The following are some programs developed by Zhaoxiang Deng during his Ph.D. thesis work with Prof. Xiangqin Lin.

(1) EC-NETSIM 1.0
When used in conjunction with an electronic simulator such as PSpice, this software can serve to simulate virtually any electrochemical problems that can be approximated by Butler-Volmer electron-transfer kinetics coupled with arbitrarily complicated homogeneous chemistry at a planar, spherical, cylindrical or rotating-disk electrode. Simulation of a purely surface-confined process has also been made possible. The basic idea in building this program is to transfer electrochemical problems into electric circuit networks that can be readily solved by an electronic simulation package. Hence at least a free student version of the PSpice package is needed to fulfill basic simulations. Some other programs within the Spice family available on the internet may work for limited cases (in other cases either memory or convergence will be a problem). The author strongly suggests a full version of PSpice (version 5.0 or later) in order to achieve a fully functioning simulator. EC-NETSIM 1.0 is available for free (AS COPYRIGHTED FREEWARE) assuming the program is in its entirety and a specified reference (see following) has been properly cited in any related publications. Note: EC-NETSIM can only help you convert your specific electrochemical problems into PSpice netlist files. Therefore EC-NETSIM is only suitable for those who already or will have access to a PSpice program that can do the rest part of the simulation job for you.

(2) WAVE 98
This is a software that can be used to transfer waveform data from a Tektronix TDS340 digital oscilloscope (should work with other models after minor revisions) to a PC via a standard RS232 port. It was originally built for an ultrafast voltammetric system using TDS340 for high speed data recording.
