Intrinsic enzymatic properties modulate the self-propulsion of micromotors

Bio-catalytic micro- and nanomotors self-propel by the enzymatic conversion of substrates into products. Despite the advances in the field, the fundamental aspects underlying enzyme-powered self-propulsion have rarely been studied. In this work, we select four enzymes (urease, acetylcholinesterase, glucose oxidase, and aldolase) to be attached on silica microcapsules and study how their turnover number and

Cover Dalton Transactions on the 31P NMR of trans-platinum(II) complexes

We report a combined experimental–theoretical study on the 31P NMR chemical shift for a number of trans-platinum(II) complexes. Validity and reliability of the 31P NMR chemical shift calculations are examined by comparing with the experimental data. A successful computational protocol for the accurate prediction of the 31P NMR chemical shifts was established for trans-[PtCl2(dma)PPh3] (dma

The oxo wall revisited: Cobalt oxo vs. cobalt oxyl

Terminal oxo complexes of late transition metals are frequently proposed reactive intermediates. However, they are scarcely known beyond Group?8. Using mass spectrometry, we prepared and characterized two such complexes: [(N4Py)CoIII(O)]+ (1) and [(N4Py)CoIV(O)]2+ (2). Infrared photodissociation spectroscopy revealed that the Co?O bond in 1 is rather strong, in accordance with its lack of chemical reactivity. On the contrary, 2 has a
