Frequency analysis and resonant operation for efficient capacitive deionization
Ashwin Ramachandran, Steven A. Hawks, Michael Stadermann +1
Capacitive deionization (CDI) performance metrics can vary widely with operating methods. We here develop a theory around and experimentally demonstrate a new operation for CDI tha…
Performance Metrics for the Objective Assessment of Capacitive Deionization Systems
Steven A. Hawks, Ashwin Ramachandran, Slawomir Porada +5
In the growing field of capacitive deionization (CDI), a number of performance metrics have emerged to describe the desalination process. Unfortunately, the separation conditions u…
Thermodynamics of Ion Separation by Electrosorption
Ali Hemmatifar, Ashwin Ramachandran, Kang Liu +3
We present a simple, top-down approach for the calculation of minimum energy consumption of electrosorptive ion separation using variational form of the (Gibbs) free energy. We foc…
Tailored Porous Electrode Resistance for Controlling Electrolyte Depletion and Improving Charging Response in Electrochemical Systems
James W. Palko, Ali Hemmatifar, Juan G. Santiago
The rapid charging and/or discharging of electrochemical cells can lead to localized depletion of electrolyte concentration. This depletion can significantly impact the system's ti…
Capacitive Deionization -- defining a class of desalination technologies
P. M. Biesheuvel, M. Z. Bazant, R. D. Cusick +17
Over the past decade, capacitive deionization (CDI) has realized a surge in attention in the field of water desalination and can now be considered as an important technology class,…
Isotachophoresis applied to chemical reactions
Charbel Eid, Juan G. Santiago
This review discusses research developments and applications of isotachophoresis (ITP) to the initiation, control, and acceleration of chemical reactions, emphasizing reactions inv…
