Canada’s National Institute of Nanotechnology and cellphone breathalyzers

First a soap opera, of sorts and then the science.

Canada’s ‘morphing’ National Institute of Nanotechnology

It seems we in Canada no longer have a National Institute of Nanotechnology (NINT) as such. (sigh) The NINT been downsized and rebranded. Always part of Canada’s National Research Council (NRC), the NINT has been languishing for a number of years. The downsizing/rebranding has resulted in two new ‘entities’: the NRC Nanotechnology Research Centre and the NRC-UAlberta [University of Alberta] Nanotechnology Initiative. The original NINT was a joint venture between the Canadian federal government’s NRC and the province of Alberta, which was a co-funder with the institute (now initiative/research centre) itself being located at the University of Alberta. You can see the latest description of these agencies on this NRC Nanotechnology webpage.

For scandal mongers, the date the NRC Nanotechnology webpage was last updated is an interesting one:  March 14, 2018. My first posting about the ‘Montemagno affair’ was on March 5, 2018. Briefly, Carlo Montemagno was a US ressearcher and academic who was enticed to work at the University of Alberta with $100M of federal and provincial funding to be paid out over a 10-year period. His salary when he left about 1/2 way through his term was approximately $500,00 CAD per year. Departing in July/August 2017, Dr. Montemagno who headed up the “ingenuity Lab,” a kind of nanotechnology research and incubator project, moved to the Southern Illinois University (SIU) where he ran into some problems some of which seemed to stretch backwards to his time in Alberta. I did a followup two-part posting (April 26, 201 8 (part 1) after a student reporter from SIU dug up more material. This downsizing/rebranding seems to have been quite the cleanup job. By the way, Canada’s NanoPortal (mentioned in the March 5, 2018 posting) has currently ‘disappeared’.

Finally, the science

There is finally (it has been years) some sort of nanotechnology research from Alberta and the ‘initiative’. From a June 15, 2018 article by Jamie Sarkonak for the Edmonton Herald (in Alberta),

Cellphone breathalyzers may be on the horizon with the breakthrough by an Edmonton-based nanotechnology team.

The special sensors, called nano-optomechanical systems, are normally studied in airtight conditions. But the research of nanotechnologist Wayne Hiebert, published in the journal Science on Friday [June 15, 2018], has found the sensors work better in the open air — making them candidates for everyday use.

Hiebert, a researcher at the Nanotechnology Research Centre [emphasis mine] at the University of Alberta, said this means the sensors may one day run metabolic readings, cancer screenings and other tests that currently have to be done in laboratories. The sensors could also improve GPS and clock accuracy once the technology is more developed, Hiebert said.

Scientists have always believed that sensors on the nanoscale work better when they’re in a space sealed off from any air, Hiebert said. Readings taken in vacuums are much “sharper” than readings taken in regular air, which was always thought to be more useful in nanotechnology.

Four years of Hiebert’s work has found the opposite. The “duller” readings taken in the open gave the scientists a more accurate reading of what was in the air.

For the interested, there are more details in Sarkonak’s article.

For those who can read the science, here’s a link to and a citation for the paper,
