Lighting up the charged brigade: laser spectroscopy of protonated and metal-containing complexes. Increasingly, the design of new pharmaceuticals uses computer modeling to account for the shapes of molecules and how they interact with their surroundings. The strongest forces between molecular components are those that involve charged chemical species known as ions.

Increasingly, the design of new pharmaceuticals uses computer modeling to account for the shapes of molecules and how they interact with their surroundings. The strongest forces between molecular components are those that involve charged chemical species known as ions. In this project, we will develop advanced laser-based techniques to study in unprecedented detail how molecules respond to the presence of nearby charge, or to acquiring charge themselves. Understanding the nature of these attractions, and the structural changes that they induce eventually results in more accurate computer models. This has relevance to fields that include the architecture of proteins, recognition of signaling molecules in the brain, and drug development.Read moreRead less

Shape-Shifting Molecules: Photoisomerization Action Spectroscopy. This project aims to examine molecules that change shape in response to light in order to gain insight into the biological processes they control. Many biological systems, including the human visual apparatus and bacterial photosynthesis, depend on molecules that change shape in response to light. The project plans to probe shape-shifting molecules with laser light while they are propelled through gas by an electric field.

This project aims to examine molecules that change shape in response to light in order to gain insight into the biological processes they control. Many biological systems, including the human visual apparatus and bacterial photosynthesis, depend on molecules that change shape in response to light. The project plans to probe shape-shifting molecules with laser light while they are propelled through gas by an electric field. Light-induced changes in molecular shape produce detectable variations in drift speed. The ensuing knowledge would help calibrate computational approaches for predicting molecular function. It would also establish foundations for understanding essential biological molecules, including retinals, carotenes and peptides, and for developing new light-activated molecular motors and switches.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

Despite significant advances over the past few decades, many free radical reactions are still carried out in organic solvents that are often toxic, flammable, difficult to recycle and employ undesirable reagents. It is timely that new free radical chemistry be developed that moves away from this "conventional" landscape. This proposal will develop a fundamental understanding of how free radicals interact with, and react in, (unconventional) ionic liquid solvents. This understanding will lead, in turn, to the development of new, more efficient, free radicals methods for the preparation of important materials that include biomolecules. Reduced environmental impact of free radical chemistry is the ultimate aim of this work.Read moreRead less
