SUMMARY:Photonics Seminar: Paulo Ferreira\, International Iberian Nanotechnology Laboratory
DESCRIPTION:Please join us May 2nd for a one-hour talk from Paulo Ferreira\, International Iberian Nanotechnology Laboratory\, titled: \nSeeing Small: Revealing the Atomic Structure of Li-ion Battery LiMn2O4 Cathodes and 2D MoS2 Materials by Advanced Electron Microscopy \nAbstract – Aberration-Corrected TEM/STEM has emerged as powerful tool for the characterization of\nnanomaterials as it enables structural imaging at resolutions below 0.1 nanometers while performing\nchemical analysis at the atomic level. In this talk\, a brief overview of Aberration-Corrected\nTEM/STEM will be presented and related to the quest for investigating nanomaterials. Subsequently\,\ntwo examples that demonstrate the power of these techniques in providing scientific insight will be\ndiscussed. \nFirst\, the atomic structure of one of the cathode chemistries for Li-ion batteries – Li[Mn2]O4 – will be\npresented. This material is particularly appealing due to the moderate capacity and high rate\ncapabilities associated with its cubic spinel framework\, but it suffers from capacity loss\, attributed to\nthe dissolution of Mn to the electrolyte. In this work we use HAADF-STEM to show that a restructured\nsurface is formed in this material\, where a stable surface layer of Mn3O4\, followed by Li1+xMn2O4\nsubsurface with retention of bulk LiMn2O4 is formed. In addition\, by using differential phase contrast\n(DPC) STEM we were able to determine the Li\, Mn and O atomic positions\, thus providing a novel\ninsight into the migration of these species within the structure of LiMn2O4. \nIn the second part of the talk\, the atomic electrostatic configuration of the 2D material MoS2 and some\nof its point defects will be presented. The use of DPC-STEM allow us to observe not only the\nstructure of the materials at atomic level with greater sensitivity\, but also to obtain images\nproportional to the projected potential\, the projected electric field and the projected charge\ndistribution. In particular\, this talk will focus on the investigation of S mono- and divacancy defects in\nmonolayer MoS2\, the two most common point defects associated with the material. The results\nindicate a reduction of the experimental projected electric field at the single S vacancy and divacancy\nsites\, which have strong implications with respect to the properties of MoS2\, particularly in relation to\nthe forces experienced by adatoms on its surface. \nBio – Paulo Ferreira is currently a Full Professor in the Department of Mechanical Engineering at IST\,\nUniversity of Lisbon\, Portugal\, as well as the Head of the Advanced Electron Microscopy\, Imaging and\nSpectroscopy Center and the Leader of the Atomic Structure-Composition of Materials Group at the\nInternational Iberian Nanotechnology Laboratory (INL)\, Portugal.

