The effect on surface-enhanced Raman scattering due to the increase in temperature of the metallic substrate is studied via a simple model for physisorbed molecules. Surface roughness is represented by a spherical or spheroidal island, and the temperature effects on the surface plasmon are accounted for via a slightly modified Ujihara model. It is found that the enhancement ratio in general dec...

A great variety of volatile-rich material is fed into subduction zones, including all sorts of marine sediment, altered oceanic crust and some serpentinized mantle lithosphere1. Subduction delivers these materials to depth, but their subsequent history depends on how pressure and temperature increase together. In the cool shallow subduction zone, !uids are liberated at subsolidus temperatures, ...

temperature is considered as the basic element of climate and also the environmental limiting factor in lutdesert. in this research, in order to identify the temperature of lut desert located in east of central iran, using remote sensing data, six series of modis sensor images related to june 24th & december 23rd 2002, and also january 22nd, march 22nd, june 22nd & september 24th 2003 w...
