Annalise Maughan Presents:
"Towards a Paradigm of Materials by Design: The Crystal Chemistry of Perovskite Halide Semiconductors"
Friday January 27th, 2017 at 4:00 PM in Chemistry A101
Research seminar In less than a decade of dedicated research, perovskite halide semiconductors such as methylammonium lead iodide (CH3NH3PbI3) have achieved photovoltaic power conversion efficiencies rivaling those of conventional compound semiconductors, and present exciting opportunities for fundamental and application-based materials research. In the wake of rapid growth and development of yet-higher-efficiency devices, the fundamental chemical […]

"Metal–Organic Framework-based Materials for Localized Generation of Nitric Oxide at Biointerfaces"
Friday February 17th, 2017 at 4:00 PM in Chemistry A101
Research seminar Nitric oxide (NO) is an endogenously produced molecule that has been demonstrated to aid in the prevention of thrombus formation and promote accelerated wound healing.1,2 Metal–organic frameworks (MOFs) are a class of crystalline materials that consist of organic ligands coordinated to metal centers. Certain copper-based MOFs have demonstrated the ability to enhance the […]

Hach Distinguished Speaker. Department Colloquium.
Sarah Tolbert Presents:
"Solution Processed Nanomaterials for Energy and Next Generation Devices"
Friday March 3rd, 2017 at 4:00 PM in Chemistry A101
Department Colloquium In this talk, we examine ways that solution processed nanostructured materials can be used to address both fundamental and practical issues relevant to next generation technology. We begin with nanoporous materials for electrochemical energy storage. Materials with appropriate porous architectures can be synthesized using either block-copolymer templating methods or using selective solution phase […]
Scott Folkman Presents:
"Electrocatalytic Water Oxidation Catalysis Beginning with Cobalt Polyoxometalates: Searching for the True Catalyst"
Friday March 10th, 2017 at 4:00 PM in Chemistry A101
Research seminar Renewable Hydrogen is an attractive alternative to replace carbon based fuels. Efficiently generating H2 in a carbon neutral process requires electrochemical splitting of water into its H2 and O2 components, thereby storing 285.5 kJ/mol of H2 produced. However, the kinetic bottleneck, and therefore efficiency-limiting reaction of H2 generation, is the 4 e–, 4H+ […]
Chase Gerold Presents:
"Observing Dynamic Surface Chemistry and its Relevance to the Oil Recovery Problem"
Friday March 31st, 2017 at 4:00 PM in Chemistry A101
Research seminar abstract Current industrial processes for recovering crude oil from microporous underground reservoirs are inefficient and recover only 30-50% of the oil that was originally contained within the reservoir.1 The oil recovery process is inefficient largely due to unfavorable interactions between surfactant species that are native to the oil phase and the oil reservoir […]
Efrain Rodriguez Presents:
"New Layered Metal Chalcogenides as Functional Materials"
Friday April 14th, 2017 at 4:00 PM in Chemistry A101
Kevin Klunder Presents:
"Buried Treasure: Reappraisal and Repurposing of Ignored High Performance Electrode Materials"
Friday April 21st, 2017 at 4:00 PM in Chemistry A101
Research seminar abstract The physical and molecular structure of the electrode underlies electrochemical charge transfer. Efficient charge transfer (kinetics) is a significant factor governing the performance in nearly all electrochemical systems, including fuel cells, Li-ion or redox flow batteries, chemical sensors, and solar fuels. In the development of new electrode materials there is a constant […]
Jing Tang Presents:
"Organopolymerization of Multifunctional Gamma-Butyrolactones"
Friday April 28th, 2017 at 4:00 PM in Chemistry A101
Research seminar abstract The first successful polymerization of the naturally occurring, tri-functional Tulipalin B , or β-hydroxy-α-methylene-γ-butyrolactone (βHMBL) is established. N-Heterocyclic carbene (NHC) and phosphazene superbase catalysts have been found to effectively polymerize βHMBL into polymer products, despite its trifunctionality consisting of reactive hydroxyl and exo-methylene groups as well as a five-membered lactone ring.. Initial analysis […]
Michelle Mann Presents:
"Plasma Processing of Polymeric Materials to Tune Antibacterial Properties for Environmental & Biomedical Applications"
Friday May 5th, 2017 at 4:00 PM in Chemistry A101
Research seminar abstract Polymeric constructs are widely used in medical and environmental settings, such as scaffolds for wound healing and drug release, membranes for dialysis and water treatment, and tubing for blood transport.1 Polymers are often chosen for their desirable bulk properties, such as porosity, biodegradability, mechanical strength, and architecture; however, most are hydrophobic and […]
