A mold and a method of manufacturing GOS ceramic scintillator by using the mold are provided. The mold comprises: a female outer sleeve having a cavity disposed inside; a plurality of female blocks disposed inside the cavity, the plurality of female blocks being put together to form a composite structure having a vertical through hole; and a male upper pressing head and a male lower pressing head, wherein each of the male upper pressing head and the male lower pressing head has a shape consistent with that of the vertical through hole. The disclosure may reduce defects of the related art in hot-pressing-sintering such as a mold has a short retirement period and a high material waste, significantly reduce the cost for production of the GOS ceramic scintillator, and significantly improve a process economy.

The invention relates to a method for the production of a shaped body comprising at least the method steps of producing a blank having an open porosity by pressing and treating pourable material in a first heat treatment step comprising or consisting of a metal oxide, infiltrating the blank with an infiltration fluid containing a precursor of the metal oxide, precipitating hydroxide of the metal from the infiltration fluid by treating the blank with a basic solution, forming the metal oxide from the hydroxide by treating the blank in a second heat treatment step, wherein the blank is processed before or after the second heat treatment step to achieve a shape that corresponds to the shaped body.

Disclosed is a manufacturing method of a gas sensor element. The gas sensor element has a plate shape extending in a direction of an axis thereof and includes: a detection portion arranged on a front end side of the gas sensor element to detect a specific gas component in a gas under measurement; and a porous protective layer formed around the detection portion. The manufacturing method of the gas sensor element is characterized in that the porous protective layer is formed by press forming of a raw material powder.

Aspects include methods of fabricating antibacterial surfaces for medical implant devices including patterning a photoresist layer on a silicon substrate and etching the silicon to generate a plurality of nanopillars. Aspects also include removing the photoresist layer from the structure and coating the plurality of nanopillars with a biocompatible film. Aspects also include a system for preventing bacterial infection associated with medical implants including a thin silicon film including a plurality of nanopillars.

An automated mold change system, for use with a concrete products machine of a type having a products forming section and a feedbox assembly section, includes a mold exchange assembly coupled to an underside of the feedbox assembly section and vertically moveable therewith, a mold transfer assembly on an opposed side of the products forming section from the feedbox assembly section, and mounts on the products forming section configured to retain a mold assembly thereon. A mold exchange path runs axially between the mold exchange assembly and the mounts on the products forming section and intersects a mold transfer path of the mold transfer assembly at a load-unload position, wherein the mold exchange assembly is configured to lift a mold off of the mounts and onto the mold transfer assembly at the load-unload position.

[Problem] To provide a molded body in which hydraulic lime is used and a method for producing the same.

[Solution] A molded body having a flexural strength of at least 7.5 N/mm.sup.2 and containing hydraulic lime subjected to calcium carbonate crystallization. A method for producing a molded body containing hydraulic lime, comprising (a) a step for press molding a mixture containing hydraulic lime and water at a pressure of at least 5 N/mm.sup.2 and (b) a step for submitting the press-molded body yielded by (a) to carbon dioxide curing.

Particulate compositions including cores, binders, and powders are provided. Also provided are methods for producing particulate compositions, and methods for using particulate compositions.

Provided is a method for preparing a grain boundary insulation-type dielectric. The method includes the steps of obtaining a titanic acid compound and a ferroelectric having a value less than a melting point of the titanic acid compound; obtaining a mixture by adding the ferroelectric material to the titanic acid compound; and sintering the mixture at a temperature equal to or more than a melting point of the ferroelectric material.

Fluoride-based nanocomposite materials, optical articles made therefrom, and methods of making the fluoride-nanocomposite materials and optical articles.
