Chemistry in our life. Here we try to show the continuous researches in chemistry. Self-healing coatings for steel. A conducting polymer film acts as a self healing coating to protecting metals from corrosion, say researchers in Japan. Damian Kowalski and coworkers at Hokkaido University have developed a new type of coating using an intrinsically conducting polymer (ICP), polypyrrole, which could be used as an alternative to expensive and toxic chromates currently used. The key to the system is the contr...

Chemistry in our life. Here we try to show the continuous researches in chemistry. Ferrofluids help you see better. US researchers have used ferrofluids as liquid pistons that could be used to make adjustable liquid lenses with nearly perfect spherical interfaces for applications such as an optometrist's phoropter. A phoropter measures the way light is focused in the eye and is used to determine prescriptions for glasses and contact lenses. Nicole Pamme, an expert in microfluidics from the University of ...

Chemistry in our life. Here we try to show the continuous researches in chemistry. Methane all lined up. Swiss researchers have found that the way methane molecules vibrate when they hit a nickel surface can have a huge effect on their reactivity. A molecule's reactivity is affected by its directional momentum and vibrational energy. 169; Bruce Yoder. When the researchers measured how much carbon was deposited at the metal surface after the methane and nickel had reacted, they found that methane molecule...

Scientists have deciphered the surprising structure of the perforin pore, which delivers the 'kiss of death' to virus-infected cells and cancer cells in the body. The perforin pore delivers the 'kiss of death' to virus-infected cells and cancer cells in the body. 169; Helen Saibil (Birkbeck College). The first major step in understanding perforin came from the discovery that it is related to...

Spanish scientists have established how natural products protect plants from sun damage. The compounds could be used as active ingredients in sunscreens. Using computational techniques on palythine - a compound found in coral - as a model compound, Diego Sampedro at the University of La Rioja, Logroño, investigated what happens to the molecule after it absorbs UV light. Mike Robb of Imp...

Chemistry in our life. Here we try to show the continuous researches in chemistry. Amino acid synthesis hints at how the genetic code expanded. The detailed pathway for the biosynthesis of pyrrolysine - the 22nd and latest amino acid to be discovered - has been outlined by US researchers. The results show that each pyrrolysine is made from two lysine precursors, pointing towards a route by which new amino acids could have been introduced into the genetic code during evolution.

The European Union says it will ban the controversial monomer bisphenol A (BPA) as a raw material in baby bottles due to concerns over its impact on human health. Companies in the EU will not be able to sell or import baby bottles made using BPA after 1 June 2011. No more BPA in baby bottles from 2011. The EU move has drawn criticism from the plastics industry, which says there is no...

Chemistry in our life. Here we try to show the continuous researches in chemistry. Carbon nanotubes in large panel displays. US researchers have incorporated carbon nanotubes into organic light-emitting transistors (OLETs) to create devices that rival the performance of their silicon counterparts. This technology could lead to much larger flat screen televisions and displays, which are also cheaper to manufacture. The team took the design one step further and incorporated an OLED layer into the carbon na...

Researchers in the US have used hydrogenation to introduce disorder into titanium dioxide nanocrystals, increasing the amount of solar light they absorb. They hope the black TiO2 produced could be used to generate cheap hydrogen fuel. Unmodified white and disorder-engineered black TiO2 nanocrystals. We have finally succeeded in making a TiO2 which is black in colour,' says Yu&#...
