ChemIONS

this equation is chemically balenced, but is incorrect some other way. State what is wrong with the equation and rewrite it correctly

 NH3=N+3H

i think my teacher made a mistake but still....I need answers

A new measurement technique which mingles the amazing resolution of atomic force microscopy and the exceptional chemical identification of infrared spectroscopy is been developed by researchers from University of Illinois! Researchers demonstrated that imaging extraction and chemical analysis of femto-gram samples can be achieved using a heated cantilever probe in an atomic force microscope. They used a silicon cantilever probe with an integrated heater-thermometer.

The cantilever tip temperature can be precisely controlled over a temperature range of 25 to 1,000 degrees Celsius. Using this special cantilever probe, anyone selectively image and extract a very small sample of the material to be analyzed. Also the actual mass of this sample can be determined by a cantilever resonance technique. For the analysis the sample, the heater temperature is raised to slightly above the melting point of the sample material. The material is then analyzed by complementary Raman or Fourier transform infrared spectroscopic imaging, which provides a molecular characterization

Few days back, Biofuels was in top headlines of British newspapers as a team of scientific experts suggested the government to review their Biofuel Policy.  This invites some thoughts on Biofuels- are they a real promise or a disappointing alternative?

The increasing oil prices and their less availability together with the alerts on global warming triggered the recent increased interest in Biofuels.  Different countries, depending on their flora and fauna, explore the possibilities for Biofuel production, like corn and soybeans in US, cane sugar in Brazil, palm oil in Indonesia etc.  The sugar crops are fermented with microbes and enzymes on industrial scale to produce Bioethanol, while oils from crops are heated and changed their characteristics to produce Biodiesel.

Hope u all wont try to shut my mouth!

We already heard a lot of these types of stories. What I wonder is that, why these type of chemistry related extra solar discoveries are short lived. Recently flashed news reads that (and in Nature 2008 also!), scientists scrutinizing the Hubble’s telescope data have found the presence of Methane in an extra solar planet named HD 189733b. The Planet is orbiting its sun some 65 lightyears away and recorded an atmospheric temperature of 1000K. This however  ruled out the existence of methane emitting living organisms in HD 189733b.

If scientists say that the signature of methane is surprising in these types of distant planets, as they expected the planet's atmospheric carbon to be largely in the form of carbon monoxide, then why doesn’t it surprises the fellow researchers in ch

Hi friends, I read the intereting blog from heinzmartin, and thought of inviting your attention to another recent bio-inspired research by some motivated chemists..

Have you ever thought of cell phones with virus-based rechargeable batteries?  What do u feel of cell phones which mend their cracks when dropped?   Interesting, isn’t it?    Well, this was the real motivation for Prof.  Angela Belcher and her colleagues from MIT, who developed the first biologically based nano-scale rechargeable battery. 

Belcher is the director of Biomolecular Materials Group at MIT, and her research won MacArthur Fou

Eventhough im a keen observer of changing trends in chemical industry and research this new research idea came to me only recently. What I feel is this has more potential than superconductivity (allan rov's blog) as far as Chemists are concerned. there has been a lot of discussions going on in Bio-inspired chemistry and RSC arranged some meetings and conferences last year(?).

Maintaing a healthy and clean environment and tackling the increasing fuel and oil prices and decreasing fossil fuel supplies are beeing big manace for scientists. I think we chemists can effectively address these current problems by giving importance to bio-inspired chemistry. There is notion that only solar cells and wind energy is available for tackling these problems. Very few are looking towards Chemistry for alternative energy sources. (ofcourse some university researchers).

Chemists, by understanding the basic processes of some biological models can  create systems that mimic biomolecules and produce energy in an efficient and cost effective manner. This simple idea is nowdays term

 Hope you already heard this news. An interesting new research topic in chemistry?

 Researcher Dr. John Tse and his colleauges in Germany reported superconducting activity in a new family of
hydrogen compund. They put hydrogen in to a molecular compund and applied high pressure inorder to get superconductivity.
Most commercially available superconducting materials operates only at very low temperatures. This requires
super cooling equipments which are highly expensive.Their research in this area is aimed at improving the
critical temperature (Tc) for superconductivity so that new superconductors can be operated at higher temperatures
or even without a refrigerant. Anyway this seems to be an important breakthrough in modern Chemistry. Superconductivity
almost lost its past charm and glamour in research and now this brilliant chemists opened a new way
in modern chemistry.

Well..This seems to me a much interesting community to share my thoughts. Being an organic chemistry student i feel i can start a blog on the topics that suits aspiring chemists seeking a research position in UK or in entire EU. I have been in this freternity for some reasonably long time of more than 5 years. Its better to share my experience now.....

Are U a fresh chemistry graduate? Thinking of joining for a PhD? then here are some tips which i can recollect based on my past experiences.

For those who wish to join for a PhD, my first advice is that be sure you are ENOUGH Motivated. Its a long term 'struggle' spaning your mid twenties or even more! Eventhough the grants and fellowships are fair enough to make an income for a PhD student (in EU), its hard to be in the turbulent stream of Research for more than 4 years. But this doesnt matter if you are enough motivated. After all the final 'Fruit' is yours! getting a prefix 'Dr' and building an excellent career there onwards is really exciting and much more eazy nowadays.

Finding an area of interest is your next

Being a synthetic chemist, one always go through a variety of experiences, sometimes thrilling, some other times exciting, but highly disappointing most of the times! To be an enthusiastic chemist, it demands a high content of positive energy from inside and a bright ray of hope or inspiration.  Often those reactions which are feasible by all means turns up to be futile, wasting a lot of money and a lot more precious time. 

Why does it happen? Some people say it depends on the physical conditions, some others say it depends on the chemists' skill. But is it true? Even if a skilled person could make it happen, will he able to repeat it consistently? Giving attention to details and a very keen observation of condiions, like the amount of solvent, whether solid phase or solution phase reaction is more favoured etc. may help a sharp minded chemist to excel in his/her synthetic persuites. 

The thing is that there are a lot of synthetic reactions which are very much feasible and there are a variety of chemical products availabel on the market (with some of them with killing p
