    Hidden spatiotemporal sequence in transition to shear band in amorphous solids by Zeng-Yu Yang, Yun-Jiang Wang, Lan-Hong Dai

    Published 2022-06-01
    “…Localization of plastic flow into a narrow shear band is a fundamental and ubiquitous nonequilibrium phenomenon in amorphous solids. Because of the intrinsic entangling of three types of elementary local atomic motion—shear, dilatation, and rotation—the precise physical process of shear band emergence is still an enigma. …”

    Amorphous solid dispersion to enhance the bioavailability of poorly soluble drug by Tee, Hui Shi

    Published 2023
    “…In this study, a therapeutic DES (THEDES) based on ibuprofen and menthol was synthesised and mixed with polyvinylpyrrolidone (PVP K30) as the polymer matrix to form amorphous solid dispersion (ASD). The payload of ibuprofen was analysed by high-performance liquid chromatography (HPLC). …”

In the present work, we also compare the shear modulus for the inhomogeneous solid having localized density profiles with the corresponding elastic response for the uniform liquid in the limit of high frequencies.…”
