摘要:
A process for preparing a catalyst comprising palladium supported on a carrier via a layered precursor, comprising the following steps: (1) synthesis of hydrotalcite layered precursor which comprises promoting metal element and aluminium on the surface of the carrier of Al2O3 microspheres, the atoms of the promoting metal and aluminium being highly dispersed by each other and bonded firmly to the carrier due to the crystal lattice positioning effect of the hydrotalcite crystal; (2) introduction of palladium into the carrier through impregnation; (3) drying; and (4) calcination and reduction with H2, the hydrotalcite layered precursor being converted into a composite oxide which consists of oxides of the promoting metal and aluminium, and the promoting metal element and aluminium being highly dispersed by each other and being able to separate and disperse the mainly active palladium element loaded later. The process has the advantages of improving the catalytic performance of the catalyst, enhancing the stability of the catalyst, and achieving the object of reducing the consumption of the precious metal-palladium.
摘要:
A datacommunications patching system includes: a mounting frame; a first module mounted in the mounting frame and including a plurality of connector ports on one side thereof and first and second connectors on another side thereof; and a backplane that is mounted in the mounting frame. The backplane electrically connects to the first module via the first connector when the first module is mounted in the mounting frame in a first orientation, and wherein the backplane electrically connects to the first module via the second connector when the first module is mounted in the mounting frame in a second orientation that is inverted from the first orientation.

Provided is an extracellular domain of a mammalian Fat1 (Fat1EC). Also provided is an intracellular domain of a mammalian Fat1 (Fat1IC). Additionally provided is a vector comprising a nucleic acid sequence encoding the Fat1EC. A vector comprising a nucleic acid sequence encoding the Fat1IC is further provided. Also, a vascular stent coated with the Fat1EC is provided. Further provided is a vascular stent coated with a Fat1 ligand that activates Fat1. A method of treating a patient at risk for restenosis of a blood vessel is additionally provided. Further, methods of treating an injured blood vessel in a patient is provided. A method of treating a patient at risk for restenosis of a blood vessel or having an injured blood vessel is also provided.
