Oxygen Vacancy‐Enriched Platinum Single‐Atom Nanozyme Wrapped in Nanoislands: Unlocking Catalytic Activity and Reprogramming Redox Microenvironment for Osteonecrosis Repair

Advanced Science, EarlyView.
CeO2‐x/Pt single‐atom nano‐island is constructed via low‐temperature reduction, featuring abundant oxygen vacancies and an island–sea structure. It delivers outstanding multi‐enzyme‐mimetic activity and ROS‐scavenging efficiency. Density functional theory reveals optimized electronic structures and reaction pathways.

Pathological Mechanism‐Inspired Biomimetic Nano‐Senotherapy for Reversing Experimental Atherosclerosis in ApoE−/− Mice

Advanced Science, EarlyView.
The biomimetic self‐assembly nanomedicine reversing atherosclerosis via senotherapy strategy. ABSTRACT The greatest challenge in atherosclerosis (AS) management lies in achieving lesion reversal, not merely slowing progression. Senescent cell accumulation—driven by continuous generation and apoptotic resistance—perpetuates plaque pathology and ...

The zeta potential of mineral fibres

Journal of Hazardous Materials, 2014
For the first time, the zeta (ξ) potential of pathogenic mineral fibres (chrysotiles, amphiboles and erionite) was systematically investigated to shed light on the relationship between surface reactivity and fibre pathogenicity. A general model explaining the zeta potential of chrysotile, amphiboles and erionite has been postulated. In double distilled

Zeta Potential Measurements on Passive Metals

Journal of Colloid and Interface Science, 1995
In this study, one shows that the zeta potential can be determined on stainless steel sheet surfaces by streaming potential measurements, These surfaces are in fact covered with a thin oxyhydroxide film known as ''the passive film.'' Zeta potential depends on the solution composition and the surface final conditions, The zeta potentials on AISI 304 ...

Zeta Potential Measurement

2010
This chapter describes a method for the measurement of the electrostatic potential at the electrical double layer surrounding a nanoparticle in solution. This is referred to as the zeta potential. Nanoparticles with a zeta potential between -10 and +10 mV are considered approximately neutral, while nanoparticles with zeta potentials of greater than +30

The zeta-potential of cement

Cement and Concrete Research, 1985
Abstract Zeta-potential measurements provide new informations on cement hydration, gel structure formation and the effects of chemical admixtures. The formation and significance of a zeta-potential of cement in aqueous suspension is discussed with respect to the hydration of cement and some new data on the zeta-potential of cement and fly ash under ...

Zeta potential of phosphors

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1995
Abstract The zeta potentials of several oxide, sulfide, and oxysulfide phosphors were measured in isopropyl alcohol (IPA) and IPA containing dissolved nitrate salts and water. The zeta potentials of phosphors in IPA without dissolved salts are negative.
