Extraction of bioactive compounds from New Zealand Manuka leaves (Leptospermum scoparium) using emerging technologies
… The maximum improvement was achieved when pulses frequency (Hz), time, and extraction temperature of 788 Hz, 59 min, and 60 ℃, respectively. Results were found to be 1.58 times higher than thermal extraction. The electric field intensity was limited to 2.27 kV/cm due to cell design limitation and …

Characterization of Pharmaceutical Materials by Thermal and Analytical Methods
… in the solid state at frequencies of 0.1 - 1.00 Hz and to greater than 30 ¿¿C below the melting transition as the peak melting temperature. This describes the “activation energy method”. An Arrhenius plot, log ionic conductivity vs. reciprocal temperature (1/K), of the pre-melt DEA transition …
