Our research focuses on the development of novel metals and alloys for advanced applications. We aim is to identify the failure mechanisms for different materials under the use conditions through structure-property correlation. This knowledge is then used to improve the performance through material design viz. alloy development, microstructure engineering, coatings, etc. while ensuring a viable manufacturing process.

• Typically synthesized through the dissolution of a less noble metal from a binary alloy
  • Possesses extremely high specific surface area
• Research focus: Fracture mechanisms in nanoporous metals
  • Applications in actuation, catalysis, biosensing, and super-capacitors

Strain field measured through DIC and high-speed camera 4.34µs/frame

• High strength owing to small grain size
• Research focus: Thermally stable, high conductivity, and fatigue resistant nanocrystalline alloy development through electrodeposition
  • Anti Hume-Rothery rules to develop binary immiscible alloy systems with the alloying element(s) segregating at the grain boundaries to provide grain stability
  • Applications in infrastructure as coatings and MEMS devices

• Inherent part of electronic devices; critical properties include conductivity, electromigration, thermal fatigue, and high strain rate fracture
• Research Focus: High reliability manufacturing friendly interconnect alloy development including Sn-Bi based low temperature solders, Ag sintering, Cu-Cu bonding etc.
  • Applications in electronic devices

• Research focus: Development and optimization of electrodeposited porous copper through DHBT electrodeposition for tunable porosity, enhanced capillary wicking, surface wettability, efficient heat dissipation, and mechanical reliability.
• Application in Immersion cooling systems for high-power electronics, EV batteries.
