Solar Cells, D. Venkataraman

Science and Engineering Saturday Seminars

Solar cells convert the sun's energy into electrical energy. In this workshop, I will discuss the processes involved in solar cell and various types of solar cells that are being developed as an alternative to silicon solar cells. I will also demonstrate how students can build a solar cell from readily available materials.

Synthesizing Polyhydroxylated Indolizidines From D-Glucopyranoside, Stephanie Bryson

SURE (Stonehill Undergraduate Research Experience)

The individual sugars that constitute more complex carbo-hydrates are joined together by glycosidic bonds. Glycosidase enzymes catalyze the hydrolysis of these glycosidic bonds. The action of glycosidases plays an important role in viral infections, cancer, and diabetes. Iminosugars are nitrogen containing sugar analogs that are known to inhibit glycosidase function. The main objective of this research is to synthesize four of the possible 32 stereoisomers of a tetrahydoxylated indolizidine iminosugar (Figure 1) starting from a commercially available D-glucopyranoside. After synthesizing pyrrolidine 6 (39.3%), a ring-closing metathesis was performed to generate the indolizidine 7. A ruthenium catalyzed dihydroxylation followed by acetylation …
