[Eastern Kentucky University]

Today is October 17, 2018
Our next speaker will be Elizabeth Cottrell from Smithsonian Institution speaking about
"Breathing the Earth"
on October 19, 2018 in Cargill Planetarium.

Abstract - When you hear the word “volcano,” what comes to your mind? Volcanoes are windows to Earth’s deep interior, revealing to us what lies beyond depths accessible to human exploration. Volcanoes shape the landscape, the hydrosphere, and human civilization. From natural disasters to climate change and from diamonds to Dr. Evil, we will explore volcano mysteries together.

Although synthetic polymers are indispensable in a diverse array of applications, ranging from commodity packaging and structural materials to technologically complex biomedical and electronic devices, their synthesis and disposal pose important environmental challenges. The focus of our research is the development of sustainable routes to polymers that have reduced environmental impact. This lecture will focus on our research to transition from fossil fuels to renewable resources for polymer synthesis, as well as the development of polymeric materials designed to bring positive benefits to the environment.

  • George M Whitesides, Professor of Chemistry, Harvard University, "Roderick Seminar 2018 - Soft Robotics", March 26, 2018  modify info
    Abstract - "Robotics" is a field with broad interest: it combines mechanical engineering, information science, and animal physiology with manufacturing, workforce development, economics, and other areas. The most highly developed classes of robots have been build based on conceptual models provided by the body-plans of animals with skeletons (humans, horses), and have made it possible to carry out tasks that humans and animals could not (for a variety of reasons). We are interested in robots based a different, simpler class of organisms (invertebrates: starfish, worms, octopi). Because these organisms, and the robots having designs stimulated by them, have no skeletons, they provide enormous opportunities in materials and polymer science, rather than primarily in mechanical engineering. This seminar will outline one approach to soft robots, and suggest problems and opportunities in this new field.
  • George Whitesides, Professor of Chemistry, Harvard University, "Reengineering Chemistry", March 26, 2018  modify info

  • Malcolm Forbes, Professor of Chemistry, Bowling Green State University, "Not So Free Radicals", February 1, 2018  modify info
    Abstract - In this lecture I will give an overview of time-resolved and steady–state electron paramagnetic resonance (TREPR and SSEPR) spectroscopies describe and their application in the study of radical structure, dynamics, and reactivity. I will emphasize the use of these techniques in probing chemical systems experiencing restricted translational or rotational motion. Examples of such systems include polymer coatings, structured fluids, microbubbles, nanocrystals, reverse micelles, and vesicles. The TREPR technique is useful because it detects the primary photochemical events rather than rearrangements or secondary photolysis products. Examining radicals on the sub-microsecond time scale also allows us to examine the interplay between spin wave function evolution and diffusion in confined spaces (“spin chemistry”). In the second part of my talk I will demonstrate use of TREPR and SSEPR in polymer degradation chemistry, the topology of singlet oxygen production in heterogeneous structures such as vesicles and micelles, the photochemical “skunking” of beer by sunlight, biocompatible photopolymerization reactions, and the photoreactivity of sunless tanning lotions. Finally, I will present a brief history and overview of the Center for Pure & Applied Photosciences at BGSU, highlighting our faculty, recent research results, and our facilities.
  • Johnathan N. Brantley, Assistant Professor of Chemistry, University of Tennessee at Knoxville, "Unmasking Latent Reactivity though Materials and Methods", September 19, 2017  modify info
    Abstract - The interplay between macroscopic forces and chemical reactivity has attracted significant interest, given the potential to harness this surprising phenomenon for an array of applications in materials science and synthetic methodology. Polymer mechanochemistry, wherein exogenous forces drive chemistry within polymeric matrices, has emerged at the forefront of efforts directed toward harnessing stress to access new reactivity modes. Through the combination of experiment and theory, our efforts have unveiled fundamental insights that hold promise for multifarious applications. Salient examples include mechanical cycloreversions of 1,2,3-triazoles, as well as the suppression of certain dissociative reactions under strain. Moreover, concepts from these systems could be applied to rationally design biological molecules with predictable responses to force. Moving beyond a macromolecular focus, we have explored strategies for isolating reactive intermediates in trifluoromethylative processes and probing their innate chemistry. Taken together, this work suggests exciting directions for unlocking hidden reactivity to access new chemical space.

