Keto–enol equilibrium: stable tautomers of ortho-, meta-, and para-hydroquinones in large aromatics
Keto–enol tautomerism of hydroquinones was studied for fused aromatic compounds. For larger fused aromatic compounds the dione tautomer was the stable form. These experimental results were corroborated by calculations.

Nanoarchitectonics of highly dispersed polythiophene on paper for accurate quantitative detection of metal ions
Paper fibers allow the high dispersion of a fluorescent polythiophene chemosensor for the suppression of aggregation-induced quenching, which is applied to the solid-state fluorescent quantitative sensing of metal ions using imaging analysis and pattern recognition techniques.

Simple potentiometry and cyclic voltammetry techniques for sensing Hg2+ ions in water using a promising flower-shaped WS2-WO3/poly-2-aminobenzene-1-thiol nanocomposite thin film electrode
The WS2-WO3/P2ABT nanocomposite sensor for Hg2+ ions uses both the cyclic voltammetry (three-electrode cell) and the simple potentiometric (two-electrode cell) techniques. The calibration curve yields a Nernstian slope of 33.0 mV decade−1 with a sensitivity of 2.4 μA M−1.

Novel pyrazoline and pyrazole “turn on” fluorescent sensors selective for Zn2+/Cd2+ at λem 480 nm and Fe3+/Fe2+ at λem 465 nm in MeCN
A small series of simple pyrazoline and pyrazole based sensors, all derived from the same chalcone precursors, were synthesised, characterised and screened for their fluorescence “turn on” properties in the presence of multiple metals.
