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.

Physicists find ways to control gamma radiation

Researchers from Kazan Federal University, Texas A&M University and Institute of Applied Physics (Russian Academy of Sciences) found ways to direct high frequency gamma radiation by means of acoustics.

Shaking light with sound

Piezoelectric materials can convert electrical voltage to mechanical displacement and vice versa. They are ubiquitous in modern wireless communication networks such as in cellphones. Today, piezoelectric devices, including ...

Artificial bees from a pressure cooker?

What if we could create artificial bees that helped us with food production? Ola Gjønnes Grendal cooks up the materials needed to do just this.

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 ...