  • Bob Howell, Professor of Chemistry, Central Michigan University, "Nontoxic Phosphorus Flame Retardants from Renewable Biosources", March 2, 2017  modify info
    Abstract - Polymeric materials are pervasive in modern society and are largely responsible for the high standard of living enjoyed by citizens of much of the world. For most applications, polymeric materials must be flame retarded. Traditionally, organohalogen compounds, particularly brominated aromatics, have been prominent flame retardants. However, these materials are stable in the environment, tend to bioaccumulate, and may pose a risk to human health. Replacements are needed. Organophosphorus compounds offer the greatest potential to fill this need. They are readily available from synthesis and are generally less toxic than their organohalogen counterparts. In particular, effective organophosphorus compounds derived from renewable biosources offer the potential for low toxicity. In addition, they are independent of price fluctuations in the petrochemical markets. A variety of phosphorus compounds based on annually-renewable biosources (starch, plant oils, tartaric acid, chitosan) have been prepared and shown to provide good flame retardancy in DGEBA epoxy resin using standard small scale tests [limiting oxygen index (LOI), UL 94 vertical burn, microcalorimetry (mcc)].
  • Ampofo Darko, Assistant Professor, University of Tennessee at Knoxville, "Principles of Strain in Synthesis and Catalysis", January 10, 2017  modify info
    Abstract - The concept of strain, as discussed in terms of bond length, bond angle, and torsional distortions, has been an invaluable tool for organic chemists. Strain energies provide a way to examine compounds of unusual geometries and also offer an explanation of the driving force for certain reactions. The ability to harness the energy of strained compounds has resulted in very rapid reactions with numerous applications. Specifically discussed in this talk is ongoing work implementing the concept of strain in the design of ligands for rhodium complexes as catalysts in metal-carbenoid reactions.
  • Neil Ayres, Associate Professor, University of Cincinnati, "Heparin inspired polymers for blood-contacting biomaterials at 11 AM in room 101", September 24, 2015  modify info
    Abstract - Biomaterials interface with biological systems to improve or treat these systems. The biocompatibility and performance of a biomaterial is dependent on the chemistry of the material. In our work we have focused on polymer blood-compatibility. Our primary goal has been to prepare synthetic polyureas that can mimic the function of heparin, a naturally occurring anticoagulant polysaccharide. This presentation will detail our progress in this area including the synthesis methodology we have developed, and our investigations into various structure property relationships. These relationships include the identity of pendant sugars on the polyurea and the isocyanates used to make the polymer. Recent work looking at shape memory properties will also be included. Neil Ayres received his Ph. D. in chemistry from the University of Warwick in 2003 where he worked for Prof. David Haddleton investigating surface initiated atom transfer radical polymerization (ATRP). After working as a post doc at the University of Southern Mississippi, the University of Akron, and the University of Utah, he became a professor in the department of chemistry at the University of Cincinnati in 2008. He received tenure and promotion to Associate Professor in 2014 and currently has research interests in synthetic chemistry of biomaterials and controlled polymerizations.

