Chemistry, the “Central Science”, has played a critical role in the economic development of Rochester. The long history of successful development of innovative technologies continues today, both at established companies and universities as well as at many area start-ups. This lecture series will highlight emerging technologies with significant chemical components that are being developed in the Rochester area. The three lectures in the 2018 program will discuss the basic science and the target products of nanophase materials, new chemistry for the stabilization and applications of alkali metals, and printing technologies for additive manufacturing. These free lectures are open to the general public - including students looking for insight into future career opportunities.

7 pm: Lecture
The volatile nature of alkali metals has limited their use, particularly in large-scale operations. While excellent conductors of energy and heat, alkali metals are costly, dangerous, and difficult to manage. SiGNa has created a portfolio of materials that retain the reactivity of the original metal while attenuating their dangerous or highly combustible properties. SiGNa’s technology for the dissolution of reactive metals into nanostructured inorganic oxides, such as silica and alumina, preserves the reactivity of the metal while controlling its propensity to react violently with water and oxygen. The resulting alkali metal solid solutions are easily handled in the lab, pilot plants, and commercial manufacturing facilities. SiGNa’s products react controllably and with predictable activation and do not require toxic solvents and cryogenic temperatures. With these materials, the speed of critical reaction times can be increased up to 90%, and processing steps can be eliminated. More recently, SiGNa has demonstrated the use of alkali metal silicides, specifically sodium silicide, as a novel method to significantly enhance the recovery of heavy crude reserves. When used as an EOR agent, alkali metal silicides have unique properties that leverage the benefits of both chemical and thermal flooding. Preliminary research demonstrates that alkali metal silicides can improve extraction rates from established wells by >40%. The history of SiGNa’s materials and the company’s current focus on oil and gas applications will be discussed.
David Wang received his B.A. in chemistry at Cornell University in 2005 and his Ph.D. in organometallic chemistry at Rutgers University in 2013. His thesis work investigated oxidative addition/reductive elimination, olefin isomerization, and olefin binding to pincer-ligated iridium metal complexes. After doing postdoctoral work at Princeton University, he began his industrial career at Eastman Kodak where his work involved small molecule synthesis supporting basic and applied research in polymer, materials, and surface chemistry. In 2018, he joined SiGNa Chemistry where his work involves materials development and application research.
