A brighter design emerges for low-cost, 'greener' LED light bulbs

The phase-out of traditional incandescent bulbs in the U.S. and elsewhere, as well as a growing interest in energy efficiency, has given light-emitting diode lighting a sales boost. However, that trend could be short-lived as key materials known as rare earth elements become more expensive. Scientists have now designed new materials for making household light-emitting diode bulbs without using these ingredients.

'Superglue' for the atmosphere

It has been known for several years that sulfuric acid contributes to the formation of tiny aerosol particles, which play an important role in the formation of clouds. A new study shows that dimethylamine can tremendously enhance new particle formation. The formation of neutral nucleating clusters of sulfuric acid and dimethylamine was observed for the first time.

Designing future cities

New tools will merge urban design with scientific analysis to improve the decision-making process associated with large-scale urban developments. One such tool, called LakeSim, has been prototyped with an initial focus on consumer-driven energy and transportation demand.

Demolish, re-use, recycle and rebuild

Some 380 million tonnes of construction and demolition waste are generated every year and most of it ends up in landfills. Re-using and recycling components and materials is good for the environment and saves money, but industry has been less than enthusiastic. An EU-funded research project has laid the foundations for change - it is promoting concrete, ceramics, gypsum and plastics recycling around Europe.
