Voorbeelden van cesium

• Cesium in the intracellular solution blocks potassium channels like delayed rectifier and inactivating potassium channels.

• Intracellular cesium separates two glutamate conductances in retinal bipolar cells of goldfish.

• Potassium was used in place of cesium so that current-clamp recordings could be made, but current-clamp data is not presented here.

• Extracellular cesium ions alone blocked the inward current but exerted no effect on the photoresponses.

• Then, we broke through the membrane with a cesium methanesulfonate-based internal solution.

• The inward rectification was eliminated by extracellular cesium (data not shown).

• Unfortunately, these upland soils are very thin and not suited to locking away the cesium.

• There will possibly be a lot of unlocked cesium available in the soil for uptake this spring.

• The source is typically the radioactive isotope cesium-137, with a half-life of about 30 years.

• Frlez et al. recently reported using tomographic methods to track the passage of cosmic rays muons through cesium iodide crystals for quality control purposes.

• The metallic titanium provides reducing conditions during ceramic synthesis and helps decrease volatilisation of radioactive cesium.

• Later rubidium beam and cesium beam clocks were used.

• The earliest sensors were scintillation detectors, with photomultiplier tubes excited by (typically) cesium iodide crystals.

• A thin gas of cesium atoms is released into the cavity where they are exposed to microwaves.

• Indirect detectors contain a layer of scintillator material, either gadolinium oxysulfide or cesium iodide, which converts the x-rays into light.
