2010 WILEY-VCH Verlag Gmb Photonic crystals (PhCs) are widely studied photonic structures that provide unprecedented control over the propagation of light. The large majority of PhCs are formed by a periodic modulation of the refractive index, i.e., a modulation of the real part of the dielectric constant. Additional functionality can be created by(More)
The effect of simultaneous ultrasonic and thermal treatment on kinetics and mechanism of nickel ferrite formation was studied. It was established that sonication leads to notable increase of the mean rate of this reaction and decrease of effective activation energy from 190+/-5 to 125+/-7 kJ/mol. XRD data show that ultrasonic treatment significantly affects(More)
