“…5, a decrease in the Soret band at 445 nm was observed, with a concomitant slight increase in the typical Soret band at ∼417 nm. The disappearance of the peak (445 nm) suggested that oxidant active species (Mn IV O) were consumed by substrate [44][45][46][47]. In addition, during the reaction, the color changes in the reaction mixture also indicate the presence of such high-valence species.…”

Laminar nanocomposite of a-ZrP/MnTMPyP, [5, 10, 15, 20-tetrakis (N-methylpyridinium-4-yl) porphyrinato manganese (III)], was obtained through the selfassembly of a-ZrP nanosheets and manganese porphyrin molecules, namely the exfoliation/restacking route. The final products were characterized by several analytic techniques such as XRD, IR, UV-Vis, and SEM. Meanwhile, the surface charge change of layered zirconium phosphate during the restacking process was monitored by a Zetasizer Nano instrument. The zeta potential value of a-ZrP colloidal dispersion is -40.1 mV, indicating that the colloidal dispersion was stable and well dispersed. The cyclic voltammetry measurements of a-ZrP/MnTMPyP film-modified glass carbon electrode displayed a pair of well-defined oxidation/reduction peaks with redox potentials at -0.256 and -0.197 V with an increase in the peak current compared to MnTMPyP aqueous solution. Furthermore, a-ZrP/MnTMPyP hybrid thin film exhibited excellent electrocatalytic activities toward oxidation of nitrite. The oxidation peak current increased linearly with the square root of scan rate, suggesting that the electrocatalytic process was controlled by nitrite diffusion. Finally, a detection limit of 5.3 9 10 -5 M was estimated at a signal-to-noise ratio of 3.0 with a concentration range of 1.5 9 10 -4 to 4.76 9 10 -3 M.

Molecular mechanics calculations, based on equations such as the one below, are used to investigate a colorectal cancer drug, 5-fluorouracil, intercalated into a clay, montmorillonite. This combination is currently being considered as a drug delivery system. The swelling of clays has been studied since the 1930s and is still not fully understood. Spartan '14 is used for the calculations. Semi-empirical and ab initio basis set scaling is also examined since there are roughly 300 atoms involved in the full model.
