Instrumentation for beam line X2 at the National Synchrotron Light Source is described. The beam line is configured as a dedicated experimental station whose design has been optimized for carrying out both microtomography and microradiography. The fa

Guided propagation of neutrons in thin films was directly observed in a ${\mathrm{TiO}}_{2}$/Ti/Si waveguide by exciting one of its discrete guided modes from an external neutron beam. The condition found experimentally for exciting this particular m

We use ultrasonic attenuation and light scattering to study spatial correlations in the pores of Vycor on filling and draining with hexane. On filling, the hexane initially adsorbs uniformly, but when capillary condensation occurs, vapor microbubbles

We present experimental evidence for achieving significant x-ray flux enhancement by coupling a highly collimated and monochromatic synchrotron x-ray beam into a Si/polyimide/SiO 2 thin-film waveguide. The observed 20-fold flux increase agrees with t

Artifacts dominate atomic force microscope (AFM) images of nanoporous and mesoporous inorganic oxide materials taken under ambient atmospheric conditions with currently available tips. Artifacts in these AFM images are attributed to tip-sample intera

We have imaged micron sized silicalite crystals with an atomic force microscope (AFM). High resolution images taken in the repulsive mode show a periodic pattern that locally has a symmetry and periodicity which can be mapped onto the expected image

We have developed and used a simple lithographic technique that allows preparation of TEM sections from a variety of materials in 10–45 minutes. To obtain TEM sections, 50–5,000 Å diameter cylindrical post structures are microfabricated on the s
