Zeta potential is a key physical parameter that describes surface charge on proteins. While measuring the zeta potential of proteins has been a great interest of engineers and scientists for many ...

Intracellular recording of action potentials is important to understand electrically-excitable cells. Recently, vertical nanoelectrodes have been developed to achieve highly sensitive, minimally ...

Current electrochemical theory does not adequately describe realistic platinum electrodes. Scientists at Leiden University ...

THE measurement of membrane potentials in fresh-water protozoa is complicated by the presence of junction potentials existing between the micro-electrode and the medium. These seem to be associated ...

Zeta potential is proportional to the charge on the surface of particles and this value can be used to measure the stability of colloidal dispersions. The larger the zeta potential, the stronger the ...

Researchers have developed ultra-light tattoo electrodes that are hardly noticeable on the skin and make long-term measurements of brain activity cheaper and easier. Researchers have developed ...

By increasing the electron energy in the metal, raising the Fermi level above E0, electrons can be transferred to the acceptor, creating more ions in the reduced state and decreasing the number in the ...

The Large Helical Device (LHD) and the heavy ion beam probe (HIBP) system. The inset on the left shows an enlarged view of the section from the negative ion source to the injection side of the tandem ...

There are many secondary functions associated with designing an electrocardiogram (ECG) signal chain, but one of the most important might be the most underrated: making sure that the electrodes are ...
