A great effort has been devoted into understanding the mechanisms of charge generation and charge separation processes in bulk heterojunction solar cells, with the aim of improving their performance. Theoretical methods, such as density functional theory (DFT), have been used to shed light into these complex processes, but the computational cost associated with the simulations limits the model size and thus its accuracy with respect to real heterojunctions. To overcome this limitation, a linear-scaling reformulation of time-dependent DFT is employed, allowing to move beyond the simple polymer–fullerene models and to consider larger complexes composed of more than a single oligomer chain and numerous fullerene molecules. In this work, the interaction between an analogue of PBTZT-stat-BDTT-8, a high-performance D–A statistical copolymer developed by Merck, and phenyl-C61-butyric acid methyl ester is explored, with a focus on (i) the effect of the size of the polymer’s acceptor (A) blocks and (ii) the effect of the domain size. Results suggest that large acceptor blocks enhance the probability of a charge transfer (CT) to occur and that CT states are more significantly affected by the size of the polymer rather than the fullerene phase. Evidence of long-range CT states in the low-energy part of the excited-state manifold is also observed

 Nov. 2009, No. 4 Look in the Library Catalog - From UNE Library homepage www.une.edu/library use the search box under “Search UNE Libraries Catalog”. If you know the title of the book you need,  change the drop-down menu to “title” and enter the title then search.  Example: Delivering Health Care in America: A Systems Approach. Scroll to the record that says “Electronic & Print Resource” and Click “Full Text” to get into the ebook. Or, search by Subject and look for electronic books that way. Example: Internal Medicine -- Electronic Book (currently there are 6 titles).Browse titles in an eBook Library- R2 Library -- Books@Ovid -- Access Medicine -- Thieme Electronic Book Library -- MDConsult -- STAT!Ref -- NetLibraryThese are all available from the library web site. Click “Databases by Title” then click the first letter of the database and scroll down to the one you need. Ever wonder how much •	energy your laptop, hair dryer, or TV use?

Some of them are exact copies of the physical book. Some of them have extra bells and whistles like interactive links, audio and video files, and hyperlinks to related information. Stay home in your pj’s and read part of a reference book or even a required text for your class on your computer.  So how do you find these eBooks, you ask?

Full disclosure: I took Latin in high school, considered a Classics major in college, and visited Rome and Athens on my own while in college, so I might be a bit obsessed about the time period. It’s a really neat depiction of the time when Rome was in transition from Republic to Empire, entirely fictionalized and probably more sexualized than needed, but a great cross-section of Roman citizens: both the  upper classes (the family of Julius Caesar and his adopted successor: Octavian) and several plebeian Romans, who in the second season start a gang that acts a whole lot like the mafia. So if you like history,  costume drama, or just a good and convoluted plot, I would recommend it!
