Albert Folch from Lab on a Chip released a cool artsy project this past Friday that the journal has been working on. Defined bluntly, the project is a collaborative flickr account to share the pictures of your science. The general theme is miniaturization, and of course dyed water on chips.

*Welcome Pipeline readers! No really, if you have a dusty bottle of sparteine, we’ll probably take it
Our lab uses a lot of (-)-sparteine in enantioselective aldol additions, so we tend to buy large bottles which last us a while. As such, we haven’t had to order (-)-sparteine in a while. But our bottle [...]Puzzling polymorphs
Updated: 2010-06-08 05:47:44Polymorphism is a common and sorta crazy issue in pharmaceutical process chemistry. Basically put, a drug molecule in the solid state can have multiple crystal forms. Different impurity profiles and different crystallization techniques (solvents, heating/cooling rates) can produce different polymorphs, which can have wildly different physical properties and bioavailabilities. A famous story of troublesome polymorphism [...]Science as Art
Updated: 2010-06-04 01:31:15Princeton University’s Art of Science contest has produced a gallery of pretty spectacular images of science in action. This is the fourth Art of Science competition hosted by Princeton University. The 2010 competition drew more than 115 submissions from 20 departments. The exhibit includes work by undergraduates, faculty, research staff, graduate students, and alumni. The 45 works [...]Nature Has a Graphical Abstracts Problem
Updated: 2010-05-26 06:53:21Or I should say, it had a problem. The most annoying thing about Nature journals, not including Nature Chemistry, is they do not have a graphical abstract associated with their rss feed or even in their Table of Contents. However, I made a hack to view Nature with an associated graphical abstract over at ChemFeeds. link: [...]Annual (2010) O Levels Chemistry June Holidays Intensive Revision Bootcamp

Hi Students (and Parents),
With GCE ‘O’ Level Examinations coming in less than 5 months time, how many of you are prepared for it?
Not sure? Take a look at your Mid-Year Examination Paper + Sec 3 End-of Year Paper + Continual Assessment Tests recently. If you are not scoring B3 and above, it might shows that [...]A chip for counting cells

In Chemical Bonding chapter of Basic Chemistry Syllabus (O Levels, etc), you have learned about the term Allotropes as well as Macromolecules.
To be more exact, you learned that Allotropes = Compounds with the same element with different structure.
The two examples you learned are Diamond and Graphite, which [...]Chemistry Phenomenon: Thermit Process to weld steel railway lines together

Books, Books, Books! They are something we cannot do without – be it in leisure (novels, magazines, etc), academic (school textbooks, revision books, workbooks, etc) or self-improvement (motivation, self-development, etc).
Even with the advance of technology, the kindle, the ipad, the macbook, the netbook, etc – we all still need and want books.
