According to Guggemos, Slavicek and Kresin, about 5-6![cite]10.1103/PhysRevLett.114.043401[/cite]. This is one of those simple ideas, which is probably quite tough to do experimentally. It involved blasting water vapour through a pinhole, adding HCl and measuring the dipole-moment induced deflection by an electric field.

ELNs (electronic laboratory notebooks) have been around for a long time in chemistry, largely of course due to the needs of the pharmaceutical industries. We did our first extensive evaluation probably at least 15 years ago, and nowadays there are many on the commercial market, with a few more coming from opensource communities. Here I thought I would bring to your attention the potential of an interesting new entrant from the open community.

A word of explanation about this test page for experimenting with JSmol. Many moons ago I posted about how to include a generated 3D molecular model in a blog post, and have used that method on many posts here ever since. It relied on Java as the underlying software (first introduced in 1996), or almost 20 years ago.

So much to do, so little time to do it. That is my excuse at least.

In the two-publisher model I proposed a post or so back, I showed an example of how data can be incorporated (transcluded) into the story narrative of a scientific article, with both that story and the data each having their own independently citable reference (using a doi for the citation). Here I take it a step further, by publishing a functional procedure in a digital repository[cite]10.6084/m9.figshare.811862[/cite] and

Because I was struggling hard with default values for cdk.interfaces fields, I did not have time to write up the Bug Squash Party report for day 3 (see also day 1 and day 2). But here it is. Day 3 Kai worked hard on getting the cdk.interfaces API cleaned up, as agreed upon earlier. Christian added a test for the RMSD calculator (see getAllAtomRMSD()), and cleaned up his code a bit.

Martin Szugat reported that a beta for BioJava 1.5 has been released. New features include: a new biojavax package with extension on the basic functionlity, such as the RichSequence.IOTools and the RichSequence object; a genetic algorithm library; features that allow manipulation of 3D structure files and objects; and non-HMM implementations of the NW and SW alignment algorithms.

Trepalin et al. published in Molecules the article A Java Chemical Structure Editor Supporting the Modular Chemical Descriptor Language (MCDL) (open access PDF). The applet is about 250kB (though the article mentions 200kB) in size and downloadable from the MCDL project on SourceForge (license: Public Domain). The article compares the applet with the JChemPaint applet and notes that their applet is much smaller.

Bling! Bling!. Mark Wielaard announced the GNU Classpath 0.92 release, with the following changes: an alternative awt peer implementation based on Escher that uses the X protocol directly. Various ImageIO providers for png, gif and bmp images. Support for reading and writing midi files and reading .au and .wav files have been added. Various tools and support classes have been added for jar, native2ascii, serialver, keytool, jarsigner.

Recently, a second beta of Java 6 was released, which triggered a patch for the Debian java-package package. It was a Bioclipse bug report today, however, which made me patch my java-package setup and install the beta. So, next thing was to try to get the CDK compile with the Java 6 beta.
