Energy efficient processes
Pattern deposition – The deposition of colloidal (nano) particles off an evaporating solvent is used nowadays to generate electronic circuitry and replace the highly polluting and energy intensive processes conducted by photolithography. We use theory and experiment in order to explore the physics of pattern deposition for enabling high resolution and well-defined products.
Stability of colloidal systems (nano-particles) – The extraction of hydrocarbons from underground reservoirs and the treatment and cleaning of soil and water, which were contaminated during this process, require controlling the stability of various suspensions and emulsions. For example, the treatment of water polluted by solid hydrocarbon particles or hydrocarbon emulsion droplets require destabilizing the particulate system in order to support phase separation. Phase separation enables extraction of the polluting agents. Working with experimental groups we use continuum analysis and colloid physics in order to model the stability and dynamics of particulate and interfacial systems.
Electro-polishing – Electro-polishing is an industrial process, employing electrochemistry for polishing metal parts. It was recently found that high frequency acoustic waves, excited in the polished solids increase the efficiency of the electro-polishing process by a factor of two. We model experiments conducted by our colleagues using continuum analysis in order to unravel the physics underlying the acoustic enhancement of electro-polishing.
