Drug-Releasing Tannic Acid-Mediated Adhesive PEG Hydrogel for Porous Titanium Implants

“…0.5 < n < 1 indicates an anomalous transport process, which corresponds to Case III and the structural relaxation. n = 1 indicates a non-Fickian or Case II mode of transport. − As expected, the fitted n , shown in Table S1, indicates that the amount of TA affects the release mechanism, and two mechanisms are identified. The values of n for H-TA20, H-TA30, H-TA40, H-TA60, and H-TA80 are 0.51 ± 0.01, 0.22 ± 0.01, 0.22 ± 0.01, 0.24 ± 0.02, and 0.23 ± 0.01, respectively, indicating that only H-TA20 demonstrated Fickian diffusion, while the other hydrogels performed pseudo-Fickian diffusion.…”

Application of (Electrochemical) Impedance Spectroscopy to Investigate the Degradation of Epoxy Mold Compounds for Plastic Encapsulation of Power Electronics—A Feasibility Study

“…Nevertheless, “non‐Fickian” diffusion is evidenced in the present case. So‐called “non‐Fickian” diffusion is recently discussed in the literature but is usually associated with decreasing diffusion rates over time until reaching the saturation state due to nonstationary diffusion coefficients [38–40]. In the present case here, an increasing rate of water uptake has been observed.…”
