Excited-state molecular structures and dynamics, i.e. the rearrangement of the nuclear geometry and electron density distributions upon electronic excitation, is the foundation of many photoinduced …
Safe storage and disposal of spent fuel rods from nuclear power plants calls for the ability to model actinide complexes and compounds in the environment. …
The brain's neurotransmitter system is of vital importance to the proper functioning of the brain. In particular, neurotransmitter dopamine has drawn considerable research interest in …
Structural rearrangements within single molecules occur on ultrafast time scales. Many aspects of molecular dynamics, such as the energy flow through excited states, have been …
Our central goal in this thesis is to investigate the vibrational energy relaxation (VER) of perylene in solution. The size of a perylene molecule makes …
The photoacoustic effect, also frequently called the optoacoustic effect, was discovered by Alexander G. Bell in 1880. The effect refers to the generation of acoustic …
My dissertation works focus on supramolecular patterning of physisorbed self-assembled monolayers. The goal is to develop reliable molecular recognition strategies that direct sets of molecules …
Controlled synthesis of nanoparticles (NPs) is the key to developing highly efficient and stable catalysts for various reactions, including those involved in energy conversion systems, …
Monodisperse FePt NPs are synthetically controlled from chemically disordered face centered cubic (fcc) structure to ordered face centered tetragonal (fct) structure. The NP’s electrocatalytic efficiency …
In the past two decades, the synthesis of magnetic nanoparticles (NPs) has been intensively explored for both fundamental scientific research and industrial applications. Different from …
Highly-efficient heterogeneous catalysts are essential for the development of a vast number of renewable energy technologies, such as fuel cells, metal–air batteries and water splitting. …
Charge transfer (CT) is one of the most important and most general reactions that exist in living cells, solar energy conversion devices, chemical synthesis and …
The study of ultrafast chemical dynamics aims to elucidate the “how” and “why” of chemistry by measuring molecular structures as they evolve on their native …
Cyclic organic molecules play significant roles in many fields of chemistry. The substituted heterocycles are found in natural products, pharmaceutical compounds and polymeric systems. Other …
Understanding of structural, reaction and charge transfer dynamics of any molecular system has been a challenge for both modern spectroscopists and theorists. The structural changes …
