PPS issue 5 now available online!

25 Apr 2013

By Emma Eley, Development Editor.

Issue 5 of Photochemical & Photobiological Sciences is now available to read online.

The front cover this month features work by Giuseppe Calogero, Fernando Pina and co-workers from from Messina, Italy, and Caparica, Portugal. In their paper, flavylium salt dyes were employed for the first time as sensitizers for dye-sensitized solar cells (DSSCs) and photoelectrochemical measurements showed that they are very promising compounds for such applications. These synthetic analogues of anthocyanins could present a new type of “biomimetic” environmentally friendly sensitizers.

PPS issue 4 is now published online – Solar Chemistry & Photocatalysis: Environmental Applications

27 Mar 2013

By Mary Badcock, Deputy Editor.

The latest issue of PPS is now available to read online! This month’s issue is a themed issue of contributions from the 7th European Meeting on Solar Chemistry & Photocatalysis: Environmental Applications (SPEA 7), held in Porto from 17th to 20th June 2012. Read the Editorial by Guest Editors Joaquim Faria and Sixto Malato here.

The front cover highlights work by Roland Marschall and co-workers from Ruhr-University Bochum, Germany. They developed barium tantalate composites which showed enhanced photocatalytic hydrogen generation. After preparing (111)-layered Ba₅Ta₄O₁₅photocatalysts via a solid-state reaction route and a citrate synthesis route, X-ray powder diffraction and absorption spectroscopy determined the presence of a second phase – Ba₃Ta₅O₁₅. The Ba₅Ta₄O₁₅/Ba₃Ta₅O₁₅ composites demonstrated up to 160% higher hydrogen evolution rates than for pure Ba₅Ta₄O₁₅. In addition, only very small amounts of Rh co-catalyst (0.025%) were needed to achieve these results.

PPS issue 3 now available online!

20 Feb 2013

By Mary Badcock, Deputy Editor.

Issue 3 of Photochemical & Photobiological Sciences is now available to read online.

Front cover of PPS issue 3, 2013 The front cover this month feature work by Halan Prakash and colleagues from the Birla Institute of Technology and Science, India, who looked at the ability of persulphate to cause degradation of organic contaminants and also its effect on bacteria in aqueous media. The team used methyl orange, a model azo dye, and Gram positive and negative bacteria. Visible light activation of persulphate was achieved using ruthenium(II) polypyridyl complexes, which produced sulphate radicals and led to significant degradation of methyl orange as well as complete inactivation of bacteria.

Photodegradation of methyl orange and photoinactivation of bacteria by visible light activation of persulphate using a tris(2,2′-bipyridyl)ruthenium(II) complex, Gokulakrishnan Subramanian, Priyadarshini Parakh and Halan Prakash, Photochem. Photobiol. Sci., 2013, 12, 456-466

Highly fluorescent peptide nanoribbon impregnated with Sn-porphyrin as a potent DNA sensor

07 Feb 2013

By Mary Badcock, Deputy Editor.

Peptide nanostructures have recently been identified as an important bio-functional nanostructure. Researchers have demonstrated that modification of these peptide nanostructures can greatly expand their biological applications.

In this work, Minjoong Yoon and colleagues from Chungnam National University, Republic of Korea, have prepared peptide nanoribbons (PNRs) impregnated with a Sn-porphyrin via solvothermal self-assembly. The resulting nanoribbons are highly fluorescent and thermo-stable. However, the fluorescence intensity and life-time were selectively affected upon interaction with the nucleotide base sequences of DNA, thus implying that these Sn-porphyrin-PNRs could be useful as a biocompatible DNA sensor.
