    “…Particularly, geopolymer matrices obtained from different solid precursors (fly ash and metakaolin), composite systems (siloxane-hybrid, foamed hybrid), and curing temperatures (room temperature and 60 °C) were investigated for the same photocatalyst content (i.e., 3% TiO(2) by weight of paste). The geopolymer matrices were previously designed for different applications, ranging from insulating (foam) to structural materials. …”

    “…This work shows the influence of algae age (at the time of the exposure) and the initial algae population on the response of green algae Raphidocelis subcapitata to titanium dioxide nanoparticles (TiO(2) NPs). The different algae age was obtained by changes in flow rate of continually stirred tank reactors prior to NP exposure. …”

    “…Concomitant with the anodization time, the NT length, fluorine content, and capacitance of the space charge region increased, affecting the opto-electronic properties (bandgap, bathochromic shift, band-edge position) and surface hydrophilicity of TiO(2) NTs. These properties are at the origin of the photocatalytic activity (PCA), as proved with the photooxidation of methylene blue.…”
