A grilling belt includes a flexible support having first and second major surfaces, an extruded fluoropolymer layer overlying the first major surface, and a cast or skived fluoropolymer layer overlying the extruded fluoropolymer layer. Another grilling belt can include a support having first and second major surfaces, and a first fluoropolymer film overlying the first major surface. The support can include a first fabric having a first bias angle, and a second fabric laminated to the first fabric and having a second bias angle different from the first bias angle by between 20&#xb0; and 160&#xb0;.

A scintillation device includes a ceramic scintillator body that includes a polycrystalline ceramic scintillating material comprising gadolinium. The polycrystalline ceramic scintillating material is characterized by a pyrochlore crystallographic structure. A method of producing a ceramic scintillator body includes preparing a precursor solution including a rare earth element precursor, a hafnium precursor, and an activator (Ac) precursor. The method also includes obtaining a precipitate from the solution and calcining the precipitate to produce a polycrystalline ceramic scintillating material including the rare earth element, hafnium, and the activator, and having a pyrochlore titrating the precursor solution into the precipitant solution structure.

Ceramic scintillator body and scintillation device

A ceramic scintillator body includes a polycrystalline ceramic scintillating material having a substantially cubic crystallographic structure. The polycrystalline ceramic scintillating material has a chemical composition represented by a general formula LUGdO:Ac, where x is greater than zero and less than two, and where Ac is an activator.

A coated fabric includes a reinforcement, a first coating disposed on the reinforcement, and a second coating disposed on the first coating. The first coating includes perfluoropolymer. The second coating includes perfluoropolymer and a silicone polymer in an amount in a range of 2 wt % to 30 wt %.

A polycrystalline ceramic scintillator body includes a ceramic scintillating material comprising an oxide of gadolinium (Gd) and a second rare earth element (Re). The ceramic scintillating material has a composition, expressed in terms of molar percentage of oxide constituents, that includes greater than fifty-five percent (55%) GdOand a minority percentage Of ReO. The ceramic scintillating material includes an activator.

A scintillation device includes a free-standing ceramic scintillator body that includes a polycrystalline ceramic scintillating material comprising a rare earth element, wherein the polycrystalline ceramic scintillating material is characterized substantially by a cation-deficient perovskite structure. A method of producing a free-standing ceramic scintillator body includes preparing a precursor solution including a rare earth element precursor, a hafnium precursor and an activator (Ac) precursor, obtaining a precipitate from the solution, and calcining the precipitate to obtain a polycrystalline ceramic scintillating material including a rare earth hafnate doped with the activator and having a cation-deficient perovskite structure.

The disclosure is directed to a barrier structure including a fluoropolymer layer, a polymeric layer, and an adhesive layer. The barrier structure has a chemical permeation breakthrough detection time greater than about one hour for hazardous chemicals as measured by ASTM F739. The disclosure is further directed to a method of forming the aforementioned barrier structure. The barrier material is designed to be suitable for construction of shelters, clothing, containers and other articles requiring barrier properties.

Algae-resistant roofing shingles are formed by extruding a mixture of mineral particles and a binder to form porous granule bodies, and algaecide is distributed in the pores to provide alqae-resistant granules, which are subsequently applied to roofing shingles. Release of the algaecide is controlled by the structure of the granules.

A radiation detection system can include a scintillating member including a polymer matrix, a first scintillating material, and a second scintillating material different from the first scintillating material and at least one photosensor coupled to the scintillating member. The radiation detection system can be configured to receive particular radiation at the scintillating member, generate a first light from the first scintillating material and a second light from the second scintillating material in response to receiving the particular radiation, receive the first and second lights at the at least one photosensor, generate a signal at the photosensor, and determine a total effective energy of the particular radiation based at least in part on the signal. Practical applications of the radiation detection system can include identifying a particular isotope present within an object, identifying a particular type of radiation emitted by the object, or locating a source of radiation within the object.

A microabrasive tool is formed from a slurry including liquid, abrasive grains, a bonding material, and a polymer&#x2014;for example, gellan gum. The slurry is cast in a mold, and the polymer is ionically cross-linked. Cross-linking the polymer fixes the structure of the bonding material and the abrasive grains, wherein the abrasive grains are dispersed substantially uniformly within the bonding material. The ionically cross-linked structure of bonding material and abrasive grains can then be fired to form a microabrasive tool.
