Jul 1, 2020 · The main objective of the present work is to investigate the competitive mechanisms of phase separation and gel formation by simply adjusting the pH of GA/HPMC blend, which …

All gel formulations showed acceptable physical properties concerning color, homogeneity, consistency, spreadability and pH value. These gel formulations were further compared with …

To explore the influence of pH values on the properties of a compound system containing tea polyphenols (TPs) and low acyl gellan gum (LGG), the color, texture characteristics, …

Jun 15, 2023 · Herein, we report the influence of pH on mechanical properties as studied by texture analysis supported by data from polarimetry, zeta potential, pH titrations and NMR …

Oct 14, 2023 · Gelation, the process by which a liquid transforms into a gel, is heavily influenced by pH. At the molecular level, pH changes can alter polymer networks and molecular …

Feb 11, 2011 · An increase in pH led to the formation of a reduced number of junction zones and a decrease in molecular aggregation, reducing gel rigidity. On the other hand, this structure …

Amongst stimuli sensitive hydrogels, pH sensitive hydrogels have been widely studied and used in biomedical applications especially in drug delivery applications exploiting the pH variation …

Jan 10, 2025 · For instance, when the pH was lowered from neutral conditions (pH 7) to acidic conditions (pH 2), the initial gelation time extended from 20 to 52 min. Our findings revealed …

May 24, 2016 · Modification of the pH during the sol-gel process, is necessary to catalyse the hydrolisys of the alkoxy moieties (for example: CH 3 CH 2 O- groups) which is then followed …

We apply a multiscale approach to examine the structural hierarchy, phase behavior and equilibrium properties of DNA gels. Here we report SANS and osmotic pressure …
