Hi, a link list just to keep you occupied;-)
- From December 2011, but nevertheless interesting: critical comment by Joerg Heber, senior editor of Nature Materials, on Organic Solar Cells.
- Criticism of publisher Elsevier becomes louder again (some history of it in the previous link = Wikipedia entry): the mathematician Gowers speaks out in his blog post Elsevier — my part in its downfall (and a follow up post here), and PZ Myers rants Elsevier = Evil in his blog. There is even a website where you can sign upto protest against Elsevier’s practices of driving prices for their journals very high, thecostofknowledge.com. I have to admit I did not do it; just know a book appeared at Academic Press (which is an Elsevier brand) with a chapter written by me, and also I’d somehow feel strange to boycott one of the few journals (or even the only one?) on organic electronics by Elsevier, the one with just that name. Nevertheless, I agree that information should be made widely available, specifically if funded with public money. That is one of the reasons why I upload most of our articles to the arXiv.org e-print archive.
- Essay by Santiago Alvarez on the wide range of different arrows chemists use… Chemistry: A Panoply of Arrows.
- Adv Funct Mater editorial by Dave Flanagan: More Fundamental Understanding In Materials Science
- Nature News by Jim Giles, Going paperless: The digital lab on using Ipad as your notebook with commercial labbook software.
- Did I link to this nature education piece on English communication for scientists already? I particularly liked the comic on the first page;-)
- The voice of science: let’s agree to disagree by Daniel Sarewitz about the importance of disagreements.
Next week a round of referees will come to Würzburg to decide on another set of grant proposals, so I’ll go back to my preparations now…

data to determine which fraction of charges is lost to bimolecular recombination,

, they found 
. Although I was not able to follow the exact derivation (is it missing?!), it seems to work. Easy method, although make sure not to have too much space charge in your device – even at the contacts, induced by low (ohmic) injection barriers (we compared it to our device simulation, and then you get significant deviations)! In my opinion, the latter point is not stressed enough in the paper, despite the nice approach.
