Functional Nanomaterials & Electrochemical Devices (FNMED)
Overview
Welcome to the Functional nanomaterials and Electrochemical Devices (FNMED) laboratory led by Dr. R.B. Rakhi and affiliated to the Centre for Sustainable Energy Technologies (CSET) of CSIR-National Institute for Interdisciplinary Science and Technology.
In the NFMED lab, we synthesize nanostructured electrode materials for electrochemical energy storage, electrocatalysis, and electrochemical sensing applications. Currently, the group focuses on the growth of 2D layered materials (graphene, MoS2, MXenes, and heterostructures), transition metal oxides, and organic/inorganic hybrid composites.
We look forward to both internal and international collaboration as well as comments, suggestions, and guidance from colleagues and peers with shared research interest.
