PARSIPPANY, N.J., Oct. 12 /PRNewswire/ -- Although the market for synthetic latex polymers in Europe is expected to grow at a modest CAGR of 0.9% through 2014, it continued to demonstrate a declining trend in 2009 due to significant contraction in major end-use markets. The total market was estimated at 2.5 million dry tonnes in 2009, according to latest report Synthetic Latex Polymers 2009-2010 Global Series: Business Analysis and Opportunities from worldwide consulting and research firm...

Researchers at Queen's University have discovered how molecules in glass or plastic are able to move when exposed to light from a laser. The findings could one day be used to facilitate medicinal drug distribution by allowing doctors to control the time and rate at which drugs are delivered into the body. The drugs, in a solid plastic carrier, could be released through the body when exposed to light. Lead researcher Jean-Michel Nunzi, a professor in the departments of Chemistry and Physics,...

Ultra-thin solar cells can absorb sunlight more efficiently than the thicker, more expensive-to-make silicon cells used today, because light behaves differently at scales around a nanometer (a billionth of a meter), say Stanford engineers. They calculate that by properly configuring the thicknesses of several thin layers of films, an organic polymer thin film could absorb as much as 10 times more energy from sunlight than was thought possible. In the smooth, white, bunny-suited clean-room...

A team led by a North Carolina State University researcher has shown that water-gel-based solar devices "artificial leaves" can act like solar cells to produce electricity. The findings prove the concept for making solar cells that more closely mimic nature. They also have the potential to be less expensive and more environmentally friendly than the current standard-bearer: silicon-based solar cells. The bendable devices are composed of water-based gel infused with light-sensitive...

The ability of phase-change materials to readily and swiftly transition between different phases has made them valuable as a low-power source of non-volatile or "flash" memory and data storage. Now an entire new class of phase-change materials has been discovered by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley that could be applied to phase change random access memory (PCM) technologies and possibly optical data...

The PhD thesis by Carlos Echeverría Arrondo, Doctor in Physics from the Public University of Navarre and entitled "On doped semiconductor quantum dots and magnetic nanowires", studied the behaviour and properties of nanometric-scale semiconductor crystals. The interest aroused by nanoscience and nanotechnology spurred Dr Echeverría to study the behaviour of semiconductor crystals when their size is reduced to less than one hundred nanometres (a nanometre is...

Tokyo, Sept 3, 2010 - (JCN Newswire) - Sony Chemical & Information Device Corporation commercialized and commenced full-scale mass production of the SP100 Series, Solar Cell Conductive Film for photovoltaic modules in April 2010. The SP100 Series is a film-type conductive bonding material that bonds the solar cell with the metal ribbon that acts as a transmission line for electricity generated by the cell and, compared with conventional soldering (200 C or more), is capable of...

Processes which lend materials new characteristics are generally complicated and therefore often rather difficult to reproduce. So surprise turns to astonishment when scientists report on new methods which not only produce outstanding results despite the fact that they use economically priced starting materials but also do not need expensive instrumentation. Just a simple framework made of polystyrene This is exactly what Jamil Elias and Laetitia Philippe of Empa's Mechanics of Materials and...

Collaboration by chemists, physicists and materials scientists at the University of Pennsylvania has created a simple and inexpensive method to rapidly grow centimeter-scale membranes of binary nanocrystal superlattices, or BNSLs, by crystallizing a mixture of nanocrystals on a liquid surface. The study demonstrates a new and spontaneous way to grow long-range-ordered BNSL membranes with rigorous control of nanocrystal size, shape and concentration by combining two types of nanocrystals and...

Old glass is not the same as new glass -- and the difference is not just due to manufacturing techniques. Unlike crystalline solids, glasses change as they age, increasing packing density and stability. Ideally, a glass should be cooled slowly, maybe over 10,000 years or so, but that is not usually practical. Research reported in the Journal of Chemical Physics, published by the American Institute of Physics (AIP), details the production of highly stable glass films of indomethacin by...


Word of the Day
cacodemon
  • An evil spirit; a devil.
  • A nightmare.
  • In astrology, the twelfth house of a scheme or figure of the heavens: so called from its signifying dreadful things, such as secret enemies, great losses, imprisonment, etc.
'Cacodemon' comes from a Greek term meaning 'evil genius.'
