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.

A new class of membranes promises highly interesting applications in material separation, whether in biotechnology or water purification. The theoretical understanding of these polymer membranes is, however, still incomplete. Researchers now present a study that identifies these gaps in knowledge and shows promising approaches toward solving them.
