Article Abstract
CdS-ZnS core-shell quantum dots (QDs) were synthesized with three different types of capping agents. To achieve the best fluorescence emission efficiency the factors of pH, temperature, and the ratio of CdS-ZnS QDs to the capping agent, were investigated via a full factorial experimental design. The best fluorescence intensity was obtained at pH 8, temperature 80°C, and a ratio of CdS-ZnS to the capping agent of 1:1.5. CdS-ZnS QDs were fabricated with different capping agents: thioglycolic acid, mercaptosuccinic acid, and L-cysteine. The interaction of the synthesized QDs with metals ions Gd, La, Th, Pr, Eu, and Ce was investigated. The results showed that europium (III) ions significantly reduced the fluorescence emission intensity of QDs. Additionally, the fluorescence intensity decreases linearly with increasing europium (III) ion concentration. The detection limits for measuring europium (III) ions were obtained 1.56 × 10 a linear dynamic range of 7.8 × 10 to 5.0 × 10 M. Also, the fluorescence quantum yields for CdS-ZnS@LCY, CdS-ZnS@MSA and CdS-ZnS@TGA were obtained 4.23, 2.32 and 2.64, respectively. The binding constants (K) of CdS-ZnS@TGA, CdS-ZnS@MSA, and CdS-ZnS@LCY QDs with Eu were investigated and results were found as 194, 178, and 929, respectively. The Stern-Volmer constant and R were investigated for the above ions with QDs.

This review describes new strategies in the use of multifunctional organic alkalizers (OA) for the fabrication of advanced functional materials. OA facilitate solubilization and delivery of poorly solubilized drugs through the formation of drug-OA complexes and supramolecular gels. OA are applied for the synthesis of materials for biomedical, energy storage, catalytic, photovoltaic, sensor, and electronic applications.

The preparation of multimodal nanoparticles by capping magnetic iron oxide nanoparticles (IONPs) with functional organic molecules is a major area of research for biomedical applications. Conjugation reactions, such as carbodiimide coupling and the highly selective class of reactions known as "click chemistry", have been instrumental in tailoring the ligand layers of IONPs to produce functional biomedical nanomaterials. However, few studies report the controls performed to determine if the loading of molecules onto IONPs is due to the proposed coupling reaction(s) employed, or some other unknown interaction with the IONP surface.

The green synthesis method is a significant approach that offers several advantages, including simplicity, rapidity, and cost-effectiveness in the synthesis of nanoparticles. Iron nanoparticles were synthesized in this work using waste banana peel extract as a capping and reducing agent. The produced nanoparticles were then subjected to a number of characterization procedures, such as Raman spectroscopy, X-ray diffractometry (XRD), zeta potential analysis, Fourier transform infrared (FT-IR) spectroscopy, ultraviolet-visible (UV-VIS) absorption spectroscopy, field scanning electron microscopy (FE-SEM), energy dispersive X-ray analysis (EDX), and thermogravimetric analysis (TGA).

Aluminum nanoparticles (Al NPs) were synthesized via catalyzed thermal reduction of an aluminum precursor in the presence of a capping ligand. A systematic study was conducted to examine the effect of dilution on nanoparticle synthesis by varying the volume of anhydrous toluene across four dilution factors while maintaining constant molar quantities of the aluminum precursor, catalyst, and ligand. This methodology is relevant for scale-up processes, where more dilute conditions can mitigate nanoparticle reactivity and enhance safety.
