Advanced 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

About One Class of Operators Inclusions
Моделирование и анализ информационных систем, 2012 The operator inclusion 0 ∈ A(x)+N(x) is studied. The main results refer to the case, when A – a bounded operator of monotone type from a reflexive space into conjugate to it, N – a conevalued operator. No solution criterion of the viewed inclusion is set

Fixed point results on nonlinear composition operators A ∘ B $A\circ B$ and applications
Journal of Inequalities and ApplicationsThis paper investigates a class of composition operators: the nonlinear operator T = A ∘ B $T=A\circ B$ and the sum-type operator T = A ∘ B + C $T=A\circ B+C$ , where A, B, and C are either single or bivariate operators. Here, “∘” denotes the composition

Solving Variational Inequalities with Monotone Operators on Domains Given by Linear Minimization Oracles [PDF]
, 2014 The standard algorithms for solving large-scale convex-concave saddle point problems, or, more generally, variational inequalities with monotone operators, are proximal type algorithms which at every iteration need to compute a prox-mapping, that is, to ...

Maximal monotonicity of dense type, local maximal monotonicity, and monotonicity of the conjugate are all the same for continuous linear operators [PDF]
Pacific Journal of Mathematics, 1999 Several stronger notions of monotonicity have been introduced during the last few decades as those of Gossez's maximal monotonicity, Fitzpatrick and Phelp's local maximal monotonicity, Simon's monotonicity. It is shown in this paper that for continuous linear monotone operators, these notions coincide and are equivalent to the monotonicity of the ...

3D‐Printed Sulfur‐Derived Polymers With Controlled Architectures for Lithium‐Sulfur Batteries
Advanced Functional Materials, EarlyView.Rheology‐guided formulation design for direct ink writing enables the fabrication of 3D sulfur copolymer cathodes with controlled architectures for lithium‐sulfur batteries. The printed electrodes exhibit multiscale porosity and high sulfur utilization, delivering enhanced electrochemical performance compared to conventional cast electrodes.

Ergodic theory for monotone Reich–Suzuki type nonexpansive operators
Journal of Fixed Point Theory and ApplicationsA recent study on nonexpansive monotone operators on partially ordered Banach spaces revealed that the sequence of Cesàro means converges to a fixed point, but also plays an instrumental role in the convergence analysis of the Picard successive ...

On the Property of Monotonic Convergence for Multivariate Bernstein-Type Operators
Journal of Approximation Theory, 1995 The authors mention first that many sequences \((L_ n)\) of one- dimensional linear positive operators satisfy the monotonicity property: \(L_ nf \geq L_{n + 1}f\), if \(f\) is a convex function. For example, in the case of Bernstein polynomials \(B_ nf\), by using expressions, in terms of second-order divided differences, for the remainder term and ...

Advanced Functional Materials, EarlyView.Multi‐metal Cu─Ce─Ag nanoparticles harness synergistic interactions to drive efficient electrochemical CO2 reduction reaction toward C2+ products at high current densities. Ag enhances CO production, Ce modulates Cu oxidation states, and together they boost *CO coverage and local pH to enhance C─C coupling, enabling record C2+ yields with suppressed ...

Matrix Hermite-Hadamard type inequalities [PDF]
, 2013 We present several matrix and operator inequalities of Hermite-Hadamard type. We first establish a majorization version for monotone convex functions on matrices. We then utilize the Mond-Pecaric method to get an operator version for convex functions. We
