Presents Dr. Naomi J. Halas, Stanley C. Moore Professor at Rice University Abstract:
In recent years we have shown that certain metallic nanoparticles possess collective electronic resonances- known as plasmon resonances- that depend very sensitively on the shape of the nanostructure. This interesting observation has led to a fundamentally new paradigm- "Plasmon Hybridization"- where the collective electronic resonances in a metallic nanostructure can be understood to be a direct classical analog of the single electron wave functions of simple atoms and molecules. The Plasmon hybridization picture explains the tunability of nanoshells, a dielectric core, metallic shell nanoparticle which is the simplest nanostructure with tunable plasmon resonances. More importantly, it provides a nanoscale "design rule" for understanding the plasmon resonances in an entirely new family of plasmonic nanostructures, and for the coupling of plasmonic nanostructures to meso- and macroscopic structures such as nanowires, thin metallic films, or other structures. Controlling the resonant optical properties of nanostructures allows one to control the local field at the nanostructure surface, so these structures can be thought of as precision optical components, although they are far smaller than a wavelength of light. We can exploit these new optical components in a variety of applications, ranging from dramatic enhancement of weakly emitting fluorescent media to label-free chemical detection. In addition, by tuning plasmon resonances into the near infrared region of the spectrum, the physiological "water window" can be accessed, where blood is essentially transparent and light penetrates maximally through human tissue. We have developed a suite of applications for plasmonic nanoparticles in biomedicine, including photothermal cancer therapy, currently in clinical trials. Biography:
Naomi Halas is the Stanley C. Moore Professor of Electrical and Computer Engineering at Rice University, where she also holds faculty appointments in the Departments of Physics, Chemistry, and Bioengineering. She joined Rice following a postdoctoral fellowship at AT&T Bell Laboratories. She is author of more than 180 refereed publications, has more than ten issued patents, and has presented more than 300 invited talks. She is best known scientifically as the inventor of nanoshells, nanoparticles with tunable optical resonances that span the visible and infrared regions of the spectrum. Halas has studied their properties and pursued applications of nanoshells in biomedicine and chemical sensing. She is co-founder of Nanospectra Biosciences, Inc., a company currently commercializing a photothermal cancer therapy based on nanoshells. She is founder and Director of the Laboratory for Nanophotonics (LANP) at Rice, which supports collaborations and interactions among researchers at Rice and other institutions nationally and internationally in the emerging field of Plasmon-based optics and applications. She is a Member of the American Academy of Arts and Sciences and a Fellow of five professional societies: the American Physical Society, the Optical Society of America, the International Society for Optical Engineering (SPIE), the Institute for Electrical and Electronics Engineers, and the American Association for the Advancement of Science.

Utilizing the Ignition Quality Tester (IQT) to determine the impact of fuel physicochemical propert

Greg Bogin,Assistant Research Professor,Department of Chemical Engineering,Colorado School of Mines,Golden, COABSTRACT:The goal of increased combustion efficiency with reduced emissions has sparked increased interest in new technologies for advanced combustion engines such as Low Temperature Combustion (LTC). LTC involves the combustion of thoroughly premixed fuel and air, utilizing high compression ratios and lean equivalence ratios which produce relatively long ignition delay times (compared to typical diesel engines). LTC utilization produces two desirable characteristics: i) high engine efficiency due to high compression ratio and unthrottling, and ii) low NOx and PM emissions due to minimization of traditional high-temperature flame fronts and locally fuel-rich zones. LTC engines, however, present significant challenges as traditional engine control strategies (ignition coil control for Spark Ignition or start-of-injection timing for Compression Ignition) are not employed. Fuel mixture autoignition kinetics dictate ignition timing, resulting in significant control system decoupling. Attaining LTC using petroleum-based fuels (and eventually biofuels) is achievable through the optimal coupling of the fuel injection process with in-cylinder fluid mechanics, and an improved understanding of kinetic pathways to auto-ignition. This requires a concerted approach of experiments and numerical modeling to quantify the effects of fuel chemistry and physical properties on combustion timing, combustion efficiency, and emissions.
A comprehensive understanding of fuel effects on combustion efficiency and emissions is essential for predictive models used to design advanced combustion engines utilizing the LTC regime. It is also essential as non-petroleum based fuels, which can vary widely in fuel chemistry, are adopted. Accomplishing this task requires a research device capable of studying realistic fuels (e.g. low volatility) which are difficult to study using traditional research apparatus such as shock tubes and rapid compression machines. The Ignition Quality Tester (IQT™) is a constant volume, spray combustion device designed solely to measure ignition delay, from which a Derived Cetane Number (DCN) is calculated using ASTM method D6890-09. The experimental capabilities of the IQT have been expanded to allow investigation of fuel effects on combustion timing and emissions. In parallel, a computational fluid dynamics (CFD) model was developed using KIVA-3V and linked with CHEMKIN to provide the first significant insights into the coupling of fuel spray physics and chemical kinetics for the IQT. The coupling of experiments and modeling enables fundamental research on the physical and chemical fuel effects on combustion, with the benefit of maintaining the link to the ASTM method for DCN. The CFD model accurately and efficiently reproduces ignition behavior of n-heptane; predicting that the combustion event is governed by autoignition and that dispersed ignition events occur throughout the combustion chamber. 2-methyl-hexane (an isomer of n-heptane having similar physical properties) produces longer ignition delay (ID) times compared to n-heptane, in agreement with rapid compression machines studies. The longer ID of 2-methyl-hexane verifies that chemical kinetics dominate over the physical effects of the fuels. The longer ID also results in higher NOx emissions. Thus, the IQT can bridge the gap between fundamental fuel research and actual internal combustion engine research.
