(1) MIT: New insights on fusion power

David Chandler, MIT News Office
December 3, 2008

Research carried out at MIT's Alcator C-Mod fusion reactor may have brought the promise of fusion as a future power source a bit closer to reality, though scientists caution that a practical fusion powerplant is still decades away.

(2)Disappearing superconductivity reappears -- in 2-D

Scientists studying a material that appeared to lose its ability to carry current with no resistance say new measurements reveal that the material is indeed a superconductor -- but only in two dimensions. Equally surprising, this new form of 2-D superconductivity emerges at a higher temperature than ordinary 3-D superconductivity in other compositions of the same material.

FTNMR Free Induction Decay Archive

FTNMR Free Induction Decay Archive

Chemistry online Resources

Link - http://rainier.chem.plu.edu/fid_archive.html

"In this archive you will find 1H and 13C NMR free induction decay (FID) files of small organic molecules. The FID's in this archive were acquired on the 300 MHz broad band FTNMR spectrometer at Pacific Lutheran University and are available in the formats described below. This data is provided free as a service to the educational community. If you download and use this data we ask that you acknowledge the Pacific Lutheran University FTNMR FID Archive. Thank you.

A special section of this archive is dedicated to the NMR spectra used in Solomons and Fryhle Organic Chemistry, 7th Edition (John Wiley & Sons, Inc., New York, ©2000). The Solomons and Fryhle section of the archive is provided in cooperation with John Wiley & and Sons, Inc.

Free induction decay files may be downloaded for processing and viewing in either NUTS ( Acorn NMR) or Felix for Windows (Molecular Simulations, Inc.) format. Either program can be configured as a viewer in your WWW browser.

Another feature of the PLU FID Archive is a searchable database of 94 processed 1H spectra in NUTS format, complete with structure image files. This feature has been provided by Acorn NMR and is available from the PLU chemistry ftp site (ftp.chem.plu.edu). The spectra and image files are compressed in a single 9.2 megabyte .zip file. Instructions for downloading and handling the .zip file are here. "[1]

"This online workbook has been developed for senior undergraduate and graduate students learning to solve the structures of organic compounds from spectroscopic data. Most problems contain an IR spectrum (film or KBr pellet), a 500 MHz 1H NMR spectrum, a 125 MHz 13C NMR spectrum, and a 70 eV electron ionization Mass Spectrum. In the 1H NMR spectra, the phrase "exchanges" means that shaking the NMR solution with D2O resulted in loss of the signal due to H/D exchange."[1]

"This site includes

  • An outline of the talk.
  • Descriptions of some Freely distribueted software programs I have found useful for teaching.
  • Descriptions of the commercial NMR software I have tried out.
  • Mathcad documents that I have developed for teaching NMR concepts.
  • NMR Data from Advanced Spectroscopy at Widener Unviersity that highlights several NMR concepts.
  • Links to NMR sites on the Internet.
  • Details of the NMR Concepts Listserv.

Use of some of the information on theis web site requires the use of helper applicaitons. These are already installed in the student laboratories at Widener. Others will have to install these helper applications to make full use of this site. More information about helper applications used here."[1]

"This site was established to provide chemistry students with a library of spectroscopy problems. Interpretation of spectra is a technique that requires practice - this site provides 1H NMR and 13C NMR, DEPT, COSY and IR spectra of various compounds for students to interpret. Hopefully, these problems will provide a useful resource to better understand spectroscopy.
