"Doing Chemistry at the Art/Archaeology Interface"
Abstract: The archaeological chemical rewards of spending a sabbatical year in Israel and Italy will be discussed along with modern methods used to examine both ancient and modern artifacts. The archaeological work in Israel involved analysis of ancient pigments and dyes found on excavated materials from caves in the Judean desert and the ancient fortress of Masada. Textiles from the "Cave of the Warrior" were examined from their pigment content. The work in Italy involved examination of medieval artists' manuals for recipes for blue pigments, which were then carried out and characterized, with some surprising results. Additional applications of the methods of archaeological chemistry to such famous artifacts as the forgeries of Han van Meegeran and the Shroud of Turin will be discussed, including some evidence that the radiocarbon date of the shroud may not be valid because of fire damage it experienced by the Shroud in 1532.
Pros and cons will be discussed.

Dudley Herschbach was born in San Jose, California (1932) and received his B.S. degree in Mathematics (1954) and M.S. in Chemistry (1955) at Stanford University, followed by an A.M. degree in Physics (1956) and Ph.D. in Chemical Physics (1958) at
Harvard. After a term as Junior Fellow in the Society of Fellows at Harvard (1957-1959), he was a member of the Chemistry Faculty at the University of California, Berkeley (1959-1963), before returning to Harvard as Professor of Chemistry (1963), where he became Baird Professor of Science (1976-2003) and is now Emeritus. In 2005 he joined the Department of Physics at Texas A & M University, visiting each year in the Fall semester. At Harvard, he has served as Chairman of the Chemical Physics program (1964-1977) and the Chemistry Department (1977-1980), as a member of the Faculty Council (1980-1983), and Co-Master with his wife Georgene of Currier House (1981-1986). His teaching included graduate courses in quantum mechanics, chemical kinetics, molecular spectroscopy, statistical mechanics, and collision theory, as well as
undergraduate courses in physical chemistry and (for 20 years) general chemistry for freshmen, his most challenging assignment. Currently he gives a freshman seminar course on ‘Molecular Motors: Wizards of the Nanoworld.”
He is engaged in several efforts to improve K-16 science education and public understanding of science. He serves as Chair of the Board of Trustees of the Society for Science and the Public, which publishes Science News and conducts the Intel Science Talent Search and the Intel International Science and Engineering Fair. He has also appeared in several TV and radio programs designed to foster appreciation of science and has given many lectures with that aim to school audiences, alumni clubs, and the like. Some recent titles: "Einstein as a Student;" "The Scientific Education of John Adams;" "Benjamin Franklin's Scientific Amusements;" "The Impossible Takes a Little Longer."
He is a Fellow of the American Academy of Arts and Sciences, the National Academy of Sciences, the American Philosophical Society, and the Royal Chemical Society of Great Britain; also an honorary life member of the Association for Women in Science, and the New York Academy of Sciences. His awards include the Pure Chemistry Prize of the American Chemical Society (1965), the Linus Pauling Medal (1978), the Michael Polanyi Medal (1981), the Irving Langmuir Prize of the American Physical Society (1983), the Nobel Prize in Chemistry (1986), jointly with Yuan T.

"Design and Synthesis of N-rich Energetic Materials "
Conventional energetic materials currently in use at army training ranges negatively impact the environment when released through Unexploded Explosive Ordnance (UXO), low-order, and high-order detonations. This, in turn, requires costly, long-term range remediation and clean-up efforts. The development of replacement materials that are environmentally benign and also meet or exceed performance and vulnerability requirements will ensure that army operational ranges and munitions production facilities will remain available and sustainable in support of transformation and objective forces. Toward this end, a combined experimental and theoretical effort has been implemented, with a focus on developing novel high-nitrogen and high-oxygen-containing energetic materials as environmentally acceptable replacements for RDX , which is a leading contaminant of training ranges.
We have considered different possibilities for the processing of high-nitrogen compounds. While all nitrogen species would be ideal materials due to their high energy content and extremely favorable gaseous byproducts (with a large percentage of N2), there are only very few candidates that have been identified and characterized. In addition, some candidates have significant stability problems. Some high nitrogen molecules which do not include oxidizing groups show promise as candidates for propellant charges and for high explosives, but these molecules do not release enough energy to act as a suitable replacement for those explosives. However, the combination of high-nitrogen compounds with strongly oxidizing groups should be advantageous in delivering the explosive energy required. Because nitrogen-rich compounds suffer from stability issues, we have attempted to design systems that take advantage of π aromatic delocalization. These could include five-membered cyclic molecules that contain three, four or five nitrogens (triazoles, tetrazoles and pentazoles, respectively). Triazoles often do not possess enough intrinsic energy to be suitable candidates for high explosives, and pentazole derivatives are usually far too sensitive and unstable for any application. The tetrazole compounds offer a good compromise between high nitrogen content and reasonable kinetic stability. Moreover, six-membered tetrazine compounds have also been included in the study.

