Symmetric cell for improving solid-contact pH electrodes

Analytica Chimica Acta, 2023
Traditional pH glass electrodes are designed in a symmetrical manner to guarantee the most reliable and reproducible potentiometric measurements possible. Solid-contact and other pH probes not based on glass membranes are desirable because they allow for new types of applications, may be mass fabricated and less prone to breakage.

Solid-contact ion-selective electrodes based on ferrocene-functionalized multi-walled carbon nanotubes

Electrochemistry Communications, 2021
Solid contact materials based on hydrophobic conductors with a large surface area and high double-layer capacitance (e.g. nanostructured materials) have been reported to provide excellent potential stability to ionophore-based solid-contact ion-selective

Computation of the drag force on a rough sphere close to a wall [PDF]

, 2011
We consider the effect of surface roughness on solid-solid contact in a Stokes flow. Various models for the roughness are considered, and a unified methodology is given to derive the corresponding asymptotics of the drag force.

Study on thermal contact resistance at liquid–solid interface based on fractal theory

AIP Advances, 2021
The study of the thermal contact resistance at the liquid–solid interface is an important subject of the heat transfer of phase change materials. In this work, a fractal model for predicting the thermal contact resistance at the liquid–solid interface is

Pickering emulsions stabilized by hydrophilic nanoparticles: in situ surface modification by oil [PDF]

, 2016
We propose a novel route for the stabilization of oil-in-water Pickering emulsions using inherently hydrophilic nanoparticles. In the case of dialkyl adipate oils, in situ hydrophobisation of the particles by dissolved oil molecules in the aqueous phase ...
