China’s nanotechnology rise

Eric Berger’s blog, SciGuy, recently highlighted some data about the number of nanotechnology/nanoscience articles published by Chinese researchers. You can see the entry and the table listing the world’s most prolific (overwhelmingly Chinese)  nanotech authors here. It’s interesting to contrast this data with a Nature Nanotechnology editorial from June 2008 where they had tables listing the countries with the most published nanotech articles and the most frequently cited articles. At the time, I thought China was under-represented although I don’t state it explicitly in my comments here.

Berger was inspired to write his commentary after seeing Eric Drexler’s posting on the topic (Oct. 30, 2009) but I’m directing you to Drexler’s followup comments where he provides some context for better understanding the statistics and cites sources that discuss the matter at more length.

The general consensus seems to be that some of China’s nanotech research is world class and the quality of majority of the research papers is either very good or improving rapidly.

There’s also this from the Center for Nanotechnology in Society University of California Santa Barbara (CNS-UCSB) paper, Chinese Nanotechnology Publications (scroll down the page to IRG 4-3 to read the full abstract),

China’s top-down and government-centered approach toward science and technology policy is succeeding in driving academic-publications output. By 2005 China had equaled or possibly surpassed the U.S. in terms of total output for academic/peer-reviewed publications, with a substantial increase in publication rate from around 2003. … We examined US and Chinese nanotechnology trends in the scientific literature and found that Chinese nanotechnology output is growing rapidly and will likely [outperform?] US output in terms of quality as well as quantity within a decade or less (Appelbaum & Parker 2008).

I include this portion of the abstract because  the phrase, “China’s top-down and government-centered approach to science and technology” points to something that’s not explicitly noted in the abstract, cultural and political climate. Nor was it noted in Bruce Alberts’ speech (in my Is science superior? posting) and as Inkbat noted in her comments to that posting. (My apologies to Mr. Alberts if he did make those points, unfortunately his speech is not available on the conference website so I’m depending on attendee reports.)

It’s a tricky matter trying to compare countries. China has more people and presumably more scientists than anyone else, all of which should result in more published articles if the area of research is supported by policy.

One of the issues for Canada is that we have a relatively small population and consequently fewer scientists. I commented on some work done by M. Fatih Yegul (in June 2008) where he contextualizes the number of Canadian articles published on nanotechnology and our focus on collaboration. Here’s part 2 of the series where I mentioned the numbers. (I did not post much material from Yegul’s paper as he was about to present it an international conference and it had yet to be published. I just checked today [Nov.4.09] and cannot confirm publication.)  My comments from part 3 of the series,

It’s all pretty interesting including the suggestion (based on a study that showed Canada as ranking 6th in numbers of science articles published from 1995-2005) that Canada is performing below its own average with regard to nanotechnology research.

I don’t know if the situation in Canada has changed since Yegul wrote and presented his paper but I strongly suspect it has not.

As for the roles that culture, social mores, history, and political environment play, I just can’t manage more than a mention in this posting in an effort to acknowledge their importance.

Do check out Rob Annan’s posting today (Nov. 4, 2009) about Science and Innovation in the wake of the 2009 Canadian Science Policy Conference.

Numbers of published nano articles, China, and Canada’s nanotech

Nature Nanotechnology published an editorial in their June 2008 issue about which countries have published the most articles and which are most often cited. In examining their own journal and a couple studies, they found that the US has published the most with China coming up quickly to overtake US output in the near future.

How do you attribute an article to a country? In these studies, they looked at the lead author’s affiliation. For number freaks, Nature Nanotechnology published 94 letters and 55 articles with 47.6% of the authors being located in the US, followed by 8% from the UK, 7.4% from Japan and 6.7% from Germany. I guess the rest of us make up the other 30% or so. The figures about the China’s articles come from other studies that the editorial cites. (I’d link to Nature Nanotech but the journal’s latest issues are behind a paywall. They’ll let you sniff some of the cheese but you won’t be able to take a bite for at least a year.)

One point they do make is that the Chinese articles aren’t cited as often as US articles or even Japanese articles (China’s output has been higher than Japan’s since 1990). All of which is interesting since, citations are one measure of quality and/or influence. I think it’s safe to assume that  they’re talking about articles that were written in English so we’re not looking at language issues. Still, I can think of at least one reason why work from China might not be cited as often: geopolitical tensions.

Here’s another suggestion: where are the Chinese authors getting published? If your work isn’t being published in journals that other interested parties are reading, how are you going to get cited? (Brief related story) I do research for a psychiatrist (he specializes in pain management) who’s interested in checking out some of the latest research on morphine. I have two entirely separate research tracks each with their own specialized vocabularies and specialty-specific journals. If I use the wrong words, I won’t find the other research material. (Back to the nano) So now there are two other possible problems. Researchers casually thumbing through Nature Nanotechnology are not going to see many articles from China (as per the June 2008 editorial) and, if Chinese researchers are using the vocabulary differently, standard keyword research strategies aren’t going to  lead you to their work.

As for the Canadian nanotechnology scene, we don’t seem to be on the radar for either Nature Nanotechnology or the two studies they cited. I’m a little curious about that since there was a presenter at the 2008 Cascadia Nanotechnology Symposium in March who focussed on numbers of articles published by Canadian nano researchers. As I recall, he indicated that our numbers are pretty healthy.  I’m trying to track that info. down but I can’t find M. Fatih Yegul’s (University of Waterloo) presentation on the symposium website or any other published version of his information.
