摘要:
Selected olefins such as ethylene and &agr;-olefins are polymerized by nickel [II] complexes of certain monoanionic ligands. The polyolefins are useful in many applications such as molding resins, film, fibers and others. Also described are many novel nickel compounds and their precursors, as well a novel ligands.
摘要:
Olefins containing selected functional groups such as silyl, ether and alkenyl, and often containing a blocking group, may be copolymerized with unsubstituted olefins such as ethylene and propylene in the presence of certain coordination compounds of nickel or palladium. The resulting polymers are useful as molding resins, elastomers, in adhesives and for films.
摘要:
Novel reactions used to prepare phosphole and bisphosphole compounds are detailed. Novel phosphole compounds and metal coordination compounds of phosphole and bisphosphole compounds are also provided. These metal coordination compounds are useful as catalysts for the polymerization or olefins with carbon monoxide and for the polymerization of acrylic monomers.

An absorbent material that comprises a water-insoluble, water-swellable absorbent polymer. The absorbent material comprises a reactive polyether chemically bonded to the absorbent polymer whereby the contact angle of blood on a surface of the absorbent material attains from about 0 degree to about 40 degree. Because of the improved wettability with liquids, the absorbent material can provide higher absorbent characteristics with liquids, in particular with blood.

A digital predistortion processing method and device, the method comprises: performing digital predistortion processing on a baseband signal according to a first predistortion correction parameter, converting the baseband signal after digital predistortion processing into a radio-frequency signal, dividing the radio-frequency signal, and respectively outputting each path of radio-frequency signal to a distinct power amplifier; and, coupling and outputting the radio-frequency signal output by each power amplifier to a feedback link for combination to obtain a combined signal, and performing conversion processing on the combined signal; and generating a predistortion correction parameter according to the combined signal after conversion processing and the baseband signal before digital predistortion processing, and updating the first predistortion correction parameter to a second predistortion correction parameter.
摘要:
The present invention discloses an integrated analysis device for simultaneously detecting exhaled breath condensates (EBCs) and volatile organic compounds (VOCs) in human exhaled breath. The device comprises a module for sampling, separating and enriching a detected object, an EBCs detection module and a combined VOCs detection module. The module for sampling, separating and enriching a detected object is connected with the EBCs detection module via a syringe pump for sample injection. The module for sampling, separating and enriching a detected object is connected with the combined VOCs detection module by a capillary separation column. In the present invention, it is achieved that EBCs and VOCs in human exhaled breath are simultaneously sampled, separated and condensed; the heavy metal ions, cell factors, etc. in the collected EBCs are detected with a light addressable potentiometric sensor (LAPS); the condensed VOCs can be quantitatively detected by the combined VOCs detection module with a high sensitivity; and a heating rod and a platinum resistor can be conveniently replaced because a separated outlet heating piece is designed in the combined VOCs detection module.
