Two‐Step Thermal Upcycling of Flexible Printed Circuit Board Waste Into Metallic Copper Nanoparticles: Synthesis and Characterization

Advanced Materials Technologies, EarlyView.
A two‐step thermal upcycling process converts flexible printed circuit board waste into high‐purity copper nanoparticles using polymer degradation and arc discharge. The synthesized nanoparticles exhibit controlled morphology and high metal purity.

Linking Polyelectrolyte Modification and Enzyme‐Catalyzed Phenolic Acid Functionalization of Cellulose Fiber for Functional Foams

Advanced Materials Technologies, EarlyView.
Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing

Chitin‐Chitosan Cryogels for the Reversible Sequestration and Recovery of Heavy Metals From Wastewater

Advanced Materials Technologies, EarlyView.
Chitin‐chitosan cryogels with degrees of N‐acetylation from 12.2% to 71.4% are fabricated by dissolution, coagulation and lyophilization for the sequestration of heavy metals from water. Colorimetry and differential pulse voltammetry showed controlled adsorption and desorption capacities for As5+, Co2+ and Cu2+, making this material attractive for ...

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface

Advanced Materials Technologies, EarlyView.
Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

Autonomous Reconfigurable Modular Conductive Hydrogels for Adaptive and Degradable Bioelectronic Interfaces

Advanced Materials Technologies, EarlyView.
Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.

Twisting Lamellae Triggering Circular Polarized Luminescence of Chromophoric Moieties in Banded Spherulites With Evolution of Homochirality

Advanced Optical Materials, EarlyView.
Crystallization‐mediated hierarchical chirality is shown to transform molecular stereochemistry into macroscopic circularly polarized luminescence. Twisted PLA crystalline lamellae generate asymmetric surface stress and chiral steric environments that direct achiral chromophore organization, producing opposite CPL responses in PLLA and PDLA matrices ...
