1. One popular route started off from the highly reactive unsaturated hydrocarbon, ethylene (or ethene), H 2 C=CH 2, which was readily and cheaply available from petroleum refineries.
2. It separates the saturated part of the aquifer from the unsaturated zone above it.
3. The part of the aquifer that lies above the water table is termed the unsaturated zone.
4. A new report has been published by IAL Consultants on the European market for unsaturated polyesters.
5. In the dry or growing season, plants take water from the unsaturated zone.
6. Polyunsaturated fats may reduce the amount of fatty deposits in the arteries which cause atherosclerosis, and unsaturated fats, such as vegetable oils, are safer than animal (saturated) fats; soft margarine is better than butter or hard margarine.
7. EXCEPT where rocks are heavily cracked or fissured, it usually takes many years for water to find its way down through the soil and the unsaturated zone to the saturated zone of an aquifer.
8. But in the confined part of the aquifer, the spaces between mineral grains, every pore in fact, is filled with water: there is no unsaturated zone.
9. Rain entering the soil disturbs the equilibrium in the same way as water added to the top of the capillary tube or towel; water drains through the unsaturated zone to the water table.
10. Pople followed up this publication with two papers on the statistical mechanics of assemblies of axially symmetric molecules; interpretations of electron interactions in unsaturated hydrocarbons; collaboration (with Christopher Longuet Higgins) on the spectra of aromatic molecules on solvent spectral shifts; the theory of the Renner effect (Strong coupling between electronic and vibrational modes in a molecule leading to a breakdown of a Born-Oppenheimer approximation - it became a standard work); and his recognition of the value of NMR as a tool for chemistry is revealed in the early issues of Molecular Physics .
11. The nitrate problem has taught us that to protect our drinking water, we must monitor the unsaturated zone.
12. Saturated hydrocarbons can burn to aldehydes, alcohols to organic acids, and aromatics to unsaturated compounds which are pungent and irritating.
13. A catalyst that could convert methane to methanol or larger unsaturated hydrocarbons directly and at low temperatures would be of enormous commercial interest.
