Intermediate Filament Protein BFSP1 Maintains Oocyte Asymmetric Division by Modulating Spindle Length

open access: yesAdvanced Science, EarlyView.
Different from mitosis, the female meiosis undergoes asymmetric division that produces haploid oocytes and polar body, which is essential for retaining maternal components to support subsequent fertilization and embryo development. However, the underlying mechanisms are still largely unknown.

A pathway of signals regulating effector and initiator caspases in the developing Drosophila eye [PDF]

open access: yes, 2002
Regulated cell death and survival play important roles in neural development. Extracellular signals are presumed to regulate seven apparent caspases to determine the final structure of the nervous system.

Nanoreactor‐Driven Uniform Nano ZnS Deposition in Tunable Porous Carbon Spheres for High‐Performance Zn‐S Batteries

open access: yesAdvanced Science, EarlyView.
In this work, a series of porous carbon spheres with tunable pore size, particle size, and shell thickness are designed as nanoreactors for the S‐ZnS redox reactions in Zn‐S batteries. The presence of abundant defects and oxygen‐containing functional groups facilitates efficient ion/electron transport throughout the reaction process, significantly ...

Graphene/h‐BN/ReS2 Heterostructure Operating in Fowler−Nordheim Tunneling Regime for Polarization‐Sensitive Fast Photodetector

open access: yesAdvanced Electronic Materials, EarlyView.
The authors demonstrate a bias voltage‐dependent anisotropic tunneling behavior by designing a ReS2‐based heterojunction operating in the Fowler–Nordheim tunneling regime. The device exhibits a dichroic tunneling current that surpasses the intrinsic anisotropy of ReS2, offering a new strategy to amplify directional responses in 2D materials for ...

Breaking Barriers: Centimeter‐Sized Single Layer WSe2 by Gold‐Mediated Exfoliation for Ambipolar Field Effect Transistors at Ultra‐Low Voltages

open access: yesAdvanced Electronic Materials, EarlyView.
2D transition metal dichalcogenides (TMDCs) are promising for next‐gen electronics. In this work, centimetrer‐sized single‐layer WSe2 is achieved via thermally activated gold‐mediated exfoliation. When integrated into solid‐state electrolyte gating field‐effect transistors, the devices exhibit ambipolar behavior, steep subthreshold swings down to 30 mV