  • Katie Salmeron, Graduate Student, University of Kentucky, "INVESTIGATIONS OF INTERLEUKIN-1 ALPHA AS A NOVEL STROKE THERAPY IN EXPERIMENTAL ISCHEMIC STROKE", February 15, 2018  modify info
    Abstract - Stroke is a leading cause of death and disability worldwide. Although rapid recognition and prompt treatment have dropped mortality rates, most stroke survivors are left with permanent disability. Approximately 87% of all strokes result from the occlusion of cerebrovasculature (ischemic strokes). Potential stroke therapeutics have included anti-inflammatory drugs, as well as many other targets with the goal of mitigating the acute and chronic inflammatory responses typically seen in an ischemic stroke. While these approaches have had great success in preclinical studies, their clinical translation has been less successful. Master inflammatory cytokines, such as IL-1, are of particular interest. IL-1's isoforms, IL-1 and IL-1 , were long thought to have similar function. While IL-1 has been extensively studied in stroke, the role of IL-1 during post stroke inflammation has been overlooked. Because IL-1 inhibitors have been unsuccessful in clinical application, we reasoned that IL-1 may provide previously unknown benefits to the brain after injury. We hypothesized that IL-1 could be protective or even accelerate reparative processes in the brain such as producing new blood vessels (angiogenesis) or neurons (neurogenesis). To test that IL-1 is protective after stroke, we tested IL-1 's protective effects on primary cortical neurons in in vitro models of stroke. We showed that IL-1 was directly protective on primary cortical neurons in a dose-dependent fashion. We then performed mouse middle cerebral artery occlusion stroke studies to determine the safety and of giving IL-1 in vivo. These studies showed that administering IL-1 acutely was neuroprotective. However, intravenous (IV) administration of IL-1 resulted in transient, hemodynamic changes following drug delivery. To minimize these systemic effects, we administered IL-1 intra-arterially (IA) directly into the stroke affected brain tissue, allowing us to significantly lower the concentration of administered IL-1 . In comparison to IV, IA IL-1 showed greater histological protection from ischemic injury as well as improved functional recovery following stroke, all without systemic side effects. To test that IL-1 could aid in neurorepair following stroke, we tested IL-1 's ability to help damaged blood vessels repair in vitro. We found that IL-1 significantly increased brain endothelial cell activation, proliferation, migration, and capillary formation. We tested IL-1 's proangiogenic properties in vivo by administering IL-1 three days following stroke. Delayed administration allowed us to separate IL-1 's acute neuroprotective effects from potential subacute angiogenic effects. We found that mice receiving IL-1 performed significantly better on behavioral tests and also showed greater vascularization within the penumbra two weeks following stroke. We also found that IL-1 treated animals showed more endothelial activation than vehicle treated animals. Finally, our studies showed that IL-1 treated animals showed increased early-phase neurogenesis with evidence of increased proliferation at the subventricular zone suggesting that IL-1 's beneficial effects are even more far-reaching than previously thought. In conclusion, our experiments suggest that the inflammatory cytokine IL-1 is neuroprotective and neuroreparative in experimental ischemic stroke and worthy of further study as a novel stroke therapy.

    Abstract - Fibrinogen is the most abundant protein involved in blood coagulation and has been implicated in cardiovascular disease. During the formation of a blood clot, thrombin cleaves fibrinopeptides A and B from fibrinogen (AαBβγ)2 to form fibrin monomers (αβγ)2. Fibrin polymerization proceeds with the formation of protofibrils and a hard clot is only generated when the transglutaminase factor XIII (FXIII) introduces covalent γ- glutamyl-ε-lysyl bonds between specific reactive glutamines and lysines in the fibrin clot network. The αC region (Aα221-610) of fibrinogen contains numerous reactive glutamines in the flexible αC-connector (221-392) and a FXIII binding site within αC (371-425). MALDI-TOF mass spectrometry assays and 2D 15N-1H HSQC NMR studies have been carried out on fibrinogen αC (233-425), a segment containing three known reactive glutamines (Q237, Q328, and Q366). FXIIIa crosslinks these three glutamines to the lysine mimic glycine ethyl ester (GEE) in the order Q237 >> Q366 > Q328. To better characterize this system, single site mutants have been generated in which the reactive glutamines (Q) are individually replaced with inactive asparagines (N). Work with these mutants suggests that FXIIIa does not require crosslinking to occur in a sequential manner. Each glutamine can be cross-linked independently of the other. Due to its highly flexible nature, the fibrinogen αC region has not been observed by X-ray crystallography. 2D HSQC NMR studies on 15N-labeled αC (233-425) have now confirmed that this protein is intrinsically disordered. FXIIIa substrate specificity for specific reactive glutamines is predicted to be controlled by a combination of neighboring residues and the presence of regions of disorder. The knowledge gained from these studies can be used for subsequent assay and drug designs.

    Abstract - Metabolomics is the detection and identification of metabolites from any given biological system and is routinely applied as a tool for system biology research. Innovations in analytical technique and advances in bioinformatics ensured that now metabolomics can help us understand systems-level effects in many complex biological studies, including those focusing on cancer, inflammatory diseases, and gut microbiota studies. Among the available metabolomics techniques, mass spectrometry (MS)-based metabolomics offers an excellent combination of sensitivity and selectivity, and can be used for high-throughput metabolite analysis. This talk will focus on both the development and applications of novel mass spectrometry based metabolomics. We will introduce a couple of innovative MS-based methods that can be used for multiplex metabolites analysis, as well as give several successful examples of their applications in biomedical studies.

