a. Wetting of soft deformable surfaces This research area focuses on understanding the interactions of liquid drops with soft, deformable substrates. On substrates that deform under the action of the surface tension forces of the liquid drops, an intriguing interplay of the solid-liquid interactions ensure different static and dynamic behaviors of the liquid drops. The […]
a. Charged surfaces, EDL theory and electrokinetics In this topic, we explore the behavior of nanoscale charged surfaces and the transport and liquids and ions (through electrokinetics) triggered by the interactions of these surfaces with liquids and ions. The applications of the topic range from better exploiting nanoscale physics for augmented nanoscale transport to developing

3-D Printing refers to ability to carry out additive manufacturing in 3-D space. SMIEL is extensively involved with 3-D printing of electronics and composites on conformal surfaces by using commercial and in-house-fabricated inks as well as developing the central thermo-fluidic and thermo-mechanical understanding involved in different 3D processes. Collaborators: Dr. Dan Hines (LPS), Prof. Abhijit
