Cases where Molecular Dynamics in Submicron Structures Held in Question by Quantum Mechanics Quantum mechanics negates Molecular Dynamics analysis

Quantum mechanics negates Molecular Dynamics analysis that assumes atoms in submicron structures have the same thermal heat capacity as in the Bulk.

Material Matters™ and Materials Matter™?_Part II_ Acknowledgement and Dedication to the late Prof. John Edwin Harris (Jack)

Dedication to a friend and mentor.

Jack Harris, the regular Materials World columnist, presents his views on topical issues under the heading Materials Matter. The journal has recently announced, "the sad news that Jack Harris, Fellow of the Institute (FIMM) died in February 2009. There will therefore be no Materials Matters columns for the time being. A full obituary for Jack will appear in due course in Materials World. "

Jack, Prof. John Edwin Harris, MBE, FRS, FREng, FIMMM to give him his full title, was a true friend, in that he gave me much needed encouragement to pursue my contribution to my profession as a metallurgist, materials scientist and engineer. He encouraged me, and certainly many others to write. His column and contact led me to write again in english, after many years in France. I was honored that he found time to exchange correspondence, giving a reference or again an opinion, often simply adding an (s) to make a word plural "for growth-inclusiveness versus exclusion" At the time he was Editor in chief of Interdisciplinary Science Reviews an Institute of Materials Minerals and Mining Journal. This was a timely reminder of the interdisciplinary nature of our subject it's art and practice. He introduced me to some of his friends, shining examples and role model to follow. This encouraged me to write regularly, not only my web pages but several full papers, and book reviews the latter on behalf of the Institute. His column, Materials Matter, in Materials World was the first page I turned to, upon receiving my members journal in the post each month.

-My last exchange with Jack was via the open comment through his column "Comparing nuclear power in France and England" and more specifically picking up his pointer on renewable energy Bureaucracy spawns chaotic energy policy', by Sir William Lithgow, The Times, 8 October 2008.
- Jack's last column corresponded with the 200th anniversary of the birth of Charles Darwin 150th anniversary of the publication of his epoch-making book, On the Origin of Species, published after his death.

For me Materials Matter™, in spite of Jack's passing away, will in my mind remain his trade mark, ™, a difficult act and to follow.

Jack's lead continues after his death. He once advised me in a quiet way that a good place to start an enquiry was via the Royal Society and her members. While writing this and thanks to the Internet, I paid a new visit to both Royal Societies of which Jack was a member, The Royal Academy of Engineering, FREng, and The Royal Society FR. My current interest being in media assisted learning, I was more than well recompensed both The Academy and The Royal Society propose rich media materials, Web TV, lectures and conferences which I viewed with Realplayer
The Royal Academy of Engineering Media Website TV and Video.
The Royal Society Media Website TV and Video.

Let me end with this quote from Lord Rees, (FRS) current president of the Royal Society, who described John Edwin Harris (Jack) as "a fine example of the 'activist' and socially concerned scientist. We need more like him."

A fuller tribute has been given by his friend Dr. Frank Duckworth and published in the Guardian.

PS. I hope you and more especially your family, your friends, colleagues and peers approve of my personal tribute and attempt to keep his memory and guidance alive for the benefit of younger generations, generations of scientists, engineers and writers. Jack was perhaps a gifted Alchemist.

Material Matters and Materials Matter™?_Part I_ Acknowledgements and Dedication

This is really a double appreciation and a dedication to a lost friend.

The first acknowledgment is to the Materials Chemists whom I feel I have been neglecting of late, although some overlap occurs with my Materials Science and Engineering "defined" site.

In this case I am referring, the reader to the commercial materials chemistry company Sigma-Aldrich and their Learning Centre freely available reviews Material Matters ™ (12 quarterly reviews from 2006 to date,subjects covered: Alternative Energy Materials,Biomaterials, Metal & Ceramic Science, Micro & Nanoelectronics, Nanomaterials, Nanotechnology,Organic Electronics, Polymer Science) and Tutorials.

Dedication to a friend and mentor.

Introducing Snap Shots from Snap.com - New Widget Enhanced Functionality

Introducing Snap Shots from Snap.com


I just installed a nice little tool on this site called Snap Shots that enhances links with visual previews of the destination site, interactive excerpts of Wikipedia articles, MySpace profiles, IMDb profiles and Amazon products, display in-line videos, RSS, MP3s, photos, stock charts and more.

Sometimes Snap Shots bring you the information you need, without your having to leave the site, while other times it lets you "look ahead," before deciding if you want to follow a link or not.

Please feel free to comment on this widget.

Should you decide this is not for you, just click the Options icon in the upper right corner of the Snap Shot and opt-out.

NEW RSS CHEM. BLOGS and WEBSITE FEEDS APPROACH - SCROLL DOWN

As a new year feature for 2009, I trust readers fellow bloggers and webmasters will appreciate my use of RSS feed.

Please do not hesitate to let me know how useful this approach is.

All sites are worth special mention some famous such as Chemistry World some less so bravely maintained by individual chemist.

Good luck and good chemisty for the common good.

NB. Check that you and your lab has a carbon foot-print bottom-up approach, for progress begins with science!

Whisky - Chemical up-date from the RCS-Chemistry World


Quote: "Donnez de l'eau à un Ecossais, il fera du 12 ans d'age!"

Translation.
"Give water to a Scot and he'll make a 12 year old mature malt whisky"

A materials chemist well worth knowing, especially at this time of year as the New Year 2009 approaches. Victoria "Gill" RCS, Editor at Chemistry World is well named for the article she wrote.

In "A Whisky Tour",
Victoria attempts to unlock some of the mysteries of Scotch malt whisky, and asks if whisky - Scotch to thze rest of the world, is the most chemically complicated drink in the world?

Put in a nut shell or should I say in a cask, whisky is a law in it's own right!

-The finely-tuned process of Scotch whisky production is governed by its own law -the Scotch Whisky Act
-There are 92 malt whisky distilleries in Scotland, and each one has a slightly different process with different stills, malts and casks for maturation
-Under the Act, Scotch whisky must be matured for at least three years, during which time the spirit reacts with compounds in the timber casks
-Chemists continue to study the complex effects of dilution on the sensory perception of whisky flavours.

Then some start their physical chemistry career studying bubbles in liquid steel publish in lessor known conference proceedings etc while others, more experienced, study bubbles in champagne, and publish via the ACS-American Chemical Society in no joking
