Allocated to the holes are wearing-protection inserts, having holes which are in alignment with the holes in the base body. The inserts which are disposed to adjoin each other in a row have a chordal surface where they are turned toward an adjoining insert and are provided with at least one surface of an arcuate segment of a cylinder laterally of the chordal surface.

摘要： A method for fabricating a nanostructure utilizes a templated monocrystalline substrate. The templated monocrystalline substrate is energetically (i.e., preferably thermally) treated, with an optional precleaning and an optional amorphous material layer located thereupon, to form a template structured monocrystalline substrate that includes the monocrystalline substrate with a plurality of epitaxially aligned contiguous monocrystalline pillars extending therefrom. The monocrystalline substrate and the plurality of epitaxially aligned contiguous monocrystalline pillars may comprise the same or different monocrystalline materials. The method provides the nanostructure where when the monocrystalline substrate and the plurality of epitaxial aligned contiguous monocrystalline pillars comprise different monocrystalline materials having a bulk crystal structure mismatch of up to about 10 percent, lattice mismatch induced crystal structure defects may be avoided interposed between the monocrystalline substrate and the plurality of epitaxially aligned contiguous monocrystalline pillars, which may have an irregular sidewall shape.

摘要： Movement of a gel structure is propagated by successively applying external stimuli to cause volume phase transition in the gel structure by alternately causing the gel structure to collapse and swell to move the center of mass of the gel structure in the direction of successive stimuli application. The movement is mediated by confining structure for the gel and anchoring—the starting side of the gel in the swelling cycle.

摘要： A block copolymer, preferably a block copolymer such as poly(isoprene-block-ethylene oxide), PI-b-PEO, is used as a structure directing agent for a polymer derived ceramic (PDC) precursor, preferably a silazane, most preferably a silazane commercially known as Ceraset. The PDC precursor is preferably polymerized after mixing with the block copolymer to form a nanostructured composite material. Through further heating steps, the nanostructured composite material can be transformed into a nanostructured non-oxide ceramic material, preferably a high temperature SiCN or SiC material.

摘要： The invention generally relates to fluorescent nanoparticles and more specifically to silica-based fluorescent nanoparticles of less than 30 nm with covalently attached organic dyes. The invention provides a fluorescent monodisperse silica nanoparticle comprising fluorophore center core and a silica shell wherein the radiative properties of the nanoparticle are dependent upon the chemistry (composition) of the core and presence of the silica shell. In one aspect of the invention, the core-shell architecture provides an enhancement in fluorescence quantum efficiency. The invention generally provides control of photophysical properties of dye molecules encapsulated within silica particles with sizes down to 30 nm and below. This control is accomplished through changes in silica chemistry and particle architecture on the nanometer size scale and results in significant brightness enhancement compared to free dye.

摘要： Highly crystalline metal oxide-carbon composites, as precursors to thermally stable mesoporous metal oxides, are coated with a layer of amorphous carbon. Using a ‘one-pot’ method, highly crystalline metal oxide-carbon composites are converted to thermally stable mesoporous metal oxides, having highly crystalline mesopore walls, without causing the concomitant collapse of the mesostructure. The ‘one-pot’ method uses block copolymers with an sp or sp2 hybridized carbon containing hydrophobic block as structure directing agents which converts to a sturdy, amorphous carbon material under appropriate heating conditions, providing an in-situ rigid support which maintains the pores of the oxides intact while crystallizing at temperatures as high as 1000 deg C. A highly crystalline metal oxide-carbon composite can be heated to produce a thermally stable mesoporous metal oxide consisting of a single polymorph.
