(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Ciência e Engenharia de MateriaisCâmpus São Carlos, 2018-09-24)
Poly(lactic acid) (PLA) was modified with maleic anhydride (MA) or glycidyl methacrylate (GMA) in the presence of peroxide to assess the physical and chemical changes of the polymer during the reactive processing. Chemical ...
Structural and functional characterization of BnSP-7, a Lys49 myotoxic phospholipase A(2) homologue from Bothrops neuwiedi pauloensis Venom
(Academic Press IncSan DiegoEUA, 2000)
Myotoxic phospholipases A2 in Bothrops snake venoms: Effect of chemical modifications on the enzymatic and pharmacological properties of bothropstoxins from Bothrops jararacussu
Venoms from eight Bothrops spp. were fractionated by ion-exchange chromatography on CM-Sepharose at pH 8.0 for the purification of myotoxins. Chromatographic profiles showed differences regarding myotoxic components among ...
Siloxanes synthesized “in situ” by sol–gel process for fire control in wood of Araucaria angustifolia
Panels of Araucaria angustifolia were chemically modified with alkoxysilanes, hydrolyzed and condensed “in situ” by the sol–gel process. Alkoxysilanes selected were aminopropyl methyldiethoxysilane (A), aminopropyl ...
