Experimental study on water transfer of soil-rock mixtures under freezing action

Yantu gongcheng xuebao
The frost-heaving failure of earth-rock dam slopes is mainly caused by the combined action of sand and gravel cushion, frost heaving of dam fills and water migration.

Effects of heaving and pitching motions on underside aerodynamics of a sedan vehicle

Journal of Fluid Science and Technology, 2019
Unsteady pressure distributions around a simplified sedan automobile model were investigated by conducting dynamic wind-tunnel testing using the newly developed forced oscillating apparatus, HEXA-X3, which can produce 6-degrees-of-freedom motion.

Cooperative Goniopolar and Anomalous Nernst Transverse Thermoelectricity in Kagome Magnets

Advanced Materials, EarlyView.
A cooperative transverse thermoelectric mechanism is realized in kagome magnets, where axis‐dependent goniopolar effects and Berry curvature‐driven anomalous Nernst coexist within the same energy window. In MgMn6Sn6, this intrinsic synergy yields a record room‐temperature transverse thermopower of 15.6 µV K−1, establishing a general strategy for high ...

Type‐II Dirac Fermions in Monolayer In2O: Interplay of Magnetotransport, Spin Hall Effect, and Superconductivity

Advanced Science, EarlyView.
First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...
