Photochemical & Photobiological Sciences issue 7 is now available online

Issue 7 of Photochemical & Photochemical Sciences is a themed issue on ‘Blue-light photoreceptors’ and is now available to read online.

The front cover this month features work by Aba Losi and co-workers from Parma, Italy. Their article takes as its starting point the increasing evidence that prokaryotic organisms can sense and react to light stimuli via a variety of photosensory receptors and signal transduction pathways. The authors present a comprehensive scenario of the existence of bilin-GAF, LOV and BLUF proteins in the prokaryotic world, and inspect possible phylogenetic pathways. They also define novel criteria for identifying gene (and protein) sequences based on experimentally assessed photochemical events.

Read the article in full – it’s free to access for the next six weeks:
Distance-tree analysis, distribution and co-presence of bilin- and flavin-binding prokaryotic photoreceptors for visible light
Carmen Mandalari, Aba Losi and Wolfgang Gärtner  
Photochem. Photobiol. Sci., 2013, 12, 1144-1157, DOI: 10.1039/C3PP25404F

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

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.

PPS issue 4, 2013, front coverThe 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.

Themed issue dedicated to Kurt Schaffner now online

Issue 6 coverPPS issue 6 is now online and is a themed issue in honour of Kurt Schaffner on the occasion of his 80th birthday.  You can read the introduction to this issue by Editors Silvia E. Braslavsky, Santi Nonell and Frans De Schryver here.  Read the full themed issue online here.

The front cover features work form Tatsuo Arai and co-workers from the Graduate School of Pure and Applied Sciences, University of Tsukuba, Japan.  Their paper investigates photoisomerization and energy transfer in naphthalene-terminated stilbene dentrimers.  They demonstrate photoisomerazion via highly efficient energy transfer from the dendron group to the core stilbene and that intramolecular energy transfer efficiency was controlled by trans-cis photoisomerization.

Themed issue on photoremovable protecting groups is now online!

PPS Issue 3 CoverPPS Issue 3 is now online and is a themed issue on photoremovable protecting groups: development and applications, see the full issue here.  This themed issue presents research papers and perspectives on applications of photoremovable protecting groups that provide spatial and temporal control over the release of various chemicals and bioagents. Read Guest Editor Jacob Wirz’s Editorial which introduces the topic here.

The front cover represents an article by Andrei G. Kutateladze and co-workers from the University of Denver in the USA.  In their study externally sensitized fragmentation in dithiane PPG-protected carbonyls is adopted for detection and amplification of binding events, which trigger massive self-amplified release of benzophenone from its masked state, simultaneously quenching the fluorescence.  Read the full article for free here until 12th April!

Tanning salons and skin cancer

Tanning salons and skin cancerIn a recently published perspective on the use of sunbeds Jean-François Doré and Marie-Christine Chignol discuss prevalence of their use and examine the evidence suggesting that use of indoor tanning increases the risk of skin Cancer.  The authors conclude that the use of sunbeds should be strongly discouraged and banned under the age of 18. To find out more, read the full article for free until September 16th!

Themed issue: Solar chemistry & photocatalysis – environmental applications

Issue 3 of PPS has been published online. This issue is a collection of papers presented at the 6th European meeting on Solar Chemistry and Photocatalysis: Environmental Applications (SPEA6), which was held in Prague, Czech Republic, in June 2010, and was organized by Josef Krysa and Jaromýr Jirkovsky. The issue is guest edited by Josef Krysa and Sixto Malato.

The cover of the issue features a paper by Rudolf Słota and coworkers on photocatalysis by TiO2 composites with phthalocyanines and porphyrins. They show the importance of matching the sensitizer to the nature of the TiO2 (micro- or nanocrystalline).

Also in the issue, Maria Antoniadou and Panagiotis Lianos have made a photoactivated fuel cell that uses organic waste to produce electricity. They tested the system on a number of polyols, but suggest that almost any organic substance can be used. The cell uses UVA light, and can run on the UV component of sunlight.

These papers and the rest of the issue can be read online now.
