    Bacterial infections and incomplete biomaterial integration are major problems that can lead to the failure of medical implants. However, simultaneously addressing these two issues remains a challenge. Here, we present a ...
  • Photoproduction of hydrogen in microreactors: catalytic coating or slurry configuration? 

    Chausse Calbet, Victor; Llorca Piqué, Jordi (2020-01-01)
    Article
    Restricted access - publisher's policy
    A quartz microreactor containing 28 microchannels of 500 µm width and 105 mm length has been used to photoproduce hydrogen from liquid water-ethanol using an Au/TiO2 photocatalyst and UV light. The photomicroreactor has ...
  • The effect of microcellular structure on the dynamic mechanical thermal properties of high-performance nanocomposite foams made of graphene nanoplatelets-filled polysulfone 

    Antunes, Marcelo de Sousa Pais; Abbasi, Hooman; Velasco Perero, José Ignacio (Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-29)
    Article
    Open Access
    Polysulfone nanocomposite foams containing variable amounts of graphene nanoplatelets (0–10 wt%) were prepared by water vapor-induced phase separation (WVIPS) and supercritical CO2 (scCO2) dissolution. WVIPS foams with two ...
  • Statistics of dislocation avalanches in FCC and BCC metals: dislocation mechanisms and mean swept distances across microsample sizes and temperatures 

    Alcalá Cabrelles, Jorge; Ocenásek, Jan; Varillas Delgado, Javier; El-Awady, Jaafar A.; Wheeler, Jeffrey; Michler, Johann (Nature, 2020-12-01)
    Article
