Step-Scan DSC Study on the Melting Behavior of Polypropylene/Attapulgite Nanocomposites
Attapulgite Melt Nano Composite Polypropylene (PP) Recrystallization
2011/11/22
Attapulgite(AT) was modified by grafting with butyl acrylate(BA) via polymerizations initiated by Gamma radiation. The polypropylene(PP)/AT nanocomposites were synthesized via melting extrude in a twi...
One-Step Synthesis of Alkyltrimethylammonium-Intercalated Magadiite
Alkylammomium-Intercalated Magadiite Intercalation Magadiite Organo-Magadiite
2011/12/6
Abstract: Cetyltrimethylammonium- and tetradecyltrimethylammonium-intercalated magadiites were prepared by direct syntheses, starting from sodium metasilicate (Na2O/SiO2 = 1.0) and nitric acid. Total ...
Involvement of genes of the two-step protein secretion pathway in the transport of the manganese-oxidizing factor across the outer membrane of Pseudomonas putida strain GB-1
Involvement of genes two-step protein secretion pathway transport manganese-oxidizing factor Pseudomonas putida strain GB-1
2012/4/1
Microorganisms can accelerate the rate of Mn21 oxidation by up to five orders of mag-nitude compared to abiotic Mn21 oxidation. Mn21 oxidation in Pseudomonas putida strain GB-1 involves an enzyme inco...
