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 ...

It seems that significant nanoparticle risk studies are just like London buses, you wait ages for one to arrive and then two come along together.
Last month we had the Poland et al. study concerning the hazardous nature of MWCNT. This highly reported study was the first to explicitly test the hypothesis that long carbon nanotubes behave ...

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 ...

In the last week, Cosmetics Design Europe ran an article that caused quite a stir in the nano-world. The article, entitled ‘Professor compares nanomaterials to asbestos’ began with “Nanomaterials used in cosmetics have been compared to the invisible airborne killer, asbestos, by a high-profile chemistry professor at the BA Festival of Science in ...
