Just How Toxic Are Carbon Nanotubes?
11/29/2012

Researchers at Texas Tech University have come up with a new method for detecting CNTs in soils, which will help determine their toxicity. CNTs are so small that mean outer diameters of 13nm to 16nm are common in multi-walled tubes, shown here as grains partially smeared on paper (scale in centimeters).

Ironhorse,

Great parallel.  Burning "stuff" is a quick solution used too many places in the world.  When the fire is out, the stuff is gone and out of mind.  But what is out of mind oftimes becomes the stuff in the lungs, the bloodstream, the organs and cells.

As for the scented candles, hopefully the proliferation of LED "fake" candles on the store shelves this year lead to fewer scented candles that must be endured.  A Christmas wish for 2013 and beyond?

My point is 3 fold:

"Burning stuff" is how nature does it.  [I've been presented lake sediment data showing prehistoric fire events were quite periodic (every 25-27 years)]

It doesn't go away.

We evolved eating and breathing it.  (we didn't evolve eating grains)

Here are new recycled materials, new recycling machines, and other news about recycling 3D printed materials we've put together in one place.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Hospital-acquired infections and more home use of medical devices are shaking up device design, bringing more plastics into increasingly complex designs.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
