Flat polymer electrolytes promise thin-film power

Article Abstract:

New batteries made using a solid polymer electrolyte could radically change energy storage technology. The batteries will be thinner than a magazine page and will out-perform traditional liquid electrolyte batteries. The new batteries will operate at extremes of temperature and will not leak or discharge, unlike liquid cells. Tests have also shown that scaled-up versions of the batteries could provide five times the energy density of a lead-acid car battery. The new cells are both rugged and flexible, making them ideal for mechanical purposes. The first applications are likely to be as energy sources for smart credit cards, instant film packages and circuit boards on laptop computers.

PDPs show that thin is beautiful

Article Abstract:

Plasma display panels (PDPs) are expected to revolutionise home entertainment systems, offering great width-to-depth ratio which enables the screen to be wall-mounted. While PDPs have similarities with the cathode ray tube (CRT), the coloured phosphor cells in the former are controlled individually to enhance display. The technology is currently used in head-mounted virtual activity devices.

Colour me beautiful

Article Abstract:

Colour guidelines would provide a useful means of controlling colour application in built up areas of the country without imposing strict standards. Buildings, bridges, residential furniture and other structures are often painted green even though it can jar with surroundings and natural history. European countries have successfully adopted colour guidelines.
