An analytical test device useful for example in pregnancy testing, comprises a hollow casing (500) constructed of moisture-impervious solid material, such as plastics materials, containing a dry porous carrier (510) which communicates indirectly with the exterior of the casing via a bibulous sample receiving member (506) which protrudes from the casing such that a liquid test sample can be applied to the receiving member and permeate therefrom to the porous carrier, the carrier containing in a first zone a labelled specific binding reagent is freely mobile within the porous carrier when in the moist state, and in a second zone spatially distinct from the first zone unlabelled specific binding reagent for the same analyte which unlabelled reagent is permanently immobilised on the carrier material and is therefore not mobile in the moist state, the two zones being arranged such that liquid sample applied to the porous carrier can permeate via the first zone into the second zone, and the device incorporating means, such as an aperture (508) in the casing, enabling the extent (if any) to which the labelled reagent becomes bound in the second zone to be observed. Preferably the device includes a removable cap for the protruding bibulous member.

Capsules and similar objects are made from materials having diamond (sp³) lattice structures, including diamond materials in synthetic crystalline, polycrystalline (ordered or disordered), nanocrystalline and amorphous forms. The capsules generally include a hollow shell made of a diamond material that defines an interior region that may be empty or that may contain a fluid or solid material. Some of the capsules include access ports that can be used to fill the capsule with a fluid. Capsules and similar structures can be manufactured by growing diamond on suitably shaped substrates. In some of these methods, diamond shell sections are grown on substrates, then joined together. In other methods, a nearly complete diamond shell is grown around a form substrate, and the substrate can be removed through a relatively small opening in the shell.

Buckyrock is a three-dimensional, solid block material comprising an entangled network of single-wall carbon nanotubes (SWNT), wherein the block comprises greater than 75 wt % SWNT. SWNT buckyrock is mechanically strong, tough and impact resistant. The single-wall carbon nanotubes in buckyrock form are present in a random network of individual single-wall carbon nanotubes, SWNT “ropes” and combinations thereof. The random network of the SWNT or SWNT ropes can be held in place by non-covalent “cross-links” between the nanotubes at nanotube contact points. In one embodiment, SWNT buckyrock is made by forming a SWNT-water slurry, slowly removing water from the slurry which results in a SWNT-water paste, and allowing the paste to dry very slowly, such that the SWNT network of the SWNT-water paste is preserved during solvent evaporation. Buckyrock can be used in applications, such as ballistic protection systems, involving light-weight material with mechanical strength, toughness and impact resistance.

A surgical clamp includes opposing jaws and a covering enhancing traction between the jaws and a body conduit. A multiplicity of fibers oriented to extend longitudinally between the clamp and conduit may be composed of filaments and either woven or non-woven to form a fabric.

The nature of the weave can control characteristics such as smoothness, absorption, and texture. The fibers or filaments may be formed from any solid or semi-solid material, adding its own characteristics to the resulting fabric insert or clamp.

A method and apparatus for embedding features and controlling material composition in a three-dimensional structure (130) is disclosed. The invention enables the control of material characteristics, within a structure (130) made from a plurality of materials, directly from computer renderings of solid models of the components. The method uses stereolithography and solid model computer file formats to control a multi-axis head (480) in a directed material deposition process (123). Material feedstock (126, 127) is deposited onto a pre-heated substrate (19). Depositions (15) in a layer-by-layer pattern, defined by solid models (141, 146), create a three-dimensional article having complex geometric details. Thermal management of finished solid articles (250-302), not available through conventional processing techniques, is enabled by embedded voids (152) and/or composite materials (126, 127), which include dissimilar metals (210, 216). Finished articles control pressure drop and produce uniform coolant flow and pressure characteristics. High-efficiency heat transfer is engineered within a solid structure by incorporating other solid materials with diverse indexes. Embedding multi-material structures (132, 134) within a normally solid component (141) produces articles with diverse mechanical properties. Laser and powder delivery systems (420, 170) are integrated in a multi-axis deposition head (480) having a focused particle beam (502) to reduce material waste.

In a method for forming a wiring of a semiconductor device using an atomic layer deposition, an insulating interlayer is formed on a substrate. Tantalum amine derivatives represented by a chemical formula Ta(NR₁)(NR₂R₃)₃ in which R₁, R₂ and R₃ represent H or C₁-C₆ alkyl group are introduced onto the insulating interlayer. A portion of the tantalum amine derivatives is chemisorbed on the insulating interlayer.

A ligand in the tantalum amine derivatives chemisorbed on the insulating interlayer is removed from the tantalum amine derivatives by a chemical reaction between the reacting gas and the ligand to form a solid material including tantalum nitride. The solid material is accumulated on the insulating interlayer through repeating the above processes to form a wiring.
