Density of States

Piece description from the artist

A chemical physics themed mixed media painting. Density of states refers to the number of energy levels available to delocalized electrons. In molecules, metals have more electrons and organometallic compounds have a higher density of states than light element organic compounds. In Materials Science, metallically bonded solids have a high density of states and are typically conductive, but nanoparticles of the same composition are often only semiconductive because there aren't enough electrons and density of states for good cunduction.

Abstracted kekulke diagrams of everal organometallic molecules and one nanoparticle (3-D, not kekulke) are depicted in relief using a pastry bag extrusion to create fanciful textures and emphasis on important atoms. Regions of high electron delocalization are gilded, and transition metals are truly sparkly. The background features raised jagged lines in patterns typical of density of states diagrams in Chemical Physics and Molecular Quantum Mechanics, and bits and pieces of density functional integrals are scattered throughout.

I have known a large number of chemists, and I habe seen how they pursue the synthesis of difficult, complex "cool functional" molecules. Since these molecules can be like tiny holy grails, it only makes sense to add gold gilding on the phenyl rings and other areas of high electron delocalization. Also – the metallic mirror shine is a direct result of conductivity, density of states, and electron delocalization.

Perfect big occasion gift for a chemist, decor for areas near where the chemists are located at work, office decor for a chemistry professor or group leader, or for any person or entity working in nanotechnology, supramolecular chemistry, molecular catalysis, organometallic chemistry, or chemical physics. I will provide a higher resolution file as soon as I've cleaned one.

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:
