摘要:
The invention relates to a process for producing highly porous layers, which comprises making available a substrate having a substrate surface; modifying at least sections of the substrate surface so as to produce surface-modified sections in which anchor groups for metal ions are provided; applying at least one MOF to the surface-modified sections of the substrate so as to produce a layer of the MOF. The invention further relates to a composite comprising a substrate and a porous layer of an MOF located on the substrate.

The invention relates to a process for producing a catalyst comprising a porous support and at least one active metal, which comprises providing a porous support which has a specific BET surface area of at least 500 m2/g and is transparent to an activating radiation, applying at least one active metal precursor which comprises at least one active metal and at least one group which is bound via a ligator atom selected from among oxygen, sulfur, nitrogen, phosphorus and carbon to the active metal atom to the porous support so as to produce an adduct which comprises the porous support and the at least one active metal precursor; and illuminating the adduct with the activating radiation to convert the at least one active metal into its reduced form.
摘要:
A method for controlling or regulating a vacuum valve that includes a valve body (1) with a valve opening (2), a closing member (3), an actuator (5) for moving the closing member (3), and a control device (9) by which the actuator (5) is triggered and by which the pressing force acting on the elastic seal (4) in the closed position of the closing member (3) is set. The setting of the pressing force acting on the elastic seal (4) is performed as a function of at least one parameter that can be input by a user.

A floor cleaning apparatus includes a housing, a suction generator having a motor and a sound cancellation generator. During operation of the apparatus the motor produces a first sound and the sound cancellation generator produces a second sound. The second sound produced by the sound cancellation generator is substantially 180 degrees out of phase with the first sound so that noise generated during operation of the floor cleaning apparatus is reduced.
摘要:
A process for preparing solutions of sulfonated arylphosphines comprising reacting arylphosphines with oleum, diluting the sulfonation mixture with water, extracting the diluted sulfonation mixture with a solution of a water-insoluble organic solvent, reacting the organic phase with a solution of an inorganic base in water, adjusting the resulting aqueous solutin of sulfonated arylphosphines to a pH of up to 3 by addition of an acid, and passing an inert gas stream through the aqueous solution comprising sulfonated arylphosphines until sulfur is no longer liberated from the aqueous solution of sulfonated arylphosphines.
摘要:
The present invention relates generally to functional pathway configurations at the interfaces between integrated circuits (ICs) and the circuit assemblies with which the ICs communicate. More particularly, the present invention relates generally to the functional pathway configuration at the interface between one or more semiconductor integrated circuit dice, including an IC package and the circuitry of a system wherein the integrated circuit dice is a digital signal controller. Even more particularly, the present invention relates to a 18, 28, 40, 44, 64 or 80 pin functional pathway configuration for the interface between the digital signal controller and the system in which it is embedded.
摘要:
The present invention relates to a process in which a triglyceride is transesterified with an alcohol in the presence of a solid catalyst. In order to provide a process by means of which a triglyceride can be transesterified with an alcohol in the presence of a solid catalyst in relatively moderate reaction conditions with a good yield and at relatively high reaction rate, it is proposed that the solid catalyst comprises a zeolite X with an Si/Al atomic ratio of less than 1.2.

The invention relates to a process for preparing a catalyst for the desulfurization of hydrocarbon streams, which comprises the steps: (a) preparation of an aqueous suspension comprising: a thermally decomposable copper source, a thermally decomposable molybdenum source, and a solid zinc source; (b) heating of the suspension to a temperature at which the thermally decomposable copper source and the thermally decomposable molybdenum source decompose so that a suspension of a precipitate comprising zinc compounds, copper compounds and molybdenum compounds is obtained; (c) cooling of the suspension obtained in step (b); (d) separation of the precipitate from the suspension; (e) drying of the precipitate. The invention further relates to a catalyst which can be obtained by the process of the invention and also to its use for the desulfurization of hydrocarbon streams.
摘要:
An upright vacuum cleaner includes a nozzle assembly and a canister assembly pivotally connected to the nozzle assembly. The nozzle assembly includes a suction inlet. The canister assembly includes a first housing member and a removable cover that cooperate together to form a wand receiver, a hose connector and an integral air path between the wand receiver and the hose connector.
