A novel fluorescence sensor for successive detection of Cu2+ and Fe3+ ions has been synthesized and characterized. The sensor displays aggregation-induced emission enhancement characteristics and high selectivity towards Cu2+ ions. It also has the ability for rapid identification of Cu2+ and pH sensitivity.
A novel fluorescence sensor for successive detection of Cu2+ and Fe3+ based on anti-B18H22 derivative which possesses 5-hydroxyisoquinoline as an ionophore was synthesized via a one-pot and its structure and photophysical properties were characterized by NMR, HRMS, FTIR, UV-vis, PL and theoretical calculation. The fluorophore displays two emission peaks at 460 nm and 670 nm in THF solution coming from the emission of the locally excited state and intramolecular charge transfer fluorescence, respectively. The complex exhibited obvious aggregation-induced emission enhancement (AIEE) characteristics in THF/H2O solution by increasing the aqueous concentration from 70% to 95%. The AIEE molecules showed a high selectivity towards Cu2+ over other metal ions by forming a 2:1 metal-to-ligand complex in THF/H2O (fw = 20%) solution, the fluorescence intensity increased as a linear function of the Cu2+ concentration at 460 nm due to the inhibition of PET effect. The fluorescent emission was quenched linearly by the addition of Fe3+, which provides a method for successive determination of Cu2+ and Fe3+ based on 'off-on-off' fluorescence of the fluorescent. The detection limit of Cu2+ and Fe3+ was 5.7 x 10(-6) M and 7.2 x 10(-5) M respectively. Morever, a rapid identification of Cu2+ in the aqueous solution by naked eyes can be realized. In addition, the molecules were pH-sensitive, the fluorescence quenching can be observed in strongly alkaline environment. The method has been applied to the determination of copper ions in water samples with satisfactory results.

Unloading creep of soft clay and long-term uplift bearing characteristics of suction caisson foundation

Zhu Wen-bo, Dai Guo-liang, Wang Bo-chen, Gong Wei-ming, Wang Hai-bo, Zhang Yu

Summary: This paper investigates the unloading creep mechanism of soft clay and the long-term uplift bearing characteristics of suction caisson foundation. Experimental tests are conducted to study the variation of axial strain with time and the deformation mechanism of soft clay under different confining pressures. Results show that unloading creep deformation of soil can be ignored under low deviator stress, but becomes more significant as the unloading deviator stress increases. A stress-dependent creep model is proposed to describe the unloading creep of soft clay, and a three-dimensional constitutive model is developed for analyzing the long-term uplift capacity of suction caisson foundations. The model is validated with experimental results.
