Constitutive behavior and microstructural evolution in Ti–Al–Si ternary alloys processed by mechanical milling and spark plasma sintering

Journal of Materials Research and Technology, 2020
Severe plastic deformation is closely related to the microstructural behaviors of intermetallics or grain refinement by mechanical milling and subsequent rapid sintering process, i.e. high energy ball milling and spark plasma sintering.

Native Lignin Migration and Clustering in Wood: Superhydrophobic, Antimold, and Tribonegative Layers for Rain‐Driven Electrification

Advanced Functional Materials, EarlyView.
This study proposes a sustainable solution for rainwater‐driven energy harvesting by harnessing the intrinsic properties of lignin in wood. The first demonstration of an all‐wood tribonegative material for liquid–solid triboelectric nanogenerators is presented, eliminating the need for fluorine‐containing polymers and functional additives. Abstract The

Strain weakening and superplasticity in a Bi-Sn eutectic alloy processed by high-pressure torsion

, 2014
High-pressure torsion (HPT) was conducted on disks of a Bi-Sn eutectic alloy under a pressure of 6.0 GPa. The microstructural evolution was studied by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Measurements of Vickers

Comprehensive Si Anode Design for Sulfide‐Based all‐Solid‐State Batteries: Insights into Si‐Electrolyte Synergy for Mitigating Contact Loss

Advanced Functional Materials, EarlyView.
Silicon anodes in sulfide‐based all‐solid‐state batteries suffer from interfacial instability caused by volumetric fluctuations and contact degradation, restricting their practical implementation despite high capacity. This study presents design strategies that leverage controlled active material expansion and an elastic recoverable anolyte to form an ...
