The preparation of gold nanoparticle (AuNP) assemblies was conducted by the synthesis and dipolar assembly of ferromagnetic core-shell nanoparticles composed of AuNP cores and cobalt NP shells. Dissolution of metallic Co phases with mineral acids afforded self-assembled AuNP chains and bracelets.

Low temperature ultramicroincineration was employed to determine the morphological localization of "structure-bound" mineral and/or metallic elements within biological cells at the electron microscope level. This technique chemically removes organic material from thin sections of tissues with reactive, excited oxygen instead of heat as used in a furnace. The remaining ash representing the miner...

The biochemical and phyto-chemical characteristic of rubber latex (Hevea brasiliensis) was investigated under laboratory conditions. Proximate composition, mineral contents, non-metallic constituents, metallic constituents, phyto-chemical constituents and n-hexane extract components of the latex were analysed. The proximate composition consisted of 60.17 ± 0.01 % moisture, 2.523 ± 0.01 % crude ...

The trend in the industry T H E MINERAL-PROCESSING INDUSTRY is , and will remain, very sensitive to the metal market, which in turn is very dependent on the use of metals for the improvement of lifestyle in developing and developed countries. An assumption is made that the weapons industry will have a reduced effect in the future on the use of metals, and therefore on prices. The cost of metal ...

An inventory of anthropogenic primary aerosol emissions in China was developed for 1990–2005 using a technology-based approach. Taking into account changes in the technology penetration within industry sectors and improvements in emission controls driven by stricter emission standards, a dynamic methodology was derived and implemented to estimate inter-annual emission factors. Emission factors ...

Mineral ions in tap water react with fatty acids in soap, leading to the formation of insoluble precipitate (metallic soap) on skin during washing. We hypothesised that metallic soap might negatively alter skin conditions. Application of metallic soap onto the skin of NC/Tnd mice with allergic dermatitis further induced inflammation with elevation of plasma immunoglobulin E and proinflammatory ...
