(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].

"Polysaccharides are biologically produced (bio-based) materials that have a unique combination of functional properties and environmentally friendly features. Polysaccharides are also polymers and their long chain structures, as in man-made polymers, provide good mechanical properties for applications such as fibers, films, adhesives, melt processable plastics, thickeners, rheology modifiers, hydrogels, drug delivery agents, emulsifiers, etc. They are renewable materials, produced from other biological compounds, and generally are non-toxic and biodegradable. These features make polysaccharide materials a natural fit for sustainable development. Commercially available products include starch, cellulose and its derivatives (such as cellulose acetate, carboxymethyl cellulose, and methyl cellulose), sodium alginate, xanthan gum, dextran, carrageenan, and hyaluronic acid. Research continues to bring us new materials with improved performance and lower costs. This website is dedicated to promoting the commercial development of polysaccharide materials.

"About the Directory ABC Chemistry : Free Full-Text Journals in Chemistry

Accessibility of a great number of online chemistry journals is subjected to a mixed paying policy: the publisher may grant free access to a selected set of volumes (issues) while the admission to the rest of the database may be open just to subscribers or paying visitors. Quite often the information on the availability status is hidden deeply in the publisher's website pages and this complicates finding the free part of content.

The Directory makes this task easier by listing the fully and partly free journals that comply with the following criteria:

* publisher's grading of a journal as peer-reviewed;
* one-year, at least, free full-text content, or extensive free supplements to printed versions of papers;
* chemistry or chemistry-related subject coverage;
* English language of articles (journals in Russian are also listed on a separate page).

We selected the journals based on their free availability to reader, but not on publishers’ strategies, which were different (Open Access Initiative, publisher's promotional strategy, government's funding, etc.) for different journals and publishers"[1].

Chemistry online Resources

"The CCP1GUI project has arisen as a result of demand within the UK academic community (principally through CCP1) for a free, extensible Graphical User Interface (GUI) for community codes, particularly for teaching purposes. There is also a long-standing requirement for a graphical interface for the GAMESS-UK quantum chemistry programme, which we plan to satisfy using the CCP1 developments.

The GUI has been built around the Python open-source programming language and the VTK visualisation toolkit, both of which have been ported to all the major operating system platforms. The GUI is therefore capable of running on all of these systems. Distributions of the GUI have already been successfully tested on Windows, and Suse and Redhat Linux distributions, and packages for these distributions are freely available from our ftp site.

The CCP1GUI has been released under the GNU GPL licence and is freely available to download. Downloads are available from the CCP1GUI pages on sourceforge or from the ftp site of the Computational Chemistry Group at STFC Daresbury Laboratory.

The design of the GUI makes the most of Python's high degree of object-orientation, including advanced features such as multiple inheritance. The strong reliance on object orientation means that it is quick and easy to create interfaces to new computational chemistry codes as the need arises. The GUI already has a highly-featured interface for the GAMESS-UK program, and there are working interfaces for Dalton, Molpro, ChemShell and MOPAC"[1].
