores with high sulfide minerals is problematic as they consume cyanide and reduce gold leaching. Optimization of gold leaching and cyanide consumption requires a methodology to estimate the amount of exposed cyanicides, their leaching kinetics, and speciation of cyanide complexes that consume the free cyanide and compete with gold. In this paper, a physico-chemical approach i...

Onzon-Kanbani area is a western flank of Mogok Metamorphic Belt where gold mineralization is hosted as auriferous quartz-vein with epithermal low-sulphidation characters. Mineralization is closely associated with NE-SW trending fracture or shear zone probably related to the dextral movement of the Sagaing Fault system. Mineralization related hydrothermal alteration is developed as narrow zones ...

Nanocomposites are combinations of nanomaterials with other molecules or nanoscaled materials, such as nanoparticles or nanotubes. In general, these novel nanocomposites have different physical and chemical properties from the constituent particles or wires, and will thus allow new kinds of applications. Among these nanocomposites, gold-carbon nanotube (AuCNT) composites are of particular inter...

An imine-based approach was developed to prepare Janus gold nanoparticles (Janus AuNPs) having amine functionality on one patch of the surface and a polyethylene glycol unit on the other. This unique technique features covalent bonding as the force to immobilize AuNPs on the template, enabling direct modification of AuNPs in both water and organic solvents. Colloidal clusters were then obtained...

The Golgi-Cox is a gold standard technique to stain the neurons. However the major limitations of the study are that it is time taking and inconsistent. In this paper we describe a modification of the Golgi–Cox method, in which the tissue blocks were immersed in rapid Golgi solution and silver nitrate for staining of neurons in rat brain. The method is simple, reproducible, rapid, inexpensive a...
