The synthesis of hexagonal ring-shaped structures of zinc oxide using nanosphere lithography and metal/metal oxide sputtering is demonstrated. This synthesis exploits the surface re-emission of zinc oxide to deposit material in regions lying out of the line-of-sight of the sputtering source. These rings can nucleate the hydrothermal growth of zinc oxide crystals. Control over the growth could b...

the lead and zinc sample from goosh-e-fill mine with 2.4%pb, 8.0%zn and 10.0% fe, was used in different flotation experiments to recover lead and zinc minerals. the valuable minerals in prepared sample were oxidized and the results showed that the lead minerals floated at ph= 9.5 and 11.5, probably it can be due to existence of two or more types of lead minerals. the best result was achieved fo...

Although alloy tin plating has been known and used for many years, this paper will describe the use of a new non-cyanide tin/zinc alloy as a possible replacement coating for cadmium and the use of a tin/nickel alloy as a possible substitute for barrel decorative chromium plating. A review on the corrosion properties of tin, zinc and cadmium compared to tin/zinc alloys and review of the properti...

The Tyr402His polymorphism of complement factor H (FH) with 20 short complement regulator (SCR) domains is associated with age-related macular degeneration (AMD). How FH contributes to disease pathology is not clear. Both FH and high concentrations of zinc are found in drusen deposits, the key feature of AMD. Heterozygous FH is inhibited by zinc, which causes FH to aggregate. Here, zinc binding...

The Zn and Pb concentration was determined in 45 samples of bull semen from three Artificial Insemination Stations (A,B,C) differing in degree of environmental pollution. Bull semen was diluted with Biociphos-Plus to such an extent as to obtain 16 million sperm cells in an insemination dose. The research aimed at assessing the correlation between zinc, lead and other parameters influencing the ...

As an important tectonic unit of Eastern Tethyan domain, Sanjiang orogenic belt started from the expansion, subduction, subtraction and closure Paleozoic Paleo-Tethys Ocean, went through opening Neo-Tethys Ocean subduction collision process Indian continent ended in Himalayan comprehensive intracontinental convergence uplift orogeny, forming a giant composite composed several island arc belts s...

Metallic zinc is a promising negative electrode for high energy rechargeable batteries due to its abundance, low-cost and non-toxic nature. However, the formation of dendritic zinc and low Columbic efficiency in aqueous alkaline solutions during charge/discharge processes remain a great challenge. Here we demonstrate that the dendritic growth of zinc can be effectively suppressed in an ionic li...
