In situ transient absorption spectroscopy during materials formation
When
-
Abstract: Molecules, polymers, and nanocrystals can form the active layer in electronic devices such as photovoltaics and light-emitting diodes. Their electronic structure and excited state dynamics dictate their function and suitability for these applications. Transient absorption (TA) spectroscopy is used to measure these properties, and has provided remarkable insights into the behavior and function of electronic materials.
Chemistry in multiple phases and at interfaces in the contemporary and ancient Earth’s atmosphere.
When
-
Abstract: Inspired by atmospheric measurements, which have established that atmospheric chemistry occurs in many phases and at interfaces, my group explored the unique reaction environments presented by planetary atmospheres. In this presentation, the special morphological and chemical properties of organic films on aqueous solutions will be discussed with reference to atmospheric aerosols, sea surface microlayers, cloud and fog droplets.
In Search of Hidden Conformational States of RNA
When
-
Abstract: RNAs are notoriously flexible biomolecules, requiring an ensemble-representation of their structure. Constructing such dynamical ensembles, which comprise the set of conformations an RNA can adopt, along with their associated populations, is challenging because biophysical measurements only indirectly report on the properties of the underlying conformational (Boltzmann) distribution.
Exploring the Extremes of Excitonic Photophysics
When
-
Abstract:My group studies the extremes of excitonic absorption and emission in condensed phase chemical/semiconductor systems. We have two primary themes: 1) The use of self-organized nanoscale systems that have controlled light absorption and energy propagation; 2) Development of molecular/inorganic materials which absorb and emit from 1-2 microns, the Short-Wavelength Infrared (SWIR). In this talk, I will discuss some of our recent research projects in the group.
The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
