One-pot solvothermal synthesis of ZnCoS/carbon nanosphere composites: tuning carbon content for high-performance supercapacitor electrodes.

The impact of carbon loading in binary transition metal sulphide-based nanocomposites for designing high-performance supercapacitor electrodes requires a comprehensive investigation. In this work, a series of nanostructured materials-including pristine ZnCoS, carbonaceous nanospheres (CNS), and a set of dextrose-derived ZnCoS/CNS nanocomposites (labelled as ZnCoS/CNS (D), where '' denotes the mole ratio of dextrose (D) to the Zn precursor and takes values of 1, 2, 5, and 10)-were synthesized a facile, one-pot, solvothermal route. Notably, the ZnCoS/CNS (D2) nanocomposite exhibited a heterogeneous and porous nano/microsphere morphology with efficient integration of ZnCoS and CNS.

Carbohydrazone/Thiocarbohydrazone-Based Dual-Responsive Probes for Highly Selective Detection of Cu/Fe Cations and F/ClO Anions, and Their Application in Bioimaging of Live Cells and Zebrafish Larvae.

Four dual-responsive probe molecules 1,5-bis(thiophene-2-carbaldehyde)carbohydrazone (R1), 1,5-bis(thiophene-2-carbaldehyde)thiocarbohydrazone (R2), 1,5-bis(indole-3-carbaldehyde)carbohydrazone (R3), and 1,5-bis(indole-3-carbaldehyde)thiocarbohydrazone (R4) were synthesized, characterized, and investigated for their sensing efficacy. The initial sensing behavior of the probes was tested by colorimetric signaling, followed by spectral and theoretical techniques, which supported the dual-sensing ability of the selected inorganic ions. The probes exhibited highly selective optical recognition for Cu/Fe cations and F/ClO anions compared to the tested cations and anions.
