(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.

"In both printed CA Issues and Indexes and computer-readable services, certain abbreviations and acronyms are automatically generated for terms in the abstract text, the keyword phrases, and the text modifying phrases for index entries. Most of these abbreviations have been used prior to 1982. Users of computer-readable services need to know these standard abbreviations and acronyms in order to be able to use them in search profiles and identify them in text.

In this document, automatically generated abbreviations and acronyms in CAS publications and services are arranged in three lists. To guide users to abbreviations they need to include in their search profiles, Listing A is arranged in the alphabetical order of the full terms which are abbreviated. Do not use periods when searching CAS abbreviations or acronyms online. To provide explanation of abbreviations encountered in text, Listing B is arranged in the alphabetical order of abbreviations and acronyms"[1].

Quantum States of Atoms and Molecules - Digital Book

Quantum States of Atoms and Molecules

Chemistry online Resources

Link - Read the Book,  its Free 

"Quantum States of Atoms and Molecules is an introduction to quantum mechanics as it relates to spectroscopy, the electronic structure of atoms and molecules, and molecular properties. A digital, living textbook, it provides opportunities not found in conventional textbooks—opportunities that allow students to develop skills in information processing, critical thinking or analytical reasoning, and problem solving that are so important for success.

In contrast to many quantum chemistry books, the relevant properties of atoms and molecules become part of the discussion immediately, and concepts are introduced at a concrete level and then generalized, and put in mathematical form at a later stage in the presentation. The goal is to establish the fundamental principles of quantum chemistry and their consequences in a rigorous way while not delaying the discussion of molecular properties until the end. This approach is based on the experience that a concrete verbal description paves the way for a more fundamental, mathematical approach.

The design goals of Quantum States are:

* Make the concepts and methodologies of quantum chemistry accessible and meaningful to all students.
* Develop an understanding of atomic and molecular properties in terms of quantum chemistry.
* Establish the fundamental principles of quantum chemistry and their consequences in a rigorous way while not delaying a discussion of molecular properties until the end.
* Encourage the development of information processing, critical-thinking, and problem-solving skills.
* Set the challenge for each assignment at a level that encourages the growth of critical-thinking and problem-solving skills, yet that can be achieved reasonably, though not always easily, by a student learning team facilitated by a master learner, the instructor.

Quantum States is suitable for a one-semester undergraduate or graduate course and can be part of a two-semester sequence in physical chemistry. It was developed with partial support from the National Science Foundation through grant NSF DUE #0127291.

A set of corresponding questions for student assessment is also available in the QBank collection of the JCE Digital Library"[1].

"This project began in the late 1980's as a means to supplement (or in some cases to largely replace ) the conventional textbook treatments of various topics in courses in General Chemistry and Environmental Chemistry. The purpose was in most cases to provide alternatives to what seemed to be the rather shallow standardized treatments of certain topics presented in many commercial textbooks. These became the "assigned reading" for several of my courses. Eventually, and with the help of an extensive set of computer-based lessons, I was able to eliminate the need for an "assigned" textbook for my General Chemistry courses. I did recommend that the students have access to a textbook of some kind, but it could be almost anything they could borrow or buy second-hand or remaindered"[1].

"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].
