Fixed point theorems on certain class of contractive mappings [PDF]
, 1988 The objective of this paper is to introduce the concepts of a H-contractive mapping and a π -ultimately contractive mapping on cartesian product of two metric spaces, and to show that, under certain restrictions, such mappings have a fixed ...

Advanced Functional Materials, EarlyView.A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Two Coexisting Pathways to Volatility in Valence‐Change Memory Devices
Advanced Functional Materials, EarlyView.Volatile VCM‐type memristive devices exhibit current relaxation after resistive switching, but their microscopic origin remains debated. Using pulsed measurements and a new Tunnel‐DLTS approach on Pt/SrTiO3/Nb:SrTiO3 devices, we show that post‐SET volatility is predominantly ionic, while electronic contributions—arising from quasi‐Fermi‐level ...

Sequences of mappings converging to a contraction mapping
, 2015 We consider sequences of mappings \(\{T_{\alpha}\}\) from a metric space X into itself, which converge to a contraction mapping T. We define \(T^{n+1}=T_{n+1}T^ n\), \(T^ 1=T_ 1\) and we investigate the convergence of the sequence \(\{T^ nx\}\) for any point x in X.

Advanced Functional Materials, EarlyView.A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).

Electrostatic Superlattices Beyond 1:1 Stoichiometry
Advanced Functional Materials, EarlyView.Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl
