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)

Major changes are happening in the world of 3D printing and additive manufacturing materials, machines, and software. If the industry -- and the design engineers and OEMs it serves -- are to grow, all three areas must become much more tightly integrated.
The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
Coatings and sealants are getting more versatile to deal with miniaturization and multiple materials, and tougher to meet requirements for higher reliability.
Improved simulation and analysis tools are helping to develop more and better once-exotic alloys, plus good old aluminum, for lighter aerospace designs with less waste.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
