2016 Hillebrand Award to Dr. Stuart Licht

Greenhouse Gas Removal by its Transformation to Valuable Commodities

Stuart Licht, Department of Chemistry, George Washington University
Washington, DC, 20052, United States

As the levels of carbon dioxide increase in the Earth’s atmosphere, this greenhouse gas’s effects on climate change including species extinction, flooding, draught, famine and economic disruption become increasingly apparent. An incentive to remove CO2 is provided by a low energy, low cost, high yield conversion to valuable products such as carbon nanotubes. Displaying superior strength, conductivity, flexibility and durability, carbon nanotube (CNT) applications had been limited due to the cost intensive complexities of their synthesis. An inexpensive source of CNTs made from carbon dioxide will facilitate the rate of its adoption as an important societal resource for the building, aerospace, transportation, renewable energy, sporting and consumer electronics industries, while concurrently consuming carbon dioxide. We present an inexpensive, high-yield and scale-able synthesis of CNTs.

We show a new, unexpected chemistry for the effective capture of CO2 and its transformation at high yield and low energy, by dissolution in a molten carbonate electrolyte, and electrolysis splitting it to carbon nanotubes and oxygen.1-7 The CO2 reactant is directly absorbed from air (without the need for pre-concentration), or can be used and removed from industrial, home or transportation emissions.

We show that common metals act as CNT nucleation sites in molten media to efficiently drive the high yield electrolytic conversion of CO2 dissolved in molten carbonates to CNTs. We accomplish this by electrochemically reducing CO2 on steel electrodes in a molten carbonate electrolyte. The CNT structure is tuned by controlling the electrolysis conditions, such as the addition of trace common metals to act as CNF nucleation sites, the composition of the carbonate electrolyte, and the control of temperature and current density. Upward scalability of the process is demonstrated over several orders of magnitude.

The Licht group at GW University is in the midst of the semifinals of the Carbon XPrize (we are the C2CNF team at carbon.xprize.org), a global competition to demonstrate the most valuable product from the CO2 emissions of fossil fuel power plants. Our goal is to transform CO2 from a pollutant to a desired resource. Molten carbonate electrolysis production is significantly less expensive than contemporary CVD and polymer pulling methods to produce carbon nanotubes or nanofibers, and uses CO2 rather than organometallics or polymers as the reactant. An inexpensive source of CNTs has a large demand as a preferred, lighter weight, stronger replacements to metals and plastics, which (in addition to the battery, nanoelectronics and catalysis applications) can provide a large market to mitigate anthropogenic carbon dioxide.

2015 Hillebrand Award to Dr. Stephen A. Wise

Dr. Stephen A. Wise, Senior Analytical Chemist and Program Coordinator for Food and Nutrition within the Chemical Sciences Division of NIST, was presented the 2015 Hillebrand Prize by CSW past president, Alan Anderson. 

The selection of the recipient of the Hillebrnd prize, the highest award given by CSW, is difficult due to the fact that all nominees have an extensive record of publications and other research accomplishments in wide-ranging are as of the chemical sciences. This year’s recipient, Dr. Stephen A. Wise, of NIST has over 200 peer-reviewed publications and over 80 book chapters. Eight of his papers have been cited over 200 times and 18 over 100 times. This is a record not matched by many well-known analytical chemists. In addition to his outstanding publication record, Dr. Wise has helped shape his field as Chair of the Analytical Division of ACS, President of the International Society for Polycyclic Aromatic Hydrocarbons, Editor for Analytical and Bioanalytical Chemistry, Topical Editor for Analytical Separation Techniques for Polycyclic Aromatic Compounds, and service on the Editorial Board of Accreditation and Quality Assurance. Dr. Wise has received numerous awards in recognition of his scientific contribution. These include the 2001 Polycyclic Aromatic Hydrocarbon Research Award of the International Society of Polycyclic Aromatic Compounds (ISPAC), the 2006 Harvey W. Wiley Award from AOAC International, and the 2014 Reference Material Achievement Award from the Technical Division on Reference Materials of AOAC International. In 2013, he was selected as a Fellow of the American Chemical Society. For his achievements at NIST, he was recognized with the Department of Commerce Bronze Medal Award (1989) and Silver Medal Award (2008). Dr. Wise has made significant contributions to many aspects of analytical chemistry, including a landmark publication relating that the retention of polyaromatic hydrocarbons on reversed phase LC columns was correlated with the shape of the molecules.

