NRL Develops Polymer Nanofibers for Chemical and Biological Decontamination →
Chemical and biological threats pose a significant concern not only to the modern warfighter but an ever-increasing number of individuals and groups. This threat is compounded by the persistence of these agents and the possibilities of causing increased personnel exposure by the relocation of contaminated materials.

MIT discovers a new state of matter, a new kind of magnetism →
Researchers at MIT have discovered a new state of matter with a new kind of magnetism. This new state, called a quantum spin liquid (QSL), could lead to significant advances in data storage. QSLs also exhibit a quantum phenomenon called long-range entanglement, which could lead to new types of communications systems, and more.

Lava dots: Hollow, soft-shelled quantum dots created →
Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new “lava dot” particles were discovered accidentally when researchers stumbled upon a way of using molten droplets of metal salt to make hollow, coated versions of a nanotech staple called quantum dots.

Scientists build ‘smart’ material made of DNA →
UC Santa Barbara scientists Omar Saleh and Deborah Fygenson have created a dynamic gel made of DNA that mechanically responds to stimuli in much the same way that cells do.

Can cobalt nanoparticles replace platinum? →
Platinum works well as a catalyst in hydrogen fuel cells, but it has at least two drawbacks: It is expensive, and it degrades over time. Brown chemists have engineered a cheaper and more durable catalyst using graphene, cobalt, and cobalt-oxide — the best nonplatinum catalyst yet. Their report appears in the journal Angewandte Chemie International Edition.

For About $20, Cardboard Bicycle Could 'Change The World,' →
An Israeli inventor has come up with a way to make a bicycle almost entirely out of cardboard — and so inexpensively that he thinks retailers would only need to charge about $20 for one.

Tanks' Special Paint Protects Against Nerve Gas →
Heavily armored tanks can’t protect the soldiers inside from chemical weapon attacks without some outside help. The British military has teamed up with a paint manufacturer to make a special coating for its Warrior tanks capable of absorbing nerve gas.

Quantum Dots Give Notebooks a New Glow →
A layer of nanomaterial that gives a liquid-crystal display the rich range of colors usually possible only with more expensive technologies will be commercialized later this year by the materials giant 3M and Nanosys, a private company in Palo Alto, California. Nanosys representatives say they are in talks with major display manufacturers to adopt the quantum-dot films, and that they will be in a 15.6-inch notebook computer available next year.
