Abstract: The present application provides a preparation method for a core-shell structured tungsten/gadolinium oxide functional fiber for X and γ ray protection, comprising: first preparing a core-shell structured tungsten/gadolinium oxide powder; preparing a W@Gd2O3/PP blended melt from the powder; and preparing a W@Gd2O3/PP composite fiber from the blended melt. The core-shell structured tungsten/gadolinium oxide functional fiber prepared by the method can play a role in synergistic protection in the aspect of radiation protection, eliminate a weak protection area, and effectively absorb secondary radiation generated by radiation. Secondly, the prepared functional fiber has the characteristics of no lead and light weight, and has good application prospects in the aspect of X and γ ray radiation protection.

Abstract: Methods of reshaping ferrules (20) used in optical fiber cables assemblies (170) are disclosed. The reshaping methods reduce a core-to-ferrule concentricity error (E), which improves coupling efficiency and optical transmission. The methods include measuring a distance (δ) and angular direction (θ) from a true center (30) of the ferrule to the core (46), wherein the true center (30) is based on an outer surface (26) of the ferrule. The methods also include reshaping at least a portion (26P) of the ferrule (20) to define a new true center (30′) of the ferrule (20) and reduce the distance (δ). A variety of reshaping techniques are also disclosed.

Abstract: A method is provided that includes: forming a low-index trench region with a first density; forming an inner barrier layer comprising silica around the trench region at a second density greater than the first density; depositing silica-based soot around the first barrier layer to form an overclad region at a third density less than the second density; inserting a core cane into a trench-overclad structure; forming an outer barrier layer comprising silica in an outer portion of the overclad region at a fourth density greater than the third density; flowing a down dopant-containing gas through the trench-overclad structure to dope the trench region with the down dopant, and wherein the barrier layers mitigate diffusion of the down-dopant into the overclad region; and consolidating the trench-overclad and the core cane.

Abstract: Provided herein are conductive glass-metal compositions, as well as methods of making and using such compositions. In one example, the compositions include gold (Au) doped lithium-borate glasses shown to exhibit a transition from ionic to electronic conduction within the same sample. This is achieved via appropriate heat treatment, and particularly by heat treatment after annealing, wherein the post-annealing heat treatment is performed at temperatures below the glass transition temperature (Tg). The methods described herein are believed to introducing polarons formed from the trapping of electrons at partially ionized gold atoms. This unique electrical response provides new functionality to this class of nanocomposites. Additionally, increased thermal conductivity can be provided to an otherwise low conductive glass composition using the inventive methods and other subject matter provided herein.

Abstract: A method of preparing an organic-inorganic hybrid material is described. A M(OR)x and an organically modified Si-alkoxide having a predetermined functional group are dissolved in a first solvent and a second solvent to form a first solution and a second solution, respectively. The first solution and the second solution are then mixed and heated. As a result, the M(OR)x reacts with the organically modified Si-alkoxide to form a functionalized organic-inorganic hybrid material. Furthermore, the solid content of the functionalized organic-inorganic hybrid material is increased by transferring the same into another solvent. Therefore, a thick hybrid film is fabricated by means of the transferred functionalized organic-inorganic hybrid material.
