UV鈥揤is shows that the absorption peak of modified ATP is apparently red-shifted and the absorbance intensity of CQDs/ATP is higher than others. FT-IR and XPS show that the CQDs are immobilized on the surface of ATP through hydroxylation reaction. TEM shows that the average diameter of ...
The binding energy of B1s in XPS for boron substitution in the carbon lattice shows a peak ranging between 186.9 and 188.8 eV [308]. Additionally, the various boron oxides and carbides (BC2O, BCO2, B2O3, and BC3) formed on the carbon surface have B1s peaks ranging from 189.0 to ...
Hydrogen, as a clean energy carrier, is of great potential to be an alternative fuel in the future. Proton exchange membrane (PEM) water electrolysis is ha
Meanwhile, the X‐ray diffraction (XRD) patterns of the CDs prove a similar peak at around 23°, which can be attributed to the graphite (002) lattice spacing (Supplementary Fig. 9). X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FT-IR) spectra are employed to ...

Surgery followed by adjuvant chemotherapy is a reliable therapy for colon cancer, but is associated with side effects and risks. Recent advancements in nanobioengineering in the form of targeted nanoparticles, cubosomes, liposomes, nanosheets, nanorods,
The dominant strength of G peak indicates the graphitic structure nature of CDs in the study. The chemical composition of the prepared CDs is analyzed using X-ray photoelectron spectroscopy (XPS) analysis. As shown in Fig. 1c, results of full-scale XPS spectra analysis demonstrate that the ...
process demonstrated effective and efficient tuning of the overall electronic structure of the N-CQDs resulting in enhanced optical properties and performance as a nano-sensor. Introduction The demand for high-performance carbon quantum dots (CQDs) with a range of applications, including sensing has ...
Green-emissive carbon quantum dots (CQDs) were synthesized from pear juice via a facile, scalable, one-pot solvothermal process. The as-synthesized CQDs exhibit superior photocatalytic activity under visible-light irradiation owing to their efficient light absorption, electron transfer, and separation of...
