Nanoengineering boosts efficiency of materials that convert waste heat to electrical energy

By engineering a semiconducting material at the level of its individual atoms, Pierre Ferdinand P. Poudeu, assistant professor of material science and engineering, has boosted its ability to convert heat into power by 200 percent and its electrical conductivity by 43 percent. That's an important combination. Improving both of these figures at the same time is a major challenge for researchers working in the field.

Flexible opals (w/video)

A synthetic material which mimics the brightest and most vivid colours in nature, and changes colour when twisted or stretched, has been developed by researchers at the University of Cambridge, and could have important applications in the security, textile and sensing industries.

Paper could be basis for inexpensive diagnostic devices

Paper is known for its ability to absorb liquids, making it ideal for products such as paper towels. But by modifying the underlying network of cellulose fibers, etching off surface 'fluff' and applying a thin chemical coating, researchers have created a new type of paper that repels a wide variety of liquids - including water and oil.
