Strategic visuality: Exploring the role of imagery in brand visual language - A...

Gastal, Manuela; Oliveira, Fernando; Raposo, Daniel

Although the concept of image has been examined across multiple disci-plinary fields, there remains a notable gap in scholarly literature regarding the role of imagery in constructing a brand’s symbolic repertoire, meaning, and communicative strategies. This study aims to investigate the relationship between brand imagery and brand personality, with the objective of proposing parameters that inform the devel-op...


Promoting the role of parents in preventing child sexual abuse: scoping review ...

Terra, Penélope Morais; Fernandes, Rita; Alves, José; Oliveira, Fernando; Sousa, Paula; Torres, Cânia

Introduction: Child sexual abuse includes any sexual act involving children, with or without physical contact. Understanding its complexity and promoting anticipatory parental competencies are essential for guiding effective preventive interventions. Objectives: To map clinically relevant scientific evidence on nursing interventions aimed at the parental role in preventing child sexual abuse. Methodology: A Sco...


Comparison of the corrosion of ferritic and austenitic stainless steel (AISI 43...

Gil, Mafalda; Pedrosa, Fátima; Paiva Luís, Teresa; Figueira Vasques, Isabel; Oliveira, Fernando; Cunha Diamantino, Teresa

ABSTRACT: This study focuses on the corrosion rates and mechanisms of two stainless steels, austenitic AISI 316L and ferritic AISI 430, in contact with a eutectic mixture of LiNaK carbonates in long-term tests at 650 degrees C. The selection of these two stainless steels was based on their differences, both in their intrinsic characteristics and in the cost associated with each one. The research also underscore...

Thermochemical performance of ceria coated-macroporous 3D-printed black zirconi...

Oliveira, Fernando; Barreiros, Maria Alexandra; Sardinha, Manuel; Leite, Marco; Fernandes, Jorge; Abanades, Stéphane

ABSTRACT: The use of macroporous structured ceria for the solar thermochemical splitting of CO2 and H2O to produce clean fuels through two-step redox cycles was investigated. The research aimed to assess the reactivity of 3D-printed black zirconia gyroid structures coated with a microporous layer of pure CeO2 for producing CO and H2. Such porous designs are intended to increase both the absorption of solar radi...

Mechanical Performance of Ceria-Coated 3D-Printed Black Zirconia Cellular Struc...

Oliveira, Fernando; Sardinha, Manuel; Justino Netto, Joaquim Manoel; Leite, Marco; Farinha, Miguel; Barreiros, Maria Alexandra; Abanades, Stéphane

ABSTRACT: Solar fuels production requires developing redox active materials with porous structures able to withstand thermochemical cycles with enhanced thermal stability under concentrated solar irradiation conditions. The mechanical performance of 3D-printed, macroporous black zirconia gyroid structures, coated with redox-active ceria, was assessed for their suitability in solar thermochemical cycles for CO2 ...

Dielectric UV filters for protection of fire-resistant glass based on intumesce...

Silva, Ricardo Magno Lopes; Hashim, Hurraira; Roy, Deepto; Oliveira Fernandes, Carolina; Oliveira, Kevin; Leitão Pinheiro, Xavier Alexandre

ABSTRACT: Structures such as OLEDs, perovskite solar cells, intumescent glasses, and other components in modern devices and buildings contain materials suscep-tible to degradation when exposed to UV radiation, requiring protection to with-stand outdoor environmental conditions. In this work, multilayer coating config-ured as a Bragg Reflector on glass is employed as spectral filtering to protect the intumescent...
