While small amounts of materials like zinc or silicon are required to produce thin film devices, Cadien says the costs are not insignificant — they can come in at $ 500 or $ 600 per gram and the current processes are wasteful, dosing surfaces with anywhere from 100 to 10,000 times the molecules required.
«Usually there's a trade - off,» explains Feinberg, «because when the systems
dispense smaller amounts of material, we have more control and can print small items with high resolution, but as systems get bigger, various challenges arise.
You only need a relatively small amount of stuff — a
relatively small amount of materials, a relatively small amount of waste and a relatively small amount of land to generate lots of energy.
The needle collected
a small amount of material that the robot deposited in a nearby mass spectrometer, which is a powerful tool for determining a substance's chemical composition.
This allows pathologists to diagnose the existence of cancer, but the sample tends to be very small, and there's been some debate about how useful
that small amount of material can be for molecular testing,» Aisner says.
Simply place
a small amount of material into the steel mesh canister and submerge into a cup of hot water to brew your favorite infusion.
Occassionally, perhaps once a day, she may regurgigate
a small amount of material within an hour or so of one her four daily feedings.
Remember that
a small amount of this material can be seen in normal rabbit urine as it dries as a consequence of clearing excess calcium from the body.
Even
a small amount of material can be toxic to pets, so owners need to be vigilant about exposure to any type of raisin or grape, either raw or cooked.
In this test, called the allergy skin test or intradermal test,
small amounts of materials that routinely cause allergies in dogs are injected under the skin.
Copying something in its entirety is not Fair Use, either; Fair Use is the use of
a small amount of material, not a complete work.
