Hardening of “22k and 24k gold” for light weighting and high strength Jewelry: Dr. G. S. Vinodkumar and his group

SRMIST involved with Tanishq (Titan) to design:

  • Light weighting jewelry (Bangles and designer chains); High strength jewelry parts (links, stud-claws, pins, which are presently made using 18k gold).
  • Higher Strength with high elasticity and a weight reduction of 30% has been achieved; higher hardness and Scratch resistance; Higher Brilliance than regular 22 K products.
  • Developed a cyanide-free chemical etching technique for 2D & 3D jewelries.
  • Succeeded in developing Anti-tarnishing technology for silver jewelries/items.

“Hard Brass” For Watches Division, Titan Company Ltd. (Scratch and dent resistance): Dr. G. S. Vinodkumar and his group

  • Pilot products made on 25 July 2018, Hardness achieved: 178 to 180 HV

Developed a model for understanding the chirality induced charge transport and nanoscale thermoelectricity in nanodevices: Dr. Arijit Sen and his group

Ptskin@PdPt Nanostructures as Stable and Efficient Electrocatalyst towards Alcohol Oxidation: Dr. Bhalchandra Kakade and his group

A unique and controlled structure of Ptskin@PdPt nanostructures was successfully synthesized showing tremendous enhancement (8-10 times) towards alcohol electrooxidation and oxygen reduction reaction with minimal catalytic poisoning and increased durability than state-of-the-art electrocatalysts.

Fullerene-like BN-60 cages with homonuclear boron bonds: Dr. Ranjit Thapa and his group

BN-60 cages was designed analogue to C60 cage useful for CO oxidation and CO2 hydrogenation. The results are exciting, and Prof. Ranjit believes that they are on the threshold of playing a small but important step in saving the environment from the catastrophic effects of man-made pollution and in developing the next generation catalyst for low-cost green energy production.

Develop Fate Models and quantitative understanding of persistent toxic substances in India: Dr. Paromita Chakraborty and her research group

Complex chemical fate models were used to elucidate: (i) ongoing re-emission of banned pesticide like DDT from Indian soil (ii) informal recycling of electronic waste is acting as a new source for polychlorinated biphenyls in India. For the first time, Lagrangian models has been used on national scale to identify the hotspots and long/short range atmospheric transport of such persistent organic pollutants in India.

Nrf2-based therapies for the treatment of diabetes and its complications: Dr. Ramkumar and his group

Interested in identifying the molecular mechanisms involved in the activation of the Nrf2-ARE signaling pathway by small molecules and its role in various therapeutic interventions such as pancreatic β-cell apoptosis, survival of pancreatic islet grafts and endothelaial dysfunction in diabetes

Hydrogen Bonded Capsules and Thin Films: Dr. S. Anandhakumar and his group

Hydrogen bonded capsules have been fabricated along with thin films based on the use of neutral, non-toxic building blocks. These capsules are interesting carriers for a wide variety of biomedical applications as they have similar ‘stealth’ behavior as PEG based systems, i.e. they are not readily recognized by the immune system, and also can overcome the few draw backs and limitations associated to PEG.

Surface texturing through lithograph patterning for enhanced absorption in solar absorbers: Dr. Malar and her group

Optical absorption enhancement in earth abundant non toxic quaternary absorber material (CZTS) was worked out for solar cells. Light trapping in solar absorber is induced through texturing of the surface of the absorber in contrast to the flat absorber layer surface. Optical lithography tools are used for template assisted growth process to achieve absorber surface with patterned regular array of structures.

Efficient high order entropy satisfying schemes with low viscosity: Dr. Ritesh Kumar Dubey and his group

Proof of sign preserving property at jumps has been established for some of high order efficient reconstruction procedures. They developed a third order accurate class of efficient entropy satisfying schemes with low viscosity for enhanced shock resolution. An extension of this work leading to next generation of shock capturing schemes is going.
