Totally organic redox active pH sensitive nanoparticles stabilized by amphiphilic aromatic polyketones
(American Chemical Society, 2018)
Amphiphilic aromatic polymers have been synthesized by grafting aliphatic polyketones with 4-(aminomethyl)benzoic acid at different molar ratios via the PaalKnorr reaction. The resulting polymers, showing diketone conversion ...
Effect of surfactant concentration on the responsiveness of a thermoresponsive copolymer/surfactant mixture with potential application on “Smart” foams formulations
(Academic Press Inc Elsevier Science, 2018-02)
Hypothesis Previous efforts to formulate smart foams composed of mixtures of PNIPAAm, a thermoresponsive uncharged polymer, and surfactants have failed because the surfactant displaces the PNIPAAm from the liquid-air ...
A quantum molecular dynamics study of aqueous solvation dynamics
(American Institute Of Physics, 2013-10-23)
Ring polymer molecular dynamics experiments have been carried out to examine effects derived from nuclear quantum fluctuations at ambient conditions on equilibrium and non-equilibrium dynamical characteristics of charge ...
Microesferas biodegradables de quitosano/carboximetilcelulosa obtenidas mediante gelación iónica para liberación lenta de KNO3
(Universidad Michoacana de San Nicolás de Hidalgo, 2022-12)
One of the main strategies implemented worldwide to address global food shortages is the use of agrochemicals, however, in conventional formulations the active ingredient is released immediately, leading to degradation ...
Determinação por cromotografia em fase gasosa de aminoácidos livres em salames submetidos a ultrassom
(Universidade Federal de Santa MariaBRCiência e Tecnologia dos AlimentosUFSMPrograma de Pós-Graduação em Ciência e Tecnologia dos Alimentos, 2015-03-12)
Amino acids are organic compounds abundant in animal tissues, especially in meat and meat products, in free form or polymers, participating in biochemical reactions and may be precursors of compounds of interest in the ...
Baterías recargables con energía solar, basadas en polímeros nano-estructuradosRechargeable batteries with solar energy, based on nano-structured polymers
(2017)
El déficit energético actual y la contaminación a nivel mundial, han favorecido una nueva revolución, con miras a la generación de energía a partir de fuentes inagotables y limpias para el medio ambiente. Esto ha conllevado ...