    Abstract - Where do new stars form in our Milky Way Galaxy? Where do they form in the neighboring Andromeda Galaxy? Observations of both galaxies at different electromagnetic wavelengths (radio, infrared, visible light and ultraviolet) yield the answer. Historically, astronomers relied upon studies of visible light. Today, they have access to the full range of electromagnetic radiation from the universe. Images of our Milky Way Galaxy and of the Andromeda Galaxy at different wavelengths reveal much about the structure of these galaxies and the locales within them where the next generation of stars is forming.

    Abstract - Milliseconds after the Big Bang the entire universe was filled with the most perfect liquid known to humanity- the Quark Gluon Plasma. The Quark Gluon Plasma has a number of peculiar properties, for instance, it flows like a liquid where friction effects are surprisingly small and it still maintains liquid-like properties on scales as small as the size of the nucleus of an atom. Because of the expansion and cooling of the Early Universe, the primordial Quark Gluon Plasma was extremely short lived and most of its signatures were washed away as the entire universe bloomed into existence. Over the past 15 years, collider experiments have been smashing heavy-ions together at 99.9999% the speed of light in order to produce a tiny droplet of the Quark Gluon Plasma with a radius of ~ trillionth cm. The collisions reach temperatures as high as a few trillion Kelvin which are able to "melt" ions into a dense "soup" of quarks and gluons that are constantly interacting with each other. In this seminar, the motion of this "quark gluon soup" is recreated using state-of-the-art numerical simulations that describe an almost perfect liquid moving at nearly the speed of light on high performance computers.

    Abstract - Nuclei are melted in high energy collisions at the Large Hadron Collider at CERN, forming a phase of matter called the Quark Gluon Plasma. This phase of matter existed shortly after the Big Bang. As it expands and cools, it refreezes, forming particles called hadrons. We determine the properties of the Quark Gluon Plasma by studying these hadrons. I will discuss how we can figure out what the properties of this Quark Gluon Plasma are by studying these hadrons. I will also talk about what it is like to be a part of a large international experiment.

    Abstract - The Standard Model of particle interactions, successful though it is, leaves many questions unanswered. Notably, it does not address the nature of dark matter, nor can it explain the observed cosmic surplus of matter over antimatter. The most popular models of "new physics" have been those that address these questions, by tying them to the theoretical origin of the weak interactions. However, with the Higgs discovery at the LHC and the non-observation of any other new effects, such enlargements of the Standard Model are becoming increasingly constrained. It is possible, rather, that essential clues as to its nature may first come from the appearance of light, weakly coupled new physics, which would not appear in LHC measurements, but to which low-energy, precision tests of the Standard Model are exquisitely sensitive. In this context, I will discuss an experimental anomaly in Be-8 nuclear transitions that may be interpreted as evidence for a new, weak force of some 12 fm in range. I will review the experimental evidence, its interpretation and implications, and emphasize what further experimental tests can be done to probe the experimental anomaly and its interpretation.

    Abstract - One of the outstanding questions in volcanology is why the interaction between water and magma/lava sometimes leads to passive interactions, like the formation of pillow lava along the coast of Hawaii, and sometimes leads to violent explosions, and the production of dangerous ash and flying debris. Volcanic deposits produced by both processes provide information on the millimeter to decimeter scale interactions. Satellite imagery enables the remote observation of the deposits and landforms produced by eruptions on the hundreds to thousands of meters scale. Experiments provide an opportunity to evaluate the conditions that lead to these eruptions at the time scale of individual explosions. The incorporation of these three datasets is necessary to unravel these events and enable the evaluation of future hazards at volcanoes around the world.

    Abstract - Convergent plate boundaries, where one tectonic plate dives under the other plate, such as modern Indian-Asian convergent boundary forming the Himalayas, are the locus of mountain building processes (orogenesis) on planet Earth. During the growth of an orogen, the outermost layer of Earth, continental crust, gets thicker owing to tectonic shortening and mantle-derived magma. Eventually, these systems reach a critical point where mountains cannot continue to grow vertically and horizontally and start to collapse under its own weight (orogenic collapse), which signifies the end of mountain building processes. During the collapse, mid-lower crustal rocks (>10 km) exhume rapidly to the surface along large fault zones. In this presentation, I will give examples from the North American Cordillera and the Adirondack Mountains, where we applied multiple dating techniques (geochronology) to provide better constraints on the formation and evolution of these mountains and to shed light on what mid-crustal rocks record during a planetary scale mountain-building events.

