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.
What function of java server pages?
Java Server Pages have become an integral part of any J2EE application. They are used extensively because they can combine the features of HTML and Java. The difficulty level of JSP is half-way between HTML and pure Java. For simple tasks like displaying the current date, you write a normal HTML page and add only a small amount of Java as a scriptlet. For big tasks like processing a shopping cart, you use JSP as the mediator between the Web form and a component (Ex: Servlet) that has all the processing logic. CGI, Perl, Active Server Pages etc were all the predecessors of Java Server Pages. Am not saying that the JSP Technology was built based on these technologies but it is safe to say that, the JSP Technology was created to overcome many of the shortcomings in the above mentioned technologies. Though the ASP technology is a web server scripting champion and is used very widely, the only problem is the Runs only in Windows Attitude of the technology. Unlike ASP, JSP has equivalent if not better features and can run in any environment making it an invaluable tool for enterprise application developers who don't want to be tied to the limitation of the system running only in Windows. Not only does JSP run on all major platforms, but the JavaBeans used by these JSPs run on all major platforms as well. JSP competes directly with ASP. In fact, you would be forgiven if you thought it was a copy. Sun took the same approach to JSP as it did with Java. Sun borrowed the syntax of its best competitor (ASP for JSP and C++ for Java) tweaked it a little, but built everything under the hood from scratch. Java syntax comes from C++, but it works on all platforms with no portability issues like C++ for the developer. Similarly, the JSP structure comes from ASP. The look and feel, and even some syntax is the same. However, ASP primarily uses Microsoft's versatile VBScript, while JSP uses the more powerful and portable Java and JavaScript.
What is over voltage in electrochemistry?
In electrochemistry, overvoltage is synonymous with overpotential. Look up overpotential instead of overvoltage to get details of what it is. Basically, it is a potential that develop because of limited reaction kinetic. It works to reduce the voltage of the electrochemical cell. Think of it like this. For a given redox reaction pair that represents a chemical cell, it has a theoretical voltage determined by thermodynamics. This is typically called the open cell voltage. It's the maximum voltage that you could harness out of this reaction if you were to make this into a battery. That is all very good and all except for the little detail of reaction kinetics. In reality, you don't ever get the maximum voltage at open cell. Once current start flowing, limitations on rate of reaction at the cathode and anode develop. Reactions are not infinitely fast. Once you start the reaction, the region near the electrodes are depleted of ion species as they are oxidized or reduced into and out of the electroloyte. It takes time for more to diffuse from the bulk to the solution to the electrode/electrolyte interface. Now your reaction rate is limited. This limitation will show up as a potential, the overpotential, at the electrode. It acts to reduce the potential available to you across the entire cell. If your open cell potential of a batttery was say 2 volts, you may find a severely rate limited reaction to generate 1.9 volts of overpotential at the electrodes as you try to draw current out of the battery. When that happens, your cell actually only gives you 0.1 volts, not 2 volts. What I described above is called concentration overpotential. There are other sources of overpotential. It is much beyond the scope of Y:A to describe it. However, the phenomenon of overpotential in an electrochemical cell is a consequence of reaction kinetics. There are other concepts like equilibrium exchange current density and the use of the Tafel plot when you delve into the topic of electrochemical cells. These are things that must be considered in addition to the thermodynamic open cell potential when a cell starts to draw a current. The best batteries will be constructed out of a system in a way as to have high exchange current density and minimum overpotential. So as you draw current from the cell, you don't find yourself with vastly diminished voltage. It's ability to do work will not be self-limiting as you put it in a device that draws current.
