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 6 is now online and is a themed issue in honour of Kurt Schaffner on the occasion of his 80^th 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.

PPS 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 12^th April!

Welcome to the first issue of 2012 a themed issue on the biology of UVA! This issue dedicated to UVA contains several in-depth perspectives and original articles in the field highlighting key advances and provides an interesting and comprehensive journey through the UVA field, even those for whom this particular area is less familiar. You can read an introduction to this issue in Evelyn Sage and Rex Tyrrell’s editorial. 

This issue is not only a themed issue, it also contains the 2011 progress report (an update on the full quadrennial report published in 2011 issue 2) from the United Nations Environment Programme, Environmental Effects Assessment Panel on the environmental effects of ozone depletion and its interactions with climate change.

Issue 5 of Photochemical and Photobiological Sciences has now been published online and is a themed issue on Drug delivery technologies and immunological aspects of photodynamic therapy.

The guest editors Kristian Berg (Oslo University Hospital), Jakub Golab (Medical University of Warsaw), Mladen Korbelik (British Columbia Cancer Agency) and David Russell (University of East Anglia), introduce the topic in their editorial which you can read here.

The cover features an article from Gang Zheng and co-workers in Canada and China entitled ‘Cytosolic delivery of LDL nanoparticle cargo using photochemical internalization’.  In this study endolysosmal disruption using PCI was attempted on surface-loaded, protein-loaded and core-loaded cargo incorporated into LDL nanoparticles.
