    • Atomic scale study of superlow friction between hydrogenated diamond surfaces 

      Dag, S.; Ciraci, S. (American Physical Society, 2004)
      Strong attractive interaction between two clean diamond (001) slabs turns repulsive upon the hydrogenation of surfaces. This repulsive interaction serves as if a boundary lubricant and prevents the sliding surfaces from ...

    • Cyclodextrin nanofibers by electrospinning 

      Celebioglu A.; Uyar T. (Royal Society of Chemistry, 2010)
      We have demonstrated that cyclodextrin (CD) (a non-polymeric system) can be electrospun into nanofibers by itself; methylbeta-cyclodextrin (MbCD) nanofibers were electrospun and it was observed that the success of the ...
