Computational Research
At NEMO Lab we have bunch of theoreticians who use Density Functional Theory (DFT) techniques to investigate the materials properties. DFT provides us a tool using first principles to understand the materials world around us. We mainly work on the applications DFT in various areas such as understanding nanomaterials especially 2D materials, energy storage, water remediation and study of biomolecules. .
Theoratical Analysis
We focuse on carrying out theoretical research on bonding, electronic structure, shape and symmetry of molecules and solids as well as on their relationships to chemical and physical properties.!
Computational Facilities
The group houses its own linux based computational facility running on 16, 24 core AMD processors. Various DFT packages used in the group include VASP, Quantum Espresso, Phonopy and JDFTx. .
Two-Photon Lithography
At NEMO Lab, we are equipped with the state of the art Two-photon laser lithography setup which has been conceptualized, designed, assembled and automated in-house. The system is highly modular and among the best available globally.
Detailed Setup
It can be used to fabricate micro/nanostructures by tuning laser wavelength from ~233 nm to ~1100 nm with a hardware precision of 2nm along the x-,y- and z- axis. Structures as large as 25mm x 25mm x 300um can be fabricated with precision using this setup.
Research Advancements
It forms the workhorse for fabrication of 2D and 3D nano/micro structures with subwavelength resolution. The best feature size which has been achieved using this laser is ~50nm using 800nm wavelength. This forms our core strength and provides us the advantage for pursuing research areas like Metamaterials, Plasmonics, Photovoltaics & Stem-cell growth etc.
Energy Generation & Storage
Energy generation & storage forms one of the grand challenges of the present and future generations to come. At NEMO lab we not only focus on energy generation using solar cells but also energy storage using supercapacitors.
Innovative Approach
For Energy generation we not only investigate the materials aspect of photovoltaic devices namely solar cells, We are also pursuing plasmonic metamaterial approach, leading to extraordinary tranmission of light for enhancing the performance of such photovoltaic devices.!
Energy Storage
We have recently developed the concept of coronal nanohybrids of graphene - LDH. These nanohybrids significantly enhance the surface area and hence the specific capacitance. Currently we are working on wide range of materials such as V2O5, MOS2, graphene, polymer composites, Ni-, Mn- and other LDH materials for supercapacitor applications. .
Nano Materials
The discovery of graphene has lead to extensive exploration of two dimensional flatlands resulting in discovery of both elemental and compound 2D materials. Some examples of two dimensional materials being synthesized in the lab are graphene, stanene, monolayers of transition metal chalcogenides, MXene and phosphorene.
Synthesis Materials
We are also engaged in synthesizing different nanostructures of various materials such as Silver, ZnO, PbS, TiO2, Fe2O3, V2O5 and polymers to name a few.
Synthesis Approach
We use both top-down and bottom-up approaches for synthesis of nanomaterials. Some of the techniques used for synthesis of nanmaterials at NEMO lab include traditional wet chemical synthesis methods, microwave synthesis, sol-gel, hydrothermal synthesis, electrochemical etching and laser ablation/deposition based synthesis techniques to name a few
