Using diffraction results from slab calculations, we achieve spatial resolution 1.0--1.3...
High-pressure low-permeability gas reservoirs have a complex gas–water distribution, lack of unified interface, and widespread water intrusion in localized high areas, which seriously constrain sweet spot prediction development deployment. In this study, the high-pressure, sandstone Huangliu Formation Yinggehai Basin is taken as object, micro distribution mechanism main controlling factors are revealed by combining core expulsion experiments COMSOL two-phase flow simulations. The results...
Abstract Thermal X-ray emission from rotation-powered millisecond pulsars, shaped by gravitational lensing and the beaming of surface radiation, provides critical insights into neutron star properties. This approach has been focus observations with Neutron Star Interior Composition Explorer (NICER) mission. Using a semianalytic model to calculate pulse profiles, we investigate effects adopting incorrect models on inferred compactness stars. We demonstrate that assuming more centrally peaked...
We present a dynamical theory based on the invariant-embedding R-matrix scheme for calculating reflection high-energy electron-diffraction rocking curves. The method is shown to be accurate and numerically stable. Using Ag(001) Pt(111) surfaces as examples, we demonstrate importance of reaching proper numerical convergence in rocking-curve calculations. effect different models imaginary potential curves presented.
We show how the intensity enhancement of angle-resolved x-ray photoelectrons along emitter-scatterer internuclear directions can be used to monitor layer-by-layer growth Co on Cu(111). Specifically, we technique distinguish between fcc or hcp and determine precisely thickness at which stacking switches hcp. also interference patterns around each forward-focusing direction produce real-space images nearest-neighbor atoms in atomic plane above emitting atom.
