Formation of Intermetallic Sludge Phases in AlMgSi Alloys with High Concentrations of Alloying Elements: A Drawback for Increasing Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Sludge phases with brittle fracture behavior form in AlMgSi alloys with high concentrations of alloying elements and negatively influence their ductility. The phase type mainly depends on the Si content and the concentration of minor alloying elements like Fe, Mn, Cr, and Mo strongly influences the number of sludge particles. The need for sustainable

High‐Concentration Mesogen‐Assisted Exfoliation of Low‐Dimensional Nanomaterials for Achieving Ultralow‐Temperature Actuations of Liquid Crystal Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

Molecularly Tailored Elastomeric Block‐Copolymers for Intrinsically Stretchable Organic Field‐Effect Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Molecular‐level engineering of SEBS elastomers is introduced for skin‐inspired electronics. By systematically modulating the S/EB molar ratio in SEBS, precise control is achieved over nanoscale morphology, mechanical properties, metal‐elastomer adhesion, and dielectric performance.
