Core-shell silica-coated Fe(0) nanoparticles (Fe@SiO2) were prepared in one-step synthesis by aqueous reduction combined with modified Stöber method. The as-prepared Fe@SiO2 were then used for simultaneous removal of Cr(VI) and Cd(II) from aqueous solution. Batch tests indicated that Fe@SiO2 exhibited high removal capacity toward Cr(VI) and Cd(II). Cr(VI) was removed by Fe@SiO2 through reductio...

16 nm-SiO2-FITC NPs production was performed in one step by adding a solution of 5 mL of fluorescent organosilane solution previously prepared mixed with 240 mL of ethanol 20 and 5 mL of TEOS into a 2 L round bottom flask containing 650 mL of EtOH, 2.4 mL of water and 24.1 mL of ammonia. The solution was let to react overnight at room temperature (RT) in the dark. 16 nm-SiO2-FITC NPs were purif...

We report the synthesis, characterization, and application of Prussian blue (PB) functionalized CaMoO4:Eu@SiO2@Au nanorod hybrid nanoparticles (HNPs), with multimodal capabilities such as fluorescence imaging, surface-enhanced Raman spectroscopy (SERS) detection and photothermal therapy (PTT). The average size of CaMoO4:Eu@SiO2 NPs was 206 nm. The HNPs are highly dispersible in water for severa...

Titanium dioxide (TiO2) displays photocatalytic behavior under near-ultraviolet (UV) illumination. In another scientific field, it is well understood that the excitation of localized plasmon polaritons on the surface of silver (Ag) nanoparticles (NPs) causes a tremendous increase of the near-field amplitude at well-defined wavelengths in the near UV. The exact resonance wavelength depends on th...

We report on a one-step synthesis of conjugated polymer (CP) embedded silica nanoparticles (NPs) with a SiO2@CP@SiO2 structure by combination of a precipitation method and a modified Stöber approach. Four types of CPs are employed to demonstrate the versatility of the developed strategy, yielding fluorescent silica NPs with emission across the visible spectrum. Field emission transmission elect...

Here a luminescent hybrid nanostructure based on functionalized quantum dots (QDs) is used as a fluorescent imaging agent able to target selectively mitochondria thanks to the molecular recognition of the translocator protein (TSPO). The selective targeting of such an 18 kDa protein mainly located in the outer mitochondrial membrane and overexpressed in several pathological states including neu...

Effects of the suspended titanium dioxide nanoparticles (TiO2 NPs, 50 mg/L) on the cake layer formation in a submerged MBR were systematically investigated. With nanometer sizes, TiO2 NPs were found to aggravate membrane pore blocking but postpone cake layer fouling. TiO2 NPs showed obvious effects on the structure and the distribution of the organic and the inorganic compounds in cake layer. C...

Now, enticing systematic civic since everywhere the world is used in green synthesis and benefit of simple eco-friendly with an emergent method producing nanoparticles (NPs). The aim a single slope basin solar still (SBSS) has been synthesized using Silicon dioxide (SiO2) (NPs)/leaf extract Jatropha curcas L. (JCL) productivity enhancements to evaluation for photocatalytic treatment system. SiO...

In this paper, we investigated the functional imaging properties of magnetic microspheres composed of magnetic core and CdTe quantum dots in the silica shell functionalized with folic acid (FA). The preparation procedure included the preparation of chitosan-coated Fe3O4 nanoparticles (CS-coated Fe3O4 NPs) prepared by a one-pot solvothermal method, the reaction between carboxylic and amino group...
