A solid oxide fuel cell device incorporates a sealing material resistant to hydrogen gas permeation at a sealing temperature in the intermediate temperature range of 600.degree. C. 800.degree. C., the seal having a CTE in the 100.times.10.sup.-7/.degree. C. to 120.times.10.sup.-7/.degree. C., wherein the sealing material comprises in weight %, of: (i) a 80 to 95 wt % of glass frit, the glass frit itself having a composition in mole percent of: SiO.sub.2 70 85%; Al.sub.2O.sub.3 0 5%; Na.sub.2O.su...
Materials conveying equipment 10 includes a support structure 12. A housing 20 is mounted on the support structure 12, the housing 20 having an inlet opening 26 and a remote discharge opening. A shaftless screw conveyor 18 is arranged rotatably in the housing 20 for conveying materials from the inlet opening 26 of the housing 20 to the discharge opening of the housing 20. A gravimetric unit 16 is mounted at the discharge opening for receiving the materials.
A friction material comprising a filler, a binder, and a lubricant, wherein a part or the whole of the filler is constituted by molybdenum trioxide. Not only is the friction material improved in anti-cracking property and anti-fading property under high-temperature and high-load conditions, but the friction material can be prevented from deterioration due to ashing.
An imaging material is provided in the form of a photothermographic or thermographic image forming layer containing an organic silver salt on one surface of a support and further comprising a polyvalent metal ion and a phthalic acid compound on the image forming layer-bearing surface of the support. The imaging material has improved shelf stability before and after image formation and the ease of handling and produces high-quality blue black tone images.
A substantially complete coating of a zeolite onto a material such as catalyst particles can be achieved by treating the material prior to or simultaneously with zeolite formation, with a polyelectrolye. Copper catalyst systems show good hydrogen storage while blocking access of hydrocarbons to the catalyst.
The invention provides a synthetic bone precursor material comprising amorphous calcium phosphate and a constituent that inhibits the crystallisation of calcium hydroxyapatite to amorphous calcium phosphate. The synthetic bone precursor may comprise a material of formula CaxMgyPO4 wherein Mg acts as an inhibitor for crystallisation. Other crystallisation inhibitors such as pyrophosphate may be present. The inhibitor is capable of dissolving in physiological saline. Loss of inhibitor from the pre...
Programmable material is a collection of substantially cubic shaped bricks called monomers that move relative to each other under computer control to sculpt engineering structures (5) and mechanisms (6) (walking machine) illustrated in FIG. 2. The monomers have features to lock to other monomers and slide relative to other monomers without separating. The monomers are fault tolerant against damage; functional monomers move faulty monomers and replace them with functioning clones. Movement of mon...
This invention relates generally to new luminescent materials. Specifically, this invention relates to the discovery of phosphor materials in the forms of A.sub.2 BX.sub.4, ABX.sub.4-y :M and A.sub.3-z B.sub.5 X.sub.12 :M.sub.z. More specifically, this invention relates to the discovery of phosphor materials having compositions of matter in the forms, Sr.sub.2 CeO.sub.4, (Y.sub.0.82 Al.sub.0.07 La.sub.0.06)VO.sub.4 :Eu.sub.0.05 and (Y.sub.0.5 Gd.sub.0.5).sub.2.97 (Al.sub.0.5 Gd.sub.0.5).sub.5 O....
The use of 3-methyl-5-cyclohexylpentanol, 3-methyl-5-cyclohexylpentanal or mixtures thereof as fragrance materials is disclosed. The subject materials possess unique fragrance notes and are advantageous in that they are cost-effective.
A composite material is described which is characterized by a substrate based on glass fibers, mineral fibers or derived timber products and by a nanocomposite which is in functional contact with said substrate and is obtainable by surface modification of a) colloidal inorganic particles with b) one or more silanes of the general formula (I) where the radicals A are identical or different and are hydroxyl groups or groups which can be removed hydrolytically, except methoxy, the radicals R are id...
