20080221328 | LUMINESCENT LANTHANIDE COMPLEXES - Neutral lanthanide(III) complexes including at least one ligand are disclosed. The ligand includes a heterocyclic aromatic ring with at least one carboxylic acid group attached thereto, wherein a heteroatom of the heterocyclic ring and the carboxylate function of the carboxylic acid group co-ordinate (chelate) to the lanthanide. The complexes can be used in luminescent lamps and luminescent displays. The complexes can be synthesized by heating a mixture of a lanthanide 3+ salt and ligand L in a suitable solvent until a precipitate of the lanthanide complex forms. In one embodiment, the formal 3+ charge on the lanthanide is neutralized by providing in the ligands for the complex, three coordinating carboxylate groups, (RCO | 09-11-2008 |

20080298894 | Wave Protection Structure, Method For Producing A Toe Element For A Wave Protection Structure, And Method For Producing A Wave Protection Structure - A wave protection structure is intended for a slope, such as the slope of a breakwater or a bank, which slope merges into a bed at the location of a toe. The wave protection structure comprises wave protection elements and toe elements. The wave protection elements are each provided with a plurality of projections for engaging in one another and are provided on the slope in a substantially regular imaginary grid, with a horizontal grid spacing between the centres of gravity of the wave protection elements. The toe elements extend along the toe and their shape differs from the shape of the wave protection elements. The centres of gravity of the toe elements are provided at substantially the horizontal grid spacing from one another. As a result of the toe elements being provided at the grid spacing of the wave protection elements, it is easier to position the toe elements. This also allows the use of larger blocks and means that it is no longer necessary to stack the wave protection elements. | 12-04-2008 |

20080293957 | Process for Preparing Organically Modified Layered Double Hydroxide - The invention relates to a process for preparing an organically modified layered double hydroxide having a distance between the individual layers of the layered double hydroxide of above 1.5 nm and comprising an organic anion as charge-balancing anion, the process comprising the steps of: (a) preparing a precursor suspension comprising a divalent metal ion source and a trivalent metal ion source; (b) solvothermally treating the precursor suspension to obtain the layered double hydroxide, wherein an organic anion is added before or during the formation of the layered double hydroxide of step (b), or following the formation of the layered double hydroxide, so as to obtain the organically modified layered double hydroxide, with the proviso that deoxycholic acid is not the sole organic anion. The invention further pertains to a process for preparing an organically modified layered double hydroxide having a distance between the individual layers of the layered double hydroxide of above 1.5 nm and comprising an organic anion as charge-balancing anion, the process comprising the steps of: (a) preparing a precursor suspension comprising a divalent metal ion source and a trivalent metal ion source; (b) thermally treating the precursor suspension to obtain the layered double hydroxide, wherein an organic anion is added before or during the formation of the layered double hydroxide of step (b), or following the formation of the layered double hydroxide, so as to obtain the organically modified layered double hydroxide, with the proviso that in step a) the trivalent metal ion source is not reacted with the organic anion at a temperature of between 60 and 85° C. for 4 to 8 hours prior to the addition of the divalent metal ion source and step b) is subsequently carried out at a temperature of 90 to 95° C. for 4 to 8 hours. | 11-27-2008 |
20100029822 | PROCESS FOR PREPARING LAYERED DOUBLE HYDROXIDE COMPRISING CARBONATE - The invention relates to a process for the production of a layered double hydroxide comprising carbonate by preparing a divalent and trivalent metal ion source-containing slurry, which is subsequently treated solvothermally. If the slurry does not contain a divalent metal ion source containing carbonate, a carbonate source is added during or after the solvothermal treatment. | 02-04-2010 |
20110000632 | Process to Make a Clay Comprising Charge-Balancing Organic Ions, Clays Thus Obtained, and Nanocomposite Materials Comprising the Same - The invention relates to a layered double hydroxide comprising a charge-balancing organic anion, wherein the charge-balancing anion is a monovalent anion comprising at least one hydroxyl group, and which comprises less than 20 wt % boehmite. Claimed are also an aqueous slurry, a water borne coating, a composite material and a master batch comprising the said layered double hydroxide as well as the use of the said layered double hydroxide in paper making processes and as stain blocking agent in water borne coating applications. | 01-06-2011 |
20110139714 | PROCESS FOR REDUCING BULKING SLUDGE IN ACTIVATED SLUDGE WASTEWATER TREATMENT - The present invention pertains to a process for reducing the bulking sludge in an activated sludge plant for wastewater treatment wherein an iron(ll) or iron(lll) salt and at least one fatty amine or fatty amine derivative are used, and to compositions comprising the iron(ll) or iron(lll) salt and one or more fatty amines and/or fatty amine derivatives. | 06-16-2011 |
