Journal ArticleDOI
Coordination modes of 2-hydroxynicotinic acid in second- and third-row transition metal complexes
TL;DR: In this paper, the new Pd(II), Pt(II, Re(V), Mo(VI), and W(VI) complexes of 2-hydroxynicotinic acid (H2nicO) have been prepared.
Journal ArticleDOI
Carbon-based heterogeneous photocatalysts for water cleaning technologies: a review
TL;DR: In this article, a review of the application of carbon-based nanostructures for heterogeneous photocatalysis applied to water purification is presented, where the photocatalytic efficiency of hybrid nanocomposite materials is attributed to improved light harvesting and reduced recombination of photogenerated charge carriers.
Journal ArticleDOI
The associations of SES, obesity, sport activity, and perceived neighborhood environments: is there a model of environmental injustice penalizing Portuguese children?
Helena I. S. Nogueira,Augusta Gama,Augusta Gama,Isabel Mourão,Vitor Rosado Marques,Maria Ferrão,Cristina Padez +6 more
TL;DR: This study analyses the associations between children's obesity, sports activity (SA), and perceived environmental characteristics with the children's SES.
Journal ArticleDOI
Synthesis, characterisation and magnetic properties of cobalt (II) complexes with 3-hydroxypicolinic acid (HpicOH): [Co(picOH)2(H2O)2] and mer-[N(CH3)4][Co(picOH)3].H2O
Penka I. Girginova,Filipe A. Almeida Paz,Filipe A. Almeida Paz,Helena I. S. Nogueira,Nuno Silva,Vitor S. Amaral,Jacek Klinowski,Tito Trindade +7 more
TL;DR: In this paper, the properties of these two compounds were further investigated by measuring their magnetic behavior, and they were synthesized and characterised using single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy, and thermoanalytical measurements.
Journal ArticleDOI
FT‐IR, FT‐Raman, SERS spectra and computational calculations of 4‐ethyl‐N‐(2′‐hydroxy‐5′‐nitrophenyl)benzamide
C. Yohannan Panicker,Hema Tresa Varghese,L. Ushakumari,Tugba Ertan,Ilkay Yildiz,Carlos M. Granadeiro,Helena I. S. Nogueira,Y. Shyma Mary +7 more
TL;DR: In this article, the Fourier transform infrared (FT-IR) and FT-Raman spectra of 4-ethyl-N-(2′-hydroxy-5′-nitrophenyl)benzamide were recorded and analyzed.
