Anne over at Highly Allochthonous has inspired me to try writing a literature post following her pick of November’s papers in her field post. While she likes emailed table of contents from new journal issues, I can’t stand the things – too many emails already. I’ve tried RSS feeds for journals and I don’t like them either – particularly if reliant on keywords/selecting specific journals. Maybe I’m old fashioned but I like spending time every so often foraging through recent issues and online articles (ahead of publication). Things catch my eye that I wouldn’t see on a keyword search – and I think that’s quite important when your research falls between two clearly defined areas – you don’t always know all the latest terminology to effectively search for relevant literature. I rooted out the following papers today from the Journal of the American Chemical Society As Soon As Publishable Articles (ASAP):
“Near-Infrared Luminescent Lanthanide MOF Barcodes” White et al. DOI: 10.1021/ja907885m
MOFs are metal-organic frameworks and are solids where organic groups with suitable ligands (amine, carboxylic acid) and rigidity are linked together by metal ions forming honeycomb like structures. By controlling the chemistry of the ligand and the choice of the metal, different properties can be imparted into the structure. Here the authors have prepared a series of MOFs using different lanthanide metal centres to link the groups together. Lanthanide cations are well known for giving specific emission spectra, and by using a predetermined mixture of cations frameworks that will give unique spectral fingerprints (or barcodes) can be synthesized.
“Duck-Billed Platypus Venom Peptides Induce Ca2+ Influx in Neuroblastoma Cells” Kita et al. DOI: 10.1021/ja908148z
Well it was the title – who could scroll past a paper about Duck-Billed Platypus Venom and Neuroblastoma Cells? This paper describes the purification and characterization of several novel peptides found in the venom.
I will expand my literature search to other journals…
