Systematic Review on Additive Friction Stir Deposition: Materials, Processes, Monitoring and Modelling

Inventions
Emerging solid-state additive manufacturing (AM) technologies have recently garnered significant interest because they can prevent the defects that other metal AM processes may have due to sintering or melting.

Shaping Liquid Crystal Rubbers by Chemical Potential Gradient

Macromolecular Rapid Communications, EarlyView.
Depositing a low molecular weight liquid crystal drop onto a uniformly aligned LCE leads to non‐uniform swelling, enabling temporary shape changes and bending actuation. These deformations are quantitatively modeled for different alignment conditions, and methods to permanently lock desired shapes are explored.

Basalt Fiber Surface Modification for Improved Interaction With Polyamide‐6 for High‐Performance Automotive Applications

Polymer Composites, EarlyView.
Amino‐silane treatment improves the basalt fiber–PA6 interface, enhancing composite performance. ABSTRACT Basalt fiber‐reinforced polymer (BFRP) composites have emerged as sustainable alternatives to glass fiber (GF) composites, but their performance is often controlled by the quality of the fiber–matrix adhesion.

Reconciling Granular Hydrogel Microstructure and Mechanics via a Temporary Thermo‐Responsive and Cell‐Invadable Matrix

Small, EarlyView.
Thermo‐responsive granular hydrogels (TRGHs), composed of microparticles and an interstitial matrix, exhibit thermo‐responsive mechanical properties and allow cell infiltration. This system effectively addresses the conventional compromise between mechanical strength and porosity observed in granular hydrogels.
