    Abstract: The present disclosure provides a method for preparing a perovskite quantum dot film by one-step crystallization, and belongs to the field of perovskite quantum dot material technology. The present disclosure uses adamantanemethylamine and hydrohalic acid as ligands, first mixes a cesium halide, a lead halide, and the ligands with a solvent to obtain a precursor solution, then deposits the precursor solution on a substrate, and then heats the substrate to obtain the CsPbX3 perovskite quantum dot film. The present disclosure uses adamantanemethylamine and hydrohalic acid as the ligands, which can quickly coat the perovskite, complex with the CsPbX3 perovskite, and directly form the perovskite quantum dot via a strong steric effect. Further, the present disclosure is simple and inexpensive, can directly obtain a high-quality perovskite quantum dot film with a thickness of more than 500 nm by one-step crystallization.

    Abstract: The present invention relates to covalently bonded fullerene-functionalized carbon nanotubes(CBFFCNTs), a method and an apparatus for their production and to their end products. CBFFCNTs are carbon nanotubes with one or more fullerenes or fullerene based molecules covalently bonded to the nanotube surface. They are obtained by bringing one or more catalyst particles, carbon sources and reagents together in a reactor.

    Abstract: An apparatus for explosively removing at least one coating from a lengthwise section of an optical fiber includes: a heater for heating a heating region to above a thermal decomposition temperature of the at least one coating; a securing mechanism for securing the optical fiber so that the lengthwise section is positioned in the heating region; and a controller operatively associated with the heater. The controller is configured for: causing the heater to heat the heating region to above the thermal decomposition temperature for a sufficient duration so that the at least one coating is explosively removed from the lengthwise section of the optical fiber in the heating region; and deactivating the heater before the explosive removal of the at least one coating from the lengthwise section.
