A Thermoreversible Gelation Pathway to Plant Cuticle‐Inspired Biopolymer Aerogel Monoliths Based on Network‐Spherulitic Crystal Assemblies

Advanced Materials, EarlyView.
To address functionality limitations in plant‐based and industrially compostable polymer aerogels, this work introduces bio‐inspired aerogels with broadened functionality. Inspired by functional plant tissues, lightweight biopolymer aerogels based on exclusively stereocomplex crystals are fabricated, featuring hierarchically macro‐/meso‐porous ...

Reactivity‐Guided Janus Graphene With Asymmetric Interfacial Electrostatics for Tunable Charge Transport

Advanced Materials, EarlyView.
Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.

A Superstrong and Ultratough Stretchable Electronic Conductor With Ultradurable Strain-Insensitive Electromechanical Performance. [PDF]

Adv Sci (Weinh)
We report a superstrong, ultratough, and fatigue‐resistant stretchable electronic conductor (SEC) integrating a viscoplastic quasi‐solid LM‐Ag alloy with a supramolecular elastomer. Unlike conventional LM, the alloy exhibits thixotropic flow, reduced surface tension, and enhanced interfacial interactions with the elastomer.

Ionic Liquid (IL) Compatibilization of Macropore‐Infused Nanocomposite Emulsion Thermosets (MINETs) for Structural Ion Transport

Advanced Materials Interfaces, EarlyView.
Macropore‐infused nanocomposite emulsion thermosets (MINETs) offer tunable multifunctionality due to their incorporation of structural resin, functional nanoparticles, and working fluid stabilized by surfactant. Here we show that if ionic liquid working fluids are introduced, structural capacitive (conductive particles) or separator (insulating ...

Effect of impeller tip clearance on cavitation in an axial-flow pump

Engineering Science and Technology, an International Journal
Cavitation in axial-flow pumps reduces efficiency, induces noise and vibration, and causes wear on metallic components. The existence of a tip clearance, coupled with the high rotational speed of the impeller, creates a favorable condition for cavitation
