(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.

"CAS is a team of scientists, creating and delivering the most complete and effective digital information environment for scientific research and discovery. CAS provides pathways to published research in the world's journal and patent literature - virtually everything relevant to chemistry plus a wealth of information in the life sciences and a wide range of other scientific disciplines - back to the beginning of the late 19th century.

CAS, a division of the American Chemical Society, provides the world's largest and most current collection of chemical and related scientific information, including the most authoritative collection of disclosed chemical substance information, the CAS RegistrySM. CAS combines these databases with advanced search and analysis technologies to deliver the most complete, crosslinked, and effective digital information environment for scientific research and discovery, including such products as SciFinder, STN, STN Express, and STN AnaVistTM, among others"[1].

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]

NMR online workbook


NMR online workbook

Chemistry online Resources

Link - http://www.nd.edu/~smithgrp/structure/workbook.html

"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]

NMR at Widener University

NMR at Widener University

Chemistry online Resources

Link - http://science.widener.edu/svb/nmr/nmr.html

"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.

Chemistry online Resources

The Spectroscopy Net is an informal Web site for all aspects of Optical (Atomic) Emission Spectrometry. Those seeking other spectroscopies, in particular we have lots of requests for atomic absorption spectroscopy, might try to come back later again as we constantly work on this site to cover more aspects of Spectrometry. We have opend the The Spectroscopy Net for contributions by the Experienced Researchers and Early Stage Researchers of the Marie Curie RTN Gladnet to give them the possibility of informing the public about their research interests and to get training in writing scientific contributions dedicated to the general public. In particular the participants of the training courses organised by Gladnet are encouraged to write a small topic on the training lectures.

The Spectrocopy Net was designed by Dr Richard Payling to bring emission spectrometry to the web, to support practitioners, and to provide an informal exchange of information. Richard was Manager of Surface Analytical, Consultant to Horiba Jobin-Yvon France and Conjoint Associate Professor of Physics, The University of Newcastle, NSW 2380, Australia.

The world of Light, of Sun and Stars, of Atoms and Chemical Analysis. The Spectroscopy Net is an open, free resource for Spectroscopists everywhere and everyone interested in Atomic Spectroscopy.
