DOI: 10.1002/adfm.202519080

Abstract: Anisotropic 2D materials such as black phosphorus (BP), GeS or CrSBr, exhibit direction‐dependent optical and electronic properties that are highly desirable for polarization‐sensitive detection, waveguiding, and directionally tuned transport. However, scalable fabrication of large‐area films… read more here.

DOI: 10.1002/adma.202507289

Abstract: Aerogels have been considered as super thermal insulators. However, they often exhibit less satisfactory mechanical properties for textile application due to their fragility and poor processability. These problems are overcome through a twisting‐induced fibrillation method,… read more here.
