SUMMARY

The discussion focuses on deriving Fick's law of diffusion in the context of electrochemical sensing. The key equation presented is I = Jmf, where I represents current, J is the flux, m denotes the number of electrons, and F is the Faraday constant. The relationship I = nAve is also highlighted, with n as the number of charge carriers per volume, A as the cross-sectional area of the sensor, and e as the charge of an electron. Participants are encouraged to explore external resources for further understanding.

PREREQUISITES
  • Understanding of Fick's law of diffusion
  • Knowledge of electrochemical sensing principles
  • Familiarity with current density and flux concepts
  • Basic grasp of Faraday's laws of electrolysis
NEXT STEPS
  • Study the derivation of Fick's law of diffusion in detail
  • Explore electrochemical sensor design and functionality
  • Learn about current density calculations in electrochemical systems
  • Investigate the role of charge carriers in electrochemical reactions
USEFUL FOR

Researchers, electrochemists, and students in materials science or chemical engineering focusing on electrochemical sensing applications.

Anyone knows how to derive Fick's law of diffusion:

I=Jmf

Given current density applied to electrochemical sensing:
I= nAve

where :
I=current
J=flux
m=number of electrons
F=faraday constant
v=speed of particles
n=number of charge carriers/vol
A= cross-sectional area of sensor(electrode)
e=charge of an electron


Please help, at least give a clue where to start and the procedings.
Thanx
