The effects of different contents of impurities and seed hulls in the raw material on the sensory characteristics, chemical quality, and oxidative stability of sunflower oil prepared by the procedure ...
Subsurface impurities and vacancies in a three-dimensional topological insulator
Subsurface impurities vacancies three-dimensional topological insulator
2012/2/24
Using a three-dimensional microscopic lattice model of a strong topological insulator (TI) we study potential impurities and vacancies in surface and subsurface positions. For all impurity locations w...
Chemical specifications for high purity gold have grown increasingly stringent as manufacturers strive to improve quality control. Once 999.9-fine grain and bullion bars were accepted without question...
Biological Removal of Impurities from Textile Industry Wastewaters: An Assessment
textile industry water wastes biodegradation activated sludge
2009/2/8
Textile wastewaters (WW) contain specific impurities that impede their biological treatment. Thus, to be treated biologically, they require technological pre-treatment, mostly composition equalisation...
Analyses of impurities in cast magnesium-rare earth elements alloys
Magnesium alloy Rare earth elements Microstructure
2011/3/17
Microstructure analyses of impurities in binary Mg–3%RE and Mg–8%RE alloys are presented. Light microscopy and scanning electron microscopy (SEM+EDX) techniques were used to characterize the investiga...
Neps, Seed-Coat Fragments, and Non-Seed Impurities in Processed Cotton
Non-Seed Impurities Seed-Coat Fragments Neps
