A Bifunctional Fibrous Scaffold Implanted with Amorphous Co2P as both Cathodic and Anodic Stabilizer for High‐Performance Li─S Batteries

open access: yesAdvanced Science, EarlyView.
An amorphous Co2P‐embedded porous carbon nanofiber membrane (A─Co2P/PCNF) via electrospinning/in situ phosphorization is developed to serve as the dual‐electrode stabilizer for Li─S batteries. The amorphization strategy enables more exposed undercoordinated Co sites with optimized d‐band centers, enhanced LiPSs adsorption/catalysis, and lithiophilicity‐

Radical‐Polar Crossover Bicyclization Enables a Modular Synthesis of Saturated Bicyclic Amines

open access: yesAdvanced Science, EarlyView.
Herein, we report the successful realization of a radical‐polar crossover bicyclization reaction from easily available cyclopropylamines and substituted alkenes through photoredox catalysis. This approach introduces an innovative methodology for the de novo synthesis of a diverse collection of 4/5‐, 5/5‐, 6/5‐,7/5‐ and 5/6‐fused saturated bicyclic ...

A Nanostructured Ru‐Mn‐Nb Alloy with Oxygen‐Enriched Boundaries for Ampere‐Level Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
Ru62Mn12Nb21O5 medium‐entropy alloy with a crystal‐crystal dual‐phase structure is deposited on a carbon cloth substrate by the magnetron sputtering method. The oxygen‐rich interface induced by the rich Mn phase and the poor Mn phase optimized the electronic structure of the catalyst, adjusted the adsorption and desorption processes of intermediates ...

Targeted Intervention Strategies for Maternal–Offspring Transmission of Christensenellaceae in Pigs via a Deep Learning Model

open access: yesAdvanced Science, EarlyView.
This study deciphers maternal‐driven microbial transmission in pigs using a deep learning model (maternal–offspring microbial transmission model), identifying Christensenellaceae R‐7 group as a key transmitted taxon. Filtered galacto‐oligosaccharides‐targeted Christensenellaceae R‐7 group alters offspring microbial functions via maternal ...

The Migrant Mother’s Silence in Her Mother Tongue as a Mothering Strategy

open access: yesContemporary Women's Writing
Abstract Historically silenced, literary mothers’ voices are finally now being given their due, but it is noteworthy that migrant mothers’ literary voices are yet to be fully heard. This essay focuses on literary representations of migrant mothers who refuse to speak their own mother tongue to their children.
