Abstract: A cross-linking moiety having a general formula I: ArF-W, wherein ArF comprises a fluorinated phenyl azide group having at least one non-fluorine substituent that is bulkier than fluorine at a meta position relative to the azide group, and W comprises an electron-withdrawing group.

Abstract: The invention relates to a method for producing a metal nanoparticle dispersion, in particular a silver nanoparticle dispersion, wherein after the production of nanoscale metal particles, stabilized by means of at least one auxiliary dispersing agent containing at least one free carboxylic acid group or salt thereof as a functional group, in at least one liquid dispersant (solvent), flocculation of the metal nanoparticles is deliberately caused, the formed metal nanoparticle flocculation is dispersed again in at least one liquid dispersant, optionally by adding a base, and the metal nanoparticle dispersion is set to a desired metal nanoparticle concentration. The invention further relates to a metal nanoparticle dispersion, in particular a silver nanoparticle dispersion, in particular produced by means of the method according to the invention, and to the use of said metal nanoparticle dispersion.

Abstract: A cross-linking moiety having a general formula I: N3—ArF—W, wherein ArF comprises a fluorinated phenyl azide group having at least one non-fluorine substituent that is bulkier than fluorine at a meta position relative to the azide group, and W comprises an electron-withdrawing group.

Abstract: The invention is an improved clip for holding workpieces to racks during alodining, anodizing and/or painting operations. The clip is constructed of a torsion spring having a central coiled portion and laterally extending tines interconnected by the coil. The coil is biased so that the ends of the tines are normally forced toward each other for gripping a workpiece inbetween their ends. A handle is connected to the coil and extends laterally away therefrom. This may be rotated in a manner so as to oppose the coil's bias, thus causing the tines' ends to spread apart for releasing the workpiece.
