“Trees go high-tech: process turns cellulose into energy storage devices “

[below in Finnish, shortly]

This is exciting – through some process it is possible to make cheap superconductors out of cellulose:

OSU chemists have found that cellulose – the most abundant organic polymer on Earth and a key component of trees – can be heated in a furnace in the presence of ammonia, and turned into the building blocks for supercapacitors.

These supercapacitors are extraordinary, high-power energy devices with a wide range of industrial applications, in everything from electronics to automobiles and aviation. But widespread use of them has been held back primarily by cost and the difficulty of producing high-quality carbon electrodes.

The new approach just discovered at Oregon State can produce nitrogen-doped, nanoporous carbon membranes – the electrodes of a supercapacitor – at low cost, quickly, in an environmentally benign process. The only byproduct is methane, which could be used immediately as a fuel or for other purposes.

Once more it goes to show that industries and research related to the paper and pulp industry can foster important innovations, and with environmentally sound results even.
