-nanowires. ​blah blah+nanowires. ​We find the optimum interwire distance depends on 
 +composition and to a smaller degree on the orientation of the wires.  
 +Structural order is expected in bundles with x=0 and x=6,  
 +since there is no disorder in the decoration of the Mo clusters.  
 +In bundles with other stoichiometries we expect structural disorder to occur.  
 +We find that the electronic structure of some nanowires can be switched  
 +from metallic to semiconducting by changing the interwire separation.  
 +Also, we find that selected stable or metastable nanowire geometries exhibit  
 +ferromagnetic behavior. 
 +The most intriguing changes occur in nanowires with x=4.5 and 6,  
 +which change from metal to semiconductor or undergo a magnetic transition  
 +upon axially stretching or compressing the nanowires or upon changing  
 +the inter-wire separation.\\
