About the seminar: The design of paramagnetic coordination complexes with temperature-dependent chemical shifts is a major goal in biomedicine as it would allow temperature to be measured in vivo by MRI. While such behavior is well-established in lanthanide complexes on account of their magnetic anisotropy, transition metal thermometry is still in its nascent stages. Our laboratory reports two Fe(II) […]

Abstract: Despite many excellent medical achievements in the field of cancer therapies, resistance to chemotherapy as well as disease relapses remain a huge clinical challenge. One of the strategies in designing new anticancer therapeutics is the use of compounds based on metal ions surrounded by selected ligands (metal drugs). Different metal centers may exhibit different […]

Abstract: Vanadium remains one of the most adaptable yet underappreciated elements in inorganic chemistry, capable of shifting oxidation states, geometries, and reactivities in ways few metals can match. This seminar explores how deliberately designed scorpionate and pseudo-scorpionate ligand frameworks enable precise control over vanadium coordination environments, unlocking new structure–function relationships across materials and molecular systems. […]

Abstract: Glycans regulate many biological processes, but weak and transient carbohydrate-protein interactions are difficult to detect in native settings, and disease-associated glycosylation changes are often hard to exploit. In this seminar, I will present two complementary chemical strategies that convert glycan recognition into actionable readouts for discovery and targeting. First, I will introduce carbohydrate-directed labeling […]

Abstract: Vanadium coordination chemistry is a vast field with many niches. Although not that prevalent on earth, vanadium has found many uses. This seminar will share the results of two distinct avenues of inquiry involving similar vanadium-containing starting materials and the branching in studies performed and potential applications. At the heart of it all is […]

Dr. Jackie Chaparro will describe a large-scale effort to profile the metal concentrations in 500 foods using ICP-MS, a collaborative effort with the Periodic Table of Foods Initiative.

Abstract: Single-stranded nucleic acid aptamers, also known as synthetic antibodies, are widely used in sensing owing to their high selectivity and the range of detectable target analytes. A major challenge, however, is the fabrication of aptamer-based sensors with sufficiently small dimensions to enable localized, spatially resolved measurements in complex biological environments. In this talk, our […]

Abstract: Mastery over solid-state ion transport is paramount for broad diversity of applications and technologies, including batteries, fuel cells, neuromorphic computing, and beyond. Both static and dynamic disorder play a crucial role in dictating ion diffusion processes in the solid state. Our work seeks to understand and harness disorder across time and length scales to […]

About the seminar: Two-dimensional (2D) transition metal dichalcogenides (TMDCs) such as monolayer MoS2 exhibit strong excitonic effects and tunable electronic states that make them promising materials for photoelectrochemical energy conversion. In these atomically thin systems, the bandgap is not fixed but undergoes bandgap renormalization (BGR), shifting the conduction (ECB) and valence (EVB) band edge positions, in […]
