Atomic Level Fabrication of Oxychloride Interface for High-Rate and High-Voltage Lithium-Ion Batteries. [PDF]
Angew Chem Int Ed EnglSynthesis 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 ...

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.

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 ...

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.

Shakedown of bolts with a one-sided propagating crack
Journal of Civil Engineering and Management, 2002 Cyclic strains of joints may cause formation of a crack or cracks in a bolt thus changing its loading conditions. After crack appearance in a bolt it can be used if its length does not exceed a critical one.
