Num contexto histórico, a frequência de gestações trigemelares atingiu o seu auge nos finais do século XX e diminuiu significativamente a partir de então, registando-se atualmente uma frequência de 0,2 por 1000 grávidas. Atualmente, os grandes fatores etiológicos que estão na or…
A fabricação digital se tornou uma realidade para a produção em diversos setores da indústria nos últimos anos. Com seu uso desenvolvido e consolidado em alguns setores como a medicina, a arquitetura e a robótica, ela ainda é pouco explorada na moda apresentando um grande potenc…
Light scattering from particles in the nanometric and micrometric size range is relevant in several research fields, such as aerosol science and nanotechnology. In many applications, the description of the optical properties of non-spherical, inhomogeneous particles is still ina…
This thesis builds on recent innovations in multi-phase emulsion droplet design to demonstrate that emulsion morphologies enable a useful variety of dynamic optical phenomena. Despite the highly dynamic nature of fluid morphologies and their utility for stimuli-responsive, dynam…
