12:20 PM | Carbon nanotube catalyst may rival cost-prohibitive platinum for hydrogen production
The new technology is a novel catalyst that performs almost as well as cost-prohibitive platinum for so-called electrolysis reactions, which use electric currents to split water molecules into hydrogen and oxygen. The technology is also far more efficient than less-expensive catalysts investigated to-date.

10:20 AM | Nanotechnology fabrication - from stronger Kevlar to better biology
Place two large, sturdy logs in a streambed, and they will help guide the water in a par­tic­ular direc­tion. But imagine if the water started mim­ic­king the rigidity of the logs in addi­tion to flowing along them. That's essen­tially what hap­pens in a directed assembly method devel­oped by a researcher at Northeastern University.

7:50 AM | I need your input please
In an ideal world the support we give you will provide the tools you need to manage your career; to enable you  to find the job you really love to do, the one which makes you bounce out of bed in the morning. Unfortunately it's not always an ideal world and many members we speak to are feeling overwhelmed in their career management. Whilst we have developed a number of ways to help you manage your career, we can always improve so I have a question for you: How can we help you manage […]

4:18 AM | Conceptualizing small-molecule syntheses
Researchers from the University of Illinois at Urbana-Champaign recently reported a premise for the systematic synthesis of an unprecedented number of polyene natural product targets. Using the well-known Suzuki-Miyaura cross-coupling reaction, Martin Burke’s group linked together common polyene motifs within N-methyliminodiacetic acid (MIDA) boronate building blocks. They report a series of twelve such stereochemically-defined MIDA boronates which can […]

2:01 AM | Planetary formation update – May-June
My theory of planetary formation differs from the standard theory in three ways. The first two are that the standard theory has no mechanism to reach the initial position that it assumes, which is an even distribution of planetesimals (asteroid-sized bodies) with respect to distance from the star. (There is a lowering of concentration due to greater circumference as r increases.) My theory requires accretion to be due to chemical means (which includes physical chemistry), which means the […]

9:43 PM | Researchers discover an all-boron fullerene
Researchers have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It's the first experimental evidence that a boron cage structure - previously only a matter of speculation - does indeed exist.

3:47 AM | Richard Feynman, sexism and changing perceptions of a scientific icon
I fell in love with Richard Feynman when I was in middle school. That is when I discovered "Surely you're joking Mr. Feynman" in my dad's bookshelf. For the first few hours I laughed till tears were rolling out of my eyes. This was not science, it was choice entertainment of the highest order. Whether he was fixing radios by "thinking", blowing up the physics lab at Princeton to test his thoughts on a water sprinkler experiment or cracking top-secret safes at Los Alamos for pure amusement, […]

2:48 AM | Confessions of a Champion: Where are the American Kennel Club’s Priorities?
Atop the American Kennel Club's website reads an adage phrased in uncontested truth - "We're more than champion dogs. We're the dog's champion." Certainly, their list of recognized breeds contains some distinguished-looking dogs - the Shiba Inu, with its lion-like coat of gold, or the Papillon, with ears like flightless wings. They represent every extreme of physicality, in size, shape, and shagginess. They boast twisted tails and corded coats, in colors from russet red to timberwolf grey. But […]

2:30 PM | A House Fire due to Spontaneous Combustion of Polyurethanes? - Not so Fast
This is just a quick followup to a post from a few days ago in which I wrote about spontaneous combustion of polyurethanes leading to a house fire. You may recall that I was initially skeptical of concept in general, but have come around to accepting it.But that might not be the case with the house fire that first came to my attention. The Urethane Blog is now reporting that investigators are looking at other causes for the fire. (The headline states that spontaneous combustion is ruled out as […]

2:12 PM | Cash Flow in Small Businesses
I was quite surprised this morning to see the local paper reporting that Obama wants companies to pay their suppliers faster, mostly because this doesn't strike me as anything that a president should be getting involved in.Having worked for small companies for more than a decade, I highly appreciate the problems they have in getting paid and how that impacts their cash flow. In my last job, our standard contract was 30-days net, but we had many large clients that would routinely change that to […]

10:37 AM | Use of Sodium Chlorate as Weed Killer
With the formula NClO3, sodium chlorate forms white crystals highly hygroscopic and easily dissolved in water. It’s stable at room temperature, but it decomposes at high temperatures (above 300 degree Celsius) to generate sodium chloride (NaCl) and free oxygen. Industrially, this compound is produced via an electrolysis reaction involving sodium chloride and water in hot [...]
