Executive Committee Meeting

Zoom Meeting

Note: I request that all officers, chairs of standing committees (e.g., commmunications, awards), and chairs of topical groups provide updates in our January agenda, specifically on page 2 and onwards. Please feel free to include flyers, links, and any info about upcoming events as well as robust summaries of recent events and activities. If you need the Executive Board to vote on a motion, the information must be provided in advance through this agenda. Note #1: If you cannot edit the file, please send me your changes and I can make the updates on your behalf, Note #2: If you have no report to make, please include "No updates at this time" in your relevant section.  Please update the agenda by MONDAY 08JAN2024 at the latest.  My hope is this will improve the efficiency of our meetings and help disseminate information amongst NJACS leadership. Let me know if you have any questions, comments, or concerns, and I look forward to seeing you next week. If you did not receive a Zoom invite, then register below and you will receive an email with the Zoom connection. Best, Sandra

NMR Seminar with Rongfeng Zheng

MS Teams

Title: Chalcogenide-Stabilized Metal Nanoclusters: Synthesis, Characterizations, and Applications Abstract: This seminar focuses on the atomically precise gold NPs, or NCs. Au25(SR)18 was selected as a model NC to investigate their magnetic properties, with pentanethiol, hexanethiol and octanethiol used as bonding ligands. Both negatively charged and neutral NCs were synthesized, and 1H/13C NMR were used for detailed structural analysis, as well as surface bonding ligand environment analyses. The anion NC (diamagnetic) and neutral (paramagnetic) NCs are compared and by using the diamagnetic chemical shifts as references, paramagnetic Knight shifts can be calculated. These shifts measure the spin density along the carbon chain of the surface ligand. Temperature dependent NMR was used to study the spin density effect. Density functional theory calculations were used to predict the spin density on Au25(SC8H17)18 and compared with the Knight shifts observed from the experiments. New magnetic properties were observed from the Knight shifts plots. Chalcogenide stabilized NCs, such as with selenolates and tellurolates, have been less investigated, especially their exchange reactions with thiolate. The reaction mechanism, specifically the site preferences and how the mixed ligand layer is distributed on the NCs surface in the exchange reaction, is much less understood. PhSeH and (PhTe)2 were used

NJ Mass Spectrometry Discussion Group Virtual Meeting

Webex meeting

The NJ Mass Spectrometry Discussion Group is pleased to announce our February Monthly Meeting.       Speaker: Jane Gale, Ph.D., ASMS Archivist/Historian Title: Decade by Decade:  An Historical Review of Mass Spectrometry and ASMS in the Second Half of the 20th Century Abstract: Following fifteen years of meeting as part of the American Society for Testing and Materials (ASTM, now ASTM International) a small group of influential mass spectrometrists broke away from the umbrella group to found the American Society for Mass Spectrometry.  Whereas in the early days talks at annual get-togethers were dominated by topics related to the oil industry, the newly formed ASMS had a broader focus and included lively discussions of everything from mechanistic studies of molecules in the gas phase to surface science studies of materials important to the electronics industry.  The growing Society became the premier US venue in which to present both fundamental research on the technique and applied research into its use in ever-widening fields of study.  This talk will follow the Society’s growth and development over the last 70+ years, incorporating into that history the vast array of scientific developments that enabled new areas of application.

NMR Seminar: Structural Determination of Neurodegenerative Disease-Associated Proteins Inside Cells

MS Teams

 Abstract The misfolded proteins associated with neurodegenerative disease can adopt a variety of different conformations, some of which are toxic. Because these proteins have identical amino acid sequences, the cellular environment clearly influences the final state, yet most structural studies do not include the cellular context and, perhaps because we are not studying the correct conformation, not a single therapeutic strategy for these diseases addresses the underlying protein misfolding pathology. Using new sensitivity-enhancement technology for solid state NMR spectroscopy, Dynamic Nuclear Polarization, we study protein structure in native environments -inside living cells -to reveal how both healthy and disease-relevant cellular environments influence protein structure. Because NMR reports quantitatively, with atomic level precision, on all sampled conformation, it can not only report on structural polymorphs but also provide experimental restraints on regions of intrinsic disorder, complementing insights from cryo-electron microscopy and tomography.Using this approach, we recently demonstrated that an amyloid fibril with a solved cryo-EM structure was polymorphic and found that when those fibrils were used to seed amyloid propagation in mammalian cells, the minority polymorph in the purified setting became the majority polymorph inside cells. With this approach we can understand the mechanism of protein-based inheritance of amyloid aggregates and
