Synergistic Ion Transport and Spatial Confinement in Sb‐Embedded Hollow Carbon Nanofibers for Stable Na Metal Anodes

open access: yesAdvanced Science, EarlyView.
This work presents a 3D Sb‐embedded hollow carbon nanofiber (Sb@HCF) host for ultra‐stable Na metal anodes. Experimental analyses and theoretical simulations clearly uncovers that in situ formed Na‐Sb alloy guides uniform Na deposition and serves as efficient ion transport highways. The Sb@HCF‐based cells achieve exceptional cycling stability in half‐,

El etnógrafo como contrabandista. Tráfico de imágenes, propagación de conceptos y usos de la cultura material en la obra de Alfred Métraux [PDF]

open access: yes, 2013
The present paper develops a few hypotheses regarding the traffic of material culture in Latin America and its impact, both in the field con anthropologic knowledge and in the artistic vanguards of the first half of the twentieth century. The circulation

Printable Conductive Hydrogels for Electrochemical Biosensing and Soft Bioelectronic Interfaces

open access: yesAdvanced Science, EarlyView.
Flexible, conductive hydrogels that integrate printability, mechanical tunability, biocompatibility, and electronic performance remain challenging to achieve. Here, we develop 3D‐printable poly(ethylene glycol)–poly(pyrrole)‐ hydrogels with tissue‐like mechanics, high cytocompatibility, and robust electrochemical function.

β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

open access: yesAdvanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

Descalça vai uma ninfa: a propósito de um vilancete de Camões

open access: yesConvergência Lusíada
Neste artigo, mobilizamos o conceito-imagem da Ninfa, postulado pelo historiador da arte alemão Aby Warburg, para pensar a performance da personagem feminina que aparece no poema “Descalça vai para a fonte”, de Luís de Camões. Leanor, a moça que caminha

Self‐Assisted Charge Storage‐Release Mechanism Enabling Flexible Design of Biomimetic Triboelectric Nanogenerators

open access: yesAdvanced Science, EarlyView.
Inspired by the mimosa, this study develops a flexible triboelectric nanogenerator with a novel microneedle array and battery‐mimetic architecture. The device introduces a spontaneous charge self‐regulation mechanism that confines the electric field below the air breakdown threshold, and achieves an outstanding charge density of 396.50 µC m−2 ...
