The BioColour Library

Coloration Technology, EarlyView.
Abstract The attraction of adopting natural and bio‐based colourants in applications has grown, but their use suffers from a lack of certification bodies, standards and reference data. In the BioColour project, we are developing an open database and tools for the characterisation, authentication and quality analysis of biocolourant sources ...

Síntese e caracterização estrutural do ligante isatina-3-(N4-benziltiossemicarbazona) e do seu complexo de mercúrio(II) Synthesis and structural characterization of the ligand isatin-3-(N4-benzylthiosemicarbazone) and its mercury(II) complex

Química Nova, 2010
The reaction of 4-(phenyl)thiosemicarbazide with isatin yielded a new ligand, isatin-3-(N4-benzylthiosemicarbazone). Isatin-3-(N4-benzylthiosemicarbazone) deprotonated in ethanol/KOH reacts with an ethanolic solution of Hg(NO3)2 to give a mercury complex.

Natural variation of the wheat root exudate metabolome and its influence on biological nitrification inhibition activity

Plant Biotechnology Journal, EarlyView.
Summary Excessive nitrogen use and low nitrogen use efficiency (NUE) in current agroecosystems are disrupting the global nitrogen cycle. Chemical inhibitors offer only temporary relief, while plant‐derived biological nitrification inhibitors (BNIs) remain safer but underexplored.

Hyperbranched Interpenetrating Hydrogen Bond Network (HIHBN) Proton Exchange Membrane for Fuel Cells Above 220 °C

Advanced Functional Materials, Volume 35, Issue 31, August 1, 2025.
A novel polymer electrolyte membrane with a hyperbranched interpenetrating hydrogen bond network structure is developed. The unique structure of the hyperbranched polymer contributes to a high glass transition temperature exceeding 400 °C, enabling its operation at elevated temperatures for fuel cell applications.
