The detection was based on the disruption of the orientation of LCs, triggered due to surface reaction between aldehyde groups and surface amine groups which resulted in the formation of imine bonds. The detection limit of this sensor was 1 ppmv, depending on the amine groups density at the ...
This rotation has an analogy in the plastic deformation by single slip of metallic monocrystals. This mechanism was explained and quantified by Yang et al.17 for the arapaima scales and modeled by molecular dynamics. On the other hand, the rotation away from the direction of loading, for ...
Examples of polycrystals include ice, many metal samples, and ceramics. Even less structure is displayed by amorphous solids, which have disordered internal structure. An example of an amorphous solid is glass, which may resemble a crystal when faceted, yet isn't one. Chemical Bonds The types o...
