http://www.rheothing.com/2008/07/accelerated-aging-getting-bad-data-even.html
Everything flows, but only the macromolecules are worth the time. Monday, July 14, 2008. Accelerated Aging - Getting Bad Data Even Faster - 1st in a Series. I say "could" for good reason. This testing is far more complicated than it appears (my employer does lots work for people that don't do their accelerate aging properly). All the pitfalls are too numerous to mention, but one for starters:. 1) Acceleration of the wrong failure mechanism. Subscribe to: Post Comments (Atom). Subscribe in a reader. 25 ye...

It's the Rheo Thing: Polydopamine
http://www.rheothing.com/2015/07/polydopamine.html
Everything flows, but only the macromolecules are worth the time. Thursday, July 30, 2015. One of the more fascinating puzzles in contemporary polymer science is polydopamine. As you might guess, this is made from polymerizing dopamine, a fairly simple molecule:. Even though this monomer has been polymerized and extensively studied for 8 years, there still is disagreement on what the structure of the polymer is. And this has nothing. Look at this rogues gallery of structures that have been proposed:.

Everything flows, but only the macromolecules are worth the time. Wednesday, July 30, 2008. Getting Violent over Glass. The New York Times. Has a decent article on some of the latest research on the glassy state. It's more than the old does-glass-flow arguements and hints at some of the difficulties. About the nature of glass.". And 2) “Many people tell me this is very contentious. I disagree violently. With them.”. Emphasis added), I can tell the author got it right. Subscribe to: Post Comments (Atom).

It's the Rheo Thing: Where There's Smoke, There's Bad Smells
http://www.rheothing.com/2013/08/where-theres-smoke-theres-bad-smells.html
Everything flows, but only the macromolecules are worth the time. Tuesday, August 06, 2013. Where There's Smoke, There's Bad Smells. NineSigma has another pie-in-the-sky Request for Proposal (RFP): Eliminating the Smell and Smoke of Burned Hair. If you've ever been unfortunate enough to have smelled burning hair, you know how wretchedly bad it is. Why? All that sulfur shows up in a mixed bag of semi-oxidized molecules and the human nose is pretty sensitive to most sulfur compounds at low concentrations.

It's the Rheo Thing: I'm Going Back to School
http://www.rheothing.com/2015/08/im-going-back-to-school.html
Everything flows, but only the macromolecules are worth the time. Thursday, August 13, 2015. I'm Going Back to School. Summer is winding down here in the Northern Hemisphere and that means that it's back to school time. For the first time in 26 years I will be part of that. There will be the usual excitement of meeting new students/professors /staff, finding my way around a campus that I am unfamiliar with, new books and supplies and making sure I am in the right classroom at the right time. As you can i...

It's the Rheo Thing: Accelerated Aging, Flash Photography and Museums
http://www.rheothing.com/2012/07/accelerated-aging-flash-photography-and.html
Everything flows, but only the macromolecules are worth the time. Tuesday, July 31, 2012. Accelerated Aging, Flash Photography and Museums. I've written many times ( 1. Of the challenges of accelerated aging and how, when improperly performed, it leads to incorrect results. Last week [*] a new example came to "light" when it was announced that the standard policy in museums of banning flash photography is without factual basis. Martin Evans has some further thoughts to sum up the logic:. Martin Evans, Ph...

Everything flows, but only the macromolecules are worth the time. Wednesday, August 13, 2008. My only political comment and it's not political at all. Flat out, politics will not be a topic of discussion on this blog, but there is one blog that I want to mention for having an unusually rational look at the daily polling results and predicting the Electoral College Results. That decide the election, not nationwide polling. The site is FiveThirtyEight.com. Subscribe to: Post Comments (Atom). One of last we...
