Locally finite minimal non-FC-groups

open access: yes, 1989
We recall that a group G is an FC-group if for every x∈G the set of conjugates {xg|g∈G} is a finite set. Our interest here is with those groups G which are not FC groups while every proper subgroup of G is an FC-group: such groups are called minimal non ...

Additivity of the algebraic entropy for locally finite groups with permutable finite subgroups

open access: yes, 2020
Additivity with respect to exact sequences is, notoriously, a fundamental property of the algebraic entropy of group endomorphisms. It was proved for abelian groups by using the structure theorems for such groups in an essential way. On the other hand, a

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

open access: yesAdvanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Harnessing Phase Separation for the Development of High‐Performance Hydrogels

open access: yesAdvanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Modulating the Charge Transfer Channels via Constructing Charge‐Assisted Hydrogen‐Bonded Organic Frameworks for Enhanced Photosynthesis of Hydrogen Peroxide

open access: yesAdvanced Science, EarlyView.
This work reports a strategy of engineering charge‐assisted hydrogen bonds to tailor charge transfer channels in HOFs, significantly improving their performance in photocatalytic H2O2 production. ABSTRACT The production of H2O2 via artificial photosynthesis is often limited by inefficient charge‐carrier separation, causing significant charge ...

Spatially Selective Solvation Chemistry by Local Charge Enrichment for Stable Potassium‐Metal Anodes

open access: yesAdvanced Science, EarlyView.
A MoC/NC functional intermediate medium preferentially interacts with KFSI to reconstruct the interfacial solvation structure and form a KF‐rich inorganic SEI. The synergistic integration of the electronically insulating SEI and MoC/NC suppresses electron tunneling, enables fast and balanced K+/electron transport, and promotes uniform K deposition for ...

Groups with few non-((locally finite)-by-Baer) subgroups

open access: yes, 2011
In this note we study groups with few non-((locally finite)-by-Baer) subgroups and we prove that if G is a locally graded group satisfying the minimal condition on non- ((locally finite)-by-Baer) subgroups or having finitely many conjugacy classes of non-

Flexible Unusual Ternary‐Component Graded‐Modulus Dielectric Films with High‐Density Capacitive Energy Storage

open access: yesAdvanced Science, EarlyView.
Hierarchical PP–LSR107–BaTiO3 nanocomposite films are fabricated by one‐step extrusion and stretching for roll‐to‐roll manufacture, combining high energy storage and processing flexibility. LSR107 surrounds BaTiO3‐rich regions, locating amorphous PP, decreasing defects, and introducing deep traps that homogenize the electric field and suppress charge ...
