Illuminating plastics
Article Abstract:
Light-emitting polymers (LEP) are used in flat, high-definition (HD) display panels because of their electroluminescence that produce higher quality display, wider viewing angle and without blurring of fast-moving pictures. The Cambridge Display Technology, in collaboration with the electronics company Seiko Epson, utilized its LEP expertise in developing a small, HD monochrome plastic television screen. The screen possessed two layers of metals acting as electrodes with a later of LEP in between them.

Forcing the issue
Article Abstract:
Composite metal-ceramic castings have advantages in application such as engine cylinder blocks and brake discs, but they have high production costs because of the high pressure squeeze casting process. However, the addition of a small amount of bismuth to the alloy wet the fibres more effectively and produced a stronger composite. Lower pressure techniques involve blowing the metal at around 100psi through the preform, keeping the oxide thin and allowing wetting to take place.
