1:27 PM | A Mixing Demonstration using non-Newtonian Blue Maize Flour Suspension
The Journal of Chemical Education has an article on mixing in non-Newtonain suspsensions that is visually appealing. They use blue maize flour, a material whose color is pH sensitive (I didn't know that). It goes through the color sequence shown below.Being a flour suspension, the material is non-Newtonian with a viscosity that changes with shear rate. But even more intriguing is that the viscosity of flour/water suspensions is pH sensitive. So as you might expect, the demonstration/experiment […]

10:38 AM | New material steals oxygen from air
Researchers have synthesized crystalline materials that can bind and store oxygen in high concentrations. Just one spoon of the substance is enough to absorb all the oxygen in a room. The stored oxygen can be released again when and where it is needed.

8:02 AM | At the interface of math and science
In popular culture, mathematics is often deemed inaccessible or esoteric. Yet in the modern world, it plays an ever more important role in our daily lives and a decisive role in the discovery and development of new ideas - often behind the scenes.

6:16 AM | Not Your Daddy’s Sunblock – Why Thick, White Sunblock is a Thing of the Past
As a child, I spent many summer days at the beach in southern California. I remember playing in the surf, collecting shells, watching sea lions, and seeing the white noses of the lifeguards. In those days, lifeguards smeared thick, white zinc oxide paste on their noses to protect themselves from getting sunburned When my kids […]

Fortune magazine cover designed by Arthur Lidov, depicting Maxwell’s thermodynamic surface of an “imaginary substance” similar to (though not quite) water based on J. W. Gibbs's work, alongside Gibbs's formula for the phase rule, bottom left To describe a closed, homogeneous system — that is one of constant composition, such as an ideal gas — we need two parameters of state (e.g. T and p). For a heterogeneous system in equilibrium, […]

7:42 PM | CMOs and chemistry
Finally, from this week's C&EN, an interesting set of quotes from Rick Mullin's interviews with a number of CMO leaders. Here's the CEO of Hovione, a Portugal-based API manufacturer on what he thinks companies need: The contract manufacturing business is moving into a new phase, according to Villax, one that has little to do with the hardware. “Now, you simply can’t just buy the differentiator,” he says. “Success is the result of experience and accumulated […]

7:40 PM | Carbon nanotubes and the environment
This paper caught my eye or rather the report in Chemistry World did (both are open access). It is a study conducted by Ferguson etal discussing the fate of single walled nanotubes in the environment. Now I am the first to admit that I don’t know much about this, I am aware of the advances in the synthesis of […]

6:45 PM | Anyone want to explain the chemistry of diapers?
This week's C&EN also brings us a rebuttal to a recent Newscripts column on diapers:...Newscripts recently waxed enthusiastic about Charlie’s Soap, “a laundry detergent brand that is popular among folks concerned about laundry residues” (C&EN, July 7, page 40). Charlie’s Soap is good, we are told, because it contains fewer ingredients than other detergents. It seems to contain only soap and soda ash. Charlie’s Soap might actually work—if you […]

5:11 PM | This week's C&EN
Lots of interesting stories this week:Prof. Carolyn Bertozzi is the editor-in-chief of ACS' new open access journal. (by Linda Wang) It'll be fascinating to see where the journal goes and which papers end up there... Mitch Jacoby has an interesting article about chemical companies participating in science industrially-oriented master's programs. I think that the key will be: will the participating companies be willing to eat their own dog food? 20 chemists worth following on […]

2:08 PM | Ocean Plastic - The Truth and More Hype
I ran across a couple of articles this weekend regarding ocean plastics that are worth a read. The first is from Grist.org, entitled 8 Things You Should Know About Plastic in the Ocean. The amazing aspect of the article is that it gets it right. Or at least the text is correct. The pictures tell another story. They are still of macroscopic objects on beaches or in the water. But the text is correct. In brief, there is a lot of plastic particles out there, but we don't know how much, we can't […]

12:36 PM | Scientists improve nanowire batteries with homebuilt imaging analysis
In a rare case of having their cake and eating it too, scientists have developed a toolset that allows them to explore the complex interior of tiny, multi-layered batteries they devised. It provides insight into the batteries' performance without destroying them.

9:38 AM | Researchers create 'tractor beams' in the lab
Tractor beam technology, if it were to exist, would be based on waves that go in the opposite direction, converging from out in space onto the point of origin. Researchers now showed that the idea may not be all science fiction.

5:40 AM | Determining Temperature Boundary of the A1→(A1+B2) Phase Transformation in the Copper-55 at% Palladium Alloy Subjected to Severe Plastic Deformation
The changes in phase state, electrical properties and microhardness of copper-55 at% palladium alloy samples with different initial states (as-quenched and deformed via severe plastic deformation (SPD)) were studied during isothermal annealing. Ordered B2-phase formation in the disordered (A1) matrix was found to occur at a significantly higher temperature than is indicated in the generally accepted phase diagram of the Cu-Pd system. Corresponding electrical resistivity is also lower than […]

1:17 AM | Scientific papers, funding, commercial applicability and relevance: scientists have mixed ...
There are a number of problems that seem to be looming, one of which is the climatic effects of the so-called greenhouse gases. Science should be able to address such problems, but the question arises when a discovery is made is, is this a solution to the designated problem, could it be a solution to the designated problem if some further problems can be overcome, or is it simply an interesting observation but essentially irrelevant in terms of solving any of our problems? With the problem of […]
