Advanced Healthcare Materials, EarlyView.ABSTRACT Sutures are crucial for tissue approximation and wound healing. Besides their strength limits requirement, they often fail to effectively address complications like infection and pain. Inspired by natural silk's “core‐sheath” structure, our suture features a wet‐spun core of n zinc‐fortified silk fibroin fibers (RSF‐Zn2+) after drawing with ...

Resolving the Structural Duality of Graphene Grain Boundaries
Advanced Materials, EarlyView.Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Structural Design and Performance Analysis of Novel Torsional Impact Tool
Shiyou jixie, 2017 The existing impact and rotary-impact rock breaking technology mostly use the axial impact and the shear action of the PDC bit to achieve high-efficiency rock breaking, but excessive axial force will cause the failure of PDC bit shear force, resulting in

A sequence environment modulates the impact of methylation on the torsional rigidity of DNA
Chemical Communications, 2018 We explain, with atomic-level detail, how DNA methylation may contribute to the regulation of biological processes. We show that DNA sequence environment modulates the impact of methylation on the physical properties of the double helix.

Advanced Materials, EarlyView.Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.
