Analytical Chemistry Seminar: Professor Jim Grinias

Analytical Seminars Greener and Faster Separations with Capillary Liquid Chromatography, Professor Jim Grinias - Chemistry, Rowan University The need for “greener” analytical techniques is becoming increasingly important in various industries based on a desire to work towards net-zero emissions. Although the contributions of measurement science may be small relative to other aspects of production in terms of energy consumption and waste generation, every aspect of a workflow must be investigated to minimize the total impact of a given process. In this presentation, we will discuss the impact of transitioning to capillary-scale separations on solvent consumption and waste generation relative to analytical-scale HPLC. Additionally, the use of a compact instrument platform with lower power consumption based on the use of reduced pumps and LED sources for absorbance detection will be described. For many applications in the pharmaceutical industry, results that are comparable to those obtained with larger instruments operated at… Event interval: Single day event.

Inorganic Chemistry Seminar: Professor Michael Neidig

Inorganic Seminars "Down the Rabbit Hole: Illuminating the Organoiron Species Central to Organic Synthesis" Professor Michael Neidig- Chemistry, University of Oxford Host: Julie Kovacs Despite the success of iron-based catalysts for transformations in organic chemistry, including cross-coupling and C-H fucntionalization reactions, a detailed molecular level understanding of these systems has remained elusive. This limitation is in stark contrast to palladium chemistry, where detailed studies of active catalyst structure and mechanism have provided the foundation for the continued design and development of catalysts with novel and/or improved catalytic performance. The use of an experimental approach combining advanced inorganic spectroscopies (Mössbauer, magnetic circular dichroism, electron paramagnetic resonance), density functional theory studies, synthesis and kinetic analyses enables the direct evaluation of the active iron species in iron catalyzed transformations in organic chemistry, providing a critical mechanistic… Event interval: Single day event.

Organic Chemistry Seminar: Assistant Professor Erin Stache

Organic Seminars "Light-to-Heat (Photothermal) Conversion Promotes High Activation Barrier Reactions " Assistant Professor Erin Stache - Chemistry, Princeton University Host: Alshakim Nelson Photon-driven processes have become a powerful tool for achieving challenging bond cleavages and formations. Photocatalysis offers temporal and spatial control with low-energy light, which has been widely advantageous for efficiently building molecular complexity from simple starting materials. The judicious choice of photocatalysts enables the precision of reactivity that is rarely achieved with other forms of catalysis and heating. An underused area of photocatalysis is light-to-heat (photothermal) conversion. Irradiation of specific nanoparticles or dyes with visible light creates intense thermal gradients in a photothermal conversion process. In contrast to bulk heating, where the temperature remains uniform across a reaction medium, substrates would only experience thermal energy within a few nanometers of excitation under temporal… Event interval: Single day event.

Analytical Chemistry Seminar: Assistant Professor Gabe Nagy

Analytical Seminars "Bioanalytical Applications and Fundamental Studies Enabled by High-Resolution Cyclic Ion Mobility Separations Coupled to Mass Spectrometry" Assistant Professor Gabe Nagy - Chemistry, University of Utah Host: Matt Bush Ion mobility spectrometry-mass spectrometry has emerged as an orthogonal and complementary analytical technique to liquid chromatography-tandem mass spectrometry in omics-based analyses. Carbohydrate-containing molecules, such as human milk oligosaccharides and glycolipids, are notoriously difficult to characterize, largely owing to their high degrees of isomeric heterogeneity. Thus, new analytical methodologies are required to improve the confidence of their characterization. In the first portion of this seminar, the use of cyclic ion mobility spectrometry-mass spectrometry (cIMS-MS) in conjunction with multiple tandem mass spectrometry-based strategies is presented as a new method toward the de novo sequencing of carbohydrate-based molecules. Recently, new insights from high-resolution ion… Event interval: Single day event. Campus location: Bagley Hall (BAG). Campus room: BAG 154. Accessibility Contact: chem59x@uw.edu.

