Description:

The QCC Student Affiliates of the American Chemical Society & The Chemistry Club Proudly Sponsors The Long Island Subsection of the NY-ACS Semimar of Dr. Kamil Woronowicz, Department of Chemistry, United States Military Academy West Point, West Point, New York 10996 - Title of Talk: "Photosynthetic Reaction Centers on Graphene Composite Electrodes for Photocurrent Generation and Energy Storage". Synopsis: Photosynthetic reaction centers convert light energy into charge separation with high quantum yield. Photosynthetic membrane vesicles containing reaction centers have been shown to generate photovoltaic current both on gold and dye-sensitized solar cells, also known as, Gratzel Cells. However, the current density in those approaches remained significantly lower than most modern phtovoltaic cells utilizing organic dye sensitizers. This work is aimed at improving previous designs by utilizing purified reaction centers and interfacing them with graphene oxide electrode. Two immobilization schemes are examined: pi-stacking mediated immobilization and covalent crosslinking of reaction centers to graphene oxide electrodes using carbodimide based crosslinkers. Preliminary data using cycleing voltammetry shows improved current density, as well as, light dependent effects on graphene oxide performance compared to previously published work. American Chemical Society Long Island Subsection - http://www.newyorkacs.org/sub_island.php Time: 5:30pm - Social with light refreshments followed by 6:00pm Seminar Start. After Seminar Dinner: At a nearby restaurant, $25.00 per person.
