Two-dimensional PbSe nanocrystal arrays on silicon nitride membranes were investigated using electrostatic force microscopy (EFM) and transmission electron microscopy (TEM). Changes in lattice and transport properties upon annealing in a vacuum were revealed. Local charge transport behavior was directly imaged by EFM and correlated to nanopatterns observed with TEM. Charge transport through nan...

in this paper, we propose a simple, fast, and accurate method to make scientific illustrations specimens of animals. photos and/or pencil drawings provided via microscope or stereo-microscope equipped with camera lucida and scanned. the scanned illustrations were  imported into coreldraw. the detailed drawings are made using special pens and proper lines. the final produced illustrations with t...

In this paper, we describe the implementation of a caching scheme for ad hoc networks. In this scheme the mobile nodes implement a local cache. This feature allows to intercept the forwarding requests and serve the documents requested directly using their local cache. Using the information obtained by the documents forwarded the nodes can redirect the requests to other nodes that are known to h...
