The electronic detail of a digital pH-meter
This paperwork presents the complete circuitry used to build a microcontroller-based pH-meter. Key control software is also discussed. An industry-standard glass combination electrode has been employed for pH detection. ...
New methodology for pH measurements in fuel ethanol using glass electrode
Studies carried out with glass electrode in anhydrous ethanol and ethanol-water solutions for measuring pH values have shown that this parameter depends on the solution composition, the contact time with the solution, the ...
pH at the micellar interface: Synthesis of pH probes derived from salicylic acid, acid-base dissociation in sodium dodecyl sulfate micelles, and Poisson-Boltzmann simulation
(Elsevier B.V., 2006-05-01)
The study of the H+ concentration at the micellar interface is a convenient system for modeling the distribution of H+ at interfaces. We have synthesized salicylic acid derivatives to analyze the proton dissociation of ...
Effect of the bath pH on the electrodeposition of nanocrystalline Pd-Co alloys and their magnetic properties
(Elsevier B.V., 2006-11-11)
The effect of the bath pH on the electrodeposition of nanocrystalline Pd-Co alloys and on their magnetic properties was studied. The pH practically did not affect the alloy composition. Conversely, the pH showed a significant ...
Effect of pH on embryonic survival, embryonic and hatching period of Galaxias maculatus

Layer-by-layer films containing SiO2 nanoparticles as field-effect pH sensors
(American Scientific Publishers - ASPValencia, 2013-02)
Devices for pH monitoring based on separative structures and high input impedance readout circuit were fabricated using silicon dioxide nanoparticles (SiO2-Np). SiO2-Np were self-assembled onto gold substrates via ...
An impedance study about the effect of pH on the electron transport rate at poly(o-aminophenol) film electrodes
(Bentham Science Publishers, 2014-06)
Impedance measurements on poly(o-aminophenol) (POAP) film electrodes in solutions of different pH were carried out. Impedance spectra were interpreted in terms of the modified electron hopping model described in F.J. ...
