Microstructure and texture evolution in a magnesium alloy during processing by high-pressure torsion

Materials Research, 2013
Magnesium alloys often exhibit cracking and segmentation after equal-channel angular pressing (ECAP) at room temperature. With torsion shear deformation and a hydrostatic stress, high-pressure torsion (HPT) has an advantage over ECAP in the processing of

Wood Cellulosic Membrane With Abundant Nanochannels for Stabilizing Aqueous Zn‐Ion Batteries

Advanced Functional Materials, EarlyView.
A wood‐derived cellulosic membrane separator is developed to suppress dendrite growth in aqueous zinc‐ion batteries. Its aligned nanochannels and hydroxyl‐rich surfaces enable uniform Zn2+ flux, water immobilization, and interfacial stabilization. Zn||Zn cells achieve 1920 h of cycling, Zn||Cu cells maintain 99.5% Coulombic efficiency over 1000 cycles,

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

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.
