PVA Nanofibers as an Insoluble pH Sensor
Polymers, 2023 Turmeric has been widely studied as a color indicator for pH variations due to its halochromic properties. It has been tested in solution or included in some polymeric matrices. Some studies have demonstrated that its change in color is due to the tautomeric species of curcumin, and this property can be observed even if turmeric is assimilated in a ...

pH Sensitivity Estimation in Potentiometric Metal Oxide pH Sensors Using the Principle of Invariance
International Journal of Chemical Engineering, 2021 A numerically solvable engineering model has been proposed that predicts the sensitivity of metal oxide- (MOX-) based potentiometric pH sensors. The proposed model takes into account the microstructure and crystalline structure of the MOX material.
