Biography

Professor Anagnostopoulos received his B.Sc. in Chemistry from University of Patras and M.Sc. in Environmental Analysis and Ph.D. in Radiochemistry in 2010 and 2012, respectively, from the same institution. He conducted his postdoctoral studies at Florida International University in Miami in projects funded by Department of Energy – Office of Environmental Management. He is currently Assistant Professor at the Department of Chemistry at the University of Central Florida, where he leads the Radiochemistry program. The University of Central Florida is the largest institution in enrollment in the U.S. (~68000 students) and official partner of NASA (located a short drive from NASA’s facilities at Cape Canaveral, Florida). His group's research focuses on environmental radiochemistry, nuclear fuel disposal and design of materials for radionuclide retardation, as well as nuclear forensics. His research portfolio includes projects funded by the U.S. Department of Energy, the U.S. Nuclear Regulatory Commission and he is part of the University -  National Nuclear Security Agency consortium.

Abstract

In the United States, there are several sites that are contaminated with radionuclides, legacy of nuclear operations of the Manhattan project during Cold War. These sites are managed by the U.S. Department of Energy and the remediation operations are currently the largest environmental cleanup program in the world. This presentation will provide a brief overview of the legacy contamination and the diverse challenges that come with it from a scientific (e.g. environmental and analytical) point of view, as well as regulatory standpoint. Specifically, it will focus on the studies of the Anagnostopoulos Research Group in interface redox chemistry and how it affects radionuclide fate in the environment and the development of analytical tools for accurate radionuclide speciation in the environment at trace levels. Emphasis will be given to the geochemistry of natural strong oxidizing agents such as manganese oxides and aqueous complexes, that influence the stability of any redox sensitive metal and metalloid reduced species, such as technetium (Tc-99), radioiodine (I-129) and uranium, all major risk driving contaminants across the Department of Energy Nuclear Legacy Sites complex. All these entities can change redox state depending on the environmental conditions and interactions with natural substrates resulting in more mobile species, which pose a larger threat to the biosphere.

Ανακοινώνεται ότι ο Dr Devis Di Tommaso

θα δώσει μια ομιλία την Πέμπτη 12 Μαϊου 2022, 1-2 μμ με θέμα:

"Solution additives promoting the onset of MgCO3"

Abstract: I will report recent work on identifying solution composition conditions that could promote the low-temperature

CO2 conversion into magnesite (MgCO3). Formed via aqueous carbonation of Mg2+ ions, the crystallization of magnesite is a promising route to carbon capture and reuse, albeit limited by the slow precipitation of MgCO3. Although magnesite is naturally abundant, forming at low-temperature conditions, its industrial production is an energy-intensive process due to the temperatures required to prevent the formation of hydrated phases. The principal difficulty arises from the very strong Mg2+···H2O interaction, raising barriers to Mg-dehydration. We have used atomistic simulations, complemented by spectroscopic experiments, to investigate the influence of solution additives, ranging from simple halides to more complex molecules, on the early stages of aqueous MgCO3

formation: Mg2+ dehydration; pre-nucleation Mg2+∙∙∙CO32– pairing.

Simulations of hydrated Mg2+, in the absence and presence of several solution additive anions, show that in pure water the metal aquo metal complex, Mg(H2O)62+, is the only stable coordination state; yet anions may stabilise undercoordinated five-hydration configurations. Solution composition can lower the barrier to Mg2+ dehydration and subsequent incorporation into the lattice of Mg-carbonates, promoting low-temperature crystallisation. Through a fundamental understanding of the role of solution additives in the mechanism of Mg2+ dehydration, our results help rationalise previously reported experimental observation of the effect of solvation environments on the growth of magnesite. Towards the end of my presentation, I will report the design a carbonation rig to perform real time, in-situ neutron measurements of CO2 mineralization at the Rutherford Appleton Laboratory.

Bio

Devis was born and raised in Italy. He studied Chemistry at the Universita' degli Studi di Trieste and graduated summa cum laude in 2002. He carried out his doctoral studies in the Theoretical Chemistry group headed by Professor Piero Decleva and, in 2006, he successfully defended the Ph.D. thesis with a work on the application and development of density functional theory methods for the study of molecular photoionization processes.

In 2006, Devis conducted postdoctoral research at the Royal Institution of Great Britain in the group of Professor Richard Catlow, where his work focused on theoretical catalysis.

As part of a Marie-Curie research and training network, in 2007 he moved to University College London in the group of Professor Nora de Leeuw to work on the development and application of computer simulation methods to investigate the nucleation and growth of metal carbonates from solution. In January 2012 he was awarded a Royal Society Industry Fellowship.

Devis joined the School of Biological and Chemical Sciences at Queen Mary in September 2013. He was promoted to Senior Lecturer (Associate Professor) in 2020.

He currently leads an EU-funded consortium, FUNMIN, to accelerate the process of CO2 mineralization from solution.

Biography

Ariel L. Furst received a B.S. degree in Chemistry from the University of Chicago. She then completed her Ph.D. in the lab of Prof. Jacqueline K. Barton at the California Institute of Technology developing new cancer diagnostic strategies based on DNA charge transport. She was an A. O. Beckman Postdoctoral Fellow in the lab of Prof. Matthew Francis at UC, Berkeley developing sensors to monitor environmental pollutants. Currently, her lab combines biological, chemical, and materials engineering to solve challenges in human health and environmental sustainability. She is passionate about STEM outreach and increasing participation of underrepresented groups in engineering.

