2010 Nichols Medalist

Professor Tobin J. Marks

Northwestern University

1:00 p.m.           Welcome


Mr. Frank R. Romano,   2010 Chair, ACS New York Section, Agilent Technologies


1:05 p.m.           Opening of the Distinguished Symposium


Dr. Hiroko Karan,   2011 Chair-Elect, ACS New York Section, City University of New York - Medgar Evers College


1:15 p.m.           Nanowires as a Platform for Nanoscience and Nanotechnology


Professor Charles M. LieberHarvard University

Advances and breakthroughs in nanoscience depend critically on development of nanostructures whose properties are controlled during synthesis. This presentation focuses generally on this concept using nanowires as a platform material. First, the synthesis of complex modulated nanowires, which has led to their emergence as a central material in nanoscience, and implementation of nanowires to investigate fundamental properties and performance limits of photovoltaic devices will be reviewed. Second, the development of active interfaces between nanowire nanoelectronic devices and biological systems will be discussed. Last, a critical review of progress made and scientific challenges that remain will be presented.


2:00 p.m.           Organic Electronics and Optoelectronics: Learning from Tobin



Dr. Mark A. Ratner,    Northwestern University

The areas of organic electronics and optoelectronics have been enriched by the research of the Marks group in subfields from transistors to nonlinear optics to nanocapacitors to light-emitting diodes to conducting oxides to photovoltaics. In each, Marks has combined synthesis, measurement and imagination, to produce very significant advances in these materials and devices. In this talk, I will sketch a few of the previous achievements in the Marks group (especially ones where theory was of some help), and finally I will venture some remarks on the current set of problems that the Marks lab is attacking.


2:45 p.m.           Design, Function, an Commercial Application of Shape Selective Catalysts for the Petrochemical Industry



Dr. David L. Stern  ExxonMobil Refining & Supply

Shape selective molecular sieves have enabled the world scale production of high purity aromatics, via control of reaction mechanism/kinetics, and molecular diffusion. In this talk, we demonstrate techniques for treatment of zeolites, enabling high differentiation of molecules with modest differences in sterics. The centerpiece is a permanently selectivated ZSM-5 catalyst, achieving over 98% para-selectivity in toluene disproportionation. Characterization results find a > 5,000 increase in diffusion resistance, selective titration of surface Brönsted acid sites, and microscopic and chemical evidence of the selectivation layer. Variants of this catalyst have been commercialized in over 20 commercial units employing the PxMaxsm and XyMaxsm technology.



3:30 p.m.           Coffee Break



4:00 p.m.           Synthesis and Use of 3-D Heterostructured Materials


Dr. Galen D. Stucky  Univeristy of California - Santa Barbara

3-D heterostructured materials with spatially distinct structured domains that have collateral compositions and functions are playing an increasingly important role in catalytic, thermoelectric, photovoltaic, structural and biomedical applications. From a practical perspective, the integrated atomic or molecular assembly of such systems can provide a simplified synthetic route to a composite system that simultaneously addresses in a complementary or synergistic way two or more functional needs for a given application. This talk will describe selected examples of multifunctional material synthesis, design and use in the above areas.


4:45 p.m.           Self-Assembly Process for Fabricating Unconventional Organic, Organometallic, and Inorganic Electronic Circuitry



Professor Tobin J. Marks,   Northwestern University

Nichols Medalist

Chemists are exceptionally skilled at designing and constructing individual molecules with the goal of imbuing them with defined chemical and physical properties. However, the task of rationally assembling them into organized, functional supramolecular structures with precise, nanometer-level control is a daunting challenge. In this lecture, approaches to addressing this problem are described in which the ultimate goal is the fabrication of organic molecular and macromolecular, and other unconventional electronic circuitry by high throughput, large area printing techniques. Issues here concern not only the rational design of high-mobility p- and n-type organic and non-organic semiconductors for CMOS electronics, but also modular high-k dielectrics with ultra-large capacitance, low leakage, high breakdown fields, and radiation hardness. It is seen that these approaches can be successfully applied to organic, organometallic, and inorganic semiconducting materials.
