The SNE is a multi-disciplinary research center that serves the industry in the advancement of surface nano-engineering. At the SNE Research Center, we are working towards developing high-end surfaces, with required properties for practical applications, using state-of-the-art surface nano-engineering techniques.
The research currently being conducted at SNE can be divided into following categories:
- Surface Thermodynamics
- Evaporation Reduction
Our primary focus at the Surface Thermodynamics Lab is studying the fundamentals of surface thermodynamics, and wetting behavior. Interactions between liquids and solids are typically characterized by the contact angle that a liquid drop makes on the solid surface. We change the surface wetting by changing the surface chemistry and roughness through mimicking the hierarchical surface morphology of the lotus leaf.
We can obtain the following desirable surfaces, pending on the applications: Low friction surfaces with application in airfoils, hydrofoils, and pump blades; Anti-icing with application in satellite dishes, and airplane wings; Anti-corrosion with application in Oil and gas industry, metal structures, and ships.

- Preparation of Icephobic Surfaces
- Contact Angle Goniometer and Tensiometer
- Equilibrium of Sessile Drops on Various Geometries: A Numerical Approach
- Improving the Heat Transfer Rate Using Superhydrophobic Coatings in Heat Exchangers
- Transparent Superhydrophobic Coatings
- Corrosion Inhibition of Metals Using Superhydrophobic Technology
- Experimental and Numerical Investigation of Using Superhydrophobic Surfaces on Heat Sink
- Effects of Using Superhydrophobic Microchannels in Electrokinetic Energy Conversion
- Superhydrophobic Coating for Façade of Buildings
- Translucent Superhydrophobic Coating for General Use
At the Evaporation Suppression Lab. we are working on estimating and suppressing the evaporation from dams’ reservoirs. Stationary waters of dams’ reservoirs are highly prone to evaporation. Having more than 640 dams in Iran, and water scarcity issue, we are working on (1) estimating the evaporation rate using GIS technology and satellite images and (2) suppressing the evaporation rate using monolayers.
The developed powder at the Evaporation Suppression Lab., evaporation suppressive monolayer cover (ESMC), forms a monolayer on the water surface and decreases the evaporation rate by up to 60% with no harmful effect on water quality. This powder is designed by modification of the natural microlayers.