"Atomic-Scale Studies of Fundamental Properties and Processes in Shock-Loaded Energetic Materials"
In the instants immediately following shock wave excitation, polyatomic molecular crystals are subjected to highly non-hydrostatic stresses and highly non-thermal distributions of kinetic energy within the system.
Depending on the details of chemical structure and space group, crystal orientation, and shock strength relative to the orientation-dependent Hugoniot elastic limit, relaxation may occur via polymorphic transitions, melting, or other inelastic deformation processes; or, for sufficiently strong shocks, via chemical reactions. Such transformations in molecularly-complex crystals are more complicated than in the case of metals, and are characterized, in general, by changes in translational symmetry; changes in orientation of molecules in the crystal lattice, the latter of which typically is of symmetry class lower than cubic; and changes in shape or point group of the molecule. In some cases involving energetic molecular crystals the melting transition is accompanied by strongly exothermic chemical reactions that further complicate the situation. We are seeking to understand through the use of atomically-resolved molecular dynamics simulations the detailed pathways and time scales by which such non-equilibrium states relax toward thermo-mechanical equilibrium for energetic crystals, and how these lead to structural transformations in the materials. Recent results for shocked RDX and nitromethane crystals will be presented.

"Molecules to Mozzarella: The Chemistry of Cheese"
Coagulation of milk, removal of whey, and ripening are all required when making cheese, and chemistry is involved every step of the way. This non-technical talk describes the procedure from raw milk to final product, and illustrates the differences between cheese types, including the development of the many flavors in cheese.
Biography. Michael H. Tunick received a B.S. in Chemistry from Drexel University in 1977. He was a student trainee at the Eastern Regional Research Center of the U.S. Department of Agriculture in Wyndmoor, PA, and was hired as a chemist upon graduation. He performed research on treatment of tannery waste with the Hides and Leather Laboratory until 1983, when he was transferred to what is now the Dairy Processing & Products Research Unit. He pursued a Ph.D. in Physical-Analytical Chemistry on a part-time basis during this period, receiving the degree from Temple University in 1985. He also became a research chemist in that year and was involved in a number of projects, including detection of mislabeled cheese and development of low-fat Mozzarella for the National School Lunch Program. He currently relates the effects of processing to changes in composition, texture, and microstructure of cheese and extruded whey proteins. He is the Secretary and a Past Chair of the ACS Division of Agricultural and Food Chemistry, and is Councilor and Past President of the Thermal Analysis Forum of Delaware Valley.

"Condensation Polymerization: Applications in Conjugated Polymers and Nanocomposites"
Postdoctoral candidate seminar for Javier Vela
Abstract: Part A: Both traditional and nontraditional (olefin metathesis) polycondensation methods can be exploited in the design strategies of extended conjugated systems. We have demonstrated how these two methods may be used to build up defect-free conjugated systems. Specifically, homologous series of oligo(p-phenylene vinylene)s /their derivatives and hetero-atom containing linear /macro cyclic conjugated systems have been synthesized. In some cases, Ru based Grubbs system with high functional group tolerance has been exploited as initiators/catalysts. All materials represent architectures of significant interest, particularly for light emitting applications.
Part B: Gas phase pulsed plasma enhanced chemical vapor deposition (PECVD) can be used to deposit ultra thin, conformal polymeric films/coatings on the surfaces of metallic and non-metallic nanomaterials. Both the thickness and properties of this polymeric film can be tuned, including deposition of reactive organic functional groups on the surfaces of nanomaterials. Our studies have demonstrated that these functionalized nanomaterials can be covalently linked, via polycondensation reactions, with high performance thermosetting resin (epoxy, polyurethane) to yield hybrid nanocomposites with improved physical properties. The properties of the inorganic/organic nanocomposites may be further controlled by varying nanomaterials (type, size), surface functional groups and resin.

