Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Existence results for nonlocal multivalued boundary-value problems

open access: yesElectronic Journal of Differential Equations, 2006
In this paper we establish some existence results for nonlocal multivalued boundary-value problems. Our approach is based on existence results for operator inclusions involving a suitable closed-valued multifunction; see [2,3].

About analysis of some localized boundary-domain integral equations for a variable-coefficient BVPs [PDF]

open access: yes, 2007
Some direct localized boundary-domain integral equations (LBDIEs) associated with the Dirichlet and Neumann boundary value problems for the "Laplace" linear differential equation with a variable coefficient are formulated.

Boundary Value Problems for q-Dierence Equations and Inclusions with Nonlocal and Integral Boundary Conditions

open access: yesMathematical Modelling and Analysis, 2014
In this paper, we study boundary value problems for q-difference equa- tions and inclusions with nonlocal and integral boundary conditions. Some new exis- tence and uniqueness results are obtained by using a variety of xed point theorems.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
