Preparation and application of macromolecules with a fluorescence effect in polymer processing
In this study, 9-anthracenemethyl methacrylate (AMMA) and styrene (St) as monomers and benzoyl peroxide as an initiator were used to synthesize P(St-co-AMMA), a macromolecule tracer with a fluorescence effect, via free radical copolymerization.

A New Approach for Modelling Residence Time Distribution in a Co-rotating Twin Screw Extruder
A model to determine the residence time distribution (RTD) in a co-rotating twin screw extruder is proposed. The method couples a thermomechanical approach with a chemical engineering approach and allows us to obtain the RTD without a fitting ...

Onset velocity of circulating fluidization and particle residence time distribution: A CFD-DEM study
Until now, the onset velocity of circulating fluidization in liquid-solid fluidized beds has been defined by the turning point of the time required to empty a bed of particles as a function of the superficial liquid velocity, and is reported to be only
