Effective control over the crystalline contact plane and microstructure of a naphthalenediimide‐bithiazole copolymer enables high‐performance n‐type thermoelectrics. While rubbing alignment induces a detrimental edge‐on orientation, subsequent solvent vapor‐induced re‐orientation facilitates a favorable mixed face‐on/edge‐on morphology.

Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures
Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.

Tailored Diketopyrrolopyrrole Derivatives for Efficient Deep‐Red Organic Lasers
Tailored diketopyrrolopyrrole derivatives exhibit high stable amplified spontaneous emission with single or dual bands. Incorporated into distributed‐feedback lasers based on one‐ and two‐dimensional dichromated‐gelatin diffractive gratings, these materials provide a robust, flexible platform for integrated organic deep‐red light sources. ABSTRACT Deep‐

3D Hydrodynamic Flow Lithography
ABSTRACT Continuous‐ and stop‐flow lithography are widely used to fabricate multi‐dimensional microstructures whose cross‐sectional morphology is dictated by the flow profile of multiple co‐flowing streams. Here, we introduce three‐dimensional hydrodynamic flow lithography (3D HFL), a platform for programmable generation of multi‐layered flow profiles ...

A multicomponent supramolecular hydrogel integrating cell‐adhesive and antibacterial peptides within an alginate‐cellulose nanofibril matrix is developed. Peptide co‐assembly simultaneously strengthens the hydrogel network, improves extrusion printability, and imparts cell‐adhesive and antibacterial functions, offering a versatile platform for ...
