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 ...

Atomic Precision CoCu Heterodimers with Pseudo-D_3h Symmetry Enable Tandem Nitrate Reduction. [PDF]

Adv Sci (Weinh)
The Co─Cu heterodimer anchored on nitrogen‐doped graphene oxide substrate facilitates electrochemical nitrate reduction in alkaline medium. Co site promotes water dissociation to supply a proton, while Cu sites enhance nitrate adsorption and activation.

Pyrolysis-Free Formed Cooperative Coupling Pt-Co Dual-Functional Sites for Saline Electrolysis with High Adaptability. [PDF]

Adv Sci (Weinh)
Through a mild pyrolysis‐free route, cooperative coupling of single cobalt atoms (CoSA) and fully exposed platinum nanoclusters (PtNC) is assembled. As expected, the as‐prepared catalysts PtNC/CPF‐Co exhibit dual‐functional performance and high adaptability, demonstrating low overpotentials of 44 mV for HER and 340 mV for OER at 10 mA cm−2 in saline ...

Verification of the linear matching method for limit and shakedown analysis by comparison with experiments [PDF]

, 2013
The Linear Matching Method (LMM), a direct numerical method for determining shakedown and ratchet limits of components, has seen significant development in recent years. Previous verifications of these developments against cyclic nonlinear finite element

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 of asphalt pavements considering temperature effect [PDF]

, 2022
Shakedown limit has been perceived as a useful guidance in pavement structure design against rutting. However, temperature, as one key factor influencing the shakedown limit of asphalt pavements, has barely been considered.

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 ...

Structural shakedown: a new methodology for estimating the residual displacements

Journal of Civil Engineering and Management, 2016
A vector of residual forces of the ideally elastic-plastic structure at shakedown is obtained by solving the static analysis problem. A unique distribution of the residual forces is determined if the analysis is based on the minimum complementary ...

Effect of surface compressive residual stress introduced by surface treatment on fatigue properties of metallic material

MATEC Web of Conferences, 2018
This study considers shakedown in evaluating the fatigue limit of metals with compressive residual stress at the surface. We begin by applying tension-compression fatigue tests to ASTM CA6NM under conditions of controlled load and displacement to obtain ...

Shakedown loading optimization under constrained residual displacements—formulation and solution for circular plates

Journal of Civil Engineering and Management, 2002
The adapted plate load optimization problem is formulated applying the non-linear mathematical programming methods. The load variation bounds satisfying the optimality criterion in concert with the strength and stiffness requirements are to be identified.