"Systematic Study of Chalcogenide Nanostructured Gels as a Function of Density and Building Block"
Postdoctoral candidate seminar for Javier Vela
Here, we demonstrate a general sol-gel methodology to assemble metal chalcogenide nanoparticles into porous aerogel frameworks, with the long term goal to develop a new class of porous semiconductors with potential photovoltaic, sensing or catalytic applications. This methodology consists of three steps: first, nanoparticle formation and thiolate ligand exchange; second, gelation through controlled removal of surface thiolate groups; and third, supercritical CO2 drying to maintain the wet gel structure and generate the aerogel. With the aim of obtaining more insight and engineering intrinsic gel properties, a systematic study to investigate quantum confinement effects in a low dimensional gel framework was conducted in the CdSe system, the interactions between CdSe quantum dots and the band gap values of CdSe gels were found to be controlled by their bulk monolithic densities. Subsequently, the effects of nanoparticle shape on the morphology and properties of the resultant CdSe aerogel were also studied. In this project, differently-shaped CdSe nanoparticles (dot, rod, branched and hyperbranched) were employed to investigate the effect of the shape of the building block on the resultant assembly morphology and properties, including surface characteristics and optical properties. Finally, a novel synthesis of discrete and dispersible MoS2 nanoparticles was developed enroute to our long term goal to create a porous and freestanding aerogel-based hydrodesulfurization catalyst.

"Environmental Forensics and Analytical Atomic Spectrochemistry"
Environmental forensics is a new subject area relating to courtroom or litigation proceedings and the fact basis for mediated or negotiated transactions involving environmental matters. Environmental forensic investigations often deal with historical release of contaminants and attempt to establish who caused the contamination, when and how the contamination occurred, how extensive the contamination was, what levels of contamination exposure existed, and how valid the test results were. Plasma spectrochemical analysis has been applied to a large variety of environmental and forensic materials to identify and quantify their elemental concentrations, isotopic compositions, and metal compound forms. Specifically, inductively coupled plasma (ICP) atomic emission (ICP-AES) and mass spectrometry (ICP-MS) provide powerful elemental analysis tools for air monitoring, biota analysis, soil and sediment analysis, radionuclide determinations, and water and ecological monitoring. The features of plasma spectrochemistry will be described, and ICP analyses of environmental and forensic materials will be reviewed with emphasis on chemometric data interpretation for source identification. The unique applications of laser ablation (LA-ICP-MS) for microsamples and especially crime scene samples will be demonstrated. Elemental speciation with combined separation and ICP-MS tools also will be introduced.
Biography of Dr. Barnes. Ramon Barnes is director of the University Research Institute for Analytical Chemistry, Professor Emeritus of Chemistry at the University of Massachusetts, editor of the ICP Information Newsletter (1975-), and chairman of the Winter Conference on Plasma Spectrochemistry (1980-).

"Applications of Micro Free Flow Electrophoresis"
In free flow electrophoresis (FFE) a thin stream of sample is continuously introduced into a planar flow chamber. An electric field is applied perpendicularly to the flow through the separation chamber. Analytes are deflected laterally in the electric field according to their electrophoretic mobility giving rise to individual stream paths. FFE has recently been miniaturized into a microfluidic format (uFFE), requiring less sample and reagents, a simplified flow profile and better heat dissipation.
The continuous nature of uFFE separations suggests a number of novel analytical applications. A single separation can be monitored over long periods of time for high sensitivity measurements. We have demonstrated a 20-fold improvement in signal to noise by averaging 500 images over a 2 minute period. uFFE can also be used to continuously monitor a dynamically changing sample. We have demonstrated how introducing a buffer gradient into the uFFE device can be used to efficiently optimize a range of separation conditions or estimate dissociation constants in as little as five minutes. We have also explored introducing a gradient at the sample channel. For example, we have titrated a fluorescently labeled aptamer with increasing concentrations of its protein target. Due to the continuous nature of gradient uFFE, complete coverage of the binding curve is possible in as little as five minutes. Lastly, continuous uFFE separations offer a number of advantages for microscale preparative applications such as aptamer isolation and subcellular organelle analysis.
