Ceria has been broadly employed in many technological applications. However, because of geo-strategic concerns, reducing the lanthanide loadings in heterogeneous catalysts while maintaining their good properties has become a main goal in many recent studies. In this work, ceria has been dispersed over two different silica nanoparticle supports, with different sizes and porosity, producing samples with different ceria crystal size and distribution. The influence of these parameters on the redox behaviour of the resulting samples has been investigated, finding a correlation between ceria distribution and both the reducibility and the resistance to deactivation of the systems. Samples obtained from porous silica, consisting of small ceria nanocrystals uniformly distributed along the pore structure of silica, exhibited better reducibility, whereas samples prepared from non-porous silica, presenting a core-shell like structure, had a better resistance against thermal deactivation.

This paper discusses the challenges involved in implementing a new method of AD in Barcelona's Gran Teatre del Liceu through a case study: Giordano's Andrea Chénier. It first describes the main features of opera AD and looks at some of the approaches taken in the UK and Catalonia. Then, it explains a new AD approach proposed by researchers from the Universitat Autònoma de Barcelona. Finally, a general overview of the opera Andrea Chénier is offered discussing the most important challenges and restrictions posed by the genre and explaining how the AD script was drafted and delivered.

Introduction: Stigma towards mental illness affects both the general population and health professionals, leading to poorer care. Objectives: The aim of our study is to assess medical students' attitudes and the possibility to make a change through educational interventions. Methods: 54 fifth-year medical students (41 women) completed a Likert-type attitude assessment scale towards mental illness in future health professionals. They watched videos from #Di_Capacitados, an initiative dedicated to fight stigma, and it was evaluated if they had modified their opinion. In addition to descriptive statistics, Student's t-test was used to compare means. Data analysis was performed with SPPS 25.0. Results: The average score on the attitude scale was 50.07 (SD 12.03), with 14.8% below 40 and 29.6% in the 4th quartile. It was easier to accept the academic or labor integration of the mentally ill, but more difficulties in dealing directly with them were found. After the display of the videos, the overall perception about the disorder and about social and job possibilities improved (in 66.7%, 74.1% and 75.9% of participants, respectively). Conclusions: There was a more negative attitude toward patients with mental illness than the one reflected in the literature, underestimating their ability to perform well socially and at work and reflecting a fearful attitude. Even so, it was better than the one shown by studies in the general population. The perception improvement achieved through audiovisual material showing the reality of these patients agrees with the available bibliography. Academic training seems insufficient to combat stigma and it is necessary to resort to complementary measures. [ABSTRACT FROM AUTHOR]
