"Raman Spectroscopy of Nanotubes and other Nano-Carbon Systems"
Mildred Dresselhaus
Massachusetts Institute of Technology
Cambridge, MA 02139
Abstract: Carbon nanostructures have recently assumed new importance with the discovery of an anomalous quantum Hall effect in single layer graphene, which denotes one atomic layer of a bulk graphite crystal. A review is given of early work on the electronic structure of graphene (dating back to 1947), which also denotes the birth of the transistor. A brief review is given of selected carbon nanostructures leading to carbon nanotubes, graphene and graphene ribbons. Particular emphasis is given in this talk to the remarkable properties of carbon nanotubes and graphene and recent advances in the use of photophysics to reveal these unique materials properties.

"CO Oxidation on Gold/Nickel (111) Surface Alloys"
Jonathan Fischer, Jae-Gook Lee, Sylvia Ceyer
Dept. of Chemistry, 77 Massachusetts Avenue
Massachusetts Institute of Technology
Cambridge, MA 02139
Abstract: Catalytic oxidation of carbon monoxide from vehicle exhaust is an issue of great environmental and economic importance. Although Gold and Nickel do not form stable bulk alloys at room temperature, a stable surface alloy can be formed by vapor deposition of Gold on a Nickel (111) crystal. Oxygen is observed to molecularly adsorb on surfaces containing approximately 0.3-0.4 ML Au, in contrast to dissociative chemisorbtion on pure Ni(111) and low temperature physisorbtion on pure Au surfaces. This molecularly adsorbed oxygen has been characterized as peroxide and superoxide species by vibrational spectroscopy. These species, as well as loosely bound oxygen atoms produced by thermal decomposition of the oxygen molecules, have been observed to oxidize carbon monoxide to carbon dioxide at temperatures as low as 70 K.
Biography: Jonathan Fischer obtained his B.S. in Chemistry at the University of Massachusetts Lowell. He carried out undergraduate research in the areas of spectroscopy and chemical education. He is presently working on his Ph.D. in Physical Chemistry at the Massachusetts Institute of Technology in the research group of Professor Sylvia Ceyer.

"Biofuels: Promises and Challenges
Ihab H. Farag
Professor &UNH Biodiesel Group Director
Chemical Engineering Department
Abstract
The public is becoming increasingly aware of the need for alternatives to petroleum based fuels. The price of oil is increasing faster than new technologies such as gas-electric hybrids can compensate. Biofuels such as bioethanol, biobutanol and biodiesel are speculated to eventually replace petroleum fuels.
Biodiesel has emerged as an alternative fuel to petrodiesel. It is produced by catalytic esterification of lipids with alcohol. Lipids may include: used cooking oil, soybean, corn, canola, mustard seed, or Jatropha oil. Glycerin is generated as a byproduct. The Biodiesel energy output per unit of fossil energy input is usually around 3.3. This makes Biodiesel a renewable fuel. It can be used in transportation and for electricity generation. Its advantages include increased engine lubricity reducing engine wear, drastically lower emissions relative to diesel, far safer to use and transport, and ease of use in existing diesel engines. Biodiesel has a closed carbon cycle therefore it has no net emission of CO2, a major greenhouse gas. Biodiesel can be used in “neat” form, or blended with diesel in any ratio.
There is an increasing concern about agrofuels versus Biofuels. Agrofuels refer to liquid fuels from monoculture biomass, including trees, grown on a large agroindustrial scale. Agrofuels have resulted in the dilemma of using the land to grow food versus energy crops, with the consequence of increased food prices worldwide.
The basic challenge is how to balance three major issues: food security, feed security, and fuel security. Suggested approaches will be discussed.
Dr. Farag is the director and founder of the UNH Biodiesel Group and of the New Hampshire Pollution Prevention Internship Program. In Sept 1976 he joined the faculty at University of New Hampshire (UNH) after receiving his doctorate of Science (Sc.D.) from the Massachusetts Institute of Technology (M.I.T.,
Dr. Farag has successfully directed many projects, involving research, development, technology transfer, and outreach. He gave many invited briefings to the NH legislators on Pollution Prevention, Biomass, Biodiesel and Bio-Oil. He is currently directing a Project "Biodiesel fuel from Nonedible Vegetable Oils", in
Dr. Farag has been the recipient of a number of prestigious awards, the latest are the US EPA Environmental Merit Award, and the US Most Valuable Pollution Prevention (MVP2) Program award. In recognition to his outstanding involvement in International Programs, Dr. Farag was awarded the University of New Hampshire (UNH) award for Excellence in International Engagement. He has also received several Outstanding Teaching awards at MIT and UNH.
"Microplasma-based OES sensors and their use in both vacuum and atmospheric manufacturing processes"
Presented by: Paul Tyra
Vice President of Product Marketing
Verionix, Incorporated (
Abstract:
Recent advances in microplasma technology have made possible palm-sized ICP-OES sensors for the detection of gas composition in electronics, pharmaceutical and solar cell manufacturing processes. With the ability to monitor both trace elements and noble/inert gases within pressure ranges complementary to the normal operating envelopes of traditional RGA and FT-IR technologies, microplasma-based OES sensors provide engineers with new insights into process performance – in real-time, and in-situ.
A summary of recent developments in microplasmas, and in particular, Verionix’ novel ICP and SRR (Split Ring Resonator) plasmas will be presented. How the optical emissions from these microplasmas are used to monitor and control a variety of production-centric applications will also be reviewed. A demonstration of Verionix’ atmospheric-pressure gas composition sensor will be provided.

"Europium Doped Gallium Nitride Films for Potential Use in a Novel LED Architecture".
Joseph Laski OSRAM
Abstract
An alternative approach to tuning the emission color of an LED is described. In contrast to the conventional strategy of modifying the alloy composition of the active layer of an LED structure to achieve varying band gap emission wavelengths, we report on attempts to dope nitride-based semiconductors with rare earth (RE) ions to facilitate internal non-radiative energy transfer from the semiconductor to the RE, resulting in visible RE emission directly from the chip. The presentation focuses on the design and use of a research grade MOVPE (metalorganic vapor-phase epitaxy) reactor to deposit RE doped nitride films, in a process similar to that which is used in commercial LED manufacturing. Results are presented for a europium doped GaN film, representing a first step toward our goal.

"Quantum Well, Quantum Dot, and Quantum Cascade Nanomaterials and Devices – Making Electrons Work Hard"
William D. Goodhue
Dept. of Physics and Photonics Center, University of Massachusetts Lowell
One University Avenue, Lowell, MA 01854
Abstract: Over the past decade quantum well and dot devices have been established as one of the building blocks of modern photonics technology. During this period UMass Lowell has established a significant III-V semiconductor quantum device growth facility in the school’s Photonics Center. This talk will discuss the important role electrons play in resonant tunneling devices and how that role has transitioned to quantum dot devices and terahertz quantum cascade lasers. Quantum dot and terahertz laser work at the Center will be featured.
