This project aims to build a physical-organic chemistry framework of transferable molecular descriptors for a relatively new but a rapidly developing area of unimolecular electronics (UE) using advanced computational chemistry tools. Established structure-property relationships will drive the cutting-edge applications of UE in sensing and catalysis and significantly expand our understanding of charge transport involving free radicals and non-covalent assemblies. Expected outcomes of this project include new design guidelines and candidate molecular architectures for such practical applications as organocatalysis inside molecular junctions, molecular spintronics and molecular sensors for reactive oxygen species and nitroaromatic pollutants.Read moreRead less

Quantum refinement of DNA X-ray structures. DNA carries the genetic map of life and refinement of its x-ray structures is a key tool to understand its functions. Standard refinement, however, relies strongly on empirical geometry constraints, and it is known that these can induce unphysical features. Quantum mechanical (QM) methods have now evolved to a level that offers an intriguing way out of this dilemma. In this project, state-of-the-art QM methods will be applied to DNA x-ray structures, a ....Quantum refinement of DNA X-ray structures. DNA carries the genetic map of life and refinement of its x-ray structures is a key tool to understand its functions. Standard refinement, however, relies strongly on empirical geometry constraints, and it is known that these can induce unphysical features. Quantum mechanical (QM) methods have now evolved to a level that offers an intriguing way out of this dilemma. In this project, state-of-the-art QM methods will be applied to DNA x-ray structures, and a unique quantum refinement scheme will be developed. Such a scheme will provide crystallographers with a new tool to determine DNA structures with greater accuracy and it will offer benefits to many areas of the life sciences that depend on such accurate structures.Read moreRead less

Enzymes catalyze quite fantastic chemistry under mild physiological conditions. Many special chemical concepts (such as "transition-state stabilization" and "entropy-enthalpy compensation") proposed to explain these powers are unnecessary. Uniquely for a catalyst, these powers are integral to the structure, properties and dynamics of the protein, as constrained and selected by evolution. The question is how do they work? Answering this requires energetic and thermodynamic analysis beyond current experimental techniques, but accessible by computer simulation. We aim to develop a robust toolkit of simulation methods and protocols, blind test them by predicting the mechanism of a new enzyme, with followup experimental validation.

This project aims to address a major challenge in quantum chemistry - how to extend the applicability of high-level quantum chemical methods to larger molecules. High-level quantum chemical methods can consistently obtain reliable thermochemical and kinetic data, but due to their steep computational cost, they are only applicable to relatively small molecules. The project expects to introduce new concepts and methodologies that build on recent breakthrough research in the field of ab initio computational chemistry. The new methods should be capable of energetic predictions of unprecedented accuracy for relatively large systems across the Periodic Table and will be used for the development of better density functional theory procedures.Read moreRead less
