Welcome to SMNL
Our research is aimed to develop various advanced functional nanomaterials for energy, polymer composites, biomedical and environmental technologies. In addition to materials development, our research also focused on the development of new device systems as well as products, which will create a significant impact on our society in near future. Ultimately our multi-disciplinary research activity is focused to develop a wide range of functional nanomaterials employing various agro and forestry resources as the feedstock for the diversified applications. At present we have committed to extend my research expertise to convert renewable resource based biomass into various high value nanomaterials for future technologies. We have excited about what the nature can offer to our society and my ambition is to be a leading layers in utilizing the natural resources for the future materials world. Thank you for visiting our website. With best regards, Vivekanandhan |

Interesting candidates are requested to contact the lead researcher through email with the full length CV.
Highlights
Soy leaf extract mediated bio reduction process has been successfully employed for the decoration of graphene with silver nanoparticles. Silver content on the graphene sheets has been varied by manipulating the silver nitrate concentration in the reaction mixture. It has been found that the silver nanoparticles deposited on the graphene sheets were exist in diameter range of 2-25 nm.

Chemical modification of lignin precursor is one of the key activities in structuring the final products. Interestingly, glycerol has been used as the plasticizing agent to lignin and influences their carbonization behavior, which results Carbon Nano Sponge. Due to the unique structural properties they could be used in lithium batteries, super capacitors and respirator filers.

LiMn2O4 nanorods were successfully synthesized by modified polymeric precursor route followed by the controlled calicnation. SEM analysis confirmed the formation of LiMn2O4 nanorods through the controlled calcinations and the synthesized LiMn2O4 nanorods were found to be ~1µm length and ~50-75nm diameter.

A simple and facile hydrothermal process was explored for the preparation of green-emitting graphene oxide-carbon dot composite from brown macroalgal biomass-derived bio-oil as carbon source. The brown macroalgal bio-oil-derived graphene oxide-carbon dot composite was effectively explored to enhance the seed germination properties of mung bean seeds, which also enhanced the plant growth.

Jatropha oilcake (JOC), a major agro industrial co-product was effectively converted into activated carbons employing KOH mediated chemical process for supercapacitor applications. The activated carbons were synthesized by employing conventional (CC) as well as hydrothermal carbonization (HTC) processes.
|
The Periconia sp. extract mediated sol-gel process was effectively utilized for the synthesis of ZnO nanoparticles. The aqueous fungal extract acted as chelating agent for the Zn2+ ions and lead to the formation of gel. The synthesized ZnO nanoparticles exhibited excellent antimicrobial activity. Further, it also exhibited good antioxidant property.
