Abstract: The inventors of the instant invention have realized that blocking the thermal flow from a cooking vessel to the surface of the cooking area can provide power savings up to 4% according to energy measurements. According to embodiments of the invention, spacers (110, . . . , 120; 310, . . . , 370; 220; 410) are provided between the surface of a cooking area (105, 210, 380, . . . , 395) and a cooking vessel such as a cooking pot or a kettle. The spacers may be integrated in form of a curvature in a glass ceramic surface of a hob or may be placed at top of a cooking area (100). Another solution may be provided in the cooking vessel (400) such as a kettle that has an isolating lowest bottom in form of integrated spacers which can directly be placed on common induction hobs.

Abstract: Systems and methods are provided for detecting or measuring binding affinity between different compositions. The methods include contacting one or more magnetic beads having a surface including a first composition with a substrate having a surface including a second composition; applying a rotating magnetic field to the one or more magnetic beads effective to cause the one or more magnetic beads to move across the surface of the substrate; measuring the movement of the one or more magnetic beads across the substrate surface to determine a translational velocity; and determining a binding affinity between the first and second compositions from the translational velocity.

Abstract: The present invention is directed to the synthesis of novel delaminated layered zeolite precursor materials prepared by fluoride/chloride anion-promoted exfoliation. The method comprises, for example, using a combination of fluoride and chloride anions at a mild pH in aqueous solution to affect delamination of a layered zeolite precursor. The method can also comprise using a combination of fluoride and chloride anions in a non-aqueous solution comprising an organic solvent. The method may be used in conjunction with either acidification or sonication, or both. The resulting delaminated zeolite precursors are then isolated. Precursors that are then isolated lack amorphous silica content. The UCB-1 product is an example of such a novel oxide material and is obtained in yields in excess of 90% without the need for sonication.

Abstract: Provided is a surfactant-free, single-step synthesis of delaminated aluminosilicate zeolites. The process comprises the step of heating a borosilicate zeolite precursor in a metal salt solution, e.g., an aluminum nitrate solution, zinc nitrate solution or manganese nitrate solution. The delaminated aluminosilicate zeolite product is then recovered from the solution.

Abstract: Provided is an organic ligand-bound metal surface that selects one gaseous species over another. The species can be closely sized molecular species having less than 1 Angstrom difference in kinetic diameter. In one embodiment, the species comprise carbon monoxide and ethylene. Such organic ligand-bound metal surfaces can be successfully used in gas phase separations or purifications, sensing, and in catalysis.

Abstract: A cooling arrangement adapted to be used in a process of preparing a fine powder, and a method for using same are described. The cooling arrangement (100) comprises: a solid particles feed ingress means, a solid particles mixing means (140), a plurality of cooling air discharging devices (130) and a solid particles egress means. The cooling arrangement is characterized in that the averaged diameter of the solid particles fed the said solid particles ingress means is essentially less than 6 mm. Preferably, the solid particles are fed to the cooling arrangement and free fall (120) onto the bottom section thereof.

Abstract: The present invention is directed to the activation of metal carbonyl clusters by an oxidative agent to prepare a stable metal cluster catalyst exhibiting catalytic rate enhancement. The activation comprises, for example, using oxygen for decarbonylation of carbonyl ligands and changing the oxidation state of the other ligands. In one aspect, treatment of the metal cluster catalyst under oxidative conditions in a flow reactor leads to removal of CO ligands and oxidation of bound calixarene phosphine ligands, and results in a stable activated open metal cluster that is more active for ethylene hydrogenation catalysis. The resulting metal cluster contains coordinatively unsaturated sites comprising carbonyl vacancies. In one aspect, the resulting activated open metal cluster can be used as a catalyst in a variety of chemical transformations.

Abstract: A separation arrangement is provided for separating between particles of different materials having different densities and comprised in a mixture of fine particles. The arrangement comprises: a solid particles feed ingress means, a solid particles pushing/pulling means and at least one mesh adapted to stop particles of the lighter material. The particles comprised in the mixture are allowed to free fall within the separation arrangement, and particles of the lighter material are being extracted away from the free falling particles by the solid particles pushing/pulling means and conveyed towards the at least one mesh. The particles of the heavier material are allowed to complete their free fall and to reach the lower part of the separation arrangement.

Abstract: The invention provides complexes in which ligands (e.g., calixarene-related compounds) are coordinated to a metal colloid, e.g. a gold colloid. In exemplary embodiments, two or more ligands complexed to the metal colloid are larger than the metal colloid, thus providing an accessible metal center. The complexes can be immobilized on a substrate. The complexes of the invention are useful as tunable and highly robust isolated metal colloids that find use in binding of molecules and catalysis of chemical reactions.
