Polymer composite pipes are an appealing option as a substitute for conventional steel pipes, particularly due to their inherent corrosion resistance. However, the composite pipes currently used do not allow non-destructive evaluation (NDE) using ins

In this work, reduced Titania (TiO2−x) was obtained by laser ablation of commercial rutile TiO2 powder dispersed in N,N-dimethyl formamide (DMF) using a pulsed Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) laser (532 nm, 10 ns, 10 Hz). It was o

In this work, we initially describe the preparation of magnetic and fluorescent nanocomposites (MF NCs) based on polystyrene/tetraphenylporphyrin/maghemite (PS/TPP/γ-Fe 2 O 3 ). After carrying a series of exploratory experiments, we have found that
