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.

Better understanding membranes

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.

Artificial spin ice toggles twist in x-ray beams on demand

New studies helped scientists understand how a nanoscale magnetic lattice (an artifical spin ice) acts as a toggle switch for x-ray beams with spiral character. The findings represent an important step toward the development of a versatile new tool for probing or controlling exotic phenomena in electronic and magnetic systems.
