1/12/2017· When the alumina template is dissolved in H 2 SO 4, separated PB nanowires are obtained. A ferricyanide complex is used as the single source for formation of PB in a slightly acidic solution because the acid medium promotes the formation of Fe 3+ /Fe 2+ , which subsequently reacts with the residual ferrocyanide leading to formation of only PB in the solution [22c] .
Hong-Bing Hou Abstract: Simple methods for the chemical speciation of antimony, and organotin compounds were developed by atomic spectroscope. Antimony was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) and high-resolution inductively coupled plasma mass spectrometry (ICP-MS) with a hydride generation technique.
In October 2014, Sotheby''s Hong Kong achieved consecutive per-carat price records for Kashmir sapphires – first with the 12.00 carat Cartier sapphire ring at US$193,975 per carat, then with a 17.16 carat sapphire at US$236,404, and again in June 2015 when

Optical chemical sensors have promoted escalating interest in the determination of various pollutants in the environment, which are creating toxicity and may cause serious health problems. This review paper focuses particularly on the recent progress and developments in this field; the working principles and basic classes of optical chemical sensors have been briefly described.
1/7/2010· Their crystal structure consists of stacked layers made of two silica tetrahedrons fused to an edge-shared octahedral sheet of alumina (). The layer thickness is approximately 1 nm and the lateral dimensions may vary from 300 Å to several microns, giving …
1/10/2017· From industrial point of view several advantages associated with lipases makes them attractive and versatile alternative to chemical processes . These include wide availability, high efficiency and stability, lack of cofactor requirement, mild operating conditions, and use in organic solvents with retention of their highly chemo-, regio- and enantioselective action  .
2.1.3 Oils. Although trace metal analysis in used oil as usual dominates this section, some papers have concentrated on the analysis of single elements and have extended much more to alternative techniques to the normally dominant ICP-AES. Jose Luis Burguera et al., 82 describe the use of an on-line emulsifiion FI-ET AAS system to determine Cr in lubriing oils.

1/4/2013· Alumina (Al 2 O 3) and zirconia (ZrO 2) are non-bioactive ceramics and are covered by a non-adherent fibrous layer at the interface after implantation. In orthopedics they are mainly used as artificial femoral heads or acetabular liners due to their excellent mechanical strength and durability in conjunction with low friction and wear coefficients  .
