Nano & wastewater : volumetry in biomedical publications since 2000


This chart was built by searching PubMed for publications mentionning the prefix nano and wastewater topic in their title or abstract.

Nano & French university patents : Université Claude Bernard (Lyon) ranks 1st


This chart was built by searching the Espacenet database for patents

1) mentionning the prefix “nano” in their title or abstract

2) mentionning “univ”, the [FR] country code, and the name of the university in the “applicant” field

3) without any restriction of publication year

Only the top 10 most visible French universities according to these criteria are presented in the chart (NB : total number of patents is much lower than for US universities)

Nano & US university patents : strong Californian leadership, Rice University comes second


This chart was built by searching the Espacenet database for patents

1) mentionning the prefix “nano” in their title or abstract

2) mentionning “univ”, the [US] country code, and the name of the university in the “applicant” field

3) without any restriction of publication year

Only the top 10 most visible US universities according to these criteria are presented in the chart.

University nanotechnology patents : China, USA and Korea most productive countries


This chart was built by searching the Espacenet database for patents

2) mentionning “univ” and the country code in the “applicant” field

3) without any restriction of publication year

Only the top 10 most visible countries according to these criteria are presented in the chart.

USA risk losing global leadership in nanotech


According to a new report from Lux Research, “In terms of sheer volume, The U.S. dominated the rest of the world in nanotech funding and new patents last year (…). But (…) countries such as China and Russia launched new challenges to U.S. dominance in 2009, while smaller players such as Japan, Germany and South Korea surpassed the United States in terms of commercializing nanotechnology and products.” (press release)

Nanoparticles risks vs benefits : the blogosphere trend


These charts were built by searching Google advanced blog search for posts respectively quoting nanoparticles (1st chart) ;  nanoparticles and risks / nanoparticles and benefits (2nd chart). The online mediatization of nanoparticles in the blogosphere appears to explode in 2005 and strongly increase from year to year ever since, with more visibility for the associated risks than benefits.

It is not very clear why 2005 would be the turning point, nevertheless it is interesting to confront these charts to a timeline of nanotechnology policy and regulation in Canada, Australia, the EU, the UK and the USA.