Physical Chemistry Seminar: Professor Ki Tae Nam

Physical Seminars "Peptide Encoded Chiral Inorganic Nanomaterials" Professor Ki Tae Nam - Materials Science and Engineering, Seoul National University Host: David Masiello From small molecules to entire organisms, evolution has refined biological structures at the nanoscale, microscale and macroscale to be chiral—that is, mirror dissymmetric. Chiral nanoscale materials can be designed that mimic, refine and advance biological chiral geometries, to engineer optical, physical and chemical properties for applications in photonics, sensing, catalysis and biomedicine. The idea that inorganic materials can be chiral seems to be counterintuitive. In this talk, I will discuss about a new mechanism that can generate chiral nanomaterials based on the interaction between chiral peptides and high index plane of metal surface. The enantioselective interaction of chiral molecules and high-Miller-index facets can break the mirror symmetry of the metal nanocrystals. I will also discuss about interesting optical properties of these chiral… Event interval: Single day event. Accessibility Contact: chem59x@uw.edu. Event Types: Lectures/Seminars.

Organic Chemistry Seminar: Assistant Professor Laura Dassama

Organic Seminars "Exploiting metabolic vulnerabilities in pathogenic bacteria" Assistant Professor Laura Dassama - Chemistry, Stanford University Host: Lauren Rajakovich Increased human exposure to pathogens couples with rising antibiotic resistance and slow antibiotic development to pose a nearly insurmountable human health challenge. My work aims to discover proteins critical for pathogen survival, to reveal important insights into their mechanisms of action, and to develop chemical tools that precisely modulate their functions. By focusing on pathogens with limited or unique metabolic capabilities, we aim to discover novel biomarkers and antibiotic targets that are less likely to evade inhibitors. This talk will describe our use of informatics and other “omics” methods along with protein biochemistry and biophysics to accelerate the proteome-wide discovery of critical metabolite handling proteins in human pathogens.

Inorganic Chemistry Seminar: Assistant Professor Carl Brozek

Inorganic Seminars "Size-Dependent Behavior of Porous Nanocrystals" Assistant Professor Carl Brozek - Chemistry, University of Oregon Host: Douglas Reed and Daniel Gamelin Synthesizing metal-organic frameworks (MOFs) as nanoparticles is critical for their large-scale processability in real-world technologies and is poised to alter wide-ranging MOF behaviors, especially those related to transport phenomena. Little is known about controlled synthetic techniques, however, and studies into the impact of nanosizing physical properties have only just begun. Here, we present synthetic methods and mechanistic models that enable the precise preparation of MOF particles with conductive, magnetic, optical, and dynamic-bonding behavior distinct from their bulk counterparts.  These results include the first analysis of MOFs by solution-state spectroscopy and electrochemistry, revealing size-dependent phenomena and interfacial chemistry impossible to observe with conventional framework materials. Taken together these results offer tools… Event interval: Single day event. Campus location: Bagley Hall (BAG). Campus room: BAG 260. Accessibility Contact: chem95x@uw.edu.

Analytical Chemistry Seminar: Professor Ji Xin Cheng

Analytical Seminars "Seeing the Unseen Using Molecular Fingerprints" Professor Ji-Xin Cheng - Engineering, Boston University Host: Daniel Fu Spectrochemical imaging, using intrinsic fingerprint spectroscopic signals from molecules as a contrast mechanism, opens a new window for understanding life at the molecular level and also enables molecule-based precision diagnosis of diseases. Yet, the intrinsic spectroscopic signal, especially the vibrational signals from chemical bonds, is weaker than the fluorescence signal from a dye by many orders of magnitude. Detecting such weak signal from a tight focus (i.e. a small volume of ~1 femtoliter) under a microscope is extremely challenging and was considered nearly impossible. Ji-Xin Cheng devoted his career to overcoming such daunting barrier through developing advanced chemical microscopes over the past 25 years. In this lecture, Cheng will tell his journey of serendipity-driven innovation, scientific discovery, clinical translation, and entrepreneurship in the growing field of… Event interval: Single day event.

Physical Chemistry Seminar: Associate Professor Loren Kaake

Physical Seminars "A Polymer Thermodynamics Approach to Organic Mixed Conductors" Associate Professor Loren Kaake - Chemistry, Simor Fraser University Host: David Ginger Organic mixed conductors can transport both ions and electronic charge carriers. Many devices which leverage this property have been developed, including biosensors, energy storage materials, light emitting electrochemical cells, organic electrochemical transistors, and neuromorphic computing elements, to name a few. The problem is fundamental to this class of materials and their electrochemical properties. More broadly, the problem of mixed conduction sits at the crossroads of polymer physics and activity-based approaches to electrochemical equilibria.   Our group works with in-operando spectroscopy and electrochemical methods to develop the basic science describing the kinetics of ion transport in organic mixed conductors. By varying the position of the contact (top versus bottom) we show that ion transport is not affected by electric fields perpendicular… Event interval: Single day event.
