"Progress Towards Remote Activation of Enzymes"

Thursday March 2nd, 2017 at 4:00 PM in Chemistry A101

Research Seminar The emerging field of remote enzyme activation, or the ability to remotely turn thermophilic enzyme function on or off, could be a valuable tool for understanding cellular processes. But with only a few preliminary reports1,2, little about the concept is understood. Through exploitation of the temperature dependence of enzymatic processes and high thermal […]

"Unraveling Complex Aggregate Behavior: Perylene Diimides, A Case Study"

Thursday March 9th, 2017 at 4:00 PM in Chemistry A101

Research Seminar 2-dimensional infrared spectroscopy (2DIR) probes molecular vibrations in solution, and thus, is useful for its structural sensitivity to molecular as well as aggregate structures. However, molecular orientation, the nature of coupling, solvation, and many degrees of freedom contribute to the resulting 2DIR spectrum. The relative orientations of molecules in an aggregate effect the […]

"Ultrafast vibrational spectroscopy of ionic liquids: Insight into carbon capture, chemical reactions, and energy storage"

Thursday March 23rd, 2017 at 4:00 PM in Chemistry A101

Ionic liquids are complex solvents. Due to their unique properties they are being explored for applications as carbon capture absorbents, electrolytes, and energy storage media. From a fundamental perspective, ionic liquids are at the forefront of research because of their structural and dynamical heterogeneity. Many important physical and chemical properties are dictated by the solvation […]

"Using TDDFT for Selective Tuning of 1st Row Transition Metal Complexes for Inner Sphere Photocatalysis"

Thursday March 30th, 2017 at 4:00 PM in Chemistry A101

Research Seminar abstract Transition metals make for ideal photocatalysts due to their absorption of visible light. Current research relies heavily on ruthenium and iridium based catalysts.1 Unfortunately, due to their rarity, these metals are not sustainable. Earth abundant 1st row transition metals provide an interesting alternative to rarer metals, but moving up the periodic table […]

"Allosteric Pathways of the Dengue NS3 Helicase Enzyme During the NTP Hydrolysis Cycle"

Thursday April 13th, 2017 at 4:00 PM in Chemistry A101

Research Seminar Abstract The Flaviviridae non-structural 3 (NS3) protein is a viral helicase that plays a pivotal role during the replication of the viral genome. Specifically, this enzyme uses energy released during the hydrolysis of nucleotide triphosphates (NTPs, e.g. adenosine triphosphate, ATP) to translocate and cause the unwinding of a double stranded RNA substrate, thereby […]

Ignacio Franco Presents:

"Toward atomistic modeling of single-molecule electromechanical spectroscopies"

Thursday April 20th, 2017 at 4:00 PM in A101 Chemistry

In this talk, I will present theoretical and computational advances by my group toward the atomistic modelling of molecular electronics experiments that simultaneously measure the electric and mechanical properties of single-molecules.  Such class of measurements have the potential to develop into a highly discriminating multidimensional spectroscopy that can be used to interrogate Chemistry and Physics […]

"Towards Understanding the Atomistic Disorder of Synthetic Bone Mineral"

Thursday May 4th, 2017 at 4:00 PM in Chemistry A101

Research Seminar abstract Natural bone mineral most closely resembles the mineral calcium hydroxyapatite.  The compositional and structural disorder of the highly substitutable apatite has resulted in a poor atomistic understanding of the mineral phase of bone.  Although many studies using X-ray1 or neutron2,3 diffraction and computational1,4 experiments have attempted to understand the atomistic structure of […]


"Toward a general scheme to predict ionic liquid effects on biological molecules"

Thursday June 1st, 2017 at 4:00 PM in Chemistry A101

Ionic liquids (ILs) have received significant attention in the past few decades as a novel class of materials with numerous proposed technological applications. ILs are salts that are liquid at the operating temperature; for room temperature operation this typically entails a large organic cation and a smaller anion. At the crux of their interesting behavior […]
