9:29 PM | Migrating to CDK 1.5: SSSR and two other ring sets
I arrived a bit earlier at the year 1 eNanoMapper meeting so that I could sit down with Nina Jealiazkova to work on migrating AMBIT2 to CDK 1.5. One of the big new things is the detection of ring systems, which John gave a major overhaul. Part of that is that the SSSRFinder is now retired into the legacy model. Myself, I haven't even gone into all the new goodies of this, but one of the things we needed to look at, is how to replace the use the SSSRFinder use for finding the SSSR set. So, I […]

9:18 AM | How to calculate wind chill
Wind-chill, windchill, wind chill factor, wind chill index is an estimate of how cold you will feel at a given air temperature when there is a wind blowing. It is a popular tool used by weather presenters to make you feel worse about going outside when it’s cold and windy! Seriously, if, for example, the […]How to calculate wind chill is a post from the science blog of science journalist, photographer and musician David Bradley Subscribe to our Email Newsletter

8:24 AM | Assembling nanoparticles into 3D structures with one microdroplet
Existing fabrication techniques for 3D microstructures usually suffer from complicated equipment, time-consuming processes, and insufficient controllability on precise structures. Constructing controllable 3D self-assembly microstructure in a simple and convenient way is still a challenge. In new work, researchers propose a facile strategy to directly assemble nanoparticles into controllable 3D structures from one microdroplet based on 0D hydrophilic pinning pattern.

4:40 PM | Worthwhile safety warning on nitrogen in plant-scale Grignard quenches
From th'Gaussling:...Performing a “kill reaction” or a quench of a reactive metal at the bench or at scale is always problematic and requires the skill and close attention of the process chemists and operators. I guess what I’d like to pass on is that nitrogen is not an innocent spectator in the presence of finely divided, activated magnesium. Humid nitrogen can support a combustion reaction to produce nitrided magnesium once preheated to an onset temperature. If you mean […]
