Web23 mrt. 2024 · Ionic charge: When the atom loses or gains one or more electrons, the electric charge is generated (and an ion is formed). This electric charge generated on the ion is known as Ionic charge. When atoms gain electron/s, the negatively charged ion is formed, and when the atoms lose electron/s, the positively charged ion is formed. WebThe as-prepared Cu NCs showed strong green fluorescence (with a quantum yield as high as 33.6%) and high ion stability, and good antioxidant activity as well. The resultant Cu NCs were used for the detection of 4-aminoazobenzene (one of 24 kinds of prohibited textile compounds) in water with a minimum detection limit of 1.44 μM, which has good …
