Magnetic sol-gel derived poly(oxyethylene)-siloxane nanohybrids
The magnetic and structural properties of sol-gel derived organic/inorganic nanocomposites doped with Fe(II), Fe(III), Nd(III) and Eu (III) ions are discussed. These hybrids consist of poly(oxyethylene)-based chains grafted ...
Vesicle-to-micelle transition in dioctadecyldimethylammonium bromide and dioctadecyldimethylammonium chloride dispersions induced by octaethylene glycol n-dodecyl monoether. An isothermal titration calorimetry study
We have used isothermal titration calorimetry to investigate the vesicle-to-micelle transition in dioctadecyldimethylammonium bromide (DODAB) and chloride (DODAC) vesicle dispersions induced by the nonionic surfactant ...
Studies On Bromelain Precipitation By Ethanol, Poly (ethylene Glycol) And Ammonium Sulphate
(Italian Association of Chemical Engineering - AIDIC, 2011)
Properties of a new poly-ether-glycol copolymer.
(Sociedade Brasileira de Pesquisa em MateriaisCampos do Jordão, 2013-09-29)
Triblock copolymers are made of monomer segments, being the central part usually hydrophobic and the outer parts hydrophilic. By varying sizes, molecular weights and monomer types of the segments one obtains different final ...
Desenvolvimento de sistemas líquido-cristalinos empregando silicone fluido de co-polímero glicol e poliéter funcional siloxano
(Soc Brasileira Quimica, 2009-01-01)
DEVELOPMENT of LIQUID-CRYSTALLINE SYSTEMS USING SILICON GLYCOL COPOLYMER and POLYETHER FUNCTIONAL SILOXANE. For the construction of the phase diagrams, the method of the aqueous titration was used. There were prepared 5 ...
Effects of different mineral supplementations in sheep grazing in Caatinga ecosystem: methane emission.
(In: REUNIÃO ANUAL DA SOCIEDADE BRASILEIRA DE ZOOTECNIA, 52., 2015, Belo Horizonte. Zootecnia: otimizando recursos e potencialidades: anais. Brasília, DF: Sociedade Brasileira de Zootecnia, 2015. 3 f. 1 CD-ROM., 2016)
Polyurethane coating with thin polymer films produced by plasma polymerization of diglyme
(Iop Publishing Ltd, 2009-01-01)
Aqueous-based polyurethane dispersions have been widely utilized as lubricants in textile, shoes, automotive, biomaterial and many other industries because they are less aggressive to surrounding environment. In this work ...
Graphite dispersions as a basis for development of high thermal conductivity fluids
Both conductivity and thermal resistivity measurements of commercial graphite dispersions in non-aqueous polar fluids and non-polar fluids were carried out. Fluids exhibiting different densities as: mineral oil, ethylene ...
