How to Trap a Rainbow

Groovy! A team of electrical engineers and chemists at Lehigh University have experimentally verified the “rainbow” trapping effect, demonstrating that plasmonic structures can slow down light waves over a broad range of wavelengths. The idea that a rainbow of broadband … Continue reading

Help from Kelp

Researchers at Rice University have used inexpensive size-tunable microsponges derived from seaweed to store biomarkers in a device the size of a credit card which can be magnified and viewed by a microscope assembly the size of a toaster. That … Continue reading

Twelve Tensegrity Structures

From Oobject: Buckminster Fuller coined the term tensegrity when he saw sculptures by Kenneth Snelson and realized that rigid component geodesics were a special case of perfectly balanced compression and tension. Tensegrity refers to structures where compression members (rods) are … Continue reading

Beyond Graphene: More Kinds of Nano-sheets

Graphene, a sheet of graphite one atom thick, is no longer the only planar nano-material. A novel way of splitting materials into sheets just one atom thick could lead to new electronic and energy storage technologies, scientists said Thursday. … … Continue reading

A Glass Both Strong and Tough

From Scientific American: A metal alloy masquerading as a glass is the first material to be fabricated that is as strong and as tough as the toughest steel. The feat could eventually see such materials replace steel in buildings, cars … Continue reading
