Science Fair Projects on Plants with Aspirin

May 1, 2012 | Leave a Comment

Before we begin, you need background information for your science fair experiment. Aspirin, also called, acetylsalicylic acid, is a pharmaceutical drug that is in the family of salicylates (salicylic acid – SA). It is a colorless crystalline organic acid and is used in synthesis and is a plant hormone. SA is a phytohormone and is [...]

Chemistry Nobel Prize 2010

October 10, 2010 | Leave a Comment

The Nobel Prize in Chemistry 2010 was awarded jointly to Richard F. Heck, Ei-ichi Negishi and Akira Suzuki “for palladium-catalyzed cross couplings in organic synthesis”. This chemical tool has vastly improved the possibilities for chemists to create sophisticated chemicals, for example carbon-based molecules as complex as those created by nature itself. In order to create [...]

Archaeopteryx: The Dinobird

May 17, 2010 | Leave a Comment

X-Rays Reveal Chemical Link Between Birds and Dinosaurs. Researchers have found that a 150 million year old “dinobird” fossil, long thought to contain nothing but fossilized bone and rock, has been hiding remnants of the animal’s original chemistry. Using the bright X-ray beam of the Stanford Synchrotron Radiation Lightsource, located at the Department of Energy’s [...]
