Researchers at Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) have developed an innovative microscopy ...

Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

Relaxor–ferroelectric materials are high-performance ultrasound generation elements exhibiting large dielectric responses owing to their complex structures. Recently, researchers from Japan made use ...

PFM is based on the converse piezoelectric effect, where an applied electric field induces mechanical strain in piezoelectric materials. In PFM, an AC voltage is applied between a conductive atomic ...
