The irradiation of ∼0.9-μm-thick hydrogenated amorphous carbon (a-C:H) layers deposited on silicon substrates with single femtosecond (fs) laser pulses (35 fs pulse duration, 790 nm centre wavelength) in air is studied experimentally. Irradiation

Polymorphous silicon thin films were obtained by plasma enhanced chemical vapor deposition using dichlorosilane as silicon precursor. The RF power and the dichlorosilane to hydrogen flow rate ratio were varied to obtain different crystalline fraction

Because of its semiconductor properties, sol-gel zirconia can be used as a photocatalyst. When zirconia is doped with transition metals, its electronic properties are modified. In this work, sol-gel Mn/ZrO2 and ZrO2 materials were tested for photocat

Samples of amorphous sol-gel titania were prepared at 50%wt with tungstophosphoric or molybdophosphoric acid. The resulting gels were dried and annealed at 100, 150 and 200°C and studied by FT-IR, UV-Vis, EPR, TGA and Raman spectroscopy. By FT-IR th

The effect of the incorporation of CeO2 in ZrO2–SO42− was studied. Materials were synthesized by the sol–gel method with varying CeO2 content (10, 20 and 30%). Sample sulfation took place in situ, maintaining the amount of sulfate at 20 wt.% us

Catalysts based in titania mixed with tungstophosphoric acid (TPA), H3PW12O40, in various proportions (1, 15, 25 and 50 wt%) were obtained by the sol–gel method. The gels were prepared by hydrolysis and gellation of titanium n-butoxide with a TPA s

The evolution of the thermal effusivity as a function of time of aqueous emulsions made by sol-gel synthesis of agar encapsulated in a SiO 2 matrix is monitored during dehydration. Measurements of thermal effusivity were performed by the photoacousti
