A facile ultrasonic route for the fabrication of graphene quantum dots (GQDs) with upconverted emission is presented. The as-prepared GQDs exhibit an excitation-independent downconversion and upconversion photoluminescent (PL) behavior, complex photocatalysts (rutile TiO(2)/GQD anatase systems) were designed to harness visible spectrum sunlight. It interesting that photocatalytic rate rutile system ca. 9 times larger than under light (λ > 420 nm) irradiation in degradation methylene blue.
Abstract A facile method based on capillarity‐assisted assembly is used to fabricate high‐performance surface‐enhanced Raman scattering (SERS) substrates employing clean Au nanoparticles (NPs). This better than micro‐channel way because the former may supply large‐area uniform and overcome uneven radial distribution. Such densely‐arranged of NPs exhibits high reproducibility large enhancement factors 3 × 10 , arising from strong electromagnetic field coupling induced by adjacent NPs. The...
In this paper, we have presented a novel strategy to fabricate Fe-doped carbon quantum dots (Fe-CQDs) for dopamine sensing applications. The Fe-CQDs are obtained by one step hydrothermal carbonization, using ethylenediamine tetraacetic acid salts and ferric nitrate as the iron source, which simultaneously incorporates Fe (dopamine-bonding site) luminescent (fluorophores). added containing catechol groups might form complexes with ions (doped in CQDs) due coordination. Subsequently, was...
Nanomaterials have offered an opportunity for molecular imprinting to extract templates easily and achieve large binding capacity. In this paper, silicon nanowires were employed as the reinforcement material in protein with dopamine monomer bovine hemoglobin template molecule. experiments, imprinted showed fast adsorption kinetics (took up 75% of equilibrium amount during only 5 min), significant selectivity capacity (213.7 mg g−1) protein. Furthermore, stability regeneration also...
A well-designed turn-on sensor has been constructed and used for the assay of oxytetracycline hydrochloride in real milk samples.
Fe-CDs with peroxidase-like activities have been fabricated and applied for H<sub>2</sub>O<sub>2</sub> glucose detection.
Abstract Standard procedures for determining 15 N in the NH 4 + fraction of 2 M KCl soil extracts convert to prior isotope‐ratio mass spectrometry. We developed a new gas‐phase method by producing O. Producing O means that atmospheric contamination at natural abundance is not problem. The more sensitive than other methods lower enrichments, and as accurate precise methods. Nitrous oxide produced by‐product during oxidation alkaline OBr − . reaction catalyzed Cu 2+ pH‐dependent. best...
