Effect of the synthesis parameters on the physicochemical properties of NaY Zeo...
Fernandes, Auguste; Plateau, Christiaan; Lourenço, João P.; Costa, Daniel; Esteves, Laura M.; Ferreira, Maria João; Nogueira, IsabelNaY material belongs to the iconic family of zeolites with a Faujasite structure. These microporous aluminosilicate materials possess exceptional properties, making them essential in various applications, e.g., catalysis, gas sorption/separation, and ion exchange. In particular, NaY zeolite is a good model material for teaching fundamental concepts in crystallography, surface chemistry, and adsorption phenomena...
Adoption of Generative AI in Portuguese Higher Education: An Empirical Study of...
Santos-Pereira, Carla; Durão, Natércia; Ferreira, Maria João; Sobral, Sónia Rolland; Lobo, Carla Azevedo; Moreira, FernandoGenerative artificial intelligence (GenAI) is diffusing rapidly in higher education, yet empirical evidence from Portugal remains limited. We conducted an online questionnaire (n = 77) targeting higher-education faculty and researchers in Portugal and analyzed the data using descriptive statistics and non-parametric tests (Mann–Whitney, Kruskal–Wallis). Participants most frequently reported using QuillBot, foll...

Integrating the is success model in the development of an Intranet project
Magalhães, Tiago; Varajão , João; Ferreira, Maria João; Pinto , Carlos; Rodrigues, Luis SilvaIn recent years, several intranet implementation projects have been developed in organizations. These solutions have proven useful for improving communication and collaboration between departments and other organizational structures. However, intranet implementation projects are not without risks, and their adoption must be adequately managed to reduce deployment errors, resistance to change, and other problems...
Stakeholders' engagement in digital transformation initiatives
Ferreira, Maria João; Seruca, Isabel; Lopes, Filomena CastroDigital transformation (DT) has shifted from a trend to an increasingly accepted reality in the global and organizational scenarios, shaping behaviors, social interactions, economies and operations, as well as driving innovation. While DT, powered by emergent technologies, holds significant potential for businesses, its success hinges on effective stakeholder engagement. By involving stakeholders actively in th...
The role of Project-Based Learning (PBL) to promote the development of student’...
Fernandes, Sandra; Albuquerque, Ana Sílvia; Ferreira, Maria JoãoThis paper analyses the impact of Project-Based Learning (PBL) on the development of lifelong learning skills among first-year students who participated in a PBL approach. The study involved 18 students, enrolled in the first year the Social Education bachelor’s program, at Portucalense University, Porto, Portugal. The project involved three curricular units: Research Methods and Techniques II, Ethics and Educa...
Arabinogalactan proteins: decoding the multifaceted roles in plant reproduction
Silva, Jessy; Moreira, Diana; Ferreira, Maria João; Pereira, Ana Marta; Pereira, Luís Gustavo; Coimbra, SílviaArabinogalactan proteins (AGPs) are highly glycosylated cell wall proteins essential for plant growth and reproduction. AGPs are extensively decorated with arabinogalactan polysaccharides, composed primarily of arabinose and galactose, along with minor sugars such as glucuronic acid, fucose, and rhamnose. Their glycosylation patterns and glycosylphosphatidylinositol anchor enable interactions with receptors, mo...
The collection of the economic kitchens at the Museu de São Roque of Santa Casa...
Amaro, Gonçalo; Simões, João Miguel; Ferreira, Maria JoãoThe end of the 19th century was marked by the creation of social support to face the deterioration of living conditions in urban environments, from the so-called soup kitchens and charity soups, to the economical kitchens, which sold meals at low prices. The Santa Casa da Misericórdia de Lisboa was at the forefront of assisting the needy population of the capital, by providing food in the poorest neighbourhoods...

Oliveira, Catarina Félix de; Sobral, Sónia Rolland; Ferreira, Maria João; Moreira, FernandoToday, higher education institutions are focused on understanding which factors are associated with the failure or success of students to, early on, be able to implement measures that can reduce the low performance of students and even dropout. The retention rate is positively and negatively influenced by factors belonging to several dimensions (personal, environmental, and institutional). We aim to use informa...
