    摘要： In an embodiment, a method for manufacturing a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to acidified water vapor or immersion in a concentrated acid bath (e.g., HCl and methanol). At least a portion of the elongated nanostructures may be removed after being coated. Embodiments for TLC plates and related methods are also disclosed.

    摘要： A camera tripod rotating head (20) is taught that is used for taking 360 degree photographic images with a camera (22) mounted on a tripod (24). The rotating head consists of an adapter base (26) that is configured to mate and attach to the camera tripod, and includes a one way roller clutch (30) mounted within the adapter base and a shoulder bolt (32) that is positioned through both the base and the clutch. A rotating beam (36) is attached to the adapter base with the shoulder bolt allowing the beam to revolve around the base a full 360 degrees in one direction only. Detents are position within the adapter base relative beam allowing the beam to be rotated and stopped at an equidistant predetermined location, preferably sixteen, until manually urged to the next location. An adjustable camera mounting bracket (60), configured to mate with the camera, is manually attached to the rotating beam permitting the rotating head, with a camera attached, to sweep in a one way arc of rotation stopping by the detents at each predetermined position.
