InnoCentive Challenges: Chemistry

You will find particularly motivating chemistry (physical-chemistry) related current problems to solve. The virtual office provides in-depth back-ground information on real-life materials chemistry and science based theoretical, technological and engineering problems to solve, many of which are cryingly urgent for many of the worlds populations. Complimentary information is provided upon solver request by InnoCentive's managing scientists who are in contact with both solution seekers (clients) and solvers (you and me).

Delays are short so check the link regularly, bookmark them and do not hesitate to contact me for any further assistance, co-operation, caring and sharing.

I have also included a rapid and permanently placed access link, RSS feed widget centred under the header block and also at the page foot, on my site-blog listings, centred block.

Biomodels to Biomimicry?

My title question is a stab in the dark and shows more about my material chemistry focus and my ignorance of serious biological background.

However I like to keep my eye on modelling activities, as an educational aid, otherwise biological process modelling is a thing I try to stay away from, highly specialised technical language and concepts.

That being said this data dase is certainly worth bookmarking for either of the above categories for current or future use and hopefully may generate a few tips from the pros on how to make a few more steps in biomimicry?

The teraton challenge. A review of fixation and transformation of carbon dioxide, Danish work brought to us by RCS-The Royal Chemical Soc.,UK.

A few months ago a Prof. of Chemistry friend at a major Univ. in France expressed scepticism concerning the CCS - carbon capture and sequestration, the geological and geoengineering response to increases in CO2 a well documented GWG-global warming gas. (Increases roughly since James Watts invention of the steam engine Cf. David JC Mackay's book "Without Hot Air" "David JC Mackay's book "Without Hot Air") my chemist friend's objection concerned dangers of stored carbon escape since CO2 is not in a chemically combined and imprisoned form. Of course the physicists, and geological engineers consider that suitably stable, deep sites may be found whereby high pressures in deep wells is sufficient to maintain the CO2 in the liquid, or pseudo liquid (super-saturated) state to remain simple. More audacious consider that by avoiding sequestration in valleys especially inhabited valley even if there is gas escape there will be no serious consequences.

Whatever, I am extremely pleased to find this Danish work via my blog listed RSS feed whereby CO2 mitigation is suggested by physical-chemistry methods which should come closer to meeting the approval of my chemistry friend.

The Danish consider what they feel are six important CO2 transformations namely:
1. chemical transformations,
2. photochemical reductions,
3. chemical and electrochemical reductions,
4. biological conversions,
5. reforming and inorganic transformations.



In addition, the vast research area of carbon capture and storage is reviewed briefly.

Such reviews should help suggest and channel themes of research and thus improve the overall mastering of our incredible capacity to generate CO2 in energy production,industry and transportation.

The electronic properties of graphene and carbon nanotubes from Nature asia pacific

A brief review is given on the characteristic features of electronic states and transport in graphene consisting of a single sheet of graphite, and its cylinder form called a carbon nanotube by Tsuneya Ando a renowned Japanse expert in these fields.

This is a timely and highly readable review as one would expect from Nature and Associates.

This full review and more about the author as well as many other papers and reviews may be found in the new NPG Asia Mater Journal on simple registration.

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
