摘要:
This invention provides a method of making single-wall carbon nanotubes by laser vaporizing a mixture of carbon and one or more Group VIII transition metals. Single-wall carbon nanotubes preferentially form in the vapor and the one or more Group VIII transition metals catalyzed growth of the single-wall carbon nanotubes. In one embodiment of the invention, one or more single-wall carbon nanotubes are fixed in a high temperature zone so that the one or more Group VIII transition metals catalyze further growth of the single-wall carbon nanotube that is maintained in the high temperature zone. In another embodiment, two separate laser pulses are utilized with the second pulse timed to be absorbed by the vapor created by the first pulse.

摘要:
Herein is described Nanostructure Enhanced X-ray Therapy (NEXT), which uses nanomaterials as radiosensitizers to enhance electromagnetic radiation absorption in specific cells or tissues. The nanomaterial radiosensitizers emit Auger electrons and generate radicals in response to electromagnetic radiation, which can cause localized damage to DNA or other cellular structures such as membranes. The nanomaterial radiosensitizers contain moieties for specific targeting to molecules or structures in a cell or tissue, and can be functionalized for increased stability and solubility. The nanomaterial radiosensitizers can also be used as detection agents to help in early diagnosis of disease. Together with known techniques such as Computed Tomography or Computerized Axial Tomography (CT or CAT scan), these nanomaterial radiosensitizers could allow early diagnosis and treatment of diseases such as cancer and HIV.
摘要:
The inertia wheel contains a left piece having its circumference extended rightward into a first ring side wall with a left-high-right-low step between a left side of the left piece and the first ring side wall, and a right piece having its circumference extended leftward into a second ring side wall. The second ring side wall wraps the first ring side wall and a left end of the second ring side wall tightly interfaces the step of the first ring side wall. An axle tube is inserted in a first through hole and a second through hole of the left and right pieces, respectively. The inertia wheel as described is simple, robust, low-cost, low-carbon, appealing, and adaptable.
