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.

A miniscule water droplet is on the move, picking up speed as it glides along a stretch of thin, flat terrain. Abruptly, it hits a rough patch - the microscopic equivalent of glass speed bumps into which the droplet settles and stops dead.

Scientists have developed a new understanding of how electrons behave in strong magnetic fields. Their results explain measurements of electric currents in three-dimensional materials that signal a quantum Hall effect - a phenomenon thus far only associated with two-dimensional metals.

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.

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.