Dr. Stephen A. Wise recently retired from the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland after 40 years of government service. He is currently a scientific consultant for the Office of Dietary Supplements at the National Institutes of Health (NIH-ODS) in Bethesda, Maryland. He received a B.A. in Chemistry from Weber State University and a Ph.D. in Analytical Chemistry from Arizona State University. He began his career at the National Bureau of Standards (NBS), now NIST, in 1976 as a research chemist involved in the development of liquid chromatographic methods for determination of trace organic constituents. Dr. Wise’s research efforts have focused on (1) development of chromato-graphic methods for the determination of organic contaminants (e.g., polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, and chlorinated pesticides) in environmental matrices such as sediment, tissue, and air particulate matter; (2) development of Standard Reference Materials (SRMs) for trace organic constituents in environmental, clinical, food, and dietary supplement matrices; (3) investigations of chromatographic separation mechanisms and chromatographic selectivity for PAHs and related compounds; and (4) development and implementation environmental specimen banking procedures. Throughout his career at NIST, Dr. Wise interacted extensively with other federal government agencies, including the Environmental Protection Agency (EPA),National Oceanic and Atmospheric Administration (NOAA), Centers for Disease Control and Prevention (CDC), and the National Institutes of Health (NIH), through interagency agreements to develop SRMs to support the regulatory needs of these government agencies. From 2002 until his retirement, he was responsible for managing a significant collaboration between NIST and NIH-ODS to develop analytical methods and reference materials for nutrients and/or active constituents in dietary supplements and for nutritional assessment markers in human serum and food.

2013 Hillebrand Award to Professor Michael Doyle

 Michael P. Doyle

Michael P. (Mike) Doyle is distinguished for his contributions to asymmetric catalysis and metal carbene transformations, for providing basic understanding to nitrosyl chemistry that includes the biochemical reactions of nitrites and nitrogen oxides, and for his research in physical organic chemistry and synthetic method development.  He began his research at Hope College in Michigan with nitrosyl chemistry, discovering the applications of nitrogen chemistry - from nitrosonium salts to nitrites – and providing the mechanistic details for modern understanding of the biological effects of nitrogen oxides and nitrosyls.

He is perhaps best known for his research in dirhodium-catalyzed reactions of diazo compounds and for his invention of the "Doyle catalysts" – dirhodium(II) tetracarboxamidates with chiral  lactam ligands that are commercially available (Doyle dirhodium catalyst, Rh2(5S-MEPY)4  (Sigma-Aldrich‎).  These catalysts have proven to provide the highest levels of stereocontrol in intramolecular cyclopropanation and carbon-hydrogen insertion reactions with diazoacetates of any catalyst ever developed for these chemical transformations. His research into metal carbene transformations of diazoacetates extended from addition reactions and insertion processes to ylide transformations and established the influence of ligands on reaction selectivities.  In addition to having a catalyst named after him, chemical transformations also carry his name, the best known of which is the "Doyle-Kirmse Reaction". The vast majority of this research was performed with undergraduate students since from 1968 until 1997 he was a faculty member at undergraduate institutions, and only in 2000 did he begin to take graduate students.

Since coming to the University of Maryland in 2003 Doyle has developed chiral dirhodium carboxamidates as exceptional catalysts for highly enantioselective Lewis acid promoted reactions, developed highly enantioselective [3+3]-cycloaddition reactions as an alternative to hetero-Diels-Alder reactions for the construction of heterocyclic compounds, established new oxidation methods and oxidation catalysts, and discovered novel paddle wheeled dirhodium structures.  His recent research on dirhodium caprolactamate catalyzed chemical oxidations with hydroperoxides has not only produced highly selective processes (allylic oxidation – the Umera-Doyle reaction - but he also clarified the mechanisms of these reactions from what had been a diverse array of interpretations.

