- Title:Graphene and Graphene Like Nano-Dimensioned Materials for Diagnostic Applications
- Time :
Graphene, the wonder material is just one of the many 2-D materials that have been discovered now. In constant efforts to improve the properties of the graphene, many new graphene-like materials have been developed such as graphane, fluorographene, white graphene, and various other forms of graphene (oxides, quantum dots, ribbons, coils, pillars and fibers). These graphene like or graphene based materials are the most studied and researched because of their excellent optical and electronic behavior as both these properties are of utmost importance while considering diagnostic applications. These have been used as biosensing platforms, anti-cancer agents, cell imaging and in photo-thermal applications, along with many other applications. For our applications, we explored graphene and graphene like nano-dimensioned materials as immobilization matrix for detection of anemia biomarkers, and cardiac biomarkers. These materials not only provide matrix but also facilitate fast reactions due their catalytic property which ultimately helps in signal amplification.

- Title:Modelling and Simulation of Cathode Material for 2D Lithium-ion Solid-State Battery
- Time :
This work has been presented to develop a simulation model of 2D Lithium-ion Solid State Battery (SSB) for studying the thermal and electrical characteristics by varying the thickness of the electrode. This simulation model helps us to explore the cathode material characteristics to optimize lithium-ion SSB’s performance. In this paper, the simulation model has been formulated with 2D domain geometry and also encapsulated with variable parameters on a Multiphysics software. The electrochemical model was also formed with the help of mathematical modeling equations to obtain the rate capability of the li-ion SSB. This simulation model study shows the good thermal stability of the cathode material with a varied temperature range from 0⸰C to 150⸰C. Moreover, the electrical and electrochemical results also show good electrochemical reactivity, proper diffusion of li-ions, and good transport properties in the positive electrode of the li-ion SSB. Furthermore, this simulation approach shows a proper discharge curve at various C-rates and also highlights the concentration of li-ion, electrons, and heat flux with good stability in the Lithium-ion SSB.
