Producing Ultrastiff Graphene with Direct Laser Writing
Graphene has exceptionally high in-plane strength but exceptionally low out-of-plane stiffness, making it flimsy and hard to handle. Here, researchers show that using a laser writing technique called optical forging increases graphene bending stiffness up to five orders of magnitude, opening venues for a plethora of new applications, such as GHz resonators and 3D scaffolds. Direct laser writing … Continue reading
