Direct visualization of viscous dissipation and wetting ridge geometry on lubricant-infused surfaces (2024)
Journal Article
Naga, A., Rennick, M., Hauer, L., Wong, W. S. Y., Sharifi-Aghili, A., Vollmer, D., & Kusumaatmaja, H. (2024). Direct visualization of viscous dissipation and wetting ridge geometry on lubricant-infused surfaces. Communications Physics, 7(1), Article 306. https://doi.org/10.1038/s42005-024-01795-3

Drops are exceptionally mobile on lubricant-infused surfaces, yet they exhibit fundamentally different dynamics than on traditional superhydrophobic surfaces due to the formation of a wetting ridge around the drop. Despite the importance of the wetti... Read More about Direct visualization of viscous dissipation and wetting ridge geometry on lubricant-infused surfaces.

Wetting on silicone surfaces (2024)
Journal Article
Hauer, L., Naga, A., Badr, R. G. M., Pham, J. T., Wong, W. S. Y., & Vollmer, D. (2024). Wetting on silicone surfaces. Soft Matter, 20, 5273-5295. https://doi.org/10.1039/d4sm00346b

Silicone is frequently used as a model system to investigate and tune wetting on soft materials. Silicone is biocompatible and shows excellent thermal, chemical, and UV stability. Moreover, the mechanical properties of the surface can be easily varie... Read More about Wetting on silicone surfaces.

Designing Plastrons for Underwater Bubble Capture: From Model Microstructures to Stochastic Nanostructures (2024)
Journal Article
Wong, W. S. Y., Naga, A., Armstrong, T., Karunakaran, B., Poulikakos, D., & Ras, R. H. A. (2024). Designing Plastrons for Underwater Bubble Capture: From Model Microstructures to Stochastic Nanostructures. Advanced Science, 11(33), Article 2403366. https://doi.org/10.1002/advs.202403366

Bubbles and foams are often removed via chemical defoamers and/or mechanical agitation. Designing surfaces that promote chemical‐free and energy‐passive bubble capture is desirable for numerous industrial processes, including mineral flotation, waste...

Polarity-Induced Reactive Wetting: Spreading and Retracting Sessile Water Drops. (2024)
Journal Article
Wong, W. S. Y., Kiseleva, M. S., & Naga, A. (2024). Polarity-Induced Reactive Wetting: Spreading and Retracting Sessile Water Drops. Langmuir, 40(26), 13331-13752. https://doi.org/10.1021/acs.langmuir.4c01085

Wetting is typically defined by the relative liquid to solid surface tension/energy, which are composed of polar and nonpolar subcontributions. Current studies often assume that they remain invariant, that is, surfaces are wetting-inert. Complex wett...