Mike has been called the "guru of undergraduate research" (Rebecca Rawls, "An Undergraduate Champion", C&EN, Vol. 80, number 39, September 30, 2002, pg. 30-31) in recognition of his role in developing student careers in the chemical sciences through research and being an outspoken champion of research as an educational enterprise. More than 150 undergraduate students are coauthors of at least one publication with him, and there are several with five or more publications.  The list of his undergraduate coauthors constitutes a virtual who’s who in organic and inorganic academic chemistry today.  Postdoctoral associates who number fifty have been instrumental in his research endeavors with undergraduate students, and many of these associates are now faculty in academic institutions. He was one of the founders of the Council on Undergraduate Research (http://www.cur.org/), its first president (1978), and the Editor of its newsletter; and he was also the first Chairman (1987) for the Executive Committee of the National Conferences on Undergraduate Research (NCUR) that merged with CUR in 2011.  Doyle is the recipient of the 1995 James Flack Norris Award for Outstanding Achievements in the Teaching of Chemistry sponsored by the Northeastern Section of the American Chemical Society and the 2002 George C. Pimentel Award in Chemical Education from the American Chemical Society.

The involvements of Mike Doyle in the American Chemical Society and other professional organizations have been extensive. As Chair of the Department of Chemistry and Biochemistry at the University of Maryland, he led the department to national recognition for efforts in increasing diversity (see Lauren K. Wolf, "Blueprint for increasing Diversity", C&EN, Volume 89, issue 51, pg. 41-42, 2011).  Mike was General Chair for the 2011 Middle Atlantic Regional Meeting of the ACS during the same year that he was President of the Chemical Society of Washington; and he and his colleague, Andrei Vedernikov, chaired the Scientific Committee and organized the host site for the 2012 International Chemistry Olympiad.

Dirhodium, Dinitrogen, and Determined Influences from Talented Associates

The elements of a career in the chemical sciences are not only those whose combinations construct chemical compounds but also colleagues and students who shape the progress of what is yet to come.  This presentation will briefly trace the origin of current research through those who created the opportunity and focus on the development of asymmetric catalysis applied to the synthesis of many classes of organic compounds through metal carbene formation with dirhodium compounds.  The FDA increased the flow of research by their publication in 1992 of "The Development of New Stereoisomeric Drugs", and the NIH took up the challenge by focusing some of their resources on asymmetric synthesis with the beneficiaries being pharmaceutical companies and the general public who benefited from resulting advances.

From Fundamentals to New Tools and Back to Fundamentals

Abstract: In the past three decades, new insights into two physical phenomena, laser-solid interactions and electrosprays, reshaped the landscape of bioanalytical chemistry. Specific interactions of lasers with condensed matter are used throughout chemistry to synthesize, modify and probe materials of interest. Important examples include, matrix-assisted laser desorption ionization (MALDI) for biomolecular analysis, photonic ion production from nanostructures, and phase explosion for laser ablation sampling of biological specimens. Electrification of liquid menisci finds similarly diverse applications in macromolecular ion production, nanoencapsulation and electrospinning. Our efforts to understand the volatilization, ionization and fragmentation of biomolecules in these processes resulted in the description of limited energy transfer between matrix and analyte, and the introduction of a fluid dynamic model for MALDI. Analyte internal energy measurements in MALDI, electrospray ionization (ESI) and photonic ionization revealed fragmentation patterns in these highly complex processes. Columnar nanostructures, for example, silicon nanopost arrays (NAPA), were shown to exhibit photonic ion production, including the polarization dependence of ion yields. The formation and disintegration regimes of electrified liquid droplets were followed from bulk solution to nanoscopic droplets to explain ion production in ESI.

Armed with extensive knowledge about laser ablation sampling and various forms of ion production, we set out to design a new bioanalytical modality. This technique capitalized on mid-IR laser sampling of microvolumes followed by ESI of the ablation plume for mass spectrometric analysis. The resulting method, termed laser ablation electrospray ionization (LAESI), enabled the direct local analysis of biological tissues and cells, and their mass spectrometric imaging at atmospheric pressure in two and three dimensions. In situ LAESI measurements on numerous biomedical systems included plant tissues and cells, virally infected lymphocytes, energy harvesting microorganisms, rodent brain tissue sections and the central nervous system of molluscs. Optimized nanofabrication of NAPA resulted in an ultrasensitive ionization platform that enabled the metabolic analysis of a single yeast cell.

