scanning near-field optical microscopy (snom) is a member of scanning probe microscopes (spms) family which enables nanostructure investigation of the surfaces on a wide range of materials. in fact, snom combines the spm technology to the optical microscopy and in this way provide a powerful tool to study nano-structures with very high spatial resolution. in this paper, a qualified overview of ...

Nowdays,  iron  nanoparticles  due  to  their  unique  characteristics  are used  in  all  of  sciences  and  technology.  These  nano  particles  due  to their  electrical, magnetic,  optical  and  catalytic  properties  and  having high  area  and  activity  that  is  promped  by  their  small  size  and most importantly  many  scientists  from  the  entire  world  are  interested  in th...

Using nano-technology materials in the asphalt pavement industry is new compared with Portland cement concrete. The main objective of this study is to investigate the effects of nano-silica modification on some properties of a penetration grade asphalt cement and a typical asphalt concrete. 60/70 penetration grade bitumen was modified with different percentages of nano-silica (i.e. 1, 3 and 5%,...

The topic of this project belongs to focus area #3 of the NSF solicitation: " Micro/Nanoscale Phenom-enology and Metrology. " Nano-structured materials are extremely attractive for applications requiring high strength and ductility. Two such areas are: (1) nano-layered composites for future aerospace applications demanding high strength-to-weight ratios; and (2) next-generation interconnect and...
