Glue With Mussels: Purdue Chemist Synthesizes Wet-Set Adhesive

Date : 02/01/2011

Clip Length : 00:05:55

In this 21st Century Chemist profile, Purdue University materials chemist and marine biologist Jon Wilker explains his work: creating a new synthetic glue by mimicking the molecular structure of the sticky substance secreted by mussels and oysters. A glue that works in wet conditions could be of particular use in surgical medicine.

The Chemical Bond Between Cloves and Nutmeg

Date : 01/28/2011

Clip Length : 00:04:07

This NBC Learn video focuses on chemical bonds by profiling eugenol and isoeugenol, two molecules with identical molecular structures except for the placement of one double bond -- a difference that makes eugenol responsible for the flavor and aroma of cloves, and isoeugenol responsible for the taste and smell of nutmeg.

The Science of Skis

Date : 12/08/2009

Clip Length : 00:05:05

Skis used by Olympic Alpine and Nordic skiers are made of fiberglass and polymers, engineered by materials scientists to give skis used in different events the flexibility, stability and torsional rigidity required. NSF-funded scientists Melissa Hines, Director of the Cornell University Center for Materials Research, and Kathy Flores, an Ohio State University materials scientist, explain how skis are made, from the core to the ski base, with help from three members of the U.S Olympic Ski Team: Julie Mancuso, Scott Macartney and Ted Ligety.
