Original archival ink drawing, 8″ h x 10 ” w on acid free paper. Signed on front.
Ships free in the USA (or pick it up in Boston). Please inquire about shipping to other locations – I can usually cover most of the costs. Original paintings from my shop ship fully insured with a typical turnaround time of roughly 10 business days (less for small items). Once they’re with the shipper, actual transit times vary by destination.
I will gladly exchange or refund work that you do not like if notified within 30 days of receipt. Customer pays the shipping on returns and/or exchanges. Most people like them better in person.
Print and original leasing is available through Turning Art (but you’ll have to sign up with them)
Dendrimers are branched polymers that start from multifunctional monomers. Depending on the number of branches, the molecule stiffness and the length between branches, they can form structures with a dense outer surface and a fairly hollow core. This property is useful in creating complex nanoparticles. For example gold or silver or a fluorescent nanocrystal can be grown in the hollow core of the dendrimers. The outside of the dendrimer can keep the nanoparticles in the cores separated and also provides chemical properties – for example a water soluble dendrimer can be used to make stable gold nanoparticles in aqueous solution. Metal nanoparticles, if small enough, can lack the electronic levels and density of states to be truly metallic (not enough electrons to make a conduction band). These small particles are often semiconducting, with brilliant band gap colors that depend on the size and crystalline perfection of the embedded nanoparticles.
