What can you make with graphene?

The potential of graphene is limited only by our imagination.

• Biomedical. Graphene’s unique properties allow for ground-breaking biomedical applications: targeted drug delivery; improved brain penetration; DIY health-testing kits and ‘smart’ implants.
• Composites and coatings.
• Electronics.
• Energy.
• Membranes.
• Sensors.

Can you make things out of graphene?

For all its high-tech capacities, graphene is surprisingly easy to make at home—in very small quantities. The only raw materials needed are graphite (for instance, the broken-off point of a standard Number 2 pencil) and some fairly robust adhesive tape.

What is graphene * 1 point?

Graphene is the name for a single layer (monolayer) sheet of carbon atoms that are bonded together in a repeating pattern of hexagons. Since a typical carbon atom has a diameter of about 0.33 nanometers, there are about 3 million layers of graphene in a 1 mm thick sheet of graphite.

What can graphene oxide be used for?

Graphene oxide (GO), an oxidized derivative of graphene, is currently used in biotechnology and medicine for cancer treatment, drug delivery, and cellular imaging. Also, GO is characterized by various physicochemical properties, including nanoscale size, high surface area, and electrical charge.

What is graphene used for GCSE?

Like graphite, graphene conducts electricity well because it has delocalised electrons that are free to move across its surface. These properties make graphene useful in electronics and for making composites .

Can you turn coal into graphene?

Ohio University researcher, Dr. Gerrardine Botte, has developed a simple method of producing graphene from inexpensive and widely available coal. The process begins by subjecting ground coal to electrolysis. The resulting coal char is used as a carbon source for graphene growth via chemical vapor deposition (CVD).

What is graphene used for medicine?

Graphene is important to improve applications in medicine: cancer therapies, disease diagnostic tools, tissue engineering, implants, DNA sequencing, biomarker, transfer of genetic material, as well as in the combined field of biomedical imaging and neuroscience.

Can graphene be cut?

Yes, you can cut graphene. Graphene is just the monolayer form of graphite, a ubiquitous industrial material which can certainly be cut into smaller pieces. If you can cut graphite, then you can certainly cut graphene.

What is fullerenes GCSE?

Fullerenes are molecules of carbon atoms with hollow shapes. Their structures are based on hexagonal rings of carbon atoms joined by covalent bonds. Two examples of fullerenes are buckminsterfullerene and nanotubes .
