CO2 is an important air pollution emission contributing to climate change. Researchers around the globe are looking at ways to remove CO2 from flue gasses and to store it (sequestering) or to in someway use it.
By tuning gold nanoparticles to just the right size, researchers from Brown University have developed a
Indian scientists have developed a filter system they say can provide clean water to rural families for less than $2.50 per year and help reduce incidences of diarrhea that cause tens of thousands of deaths in the developing world annually.

British researchers have discovered that sea urchins use nickel particles on their exoskeletons to effectively capture CO2 and turn it into a solid form, an intriguing finding that could offer an inexpensive way to capture and store carbon from fossil fuel-fired power plants.
In the search for more efficient solar cells, UCLA researchers have developed a new transparent solar cell that points towards the age when windows could become small solar energy farms without blocking the view. They have developed a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light (not visible light),
The standard solar cell uses silicon oxide, which is expensive and environmentally toxic. One of the promising alternatives is the so-called “Grätzel cell”, a cheaper, cleaner alternative based on more abundant titanium oxide. However, they don’t last long because this type of dye-sensitized cell uses an electrolyte made
Dutch scientists say they have developed a process that uses nanotechnology to convert plant matter into the basic components of plastics, an innovation that could ultimately provide an alternative to oil-based plastics in the manufacture of thousands of everyday products.
Renewable energy such as solar has a basic problem: No sun , no power. In order to make it more usable the Power must be stored for off peak use when the sun does not shine. Batteries though die when repeatedly recharged. Stanford researchers have developed part of better battery, a new electrode
