Ultrahigh Electric Charge Density Harvested From Pre-Compressed Ferroelectric Ceramics, Sergey I. Shkuratov, Jason Baird, Alexander S. Shkuratov, Christopher S. Lynch Apr 2025

Ultrahigh Electric Charge Density Harvested From Pre-Compressed Ferroelectric Ceramics, Sergey I. Shkuratov, Jason Baird, Alexander S. Shkuratov, Christopher S. Lynch

Mining Engineering Faculty Research & Creative Works

Ferroelectric elements of high-power electrical generators, utilizing the ability of ferroelectric materials to produce electric charge under mechanical stress, are subjected to either high-pressure shock or moderate-pressure impact loading. The results are reported herein on experimental investigations of a different mode for the generation of a high electric charge density, one that utilizes pre-compressed ferroelectric ceramics. Hard PZT 52/48 (Navy Type I/PZT-4) ferroelectric ceramic specimens were subjected to static uniaxial compressive stress parallel to polarization. At the moment of operation, the output terminals of the specimens were connected to an external circuit, and the applied stress was quickly removed, resulting …


Systematic Characterization Of The Homogeneous And Heterogeneous Hydrogen Halide Dimers, Yuan Xue, Gregory S. Tschumper Apr 2025

Systematic Characterization Of The Homogeneous And Heterogeneous Hydrogen Halide Dimers, Yuan Xue, Gregory S. Tschumper

Chemistry Faculty Research & Creative Works

This study systematically characterizes the four homogeneous and six heterogeneous hydrogen-bonded dimers formed by hydrogen halide pairs (HX/HY where X, Y = F, Cl, Br, and I). The notation HX⋯HY indicates the direction of the hydrogen bond from the HY donor to the HX acceptor. All stationary points reported for these ten dimer systems are fully optimized utilizing the MP2 and CCSD(T) ab initio methods in conjunction with quadruple-ζ correlation-consistent basis sets augmented with diffuse functions, and their nature is verified by harmonic vibrational frequency computations. The electronic dissociation energies (De) for all ten global minima are evaluated near the …

Many technologies involve immobilizing catalysts such as enzymes on surfaces, and the catalytic activities or functional efficiencies of these surface-bound catalysts can vary depending on orientations, localized binding sites, active sites, and intrinsic molecular nature. Accurate and rapid quantification of reaction products from surface-immobilized catalysts is crucial for understanding the selectivity, mechanisms, and reaction dynamics of catalytic systems and for revealing heterogeneous catalytic activities and reaction sites for applications such as biosensors and energy conversion/generation systems. Here, we demonstrate the feasibility of localized enzymatic activity measurements using microscale carbon dioxide (CO2)-sensitive ion-selective electrode (ISE) pipettes (0.5-2.5 μm tip …
