| 31. | The technique is most commonly performed as powder diffraction, which only requires a polycrystalline powder.
|
| 32. | Starship hulls are constructed using a " polycrystalline alloy " more durable than most conventional materials.
|
| 33. | As a result, turbine blades are typically monocrystalline or polycrystalline with a preferred crystal orientation.
|
| 34. | Single crystal nanorods and polycrystalline nanotubes of lead selenide have been synthesized via controlled organism membranes.
|
| 35. | In 1986 Kienzle developed the first solar watch with light conditions and a polycrystalline solar element.
|
| 36. | Polycrystalline cells can be recognized by a visible grain, a " metal flake effect ".
|
| 37. | Grain size has been shown to have an effect on the efficiency of polycrystalline solar cells.
|
| 38. | Most inorganic solids are polycrystalline, including all common metals, many ceramics, rocks and ice.
|
| 39. | Sulfur, while usually polycrystalline, may also occur in other allotropic forms with completely different properties.
|
| 40. | Surface features and polycrystalline surfaces add complexity or change RHEED patterns from those from perfectly flat surfaces.
