Effect of Micro- and Nano-Zeolite/Silica Fume on the Mechanical and Durability Characteristics of Reactive Powder Concrete [PDF]

JES: Journal of Engineering Sciences
Silica fume is an essential additive in Reactive Powder Concrete (RPC), as it promotes hydration and densifies the microstructure. In this research, silica fume was partially or fully replaceded with zeolite, introducing a novel 1:1 calcinated zeolite ...

Biomimetic Core–Shell Liposome Nanoparticles Deplete Lipoproteins and Enhance the Purity of Extracellular Vesicles from Human Blood

Advanced Functional Materials, EarlyView.
Lipoprotein‐mimicking nanoparticles (SL‐NPs), comprising Fe3O4@SiO2 cores coated with liposomal bilayers, selectively capture lipoproteins through protein corona formation. The resulting SL‐NP‐lipoprotein complexes can be removed by low‐speed centrifugation, thereby enhancing the purity of small extracellular vesicles (sEVs) isolated from human serum ...
