Transporting Spin: A Graphene And Boron Nitride Heterostructure Creates Spin Signals Large Enough To Be Used In Real Life Applications

Graphene Flagship scientists based at the University of Groningen, The Netherlands, have created a device based on a bilayer of graphene and boron nitride which shows unprecedented spin transport efficiency at room temperature. Highlighting the potential of creating devices containing graphene and related materials, the spin signal measured here is so large that it can […]

Understanding Graphene Batteries

This Graphene Battery User’s Guide, which has been created for both scientists and non-scientists, explains the working principle of graphene batteries, their benefits, and details immediate, actionable steps that can be taken to begin developing a graphene battery.

Graphene-Based Nanotube Biosensor Could Detect Single Biomolecules Efficiently

Biosensors are devices that can detect biological molecules (“analytes”) in blood, air or water. They are increasingly being used in the fields of biological research, medical diagnostics, drug development and even security. In spite of ongoing advancements, there is still a demand for enhanced portable bio sensing devices that are convenient to use for Doctors […]

Using Graphene Based Solar Cells for Solar Applications

The dependence upon renewable energy is becoming more obvious, the need for efficient solar cells is becoming vital, particularly when they are one of the cheapest and easiest ways to generate clean energy. In general, solar cells are not that efficient. However, latest advances in graphene-based solar cells have witnessed the reflectance of solar rays […]
