This book discusses the merging of nanoscale electronics and electrochemistry and how this can
potentially modernize the way electronic devices are currently engineered or constructed. It
introduces the electrochemical capacitance as a fundamental missing concept that solves the
puzzle between molecular electronics and electrochemistry at the nanoscale. The electrochemical
capacitance as a fundamental principle is deduced from first principles quantum mechanics.
The text also confirmed that faradaic and non-faradaic processes are only different physical
approximations of the same sort of energetic phenomenon.The book comprises three chapters.
Chapter one introduces the concepts of chemical capacitance relaxation resistance and the
quantum resistive-capacitive circuit and demonstrates how these elements are translated to the
electrochemistry context. In chapter two the chemical capacitance the fundamental concept and
missing part of the puzzle that unity electronics and electrochemistry is deduced from first
principles of quantum mechanics. In chapter three the concepts are practically used in
different contexts that include molecular diagnostics molecular conductance and
super-capacitive phenomena is explained using the introduced basic principles.
