Magnetic field effects on radical pair reactions – from bird navigation to chemical compasses and novel spectroscopic tools Weak magnetic fields (< 30 mT) can have a profound influence on radical pair reactions. This is, at first sight, puzzling since the magnetic interactions are typically much smaller than the thermal energy at room temperature. The radical pair is created in a highly non-equilibrium state, however, displaying significant mixing between its singlet and triplet spin states. The mixing rate is altered if a magnetic field is present via the Zeeman interaction.

Will the Real Finite-Temperature Perturbation Theory Please Stand Up? Chemical applications of statistical mechanics typically assume that the electronic partition function is trivial, as all members of the system are in the ground electronic state. When this approximation breaks down (example: electrical conductors), it is necessary to combine statistical mechanics and electronic structure theory to determine the electronic partition function. This composite theory is called a "finite-temperature" theory. The oldest finite-temperature theory is finite-temperature perturbation theory (FTPT). In 2013, Prof. Type of Event: Physical Seminar Read more about Will the Real Finite-Temperature Perturbation Theory Please Stand Up?

Cis/trans Photoisomerization: From Photoswitches to Light-Activated Molecular Rotary Motors Over the past few decades synthetic chemists were striving to make a leap from simple molecular switches to molecular systems with controlled dynamic behavior. These research efforts were inspired by directional motion in living systems that are key to almost every essential process in the cell. The structure of molecular rotary motors resembles the layout of macroscopic electric motors which are widely used to convert energy into motion. However, controlling the dynamic behavior at the molecular level is challenging.

Applying X-Ray crystallography for elucidating enantioselective alcohol dehydrogenase/carbonyl reductase enzyme – substrate interactions The use of microorganisms in fermentation for ethanol production or in bio-catalysis for drug synthesis has been attracting attention of scientist over the past few decades because it efficient, cost-effective, and environment-friendly. The aim of my research project is applying X-Ray crystallography to investigate the enzyme structures of enantioselective Alcohol dehydrogenase (ADH) and Carbonyl reductase (CAR) from these organisms to elucidate the interaction with the substrate at the active site and reaction mechanism.

Laboratory Astrochemistry Studies along the Cosmic Cycle of Gas Tracing the evolution of baryonic matter from atoms in space to stars and planets hinges on an accurate understanding of the underlying chemical processes controlling the properties of the gas at every step along this pathway. Here I will explain some of the key epochs in this cosmic cycle and highlight our laboratory studies into the underlying chemistry that controls the observed properties of the cosmos.
