| To achieve this, they spread specifically designed halogen-substituted monomers on gold and silver surfaces under ultrahigh vacuum conditions. These are linked to form polyphenylene chains in a first reaction step. |
| The area along ASR Sue is also full of communication dead zones, which are areas where very-high frequency and ultrahigh frequency signals do not propagate. |
| Sputter ion pumps have a long life and can provide ultrahigh vacuum, free of organic contamination and vibration. |
| To accomplish this, a comparatively wide transmission channel is needed, and the carrier must be an ultrahigh or superhigh frequency. |
| Liquid methylcyclohexane, for example, absorbs sound of ultrahigh frequency. |
| The tool, which turned up in Holland, is the oldest tool to be discovered in Europe made from the rare alloy, ultrahigh carbon steel. |
