Resilient water treatment technologies and challenges for the removal of emerging contaminants – Perfluorinated compounds

Singh R., Singh T.S., Singh R., Singh T.S., University of Virginia, US

Due to their global presence, persistence, and adverse health effects, perflurinated compounds (perfluoroalkyl and polyfluoroalkyl substances PFASs) have become major chemical of concern for drinking water supplies worldwide. Presence of these PFCs in various geographical [...]

Insect Fouling on Superhydrophobic Surfaces

Krishnan K., Milionis A., Tetteh F., Loth E., University of Virginia, US

An experimental setup consisting a wind tunnel and insect delivery system that is capable of injecting insects at 100 mph was built to test the effectiveness of superhydrophobic coatings towards insect fouling. Three distinct components [...]

Elastic Superhydrophobic Nanocomposites with Enhanced Mechanical Durability

Milionis A., Languasco J., Loth E., Bayer I.S., University of Virginia, US

The vast majority of superhydrophobic surfaces are very fragile which is their main limiting factor for commercialization. Improving their mechanical durability has been a major issue during the last years. In this work we demonstrate [...]

Microscopic “Slide-Snap” Receding Contact Line Dynamics on Superhydrophobic Surfaces

Yeong Y.H., Milionis A., Bayer I.S., Loth E., University of Virginia, US

Receding angles have been shown to have great significance when designing a superhydrophobic surface for applications involving self-cleaning. Although apparent receding angles under dynamic conditions have been well studied, the microscopic receding contact line dynamics [...]

Mechanically Durable Superhydrophobic Nanocomposites from Acrylonitrile Butadiene Styrene (ABS)

Milionis A., Yeong Y.H., Loth E., Bayer I.S., University of Virginia, US

We report on the development of nanocomposites based on a combination of ABS with hydrophobically modified fumed silica (HMFS). By tuning the ratio between the two materials we are again able to obtain static water [...]

Superhydrophobic 3D Printed Surfaces by Dip-Coating

Milionis A., Loth E., Bayer I.S., University of Virginia, US

Here we demonstrate a technique to fabricate three-dimensional superhydrophobic patterns. First a three-dimensional pattern was designed by 3D printing using acrylonitrile butadiene styrene (ABS) as printing material. A linear printing algorithm is followed for the [...]
