Tuning Solid-Liquid Interfaces at Micro and Nano Scales
Tuning solid-liquid interfaces at micro and nano scales is a rapidly developing field with a wide range of potential applications. By modifying a solid's surface chemistry or topography, it is possible to change its wettability, adhesion, and other properties. Tuning solid-liquid interfaces at the micro and nano scales is already being used in a variety of applications, such as self-cleaning coatings, microfluidic devices, wettability sensors, heat transfer devices, self-assembly applications, catalysts, and thermal management devices.
Problem 1: Evaporation and Leidenfrost effect on Graphene surface, Molecular dynamics study: Thermal transport
Graphene's unique properties affect evaporation and the Leidenfrost effect, which can be used to create novel applications such as self-cleaning surfaces, antifouling coatings, and microfluidic devices. For example, a graphene surface with a Leidenfrost effect can repel water droplets or handle liquids at high temperatures Status: On-going
Problem 2: Thermodynamically Optimised Heat Sink
Thermodynamically optimized heat sinks enhance heat transfer, energy efficiency, and reliability in electronic devices by optimizing shape, materials, and surface qualities.
Status: On-going
Problem 3: Coalescence of Saltwater Droplets Dispersed in Crude Oil: Coupled Effects of Fluid Rheology and Electric Field
Coalescence of saltwater droplets in crude oil is a complex process affected by fluid rheology and electric field. Fluid rheology governs the flow of oil and water, while electric field induces attractive forces between droplets. By understanding the coupled effects of these factors, we can develop new strategies to enhance oil-water separation.
Status: Published. FMFP2022–8168
Problem 4: Self Propulsion of droplets
Self-propulsion of droplets involves harnessing surface tension, chemical gradients, or external energy sources to enable droplets to move autonomously. This phenomenon has applications in microfluidics, lab-on-a-chip devices, offering precise control and efficiency.
