Optical Manipulation of Multiferroic Phases in BiFeO3 Thin Films

Advanced Materials Interfaces, EarlyView.
At the strain‐driven morphotropic phase boundary, optical control over the multiferroic rhombohedral and tetragonal phase mixture is demonstrated using above‐bandgap light illumination. The photoinduced charge carriers modify the electrostatic environment and induce the conversion into a single tetragonal phase.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Roll‐to‐Roll Manufacturing of Flexible Thermoelectric Semiconductors Using Low‐Level Direct‐Current Sputtering

Advanced Materials Technologies, EarlyView.
Roll‐to‐roll direct‐current sputtering enables room‐temperature manufacture of flexible bismuth telluride thermoelectric films. By identifying a low‐power deposition window that suppresses charge‐induced arcing, this work links sputtering conditions to film structure, charge transport, and thermoelectric performance, achieving a room‐temperature figure
