Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect-free materials break? Until recently, the question was purely theoretical; making a defect-free material was impossible. Now that nanotechnological advances have made such materials a reality, however, researchers have shown how these defects first form on the road to failure.

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.

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.

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.
