GQW articles: MAY 2013 edition

201305GQW

I can’t believe is almost September already and I still haven’t posted the list of articles for last May (I mean, the previous one took me a year, but I’m trying to improve on that…). Hopefully I’ll have this brief “panoramic” overview of May’s articles finished later this week, but just in case, here is the plain list of the 30 papers published that month, roughly classified by categories as follows:

  • (B). GQ-Biology: 9 articles
  • (C). GQ-Cations: 1 articles
  • (M). GQ-Methods: 6 articles
  • (NT). GQ-Nano & Technology: 7 articles
  • (R). GQ-Recognition. 5 articles
  • (SD). GQ-Structure & Dynamics: 8 articles
  • (S). GQ-Supramolecular: 2 article

Similar to April, studies related to the biological role of GQs continue to dominate the list this month, but there are almost as many contributions on structure & dynamics (SD) and nano & technology (NT) categories. GQ-Recognition (R) always get steady stream of papers, while less common categories (e.g., cations and supramolecular) had at least a few.
