Cellular uptake results in RAW 264.7 macrophage, Caco-2, and LS174T cells confirming the efficient cellular uptake of nanoparticles in all three cell lines. More importantly, the bidirectional transport (absorptive and secretory) of MER across Caco-2 monolayer was significantly improved for both MSN-based formulations, particularly MSNs coated with a polymer (Eud-MER-MCM-NH2) where permeability was significantly enhanced (∼2.4-fold) for absorptive transport and significantly reduced (∼1.8-fold) for secretory transport. Finally, in vitro antibacterial activity [minimum inhibitory concentration (MIC)] and time-kill assay against S. aureus and P. aeruginosa showed that drug-loaded nanoparticles were able to retain antibacterial activity comparable to that of free MER in a solution at equivalent dose. Thus, Eudragit-coated silica nanoparticles could offer a promising and novel solution for oral delivery of Meropenem and other such drugs.We present an enhanced catalytic efficiency of palladium (Pd) nanoparticles (NPs) for the electrocatalytic hydrodechlorination (EHDC) reaction by incorporating the tetraethylammonium chloride (TEAC) ligand into the surface of NPs. Both experimental and theoretical analyses reveal that the surface-adsorbed TEAC is converted to molecular amine (primarily triethylamine) under reductive potentials, forming a strong ligand-Pd interaction that is beneficial to the EHDC kinetics. Using the EHDC of 2,4-dichlorophenol (2,4-DCP), a dominant persistent pollutant identified by the U.S. Environmental Protection Agency, as an example, the Pd/amine composite delivers a mass activity of 2.32 min-1 gPd-1 and a specific activity of 0.16 min-1 cm-2 at -0.75 V versus Ag/AgCl, outperforming Pd and most of the previously reported catalysts. The mechanistic study reveals that the amine ligand offers three functions the H+-pumpin
