Abstract:
Today, combustion of fuels is responsible more than 70% of world’s electricity production and is the only solution for mass air and space transportation, and is expected to remain the same at least for the next 50 years. Combustion is the process of converting chemical energy to thermal energy at high temperatures and is a highly complex reacting problem involving coupled thermal, mass, and fluid transport.  However, there is an increasing demand for better efficiency and reducing emissions due to dwindling energy resources and concerns with environmental impact of pollution. Therefore it is important to understand the details of these phenomena. UCF’s shock tube and novel laser diagnostic techniques are used to investigate to investigate various problems relevant to advanced combustion systems under practical conditions. The strategy of using shock tubes provide an ideal device for acquiring ignition delay times, species concentration time-histories, and reaction rates while laser-based diagnostic studies are non-intrusive, provide in-situ measurements (e.g., concentration of individual species including trace species, and temperature), and have fast-time response (micro-second). In addition to providing crucial knowledge about the reacting systems, measurements will provide critical validation targets for computational fluid dynamic (CFD) modelers.  

Biography:
Dr. Subith Vasu, is an expert in combustion, diagnostics for combustion, fire, and emissions techniques with over ten years of experience in the field. His research group at is interested in studying oxidation and pyrolysis chemistry in gas-phase and heterogeneous catalytic systems, and modeling reaction systems. Also, his expertise and experience lies in the field of developing laser diagnostics to detect combustion (e.g., OH, H, CH4, fuel) and pollutant species (e.g., soot, CO2, CO, etc.), optimizing fuels (fossil, biofuels, etc.) with respect to their combustion and emission properties, and understanding, chemically reactive systems. Dr. Vasu is active in various professional services, has served as session chair in important technical meetings, is the author of more than 45 journal articles with an h-index of 16.  He is also a reviewer for numerous journals and has been regularly invited to evaluate research proposals for DOE, AFOSR, NASA, and NSF. Currently he has ongoing projects funded by FAA, ACS, NASA, DOE, DoD and industry. Two of these are young investigator and equivalent awards: DTRA YIP 2015, ACS PRF Doctoral New Investigator 2015. He became the fastest person (in 4 years) to win the 2016 UCF Reach for the Stars Award, which is the highest award given to early career faculty including both assistant and associate professors at UCF.

NSTC/CREOL Distinguished Seminar: "Infrared near-field microscopy and spectroscopy“ by Dr. Fritz Keilmann, 4.10.17/3:30PM-4:30PM/CREOL RM 103

NSTC/CREOL Distinguished Seminar: "Infrared near-field microscopy and spectroscopy“ by Dr. Fritz Keilmann
Monday, April 10, 2017 3:30 PM to 4:30 PM
CREOL Room 103

Dr. Fritz Keilmann Ludwig-Maximilians-Universität

Abstract:
Near-field optical microscopy (by scattering from an AFM tip, s-SNOM) returns local absorbance from a tiny volume of only (20 nm)^3 under the tip apex, thus enabling VIS-to-IR-to-THz mapping at exciting 20-nm resolution. The mid-infrared is ideal for nanoscale chemical recognition by vibrational and phonon contrasts (FTIR). Near-field techniques now offer nano-FTIR, i.e. FTIR at nanometric spatial resolution. For this, broadband coherent MIR sources are essential and higly desirable, especially when combined with dual-comb operation. Application highlights will be presented of finding and characterizing natural nanoscale inhomogeneities, chemical as well as structural, in organic solar-conversion films, in bone/shell biomineral matter, and in slices through a cometary dust particle. Nano-FTIR is no less than the continued success story of FTIR-based chemical analysis into resolutions hundreds, if not thousands of times better than previously attainable. It is a highly welcome solution to nanoanalysis requirements in all nanotechnologies and nanosciences.

Biography:
Fritz Keilmann studied meteorology and physics in München and received a Dr. rer. nat. for research on infrared plasma diagnostics. As postdoc of Ali Javan at MIT he developed antenna-based harmonic mixing and high-power THz lasers.  He has been at the Max-Planck Society from 1973 to 2012: Initally at the MPI für Festkörperforschung Stuttgart, he pioneered far-infrared nonlinear optics and spectroscopy of solids, and investigated phonon physics, microwave biological effects, carrier dynamics of semiconductors, far-infrared ellipsometry of superconductors, and cyclotron-pumping microscopy of quantum-Hall edge states. In 1995 he relocated to the MPI für Biochemie Martinsried where he pioneered infrared scattering near-field microscopy, and also dual-frequency comb Fourier-transform infrared spectroscopy.   From 2007 - 2012 he was with the MPI für Quantenoptik Garching, in the DFG Cluster "Munich-Centre for Advanced Photonics", developing broad-band infrared spectroscopic near-field microscopy.  He has been awarded the Kenneth J. Button prize 2009.  Besides operating his firm LASNIX, he is presently a Scientific Advisor to Neaspec GmbH, producer of near-field infrared microscopes, and continues his research at Ludwig-Maximilians-Universität, München, investigating soft matter and biological nanocomposites.

Abstract: 
Light scattering and transport in disordered media has been extensively studied. On the fundamental side, the possibility to study coherent scattering (speckles) in optics has been an essential tool in mesoscopic physics. On the  applied  side,  methods  and  techniques  have  been  developed  for  sensing  and  imaging  in  complex  media.  New trends have emerged recently with the possibility to control light propagation using disordered materials.
In this talk we will review recent results in the theory of light transport (diffusion) and scattering (speckles) that predict unexpected behaviors of interest for the control of light matter-­-interaction.
We will discuss an invariance property of the average path length in a wave diffusion process [1], and the first measurement demonstrating this invariance [2].
In the study of speckle patterns, we will show that a spatial correlation between the reflected and transmitted intensities  persists  even  in  the  multiple  scattering  regime  [3].  This  makes  possible  to  quantify  the  level  of  information on a transmitted speckle that can be deduced from a measurement of the reflected part only. We will finally address the influence of correlations in the disorder on the scattering strength. In the case of hyperuniform materials (a specific class of correlated materials), we will show that disordered materials that are both dense and transparent can be designed [4].
I am indebted to O. Leseur, N. Fayard, A. Goetschy and R. Pierrat with whom most of this work was done.