These novel tools enabled us to ask some fundamental questions that promised fresh insight in cell biology. Through the combination of cell dissection and LAESI mass spectrometry, we demonstrated the existence of significant metabolite gradients between the cytoplasm and the nucleus within a cell. Our ability to analyze individual cells on NAPA allowed the exploration of cellular heterogeneity and its changes under oxidative stress. In these endeavors we benefitted from an interdisciplinary approach that started with exploring the basic physics

Rewiring electrochemical power from start to finish via architectural design on the nanoscale

Abstract: Designing high-performance energy-storage devices that combine nanometric feature size with well-wired transport paths and that bridge to the macroscale requires an architectural perspective.  We use aerogel-like carbon nanofoam papers as our architectural test-bed because they provide a low cost and scalable nanocomposite that offers an optimal balance of critical architectural features:  (1) open, 3D interconnected macropores sized at 20-to-250 nm co-continuous with (2) ~20-nm pore walls of a size that reduces dead weight and volume yet retains mechanical strength and flexibility without compromising electronic conductivity.  Charge-storage or catalytic functionality can then be imparted to internal carbon walls simply by transporting reactants within the 3D “plumbing” of the macroporous foam.  Self-limiting modification strategies allow us to incorporate conformal, nanoscopic functional “paints” of metal(Mn, Ti, Ru, Fe)oxides or polymer (redox-active or electron insulating) or specifically adsorb metal nanoparticles (Pt, Au, Pd, Ag) throughout the macroscopic thickness (0.07 to 0.3 millimeter) of carbon nanofoam papers.  For instance, painting the carbon walls with 10-nm MnOx increases the mass-, geometric-, and volume-normalized capacitance (2- to 10-fold) relative to the native carbon nanofoam without significantly altering its high-rate character.  The oxide-modified paper is now a multifunctional electrode structure that can be used in an aqueous asymmetric electrochemical capacitor or as an air cathode in a Zn/air cell to electrocatalyze oxygen reduction and provide pulse power.  Our redesign of electrode structures using modified carbon nanofoam papers has catalyzed breakthroughs in our work within a broad range of multifunctional energy storage and conversion, including asymmetric electrochemical capacitors, air cathodes for metal–air batteries, 3-D batteries, and semifuel cells.

Exploring Sparsely-Populated States of Macromolecules by Diamagnetic and Paramagnetic NMR Relaxation

Abstract: Sparsely-populated states of macromolecules, characterized by short lifetimes and high free-energies relative to the predominant ground state, often play a key role in many biological, chemical and biophysical processes. We will summarize various new developments in paramagnetic NMR spectroscopy that permit these heretofore invisible, sparsely-populated states to be detected, characterized and visualized. In the fast exchange regime (time scale less than ~250-500 μs) the footprint of sparsely-populated states can be observed on paramagnetic relaxation enhancement profiles measured on the resonances of the major species, thereby yielding structural information that is directly related to paramagnetic center-nuclei distances, from which it is possible, under suitable circumstances, to compute a structure or ensemble of structures for the minor species.  This will be illustrated with regard to (a) the search process whereby transcription factors locate their specific DNA target site among a sea of non-specific sites, (b) the characterization of encounter complexes in protein-protein interactions; and (c) the visualization of large scale interdomain motions.

2009 Hillebrand Award to Dr. James E. Butler

Dr. James E. Butler
Gas/Surface Dynamics Section, Chemistry Division
Naval Research Laboratory, Washington, DC

The Chemical Society of Washington will present the 2009 Hillebrand Prize to Dr. James E. Butler, Head of the Gas/Surface Dynamics Section at the Naval Research Laboratory, at its dinner meeting on March 11, 2010. Dr. Butler will address the meeting with a seminar entitled "Alchemy."

