	Tuesday, November 27, 2012 Turning a Single Molecule into an Electric Motor Reem-Kayden Center Laszlo Z. Bito '60 Auditorium A lecture by Charlie Sykes Tufts University In stark contrast to nature, current manmade devices, with the exception of liquid crystals, make no use of nanoscale molecular motion. In order for molecules to be used as components in molecular machines, methods are required to couple individual molecules to external energy sources and to selectively excite motion in a given direction. Significant progress has been made in the construction of molecular motors powered by light and by chemical reactions, but electrically-driven motors have not been demonstrated yet, despite a number of theoretical proposals for such motors. Studying the rotation of molecules bound to surfaces offers the advantage that a single layer can be assembled, monitored and manipulated using the tools of surface science. Thioether molecules constitute a simple, robust system with which to study molecular rotation as a function of temperature, electron energy, applied fields, and proximity of neighboring molecules. A butyl methyl sulphide (BuSMe) molecule adsorbed on a copper surface can be operated as a single-molecule electric motor. Electrons from a scanning tunneling microscope are used to drive directional motion of the BuSMe molecule in a two terminal setup. Moreover, the temperature and electron flux can be adjusted to allow each rotational event to be monitored at the molecular-scale in real time. The direction and rate of the rotation are related to the chiralities of the molecule and the tip of the microscope (which serves as the electrode), which illustrates the importance of the symmetry of the metal contacts in atomic-scale electrical devices.

	Friday, April 27, 2012 Exploring Alternative Routes to the Origin and Evolution of RNA-like Polymers Campus Center, Multipurpose Room 13th Annual Mid-Hudson ACS Undergraduate Chemistry Research Symposium Plenary Lecture Nicholas V. Hud Professor of Chemistry School of Chemistry and Biochemistry Georgia Institute of Technology NSF-NASA Center for Chemical Evolution NASA Astrobiology Institute Center for Ribosome Evolution A leading hypothesis for the nature of early life on Earth is that RNA once stored genetic information and catalyzed chemical reactions, before the appearance of DNA and protein enzymes. Despite considerable enthusiasm for this “RNA world” hypothesis, it is difficult to imagine how RNA was formed without the aid of protein enzymes. Persistent challenges to an acceptable prebiotic route to RNA polymers include the lack of a robust process for nucleobase selection (How were Watson-Crick base pairs chosen?), nucleoside formation (What reaction joined the nucleobases to ribose?), and nucleotide polymerization (How did the backbone of RNA form without a highly evolved polymerase?). As a possible solution to these challenges, we are investigating the possibility that RNA was preceded by a polymer that would have assembled more easily than RNA, being comprised of a different backbone and different nucleobases, and with its synthesis aided by other molecules present on the prebiotic Earth. Our experimental studies have demonstrated that small molecules that intercalate nucleic acids, similar to dye molecules commonly used to visualize DNA, can greatly facilitate the polymerization of short oligonucleotides. Results from other studies are showing how reversible backbone linkages would have facilitated polymer growth and early sequence evolution of the earliest RNA-like polymers.
