Shakedown modeling of unsaturated expansive soils subjected to wetting and drying cycles [PDF]

E3S Web of Conferences, 2016
It is important to model the behavior of unsaturated expansive soils subjected to wetting and drying cycles because they alter significantly their hydro-mechanical behavior and therefore cause a huge differential settlement on shallow foundations of the ...

Atomic Level Fabrication of Oxychloride Interface for High-Rate and High-Voltage Lithium-Ion Batteries. [PDF]

Angew Chem Int Ed Engl
Synthesis of a lithium‐ion conductive aluminum‐based oxychloride (LAOC) thin film is realized by a facile atomic‐level chemical fabrication method. LAOC coating enables lithium cobalt oxide (LCO) cathode superior cycling performance at high rates and elevated voltages, owing to the fast interfacial ionic transport and excellent interfacial stability ...

O₂-Accessible Fe-N₄ Active Site Density Boosts Efficient Oxygen Reduction to Fuel-Cell Level. [PDF]

Adv Mater
This study investigates the role of hierarchical nanostructure design in optimizing oxygen mass transport for the oxygen reduction. Using atomically dispersed Fe–N–C catalysts with solid, yolk‐shell, and hollow structures, it demonstrates that the yolk‐shell architecture provides superior O2 accessibility to active Fe–N4 sites.

Shakedown Analysis of Layered Continuum [PDF]

, 2012
Failure of structures associated with repeated moving surface loads are typically caused by gradual deterioration rather than sudden collapse. This type of failure behavior is mostly due to the accumulation of plastic strains under repeated loadings ...
