Surface chemistry is the study of chemical phenomena that occur at the interface of two phases, between a gas, usually the atmosphere, and a solid or between a liquid and a solid.

Surface chemical research is closely related to surface functionalization, which aims at modifying the chemical composition of a surface by incorporation of selected elements or functional groups that produce various desired effects or improvements in the the properties of the surface or interface.

The adhesion of gas or liquid molecules to the surface is known as adsorption, which can is due to either chemisorption or by physisorption. Surface chemistry is of particular importance to the field of heterogeneous catalysis.

Reduction of nonhomogeneous quasilinear 2 x 2 systems to homogeneous and autonomous form
Carmela Curro and Francesco Oliveri By using the invariance with respect to suitable Lie groups of point transformations, necessary and sufficient conditions are determined allowing one to map through an invertible point transformation nonhomogeneous and nonautonomous quasilinear 2 x 2 systems to homogeneous and autonomous form. The p ... [J. Math. Phys. 49, 103504 (2008)] published Fri Oct 10, 2008.
Adiabatically switched-on electrical bias and the Landauer--B[u-umlaut]ttiker formula
H. D. Cornean, P. Duclos, G. Nenciu, and R. Purice Consider a three dimensional system which looks like a cross connected pipe system, i.e., a small sample coupled to a finite number of leads. We investigate the current running through this system, in the linear response regime, when we adiabatically turn on an electrical bias between leads. The mai ... [J. Math. Phys. 49, 102106 (2008)] published Fri Oct 10, 2008.
Lower spectral branches of a spin-boson model
Nicolae Angelescu, Robert A. Minlos, Jean Ruiz, and Valentin A. Zagrebnov We study the structure of the spectrum of a two-level quantum system weakly coupled to a boson field (spin-boson model). Our analysis allows to avoid the cutoff in the number of bosons, if their spectrum is bounded below by a positive constant. We show that, for small coupling constant, the lower pa ... [J. Math.
