Peptide nanoparticles marked for in vitro visualization

Using covalent self-assembly, researchers managed to synthesize new functional supramolecular systems based on dipeptides and genipin (a cross-sewing agent derived from plant material). The particles are polymer spheres 200-300 nanometers in diameter.

Mechanically imprinting atoms in ceramic

Researchers have, for the first time, succeeded in inserting a dislocation into a ferroelectric ceramic by mechanically imprinting the atoms in the material, a procedure that hitherto has only ever been used in metals.

Reaping the benefits of noise

Signals can be amplified by an optimum amount of noise, but this so-called stochastic resonance is a fragile phenomenon. Experimental research shows that stochastic resonance becomes robust to variations in the signal frequency when systems have memory. This has implications in many fields of physics and energy technology.

It takes some heat to form ice on graphene

Scientists detail the complex physical processes at work to understand the chemistry of ice formation. The molecular-level perspective of this process may help in predicting the formation and melting of ice, from individual crystals to glaciers and ice sheets.

Shiny mega-crystals that build themselves

Researchers are playing with shape-engineered nanoscale building blocks that are up to 100-times larger than atoms and ions. And although these nano 'Lego bricks' interact with each other with forces vastly different and much weaker than those holding atoms and ions together, they form crystals all by themselves, the structures of which resemble the ones of natural minerals.
