The present invention relates to a conductive two-dimensional polyaniline (PANT) nanosheets template. The method comprises polymerizing aniline on an ice surface. The PANI nanosheets show distinctly high current flows of 5.5 mA at 1 V and a high electrical conductivity of 35 S/cm, which mark a significant improvement over previous values on other PANIs reported over the past decades. These improved electrical properties of the PANI nanosheets are attributed to the long-range ordered edge-on -stacking of the quinoid ring, ascribed to the ice surface-assisted vertical growth of PANI. The PANI nanosheet can be easily transferred onto various types of substrates via float-off from the ice surfaces. In addition, PANI can be patterned into any shape using predetermined masks, and this is expected to facilitate the eventual convenient and inexpensive application of conducting polymers in versatile electronic device forms.

A A molar toy contains: a body and an annular member. The body is made of flexible material and is formed in a capsule shape, and the body includes a hollow cavity defined therein, a first opening and a second opening which communicate with the hollow cavity and exterior environment. The annular member is inserted into the first opening and the second opening of the body so that a part of the annular member is accommodated in the hollow cavity of the body.

A nanoimprint lithography template, method of fabrication, and method of manufacturing an article using the same. The template includes a body having first and second opposed sides, the second side having a mesa extending therefrom, with the mesa having sidewalls and a surface. A recessed shelf extends around a perimeter of the mesa surface, with a light-blocking material positioned on at least the recessed shelf and at a thickness such that the light-blocking material does not extend beyond a plane defined by the mesa surface.

The present invention relates to a new method of synthesizing two-dimensional polyaniline (PANI) nanosheets using ice as a removable hard template. The method comprises polymerizing aniline on an ice surface. The synthesized PANI nanosheets show distinctly high current flows of 5.5 mA at 1 V and a high electrical conductivity of 35 S/cm, which mark a significant improvement over previous values on other PANIs reported over the past decades. These improved electrical properties of the PANI nanosheets are attributed to the long-range ordered edge-on n-stacking of the quinoid ring, ascribed to the ice surface-assisted vertical growth of PANI. The PANI nanosheet can be easily transferred onto various types of substrates via float-off from the ice surfaces. In addition, PANI can be patterned into any shape using predetermined masks, and this is expected to facilitate the eventual convenient and inexpensive application of conducting polymers in versatile electronic device forms.

A water-soluble insert for use in joining pipes, made of a material comprising a salt selected from the group consisting of KCl, Na Cl, and mixtures thereof; and MgO. Upon addition of a small amount of water to the material, the MgO reacts with hygroscopic impurities in the chloride salt to provide a material with superior properties. The insert is cast from the material, in general by being placed on a form and compressed. Also disclosed is the use of the insert in joining the ends of two pipes, especially pipes made from thermoplastic. The insert is placed in the matching pipe ends, which are then welded. After the join is complete, water is flowed through the pipe, dissolving the insert.

A method of forming an implant includes providing a preformed shell formed from at least one cured elastomeric layer. The preformed shell includes an outer surface, an inner surface, and an opening for accessing an interior volume of the preformed shell. The method further includes expanding the preformed shell to an expanded state, in which the interior volume is greater than the interior volume of the preformed shell at a time of forming the preformed shell and forming an inner zone having at least one inner elastomeric layer on at least a portion of the inner surface of the preformed shell, while the shell is in the expanded state, thereby forming a multi-zone shell. The method further includes reducing the interior volume of the multi-zone shell, thereby contracting the at least one inner elastomeric layer of the inner zone and causing texturing of the at least one inner elastomeric layer.

A method of manufacturing a core for a production process and to a core manufactured in accordance with the method are provided. The method includes providing a mold containing a soluble substance and one or more fibers and causing the soluble substance to solidify around the one or more fibers.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

A method of forming a fluid-filled implant is provided. The method includes: forming a first zone of an elastomeric membrane defining at least one partially enclosed void space; expanding a volume of the void space, thereby expanding a volume enclosed by the first zone; forming a second zone comprising at least one elastomeric middle layer on at least a portion of the expanded first zone; and reducing the volume of the void space, thereby contracting elastomeric layers of the first zone and the second zone. The method also includes forming an adjustable implant from the elastomeric membrane by enclosing the void space to form at least one chamber.
