Highly fluorescent sulfur quantum dots could be rapidly and massively synthesized from inexpensive elemental under a pure O<sub>2</sub> atmosphere.
The direct utilization of abundant and cheap elemental sulfur (S) to synthesize quantum dots (SQDs) with satisfactory yield photoluminescence (PLQY) remains a big challenge. Here, we report simple effective method for mass-producible synthesis ultrabright fluorescent SQDs based on one-pot solvothermal treatment S-ethylenediamine (S-EDA) solution. PLQY synthesized the corresponding S-to-SQDs conversion efficiency (CE) can reach as high 87.8% 15.9%, respectively, both which are highest values...
The development of low-cost adsorbent with excellent adsorption property remains a big challenge. Herein, the functionalization natural peach gum polysaccharide (PGP) multiple amine groups for removal toxic Cr(VI) ions from water was studied. obtained PGP-NH2 gel exhibited high-removal efficiency (>99.5%) toward ions, especially relatively low initial concentration (≤250 mg/L). influences pH, ionic strength, contact time, concentration, and temperature on were systematically investigated....
Selenium nanoparticles (SeNPs) exhibit great potential across a spectrum of applications, yet the development effective methods for their large-scale preparation remains an emerging field. Herein, we propose method to produce SeNPs using nontoxic bulk selenium powder. By dissolving powder in ethylenediamine (EDA) create homogeneous Se–EDA solution, can be easily formed by adding this solution water. The obtained small and uniform size, fine water dispersibility, low cytotoxicity, also...
This study introduces Magnetic Starch (MAST), an innovative material designed for the efficient and rapid removal of water contaminants. MAST is synthesized by integrating polyethyleneimine magnetic Fe3O4 nanoparticles into a starch composite. It exhibits saturation magnetization 7.3 emu/g functional surface area 3.55 m² g−1. MAST's amine group density 12.03 mmol/g, indicating strong affinity pollutants. Notably, demonstrates exceptional adsorption capacities various hazardous substances,...
The straightforward preparation of fluorescent sulfur quantum dots (SQDs) with good photostability and biocompatibility multifunction remains a challenge. Herein, simple method to improve the performance SQDs is reported, that is, using hyperbranched polyglycerol (HPG) as ligand direct synthesis dendritic HPG-SQD nanocomposites from cheap elemental sulfur. Thanks protection HPG, HPG-SQDs show much better compared widely reported polyethylene glycol (PEG) ligand-capped (PEG-SQDs). In...
The creation of fluorescent nanoprobes capable both detecting and neutralizing reactive oxygen species (ROS) has remained an elusive goal in biomedical research. In this study, we present a straightforward one-pot solvothermal approach to synthesize elemental selenium quantum dots (SeQDs), novel class metal-free nanomaterials, directly from bulk using selenium-ethylenediamine precursor. When optimized at 180 °C for 4.5 h, the SeQDs achieve impressive product yield 7.1 ± 0.5% single-photon...
Abstract Sulfur nanoparticles (SNPs) have shown good potential in numerous fields due to their unique composition and properties. However, the direct utilization of abundant inexpensive elemental sulfur for large‐scale fabrication high‐quality SNPs is still its infancy. Herein, a simple one‐pot approach preparation presented, gram‐scale can be readily prepared one batch laboratory. By adding sulfur‐ethylenediamine precursor acidic chitosan (CS) solution, chitosan‐capped (CS‐SNPs) formed...
