Monodisperse colloidal SiO2 submicrospheres were prepared by hydrolysis and condensation of tetraethoxysilane. We measured various relative settle velocities of different aggregated submicrospheres and then developed a submicrospheres selection techn

We present a scanning electron microscopy (SEM) investigation of artificial opals prepared by the sedimentation of suspension with sub-micrometer silica spheres. An analysis of the SEM images confirms that the fcc stacking is the most stable phase fo

Photodesorption of CO, NO, and O2 from modified Ni(111) surfaces has been studied. Both direct observation of photodesorption and postirradiation thermal desorption measurements have been carried out. In each case, the photodesorption process is firs

The P–F symmetric stretch fundamental mode of PF3 chemisorbed on the Ni(111) surface has been measured with Fourier transform infrared reflection absorption spectroscopy. Strong adsorbate–adsorbate interactions lead to a net increase in frequency
