Using high-energy electron beam as the energy source and taking advantages of high kinetic energy and low reflection characteristics of e-beam, the researchers directly induced polyimide precursor into a 3D porous graphene crystal film.
To create the new fracture electrostimulation device, researchers started with a triboelectric nanogenerator, a thin-film device with microstructured surfaces that converts mechanical energy produced by tiny movements into electric power.
Nanomaterials found in consumer and health-care products can pass from the bloodstream to the brain side of a blood-brain barrier model with varying ease depending on their shape - creating potential neurological impacts that could be both positive and negative.
