“…72,73 Phosphorus compounds including ODP, OPA, H 3 PO 4 , PC and DTPMP were selectively bound to the clay lumen surface through bidentate or tridentate Al-O-P bonds. [74][75][76][77][78] Organic molecules that can establish Al-O-C bonds on the clay lumen surface have been found to include dopamine and ionic liquids HM. [79][80][81] Arylboronic acids, such as PBA and PA, have been proposed as another new tool to selectively decorate the clay lumen by establishing Al-O-B bonds.…”

Some phyllosilicate compounds have the ability of spontaneous scrolling because of the size mismatch between the covalently bounded metal oxide and silica sheets. Their unique structure and high theoretically predicted Young's modulus (around 210–230 GPa) induce phyllosilicates’ application as reinforcing fillers. However, previous nanomechanical experiments with individual phyllosilicate nanoscrolls are in poor agreement with theory. The main reason for this is the low accuracy of experiments, which leads to large measurement errors compared to measured average values. Here, the study of the mechanical properties of synthetic (Mg1–xNix)3Si2O5(OH)4 phyllosilicates is reported by testing a suspended nanoobject (a nanobridge) with an atomic force microscope (AFM). The Young's modulus of corresponding phyllosilicate model layers is also calculated by means of the density functional theory (DFT). The original AFM approach makes it possible to account for the probe slipping off the nanobridge and determine its boundary conditions. The measured Young's modulus values are considered within the models of surface tension and shear strain contributions. The shear strain appears to have a decisive impact on the measured Young's modulus (from 150 ± 70 GPa to 200 ± 210 GPa) and its spread.
