Polymer Incorporated into Multi-Walled Carbon Nanotubes Increases Light Emission

Organic based solution processable devices are promising to revolutionise the lighting and photovoltaic industries of the future. The move away from traditional inorganic materials is driven not only by cost considerations, but also sustainability issues and life-cycle costs. However, current organic device efficiencies and lifetimes are not high enough for many applications.

Nanoscale Titanium Dioxide Particles Help Protect Plastics from Sun Damage

DuPont today introduced DuPont(TM) Light Stabilizer 210, a product designed as sun protection for plastics. The product uses extremely small particles of titanium dioxide to efficiently absorb ultraviolet light, protecting plastic and anything it covers from the sun's damaging rays. Because a sizeable percentage of titanium dioxide particles in the product are nanoscale, it was selected as a demonstration case for application of the Nano Risk Framework that DuPont and Environmental Defense introduced in June. The Framework is a systematic and disciplined process to evaluate and address the potential risks of nanoscale materials.
