The ability to probe structures and functional properties of complex systems at the nanoscale, both at their surface and in their volume, has drawn substantial attention in recent years. Besides detecting heterogeneities, cracks and defects below the surface, more advanced explorations of chemical or electrical properties are of great interest. In this

Catalysis and subsurface bonding
Physical Review B, 1988We analyze the data on hydrogen adsorption and catalyzed water formation on Pt surfaces. Evidence is obtained for the existence of a weakly bound subsurface state of H. A reaction mechanism involving subsurface hydrogen, which can explain the catalytic activity of Pt surfaces in hydrogenation reaction, is put forward.

Applications of Subsurface Microscopy
2012Exploring the interior of a cell is of tremendous importance in order to assess the effects of nanomaterials on biological systems. Outside of a controlled laboratory environment, nanomaterials will most likely not be conveniently labeled or tagged so that their translocation within a biological system cannot be easily identified and quantified ...

Evaluation of Sampling in the Subsurface
Water Resources Research, 1996The evaluation of sampling is presented in the form of a sampling error defined as a difference between the true average and the sampled average of the measured process over the sampling domain. The sampling error is quantified as a product between the process point variance (defined at the scale of a sampling device's support volume) and the sampling ...

Smoother subsurface scattering
SIGGRAPH 2009: Talks, 2009The irradiance-cached dipole diffusion approximation proposed by [Jensen and Buhler 2002] is a practical tool for capturing the subsurface scattering of many common materials in the context of film-quality rendering. One drawback of this model is the high irradiance point density it requires to attenuate sampling noise at low mean free paths, which can

Fundamentals of the Subsurface System
1999This book along with its companion book (Yeh, 1999) are concerned with the mathematical description and numerical modeling of subsurface media. It is about the subsurface media that control the movement of fluids (including water, nonaqueous liquids, and gas), the migration of chemicals, the transfer of heat, and the deformation of media.
