Aerosol-OT (AOT) reverse micelles are a well-known, self-assembled model system for studying water in nanoconfinement. Although all-atom molecular dynamics (MD) simulations universally find AOT reverse micelles to be non-spherical, most theories about the reverse micelles still assume a spherical shape for simplicity, such as the core/shell hypothesis. This simplification ignores any interactions between the shape […]

Styrenes are widely utilized synthetic precursors for a range of polymerization and hydro-/dual-functionalization reactions. Chemists commonly probe the mechanism of these reactions by selectively incorporating deuterium onto the vinyl positions of the styrene derivative. There have been several catalytic methods reported to either completely label the vinyl group or selectively label the β-position with deuterium. […]

Literature Seminar Abstract Self-assembly has occurred in nature since the beginning of time, but only in the past 30 years has the term found its way into chemical literature to describe autonomous organization in various systems, from monolayers to nanoparticle superstructures. Nanoparticle self-assembly can be used as a high throughput method for the fabrication of […]

About the Seminar The interface between two fluids is not only important for defining reactivity of dislike materials, but is also applicable for the preparation of stable higher order structures. Recently, the Pentzer lab developed 2D carbon-based nanosheets that assemble at different fluid-fluid interfaces including oil-water, oil-oil, and ionic liquid-water and demonstrated the use of […]

In this seminar, I will discuss two developments in ultrafast nonlinear IR spectroscopy for exotic molecular materials: (1) 2D IR spectroscopy for molecular vibrational polaritons and (2) transient electric field induced VSFG spectroscopy for probing interfacial charge transfer. Both show the advantages of ultrafast nonlinear IR spectroscopic technique: to decipher hidden physics of exotic molecular […]

Literature Seminar Abstract Petroleum production is a multibillion dollar global industry producing over nine million barrels of oil a day.  All unrefined petroleum contains sulfur which when combusted forms acid rain and smog producing SOx.  Complete sulfur removal during refining is challenging due to refractory molecular structures and difficulties in their characterization.  Characterization would allow […]

Literature Seminar Abstract Insecticides are ubiquitous and trace levels can be found in soil, water, air, and food residues. The mode of action that causes the insecticide to be harmful to insects is also found in humans, so if humans are exposed to high enough levels, there are negative health effects. Therefore, it is necessary […]

Literature Seminar Abstract: Metalloenzymes drive chemical processes across life forms and mimicking this reactivity still remains a synthetic challenge. Almost all metalloenzyme active sites are composed of transition metals. In 2007 in volcanic mudpools in southern Italy, the bacteria Methylacidiphilum fumariolicum was discovered with an enzyme containing a lanthanide active site in a methanol dehydrogenase […]

Literature Seminar Abstract Semiconductor nanoparticles (NPs) are used for a wide variety of applications, including sensing, photocatalysis, and optoelectronics. To optimize their utility for these applications, charge carriers must be able to flow efficiently through the material. However, semiconductor NPs exhibit inherent structural and electronic defects that can trap charge carriers and prevent them from […]

The current practices in the generation and disposal of synthetic polymers are largely unsustainable. Several solutions have been intensively pursued to address this global challenge but the current solutions suffer from either significant materials value and quality losses or unintended environmental consequences. To address this challenge, we have designed and synthesized next-generation sustainable polymers that […]

Directly observing electron dynamics at surfaces is required to reveal the material properties that determine efficiency during energy conversion catalysis.  Toward this goal, we have developed a tabletop instrument for femtosecond X-ray spectroscopy of surfaces.  This method combines the benefits of X-ray absorption, such as element, oxidation, and spin state specificity, with surface sensitivity and […]

4th Year Research Seminar: Ambient particulate matter (PM) air pollution is associated with negative health effects, including respiratory and cardiovascular diseases, and is estimated to cause millions of deaths worldwide each year.1 The current hypothesis is that PM produces reactive oxygen species (ROS) in the body, which leads to oxidative stress.2 Dithiothreitol (DTT) is commonly […]

We and others have demonstrated the use of triaminotriazine (melamine) as a synthetic base-triple motif in a family of molecules we call bifacial peptide nucleic acid (bPNA). Bifacial PNA engages two oligo T/U strands simultaneously to form a unique triple stranded structure. bPNAs can serve as allosteric triggers of aptamer protein-binding, ribozyme catalysis, aptamer small-molecule […]

ABSTRACT  The ubiquitin conjugating enzyme, Ubc13, catalyzes lysine ubiquitination, a type of protein post-translation modification. Ubiquitinating a protein can signal for its degradation and affect its activity. Ubiquitination also plays a role in DNA repair and inflammatory response. Defects in this process are linked to different disorders including cancer, Parkinson’s and Alzheimer’s diseases. The accepted […]

Room temperature ionic liquids (RTILs) have been a major focal point in many areas of chemistry and engineering due to their favorable properties and emerging capabilities. RTILs are popular as solvents for green chemistry due to their near-zero vapor pressure and negligible flammability. Their high ionic conductivity, stability, and selectivity for certain light gases make […]

Accurate predication of both climate and air quality under a changing earth system requires a full understanding of the sources, feedbacks, and ultimate fate of all atmospherically relevant chemical species. Volatile organic compounds (VOCs) make up a large portion of the reactive chemical species in the atmosphere and are key components in air quality and […]

Photoredox catalysis has gained recent prominence due to the ability to employ mild reaction conditions and achieve challenging chemical transformations. A significant portion of this work has focused mainly on employing ruthenium andiridium polypyridyl complexes due to their characteristics as photocatalysts. However, as photocatalysis becomes morecommonplace in synthetic labs, so does the need for a […]

Organocatalyzed atom transfer radical polymerization (O-ATRP) has become a powerful methodology for the synthesis of well-defined polymers in a highly efficient manner. This process is made possible due to the advent of highly reducing organic photoredox catalysts (PCs) which are driven by visible light. The family of N,N-diaryl dihydrophenazine PCs have been shown to polymerize […]

Organic acids are numerous and pervasive in Earth’s lower atmosphere. They contribute to ozone formation chemistry as well as the production of secondary organic aerosols, thus impacting both human and ecosystem health. Despite their relevance, organic acid budgets in the atmosphere remain poorly understood. Models underestimate measured ambient concentrations of many organic acids, suggesting an […]
