2:00 p.m. - 3:00 p.m. @ Young Hall 302Speaker: Amanda Morris From: Virginia Tech Title: Exploring Organic Frameworks for Use as Integrated Artificial Photosynthetic Assemblies Abstract: The finite supply of fossil fuels and the possible environmental impact of such energy sources has garnered the scientific community’s attention for the development of alternative, overall carbon-neutral fuel sources. The sun provides enough energy every hour and a half to power human civilization for an entire year. However, two of the remaining challenges that limit the utilization of solar energy are the development of cheap and efficient solar harvesting materials and advances in energy storage technology to overcome the intermittent nature of the sun. In the seminar, the research projects to be discussed focus on the development of an integrated artificial photosynthetic array for solar energy storage. Photosynthetic systems consist of light harvesting arrays and redox mediators that can funnel the electrochemical potential stored in a molecular excited states to catalytic centers to drive the oxidation of water and the reduction of CO2 to sugars. Many artificial approaches to this chemistry have been reported. In the Morris group, we investigate porous coordination networks (PCNs) as both light harvesters and high surface area catalysts as photosynthetic mimics. PCNs combine the synthetic diversity possible with molecular catalysts and the ease of recovery of heterogeneous catalysis. Theoretically, the high surface area of PCNs can be exploited to produce a higher catalytic rate per geometric area than those realized by other approaches. Additionally, the incorporation of molecular chromophores into networks has been show to lead to enhanced luminescence quenching. Our studies span the scope of artificial photosynthetic chemistry and include mechanistic investigations of homo-resonance energy transfer, electron transport, and catalysis within PCNs.

7:00 p.m. - 8:15 p.m. @ Center for the Sciences M070Humankind has always strived to unlock the celestial secrets of our closest planetary neighbor. We have come a long way since early astronomers gazed through simple telescopes and theorized about massive canals on the Red Planet. Orbital satellites have begun to map its surface in detail and nuclear-powered rovers are working to unlock the chemical and geologic secrets. Celebrate National Chemistry Week by gathering a group for a mission to explore the chemistry of Mars! Join us live as our panel of experts shares what we know about the planet and the steps that need to be taken to safely send men and women to walk on its surface. Discover the challenges of long-term space travel and the materials, biochemistry, and astrochemistry that will help make this mission possible.
