  From Photoreceptors to Photoelectrodes: Integrating Biological Light-Harvesting Mechanisms with Nanostructured Photoelectrochemical Systems

  By R. Ranjitham, A. Ajitha, K. Seethalakshmi, S. Ravichandran

  Abstract: The efficient conversion of solar energy into electrical and chemical energy is a major scientific challenge of the twenty-first century. Natural photoreceptors provide valuable models for addressing this challenge because they have evolved highly efficient mechanisms for capturing and converting light energy. Biological systems such as rhodopsins, bacteriorhodopsins, proteorhodopsins, cryptochromes, phototropins, and phytochromes employ chromophore-driven photoinduced electron and proton transfer processes to initiate a wide range of physiological responses, including …

  Multiscale Catalytic Strategies for Sustainable Chemical Production: Integrating Computational Catalysis, Process Technology and Biocatalytic Transformations

  By R. Ranjitham, A. Ajitha, S. Ravichandran

  Abstract: The transition toward sustainable chemical manufacturing requires catalytic technologies capable of maximizing resource efficiency, minimizing greenhouse gas emissions, and enabling the utilization of renewable feedstocks. Recent advances in computational catalysis, process technology, and biocatalytic transformations have created opportunities for the development of integrated catalytic platforms spanning molecular, reactor, and process scales. Density functional theory (DFT), machine learning-assisted catalyst discovery, and multiscale modeling have accelerated the rational design of heterogeneous, homogeneous, …
