5:18 AM | Nanotechnology engineers develop disposable lung infection detector
Imagine a low-cost, disposable breath analysis device that a person with cystic fibrosis could use at home along with a smartphone to immediately detect a lung infection, much like the device police use to gauge a driver's blood alcohol level.

3:08 AM | David Greenglass and Robert Oppenheimer: A lesson from history
David Greenglass and Robert Oppenheimer(Images: NYT and NDTV)The name of David Greenglass must have almost completely faded from memory for people of my generation. Greenglass himself probably wanted his name to fade from all of history, although history is seldom so kind. The fact remains that not only did he spy for the Soviet Union on the Manhattan Project but he also likely betrayed his sister and sent her to the electric chair.Greenglass who died quietly today at age 92 in a nursing home […]

12:30 AM | Measuring Water Solubility of Platinum Group Metal Containing Substances
The water solubility of 22 platinum group metal (pgm) containing substances was evaluated to provide useful data for regulatory compliance and to aid assessment of their environmental impact. The flask method from OECD Guideline 105 (1) for the testing of chemicals (water solubility) was used to test each material. For substances that could not be isolated as pure solids, a simplified water solubility test was carried out. The results provide reliable data on solubility previously unavailable […]

6:34 PM | Future computers could be built from magnetic 'tornadoes'
Magnetic materials form the basis of most hard disc drives as they are able to store data. Engineers have been investigating whether they could also be used to perform calculations, and so take on the role of a computer's central processing unit (CPU).

6:27 PM | The Chemistry of Glow Sticks
Everyone’s familiar with glow sticks, but it’s likely that fewer are familiar with the chemistry behind their glow. You may have wondered what happens when you snap a glow stick to activate it; by doing this, you’re actually kicking off a chemical process that eventually leads to the production of the coloured light. But how does […]

4:19 PM | Who's the world's greatest living chemist?
Roald Hoffmann: My candidate for title of 'world's greatest living chemist'Since we have been making lists of Nobel Prize candidates for the last few weeks and since we already have a few lists of "greatest chemist in history", I thought I would ask for a different kind of selection: Who would be a candidate for the title of 'greatest living chemist'?Now I would be the first one to admit that any kind of 'greatest' list is always fuzzy and subjective, partly because the meaning of 'greatest' […]

3:20 PM | Is the ACS ready for a Cannabis Chemistry division?
Via LinkedIn, a fascinating petition:This is a petition to form a professional division within the membership of the American Chemical Society. The title of division shall be Cannabis Chemists. One might think that this is too specific of a designation for a separate professional division. I would however argue that it is a rapidly expanding profession and that we face many issues specific to the industry. As the medical marijuana and recreational cannabis industry grows it promises to […]

2:57 PM | "Of course I own this facility!"
I've linked the Tremblay article below in the links post for the week, but I cannot resist this quote from the article:Censere’s Utley, though, is not surprised. In his 25 years as a financial investigator in China, he has come across all sorts of scams. One company that Utley and his team of forensic accountants was hired to investigate had 12 different sets of accounts that management used to show different groups. One indication of the large scale of fraud is that an open market […]

2:54 PM | When will C&EN go digital-only? I shudder to think
From this week's C&EN, a funny letter: Yes, “moving to an exclusively digital format” would preserve natural resources, as Chris Erickson lucidly explained in his letter to the editor (C&EN, July 28, page 4). But I beg ACS to retain the print version of Chemical & Engineering News. It is, frankly, the principal benefit I derive from membership. Receiving C&EN in my otherwise crowded-with-catalogs mailbox is a weekly delight. I can read it anywhere. It gives […]

2:46 PM | This week's C&EN
Sorry for the delay. Long day yesterday. Good stuff in this week's C&EN:Fascinating story by Britt Erickson on farmers suing Syngenta for getting GMO crop protein in their non-GMO crops. Apparently, China has not approved this particular protein for sale and if your crops are contaminated with it, too bad!Thoroughly enjoyed this story by Jean-François Tremblay on short-sellers having a field day in China taking down stocks of companies that are most likely fraudulent. A profile […]

1:55 PM | Yet more activist investors thinking they can run a chemical business
I've been writing a fair amount this past year about Daniel Loeb and his efforts as an activist investor to tell Dow Chemical's CEO how to run his business (1, 2, 3, and 4).Since Dow is doing so well (no doubt as a direct result of Loeb's guidance (/sarcasm_off), Loeb is looking for a new place to produce similar results, now setting his sights oversee on DSM. He wants DSM to sell off the low profit plastics business and focus exclusively on the baby food and nutrition supplements business […]

Histone proteins are decorated by a variety of protein posttranslational modifications called histone marks that modulate chromatin structure and function, contributing to the cellular gene expression program. This SnapShot summarizes the reported human, mouse, and rat histone marks, including recently identified lysine acylation marks. In a SnapShot (short magazine feature) in Cell this week, Huang et al. provide this map of sorts, charting the landscape of […]

11:11 AM | “In Vino Veritas” … or the Chemistry of Hangovers!
After a glass of Champagne, a whisky and a couple of cocktails, we’re probably starting to feel a little “happier”. Cheeks are rosy, inhibitions are coming down and euphoria levels are high! This is the start of what doctors call alcohol intoxication, and happens when alcohol consumption overwhelms the liver and this compound starts accumulating [...]

7:40 AM | Graphene laminate drastically changes heat conduction of plastic materials
Graphene laminate - multilayer stacks of graphene layers piled on top of each other - is a promising material for thermal coating applications. Researchers have investigated thermal conductivity of graphene laminate films deposited on PET substrates. They found that the compressed laminates have higher thermal conductivity for the same average flake size owing to better flake alignment. This shows a possibility of up to 600-times enhancement of the thermal conductivity of plastic materials by […]

6:22 AM | You don't need that big expensive magnet to do NMR!!!
As chemists we often focus on parameters like chemical shift, scalar coupling and integrals that can be measured in an NMR spectrum and interpreted to understand qualitative and quantitative information about molecules.  There are applications where these parameters are less important and the longitudinal (T1) and transverse (T2) relaxation time constants and/or the self-diffusion coefficient (D) are critical.  A lot of these applications do not involve the types of samples […]

7:21 PM | The demise of ScienceOnline
So it seems that the pioneering science communication conference Science Online is no more. It's a sad piece of news, especially since I attended the conference twice and had registered to attend it again in Atlanta next year.The news is sad but it's not entirely surprising; in fact I got the first whiff that something might be wrong when I was getting emails asking me to encourage others to register even one week after registration opened (usually registration sells out in minutes). The events […]
