摘要:
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 a non-aqueous solution to affect delamination of a layered zeolite precursor, generally 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.

A heating furnace (2) heats a workpiece to be plated. An ingot preheating furnace (8) encloses an ingot carrying device (7) that carries ingots (6) to a place near a melting furnace (3) that melts the ingots (6) of a plating material, contains the molten plating material in which a workpiece to be plated is immersed. The ingot preheating furnace (8) preheats the ingots (6) supported by the ingot carrying device (7) at a temperature below the melting point of the ingots (6) by an exhaust gas (G) discharged from the heating furnace (2).

摘要:
In the conversion of chemical energy into electric energy by the electrochemical reaction of a gaseous anodic reactant and a gaseous cathodic reactant through the medium of a heteropoly acid solid electrolyte, the life of the solid electrolyte is notably increased by passing each reactant through pools of a saturated aqueous solution of a specific salt bordering on closed empty spaces thereby allowing the reactants to acquire prescribed humidities prior to the contact thereof with the anode and cathode.

Disclosed is a proton permselective solid-state member which is formed of a heteropoly acid represented by the generic formula, H.sub.m [X.sub.x.sup.. Y.sub.y.sup.. O.sub.z ].sup.. nH.sub.2 O, or a salt thereof. Said permselective member can be used as an electrolyte in the fuel cell and as a permselective membrane in the hydrogen gas refining system.
摘要:
A zeolite material is provided having non-boron heteroatoms on the external surface of the zeolitic material lattice framework and B heteroatoms, or silanols created from boron hydrolysis, throughout the remainder of the lattice framework. The lattice framework of the zeolite material comprises large pore 12 member ring or larger openings at the external surface of the framework, and 10 member ring or smaller openings beneath the external surface large pore openings. Also provided is a process for preparing the zeolitic material.

The humidity of a gas is adjusted by passing the gas through a plurality of compartments containing the saturated aqueous solution of a salt thereby imparting a prescribed value of humidity to the gas.
摘要:
The humidity of a gas is adjusted by passing the gas through a plurality of compartments or chambers within a closed container containing the saturated aqueous solution of a salt thereby imparting a prescribed value of humidity to the gas. A plurality of partition walls are disposed at fixed intervals within the closed container defining a plurality of chambers having upper and lower interior portions and having openings formed therein alternately open into the upper and lower portions of the chambers.
