Popis:	A bola-amphiphile surfactant, containing a carboxylic acid at one end of the molecule and a thiol at the other, was bonded to nanoparticles of amorphous iron. The bonding of both functional groups was verified by FTIR and XPS measurements. TPD measurements exhibited three temperatures at which molecules are removed from the surface of the iron nanoparticles. The highest temperature, ca. 360°C, is assigned as the temperature at which molecules bonded simultaneously at both ends are desorbed from the surface.
