- The resulting materials show strong chemical reactivity, making them useful in applications such as catalysts, adsorbents, and nanoreactors.
Article Abstract
Silica@carbon core-shell spheres have been synthesized via a hydrothermal carbonization procedure with glucose as the carbon precursor and silica spheres as the cores. Such SiO(2)@C core-shell spheres can be further used as templates to produce SiO(2)@C@SiO(2), and SiO(2)@SiO(2) spheres with a vacant region in two SiO(2) shells, noble-metal nanoparticle loaded SiO(2)@C core-shell spheres, and hollow carbon capsules through different follow-up processes. The obtained core-shell materials possess remarkable chemical reactivity in reducing noble-metal ions to nanoparticles, e.g., platinum. These unique core-shell spherical composites could find applications in catalyst supports, adsorbents, encapsulation, nanoreactors, and reaction templates.

Protein-nanoparticle interactions and the resulting corona formation play crucial roles in the behavior and functionality of nanoparticles in biological environments. In this study, we present a comprehensive analysis of protein corona formation with superfolder green fluorescent protein (sfGFP) and bovine serum albumin in silica nanoparticle dispersions using small-angle X-ray scattering (SAXS) and dynamic light scattering (DLS). For the first time, we subtracted the scattering of individual proteins in solution and individual nanoparticles from the protein-nanoparticle complexes.

Flexible surface-enhanced Raman scattering (SERS) sensors offer a promising solution for the rapid in situ monitoring of food safety. The sensor's capability to furnish quantitative detection and retain recyclability is crucial in practical applications. This study proposes a self-cleaning flexible SERS sensor, augmented with an intelligent algorithm designed for expeditious in situ and non-destructive thiram detection on apples.

The SnO@BiO core-shell heterojunction structure was designed and synthesized via a hydrothermal method, and the structure and morphology of the synthesized samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). Based on the conclusions from XRD and SEM, it can be observed that as the hydrothermal temperature increases, the content of BiO coated on the surface of SnO spheres gradually increases, and the diameter of BiO nanoparticles also increases. At a hydrothermal temperature of 160 °C, the SnO spheres are fully coated with BiO nanoparticles.

Photocatalytic technology for removing organic dye pollutants has gained considerable attention because of its ability to harness abundant solar energy without requiring additional chemical reagents. In this context, YF spheres doped with Yb, Er, Tm (YF) are synthesized using a hydrothermal method and are subsequently coated with a layer of graphitic carbon nitride (g-CN) with Au nanoparticles (NPs) adsorbed onto the surface to create a core-shell structure, designated as YF: Yb, Er, Tm@CN-Au (abbreviated as YF@CN-Au). The core-shell composites demonstrate remarkable stability, broadband absorption, and exceptional photocatalytic activity across the ultraviolet (UV) to near-infrared (NIR) spectral range.

Heterostructures comprise two or more different semiconducting materials stacked either as co-assemblies or self-sorted based on their dynamics of aggregates. However, self-sorting in heterostructures is rather significant in improving the short exciton diffusion length and charge separation. Despite small organic molecules being known for their self-sorting nature, macrocyclic are hitherto unknown owing to unrestrained assemblies from extended π-conjugated systems.
