ChemInform Abstract: Sexterrylenetetracarboxylic Bisimides: NIR Dyes.

Abstract

Bisamide (I) is prepared by Suzuki cross‐coupling and subsequent oxidative ring closure reactions of the perylene units.

Study on Cost Economics of both Polymer and Metal Centrifugal Pumps

“…It was suggested that many polymer like glass fibers, carbon fibers, aramid fibres, basalt fibres, thermoplastic, thermosetting, polyester resin, epoxy resign and vinyl ester resign. Langhals et al, (2014) identified technical polymers by means of their remarkably strong auto fluorescence. The time constants of this fluorescence proved to be characteristic for the individual polymers and could be economically determined by integrating procedures.…”
