Improvement of the Mechanical Properties of Silica Aerogels for Thermal Insulat...
Ghica, Mariana E.; Mandinga, Jandira G. S.; Linhares, Teresa; Almeida, Cláudio M. R.; Durães, LuisaReinforcement of silica aerogels, remarkable lightweight mesoporous materials with outstanding insulation performance, is still a challenging research topic. Among the strategies used to overcome their brittleness, one of the most effective is the manufacturing of aerogel composites with embedded fibres. In this work, the incorporation of nanofibres together with microfibres in a tetraethoxysilane-vinyltrimetho...
A Comparative Thermoacoustic Insulation Study of Silica Aerogels Reinforced wit...
Linhares, Teresa; Carneiro, Vitor H.; Pessoa de Amorim, Maria T; Durães, LuisaSilica aerogels are highly porous materials with exceptional thermal insulation performance. They become even more attractive if combined thermal and acoustic insulation is achieved. Silica aerogel composites reinforced with fibres are an ingenious way to surpass the fragility stemmed from the aerogel's intrinsic porosity, and textile fibres are good sound absorption materials. Reclaimed fibres are a relatively...
Biological Thermal Performance of Organic and Inorganic Aerogels as Patches for...
Ferreira-Gonçalves, Tânia; Iglesias-Mejuto, Ana; Linhares, Teresa; Coelho, João M. P.; Vieira, Pedro; Faísca, Pedro; Catarino, José; Ferreira, DavidAerogels are materials with unique properties, among which are low density and thermal conductivity. They are also known for their exquisite biocompatibility and biodegradability. All these features make them attractive for biomedical applications, such as their potential use in photothermal therapy (PTT). This technique is, yet, still associated with undesirable effects on surrounding tissues which emphasizes ...
Avaliação de técnicas de oxidação avançada no tratamento de água para consumo h...
Duarte, António A. L. Sampaio; Silva, Sílvia C. F.; Linhares, Teresa; Amorim, M. T. Pessoa deFace ao aparecimento de contaminantes emergentes e altos custos associados às novas tecnologias de remoção destes contaminantes e matéria orgânica natural (MON), é necessário e essencial o desenvolvimento de tecnologias de tratamento igualmente eficientes, ambientalmente mais sustentáveis e de baixo custo. Deste modo, o presente artigo tem como principal objetivo o desenvolvimento e avaliação da eficiência de t...
