Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications
Advanced Functional Materials, EarlyView.Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

JSME international journal. Ser. 3, Vibration, control engineering, engineering for industry, 1989 This paper presents the results of an investigation into the effectiveness of a circular cutting tool with a slit tooth on aerodynamic noise reduction. The aerodynamic noise from a circular cutting tool is caused by vortices generated behind a tooth. It is possible to reduce the aerodynamic noise by controlling the vortices.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1989 The prediction of aerodynamic noise radiation from a circular cutting tool with a columnar tooth model is made. The noise level is calculated by a theoretical expression with the Karman Vortex model. Particularly, the change in the noise level with tooth length and tooth diameter is calculated.
