New method to fabricate graphene sheet fabricated from camphor
Down To Earth ^ | August 19, 2019 | Susheela Srinivas

Graphene, a recently discovered wonder material, is increasingly sought after for its superior electrical, thermal, optical and mechanical properties. It is used in the manufacture of optoelectronic devices such as detectors, sensors and solar cells.

It is made up of one-atom-thick, honeycomb-like structure of carbon atoms. A significant challenge faced by scientists is the fabrication of large-area graphene sheets for devices. Finding a ‘green’ source for the carbon atoms is another hurdle.

Indian researchers have now developed a new method to fabricate graphene sheets from camphor — a readily available ingredient often used in religious rituals.

“Camphor is a plant product with abundant carbon elements required to derive graphene. All it needs is restructuring — breaking and making of chemical bonds — of the carbon atoms. So we explored the possibility and achieved this rearranging of elements of camphor to get graphene mono-layers,” said Indrajit Mukhopadhyay, lead researcher at the Pandit Deendayal Petroleum University, while speaking to India Science Wire.

The study results have been published in journal ACS Omega.

Indrajit Mukhopadhyay. Roll-calls in the military and schools must take an hour!

But... carbon is bad, right?

I would like to be on the graphene ping list if I am not.

Thank you.

Camphor gas is used in chemical chambers for training for of M3’s and M2 masks, the latest from the M17A1, in the military. It is toxic and can do a variety of damage. It is sometimes a replacement for tear gas.

In solid form an ingestion of 4 grams is lethal within 90 minutes. Not stuff to play with. If you want to use it, even the dosages sold be stores, study the MSDS to protect yourself.

You’re on the list. In post #6, see your name between ckilmer and EEGator?

I did, but wondered if you added it manually for this thread. Okay,.. lame.

Anyway, thanks. Didn’t remember signing up for this one. It may be low volume.

It does interest me.