Dr. Butler joined the Naval Research Laboratory in 1975 where he applied laser spectroscopy to the study of elementary reaction dynamics, photochemistry, and gas phase chemical kinetics relevant to atmospheric and combustion chemistries. Following a sabbatical year at the Institute of Molecular Science in Japan (1982-3), he used high resolution IR laser diode spectroscopy to the study of reactive transient molecules relevant to plasma processing and chemical vapor deposition (CVD). His work on the use of in situ laser diagnostics to the gaseous and surface processes in CVD initiated the field for reactive chemical modeling of CVD processes (1983-86). Beginning in 1987, Dr. Butler focused on the understanding of the growth chemistry and mechanisms of the newly reported CVD of diamond. In 1988, he formed the Gas/Surface Dynamics Section in the Surface Chemistry Branch of NRL to focus on the basic gaseous and surface chemical processes occurring in the CVD and plasma processing of materials relevant to modern advanced technologies. His current research interests lie primarily with understanding and exploiting the growth, characterization, properties, and applications of chemical vapor deposited (CVD) diamond materials.

Dr. Butler has been a visiting scientist at the National Research Council of Canada (1982), the Institute of Molecular Science in Japan (1982-3), the University of Witswatersrand in South Africa (1996), a Distinguished Lecturer in the Department on Mechanical Engineering at the University of Minnesota (1996), the Benjamin Meaker Visiting Professor of Physics and Chemistry at the University of Bristol in England (1997), the University of Melbourne in Australia (2006), and the University of Warwick in England (2007, 2009). Dr. Butler has published over 245 refereed journal papers (H factor of 45 as of January 2010), and given numerous plenary and invited technical presentations at professional society meetings, international conferences, and universities.

In addition to serving as technical advisor to ONR, SDIO, NSF, and DARPA on various diamond research initiatives, he has participated as an technical expert in a White House inquiry on controlling trade of ‘conflict' diamonds, served a consultant to various companies in the industrial diamond industry, chaired a Gordon Research Conference on Diamond, participated in the organization of numerous international conferences, and serves on the advisory board for the journal Gems and Gemology. He was presented with the Sigma Xi NRL Edison Chapter Applied Science Award in 2001 and the NRL Technology Transfer Award in 2009.

Abstract:  Alchemy is perceived by many as the art of turning "lead into gold", or more generally, something base (not valuable) into something valuable. In the last century, the science of chemistry has done exactly the same, converting base things such as sand into silicon wafers and ultimately the complex 'chips' that have enabled much of our modern technology. Thus 'Al Chemy', or 'the chemistry' is a way of describing the critical role of chemistry to modern society, just as ancient chemists and materials scientists may have used their knowledge to bring value to the market places of their times.

In this talk I will focus on a process, Chemical Vapor Deposition (CVD), which has become critical to the fabrication of many modern electronic materials and devices. The ‘Alchemy' I will describe is the growth of Diamond by CVD from as base a material as ‘sewer gas'. To understand the complexity of Diamond CVD requires knowledge of many processes: the decomposition of gaseous reactants, the fluid dynamics and transport of reactive species to the growing surface, the surface chemistry which in the case of diamond CVD, deposits diamond as opposed to graphitic or amorphous carbons, and the role of defects and impurities in the growth and quality of the diamond material. Thus Diamond CVD serves as an example of all the complex chemical and physical processes which occur during the CVD of materials, and provides an excellent platform for the development and testing of theoretical/computational tools since carbon has relatively few electrons and one can draw on the extensive knowledge base of organic and combustion chemistries. Diamond CVD has now enabled new technologies which exploit the extreme thermal, optical, mechanical, electronic, and chemical properties of diamond. CVD Diamonds provide the reproducible quality and morphology for technological applications, and a purity which can exceed that of the best natural diamonds.

2008 Hillebrand Award to Dr. Michael Kurylo

Dr. Michael Kurylo
Goddard Earth Sciences and Technology Center
University of Maryland Baltimore County
 
 
Dr. Michael J. Kurylo, senior research scientist at the Goddard Earth Sciences and Technology Center of the University of Maryland Baltimore County, will receive the 2008 Hillebrand Prize from the Chemical Society of Washington at its dinner meeting on March 12 at the NASA Goddard Recreation Center. Dr. Kurylo will address the meeting with a seminar entitled "From the Laboratory to the Stratosphere: Constructing a Bridge Between Science and Policy".

