Efficient and mechanically robust stretchable organic light-emitting devices by a laser-programmable buckling process

Nature Communications, 2016
Highly stretchable organic light-emitting diodes tend to suffer from a lack of mechanical robustness. Here, Yin et al. fabricate ordered buckled films by laying flexible light-emitting diodes on laser-ablated, prestretched substrates. The devices exhibit

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.
