Controlling Foam Stability with the Ratio of Myristic Acid to Choline Hydroxide
(American Chemical Society, 2018-09)
The interfacial and foam properties of a model system based on the mixture between myristic acid and choline hydroxide have been investigated as a function of the molar ratio (R) between these two components and temperature. ...
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 pH-responsive foam formulated with PAA/gemini hernán martinelli 12-2-12 complexes
(MDPI AG, 2021-07-19)
In the search for responsive complexes with potential applications in the formulation of smart dispersed systems such as foams, we hypothesized that a pH-responsive system could be formulated with polyacrylic acid (PAA) ...

Effective Electromechanical Coupling Coefficients of Piezoelectric Adaptive Structures: Critical Evaluation and Optimization
(TAYLOR & FRANCIS INC, 2009)
This work presents a critical analysis of methodologies to evaluate the effective (or generalized) electromechanical coupling coefficient (EMCC) for structures with piezoelectric elements. First, a review of several existing ...
Remote radiofrequency triggering of topography changes in a surface micropatterned PANI@PNIPAM nanocomposite
(Elsevier Science, 2020-04)
The presence of polyaniline (PANI) conducting polymer loaded in thick films of a transparent and thermosensitive poly(N-isopropylacrylamide) (PNIPAM) hydrogel network allowed for absorption of UV light and modification of ...
