8:08 PM | National Chemistry Week: The Chemistry of Candy
It’s currently National Chemistry Week in the US (apparently, we only get National Chemistry Week once every two years here in the UK), and the theme for this year is ‘The Sweet Side of Chemistry’. This seemed like as good an opportunity as any to look at some confectionary chemistry! In this graphic, we look at […]

3:39 PM | I've never heard of a "chemistry engineer", Mr. President.
Courtesy of Twitter user @cjt217, I see that the White House (or whichever junior deputy vice associate general special assistant to the President who wrote this letter) has invented a new term for "chemical engineers." Ah, well.(Found in the third or fourth page of the October 13 issue of C&EN.)

3:24 PM | A guest post by Chad Jones: "4 things you probably already know about grad school but really shouldn't ignore."
CJ's note: Chad wrote this for the blog back when he was defending his dissertation -- he is now Dr. Jones and is working in industry. Soon I'll be defending my dissertation and finishing up my PhD. I also have several friends who are just beginning their graduate career. It’s been a very reflective time for me. I've thought about what advice I would give to those friends just starting grad school (I've also been wondering how helpful that advice would be - after all, I read plenty […]

3:19 PM | "...however, Canadians and permanent residents will be given priority"
A reader points out the University of Alberta's interesting "Equal Opportunity" statement for its 3 tenure-track positions for assistant/associate professors in chemistry: "All qualified candidates are encouraged to apply; however, Canadians and permanent residents will be given priority. If suitable Canadian citizens or permanent residents cannot be found, other individuals will be considered. The University of Alberta hires on the basis of merit. We are committed to the principle of […]

3:03 PM | Daily Pump Trap: 10/21/14 edition
Not too many industrial positions of late (last 1-2 weeks or so) at C&EN Jobs:Lake Charles, LA: Rain Cii is looking for a B.S. chemist with 5 years experience for a "lab superintendent." (What a grand title!) San Francisco, CA: Oh, man, you've heard of "method" products, right? Check out this description for a "green chef director":Reporting to the Sr. Director of Formulation, a Green Chef is part chemist, part engineer, part innovator and part git-r-done. The Green Chef role is to […]

2:48 PM | Ivory Filter Flask: 10/21/14 edition
A few of the recent academically-related positions posted on C&EN Jobs:New York, NY: NYU is looking for an assistant professor of physical, biophysical, or inorganic chemistry as part of its Laboratory for Molecular Nanoscience. (I find all of these tiny institutes kind of funny -- what are they supposed to accomplish?)Ann Arbor, MI: The University of Michigan College of Pharmacy's Department of Medicinal Chemistry is searching for an associate professor to join its department.Durham, […]

1:38 PM | Nobel 2014: What makes super-resolution microscopy so super?
The awarding of the 2014 Nobel Prize in Chemistry to Dr.s Betzig, Hell, and Moerner (my former research mentor) is a tremendous event! It is almost as tremendous as their scientific targets are tiny: they were awarded the prize for super-resolution fluorescence microscopy, a technique for using a light microscope to examine objects as small […]

1:19 PM | Carbon nanotubes for the next generation of electronics and photovoltaics
Researchers have developed a method to separate nanomaterials by size, therefore providing a consistency in properties otherwise not available. Moreover, the solution came straight from the life sciences - biochemistry, in fact.

12:38 PM | The Hangover Continues: the morning after the night before
Even a few hours’ sleep are not enough to erase all the alcohol consumed the night before, and if you ever experienced anything like this before, you probably woke up with a massive headache and dry mouth, not to mention an inability to even consider eating anything. In addition, a confused and dazed brain has [...]

10:51 AM | Ultra-stretchable silicon for flexible electronics (w/video)
Researchers have demonstrated ultra-stretchability in monolithic single-crystal silicon. The design is based on an all silicon-based network of hexagonal islands connected through spiral springs. The resulting single-spiral structures can be stretched to a ratio more than 1000%, while remaining below a 1.2% strain. Moreover, these network structures have demonstrated area expansions as high as 30 folds in arrays. This method could provide ultra-stretchable and adaptable electronic systems for […]

7:28 PM | Restoring order - A spin Hall effect without all the fuss
Scientists have developed a model for what happens when ultracold atomic spins are trapped in an optical lattice structure with a 'double-valley' feature, where the repeating unit resembles the letter W. This new theory result opens up a novel path for generating what?s known as the spin Hall effect, an important example of spin-transport.

6:03 PM | My challenge to those who believe in (s)low economic growth
"A more sustainable economy" has long been a theme of Rudy Baum's C&EN editorials -- the latest column in this week's C&EN is a rerun of a column from 2004*:I will review “Red Sky at Morning” in an upcoming issue of C&EN. Here, I want to take up one issue that Speth returns to repeatedly in his book: For our global economy to become a sustainable economy will require a fundamental shift in the economic paradigm that governs human activity today. Specifically, Speth […]

5:46 PM | Something for California taxpayers to grouse about
I have been extremely remiss in noting that Kim Christensen of the Los Angeles Times has revealed UCLA spent over 4.4 million dollars defending Professor Patrick Harran from felony charges in relation to the death of Sheharbano (Sheri) Sangji in 2009 due to an accident in his laboratories with tert-butyl lithium:After UCLA chemistry professor Patrick Harran walked out of court in June, his lawyers issued a news release hailing the "first-of-its-kind" deal that all but freed him from […]
