A light twisting material created from nano semiconductors may become an optical game changer.
Chiral assembly from Achiral nanoclusters. The magical size nano -cluster science can form a noise assembly through the Menniscas guided sedimentation. The degenerated excitation state is divided into a non -degreasing state when coupling is generated, and an excitation child couplet is generated in the CD spectrum. When the evaporated geometry is controlled, the Takada real film with the dominant…

The material acts as a biomimetic of teak wood and creates an environmental barrier coating.
The multiscale layered structure of teak wood provides excellent mechanical properties and environmental stability, which has inspired the biomimetic design of environmental barrier coatings. In this study, a multiscale nano Yb2Si2O7-Yb2SiO5 composite EBC with a layered structure similar to teak wood was realized by a new vapor/liquid phase alternating deposition method in plasma spray-physical vapor deposition (PS-PVD). In this process,…
