Potassium 79-88 MHC class I polypeptide-related sequence A Homo sapiens 121-125 9878133-3 1999 The adsorbed cationic amphiphile molecules remaining on mica surfaces after rinsing with distilled water were found to be anchored to the surface by ion-exchange, replacing surface potassium and/or other cations. Potassium 181-190 MHC class I polypeptide-related sequence A Homo sapiens 56-60 9878133-4 1999 The ratio of adsorbed cationic amphiphile molecules with single alkyl chains to the maximum potassium ions on mica surface was estimated to be twice as large as that of amphiphiles having two alkyl chains. Potassium 92-101 MHC class I polypeptide-related sequence A Homo sapiens 110-114 9315692-3 1997 We show that the model protein, hexaarginine-tagged green fluorescent protein (GFP), binds to mica via its Arg-tag based on ion exchange of naturally occurring potassium cations. Potassium 160-169 MHC class I polypeptide-related sequence A Homo sapiens 94-98 35207588-7 2022 This paper presents three new foci for the hypothesis of life"s origins between mica sheets: (1) that potassium is essential for life"s origins on Earth; (2) that biotite mica has advantages over muscovite mica; and (3) that micaceous clay is a better environment than isolated mica for life"s origins. Potassium 102-111 MHC class I polypeptide-related sequence A Homo sapiens 278-282 31781711-6 2020 Then, we find that humidity improves the resistance of the layers to be squeezed-out and extends the range of loads in which the liquid behaves as a superlubricant, interpreted by an enhanced dissolution of the potassium ions on the mica leading to a larger surface charge. Potassium 211-220 MHC class I polypeptide-related sequence A Homo sapiens 233-237 31765512-4 2020 We were able to tune the strength of the mica-organothiol interactions by exchanging the potassium surface ions for copper ions.

Potassium 97-106 MHC class I polypeptide-related sequence A Homo sapiens 33-37 21740026-7 2011 Comparing collagen assembly on the two types of mica at different potassium concentrations revealed that potassium binds to the negatively charged mica surface and neutralizes it, thereby reducing the binding affinity of collagen and enhancing surface diffusion.

Potassium 0-9 MHC class I polypeptide-related sequence A Homo sapiens 53-57 30950624-2 2019 It was found that sodium ions did not show any bridging effect in this system; however, calcium, magnesium, and potassium all caused adsorption of the organic to the mica surface. Potassium 112-121 MHC class I polypeptide-related sequence A Homo sapiens 166-170 30111140-2 2018 Due to the underlying symmetry of the potassium ions on the mica surface, the contact layers prefer to adopt an incommensurate square or rhombic symmetry. Potassium 38-47 MHC class I polypeptide-related sequence A Homo sapiens 60-64 29961781-4 2018 Our results demonstrate the key role of the structure of the mica surfaces, specifically the positions of potassium (K+) ions, in determining the nature of sliding friction with monolayer lubricants, including the presence or absence of stick-slip dynamics. Potassium 106-115 MHC class I polypeptide-related sequence A Homo sapiens 61-65 24369856-2 2014 Although the epitaxially guided collagen assembly mediated by potassium ion on mica surface has been reported several times over these years, specific effects of anions in this field has never been surveyed and discussed before now. Potassium 62-71 MHC class I polypeptide-related sequence A Homo sapiens 79-83 30180643-2 2018 Mica muscovite is a particularly interesting material, because there exist fossil and experimental evidence for nonlinear excitations transporting localized energy and charge along the cation rows within the potassium layers.
