High quality graphene wafers fabricated using beetle tech

High quality graphene wafers fabricated using beetle tech

Many beetles, like ladybugs, have the ability to stick to things as they walk underwater. They can do this by trapping tiny bubbles within hair-like structures on their feet. Researchers at the National University of Singapore have used a similar bubble trick to develop a way to make high quality graphene films. Their new technique is the first which can ...

Bill Gates funds creation of thin, light, impenetrable graphene condoms

Bill Gates funds creation of thin, light, impenetrable graphene condoms

Graphene is incredibly thin and light, and prevents all but the smallest molecules from passing through it (it’s an excellent water filter, for example). Condoms, though an excellent barrier against unwanted contaminants, are neither thin nor light — which is why they reduce sensation, and why some people really don’t like wearing them. The Bill and Melinda Gates Foundation, realizing ...

The world’s most smallest FM radio transmitter – made from graphene

The heart of every radio transmitter is a reliable oscillator. Creating small, and tunable, oscillators that can maintain a precise frequency when conditions like temperature, pressure or humidity change, can be challenging. Engineers from Columbia University have just revealed to us the world’s smallest FM transmitter, which they managed to build around a nanoscale graphene oscillator. Details of their device ...
