A redox mediator is a hyperbranched polymer having redox moieties (e.g. ferrocene) incorporated into its structure and/or chemically bonded to its periphery. It is attached to an electrode and assists in transferring electrons between the electrode and a redox enzyme.

How does alloying help to reduce corrosion?

Corrosion is a chemical reaction that weakens a metal. It is a redox reaction, to be exact. By creating an alloy, new atoms (or different rations of atoms) are added in the metal being made, which changes the structure of the metal. This can form stronger bonds, which can be resistant to the redox corrosion reaction.Note: Alloys can be made that have a worse resistance to such reactions, but there is no market for them, so they are not sold.


Mixed potential theory?

is a theory used in electrochemistry that relates the potentials and currents from differing constituents to come up with a 'weighted' potential at zero net current. In other words, it is an electrode potential resulting from a simultaneous action of more than a single redox couple, while the net electrode current is zero.


Why HMP shunt called as shunt?

The HMP shunt, or Hexose Monophosphate shunt, is referred to as a "shunt" because it diverts glucose-6-phosphate from the glycolytic pathway to generate NADPH and ribose-5-phosphate. This pathway provides essential reducing power for biosynthetic reactions and helps in maintaining cellular redox balance. The term "shunt" highlights its role in redirecting metabolic flow away from energy production towards biosynthetic and antioxidant functions.


What is a constructive next step when the parties are seemingly stuck in disagreement?

A constructive next step when parties are stuck in disagreement is to facilitate open communication by creating a safe space for each side to express their concerns and perspectives without interruption. Encouraging active listening can help identify underlying interests and common goals. Additionally, seeking the assistance of a neutral mediator may provide fresh insights and guide the parties towards potential compromises or solutions.


Why semiconductors used as photocatalysis?

Semiconductors are used in photocatalysis due to their unique electronic properties, which enable them to absorb light and generate electron-hole pairs upon excitation. These charge carriers can then facilitate redox reactions, allowing for the degradation of pollutants or the conversion of CO2 into useful products. Their tunable bandgap energies allow for optimization of the photocatalytic activity under various light conditions. Additionally, semiconductors are often abundant and can be engineered to enhance stability and efficiency in photocatalytic applications.
