Lastly, it needs to be covered with a layer of non-porous, non-cracked rock to provide a leakproof cap.So far, only three successful CCS projects are under way.
Technical challenges remain, including integrating a leakproof backup battery into the device and miniaturising the FREE-D's control electronics.
This separation requires leakproof junctions between cells.
The application of welding to join pipes in the 1920s made it possible to construct leakproof, high-pressure, large-diameter pipelines.
Tight junctions form leakproof seals by fusing the plasma membranes of adjacent cells, creating a continuous barrier through which molecules cannot pass.
Tight junctions also hold cells together, but they form a nearly leakproof intercellular seal by fusion of adjacent cell membranes.
An important breakthrough in gas-transportation technology occurred in 1890 with the invention of leakproof pipeline coupling.
The Dutch anthropologist Carel van Schaik found that orangutans could perform tasks which were well beyond chimpanzees, such as making rain hats and leakproof roofs for their nests.
Apron conveyors consist of endless chains with attached overlapping and interlocking plates to provide a continuous-carrying surface that forms a leakproof bed suitable for bulk materials without containers.
The Supreme Court is still one of the few relatively leakproof institutions in Washington, so the search for clues about when the ruling might come became desperate.
