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.  

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.

LPTH Press Release - LightPath Technologies Wins Large Precision Molded Glass Optics Contract from Renishaw 4-6-2017

LightPath Technologies Wins Large Precision Molded Glass Optics Contract from Renishaw
For Immediate Release:

ORLANDO, FL – April 6, 2017- LightPath Technologies, Inc. (NASDAQ: LPTH) (“LightPath,” the “Company” or “we”), a leading vertically integrated global manufacturer, distributor and integrator of proprietary optical and infrared components and high-levelassemblies, today announced that it was selected by Renishaw plc (LSE: RSW), a United Kingdom-based world leader in metrology technology and products, to be a designated supplier of two types of glass molded lenses for Renishaw’s RESOLUTE optical encoder products. The substantial contract from Renishaw has secured its high volume requirement for the foreseeable future.  Certain details pertaining to the contract were not disclosed.

Engineers from LightPath and Renishaw collaborated to achieve the optimal balance of performance and cost for this unique application.  LightPath’s advanced precision glass molding expertise along with proprietary coating design and technologies enable a repeatable process that is scalable to high volume production and has created a product like no other.

Jim Gaynor, President and Chief Executive Officer of LightPath, commented:  “The contract from Renishaw was borne from a continuing partnership with our distribution partner AMS Technologies.  AMS Technologies, as Europe’s leading solution provider and distributor for optical, power and thermal management technologies, has joined forces with LightPath for its advanced precision molded optical lens capabilities to develop mass market and proprietary products for Renishaw and other international customers.  This contract from Renishaw means that two large scale projects have now been awarded to LightPath in the last 12 months, demonstrating the continued successful implementation of our global molded lens growth strategy.”

RESOLUTE is a true-absolute, fine pitch optical encoder system that has excellent dirt immunity, and an impressive specification that breaks new ground in position feedback.

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

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.

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.
