Abstract:
... Designing soy protein (SP)-based composite films with great toughness and high strength remains an intractable challenge. In this work, a facile strategy for preparing SP-based composite films by incorporating polyethyleneimine (PEI) as plasticizer and lignin-Ag nanoparticles (NPs) as green reinforcer is proposed. The fabricated films exhibit great toughness of 15.22 MJ m⁻³, high tensile strength ...

Abstract:
... The extracellular matrix (ECM) degradation of nucleus pulposus cells (NPCs) is mainly induced by metalloproteinases (MMPs). Zn²⁺ is an essential component of MMPs, but the effect of Zn²⁺ importers in controlling ECM metabolism remains unclear. The purpose of this research was to identify the involvement of Zn²⁺ importers in ECM degradation induced by inflammatory stimuli and excessive mechanical s ...

Abstract:
... The effect of external uniaxial strain on water dissociation on a reduced rutile TiO₂(110) surface has been theoretically studied using first-principles calculations. We find that when the tensile strain along [11̄0] is applied, the energy barrier of water dissociation substantially decreases with the increase of strain. In particular, water almost automatically dissociates when the strain is larg ...
