What measurable physical properties allow one to distinguish surfactant-stabilised from Pickering emulsions? Whereas surfactants influence oil/water interfaces by lowering the interfacial tension, particles are assumed have little effect on tension. Here we perform tension (IFT) measurements three different systems: (1) soybean oil and water with ethyl cellulose nanoparticles (ECNPs), (2) silicone globular protein bovine serum albumin (BSA), (3) sodium dodecyl sulfate (SDS) solutions air....
This article deals with the behavior of fluids inside a reflective display based on electrowetting. The advantage using electrowetting as principle for has been demonstrated [R. A. Hayes and B. J. Feenstra, Nature (London) 425, 383 (2003)]. is controlled two-dimensional movement an oil/water interface across hydrophobic fluoropolymer insulator. main objective this to show experimentally influence oil film curvature kinetics optical switch. For we explore fluidic motion function several...
Mesoporous titania with a high mesopore ordering and surface area have been synthesized by new surfactant templating process that combined both the evaporation-induced self-assembly method liquid crystal pathway. The precipitation of in hybrid mesophase is activated an NH3 treatment. We investigated influence concentration surfactant/titanium precursor (TiOPr) molar ratio on properties mesostructured titania. recovered materials characterized SAXS measurements, nitrogen adsorption–desorption...
Polymer flooding is one of the enhanced oil recovery (EOR) methods that increase macroscopic efficiency process and crude recovery. In this study, effect silica nanoparticles (NP-SiO2) in xanthan gum (XG) solutions was investigated through analysis core tests. First, viscosity profiles two polymer solutions, XG biopolymer synthetic hydrolyzed polyacrylamide (HPAM) polymer, were characterized individually rheological measurements, with without salt (NaCl). Both found suitable for at limited...
In this study, the effective removal of three major micropollutants (e.g., propranolol hydrochloride, 1-naphthylamine, and 2-naphthol) from water is investigated using defected UiO-66 functionalized derivatives as adsorbents. The defects in are induced two distinct strategies. first one involves a process selectively thermolyzing labile linkers, leading to creation hierarchical mesoporous framework (HP-UiO-66). second technique employs monocarboxylic acid modulator, such acetic (AA) or...
Abstract We report on the preparation and photophysical structural characterization of alloyed CdSe(S) nanocrystals, which are covered by a ZnO shell. QDs were prepared reaction CdCl 2 with NaHSe in presence 3‐mercaptopropionic acid (MPA) under hydrothermal conditions. The incorporation sulfur arises from surface‐mediated MPA hydrolysis growing QD surface. Water‐dispersible successfully capped shell obtained basic Zn(OAc) . experimental results transmission electron microscopy (TEM) imaging...
This study aimed to investigate the effects of sludge retention time (SRT), hydraulic (HRT), and biomass concentration (CTSS) in activated systems on removal various micropollutants (MPs), covering a wide spectrum biodegradability. The influence classical pseudo-first-order rate constant was verified. Results showed that constants were affected by both HRT SRT. enhancement SRT increased all MPs except for two macrolide antibiotics. Application higher also improved MP removal, as expected...
In this study, we investigate the flow behavior of oil-in-water Pickering emulsions stabilized with bovine serum albumin (BSA). Through use a phase transition analogy and scaling parameters previously applied to surfactant-stabilized emulsions, successfully describe behavior, suggesting remarkable similarity in rheology these emulsion categories. Additionally, explore possibility extending modeling framework oscillatory mode. Above jamming fraction, scaled data regime present similar trend...
Recently, we have demonstrated reflective display pixels based on the voltage-controlled two-dimensional movement of an oil/water interface across a hydrophobic fluoropolymer insulator [R. A. Hayes and B. J. Feenstra, Nature (London) 425, 383 (2003)]. Here physical model is reported that describes basic electro-optic behavior these electrowetting-based optical elements. The extends classical electrowetting theory developed for free water droplet surface to controlled confined interface....
