"Fluorescent probes for monitoring metallo-beta-lactamase antibiotic resistance enzymes"
Abstract: Metallo-β-lactamases (MBLs) grant resistance to a broad spectrum of β-lactam antibiotics including last-resort carbapenems and is emerging as a global antibiotic resistance threat. Limited zinc availability adversely impacts the ability of MBLs to provide resistance, but many clinical variants have emerged that are more resistant to zinc scarcity. To provide novel tools to study metal ion sequestration in host-pathogen interactions and the dynamic metalation state of MBLs in these contexts, we are developing fluorescent probes that bind to the dizinc of active site. The development of reversible turn-on fluorescent probes for MBLs provides a means to monitor the impact of metal ion sequestration by host defense mechanisms and to detect inhibitor target engagement during the development of therapeutics to counter this resistance determinant. Recent developments in our lab along this research theme will be discussed.

"Si-Ge Nanowire Heterostructures and Devices"
Abstract: The combination of vapor-liquid-solid growth mechanism with
epitaxial this film growth allows the realization of band-engineered core-shell nanowire heterostructures, where the shell content and thickness can be accurately controlled. Understanding the electronic and structural properties of such heterostructures is not only of fundamental importance, but can have direct implications for aggressively scaled, non-planar complementary metal-oxide-semiconductor device. In this presentation we will discuss the growth and structural characterization of a set of silicon and germanium-based core-shell nanowires, the characterization of in strain such heterostructures which stems from the lattice mismatch between the different materials, as well as the realization of high performance field-effect transistors.

"Electrochemistry at material interfaces: from energy storage to synthetic muscle"
Abstract: Through the synthesis of new material interfaces, the Aubrey group seeks to understand and design materials that move and shape their environments, displaying unusual electronic phenomena with potential applications in energy storage, soft robotics, and microelectronics. The drive toward ever smaller electronic devices and the advent of 2D materials like graphene have motivated the search for other ångström-scale 2D and 1D materials with a greater diversity of electronic, magnetic, and surface structures. The Aubrey group has recently developed a new material interface between redox-active 2D materials and metallic surfaces, featuring a diversity of surface chemistries and intermolecular forces at the interface. Through these interfacial interactions between materials, we seek to control the coupling of chemical potential in one material to an induced mechanical strain in another. Systems like these provide a straightforward means of applying large changes in mechanical pressure to a material under ambient conditions and a possible method for fabricating non-biological muscular systems at the absolute smallest of length scales.
At solid-electrolyte interfaces, the complex coordination chemistry of multivalent ions like Mg2+ and Al3+ in solution has slowed the development of their electrochemistry outside of high-temperature molten salt reactors operating at 800-1000 ºC. Nonetheless, the reversible deposition of these metals from solutions near room temperatures could potentially enable exceptionally low-cost electrochemical energy storage solutions, 10 times less expensive than conventional lithium-ion batteries. To this end, the Aubrey group has recently developed a new class of aluminum electrolytes using organic pseudo-halides. Our current progress toward the realization of a room-temperature Al battery and outstanding challenges stemming from the fundamental coordination chemistry and electrochemistry of Al3+ in solution will be discussed.
