Is Carbon Capture Realistic?

Christopher Wilmer

Assistant Professor,
Chemical and Petroleum Engineering Department,
University of Pittsburgh

Join University of Pittsburgh professor Chris Wilmer for a discussion of the future of carbon capture technology. This very active area of engineering research explores the development of technologies that can be retrofitted onto fossil fuel-based power plants to reduce greenhouse gas emissions into the atmosphere. Retrofitting thousands of coal power plants across the globe would be a massive undertaking, and researchers need to know how feasible such a project would be.

In his talk, Wilmer will consider this problem from the molecular scale and ask what the most efficient carbon capture membrane would look like, whether it can realistically help mitigate global warming, and how it compares to existing technologies.

Wilmer is an assistant professor in the Chemical and Petroleum Engineering Department at the University of Pittsburgh. His research focuses on the use of large-scale molecular simulations to help find promising materials for energy and environmental applications.

Old Drugs, New Tricks: Putting an End to Traditional Eye Drops

Old Drugs, New Tricks: Putting an End to Traditional Eye Drops

Presenter:

Morgan Fedorchak

Director 
Ophthalmic Biomaterials Laboratory

 

Glaucoma is the second leading cause of blindness worldwide, expected to affect up to 3 million Americans by 2020. One of the main risk factors in glaucoma is an unsafe increase in intraocular pressure (IOP).  IOP reduction in patients with glaucoma is typically accomplished through the administration of medicated eye drops several times daily, the difficult and frequent nature of which contributes to patient adherence rates estimated to be as low as 30%.  Newer drug delivery methods for glaucoma aimed at improving patient adherence require clinician administration of invasive injections or implants. This talk will encompass the rational design and testing of a variety of controlled release systems for delivery of ocular drugs as well as the many significant considerations for translating these technologies to the clinic where they may benefit patients. In particular, discussion will focus on our team’s development of a completely unique formulation that provides one month of therapeutic levels of glaucoma medication from a noninvasive eye drop. We believe that this new treatment method may have the ability to overcome the issues inherent to traditional eye drop medication while avoiding the need for more invasive techniques.

 

Morgan Fedorchak is an Assistant Professor of Ophthalmology, Chemical Engineering, and Clinical and Translational Science at the University of Pittsburgh and the director of the Ophthalmic Biomaterials Laboratory. She attended Carnegie Mellon University where she obtained her B.S. in both Chemical Engineering and Biomedical Engineering in 2006. She later earned her PhD in bioengineering at the University of Pittsburgh in 2011 under Dr. William Federspiel studying hemofiltration and medical devices. Subsequently, she was awarded a fellowship from the Fox Center for Vision Restoration to participate in a collaboration between Dr. Steve Little and Dr. Joel Schuman as a postdoctoral researcher in March of 2011. This work formed the basis for the development of a patent pending drug delivery system for glaucoma that was recently featured in The Wall Street Journal. Her research is currently supported by the National Eye Institute, the Cystinosis Research Foundation, the University of Pittsburgh Center for Medical Innovation, and the Wallace H. Coulter Foundation.

Spiders: Myths and Facts

 Follow along with the slideshow here.

What’s it like to live in a spider society? Join University of California Santa Barbara Assistant Professor Jonathan Pruitt as he discusses "Spiders: Myths and Facts."

Sociality is rare in spiders. Pruitt’s research concerns one species of spider that lives in social groups and how social interactions between the arachnids impacts their behavior and environment.

Pruitt’s research explores the ecological consequences of individual variation in behavior for individuals, populations, and communities. Is aggressive behavior rewarded? What mix of docile and aggressive individuals is optimal for a community?

Pruitt’s research considers the role of individual differences in patterns of task allocation within societies, and how these patterns impact the long-term performance of groups in different environments. In non-social systems, Pruitt looks at how variation in behavior impacts species interactions across different ecological niches, in both terrestrial and marine systems.

Pruitt performed his graduate studies at the University of Tennessee, Knoxville. He then conducted postdoctoral studies at the University of California, Davis. He is currently an assistant professor in the Department of Ecology, Evolution and Marine Biology at the University of California Santa Barbara.

If You Can’t See It, It Doesn’t Exist: Connections of Air and Climate Pollution with Policy Decisions

February 2, 2016

Neil Donahue

Professor of Chemistry & Chemical Engineering

Director Center for Atmospheric Particle Studies at Carnegie Mellon University

 

If  You Can’t See It, It Doesn’t Exist: Connections of Air and Climate Pollution with Policy Decisions

 

The effects of climate change, air pollution, and efforts by leaders to address these effects are pressing issues that pervade recent news-cycles – from climate talks in Paris to the increase in “red alert” days in Beijing. Dr. Neil Donahue will discuss “If  You Can’t See It, It Doesn’t Exist: Connections of Air and Climate Pollution with Policy Decisions.”

Donahue is a Professor of Chemistry & Chemical Engineering at Carnegie Mellon University; and a Science & Engineering Ambassador with the National Academy of Sciences and National Academy of Engineering. He directs the Steinbrenner Institute for Environmental Education and Research.

Climate pollution is mostly invisible and diffuse. More traditional air pollution — haze and smog — is visible and localized.  However, both cause a world of hurt, and addressing them together may be a key to making progress on both.  The “social costs” of pollution can be very high, with the costs of climate pollution distributed over the globe and over generations, while the social costs of air pollution bourn locally and immediately, including contribution to millions of deaths every year.

Donahue will discuss the role of three current research activities towards enabling decision-makers to consider the costs and benefits of policies that could affect both pollution types.  The research includes fundamental experiments about fine atmospheric particles at CERN, the particle-physics research institute in Geneva; a collaboration to model the life-cycle of carbon in regional pollution in China; and development of a decision support tool for city policy makers to compare policy “intervention” options in terms of costs and effectiveness for climate and air-pollution benefits.

Donahue seeks to understand how Earth's atmosphere works and how humans affect the atmosphere. He strives to help all graduating CMU students understand the climate problem and to apply their outstanding problem-solving skills to solutions of this enormous challenge.

Donahue’s research focuses on the behavior of organic compounds in Earth's atmosphere. The world experts in his research group study what happens to compounds from both natural sources and human activity when they are emitted into the atmosphere. Recently, the group’s research has focused on the origin and transformations of very small organic particles, which play a critical role in climate change and human health. Particles scatter light, influence clouds, and kill roughly 50,000 people each year in the U.S., mostly of heart attacks.

Donahue earned a degree in physics from Brown University and a doctorate in meteorology from MIT. He spent nine years as a research scientist at Harvard before returning to Pittsburgh in 2000.
