EPA Handbook: Optical and Remote Sensing for Measurement and Monitoring of Emissions Flux of Gases and Particulate Matter
EPA Handbook: Optical and Remote Sensing for Measurement and Monitoring of Emissions Flux of Gases and Particulate Matter EPA 454/B-18-008 August 2018 EPA Handbook: Optical and Remote Sensing for Measurement and Monitoring of Emissions Flux of Gases and Particulate Matter U.S. Environmental Protection Agency Office of Air Quality Planning and Standards Air Quality Assessment Division Research Triangle Park, NC EPA Handbook: Optical and Remote Sensing for Measurement and Monitoring of Emissions Flux of Gases and Particulate Matter 9/1/2018 Informational Document This informational document describes the emerging technologies that can measure and/or identify pollutants using state of the science techniques Forward Optical Remote Sensing (ORS) technologies have been available since the late 1980s. In the early days of this technology, there were many who saw the potential of these new instruments for environmental measurements and how this technology could be integrated into emissions and ambient air monitoring for the measurement of flux. However, the monitoring community did not embrace ORS as quickly as anticipated. Several factors contributing to delayed ORS use were: • Cost: The cost of these instruments made it prohibitive to purchase, operate and maintain. • Utility: Since these instruments were perceived as “black boxes.” Many instrument specialists were wary of how they worked and how the instruments generated the values. • Ease of use: Many of the early instruments required a well-trained spectroscopist who would have to spend a large amount of time to setup, operate, collect, validate and verify the data. • Data Utilization: Results from path integrated units were different from point source data which presented challenges for data use and interpretation. -
Federico Capasso “Physics by Design: Engineering Our Way out of the Thz Gap” Peter H
6 IEEE TRANSACTIONS ON TERAHERTZ SCIENCE AND TECHNOLOGY, VOL. 3, NO. 1, JANUARY 2013 Terahertz Pioneer: Federico Capasso “Physics by Design: Engineering Our Way Out of the THz Gap” Peter H. Siegel, Fellow, IEEE EDERICO CAPASSO1credits his father, an economist F and business man, for nourishing his early interest in science, and his mother for making sure he stuck it out, despite some tough moments. However, he confesses his real attraction to science came from a well read children’s book—Our Friend the Atom [1], which he received at the age of 7, and recalls fondly to this day. I read it myself, but it did not do me nearly as much good as it seems to have done for Federico! Capasso grew up in Rome, Italy, and appropriately studied Latin and Greek in his pre-university days. He recalls that his father wisely insisted that he and his sister become fluent in English at an early age, noting that this would be a more im- portant opportunity builder in later years. In the 1950s and early 1960s, Capasso remembers that for his family of friends at least, physics was the king of sciences in Italy. There was a strong push into nuclear energy, and Italy had a revered first son in En- rico Fermi. When Capasso enrolled at University of Rome in FREDERICO CAPASSO 1969, it was with the intent of becoming a nuclear physicist. The first two years were extremely difficult. University of exams, lack of grade inflation and rigorous course load, had Rome had very high standards—there were at least three faculty Capasso rethinking his career choice after two years. -
Stephan Hruszkewycz Tuesday, September 25 • 4 Pm • Tech L211
THE MATERIALS SCIENCE AND ENGINEERING DEPARTMENT COLLOQUIUM SERIES PRESENTS: Stephan Hruszkewycz Assistant Physicist, Argonne National Laboratory Opportunities for materials science with coherent x-ray diffraction imaging Recent progress in 3D coherent x-ray diffraction imaging methods can enable high resolution structural imaging of nano-structured crystalline materials under operating conditions. In this talk, I discuss developments in Bragg coherent diffraction imaging (BCDI) that aim to broaden the envelope of materials science problems that can be addressed with the technique. Following an introduction of the basic principles of the method, two specific topics will be discussed: 1) BCDI at high x-ray energies that provide dramatic penetrating ability, 2) Bragg ptychography that enable imaging of targeted sub- volumes of a crystal. Both approaches will be discussed in the context of materials science problems that can be addressed in-situ at next-generation synchrotron storage rings including the Upgraded Advanced Photon Source project now underway at Argonne National Laboratory. Stephan Hruszkewycz is a staff scientist in the Materials Science Division at Argonne National Laboratory. His research focuses on developing and using coherent x-ray scattering techniques to interrogate nanoscale materials structure and dynamics under working conditions to reveal structure-property relationships. Currently he is using strain- sensitive coherent Bragg diffraction to image subtle strain fields in nanoscale crystals for photonic and quantum information applications. These research thrusts are pursued at high-brightness synchrotron sources with state-of-the-art coherence-preserving beamlines, including those at the Advanced Photon Source, NSLS-II, and LCLS, and aim to broaden the applicability of coherent diffraction imaging within both the broader materials science community. -

MEMOIRS Row Standing on the Stern, Venetian Style, from the Lido, Where I Lived, to the School in Venice, Where I Studied
BRUNO BENEDETTO ROSSI April 13, 1905–November 21, 1993 BY GEORGE W. CLARK The initial motivation of the experiment which led to this discovery [of Sco X-1] was a subconscious feeling for the inexhaustible wealth of nature, a wealth that goes far beyond the imagination of man. That feeling was possi- bly generated by experiences in my previous work on cosmic rays; more likely it was inborn and was the reason why, as a young man, I went into the field of cosmic rays. In any case, whenever technical progress opened a new window into the surrounding world, I felt the urge to look through this window, hoping to see something unexpected.1 BEGINNINGS RUNO ROSSI WAS BORN April 13, 1905, in Venice, the el- Bdest of three sons of Rino Rossi and Lina Minerbi. His father was an electrical engineer whose successful career began with work on the electrification of Venice. He wrote in his autobiography2 that his father loved science and would have chosen it for a career except for practical consider- ations. He attributes to his father the influence that turned what may have been an “inborn tendency toward science . into a lifelong commitment.” He recalled: perfectly clear winter mornings when the air was so unusually transparent that the Alps surrounding Venice became clearly visible and appeared in- credibly close (Fata Morgana if you are a child or a poet, anomalous atmo- spheric refraction if you are a scientist). On those mornings I would try to find a sandalo (a small gondola) and, accompanied by a friend, I would 3 4 BIOGRAPHICAL MEMOIRS row standing on the stern, Venetian style, from the Lido, where I lived, to the school in Venice, where I studied. -
