Development of Sensing Systems for Real-Time, Water Quality Measurements
Abstract: As the world strives for sustainable and healthier living, advances in technology are paving the way for a future when monitoring to ensure safe drinking water is widely available and affordable to everyone. Brewer Science is developing next-generation water quality sensing systems that enable real-time water monitoring. Our sensors can measure pH, temperature, and conductivity as well as trace levels of analytes such as lead and nitrate. The theory and capabilities of our sensor technology will be presented in this seminar.

Conformer-specific Desorption in Interstellar Ices Probed by Chirped-pulse mm-Wave Rotational Spectroscopy
Abstract: A new technique developed by our group for the detection of molecules desorbed from an ice surface using broad-band rotational spectroscopy will be presented. The approach permits interrogation of molecules that have undergone the slow warmup process of temperature-programmed desorption (TPD), analogous to the warmup phase of icy grains in the interstellar medium as they approach the central protostar. The detection is conformer- and isomer-specific and quantitative, as afforded by chirped-pulse rotational spectroscopy. To achieve this, we combine ice TPD with buffer gas cooling, followed by detection in the millimeter-wave regime. In this presentation, the sublimation of n- and ipropanol, the former of which may be in five different conformational isomeric forms, and which display distinct desorption profiles, will be described. The limited conformational isomerization and temperature-dependent relative yields of n-propanol conformers observed show that the desorption is highly conformer-specific. In addition to propanol, the sublimation of propyl cyanide will also be presented, where the relative abundances of the anti and gauche conformers following room-temperature gas-phase injection into a 25 K buffer gas cell are compared to that which is observed following TPD from an ice surface. The conformer distributions observed in the gas phase from room-temperature injection are then used to determine their relative energies, an important parameter needed to interpret the isomer and conformer abundances derived from astronomical observations. We find the gauche conformer to be the most stable species by ~97±21 cm-1. We further examine the relative conformer abundances following ice desorption, which are distinct from those following the gas-phase introduction. The ratios measured off the ice correspond to a conformer temperature of ~56 K, which is much lower than their sublimation temperature of 170 K.

Van der Waals Topological Magnets and Superconductors

Zoom seminar ID: 915 2072 1543

Abstract: The breaking of time-reversal symmetry in topological insulators leads to novel quantum states of matter. One prominent example at the two-dimensional limit is the Chern insulator, which hosts dissipationless chiral edge states at sample boundaries. These chiral edge modes are perfect one-dimensional conductors whose chirality is defined by the material magnetization and in which backscattering is topologically forbidden. Recently, van der Waals topological magnet MnBi2Te4 emerged as a new solid-state platform for studies of the interplay between magnetism and topology. I will present an overview of our progress toward controlling topological phase transitions and chiral edge modes in MnBi2Te4. First, I will establish how topological properties are intimately intertwined with magnetic states. I will then demonstrate electrical control of the number of chiral edge states and the discovery of chiral edge modes along crystalline steps between regions of different thicknesses and how these modes can be harnessed for the engineering of simple topological circuits. Finally, I will discuss the engineering of the superconducting state in topological insulators and demonstrate Pauli paramagnetic limit violation in atomically thin flakes of a topological superconductor candidate.

Novel Physical Phenomena in Nano-arrays and Nanostructures
Abstract: Nanostructures and nano-arrays with spatial periods near optical wavelengths offer a platform to control light-matter interactions, that can lead to novel phenomena in nanoplasmonics, nanophotonics, and quantum information science. We describe gold-coated nanoarrays, that show unusual extraordinary optical transmission phenomena. Quantum dots embedded within the nanocup arrays show a radiative decay rate that is enhanced by as much as a factor of 20, from the interaction of the strong optical field of the nano-array with the luminescent quantum dot. We describe how nano-arrays can enhance the light-outcoupling from organic light-emitting diodes, through diffractive effects. We describe insulating nano-arrays formed by replica-molding on elastomeric substrates that exhibit unusual surface electric potential distributions, that are formed by intricate nanoscale patterns of surface tribocharge. Experimental work combined with computational simulations in these applications will be discussed.

DiffDockDiffusion Steps, Twists, and Turns for Molecular Docking

Zoom seminar ID: 915 2072 1543

Abstract: Molecular docking, the process of predicting how small molecule ligands bind to proteins, is pivotal in drug design. Our work introduces a novel perspective by conceptualizing molecular docking as a generative modeling challenge. We present DiffDock, a diffusion generative model that operates on the complex, non-Euclidean manifold of ligand poses, efficiently navigating through the translational, rotational, and torsional degrees of freedom essential for accurate docking. Our empirical results showcase DiffDock's superiority, achieving a 38% top-1 success rate (RMSD<2Å) on the PDBBind dataset, markedly surpassing both traditional (23%) and other deep learning methodologies (20%). Notably, DiffDock demonstrates remarkable performance on computationally folded structures, achieving more than double the accuracy of existing methods. This talk will delve into the intuition and methodology behind DiffDock, and its strengths and limitations.
