Nano-spirals could guard against identity theft

Take gold spirals about the size of a dime and shrink them down about six million times. The result is the world's smallest continuous spirals: 'nano-spirals' with unique optical properties that would be almost impossible to counterfeit if they were added to identity cards, currency and other important objects.

Surface-modified nanoparticles endow coatings with combined properties

Depending on which property is desired, the nanoparticles used can be surface modified with organic moieties. Small Molecule Surface Modification (SMSM) bestows specific combinations of desired properties, for example hydrophilic, hydrophobic, adhesive, anti-adhesive, acidic, basic, inert or polymerizable.

Transient melting of a nanocrystal: seeing is believing

Scientists have discovered a spectacular transient melting phenomenon in nanocrystals. Coherent X-ray diffraction experiments have allowed snapshot imaging of a single 300 nm gold nanocrystal in the picosecond time interval after the particle was excited with a laser. The crystal was found to expand uniformly following the excitation and to reach the melting point about 50 ps later.

New composite protects from corrosion at high mechanical stress

Material researchers will be presenting a composite material which prevents metal corrosion in an environmentally friendly way, even under extreme conditions. It can be used wherever metals are exposed to severe weather conditions, aggressive gases, media containing salt, heavy wear or high pressures.

Researchers simulate behavior of 'active matter'

Researchers have shed new light on a particular class of active matter called active colloids - collections of tiny moving particles suspended in fluid. Using numerical models and computer simulations, the researchers show how spinning particles, pushed about by the fluid flows created as each particle spins, can arrange themselves into an array of emergent macro-scale patterns.
