    Dr. Irshad Kammakakam (Nazarbayev University) will present an organic division seminar next Friday, May 22 in CHEM 2104 at 11:30 AM titled "Bridging Microporous Architectures and Imidazolium-Mediated Functionality for Environmental Technologies" Join us!
    abstract text: Prof. Kammakakam’s group focuses on the design and synthesis of imidazolium-mediated functional polymers for high-impact environmental and energy applications, including gas separation, sensing, ion separation, and water purification. His group has developed advanced Ionic-PIMs (Polymers of Intrinsic Microporosity) membranes with enhanced CO2 affinity, high permeability, and strong thermal stability through the incorporation of ionic liquid functionalities into rigid polymer backbones. Using innovative synthetic strategies and molecular dynamics simulations, the group demonstrated exceptional gas separation performance and resistance to free volume collapse. More recently, the lab has expanded this platform to imidazolium-based hydrogels with enhanced ionic conductivity and mechanical robustness for applications such as mercury separation and advanced environmental remediation.

    Dr Gabbai is hosting Dr. Alexandra Velian from the University of Washington, to present her seminar “Molecular Catalysts Go Nano: Installing Active Sites on Clusters and Nanosheets” on Wednesday, April 29 in CHEM 2104 at 11:30 AM.
    Seminar flyer with ATM logo and headshot of Dr. Velian.
Abstract text: A central research goal in the Velian group is to create next-generation single-atom catalysts that harness cooperativity between the active site and chemically non-innocent supports. To emulate defect sites in inorganic heterogeneous catalysts in a controlled fashion, we embed well-defined active sites on clusters and two-dimensional nanosheets.
The first part of this seminar will introduce a class of atomically precise nanoclusters featuring discrete active sites that dynamically engage with the metal chalcogenide support and with substrates.
The second part will present an orthogonal approach to catalyst design, where principles of organometallic phosphine chemistry are used to anchor single-site active centers on two-dimensional black phosphorus nanosheets. Molecular synthetic and characterization strategies are used to probe bonding and functionality.

    Dr. Marc Greenberg from Johns Hopkins University will be presenting a seminar on “Chemical Tools for DNA-Protein Cross-Link Formation and Study” on Monday, April 27th at 11:30 AM in CHEM 2104. Join us!
    Seminar flyer with abstract text: DNA-protein cross-links (DPCs) are highly toxic lesions formed via a variety of chemical pathways and as intermediates in enzyme transformations. DPCs are potent blocks of helicases, as well as DNA and RNA polymerases. DPCs are associated with aging and diseases such as cancer. Recently, DPCs were also shown to result in chronic inflammation. Despite their importance, our understanding of DPCs has lagged that of other forms of DNA damage. For instance, the first protease identified to repair DPCs in human cells (SPRTN) was only identified in the past decade. Our group is developing chemical tools for producing DPCs. These tools are useful for studying DPCs extra- and intracellularly, and are potentially useful pharmacologically. Recent published and unpublished investigations will be presented.
