Packaging Materials Selector aids decision-making and change, just the infamous Plastic bag syndrome or a serious step in the proper direction?

I was awakened to the subject as a whole not just the plastic bag rubbish, which incidentally allowed me to freely recycle garbade to the incinerator, I trust rather than to landfil.(I was told the landfills are rolled hence there is no biodegradability worth the name. Now I pay for a similar product or use one which has no recycleability control

I'll just have to wait until the specialist members of The Institute of Materials Minerals and Mining, Clay, Packaging and now Wood provide some Co data. Hopefully members know of this site or of the well known Granta Eco-selector’s efforts.

Looking for a field to research, choose the people to follw: Royal Society 2010 Anniversary Professorships

N°1 for materials science and engineering or materials chemistry could be Andre Geim FRS, FinstP who is Langworthy Professor of Physics at the University of Manchester and is known primarily for the discovery of graphene. Graphene is a single layer of carbon atoms densely packed into a honeycomb lattice and the first representative of one atom thick materials which until 2004 had remained unknown. Graphene has many potential uses ranging from ultrafast transistors to bendable gadgets and from composite materials to novel batteries, and has been tipped as a likely successor to silicon in electronics. Geim is also known for his educational experiments on magnetic levitation (the "flying frog" experiment) and the development of a biomimetic adhesive known as "gecko tape".

2. The current hotest of topics is undoubtedly Climate Change. The professorship goes to Professor Andrew Watson FRS, University of East Anglia. He aims to improve our understanding of carbon sinks' and develop a model for the global accounting of the atmospheric CO2 budget. I intend to put more RS top quality studies on climate chage etc. in further wikis and on my blogs.

Materials Views: Materials Chemistry, Materials Physics, Materials Science Nano-science and technology

There is much to be leaned in all the fields underlined in the above post title.

The scope is wide and demandingly specialised in terms of the science, technologies and engineering involved, all brought together by Wiley Intercience in their very attractive publication, Materials Views. Moreover their currebt early views are freely available online to peruse or download accordingly.

Most papers deal with the nanoscale. I noted especially papers:
a) using the concepts of materials testing and strength,
b) energy vectors and storage, batteries, hydrogen storage..
c)electronic materials
d) biomimetics and softmaterials, polymers..

Run an eye over the list of papers and abstracts and make your own choices,
join me in reading your favourite subjects. And why not give your view your materials view?

Sincerely,
JA

Bioactive Glasses_J of Biomaterials Appications Sage Publications free until 31Oct09

A very rapid glance at the compositions of bioactive glases in this paper, may intregue process metallurgists and steelmakers all familiar with nature and composition of their favourite chemical reactant, slags. Could there be possibly routes to improving value in recycling this abondant by-product?

Feel free (till 31 Oct09) to read the journal.

Please do not hesitate to send all your feedback.

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.
