(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.

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]

WebSpectra - Problems in NMR and IR Spectroscopy

Chemistry online Resources

Link - http://www.chem.ucla.edu/~webspectra/


"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.

The Spectroscopy Net . Com


The Spectroscopy Net . Com

Chemistry online Resources

Link - http://www.thespectroscopynet.com/

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.

Spectral Database for Organic Compounds


Spectral Database for Organic Compounds

Chemistry online Resources


"Introduction to the Spectral Data Base (SDBS)

SDBS is an integrated spectral database system for organic compounds,which includes 6 different types of spectra under a directory of the compounds. The six spectra are as follows, an electron impact Mass spectrum (EI-MS), a Fourier transform infrared spectrum (FT-IR), a 1H nuclear magnetic resonance (NMR) spectrum, a 13C NMR spectrum, a laser Raman spectrum, and an electron spin resonance (ESR) spectrum.

Compounds: ca 33000 compounds
MS: ca 24000 spectra
1H NMR: ca 14700 spectra
13C NMR: ca 13000 spectra
FT-IR: ca 51100 spectra
Raman: ca 3500
ESR: ca 2500 "[1].
