Moreover, the optimal doping amount of Ti was ambiguous. Therefore, in this work, the effect of Ti on the microstructures and superconducting properties of the Nb<sub>3</sub>Sn superconductor was systematically investigated using the powder metallurgy method. The results showed that Ti doping could increase the average Sn content and reduce the concentration gradient of Sn in the Nb<sub>3</sub>Sn layer. In addition, the grains of Nb<sub>3</sub>Sn were appropriately refined. On such a basis, the irreversible field (<em>B<sub>irr</sub></em>) and the pinning force density (<em>F<sub>p</sub></em>) and, thereby, the critical current density (<em>J<sub>c</sub></em>) at high magnetic fields were substantially affected by Ti doping.

The coated structures exhibited the ability to adsorb the organic pollutant and clean the contaminated water. We observe ∼78 % degradation efficiency for MB and ∼48 % for MO in dye concentrations of 10 mg/100 ml. A colorimetric detection method was used for real-time detection of degradation efficacy.
