Physicochemical study of the formation of complexes between pancreatic proteases and polyanions
(Elsevier Science, 2015-08)
The formation of insoluble complexes between proteins and oppositely charged polyelectrolytes was assessed. Two pancreatic enzymes: trypsin and chymotrypsin, and two anionic synthetic polyelectrolytes: polyacrylate and ...
Evidence of the influence of adsorption kinetics on the internal reorganization of polyelectrolyte multilayers
(Elsevier Science, 2011-05)
X-ray reflectivity and adsorption kinetics of two different polyelectrolyte multilayers have been studied for polyelectrolyte multilayers (PEMs) composed of poly(diallyldimethyl ammonium chloride) (PDADMAC) and poly(sodium ...
Electrooptic proprieties of layer-by-layer films of a azobenzene containing copolymer
(2005-12-01)
The methacrylic copolymer functionalized with the azo chromophore 4-[N-ethyl-N-(2-hydroxiethyl)]-amino-2′-chloro-4-nitroazobenzene (MMADR13), in its polyelectrolyte form, can be used to fabricate thin films by the ...

Effect of aluminum sulfate and cationic polyelectrolytes on the destabilization of emulsified wastes
(Pergamon-Elsevier Science Ltd, 2001-01)
Emulsified oil in wastewater constitutes a severe problem in the different treatment stages. Aluminum salts have been traditionally used as coagulants in wastewater treatments. Polyelectrolytes are used to coagulate and ...
Extract of moringa seeds as sugarcane juice flocculant
(Empresa Brasil Pesq Agropec, 2016-10-01)
The objective of this work was to evaluate extractive agents for proteins of moringa (Moringa oleifera) seeds, and the coagulant effect of this protein extract on sugarcane juice for sugar production, which uses acrylamide ...
Charge effect in the interaction of doxorubicin and derivatives with polydeoxynucleotides
(1992-02-11)
The equilibrium interaction of doxorubicin and its N-acetyl derivative with a series of purine-pyrimidine alternating polydeoxynucleotides has been studied through spectrofluorometry to assess the relevance of the electrostatic ...
Bioactive Polyelectrolyte Multilayers: Hyaluronic Acid Mediated B Lymphocyte Adhesion

Estudo da estrutura de complexos de polieletrólitos sobre as propriedades de transporte de água e sais
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2015-03-25)
Polyelectrolytes complexes (PECs) are defined as materials formed by combining oppositely charged polyelectrolytes together via ionic interaction. PECs have some unique physical properties such as non-solubility in common ...
