A method to manufacture reticulated metal foam includes coating a precursor in a molten wax to increase ligament thickness; and investment coating the molten wax coated precursor with a ceramic plaster.

Provided herein are novel tools and methods for the formation of vessels having sculpted interior and exterior forms. Novel high-temperature non-woven textile forms may be used to create a glass vessel having a three-dimensional sculpted interior of almost any shape. The non-woven textile forms may also be used as molds to artfully sculpt bottle exteriors. The invention allows for unprecedented control over the form of glass objects in an industrially scalable process.

A method for manufacturing a turbine engine blade (25) comprising a pressure side and a suction side separated from one another by an inner space for the circulation of cooling air, the blade (25) comprising a tip (S) with a closing wall (29) joining the pressure side and suction side walls in the region of this tip (S) in order to define a well shape, the closing wall including through-holes. The closing wall (29) obtained by moulding has a considerable nominal thickness with pits (36, 37) locally reducing this thickness at each through-hole in order to facilitate the removal by chemical etching of alumina rods defining the holes. Since the closing wall (29) thus has a large nominal thickness, it can then be machined in order to form raised patterns or complex shapes inside the well.

Provided are a cancer cell-trapping metal filter which has a high opening ratio, a cancer cell-trapping metal filter sheet, a cancer cell-trapping device using the cancer cell-trapping filter, and manufacturing methods therefor.

According to a cancer cell-trapping metal filter 1, openings of connected through-holes 12 that are formed in a metal sheet 11 have a wave shape, and thus it is possible to extract a CTC from other components by utilizing a hole diameter on a short-side side of the openings, and it is possible to make the connected through-holes be closer to each other due to the wave shape while maintaining a CTC trapping ability. Accordingly, it is possible to further improve the opening ratio in the cancer cell-trapping metal filter 1.

The present disclosure generally relates to casting molds including a casting core comprising a first metal component and a second metal component. In an aspect, the first metal component has a lower melting point than the second metal component. In another aspect, the second metal component surrounds at least a portion of the first metal component and defines a cavity in the casting core when the first metal component is removed and the second metal component is not removed.

Methods, structures, devices and systems are disclosed for fabricating and implementing nanoparticles with hollow core and sealable holes. In one aspect, a nanoparticle device can includes a shell structure including at least two layers including an internal layer and an external layer, the internal layer structured to enclose a hollow interior region and include one or more holes penetrating the internal layer, the external layer is of a porous material and formed around the internal layer and sealing the one or more holes, and a substance contained within the hollow interior region, the substance incapable of passing through the external layer.

Aspects of the disclosure generally relate to a casting mold for forming a cast part. The casting mold includes a casting shell having an internal surface bounding an interior, and a casting core positioned within the interior to define a cavity between the casting core and the casting shell, whereby the internal surface of the casting shell defines an outer surface of the cast part.

The invention provides a device (200, 300, 400) for heating a continuous flow fluid. Said device (200, 300, 400) consists of a steel conduit (3, 3′, 3″) through which the fluid to be heated flows and of at least one sheathed resistor (2, 2c, 2d, 2e, 2f) that is parallel to the steel conduit (3, 3′, 3″) and that is in thermal contact therewith. The steel conduit (3, 3′, 3″) and the at least one heating element (2, 2c, 2d, 2e, 2f) are incorporated in a die-casting element made of an aluminium alloy.

A stack molding pattern and a shell for manufacturing aircraft turbine engine blades via lost wax casting. The stack molding shell includes a plurality of shell blade elements, each intended for producing a blade, wire elements being arranged within the shell blade elements; and a metal feeder including a plurality of metal outlets, each one radially open towards one of the shell blade elements and connected with the second end portion of the element. The shell includes a protective screen, associated with each second end portion and intended to protect a sensitive portion of the wire elements against the direct impact of a flow of metal from the feeder. The sensitive portion is located in the second end portion, downstream from the protective screen.