SUMMARY:Converge to Transform: Interdisciplinary STEM Seminar Series- Teri W. Odom
DESCRIPTION:Join us May 3rd\, at 11am for the next speaker in our Converge to Transform: Interdisciplinary STEM Seminar Series as we hear from Dr. Odom in talk titled: \nShape Effects and Designer Nanoconstructs for Nanomedicine \nAbstract- Nanotechnology offers unique strategies for minimally invasive and localized approaches to diagnose and treat diseases. For example\, nanoparticles have been explored in a range of applications\, including as drug delivery vehicles\, imaging probes\, and therapeutic agents. Although increased therapeutic efficacy has been realized\, direct visualization of how engineered nanoparticles interact with specific organelles or cellular components has been limited. Such interactions will have implications for fundamentals in cancer biology as well as in the design of translational therapeutic agents. This talk will describe how drug-loaded gold nanostars can behave as optical probes to interrogate how therapeutic nanoconstructs interact with cells at the nanoscale. We will focus on model cancer cell systems that can be used to visualize how gold nanoconstructs target cells\, rotate\, and translate on the plasma membrane\, are endocytosed\, and are trafficked intracellularly. Critically\, differences in translational and rotational motion between spherical and star-shaped nanoconstructs indicate that the nanoparticle scaffold geometry affects how targeting ligands present and bind to cell-membrane receptors. That nanoparticle shape can preserve ligand activity of nanoconstructs in vitro will have important implications for engineering designer nanoconstructs for nanomedicine. \nBiography- Teri W. Odom is Joan Husting Madden and William H. Madden\, Jr. Professor of Chemistry and Chair of the Chemistry Department at Northwestern University. She is an expert in designing structured nanoscale materials that exhibit extraordinary size and shape-dependent optical and physical properties. Odom has pioneered a suite of multi-scale nanofabrication tools that have resulted in plasmon-based nanoscale lasers that exhibit tunable color\, flat optics that can manipulate light at the nanoscale\, and hierarchical substrates that show controlled wetting and super-hydrophobicity. She has also invented a class of biological nanoconstructs that are facilitating unique insight into nanoparticle-cell interactions and that show superior imaging and therapeutic properties because of their gold nanostar shape. \nOdom is a Member of the American Academy of Arts and Sciences (AAAS) and a Fellow of the Materials Research Society (MRS)\, the American Chemical Society (ACS)\, the Royal Society of Chemistry (RSC)\, the American Institute for Medical and Biological Engineering (AIBME)\, the American Physical Society (APS)\, and Optica [formerly the Optical Society of America (OSA)]. Select honors and awards include: the RSC Centenary Prize; the ACS National Award in Surface Science; a Research Corporation TREE Award; a U.S. Department of Defense Vannevar Bush Faculty Fellowship; a Radcliffe Institute for Advanced Study Fellowship at Harvard University; an NIH Director’s Pioneer Award; the MRS Outstanding Young Investigator Award; the National Fresenius Award from Phi Lambda Upsilon and the ACS; an Alfred P. Sloan Research Fellowship; and a David and Lucile Packard Fellowship in Science and Engineering. \nOdom was founding Chair of the Noble Metal Nanoparticles Gordon Research Conference (GRC) and founding Vice-Chair of the GRC on Lasers in Micro\, Nano\, Bio Systems. She was an inaugural Associate Editor for Chemical Science and founding Executive Editor of ACS Photonics. Currently\, Odom is Editor-in-Chief of Nano Letters. \n  \nThis one-hour seminar will take place in the ASRC auditorium\, and broadcast via Zoom. All registrants will receive instructions to obtain a Cleared4 Pass to enter the building.  \nTo register for this event>>> \nFor further questions about this hybrid event\, please contact: \nShelby Truitt \nstruitt@gc.cuny.edu

We aim to identify\, characterize and manipulate programs in and out of the neurons to achieve axon regrowth and behavioral recovery. Our latest work has revealed glial metabolism and neuronal mechanosensation as critical mediators of axon regeneration\, and potential therapeutic targets for treating neural injury. \nWei Min\, PhD\nProfessor of Chemistry\nDept of Chemistry & Dept of Biomedical Engineering\nKavli Institute for Brain Science\, Columbia University \nTowards Mapping Metabolic Tissue Atlas\nUnderstanding metabolism is of great significance to decipher various physiological and pathogenic processes. While great progress has been made to profile gene expression\, how to capture organ-\, tissue-\, and cell-type-specific metabolic profiles (i.e.\, metabolic tissue atlas) in mammalian systems is lagging behind. Here we will present a metabolic imaging technology by integrating advances in optical spectroscopy\, chemical biology and data science. This allows us to identify spatially-resolved metabolic signatures of brain and tumor\, tissue and cell-type specific metabolic profile in situ. Overall\, the integrated platform has great potential to map metabolic atlas ranging from cellular scale\, tissue-scale\, to organ-scale. \nFor info and questions\, please contact Dr. Ye He: yhe1@gc.cuny.edu
