Simple and rapid one-step electrochemical synthesis of nanogranular Cu2O films
(Wiley Blackwell Publishing, Inc, 2018-08)
In the present work, we report a simple experimental strategy for the one-step electrochemical synthesis of nanogranular Cu2O films by copper anodization in fluoride-containing ethylene glycol media. Microscopic exploration ...
Extraction/adsorption as applied to the dearomatization of white mineral oil
(Institution of Chemical Engineers, 2019-03)
Cyclic adsorption units can be considered as an alternative for the regeneration of the solvent being continuously recycled to extraction units. The concept was studied here with an example of dearomatization of mineral ...
Wide range humidity sensors printed on biocomposite films of cellulose nanofibril and poly(ethylene glycol)
(John Wiley & Sons Inc, 2019-09)
Cellulose nanofibril (CNF) films were prepared from side streams generated by the sugarcane industry, that is, bagasse. Two fractionation processes were utilized for comparison purposes: (1) soda and (2) hot water and soda ...
Non-aqueous reverse micelles created with a cationic surfactant: Encapsulating ethylene glycol in BHDC/non-polar solvent blends
(Elsevier Science, 2016-11)
We present results on a new system that forms non-aqueous reverse micelles (RMs) created with a cationic surfactant, benzyl-n-hexadecyldimethylammonium chloride (BHDC), encapsulating ethylene glycol (EG), in different ...
The use of a fatty acid/β-Hydroxyester blend to enhance the surface hydrophilicity of crosslinked poly(ethylene glycol) coatings
(Elsevier Science SA, 2019-10)
By reaction between stearic acid (SA) and a di-epoxidized oligomeric poly(ethylene glycol) under stoichiometric conditions, an amphiphilic β-hydroxyester (β-HE) bearing pendant alkyl chains was obtained with a typical yield ...
Copolymer based on lauryl methacrylate and poly(ethylene glycol) methyl ether methacrylate as amphiphilic macrosurfactant: Synthesis, characterization and their application as dispersing agent for carbon nanotubes
(Pergamon-Elsevier Science Ltd, 2017-02)
The use of amphiphilic macrosurfactants as emulsifying agents has shown to have higher efficiency than that of low molecular weight surfactants. Compared to traditional surfactants, polymeric surfactants have lower critical ...
Nanostructuring of anodic copper oxides in fluoride-containing ethylene glycol media
(Elsevier Science Sa, 2017-12)
We demonstrate that the anodization of copper in alkaline water/ethylene glycol media containing fluoride ions generates nanostructured copper oxide films. By modifying the anodization conditions (fluoride and OH– ...
Synthesis of lauryl methacrylate and poly(ethylene glycol) methyl ether methacrylate copolymers with tunable microstructure and emulsifying properties
(Pergamon-Elsevier Science Ltd, 2019-07)
In this work we study the synthesis and properties of copolymers constituted of lauryl methacrylate and poly(ethylene glycol) methyl ether methacrylate monomers, prepared by atom transfer radical copolymerization in the ...
Stoichiometric production of ethylene glycol from CO and H2 using homogeneous solutions of Mo or W hydride cátions with Rh or Co carbonyl anionsObtenção de etileno glicol a partir de CO e H2 usando soluções homogêneas de hidretos catiônicos de Mo e W com carbonilas aniônicas de Rh e Co