    Abstract - The Earth’s crust is divided into tectonic plates—large regions of oceanic and continental rock that shift relative to one another, pushing continents apart or bringing them together. When two plates move apart, new ocean floor is formed between them, as part of a volcanic process that produces a type of lava called basalt. At these plate boundaries, the solid residue of this magma production may also be exposed. These rocks, called peridotite, offer rare opportunities to study the material that makes up the Earth’s interior. In this talk, I will discuss the geochemistry of a suite of both peridotite and basalt rock samples dredged from the floor of the Southwestern Indian Ocean. In particular, I will demonstrate how the thermodynamic property of oxygen fugacity can provide insight into volcanic processes that initiate deep in the Earth’s upper mantle. I will show that, although the thermal history of peridotites must be carefully accounted for, both rock types ultimately give consistent information about the Earth’s interior. Finally, I will discuss both the implications of these results for important outstanding geologic questions, such as why the Earth has continents, as well as future research directions involving a range of geologic instrumentation.

    Abstract - Throughout Earth’s crust, fluids are the principal agents in transporting and localizing the Earth’s energy and mineral resources. Furthermore, the genesis and evolution of many different kinds of rocks are influenced by the flux of fluids which act as both reaction media and reactants. Among the many different types of crustal fluids, those containing volatile carbon, hydrogen and oxygen (C-H-O) species tend to dominate, and they commonly contain hydrocarbons such as methane as both a major constituent and an important energy source, particularly in sedimentary basins. Industry exploration and exploitation of shale gas (e.g. Marcellus, Utica, Barnett formations) have refocused attention on understanding the fundamental behavior of volatile hydrocarbon – brine – rock interactions. Interestingly, recent observations of hydrocarbons emanating from non-sedimentary systems (abiogenic), such as mid-ocean ridge hydrothermal systems or occurring within some crystalline rock-dominated Precambrian Shield environments have challenged the view that organic rich sediments provide the only significant source of crustal hydrocarbons. Hydrocarbons and associated aqueous solutions and other volatile species such as CO2 can occupy the pores or fractures of numerous types of complex heterogeneous earth materials present in the systems outlined above. This accessible porosity within rocks can span wide length scales (d as pore diameter or fracture aperture) including micro-, meso-, and macroporous regimes (d < 20 Å, 20 < d < 500 Å, and d > 500 Å, respectively, as defined by IUPAC). Porous solid matrices include rock or soil systems that contain clays and other phyllosilicates, zeolites, coal, graphite, or other carbonaceous-rich units; and weathered or altered silicates, oxides, and carbonates. A number of factors dictate how fluids, and with them reactants and products of intrapore transformations, migrate into and through these nano-environments, wet, and ultimately adsorb and react with the solid surfaces. These include the size, shape, distribution, and connectivity of these confined geometries, the chemistry of the solid, the chemistry of the fluids, and their physical properties. The dynamic behavior of fluids and gases contained within solids is controlled by processes occurring at the interface between the various phases (e.g., water-water, water-solute, water- volatile, water-solid, solute-solid, volatile-solid, etc.), as well as the rates of supply and removal of mobile constituents. The richness and complexity of rock-fluid interactions especially those involving nano-confined geometries only underscores the need to adopt a multidisciplinary approach when trying to quantify this behavior regardless of the C-H-O fluid type or the nature of the porous matrix. This presentation will touch upon some key examples of novel experimental and analytical techniques used in concert with state-of-the-art theory, modeling and simulation approaches to address these issues. In the Cole group at OSU there is a special emphasis on building synergistic links among results obtained from various advanced microscopy, neutron scattering and NMR studies which are integrated into our research portfolio with molecular dynamics modeling, to provide new phenomenological insights. The long-range goal of our research is to quantitatively link structure, dynamics and reactivity in complex mineral/C-H-O systems from the atomic to the molecular to the macroscopic levels, leading to predictive understanding of the consequences of fluid- rock interactions over the large time and length scales relevant to important geoscience ‘compartments’ such as deep sedimentary basins, tight shale, gas shale, continental and oceanic hydrothermal systems and formations targeted for CO2 storage.
