Perturbation theory for Green’s functions as an effective mass formalism

Journal of Mathematical Physics, 1977
A formal solution for Green’s functions of the type [∂2+m2+gV (x)]G (x,y) =δ (x−y) is presented which has the structure of an effective mass formalism. One first solves the free case [gV (x) =0] for given boundary conditions and then replaces the parameter m in the solution by a quantity depending on V (x).

Development of Solvent-Free Ambient Mass Spectrometry for Green Chemistry Applications

Analytical Chemistry, 2014
Green chemistry minimizes chemical process hazards in many ways, including eliminating traditional solvents or using alternative recyclable solvents such as ionic liquids. This concept is now adopted in this study for monitoring solvent-free reactions and analysis of ionic liquids, solids, and catalysts by mass spectrometry (MS), without using any ...

Green mass finishing with dry abrasive and polishing media

Metal Finishing, 2007
Summary Dry media mass finishing processes can be used to produce refined edge and surface effects. These processes are not as well known as conventional processes that make use of aqueous solutions in concert with abrasive media. Although not universal in potential applications, these materials and methods should be investigated as a potential ...

GREEN ELEMENT DESCRIPTION OF MASS TRANSFER IN REACTING SYSTEMS

Numerical Heat Transfer, Part B: Fundamentals, 1996
A novel and straightforward methodology is developed for the dynamics of mass transfer in reacting systems. The technique is derived using the Green's identity to implement the singular integral theory of the boundary-element method (BEM) in an element-by-element fashion.
