12:58 PM | Getting your point across
Do the words ' Please can you prepare/deliver a presentation on x' fill you with dread? Presenting is part of many job descriptions and one which many people would rather avoid. In fact when a team a team of market researchers asked 3000 U.S. inhabitants “What are you most afraid of?” Many named more than one fear but right at the top came speaking before a group, followed by heights, insects, financial problems and deep water. (Source). An uneffective presentation can be […]

11:03 AM | Novel catalyst with two functions: hope for more cost-efficient metal-air batteries and fuel cells
Chemists have made a decisive step towards more cost-efficient regenerative fuel cells and rechargeable metal-air batteries. They developed a new type of catalyst on the basis of carbon, which can facilitate two opposite reactions: electrolysis of water and combustion of hydrogen with oxygen.

10:57 AM | Unraveling atomic-scale edge structure of nanoscale graphene islands
This is the first demonstration, combining experiment and theory, that the interaction of the carbon atoms with a metal substrate stabilizes the low coordinated carbon edge atoms. In models for the growth of graphene on metal substrates, such low coordinated atoms at the growing edge play a special role. These results, which demonstrate such stability, will play a significant role in further development of these models and will help guide future strategies to grow graphene nanostructures with […]

10:25 AM | The Chemistry of the Sun
Just about all of us will be looking for it this summer …. It makes us feel happy and eat ice-cream! It gives a tan that is the envy of our friends! In fact, at a much more fundamental level, we could not live without it … no, not the ice-cream … the sun! But [...]

6:32 AM | Nanomaterial safety: An international collaboration on in vitro testing strategies
On September 15-16, 2014, come explore ways in which Alternative Testing Strategies (ATS) may be combined to create a Weight of Evidence (WOE) or 'multiple models' approach to inform context-specific decisions about risk from exposure to novel nanoscale materials. The goal is to advance a common understanding of the state of the science, early lessons, current opportunities, and next steps for developing ATS for use in decision making for nanoscale materials.

1:17 AM | A Chempubs Hat Trick
Slow down, Guangbin!(said I, channeling my inner Dr. Freddy...)Guangbin Dong of the University of Texas-Austin has just published three papers in three different journals with Impact Factors over three. What's more - he did it all in the same week.Just think of them as buckyballsThe papers in question?"Regioselective ketone alpha-alkylation with simple olefins by dual activation"Science, published 4 July 2014; 2013 IF: 31.0"Cooperative alkylation of cyclobutanones and […]

10:14 PM | The End of Beer
It’s last call for our beer theme. And this 1908 postcard from our collections seems a good nightcap. If you’re still thirsty, we have some top-shelf options for you: Our recent beer podcast Our recent beer webcast Old beer podcast on beer and brewing with another visit to Dogfish Head Brewery What the heck, how about a final image from our collection - a brewing book with a long title, published in 1692. (Top image from the Donald F. Othmer Papers, CHF Archives, […]

5:56 PM | Spontaneous Combustion of Polyurethanes
The Polyurethane Blog has an account of a large house fire that is being blamed on spontaneous combustion of polyurethane foam insulation. My first reaction on reading this was to shout "Boy Scout" or more properly, the initials of "Boy Scout". Polyurethanes are stable polymers that don't catch on fire as any house having wood floors with a urethane finish will verify. Further, the fire had just been put out. Knowing the cause that quickly seems like something appropriate for a news reporter to […]

4:50 PM | Like music to my ears: Vox on STEM
From the comments and also via Twitter, Vox's Danielle Kurtzleben looks at the STEM shortage debate and comes away with a couple of great quotes. From STEM shortage skeptic Hal Salzman:..."STEM makes no sense as a category. What you have is science and engineering, and then you have this IT labor force," says Hal Salzman, a professor of planning and public policy at Rutgers University. "It's a non-differentiated category that makes no analytic sense." [snip]  "Frankly, if you're […]

4:43 PM | SUSS MicroTec launches ELD 300 Excimer Laser Debonder for 3D-Integration
The laser debonder can be used as a stand-alone, semi-automated system or as an integrated process module in SUSS MicroTec's XBC300 Gen2 platform. The debonding method used in the ELD300 relies on a 308nm Excimer laser to separate the glass carrier from a tape mounted thin wafer.

12:46 PM | Silicon sponge improves lithium-ion battery performance
The lithium-ion batteries that power our laptops and electric vehicles could store more energy and run longer on a single charge with the help of a sponge-like silicon material. Researchers developed the porous material to replace the graphite traditionally used in one of the battery's electrodes, as silicon has more than 10 times the energy storage capacity of graphite.

8:48 AM | Molecular motions inside the cell A paper in Science this week...
Molecular motions inside the cell A paper in Science this week describes the use of carbon nanotubes to pinpoint the movements of the living cell in fine detail, making for a really nice study in quantitative/mathematical biology. Noninvasive tracking was accomplished by imaging highly stable near-infrared luminescence of single-walled carbon nanotubes targeted to kinesin-1 motor proteins in COS-7 cells. We observed a regime of active random “stirring” that constitutes an […]

8:40 AM | A universal and rapid method for transferring nanostructures
Many nanofabrication techniques depend on creating a structure on one substrate and then transferring it via various processes onto another, desired, substrate. Often, these methods are not generally applicable as they suffer from the process-specific drawbacks, such as for instance intolerance of transferred nanostructures to chemical etchant, and the harsh thermal environment needed. A novel universal and rapid method allows transferring nanostructures with various dimensions onto diverse […]

6:06 AM | Charged devices and air travel
We have learned in the last few days that passengers boarding US-bound flights from Heathrow and Manchester (and presumably other airports) will have to show that their electronic devices are charged before being allowed to board. This policy sounds simple and possibly even sensible, but it has the potential of causing serious problems to ‘power […]

2:37 AM | A Cage-y Déjà Vu
I love finding molecular "diamonds in the rough." Especially when they look, well, a bit like diamonds!While strolling through the literature, I did a double-take at this polycyclic caged structure reported by Santiago Vázquez  (Universitat de Barcelona) and coworkers. Wow!Source: ACIEE 2014, Vasquez et. al.Spawned from a "highly pyramidalized" (nonplanar) olefin dimerization, it features three cyclobutanes, four "envelope" cyclopentanes, and four […]

8:15 PM | The quantum dance of oxygen
Under extremely high pressure conditions oxygen molecules group into quartets and give rise to a 'dance of their magnetic moments'. This results in magnetic properties never previously observed in these conditions and in theory points to the existence of a new phase of the element, called epsilon 1.
