Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

I/Q Demodulator Based Optical Camera Communications

IEEE Photonics Journal, 2022
Visible light communications achieve wireless communications using light sources such as lighting fixtures and electric signboards. The light sources need to blink at high speed to avoid flickering. However, the blinking frequency is much higher than the frame rate of the general-purpose cameras that are integrated into consumer devices such as ...
