Journal ArticleDOI
SERS and Raman imaging as a new tool to monitor dyeing on textile fibres
TL;DR: In this paper, surface enhanced Raman scattering (SERS) and Raman imaging can be used with advantage in the monitoring of textile dyeing process using Ag containing linen fibres stained with methylene blue (MB).
Journal ArticleDOI

Paula C. R. Soares-Santos,Rute A. S. Ferreira,Tito Trindade,Luís D. Carlos,Helena I. S. Nogueira +4 more
TL;DR: In this paper, the terbium complexes of Tb(III) with 2-aminonicotinic (Hanic), thiosalicylic (Htsal) and anthranilic (Hant) acids were synthesized and characterized by vibrational spectroscopy and elemental analysis.
Journal ArticleDOI
Pyridine-carboxylate complexes of platinum. Effect of N,O-chelate formation on model bifunctional DNA-DNA and DNA-protein interactions.
Susana Quintal,Yun Qu,Adoración G. Quiroga,Joseph J. Moniodis,Helena I. S. Nogueira,Nicholas Farrell +5 more
TL;DR: To ascertain by model chemistry the feasibility of formation of ternary DNA-Pt-protein adducts in biology, platinum complexes containing bidentate pyridine-carboxylate and picEt ligands were reported on.
Journal ArticleDOI
Photoluminescent hybrid materials based on lanthanopolyoxotungstates and 3-hydroxypicolinic acid
Carlos M. Granadeiro,Rute A. S. Ferreira,Paula C. R. Soares-Santos,Luís D. Carlos,Helena I. S. Nogueira +4 more
TL;DR: In this article, a series of organic-inorganic hybrid materials composed by lanthanopolyoxotungstates and 3-hydroxypicolinic acid were prepared using different lanthanide ions.
Journal ArticleDOI
Coordination modes of 2-mercaptonicotinic acid: synthesis and crystal structures of palladium(II), platinum(II), rhenium(III) and molybdenum(VI) complexes
TL;DR: In this article, the crystal structures of compounds with 2-mercaptonicotinic acid (HnicSH) were determined by X-ray diffraction, and the properties of these compounds were analyzed in infrared and 13C-{1H} NMR spectroscopy.
