The Nanotech BC Blog: Beetles, Wood and Nanotech

Speaking of using nanotech to benefit the environment, Nanowerk has a very good summary of some of the many ways that nanotechnology looks to be able to reduce greenhouse gases.

Global Warming is something we've been hearing about for a long time. It's only been comparatively recently that visible, serious consequences are starting to hit home. One of the least discussed but most serious consequences of a warming climate is the expansion of pests into new territories.

In BC that means the Mountain Pine Beetle. Thanks to a series of warm winters that caused the population of the Pine Beetle to explode, vast stretches of forests in British Columbia have turned rust red and died.

Unfortunately nanotechnology doesn't offer any easy solutions to the Pine Beetle problem. Pine Beetle damaged wood can be sold, but at reduced prices and this is hitting the forest industry hard. Nanotechnology cant protect the trees themselves, but it might be able to protect the economies that rely on forestry by enabling the creation of new high value products from damaged timber.

Nanocrystalline Cellulose is a product of plants derived through nanotechnology. As is so often the case when dealing with nanotech, nanocrystalline cellulose has properties that are quite different from its macro-scale counterpart, including "extraordinary catalytic, electrical and optical properties."

Nanocrystalline Cellulose is an example of how nanotechnology is allowing us to look at the resources we depend on and see them in a new way. By examining materials at the nano-scale we sometimes find uses and capabilities that nobody dreamed were there.
