From 2020 Science:I’m
looking at an electron microscope image of a carbon nanotube - as I
cannot show it here, you’ll have to imagine it. It shows a long,
straight, multi-walled carbon nanotube, around 100 nanometers wide and
10 micrometers long. There is nothing particularly unusual about
this. What is unusual is that the ...

So you want to make or use carbon nanotubes, but you are worried about handling then safely. What do you do? The good news is that the UK Health and Safety Executive has just published an information sheet that addresses just this question. Risk management of carbon nanotubes is (according to the blurb) “specifically about the ...

From 2020Science.org:
Twelve months ago today I held a bag of multi-walled carbon nanotubes up
before a hearing of the U.S. House Science Committee. I wanted to
emphasize the discrepancy between the current state of the science on
carbon nanotubes, and a tendency to classify this substance as the
relatively benign material graphite from ...

Why nano? Why care? For non-nanotech initiates, an obsession with nanotechnology must sometimes seem a bizarre occupation of the sad and lonely. And even within the nanotechnology community, who hasn’t had occasional doubts over the legitimacy of singling out “nano” as something special? Yet occasionally a piece of work ...

Mix carbon nanotubes and asbestos together (metaphorically) and you get an explosive mix—at least if news coverage of the latest publication coming out of Professor Ken Donaldson’s team is anything to go by. The research—published on-line today in Nature Nanotechnology—is the first to explicitly test the hypothesis that long carbon nanotubes ...

On March 18th, the science fiction writer Arthur C. Clarke died in his home in Sri Lanka at the age of 90. A master developer and assembler of ideas, Clarke will be remembered fondly by many for igniting their enthusiasm for science, and how it might be used to better our lives. His passing leaves a hole in the ranks of science heroes ...

I have on my desk a plastic bag of carbon nanotubes—2 grams of dry, 60% purity single walled carbon nanotubes to be precise—bought from Cheap Tubes Inc. for the princely sum of $80. And I am wondering what to do with them. Despite the cosy assurances of the Manufacturers Safety Data Sheet that these are no more harmful than pencil ...
