  • Are Lisbon attractions smart looking for tourist perceptions?
    Publication . Rosário, João Ferreira do; Gustavo, Nuno; Batista, Manuel José Marques; Calisto, Maria de Lurdes; Machado, Ana Teresa
    STRUCTURED ABSTRACT Purpose – This study intends to demonstrate tourists’ perception about Lisbon’s tourist attractions as smart. Theoretical framework – The technology Era is characterized by an increasingly global and heterogeneous tourism demand, who is more and more technology-oriented (Huang, Goo, Nam & Yoo, 2017; Xiang, 2018). Simultaneously, there is a growing implementation of new and intelligent functionalities, shifting the way tourism experiences are consumed, by emphasizing the interactive dimension on tourists’ experience (Li, Hu, Huang & Duan, 2017). This scenario underlies an opportunity for tourism innovation based on technological solutions. Design/methodology/approach – Questionnaires will be administrated to tourists visiting Lisbon. From a list of 28 items, mainly based on Wang, Li, Zhen and Zhang’s study (2016), it is intended to measure tourists’ preferences of smart tourism attractions. Participants will select the smartest attraction, evaluating its performance regarding the 28 items. Findings – It is intended to perform a factor analysis that will allow to extract the factors related with tourists’ preferences of smart tourism attractions. These results will sustain further analysis on comparing the importance attributed with the performance perceived. Research, Practical & Social implications – By demonstrating tourists’ preferences on smart tourist attractions and the gap perceived regarding Lisbon’s smart tourist attractions, this study allows for those who manage these attractions to meet demand’s expectations. Originality/value – Identifying Lisbon’s strengths and weaknesses as a smart tourism destination and provide future directions.

  • 1D Copper(II)-aroylhydrazone coordination polymers: magnetic properties and microwave assisted oxidation of a secondary alcohol
    Publication . Sutradhar, Manas; Alegria, Elisabete; Roy Barman, Tannistha; Guedes Da Silva, M. Fátima C.; Liu, Cai-Ming; Pombeiro, Armando
    The 1D Cu(II) coordination polymers [Cu-3(L-1)(NO3)(4)(H2O)(2)](n) (1) and [Cu-2(H2L2)(NO3)(H2O)(2)](n)(NO3)(n) (2) have been synthesized using the aroylhyrazone Schiff bases N'(1),N'(2)-bis(pyridin-2-ylmethylene)oxalohydrazide (H2L1) and N'(1),N'(3)-bis(2-hydroxybenzylidene)malonohydrazide (H4L2), respectively. They have been characterized by elemental analysis, infrared (IR) spectroscopy, UV-Vis spectroscopy, electrospray ionization mass spectrometry (ESI-MS), single crystal X-ray diffraction and variable temperature magnetic susceptibility measurements (for 2). The ligand (L-1)(2-) coordinates in the iminol form in 1, whereas the amide coordination is observed for (H2L2)(2-) in 2. Either the ligand bridge or the nitrate bridge in 2 mediates weak antiferromagnetic coupling. The catalytic performance of 1 and 2 has been investigated toward the solvent-free microwave-assisted oxidation of a secondary alcohol (1-phenylethanol used as model substrate). At 120 degrees C and in the presence of the nitroxyl radical 2,2,6,6-tetramethylpiperydil-1-oxyl (TEMPO), the complete conversion of 1-phenylethanol into acetophenone occurs with TOFs up to 1,200 h(-1).
