Hosts interchange

Phthalocyanines have attracted particular attention as potential surface modifiers due to their stability and tendency to form ordered structures directed by dispersion forces. They are inherently host-guest structures with a readily interchangeable coordinating metal ion, which in the solid state results in a tunable bandgap. At a surface, in addition to possibly interesting electronic...

The essence of the simplification discussed here is the assumption that the oscillator-host interaction is dominated by the host atoms nearest to the atom, the so-called first solvation shell of host atoms. In a solid host these atoms are fixed, while in a liquid they may interchange with other host atoms on the timescale of the observed relaxation. However, the argument used here relies mainly on the number of nearest atoms, not on their identity, and while tins number may fluctuate somewhat in a liquid its average provides a reasonable measure for the interaction experienced by the oscillator. 

EDI-. Electronic data interchange, a host of formats standardized by various interest groups under ANSI to exchange commercial information of different types among companies who wish to do business with each other electronically. 

All communication relies on the existence of sets of rules or protocols that govern what form the communication may take and how it will be understood. Computer communication generally requires a very tightly defined rule set. The transmission control protocol (TCP), which is universal across the Internet, defines how data is reliably transmitted and received by Internet hosts. It does not define how those hosts manipulate the data they send or receive. The Web requires a mechanism whereby a browser can request a document and a server can deliver it. This type of interchange will also require a server to reply that a document (for a variety of reasons) is unavailable. The protocol that enables such interchanges is HTTP. This was built on top of the Internet s TCP protocol (it was, however, designed to be compatible with other similar protocols).
