10:10 AM | 5 Uses of Sodium Hypochlorite
The most common use for Sodium chlorite (NaClO) may be as bleach, but it is certainly not the only one. Other examples include cleaning water and disinfection for the treatment of eczema, to name just a few.  How is it produced? In 1789, Claude Berthollet was the first to synthesise potassium chloride (KClO) by mixing potash [...]

2:05 AM | A response to recent events
The re-post of my Feynman post on SciAm and the note attached to it have led me to write this response. Several readers have asked me what happened, so I will endeavor to clear the air and provide what I consider to be a complete story from my perspective. Folks are welcome to comment and criticize any of the actors involved in the story. One reason I am writing this is because I think it raises several issues that are at the heart of blogging in the age of social media and under the […]

6:05 PM | Cognitive dissonance
I subscribe to the American Chemistry Council's daily newsletter, because why not try to learn what the CEOs of industrial chemistry are thinking? The "Leadership and Management" section is always, always, always good for a laugh and today is no exception.

2:32 PM | Directly visualizing hydrogen bonds
Using a newly developed, ultrafast femtosecond infrared light source, chemists have been able to directly visualize the coordinated vibrations between hydrogen-bonded molecules - the first time this sort of chemical interaction, which is found in nature everywhere at the molecular level, has been directly visualized.

2:27 PM | Thermoelectric nanomaterials for future green tech devices
Thermoelectric devices, which convert heat to electricity and vice versa, can harness that wasted heat, and possibly provide the green tech energy efficiency that's needed for a sustainable future. A new study shows how porous substances can act as thermoelectric materials - pointing the way for engineering the use of such materials in thermoelectric devices of the future.

1:44 PM | An Unlikely Combination: Thiol-Ene Chemistry and Isocyanate-Free Polyurethanes
Long-time readers of this blog may recall that I spent a good deal of time with my previous employer working with thiol-ene chemistry. I really loved working with that chemistry - it was very fast and versatile, although my wife never enjoyed the experience of handling my cloths at the end of the day. Upon changing jobs a year and a half ago, I've set those malodorous chemicals aside and moved on to other monomers. These new monomers are apparently lightly scented, but I always question why […]

12:54 PM | Researchers develop an extremely simple procedure to obtain nanosized graphenes (w/video)
This method is based on the reactivity of a group of molecules named arynes, which can act as 'molecular glue' to paste graphene fragments together. The clover-shaped nanographenes obtained in this research were deposited on ultrathin insulating films, and imaged with atomic resolution by atomic force microscopy.

12:45 PM | Novel method for growing high-quality oxide thin films on a glass substrate
Researchers succeeded in growing thin film crystals consisting of highly oriented crystal grains, which were as large as a few micrometers or more, by coating a glass substrate with oxide sheets of about one nanometer in thickness, called oxide nanosheets, and using these nanocrystals as seed crystals in solid phase crystallization.

9:24 AM | Is it Time for Fake Tan?
On one of our recent blogs, we looked at the chemistry of the sun. However, we all know how too much of it can be dangerous, which means a natural tan without the aid of any products is totally out of the question. If you’re looking for “the look” (more importantly without risking your health), [...]

8:31 AM | Science journalists pen Copenhagen Declaration on nanotechnology
The science debate of the European Science Journalists EUSJA revealed many severe misunderstandings and a profound lack of knowledge about nanotechnology, two decades after the topic first emerged. More detailed information and more dialogue is necessary, in particular a broader array of inclusive, participative and collaborative formats, above all in the early phases of research.

7:34 AM | Photorealistic plasmonic printing with aluminum nanostructures
Aluminum has gained interest in the field of nanoplasmonics not only because it is abundant and costs a fraction of gold or silver, but also because it allows field-enhancement effects into the ultraviolet. However, it has broader resonances than silver and gold, and forms an oxide layer. Both these effects are undesirable in applications such as biosensing, in which signal strengths are reduced in the presence of resistive losses and oxide barriers. However, color printing based on the plasmon […]

10:09 PM | Janet Stemwedel and "The Book of Job"
Via a random Twitter clicking, a wonderful tribute by Janet Stemwedel in 2012 to Dr. James Lu Valle, during a key point in her life as a graduate student at UCLA: ...Back in the spring and autumn of 1992, I was a chemistry graduate student starting to believe that I might actually get enough of my experiments to work to get my Ph.D. As such, I did what senior graduate students in my department were supposed to do: I began preparing myself to interview with employers who came to my campus […]

7:26 PM | Researchers find nanoscale revolution biomotors in many bacteria and viruses
Researchers reported the discovery of a new class of biomotor, unique in that it uses a 'revolution without rotation' mechanism. Rotation is the turning of an object around its own axle, as the Earth does every 24 hours. Revolution is the turning of an object around a second object, as the Earth does around the sun.
