Abstract: A nanostructure is provided that in one embodiment includes a cluster of cylindrical bodies. Each of the cylindrical bodies in the cluster are substantially aligned with one another so that their lengths are substantially parallel. The composition of the cylindrical bodies include tungsten (W) and sulfur (S), and each of the cylindrical bodies has a geometry with at least one dimension that is in the nanoscale. Each cluster of cylindrical bodies may have a width dimension ranging from 0.2 microns to 5.0 microns, and a length greater than 5.0 microns. In some embodiments, the cylindrical bodies are composed of tungsten disulfide (WS2). In another embodiment the nanolog is a particle comprised of external concentric disulfide layers which encloses internal disulfide folds and regions of oxide. Proportions between disulfide and oxide can be tailored by thermal treatment and/or extent of initial synthesis reaction.
