摘要:
A method of preparing M-N-C catalysts utilizing a sacrificial support approach and inexpensive and readily available polymer precursors as the source of nitrogen and carbon is disclosed. Exemplary polymer precursors include those that do not form complexes with iron, but which do complex with silica, for example, polyetheleneimine (PEI), Poly(2-ethyl-2-oxazoline), Poly(acrylamide-co-diallyldimethylammonium chloride), Poly(melamine-co-formaldehyde), Poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-s-triazine-2,4-diyl]-[(2,2,6,6-tetramethyl-4-piperidyl)imino]-hexamethylene-[(2,2,6,6-tetramethyl-4-piperidyl)imino] and the like.
摘要:
A method for displaying objects in a CAD system, and corresponding CAD system and computer program product. The method includes loading a graphic model with a plurality of model elements including edges and faces in a CAD system and receiving a selection of a display technique to be used on the graphic model. The method also includes classifying each model element as important or unimportant. The method also includes hiding a first subset of the unimportant model elements according to the selected display technique and adjusting the transparency of a second subset of the unimportant model elements according to the selected display technique, so that the important model elements are clearly visible with relation to the unimportant model elements. The method can produce a simplified graphic model that is displayed by the CAD system.
摘要:
A development environment, comprising: text editing means (810); an interface (860) for passing amended code to a live running application (880) on a Java EE platform, and for receiving an exception in the event that said exception is generated by the application; means (830) for parsing said received exception in order to identify an associated portion of the amended code as identified in the exception; and means (810) for identifying the associated line of the class within the text editing means (810).
