Natural channel proteins are integrated into artificial membranes to facilitate the transport of ions and molecules. Researchers have now been able to measure the movement of these channel proteins for the first time.
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.
Researchers have shown that if you apply a strong magnetic field to the honeycomb lattice of carbon atoms in graphite, positive and negative charges form pairs, which may give rise to a superconducting-like state.
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.
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 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.
A method for making elastic high-capacity batteries from wood pulp was unveiled by researchers. Using nanocellulose broken down from tree fibres they produced an elastic, foam-like battery material that can withstand shock and stress.