Abstract

Electrochemistry is an exceptionally powerful tool to monitor chemical and biological interactions. By harnessing the inherent activity and function of biomolecules, we have significantly improved the selectivity and sensitivity of electrochemical biosensors. Specifically, by combining electrochemistry with synthetic biology, we have developed a platform to detect biologically-active small-molecule environmental pollutants at sub-micromolar levels. Similarly, by harnessing the inherent metabolic activity of pathogens, we can detect bacteria that cause food- and water-borne illnesses. By combining improved chemistries for biomolecule modification with unique signal amplification strategies, we have successfully detected targets from extremely complex solutions and directly incorporated remediation with detection.

Short cv: Liliana Schaefer, MD, is a Professor of Pharmacology at the Institute of Pharmacology and Toxicology, Goethe University in Frankfurt, Germany and Adjunct Research Professor of Pathology, Anatomy and Cell Biology, Thomas Jefferson University, Philadelphia, USA. Dr. Schaefer has made significant contributions to the field of proteoglycans by discovering that two components of the extracellular matrix, Decorin and Biglycan, act as endogenous danger signals. Currently Dr. Schaefer is the President of the Histochemical Society, the Editor-in-Chief of the American Journal of Physiology-Cell Physiology, the member of the FASEB publication committee, and the Chair of the Gordon Research Conference on Proteoglycans 2022.

Short talk description: It is well established that biglycan, a small leucine-rich proteoglycan, acts as an extracellular matrix-derived danger signal in its soluble form. By binding to innate immunity Toll-like receptors (TLR) 2 and 4, biglycan initiates and perpetuates the inflammatory response. Previous work has conveyed that biglycan's role in inflammation extends far beyond its function as a canonical danger signal. Mounting evidence suggests that the selective interactions between biglycan, TLRs, and their adapter proteins critically regulate downstream signaling and disease outcome. Biglycan can act as a high-affinity ligand for TLR coreceptors CD14 and CD44, further providing an additional layer of complexity. We propose a novel concept, that biglycan steers signaling toward inflammation by interacting with CD14, whereas it can trigger autophagy by binding to CD44. Thus, biglycan, and perhaps others soluble proteoglycans, could function as molecular switches which could either propagate the signaling of chronic inflammation or promote the resolution of inflammatory processes.

Short talk description: Heparanase (HPSE) has been defined as a multitasking protein that exhibits a peculiar enzymatic activity towards HS chains but which simultaneously performs other non-enzymatic functions. Through its enzymatic activity, HPSE catalyzes the cutting of the side chains of heparan sulfate (HS) proteoglycans, thus contributing to the remodeling of the extracellular matrix and of the basal membranes. Furthermore, thanks to this activity, HPSE also promotes the release and diffusion of various HS-linked molecules like growth factors, cytokines and enzymes. In addition to being an enzyme, HPSE has been shown to possess the ability to trigger different signaling pathways by interacting with transmembrane proteins. In normal tissue and in physiological conditions, HPSE exhibits only low levels of expression restricted only to keratinocytes, trophoblast, platelets and mast cells and leukocytes. On the contrary, in pathological conditions, such as in tumor progression and metastasis, inflammation and fibrosis, it is overexpressed. With this talk , we intend to provide an update on the current knowledge about the different role of HPSE during tumor progression and fibrosis.

Short cv: Prof. Onisto graduated from the Biological Sciences at the University of Padova in 1985. During 1988-1992 he worked as a Ph.D. candidate in molecular and cellular biology and pathology at University of Padova. In 1992 became Assistant Professor at the Institute of Histology and Embryology (from 2000 at the Dept.of Biomedical Sciences), School of Medicine of the University of Padova and Associate Professor in 2016.  His current research deals with the study of heparanase, the unique and specific endoglycosidase capable of cleaving heparan sulfate (HS) chains. HS cleavage results in remodelling of ECM as well as in regulating the release of many HS-linked molecules such as growth factors, cytokines and enzymes involved in inflammation, wound healing and tumour invasion. Dr. M. Onisto research activity has resulted in 89 publications (83 papers on international journals surveyed by ISI and 6 book chapters)

 Περίληψη

The spread of misinformation online is a global problem that requires global solutions. To that end, we conducted an experiment in 16 countries across 6 continents (N = 33,480) to investigate predictors of susceptibility to misinformation and interventions to combat misinformation. In every country, participants with a more analytic cognitive style and stronger accuracy-related motivations were better at discerning truth from falsehood; valuing democracy was also associated with greater truth discernment whereas political conservatism was negatively associated with truth discernment in most countries. Subtly prompting people to think about accuracy was broadly effective at improving the veracity of news that people were willing to share, as were minimal digital literacy tips. Finally, crowdsourced accuracy evaluation was able to differentiate true from false headlines with high accuracy in all countries. The consistent patterns we observe suggest that the psychological factors underlying the misinformation challenge are similar across the globe, and that similar solutions may be broadly effective.
