| 21. | :: You wouldn't be able to see the beam even in a reasonably high vacuum.
|
| 22. | Interstellar matter, considered dense in an astronomical context, is at high vacuum by laboratory standards.
|
| 23. | In ultra-high vacuum systems, some very odd leakage paths and outgassing sources must be considered.
|
| 24. | Ultra-high vacuum solves many of the problems that need to be considered during sample preparation.
|
| 25. | These characteristics are high ductility, high high vacuum.
|
| 26. | Liquid alkali metals as the heat transfer fluids are used as well as the ultra-high vacuum.
|
| 27. | Cutting-edge research that needs an ultra high vacuum requires a more sophisticated form of vacuum chamber.
|
| 28. | FEDs suffer from erosion of the emitters, and require extremely high vacuum in order to operate.
|
| 29. | This product is then heated at 350 �C under a high vacuum to produce ThCl 4.
|
| 30. | Apiezon or similar hydrocarbon based greases are the cheapest, and most suitable for high vacuum applications.
