Generative model unveils secrets of material disorder

National University of Singapore (NUS) scientists have utilized generative machine learning models to explore the different methods in which atoms between adjacent crystals in a piezoelectric material, which are materials ...

Unique ferroelectric microstructure revealed for first time

A team of researchers have observed and reported for the first time the unique microstructure of a novel ferroelectric material, enabling the development of lead-free piezoelectric materials for electronics, sensors, and ...

Sound-induced electric fields control the tiniest particles

Engineers at Duke University have devised a system for manipulating particles approaching the miniscule 2.5 nanometer diameter of DNA using sound-induced electric fields. Dubbed "acoustoelectronic nanotweezers," the approach ...

A touch of gold sends crystals electric with excitement

A touch of gold—or another noble metal—can change the structure of a crystal and its intrinsic properties, physicists at the University of Warwick have demonstrated in a display of modern-day alchemy.

Some piezoelectric materials may be 'fakes'

Piezoresponse force microscopy (PFM) is the most widespread technique for characterising piezoelectric properties at the nanoscale, i.e., for determining the ability of some materials to generate electricity when subjected ...

Piezomagnetic material changes magnetic properties when stretched

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds ...

Researchers develop flexo-electric nanomaterial

Researchers at the University of Twente's MESA+ research institute, together with researchers from several other knowledge institutions, have developed a 'flexo-electric' nanomaterial. The material has built-in mechanical ...
