Science Café Program

The LRSM, through the NSF-supported Penn MRSEC, continues a series of Science Cafés that began in 2011 to promote NOVA’s four part TV series on materials, ‘Making Stuff with David Pogue,’ on public television. The Science Cafés, which are science talks for laymen about materials-related topic of current interest, will take place at 7:30 pm at Stoney’s British Pub, 3007 Concord Pike, Wilmington DE and World Cafe Live, 3025 Walnut Street, Philadelphia, PA 19104, at 6:00 pm.

These programs are free and anyone who is interested is invited to attend. No purchase is necessary.

Preston B. Moore / Smart Materials That Respond to Stimuli Preston B. Moore
Chemistry Department, University of the Sciences, Philadelphia
Smart Materials That Respond to Stimuli
 

Materials that change in response to stimuli are very desirable for a range of applications from biometrics to energy storage. Recently, a facile synthetic route to binary polymer brushes and mosaic polymer brushes, which are novel and unique organizations of polymers at solid substrates, has been reported. Mosaic brushes are homogeneously distributed islands of densely grafted polymers, whereas the binary brushes are two immiscible polymers grafted to the surface. Both are smart materials that feature well-developed interfaces and stimuli-responsive behavior. The talk will discuss the synthesis and simulations of these novel materials, and their potential applications.

The Importance of Batteries and Super Capacitors to the Electric Car and to an Efficient Power Grid
 

Some important aspects of modern technology such as transportation and the efficiency of the power grid are strongly tied to new advances in charge storage technology. Most electric car manufacturers are attempting to obtain a range comparable to internal combustion driven cars, about 500 miles, and all are seeking the right battery / super capacitor for the task. Of course, load leveling, avoiding the cyclical increase in grid load due to seasons, and day / night load fluctuations are a most important concern. We will discuss batteries, energy and power densities and the two types of super capacitors used, electrical double layer and Faradaic.

David R. Busch / From Flashlights to Brain Monitors, Diffuse Optics in Tissue David R. Busch

From Flashlights to Brain Monitors, Diffuse Optics in Tissue
 

When you cover a flashlight with your hand, why does it glow red? Tissue absorbs blue and green light, but red light passes through. Despite the red light, you can’t see bones. This talk will describe the whys behind these common observations and explain how optics can be used to measure and monitor the brain, without using ionizing radiation.
