Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor
Advanced Functional Materials, EarlyView.Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Fluoride Ion Uptake by Synthetic Apatites
Adsorption Science & Technology, 2009 Fluoride uptake by synthetic apatites from aqueous solutions was studied as a function of fluoride ion concentration. The phosphate minerals synthesized and considered included different varieties of phosphate minerals of the apatite group such as ...

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Advanced Functional Materials, EarlyView.The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Strictly join irreducible elements in the lattice of varieties of BL-algebras [PDF]
, 2017 The logic BL and its corresponding semantics, BL-algebras, were introduced by Petr Hajek in 1998. From then, many scholars investigated the structure of the lattice of the subvarieties of BL.

Advanced Functional Materials, EarlyView.This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

On varieties of orgraphs [PDF]
, 2001 In this paper we investigate varieties of orgraphs (that is, oriented graphs) as classes of orgraphs closed under isomorphic images, suborgraph identifications and induced suborgraphs, and we study the lattice of varieties of tournament-free ...

Advanced Functional Materials, EarlyView.In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.

MULLITE AND ITS ISOMORPHIC SUBSTITUTION OVERVIEW
Конденсированные среды и межфазные границы, 2018 The phase diagram of SiO2-Al2O3 is considered. The paper presents an overview of the methods of synthesising mullite, including the calcining of natural aluminosilicates, the Czochralski process (synthesising mullite from melt), the Verneuil process ...
