11:09 AM | Creating self-assembling nanoparticle films with a common spray gun
Researchers have developed a simple approach of applying a surface coating of thin, flat nanoplatelets using a common spray gun, such as can be purchased off-the-shelf from an art supply store, to create a surface coating in which nanoplatelets spontaneously self-assemble into 'nano-walls'. The nano-walls act as rigid barriers that prevent oxygen gas from reaching the surface, and are effective at low and high humidity levels.

12:03 AM | Conference board: US real GDP was 1.9% for 2013
Last year, I offered cash stakes ($10) for anyone who would take the over on a over/under bet for US real GDP for 2013. Well, the US Conference Board finally (today) put the magic "actual value" asterisk on Q4:That means that, likelier than not, real GDP for 2013 was up 1.9%, which means that I lost the cash bet to @Brandon_Vara. Brandon, e-mail me your address and I'll get you that ten-spot -- don't spend it all at once.It should be noted that See Arr Oh, @Lewis_Lab and @UnstableIsotope all […]

8:06 PM | The motion of the medium matters for self-assembling particles (w/video)
Earlier work assumed that the liquid medium in which certain self-assembling particles float could be treated as a placid vacuum, but a University of Pennsylvania team has shown that fluid dynamics play a crucial role in the kind and quality of the structures that can be made in this way.

3:53 PM | Finding new targets for attack on the bacterium that causes gonorrhea
April is Sexually Transmitted Disease Awareness Month and a good time to discuss Neisseria gonorrhoeae, the bacterium that causes gonorrhea. There aren’t any preventative vaccines for gonorrhea, and the bacterium is growing increasingly resistant to the antibiotics available to treat it. In a paper recently published in the journal Molecular & Cellular Proteomics, researchers describe […]

2:12 PM | Those Rich Petroleum Engineers
The Wall Street Journal yesterday had a poorly written opinion piece that was a mix of odds and ends that never really seemed to find its stride. The overall message is something of the following: petroleum engineering jobs are paying extremely well ($97,000 starting) but most schools are doing research on alternative energies and are brainwashing students not to go into petroleum engineering. Or since many schools don't offer that major, the students are also being guided away from what the […]

1:07 PM | PressPac: Toward a faster, more accurate way to diagnose stroke
Here’s an item from this week’s PressPac that we thought you’d enjoy. The PressPac features summaries of articles appearing in our peer-reviewed journals and Chemical & Engineering News. To get the entire PressPac in your inbox, email us at newsroom@acs.org.When someone suffers from a stroke, a silent countdown begins. A fast diagnosis and treatment can mean the difference between life and death. So scientists are working on a new blood test that one day could rapidly […]

12:30 PM | Chemical safety tidbits and papers, from OPRD
A tweet from Chemjobber that Organic Process Research & Development editor Trevor Laird is retiring at the end of the year made me realize that I forgot to highlight OPRD’s annual “Safety of Chemical Processes” section at the end of last year. Making up for the omission: Laird’s editorial: “There is a long way to […]

11:36 AM | A novel approach to designing drug-loaded nanoconstructs
Nanomaterials for nanomedicine and biological applications are often two-component structures - referred to as 'nanoconstructs' -consisting of a 'hard' nanoparticle core and a 'soft' shell of biomolecular ligands. Researchers have now demonstrated a nanoconstruct with enhanced in vitro efficacy. This highly loaded nanoconstruct was taken up by pancreatic cancer cells and fibrosarcoma cells at fast rates. The team found that the increased loading of Apt on AuNS also resulted in an enhanced in […]

7:04 PM | Scientific Lessons from Bread Baking
Every day chemists enter their laboratories, intent on making or studying something. For me, my daily task is to think about nanoparticles. At the end of the day the thinking process is no different than a chef working in the kitchen. Small changes in your recipe can make a huge difference. The ingredients, types, amounts, […]

6:55 PM | Weird thought for the day
There's this trope that Big Pharma doesn't develop "cures" because it will ruin the market or there's not enough incentive to do so (i.e. if they can't sell lots of pills, the market won't be big enough. Here's a good example of that thinking.)So here's Gilead's Sovaldi, which is as close to "a cure" of Hepatitis C as we've seen in a while; it sure is expensive, running about $84,000 for an entire 12-week course. Isn't this proof positive that Big Pharma will work on cures, and if it finds one, […]
