Thermal Equilibria of Optically Thin, Magnetically Supported, Two-Temperature, Black Hole Accretion Disks

, 2010
We obtained thermal equilibrium solutions for optically thin, two-temperature black hole accretion disks incorporating magnetic fields. The main objective of this study is to explain the bright/hard state observed during the bright/slow transition of ...

Synergistic Spin‐Polarization and Single‐Atom Engineering in Magnetic Heterojunctions for Efficient Solar Water Splitting

Advanced Science, EarlyView.
High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

基于库仑应力改变和地震活动性研究巴颜喀拉块体周缘强震序列的触发关系及其构造意义

Dizhen xuebao, 2018
自本世纪以来，青藏高原巴颜喀拉块体周缘密集地发生了7次MW≥6.5强震事件，包括伤亡惨重的2008年汶川MW7.9地震和2017年九寨沟MW6.5地震。本文根据这7次强震事件中先前地震对后续地震的库仑应力改变（dCFS）的计算结果，结合基于ETAS模型得到的背景地震活动性的变化结果，研究了强震间的触发关系，以试图解释发生在环巴颜喀拉块体的几次强震的发震机理并探讨其构造意义。结果表明，各个强震的库仑应力变化与其造成的背景地震活动性变化呈正相关，并且在这7次强震中，汶川地震对芦山地震有显著的触发作用 ...

On slip pulses at a sheared frictional viscoelastic/ non deformable interface

, 2000
We study the possibility for a semi-infinite block of linear viscoelastic material, in homogeneous frictional contact with a non-deformable one, to slide under shear via a periodic set of ``self-healing pulses'', i.e.

Integrating Machine Learning With Constant‐Potential Simulation to Unravel Charge‐Transfer Mechanisms in Electrochemical Nitrogen Fixation

Advanced Science, EarlyView.
Integrating interpretable machine learning with the fixed‐potential method reveals a novel mechanism: the catalytic activity of the electrochemical nitrogen reduction reaction is governed by partial charge transfer, induced by variations in the intermediate potential of zero charge under constant potential.

Modelling wave-induced sea ice breakup in the marginal ice zone

, 2017
A model of ice floe breakup under ocean wave forcing in the marginal ice zone (MIZ) is proposed to investigate how floe size distribution (FSD) evolves under repeated wave breakup events.

Symmetry‐Driven Unconventional Magnetoelectric Coupling in Perovskite Altermagnets: From Bulk to the Two‐Dimensional Limit

Advanced Science, EarlyView.
The symmetry‐driven coexistence of altermagnetism and (anti)ferroelectricity in perovskites shows a strong dimensional dependence. Upon reducing the system from bulk to the two‐dimensional limit, only C‐type antiferromagnetic order retains ferroelectrically switchable altermagnetism, whereas A‐ and G‐type orders become conventional antiferromagnets ...
