Please provide me with more information
by Andrew Sun in On The Road
First things first, I believe that it’s normal and should be highly appreciated that criticism becomes the major voices from the west as China starts to get into their eyes. This will not last long, and this is why the nation should appreciate them more. But it seems quite not the case, critiques are much less than what I have expected, and China still have been incapable to pay enough attention and consideration to the critiques that have come out. For individuals like me, they have freed........ Read more »

Liquid Mirrors
by Andrew Sun in On The Road
Liquid Mirror Telescope
The first time I heard that liquid mirrors worth studying was from a Nature‘s News & Views article. Rotating liquid that creates a parabolic surface enables human to conceive about really big telescopes that have to be built on the moon. The Nature article praised the use of ionic liquid, liquid with ’nearly zero’ vapor pressure, for liquid mirror support, because in the moon the working environment is vacuum. And it is also cold there, so the liqui........ Read more »

Latest report of adaptive synthetic surfaces
by Andrew Sun in On The Road
A dung beetle’s never too dirty. From Wikipedia.org
The biological concept of adaptation has sneaked into synthetic materials research. I was informed of this by a report on Adv. Mater.1 describing an adaptive non-adhesive surface. The report cited further for us a review on Prog. Polym. Sci.2 summing up the advances in fabricating smart surfaces by designing and synthesizing polymer brushes.
Yes. We have got encouraging advances in synthetic and fabricating skills, as evidenced by numer........ Read more »

Man-Made but Living Systems - Bio Besides Mimetics and Inspirations
by Andrew Sun in On The Road
According to Wikipedia.org which though is not often desirable, the meaning of the word biomimetics does not include the direct utilization of the functional part of living structures. We have found lotus leaves superhydrophobic. But biomimetically we didn’t directly grow lotus crops for water-repelling coatings, nor did we try to culture similar layer from lotus tissue. Rather, we got ‘inspired’ and started ‘mimicking’ the structure by purely artificial technologie........ Read more »

Snake Robot
by Andrew Sun in On The Road
A review on snake-inspired robot design was published on the IOP journal, Bioinspirations and Biomimetics, 2009 ,4, 021001. DOI: 10.1088/1748-3182/4/2/021001. The introduction paragraphs of the review described several advantages of snake-like robot compared with other types of design, which is quite interesting to read. But I did not go into the detail of the review. There are images of various design of snake robots in this paper. And this reminds me to search some videos in Youtube.com. It se........ Read more »

Is science a must for human being?
by Andrew Sun in On The Road
A Thesis published on Nature Nanotechnology1 shown that public acceptance of nanotechnology, and also generally any new technologies, depend not on the knowledgeablility of those technologies but former religious status of the public.
Strength of religious beliefs is negatively related to support for funding of nanotechnology. Religious apprehensions that developed earlier, in response to biotechnology, served as a template for reactions to nanotechnology. People for whom religion was not very ........ Read more »

No one added their test on oxidative NaH to ResearchBlogging.org?
by Andrew Sun in On The Road
I have been busy setting up the Chinese language version of ResearchBlogging.org. To explain how research blogging can be meaningful and important to the Chinese bloggers I have to provide several points and examples in an introductory webpage.
One of the best example is the recent blogging review on a NaH catalyzed oxidation reaction published on JACS1. The unexpected property of this reagent stirred up a number of synthetic chemists who repeated it and reported on their blogs. Chemist........ Read more »

Research is gray without industrial stories
by Andrew Sun in On The Road
Polymer science is more unique in its physics rather than chemistry. All reactions in various polymerization known today are not unconceivable in the scheme of organic synthesis. There is no new concept in reaction mechanisms. In contrast, the unique properties of polymer materials mainly stem from chain topology rather than detailed chemical structures, which have led the polymer physics research from Flory’s mean-field theory, in a statistical physical scheme, to de Gennes’........

Digital age or mass production age?
by Andrew Sun in On The Road
The editorial in the July 24 issue of Science1 informed me with a report by the Nanional Academies of the US, Ensuring the Integrity, Accessibility, and Stewardship of Research Data in the Digital Age. I can obtain full text of the report for free because I’m a reader from developing country. But I only had time to read the summary section.
The report gives several recommendations to different roles in the modern scientific infrastructure. Two main ideas shared by these recommenda........ Read more »
