Themed issue: Solar 新利手机客户端chemistry & photocatalysis – environmental applications

Issue 3of PPS has been published online.This issue is a collection of papers presented at the6th European meeting on Solar 新利手机客户端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.

Thecoverof the issue featuresa paper by Rudolf Słota and coworkerson photocatalysis by TiO2composites 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,玛丽亚Antoniadou Panagiotis Lianoshave 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 issuecan be read onlinenow.

Themed issue: Environmental effects of ozone depletion and its interactions with climate change

cover imageTheFebruary 2011 issuePPShas been published online.This issue contains the 2010 assessment from theEnvironmental Effects Assessment Panelof the theUnited Nations Environment Programme.

The papers in the issue review the latest research on the depletion of the ozone layer and the effects of UV radiation on human health,the environment and materials.

In the 1980s the "ozone hole" was big news and "slip,slop,slap and wrap" and similar campaigns have been heavily promoted in some parts of the world,so it is very interesting reading in the report how effective theMontreal Protocolhas been,with the mid-latitude ozone predicted to reach pre-1980 levels by the middle of this century.

Climate change is,of course,not the same as ozone depletion,but the two atmospheric phenomena can't exist in isolation and the report discusses their interactions.Although the ozone layer is recovering,the report points out that changes in climate (e.g.cloud cover,pollution,other aerosols) also affect the amount of UV-B that reaches the Earth's surface.Because future climate change is less certain,this means that the effects of UV on health and the environment are still difficult to predict.

Full reports from UNEP have been published every four years (the last was in theMarch 2007 issueof PPS),and PPS has also publishedannual progress reports.

As well as the detailed papers,the issue also includes anExecutive summary和一个FAQ.

Read the whole issuenow.

Themed issue: Photo新利手机客户端sciences – a look into the future

The current themed issue gathers the communications presented at the meeting on "Ciamician–Paternò heritage.Photo新利手机客户端sciences: a look into the future",held in Ferrara,Italy,July 16–17,2010.The participants at the meeting discussed their views on the future of photo新利手机客户端chemistry.Those are captured in this themed issue (two more perspectives will appear in future issues of PPS).We would like to thank Angelo Albini,University of Pavias,Italy,who guest edited this issue.

Themed issue: Photosensitive retinal pigments

Read everything about the pigments in the eye!

Issue 11Photochemical & Photobiological 新利手机客户端Sciences,is a themed issue on photosensitive retinal pigments.The issue was guest edited by Professors Rosalie Crouch and Yoshinori Shichida.

In their editorial,the guest editors explain that "Pigments all either use vitamin A aldehyde (retinal) as their chromophore,thus allowing the absorption of light,or contain vitamin A derivatives as the base of their structure.The structure,function and evolution of rhodopsins are discussed in several reviews and papers.

The fate of the retinal chromophore on the absorption of light is covered in another.

Bistable rhodopsins such as melanopsin and parapinopsin are also reviewed.In addition,a method for quantitative measurements of the light-induced body color change in zebrafish larvae is discussed.Several papers address the bis-retinoids of the retina,particularly A2E,which is an important aging topic.The carotenoid binding proteins,which are also likely to be of clinical relevance,are also reviewed. "

We hope that you will find those papers and reviews exciting!

Themed Issue: Photofunctional proteins

Our latest themed issue onPhotofunctional proteins: from understanding to engineering,is nowonline.  The issue was guest edited by Professors Aba Losi,Cristiano Viappiani and Santi Nonell.

It contains various topics such as optogenetics where light-gated proteins originally designed by nature,also known as photoreceptors,are exploited as tools to elegantly photomodulate cell activities.Other topics cover fluorescent proteins and its applications in genetic engineering.Fluorescent proteins have revolutionized the field of molecular biology and in fact this was recognized with the 2008 Nobel Prize awarded to the pioneers in the field Osamu Shimomura,Martin Chalfie and Roger Y.Tsien.

We hope that you will find this themed issue on photofunctional proteins an enjoyable read.

Solar disinfection of wastewater

Fernández-Ibáñez and co-workers showed thatF.equisetichlamydospores in distilled and simulated municipal wastewater effluent were inactivated with 10 mg L−1of H2O2in a 60 L CPC photoreactor. They explained that the use of low concentrations of hydrogen peroxide and CPC systems may be a good alternative for disinfection of resistant microorganisms in water.

Download the full articlehere.This paper is published as part of the themed issue of contributions from the 6th European Meeting on Solar 新利手机客户端Chemistry and Photocatalysis: Environmental Applications held in Prague,Czech Republic,June 2010.
