Research on graphene has made great strides in recent years. However, to fully harness its potential in applications such as desalination membranes, sensors, and energy storage and conversion, a d ... Graphene, a carbon layer just one atom thick, is considered a wonder material: extremely stable, highly conductive, and optically transparent. For a long time, it appeared just as transparent to water: measurements of the water contact angle — a meas... [3573 chars]
