Financial technology, industrial ecology and energy efficiency.

To achieve peak carbon neutrality, it is necessary to transform energy structures, promote industrial ecology, and enhance energy efficiency. Employing provincial panel data from 2011-2020, we empirically investigate the impact of financial technology on energy efficiency and the role of industrial ecology in the development of financial technology to enhance energy efficiency. The findings reveal that financial technology can significantly enhance energy efficiency and promote it by improving industrial ecology.

N-doped carbon dots as the multifunctional fluorescent probe for mercury ion, glutathione and pH detection.

Recently, carbon dots (CDs) have exhibited promising applications in the fluorescence detection of various ions and biomolecules. In this work, one kind of nitrogen-doped CDs (N-CDs) with high fluorescence intensity was synthesized, characterized by transmission electron microscopy, x-ray diffraction, x-ray photoelectron spectroscopy, Fourier-transform infrared, UV-vis absorption spectra, and fluorescence spectra. The results show that the spherical and uniform N-CDs (quantum yield: 60.
