Moreover, the sensing mechanism has been assessed using Stern-Volmer's equation and fluorescence lifetime experiments showing the simultaneous occurrence of photoinduced electron transfer and the inner filter effect. This chromium sensor has also been employed to assess the contamination level in real...
After seven years of hard work, the CR450 train has achieved remarkable results: it is faster, with a test speed of 450 kilometers per hour and an operational speed of 400 kilometers per hour; it is safer, with shorter braking distances and better operational stability, maintaining a bra...

HydrogelAdsorptionFluorescentIn this study, a novel nitrogen-doped carbon quantum dot/oxidized gum arabic-gelatin-based fluorescent probe (NAH) was prepared using gelatin (GL) and gum arabic (AG) biomolecules. The primary network structure of this hydrogel consisted of polyacrylamide (PAM), while ...
To overcome that current carbon dots (CDs) can just detect chromium ions in a single valence state, bright N and S co-doped carbon dots (N, S-CDs) were synthesized to respond Cr (III) and Cr (VI) at same time. Sample N, S-CDs with isothiocyanate functional groups were created...
