A neat ozone+UV paper pointed out by See Arr Oh
Posted in Chemjobber

Check out this really interesting Science paper highlighted by See Arr Oh, one where the authors transform cyclohexane to adipic acid (among other transformations) using ozone and 300 nm UV light. Obviously, this is a pretty neat method and one that should be highlighted to the broader scientific community.I think it's obvious to the authors that a batch reactor approach is/would be sufficient for the laboratory, but not for industrial applications to large-scale polymer needs. From the Sup...

 
Sunrise still later after Winter Solstice

Several people asked me about the odd phenomenon that in these here parts sunrise gets later each day until early January even though the days themselves get longer after the winter solstice. From EarthSky: The winter solstice always brings the shortest day to the Northern Hemisphere and the longest day to the Southern Hemisphere. But, the tardiest sunrise doesn’t coincide with the day on which the sun is above the horizon for the shortest time, least daylight hours; similarly, the latest...

SpaceX's Next Launch to Space Station Delayed Until New Year

The private spaceflight company SpaceX won't be flying its next delivery mission to the International Space Station until early 2015. SpaceX was originally expected to launch its Falcon 9 rocket carrying an uncrewed Dragon cargo ship to the station for NASA today (Dec. 19), but the launch was delayed partly due to a problem with the rocket. SpaceX is now expected to launch its fifth official mission to the orbiting outpost under a contract with NASA on Jan. 6....

 
Solvent stills and fire repercussions

Credit: Organometallics, 1996, DOI: 10.1021/om9503712 I recently came across this 2002 letter regarding still safety and lab emergency preparation from William J. Evans of the University of California, Irvine. I thought it was worth sharing again for its lessons learned: As described in the article “Putting Safety First,” my laboratory suffered major losses on July 23, 2001, as a result of a fire originating with the malfunction of a solvent still (C&EN, May 20, page 43). I heart...

Super Typhoon Shoved Car-Size Boulders Onto Philippine Beaches

Boulders the size of stretch limousines littered beaches near the city of Tacloban in the Philippines after Super Typhoon Haiyan pounded the region in November 2013. The towering stones provided a rare look at the way intense storms can demolish coastal communities, researchers said here on Tuesday (Dec. 16) at the American Geophysical Union's annual meeting. The surprising findings: freak waves that were as powerful as tsunamis shoved the enormous limestone rocks. "If we didn't know this occurr...

 
Active Sun Unleashes Massive Solar Flare

The huge solar flare registered as an X1.8-class event, one of the most powerful types of flares possible, and was captured on camera by NASA's powerful Solar Dynamics Observatory. The flare triggered a strong radio blackout for parts of Earth as it peaked Friday at 7:28 p.m. EST (0028 Dec. 20 GMT), according to an alert from the U.S. Space Weather Prediction Center overseen by NOAA. The solar flare erupted from a sunspot region classified as Active Region 2242, and more sun storms could occur f...
