Optical Elastography: From Theory to Clinical Applications

Magnetoelectric Response in Multiferroic SrFe12O19 Ceramics

We report here realization of ferroelectricity, ferromagnetism and magnetocapacitance effect in singleSrFe12O19ceramic at room temperature. The ceramics demonstrate a saturated polarization hysteresis loop, two nonlinear I-V peaks and large anomaly of dielectric constant near Curie temperature, which confirm the intrinsic ferroelectricity of SrFe12O19 ceramicswith subsequent heat-treatment in O...

Optical activity from racemates.

To the Editor — The relationship between chirality and optical activity is an important consideration for various fields of chemical, physical and biological research. For example, the determination of optical activity is a routine test of enantiomeric purity in organic synthesis. Chiral materials (or other non-centrosymmetric (NCS) materials) are also commonly used in optics and photonics to c...
