Alkaline extraction of phenolic compounds from Eucalyptus leaves: influence on ...
Afonso, Tiago Barros; Bonifácio-Lopes, Teresa; Costa, Eduardo; Macedo, Tiago; Moreira, Joana; Oliveira, Juliana; Pintado, ManuelaBackground: The valorization of agro-industrial by-products is a strategic approach to reducing biomass waste while advancing circular bioeconomy practices. Eucalyptus leaves, an abundant residue from the forestry and pulp industries, are particularly rich in phenolic compounds with well- known antioxidant and antimicrobial activities. These bioactivities highlight the potential of eucalyptus extracts for susta...

The influence of humanization in creating authentic brands
Oliveira, JulianaHumanization plays a vital role in building authentic brands, directly influencing the emotional relationship between organizations and consumers. In this context, it is very important to explore the influence of this approach on brand differentiation and success, as well as issues relating to the DNA of authentic brands, the importance of integrity and consistency in communicating companies' values and purpose...
Be@t: sustainable chemical processes for developing regenerative materials and ...
Afonso, Tiago B.; Bonifácio-Lopes, Teresa; Costa, Eduardo M.; Costa, Ana Filipa; Oliveira, Juliana; Pintado, ManuelaIntroduction: The reuse and valorization of waste and by-products generated by other industrial sectors in the textile sector currently represents a strategy of 'sustainable waste minimization,' leading to the achievement of economic development and environmental sustainability goals. In recent years, waste and by-products from industrial processing, e.g., agro-industry, agroforestry, marine, canning, mining, l...

Aguiar, Tatiana Quinta; Oliveira, Juliana; Barros, Ana Rita; Bouça, Verónica; Ramada, David; Freitas, Ana Isabel; Domingues, LucíliaThe present disclosure relates to a labelled article comprising a substrate selected from a list consisting of at least one of the following substrates: paper, cork, leather, yarns, threads, textiles, fabrics, a particle, or combinations thereof; a reversibly switchable fluorescent peptide; and a binder peptide, preferably more than one binder, wherein the binder binds the fluorescent peptide to the substrate, ...
Sustainable identity through switchable fluorescence: smart textiles with rever...
Barros, Ana; Ramada, David; Bouça, Verónica; Oliveira, Juliana; Freitas, Ana Isabel; Domingues, Lucília; Aguiar, Tatiana Quinta[Excerpt] Colour-changing materials with con - trollable properties obtained by low cost and biotechnological means are highly desirable for smart innovative products and applications such as anti-counterfeiting and security printing. Protein-based nanotechno - logy is an ever-growing research field due to the versatility and adap - tability of these biomolecule building blocks and the innovative functiona - li...
Multi-Agent Interaction to Assist Visually-Impaired and Elderly People
Oliveira, Juliana; Engelman, Debora; Kniest, Davi; Vieira, Renata; Bordini, RafaelA voice-controlled smart home system based on conversational agents can address the specific needs of older people, proactively providing support, compensating for cognitive decline, and coping with solitude, among other features. In particular, Multi-Agent Systems (MAS) platforms provide considerable support for complex adaptive systems that are naturally distributed and situated in dynamic environments, such ...
Preliminary Tests with Screen-Printed Piezoresistive Pressure Sensors on PET an...
Martins, Pedro; Silva, Carolina; Oliveira, Juliana; Marques, Maria ArcelinaThe search for more practical and economically advantageous solutions to produce flexible and printable pressure sensors, is giving rise to new approaches with promising results. The production of conductive and piezoresistive inks for application on flexible and stretchable substrates is a sign of this evolution. In this paper, we propose to analyze the results of some calibration tests, performed with pressur...
Innovative eco-sustainable photocontrolable and reversibly photoswitchable fluo...
Oliveira, Juliana; Bouça, Verónica; Barros, Ana; Ramada, David; Freitas, Ana Isabel; Domingues, Lucília; Aguiar, Tatiana QuintaColour-changing materials with controllable properties are highly desirable for technical, smart innovative products. Current developments commonly incorporate photo/thermochromic inks based on molecules obtained by non-sustainable petroleum based sources that do not allow controlled light-driven switching between colors. To overcome these limitations, our project explores the development of new eco-sustainable...

Bouça, Verónica; Oliveira, Juliana; Barros, Ana; Ramada, David; Coelho, Lorena; Freitas, Ana Isabel; Romão, João; Domingues, LucíliaColor-changing materials with controllable photoswitching properties are highly desirable for technical and smart textile products. In the quest for innovative light-responsive textiles, many efforts have been made to develop materials that can be easily incorporated into fibers and/or fabrics by conventional dyeing, printing or coating processes. Current developments commonly incorporate photochromic inks that...
