Restricted-flow junction between liquids

Allowing a liquid to seep through a long crack in glass provides means for restricting its flow for long periods without attention. The length of the crack prevents the plugging to which capillaries are susceptible.

Microorganisms detected by enzyme-catalyzed reaction

Enzymes detect the presence of microorganisms in soils. The enzyme lysozymi is used to release the enzyme catalase from the microorganisms in a soil sample. The catalase catalyzes the decomposition of added hydrogen peroxide to produce oxygen which is detected manometrically. The partial pressure of the oxygen serves as an index of the samples bacteria content.

Metals plated on fluorocarbon polymers

Electroplating lead on fluorocarbon polymer parts is accomplished by etching the parts to be plated with sodium, followed by successive depositions of silver and lead from ultrasonically agitated plating solutions. Metals other than lead may be electroplated on the silvered parts.
