(Association of Chemical Engineers of Serbia, 2013)
Composites based on unsaturated polyester (UPe) resins and fumed silica AEROSIL® RY 50, NY 50, RX 50 and NAX 50, as well as graphite, TiO2 or organically modified clay CLOISITE 30B were prepared in order to investigate the ...
A thin layer chromatographic comparison of raw and soluble starch hydrolysis patterns of some alpha-amylases from Bacillus sp isolated in Serbia
(Serbian Chemical Soc, Belgrade, 2014)
Several natural isolates of Bacillus strains namely 5B, 12B, 16B, 18 and 24B were grown at two different temperatures in submerged fermentation for the production of raw-starch-digesting alpha-amylases. All strains except ...
Reuse of waste sulfur as a binding agent in concrete
(Association for Promotion of Holistic Approach to Environment, 2018)
Mainly due to the strict global environmental regulations regarding the oil and gas
refining processes, which limit the maximum quantity of sulfur in combustibles, the
availability of waste sulfur has been considerably ...
Possible use of ground sulfur as petroleum industry byproduct in self-compacting concrete production
(Association for Promotion of Holistic Approach to Environment, 2018)
The quantities of component materials used for production of concrete are high on the
global scale, therefore alternative materials are experimented on, in order to replace the
natural ones. The possibility of using ...