Dr. Kurylo received a B.S. degree in chemistry from Boston College in 1966 and a Ph.D. in physical chemistry from the Catholic University of America in 1969. Following a National Research Council Postdoctoral Associateship at the National Bureau of Standards (now NIST), he was a Research Chemist at NBS and NIST from 1971 – 2003. During the last half of this period, he continued his NIST research in laboratory atmospheric kinetics and photochemistry while serving on a detailed assignment to the National Aeronautics and Space Administration as manager of NASA’s Congressionally-mandated Upper Atmosphere Research Program. In 2004 he transferred to NASA as a Program Scientist in Atmospheric Composition, and retired from the federal government in 2008.

Dr. Kurylo’s laboratory research has focused on gas phase free radical photochemistry and kinetics with an emphasis on atmospheric processes related to stratospheric ozone depletion and climate change. An author or co-author of 140 scientific articles, he has given more than 190 technical presentations nationally and internationally. As a NASA program scientist he was largely responsible for organizing and implementing several airborne scientific investigations that linked the depletion of stratospheric ozone to manmade chemicals containing chlorine and bromine. He has provided similar leadership for other field investigations utilizing measurements from satellites, aircraft, balloons, and the ground for examining the connections between changes in atmospheric composition and in climate. Since 1987, he has served at the interface between scientific research and international environmental policy through extensive participation in each of the Scientific Assessments of Ozone Depletion conducted by the United Nations Environment Programme and the World Meteorological Organization. These assessments are required by the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer and the Vienna Convention for the Protection of the Ozone Layer. He has been elected Chair of several past meetings of international Ozone Research Managers of the Parties to the Vienna Convention and has presented the consensus recommendations at subsequent meetings of the Parties (most recently in Doha, Qatar this past November). Dr. Kurylo also holds leadership positions on several international organizations in atmospheric chemistry.

As an internationally acclaimed atmospheric research scientist and program manager, Dr. Kurylo has received numerous awards. These include the Department of Commerce Bronze and Silver Medals, two NASA Exceptional Service Medals, the NASA Cooperative External Achievement Award, more than a dozen NASA Group Achievement Awards, the Catholic University of America Alumni Achievement Award in the Field of Science, the National Oceanic and Atmospheric Administration Environmental Hero Award, and the US Environmental Protection Agency Stratospheric Ozone Protection Award. His efforts leading to the success of the Montreal Protocol have recently been acknowledged by his being named to the Montreal Protocol Who’s Who listing. Dr. Kurylo is a member of the ACS, the American Physical Society, the American Geophysical Union, and Sigma Xi.

At the CSW dinner meeting seminar, Dr. Kurylo will describe developments in laboratory measurement techniques for gas phase kinetics and photochemistry that have enabled atmospheric scientists to isolate and investigate specific chemical reactions. These studies have provided the data required for modeling calculations of the transformations of important atmospheric trace species. The role of measurement campaigns for studying the atmosphere itself as a complex photochemical reactor will also be described.

Dr. Kurylo will also provide an historical perspective of the development of past and present national and international research programs for investigating changes in atmospheric composition. Scientific achievement under these programs have led to the success of the Montreal Protocol on Substances that Deplete the Ozone Layer.

Abstract: Depletion of the Earth’s stratospheric ozone layer was the first manifestation of global environmental change attributable to human activity. Ranging from moderate losses at mid-latitudes to large-scale seasonal losses in the Polar Regions, its detection and attribution have required integrated efforts across the full spectrum of atmospheric science. Sophisticated atmospheric observations from the ground, balloons, aircraft, and satellites together with the results from laboratory investigations have provided the scientific bases for sound environmental policy at the national and international levels. Dr. Kurylo will describe the developments in laboratory measurement techniques for gas phase kinetics and photochemistry that have enabled atmospheric scientists to isolate and investigate specific chemical reactions. The role of measurement campaigns for studying the atmosphere itself as a complex photochemical reactor will also be described. The subsequent interpretation of the field measurement observations through the use of laboratory data has been a key element in the formulation of international assessments that underlie environmental treaties.
