Development Of A Pavement Rutting Model Using Shakedown Theory
International Journal on Pavement Engineering & Asphalt Technology, 2015 Abstract The rutting of flexible pavements during their exploitation is considered to be one of the main problems in UK as well as worldwide. It is a serious mode of distress alongside fatigue in bituminous pavements that may lead to premature failure, as indicated by permanent deformation or rut depth along the wheel load path, and results in early ...

Application of shakedown theory in the structural design of bituminous pavements [PDF]
, 2016 Excessive rutting, one of the major distress modes of bituminous pavements, is mainly caused by the accumulation of load-induced permanent deformation. However, current pavement design approaches against the excessive rutting are mainly developed using the theory of elasticity. Recently, a new pavement design approach based on the shakedown concept has

Atomic Precision CoCu Heterodimers with Pseudo-D<sub>3h</sub> 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 ...

O<sub>2</sub>-Accessible Fe-N<sub>4</sub> Active Site Density Boosts Efficient Oxygen Reduction to Fuel-Cell Level. [PDF]
Adv MaterThis 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.

<sup>*</sup>OH Adsorption-Mediated Electrochemical Oxidation of 5-Hydroxymethylfurfural to Selective 2,5-Furandicarboxylic Acid at pH 12. [PDF]
Adv Sci (Weinh)Under the weakly alkaline condition, at pH 12, the *OH adsorption–mediated mechanism of direct aldehyde oxidation is demonstrated to complete HMF oxidation to FDCA, obtaining >95% selectivity and yield. In OH−‐deficient media, high FDCA selectivity is achieved on the CuO/NiOOH interface, a synergistic active site, where Cu enhances *OH utilization, and
