"The aim of Nanojournal.org web site is to reference all nanotechnology articles from several research journals. This database gives references (and links) of papers about nanotechnology, from selected scientific journals (PRB, PRL, JACS, JAP, JPCB....) [The] database is [...] a way to obtain the latest news in the area of nanotechnology.

Many of the papers will require an electronic subscription to the referenced publication, or at least a site registration. Further, these papers tend to be highly technical and specific in nature. (The typical PRL paper is for a rather different audience than an article in Scientific American.)
