Mg Substitution Improves the Surface Stability of High‐Voltage Spinel Cathodes under Accelerated Aging Conditions

open access: yesAdvanced Functional Materials, EarlyView.
LiNi0.5Mn1.5O4 lithium‐ion battery cathodes exhibit poor cycling stability due to surface reconstruction and electrolyte degradation at high voltage. This work demonstrates that partial Ni substitution with Mg prevents surface reconstruction and creates a corrosion‐resistant surface layer during the early stages of cycling, hence reducing electrolyte ...

Inverse Problem on the Steiner Wiener Index

open access: yesDiscussiones Mathematicae Graph Theory, 2018
The Wiener index W(G) of a connected graph G, introduced by Wiener in 1947, is defined as W(G) =∑u,v∈V (G)dG(u, v), where dG(u, v) is the distance (the length a shortest path) between the vertices u and v in G. For S ⊆ V (G), the Steiner distance d(S) of

On a nonlinear inverse problem in viscoelasticity

open access: yesVietnam Journal of Mechanics, 2009
We consider an inverse problem for determining an inhomogeneity in a viscoelastic body of the Zener type, using Cauchy boundary data, under cyclic loads at low frequency.

Nanodiamond‐Infused Microgels for pH‐Tunable Rheology, Lubrication, and UV Protection

open access: yesAdvanced Functional Materials, EarlyView.
Microgels consisting of swollen polyacrylic acid polymer networks, impregnated with nanodiamonds provide protection from ultraviolet (UV) radiation harmful to human health. Nanodiamonds enable UV blockage and control of the rheology (flow) and lubrication (skin‐feel) of these microgel‐skincare‐mimics.
