Hydrated V2O5 with unique physical and chemical characteristics has been widely used in various function devices, including solar cells, catalysts, electrochromic windows, supercapacitors, and batteries. Recently, it has attracted extensive attention because of the enormous potential for the high-performance aqueous zinc ion battery cathode. Although great progress has been made in developing applications of hydrated V2O5, little research focuses on improving current synthesis methods, which have disadvantages of massive energy consumption, tedious reaction time, and/or low efficiency. Herein, an improved synthesis method is developed for hydrated V2O5 nanoflakes according to the phenomenon that the reactions between V2O5 and peroxide can be dramatically accelerated with low-temperature heating. Porous hydrated V2O5 nanoflake gel was obtained from cheap raw materials at 40 °C in 30 min. It shows a high specific capacity, of 346.6 mAh/g, at 0.1 A/g; retains 55.2% of that at 20 A/g; and retains a specific capacity of 221.0 mAh/g after 1800 charging/discharging cycles at 1 A/g as an aqueous zinc ion battery cathode material. This work provides a highly facile and rapid synthesis method for hydrated V2O5, which may favor its applications in energy storage and other functional devices. [ABSTRACT FROM AUTHOR]

Abstract: Time-resolved luminescence detection technique using lanthanide chelates as luminescent probes or sensors is a highly sensitive and widely used tool for the luminescence detections of various biological and bioactive molecules. The essential of this technique is the developments of various functional luminescent probes or sensors that can selectively recognize the biological targets. In this work, a dual-chelating ligand N,N,N1,N1-{2,6-bis(3′-aminomethyl-1′-pyrazolyl)-4-[N,N-bis(2-picolyl)amino-methylenepyridine]} tetrakis(acetic acid) (BBATA) has been designed and synthesized. The luminescence of its Tb3+ chelate is very weak, but can be selectively and strongly enhanced upon reaction with Zn2+ ions. Thus a Tb3+ chelate-based luminescent chemosensor, BBATA-Tb3+, for highly selective and sensitive time-resolved luminescence detection of Zn2+ ions was developed. To confirm the utility of new chemosensor for the detection of intracellular Zn2+ ions, the performance of BBATA-Tb3+ as a chemosensor for time-resolved luminescent imaging detection of Zn2+ ions in living cells was investigated. The results demonstrated the efficacy and advantage of the new luminescent chemosensor for time-resolved luminescence detection of intracellular Zn2+ ions. [Copyright &y& Elsevier]
