Novikov, V. N. published an article in 2022, the title of the article was Upper bound of fragility from spatial fluctuations of shear modulus and boson peak in glasses.Name: Phenyl Salicylate And the article contains the following content:
It is shown that the normalized rms fluctuation of the shear modulus on the medium-range order scale in glasses correlates with fragility: the higher fragility, the smaller the fluctuation amplitude. The latter is calculated within the heterogeneous elasticity theory using the data on the boson peak in glasses. On a smaller scale corresponding to cooperative structural relaxation, the normalized rms fluctuation of the infinite-frequency shear modulus was estimated using the data on the decoupling of viscosity and diffusion in supercooled liquids These fluctuations are much smaller in amplitude, and, in contrast, they increase with increasing fragility. Extrapolation predicts intersection of both rms fluctuations and disappearing of the boson peak at the upper limit to fragility ′180. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).Name: Phenyl Salicylate
