Piece description from the artist
Bingham fluids are pastes that act as solids under light stress or pressure, but flow like viscous or viscoelastic liquids once the applied stress or pressure is stronger. They are often made up of networks of particles or rope-like molecules. These constituents softly stick to each other, creating a gel-like solid. If the applied stress is too weak to unstick the constituents, the fluid remains solid. Once enough stress is applied to unstick the constituent, the paste flows. Blood is a common and complex Bingham fluid.
It takes a little time for things – even tiny particles and polymers -to stick to each other. So once the fluid is flowing, the “stickiness” may add to the effective “friction” of the fluid, but it’s less than when the fluid is sitting still. I’ve tried to capture some of the microstructural ideas and flow ideas in the details of the drawing. If you look carefully you can see some of the equations describing Bingham pastes and flows.
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.
