Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

Autocontinuity and convergence theorems for the Choquet integral [PDF]

open access: yes
Our aim is to provide some convergence theorems for the Choquet integral with respect to various notions of convergence. For instance, the dominated convergence theorem for almost uniform convergence is related to autocontinuous set functions ...

Tracking the Dynamic and Interactive Metal Oxidation Changes in CoFe, CoNi, and NiFe Bimetallic Hydroxides for Electrocatalytic Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Operando hard X‐ray absorption spectroscopy is applied to track the dynamic and interactive metal oxidation changes in iron group bimetallic hydroxides under different chemical and electrochemical conditions. It shows that Co and Fe oxidation are relatively equal and synchronized in CoFeOxHy.

Measures on monotone properties of graphs

open access: yesDiscrete Applied Mathematics, 2002
A monotone property \({\mathcal P}\) is one that is closed under isomorphism and under taking subgraphs. The graphs of \({\mathcal P}\) with vertex set \([n]\) will be denoted by \({\mathcal P}_n\). Various enumeration measures of monotone properties are investigated. In particular, results on the speed of \({\mathcal P}\), which is \(|{\mathcal P}_n|\)

Multi‐Ion Doping Controlled CEI Formation in Structurally‐Stable High‐Energy Monoclinic‐Phase NASICON Cathodes for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The graphical abstract illustrates the synthesis pathway, morphological feature, and thermodynamic feasibility of entropy‐engineered NASICON cathodes for sodium‐ion batteries. Abstract Overcoming the energy density limitations of sodium‐ion batteries (NIBs) requires innovative strategies to optimize cathode materials.

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

open access: yesAdvanced Functional Materials, EarlyView.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

The Polar Cone of the set of monotone maps

open access: yes, 2013
We prove that every element of the polar cone to the closed convex cone of monotone transport maps can be represented as the divergence of a measure field taking values in the positive definite matrices.Comment: to appear on Proc ...

Tuning the Electronic Structure and Spin State of Fe─N─C Catalysts Using an Axial Oxygen Ligand and Fe Clusters for High‐Efficiency Rechargeable Zinc–Air Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Monotone Measures Defined by Pan-Integral

open access: yesAdvances in Pure Mathematics, 2018
Given a pan-space  and a nonnegative measurable function f on measurable space (X, A), the pan-integral of f with respect to monotone measure μ and pan-operation  determines a new monotone measure  on (X, A). Such the new monotone measure  is absolutely continuous with respect to the monotone measure μ.
