We present a dedicated end-station for solution phase high repetition rate (MHz) picosecond hard x-ray spectroscopy at beamline 15-2 of the Stanford Synchrotron Radiation Lightsource. A high-power ultrafast ytterbium-doped fiber laser is used to photoexcite samples 640 kHz, while data acquisition operates 1.28 MHz storage ring recording in an alternating on-off mode. The time-resolved measurements are enabled via gating detectors with 20 mA/70 ps camshaft bunch SPEAR3, mode available during...
The adsorption sensitivity of perfect, vacancy-defected and transition-metal (TM) doped Hf2CO2 towards H2S molecule was investigated using density functional theory (DFT). weakly adsorbed on the perfect substrate, appearance O-vacancy improved activity Hf2CO2. introducing TM-dopant (Ti, Cr Ni) enhanced stability molecule, which also enriched magnetic properties In addition, states diagrams indicated that improvement attributed to hybridisation between TM-d orbital molecule. findings can...
The ternary chalcogenide MnPSe3 monolayer recently gets a lot of attention because its two nonequivalent energy valleys. existence spin–orbit coupling (SOC) effect can cause the valley splitting around 24 meV. However, spin degeneracy is still kept in owing to antiferromagnetic between Mn2+ ions. interlayer van der Waals (vdW) heterostructures break symmetry and induce splitting. Here, we simulate MnPSe3/GeC vdW heterostructure investigate effects stacking on both excitation mode excitons...
The VORPAL finite-difference time-domain particle-in-cell simulation tool has traditionally been used for accelerator, electromagnetic, and plasma simulations. Approximately two years ago, a generalized PDE (partial differential equation) capability was added to the software, we are now developing this provide multi-physics simulations capability. Our project focus is on integrated thermal & electromagnetic superconducting RF accelerators. But interested in broadening scope of applications...
