Research Interests:
Structure-property-co-relationship of Graphene-based composite materials for energy research:
Graphene, the two-dimensional (2D) nano-allotropes of carbon consisting of single-layer of sp2 carbon atoms have drawn tremendous attention in academic as well as industrial R & D in last more than one decade or so; due to its’ unique properties such as high surface area, excellent electrical conductivity, superior thermal & mechanical strength and related properties. Interestingly, in recent days assembly of 2D graphene sheets into high-surface area hollow spheres has drawn again significant attraction of this wonder material due to its’ potential eligibility in the broader application areas ranging from catalyst support to drug-delivery and specially major emphasis in the field of energy storage where fabricating electrode materials with graphene for energy storage devices such as super capacitors and batteries has become a major thrust in this research area and great amount of attentions have been employed in this particular research field is also on the possibility of assembly of 2D graphene sheets into hollow spheres for developing core/shell structure composites also for this particular applications. In this proposed research plan; micro-structural, functional aspects as well as potential usage of these Graphene-based composite materials in energy storage devices will be explored in great details.
Metal-organic/organo-metallic precursor based electronics materials development:
Availability of conventional metallic particle based pastes such as Silver (Ag) and Copper (Cu) based pastes in sinterable electronics paste market have come out one of the excellent alternatives for Sn-based traditional die-attach materials suitable for Wide Band-gap Semi-conductor (WBG) devices. Submicron/nano Cu particle based sintering pastes have certain advantages such as lower cost and better electrochemical migration reliability than the corresponding Ag particle pastes although their corresponding sintered joints possess similar mechanical, electrical and thermal properties. But, the major drawback of Cu particle based pastes is the intrinsic oxidation tendency of Cu particles in ambient condition; hence hindering the effective sintering of Cu particles. Performing die-attachment with particle based Cu sintering paste at high sintering temperature such as 400 °C with high pressure under reducing forming gas either inert argon, nitrogen or formic acid environment might lead to higher shear join strength; unacceptable for practical application due to these harsh and complicated sintering conditions. This proposed research strategy would give a solution to this above mentioned challenges which involves a metal-organic or organo-metallic precursor based printable Cu paste/ink which should eliminate most of the obstacles encountered during the electronics assembly process using conventional market available Cu based printable electronics paste.
Fabrication of Graphene & allied 2-D advanced materials based product development for electronics industry:
Commendable mechanical properties namely Elastic modulus, Hardness along with superior in-plane thermal conductivity of Graphene & related 2-D advanced materials can be potentially leveraged for the development of flexible, mechanically strong polymer composite materials for effective heat dissipation while electronics gadgets are in use. These advanced materials-polymer composite based thermal management materials has certain assembly and end-user usage advantages over conventional metallic thermal management materials used for this purpose in electronic gadgets; will be explored and studied in great detail in this proposed research sketch.
