The Nyquist frequency is named after electronic engineer Harry Nyquist. Harry Nyquist was a Swedish-born American electronic engineer who made important contributions to ‘communication theory’ Read more about What is Nyquist?[…]
A rotating disk electrode (RDE) is a hydrodynamic working electrode used in a three electrode system. The electrode rotates during experiments making a constant flux of analyte to the electrode. These working electrodes are used in electrochemical applications such as corrosion studies, fuel cell research, […]
An electrochemical cell consists of two half-cells. Each half-cell consists of an electrode in contact with an electrolyte. An electrode is an electronic conductor such as metal or carbon or a semiconductor. Current flows through the electrodes via the movement of electrons. An electrolyte is a phase in which charge is carried by ions. In Read more about What are Electrochemical Cells?[…]
Batteries are indispensable energy storage systems for mobile and stationary applications. They are mostly used for portable devices or when electrical lines are impractical or impossible.
Their application fields reach from smaller devices such as MP3 players or smartphones up to high power systems for the […]
