The cyclic process. A process in which a system goes from an initial state to a final state and returns back to the initial state is called a cyclic process. The net energy change in a cyclic process is zero. That means, in a cyclic process, the system starts and returns to the same thermodynamic state.

Cycloaddition Reactions Hoffmann, R.; Woodward, R. B. J. Am. Chem. Soc. 1965, 87(9), 2046-2048. Whereas electrocyclic reactions involve the net intramolecular interconversion of one σ-bond and one π-bond, cycloaddition reactions consist of the net intermolecular conversion of k π-bonds to k σ-bonds to form a cyclic product. mn -2n
INTRODUCTION: Any of a major class of organic chemical compounds characterized by the fact that some or all of the atoms in their molecules are joined in rings containing at least one atom of an element other than carbon.The cyclic part of heterocyclic indicates that at least one ring structure is present in such a compound, while the prefix hetero refers to the noncarbon atoms, or heteroatoms.
Recyclable SDAs. Current methods for zeolite synthesis use organic molecules as their SDAs. Once the synthesis is complete a high temperature combustion step is required to remove these SDAs from the zeolite framework. This process both destroys the SDA, a high cost material, and the energy release and the water produced in the combustion can damage the inorganic structure.
