Preparing Single Enantiomers and Conformational Energy Freshman Organic Chemistry (CHEM 125) After mentioning some legal implications of chirality, the discussion of configuration concludes using esomeprazole as an example of three general methods for producing single enantiomers. Conformational isomerism is more subtle because isomers differ only by rotation about single bonds, which requires careful physico-chemical consideration of energies and their relation to equilibrium and rate constants. Conformations have their own notation and nomenclature. Curiously, the barrier to rotation about the CC bond of ethane was established by measuring its heat capacity. 00:00 - Chapter 1.

- Nikon D80 Digital SLR DISCOUNT Customer Reviews: "Since this camera just hit the streets less than 2 weeks ago, I obviously haven't had this for a super long time, but I moved to the D80 as an upgrade from the terrific D50, and the D80 takes care of every single minor nitpick I had with the D50, and then takes it even beyond that. Moreover, since I moved from the D50 and not a D70-series, I was thrilled that the D80 uses Secure Digital (SD) flash cards, which I used for not only my D50, but for my Casio EX-Z750 point and shoot as well. As with the D50, the D80 just feels terrific in my hand. I was concerned initially because the ergonomics of the grip have been ever so slightly modified (more like that of the D70s than the D50), and I really liked the feel of the D50. However, once I got the D80 and actually started using it and shooting with it, the concern evaporated quickly. The D80 is a complete success ergonomically... it feels solid and substantial without being excessively heavy. Nikon has really always excelled in this niche, which isn't something that shows up in most reviews or on any test charts. Moreover, the controls are very logically placed, easy to identify and use in real-world photography, and the menus are intuitive and highly functional. This camera is FAST. It's senseless to really even try to quantify it because the numbers (less than 0.1 second to start up) just don't convey how instantaneous shooting with this camera is. There's no discernible shutter lag ...

- Jumping at the Palindrome !! This level is the same forwards and backwards. It is a palindromic stereoisomer. From the middle to the end it is superimposable on the front half (a mirror image) and if translated 180 degrees from beginning to end remains the same. Originally this was what Level 47 really looks like without all the extra fluff (half way through, then mirror reflected), if you jumped it like an Advanced Challenge with thejump button held down continuously (see my running of Level 47 Advanced Challenge Intense Speed on YouTube). I had to change it slightly so it would be runnable backwards and forwards (following my original path would have left a 4 gap jump and up two on a sidewall... not doable) to make it a true Palindrome. There were 48 squares left over and i added a mini palindrome in the middle. Q: What kind of racecar does the president of the Palindrome Society drive? ........ A TOYOTA.

- Chemistry on the Web: How Can we Crowdsource Chemistry to Solve Important Problems? Google Tech Talk April 6, 2010 ABSTRACT Presented by Dr Matthew Todd, School of Chemistry, University of Sydney. Open Science: how can we crowdsource chemistry to solve important problems? Science shaped itself in the founding days of learned societies: individuals or teams competed, in secret, with paper-based communication in subscription journals. Why are we all still doing science like this? The internet has had a major impact in our sharing of data by traditional means, but it has not yet radically changed the way we actually perform science. My lab is involved in a new project a government/WHO-funded research project that is completely open, where we are trying to solve a serious problem in public health through basic research in organic chemistry. The project involves a wonder drug used to treat a tropical disease but we need to improve it, and fast: With an eye on the bigger issue, we propose open methods can allow science to happen faster than traditional means, but we do not yet have the tools to make this happen. This talk is about hard science and soft human nature. It is also an appeal for decent tools scientists need to collaborate properly. The over-riding requirement: low barrier to entry.

You are reviled, into lonely exile, Atone for your sins with a few hundred miles, But she still misses everything you do, Just another reason why I'm glad they exiled you.
