Increasing pressure induces pronounced atomic densification, reduces free volume, and enhances short-range order through the stabilization of close-packed motifs, whereas rapid quenching traps excess free volume and structural disorder. The glass transition temperature increases from 410 K to 512 K, while the activation enthalpy rises from 128 to 798 kJ·mol⁻¹ as pressure increases from 0 to 40 GPa, indicating a substantial enhancement of kinetic constraints. Correspondingly, the fragility index evolves from approximately 10 at ambient pressure to nearly 27 at 40 GPa, marking a transition from a strong to a more fragile glass former. Uniaxial tensile simulations reveal that compression increases the elastic modulus by up to 28 % and significantly raises the yield stress, leading to higher stiffness but reduced ductility, whereas rapid quenching promotes heterogeneous plastic flow characterized by localized shear-band formation. Atomic-scale analyses confirm that structural compaction suppresses the nucleation of shear transformation zones and limits local rejuvenation.

This paper synthesises phosphoric acid functionalized graphene oxide (PGO) using the Hummers' method and studies its adsorption performance and mechanism for La (III). The adsorption efficiency is evaluated through single/multi-component static adsorption experiments, combined with techniques such as XPS, FTIR, BET, and TGA to elucidate the mechanism. Experimental results show that the maximum adsorption capacity of PGO reaches equilibrium within 60 min at pH = 6, with a temperature of 35 °C and a concentration of 100 mg/L, achieving an adsorption rate as high as 78.9 %. The maximum adsorption capacity determined by Langmuir fitting is 742.796 mg · g-1. More importantly, PGO maintains an acceptable recovery efficiency for La(III) under typical interfering substances or different water matrices. Statistical physics calculations indicate that adsorption possesses thermodynamic characteristics of spontaneity, exothermicity, and increased randomness. Isothermal and kinetic fitting confirm that surface reaction-controlled chemical adsorption is the primary mechanism. Spectral analysis clarifies that phosphate groups (P<img>O, O–H) are at the core of La(III) adsorption, while oxygen-containing and possibly nitrogen-containing functional groups in the graphene substrate synergistically enhance the efficiency, achieving effective adsorption.
