We report a sono-Fenton strategy to mediate the supramolecular assembly of metal–phenolic networks (MPNs) as substrate-independent coatings using phenol and phenyl derivatives building blocks. The process is initiated from generation hydroxyl radicals (.OH) high-frequency ultrasound (412 kHz), while metal ions synergistically participate in production additional .OH for hydroxylation/phenolatio...

Ion channels are naturally occurring pores through the proteins that regulate the passage of ions and thus maintain the concentration of ions inside and outside the cell. The ion channels control many physiological functions and they can show selectivity for a specific ion. Ion channels are mostly observed in nerve cells and muscle cells. The influx of ions into cells can be regulated by a gate...

the ion-pair association constant values, related to the reaction +  were determined by means of the nmr spectroscopy. the values of the thermodynamic functions of the ion pairing process were calculated on the basis of the nmr results. in addition, the association entropy was found to be dependent on the temperature. comparing the experimental data and the fuoss theory it is found that  ion-pa...

Anthranilate synthase in Pseudomonas putida is a two component enzyme system. The proteins, termed AS I and AS II, have respective molecular weights of 65,000 and 18,000. Five additional Pseudomonas species, both tryptophan requiring and independent strains, were examined and all were shown to contain similar two component systems. Anthranilate formation by "amide transfer," with L-glutamine as...
