摘要:
Graphitic structures have been prepared by exposing templates (metal, metal-coated ceramic, graphite, for example) to a gaseous mixture that includes hydrocarbons and oxygen. When the template is metal, subsequent acid treatment removes the metal to yield monoliths, hollow graphitic structures, and other products. The shapes of the coated and hollow graphitic structures mimic the shapes of the templates.

摘要:
A method for closing a child application window of a parent window. An indicator is instantiated in data loaded into the parent window, followed by performance of a loop. In each iteration of the loop: (a) if it is ascertained that the data currently loaded into the parent window includes the indicator, then pausing of a first number of seconds is followed by looping back to perform the next iteration, otherwise pausing of a second number of seconds is followed by determining whether the data currently loaded into the parent window includes the indicator; (b) if it is determined that the data currently loaded into the parent window includes the indicator, then pausing of the first number of seconds is followed by looping back to perform the next iteration, otherwise the loop is exited and the child application window is closed during a final iteration.

Exemplary embodiments provide materials and methods for forming graphene-based exfoliated products with low oxygen contents by a reductive-expansion reaction from a physical mixture containing graphite-based precursor(s) and a chemical agent. Exemplary embodiments also provide materials and methods for forming graphene-based exfoliated products with controllable amounts of nitrogen and/or other impurities incorporated in the material structure as a result of a reductive-expansion reaction from a physical mixture containing graphite-based precursor(s) and a chemical agent.
摘要:
Disclosed is a process for making a composite material that contains core-shell structured nanoparticles. The process includes providing a precursor in the form of a powder a liquid and/or a vapor of a liquid that contains a core material and a shell material, and suspending the precursor in an aerosol gas to produce an aerosol containing the precursor. In addition, the process includes providing a plasma that has a hot zone and passing the aerosol through the hot zone of the plasma. As the aerosol passes through the hot zone of the plasma, at least part of the core material and at least part of the shell material in the aerosol is vaporized. Vapor that contains the core material and the shell material that has been vaporized is removed from the hot zone of the plasma and allowed to condense into core-shell structured nanoparticles.
摘要:
An intramedullary nail (20) and related method for fixing a fracture in a long bone. The nail (20) comprises an elongate member (22) having a longitudinal axis (54), a proximal end section (32), a distal end section (34) and a solid central section (24) extending between the proximal and distal end sections (32, 34). The proximal and distal end sections (32, 34) respectively include proximal and distal fastener receiving areas (28, 30) of greater cross sectional dimensions than the central section (24). Each fastener receiving area (28, 30) includes at least one hole (50, 52) extending transverse to the longitudinal axis for receiving a cross fastener (110) adapted to secure to the bone on opposite sides of the elongate member (22). The proximal and distal end sections (32, 34) thereby provide rigid anchoring locations relative to the central section (24) and the central section provides flexibility to promote healing of the fracture.
摘要:
A hollow carbon sphere having a carbon shell and an inner core is disclosed. The hollow carbon sphere has a total volume that is equal to a volume of the carbon shell plus an inner free volume within the carbon shell. The inner free volume is at least 25% of the total volume. In some instances, a nominal diameter of the hollow carbon sphere is between 10 and 180 nanometers.
摘要:
There is disclosed a process for producing metal oxide nanoparticles. The process includes the steps of: a) providing at least two precursor metal salt materials, b) passing the at least two precursor metal salt materials through a plasma torch forming a vaporized material, and then c) condensing the vaporized material forming a metal oxide nanoparticle.
摘要:
A method for showing a user navigating to a first website a collection of other websites relating to the first website comprising: identifying a first, second and third user having navigated to the first website; collecting navigation history tails from the first, second and third users, the navigation history tails identify websites navigated to by the first, second and third users, the navigation history tails further have an identification of each of the users; combining the navigation history tails to form a cumulative navigation history tail; generating a rank of some of the websites identified in the cumulative navigation history tail, the rank indicating a popularity of some of the websites identified in the cumulative navigation history tail; and providing the rank to an applet so the applet can generate an indication of websites based on the rank.
