Aluminum dispersed bamboo activated carbon production for effective removal of Ciprofloxacin hydrochloride antibiotics: Optimization and mechanism study.

The central composite rotatable design (CCD) of response surface methodology (RSM) was used to optimize aluminum dispersed bamboo activated carbon preparation. The independent variables selected for optimization are activating agent (AlCl) concentration (mol/L), activation temperature (°C), and activation time (min.).

Aqueous Synthesis for Highly Emissive 3-Mercaptopropionic Acid-Capped AIZS Quantum Dots.

Highly fluorescent and color tunable AgInS (AIS) and (AgInS)(ZnS) (AIZS) quantum dots (QDs) were prepared via a facile aqueous-phase synthesis using AgNO, In(NO), Zn(OAc), and NaS as precursors and 3-mercaptopropionic acid (3-MPA) as ligand. Produced AIZS QDs exhibit a small diameter (ca. 2.

High performance Ce-doped ZnO nanorods for sunlight-driven photocatalysis.

Ce-doped ZnO (ZnO:Ce) nanorods have been prepared through a solvothermal method and the effects of Ce-doping on the structural, optical and electronic properties of ZnO rods were studied. ZnO:Ce rods were characterized by XRD, SEM, TEM, XPS, BET, DRS and Raman spectroscopy. 5% Ce-doped ZnO rods with an average length of 130 nm and a diameter of 23 nm exhibit the highest photocatalytic activity for the degradation of the Orange II dye under solar light irradiation.

Insight of ZnS nanoparticles contribution in different biological uses.

Objectives: To evaluate the contributions of the some quantum dots in different biological uses in order to valorizes such nanomaterials for further applications.

Methods: Zinc sulfide ZnS nanoparticles were synthesized in aqueous medium at pH constant, the obtained nanoparticles has been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier Transform Infra-red (FTIR) spectroscopies. Zinc sulfide nanoparticles were screened for their antibacterial and antifungal profiling and tested for antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl radical (OH) and hydrogen peroxide (H2O2) scavenging activity, ferric reducing power (FRP) assay and ferrous ion chelating (FIC) methods.

A facile method for the preparation of bifunctional Mn:ZnS/ZnS/Fe3O4 magnetic and fluorescent nanocrystals.

Bifunctional magnetic and fluorescent core/shell/shell Mn:ZnS/ZnS/Fe3O4 nanocrystals were synthesized in a basic aqueous solution using 3-mercaptopropionic acid (MPA) as a capping ligand. The structural and optical properties of the heterostructures were characterized by X-ray diffraction (XRD), dynamic light scattering (DLS), transmission electron microscopy (TEM), UV-vis spectroscopy and photoluminescence (PL) spectroscopy. The PL spectra of Mn:ZnS/ZnS/Fe3O4 quantum dots (QDs) showed marked visible emission around 584 nm related to the (4)T1 → (6)A1 Mn(2+) transition.
