AB - A series of PF-co-doped titanium dioxide (PF-TiO2) samples with various PF contents were synthesized hydrothermally at 250 °C and systematically investigated by means of X-ray diffraction, X-ray photoelectron spectroscopy and electron microscopy. For the PF-co-doping of TiO2, hexafluorophosphoric acid (HPF6) was used. Increasing HPF6 concentration did not decrease the crystallinity of the synthesized samples, but the dopant concentration strongly influenced the size and morphology of the PF-TiO2 nanoparticles. The undoped TiO2 consisted of polymorphic and polydisperse nanoparticles, whereas smaller, predominantly spherical particles were observed for the PF-TiO2 samples. Diffuse reflectance UV-vis spectroscopy revealed that PF-TiO2 exhibited a slightly higher band gap energy than that of undoped TiO2. Despite this blue-shift in absorption edge, the photocatalytic activity of PF-TiO2 was higher than that of undoped TiO2 even under visible light irradiation. The effects of the dopant concentration on the structure and photocatalytic activity are discussed in detail.

AB - The impact of UV irradiation was studied on photosynthesis, photosystem II photochemical yields and antioxidant responses using green-house grown grapevine (Vitis vinifera L. cv. Chardonnay) leaves. Supplemental UV irradiation (280-400 nm) was centred in the UV-B region, and corresponded to 8.95 kJ m(2) d(1) global (280-400 nm) or 8.04 kJ m(2) d(1) UV-B (280-315 nm) biologically effective dose. UV irradiation was applied daily and its effects were evaluated after 4-days. Younger (1-3 weeks-old) leaves (YL) and older (4-6 weeks-old) leaves (OL) were affected differently, UV irradiation decreased their photochemical yields to 78% and 56%, respectively. Unlike OL, YL responded by an increase in UV-B absorbing pigment, anthocyanin and total phenolics contents. UV irradiation increased total antioxidant capacities in YL but not in OL. YL were also different in their ability to increase specific hydroxyl radical and singlet oxygen neutralizing capacities in response to the supplemental UV irradiation, which is reported here for the first time. Our results suggest that the ability of maintaining photosynthesis under supplemental UV is not necessarily determined by base levels of antioxidants but rather by their inducibilities in response to the irradiation and emphasise the importance of comparing leaves of the same age in UV studies. Correlations between various antioxidant capacities, pigment contents and photosynthesis parameters were also examined. However, no single element of the defence system can be picked up as decisive factor of sensitivity to UV.
