Functionalization of woven fabrics for antimicrobial capability using microcapsules with essential oils

[Excerpt] The functionalization of textiles covers multiple objectives, such as the allocation of perfumes, antimicrobials, some drugs, phase change materials. Among these goals, the antimicrobial capability ensures that microorganisms do not thrive on textiles (Fig. 1), allowing users to use these products safer in different scenarios. This research evaluates the antimicrobial capacity of cotton fabrics through the application of microcapsules containing essential oils.The authors are grateful to the Agência Nacional de Inovação for the funding of the Project 4NoPressure - POCI-01-0247- FEDER-039869 and ARCHKNIT POCI-01-0247-FEDER-03973, co-funded by the European Regional Development Fund (ERDF), through the Operational Programme for Competitiveness and Internationalisation (COMPETE 2020), under the PORTUGAL 2020 Partnership Agreement

Development of a plasma activated multifunctional polyester fabric using zinc oxide nanoparticles and citronella oil microcapsules

There is a high demand for the development of textiles possessing multifunctional properties for outdoor, protective and health care applications. The coating of polyester (PES) textiles with metal nanoparticles and essential oils may act in a synergistic mode to obtain materials with improved antimicrobial and UV-protection properties. However, the lack of functional groups onto PES structure makes the adhesion of particles a difficult task. In this work, PES fabric was activated by dielectric barrier discharge (DBD) plasma treatment, and functionalized with zinc oxide nanoparticles (ZnO NPs) and poly (methyl methacrylate) (PMMA)-citronella microcapsules by dip-coating

Characterization of materials used in car multimedia products and study the influence of the cleaning process on test boards

Dissertação de mestrado em Técnicas de Caracterização e Análise QuímicaIn recent years, technological development requires more complex PCB and PCBA production processes. Miniaturization is one of the greatest challenges in today's electronics industry, requiring a higher density of electronic components in the smallest area possible. However, changes in PCB layout rules, reduced size of electronic components and increased functionality may jeopardize product reliability. Therefore, materials with several functions are applied to PCBs, such as materials that allow the dissipation of the heat generated by the components (Gap Filler) and that increase the thermomechanical resistance of the soldering joints (Underfill). In addition to the application of interconnection materials, non-standard CM processes are also used, such as the Defluxing process. Accordingly, this dissertation was based on two distinct objectives: the characterization of Gap Filler (GF) and Underfill (UF) materials and the study of the Defluxing process influence on test boards. The characterization of the materials was performed by the following analytical methods: molecular structure was investigated by ATR-FTIR, chemical composition by IC and HPLC-MS and morphology by SEM-EDS and XRD. The thermal properties were evaluated by STA and the rheological properties of the materials were also determined. Finally, GC-MS analysis was used to identify released volatiles. In the second part of this project, the IPC-B-52 board was used as a test vehicle to study the influence of the Defluxing process. Analysis of ionic and organic residues was performed by ROSE, IC and HPLC-MS. In order to investigate the impact of residues on the reliability of the IPC-B-52 board, SIR tests were also performed. Selected analytical methods allowed the study of UF and GF materials, being its structure and thermomechanical behavior characterized. Properties that may influence the production process and the volatiles released by the materials were also investigated. It was concluded that the Defluxing process has no advantages over a no-clean process.Nos últimos anos, tem se verificado que o desenvolvimento tecnológico requere cada vez processos mais complexos de produção de PCBs e PCBAs. A miniaturização é um dos maiores desafios da indústria eletrónica na atualidade, sendo necessária uma maior densidade de componentes eletrónicos numa menor área possível. Contudo, alterações nas regras de layout dos PCBs, a redução das dimensões dos componentes eletrónicos e o aumento das suas funcionalidades, podem comprometer a fiabilidade dos produtos. Assim sendo, materiais com diversas funções são aplicados nos PCBs, tais como materiais que permitam a dissipação do calor gerado pelos componentes (Gap Filler) e o aumento da resistência termomecânica das juntas de soldadura (Underfill). Além da aplicação de materiais de interconnexão, processos não standard para CM são também utilizados, como por exemplo o processo de Defluxing. Assim, esta dissertação teve como base dois objetivos distintos: a caraterização dos materiais Gap Filler (GF) e Underfill (UF) e o estudo da influência do processo de Defluxing em placas teste. A caraterização dos materiais acima referidos foi realizada através dos seguintes métodos analíticos: a estrutura molecular foi investigada por FTIR-ATR, a composição química por IC e HPLC-MS e a morfologia por SEM-EDS e XRD. As propriedades térmicas foram avaliadas por STA e foram também determinadas as propriedades reológicas dos materiais. Por fim, a análise por GC-MS foi utilizada para a identificação de voláteis libertados. Na segunda parte deste projeto, foi utilizada como veículo teste a placa IPC-B-52, para o estudo da influência do processo de Defluxing. A análise dos resíduos iónicos e orgânicos foi realizada por ROSE, IC e HPLC-MS. De forma a investigar o impacto dos resíduos na fiabilidade da placa IPC B-52, foram também realizados testes SIR. Os métodos analíticos selecionados permitiram o estudo dos materiais GF e o UF, tendo sido caraterizada a sua estrutura e comportamento termomecânico. Propriedades que podem influenciar o processo de produção e os voláteis libertados pelos materiais foram também investigados. Foi demonstrado que o processo de Defluxing não apresenta vantagens em relação a um processo No-Clean

