Pulsed-field gradient (PFG) diffusion experiments can be used to measure anomalous diffusion in many polymer or biological systems. However. it is still complicated to analyze PFG anomalous diffusion. particularly the finite gradient pulse width (FGPW) effect. https://www.diegojavierfares.com/amazing-price-Kicker-48CDF104-Comp-10-Down-Firing-Loaded-Subwoofer-Enclosure-special-find/
