Enantiomeric excess

Enantiomeric Excess

Piece description from the artist

This original has sold.
Enantiomeric excess is a concept from chemistry. Enantiomers refer specifically to a type of isomerism where the two molecules are identical in every way, except that they're mirror images of one another. The ability to possess a mirror image is a property called "chirality". The 3-dimensional shape of your hand is chiral. Your left and right hands are, in a sense, enantiomers of one another. Enantiomeric excess sets up the idea of chirality using a spiral, which is a chiral object in 2-dimensions. Very fine line details in black ink also represent chiral objects, but in both handedness or both enantiomers. There is a preponderance of one type of enantiomer. If you know a chemist, a biochemist, or someone who works in pharmaceuticals, :"Enantiomeric Excess", the drawing, can function as a talking point as well as art. In chiral separations, synthesis, and analysis, a chiral environment (the marker spiral) is used to sense and sort chiral molecular objects (the black ink drawings) to create a large excess of one enantiomer.

About Regina Valluzzi

Waltham, MA

Dr. Regina Valluzzi has an extensive scientific background in nanotechnology and biophysics. She has been a scientist in the chemical industry, a green chemistry researcher, a research professor at the engineering school at Tufts, a start-up founder engaged in technology commercialization, and a start-up and commercialization consultant.

Even during periods of intense activity as a scientist, Dr. Valluzzi has always held a strong interest in the visual arts and in visual information. While she majored in Materials Science at MIT, she also obtained a second degree in music and a minor in visual studies. Visual arts have managed to permeate her technical work; during her Ph.D in Polymer Science and Engineering at UMass Amherst, she completed a thesis that required advanced electron microscopy, image analysis, and theoretical data modeling. These experiences provided the visual insight and information that now influences much of her artwork.

Dr. Valluzzi’s work has been included in private collections across the US, UK, Germany, Canada, Japan, Netherlands, Switzerland, Bulgaria, Dubai and Malta, and in the corporate collection of "Seyfarth Shaw" Boston law offices around Boston. She has a selection of pieces on loan to the MIT Materials Science and Engineering Department as indoor public art. Her accomplishments include having published thirty articles in peer-reviewed scientific journals, having made several scientific patents, having been a subject matter expert for an encyclopedia chapter, and having been invited to speak at science talks across the US, Europe, and Japan.

Her newsletter is a good source of ongoing information: http://eepurl.com/daiLQ