Methodological approaches for monitoring five major food safety hazards affecting food production in the Galicia-Northern Portugal Euroregion

The agri-food industry has historically determined the socioeconomic characteristics of Galicia and Northern Portugal, and it was recently identified as an area for collaboration in the Euroregion. In particular, there is a need for action to help to ensure the provision of safe and healthy foods by taking advantage of key enabling technologies. The goals of the FOODSENS project are aligned with this major objective, specifically with the development of biosensors able to monitor hazards relevant to the safety of food produced in the Euroregion. The present review addresses the state of the art of analytical methodologies and techniques-whether commercially available or in various stages of development-for monitoring food hazards, such as harmful algal blooms, mycotoxins, Listeria monocytogenes, allergens, and polycyclic aromatic hydrocarbons. We discuss the pros and cons of these methodologies and techniques and address lines of research for point-of-care detection. Accordingly, the development of miniaturized automated monitoring strategies is considered a priority in terms of health and economic interest, with a significant impact in several areas, such as food safety, water quality, pollution control, and public health. Finally, we present potential market opportunities that could result from the availability of rapid and reliable commercial methodologies.This project was co-financed by the European Regional Development Fund (ERDF) through the Interreg VA Spain-Portugal (POCTEP) 2014–2020 Program under grant agreement 0591_FOOD SENS_1_E.

Boas práticas ao Serviço do Utente - Centro Hospitalar do Tâmega e Sousa, EPE

O CHTS pretende e ambiciona na literacia em saúde, na vertente do cidadão, que haja mais igualdades em saúde e que, este cidadão perante a necessidade de tomar decisões de forma autónoma (muitas vezes de elevada complexidade), sobre a promoção de saúde, prevenção das doenças ou seu tratamento, esteja informado e com conhecimentos para o fazer. Pretende que o cidadão seja capaz de obter melhor acesso aos cuidados de saúde, usar e usufruir da forma mais adequada e, de forma intencional e consciente, possa obter os maiores benefíciospara a manutenção do seu estado de saúde. A OMS, define Literacia em Saúde como “o grau em que os indivíduos têm a capacidade de obter, processar e entender as informações básicas de saúde para utilizarem os serviços e tomarem decisões adequadas de saúde”, ou seja, a literacia em saúde contempla um conjunto de conhecimentos, atitudes, habilidades e até competências que capacitam a pessoa no acesso, compreensão das informações para que possa avaliar de forma critica a sua relevância no uso responsável desse conhecimento. Foi, neste contexto, que surgiu no CHTS uma nova ótica de leitura e de intervenção das suas equipas multidisciplinares, na consecução de projetos e ações que visam reforçar os níveis de literacia, de forma multidimensional e colaborativa, aproximando-se cada vez mais da centralidade no cidadão, bem como de uma maior eficiência e eficácia dos serviços, qualidade assistencial e satisfação do cidadão e profissional. Deve-se muito à capacidade dos profissionais de saúde, mesmo com diferenças de uns para outros, em identificar as necessidades das pessoas, em estarem disponíveis para promover mudança, a avaliar diariamente o nível de compreensão, capacidades para realizar tarefas prescritas, motivação e nível de mudança comportamental do cidadão, tendo em conta a sua idade e o seu estado de saúde.

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
