Research Theme

Sustainability of synthetic materials is the primary challenge towards realizing practical applications. While designing a functional material, molecular structures and mesoscopic assembly process, both play imperative roles to make it sustainable. We aim to programme the molecular assembly in mesoscale to realize sustainability for targeted applications, including filtration, photocatalysis and smart optical materials.

Publication update: Our first paper is accepted in Mol. Syst. Des. Eng. (emerging investigator series) In the context of chemical separation, membrane based technologies are the most advanced and sustainable. One of the fundamental aspect of membrane based separation is molecular diffusivity. In this work we have demonstrated that molecular diffusivity in a porous thin film (which can act as a membrane) can be enhanced by atleast a factor of 2, if the nanochannles are aligned in a preferential way.

Molecular diffusion follows concentration gradient path. We have discovered that in a porous material, metal-organic framework, molecules can move orthogonal to the gradient. To know more: https://www.nature.com/articles/s41467-023-37739-8
