Looking to make solar panels cheaper, MIT researchers have created sheets of glass coated with advanced organic dyes that more efficiently concentrate sunlight. The researchers, whose results appear in this week's issue of Science, say that the coated glass sheets could eventually make solar power as cheap as electricity from fossil fuels.

Harnessing the energy of the sunlight that you purposefully block from your eyes while out on a bright and cheery day. Sounds very waste not, want not, right? Well, a group of designers came up with just the solution you may want for this notion, and it just might be the best looking solar powered accessory we've seen so far. The glasses are called SIG, or "Self-Energy Converting Sunglasses" and they can power your iPod or PSP while you're out walking around. The lenses are made of dye solar cells, and your iPod can plug into the jack at the bottom of the frame.

The main component of CT/X-ray Contrast Media is iodine. The Iodinated Contrast Media is a colorless, transparent, slightly viscous liquid. At present, the CT contrast agents can be mainly divided into ionic and non-ionic, according to the osmotic pressure can be divided into hypertonic, isotonic and hypotonic. Currently, non-ionic, isotonic or hypotonic Contrast Media are used clinically. When the CT contrast medium is injected, 97% of the contrast media products can be directly excreted from the kidneys within 1 day.

Industry wastewater treatment is a complex process since there are different kinds of pollutants against different industries, such as petrochemical industry, Coal Chemical Industry,Dye chemical, pesticides industry, Pharmaceuticals, electroplate industry, Electronic industry, hydrometallurgy industry.
