According to a report by Huskic et al (2008), the first steps of enhancing the mechanical properties by simple melt processing shows promising results. Previous results of Murphy et al (Scripta Materialia, Vol. 54,  417–420, (2006)) have shown that the percolation threshold in drop cast PMMA/MoSI composites is around 10^-5, suggesting applications of MoSI/polymer composites such as transparent electrodes and conducting transparent coatings. </description></item><item><title>The race for high conductivity heats up.</title><pubDate>9/09/2008 0:00:00</pubDate><description>The conductivity of MoSi nanowires is thought to be limited by defects and imperfections. With improved processing techniques the conductivity of MoSI material has increased more than thousand fold in three years since the material was first synthesised in bulk quantities, until recently reaching values of 10 S/m. The current repeatably achieved values are around 2000 S/m for thin bundles. </description></item><item><title>MoSIx sensor demonstrated</title><pubDate>12/12/2007 0:00:00</pubDate><description>Mo6S3I6 nanowire networks change their resistance in response to the  presence of analyte vapors. The vapor sensing behaviour is quantitatively described very well phenomenologically in terms of the concentration of adsorbed analyte molecules in the contact tunneling junctions. The time-response of the sensor is observed to follow simple adsorption-desorption kinetics. The network sensor shows very clear selectivity, whereby the response is related to the dipole moment of the analyte. The response function favours rapid detection of small analyte concentrations. The work is described in the American Chemical Society journal Chemistry of Materials (to appear in early 2008)</description><link>http://complex.ijs.si/F7publications/Nanomagnetism.html</link></item><item><title>Field emission from large area MoSI emitters</title><pubDate>11/12/2007 0:00:00</pubDate><description>Vertically aligned bundles of molybdenum-sulphur-iodine nanowires (MoSIx) were 
grown on a molybdenum foil, thin wire and quartz substrate. By choosing different growth parameters 
we have been able to vary the surface density from ~0.01 to 0.5 bundles/µm2 and the length of the 
nanowire bundles from ~30 µm - 15 mm. In the case of growth on molybdenum, resistivity 
measurements show that a good electrical contact exists between the bundles and the metal substrate.

The nanowires are found to have excellent field emission properties, competitive with state-of-the-art 
carbon nanotube large-area field emitters. </description><link>http://link.aip.org/link/?JAP/102/114308</link></item><item><title>Optical limiting behaviour of MoSI nanowires</title><pubDate>10/06/2007 0:00:00</pubDate><description>Experiments performed using the open aperture Z-scan technique at 532 nm and 1064 nm show optical limiting behaviour of Mo6S4.5I4.5. The NLE was compared with that for a stabilized multi-walled carbon nanotube (MWNT)-polymer composite dispersion. 
The uniformity of the MoSI dispersion in terms of both diameter and electronic behaviour makes MoSI nanowires of particular interest.
