Modeling and Simulation of Olefin Polymerization at Microstructure Level

A new model based on a combination of the polymeric multigrain and multilayer models has been developed to predict the polymerization rate, particle growth, morphology, effective parameters on broadening of the molecular weight distribution, number and weight average of the molecular weight, isotacticity index and bulk density of polymer. Mathematical correlations and the kinetics used in t...

Photolithographic olefin metathesis polymerization.

Patterning functional materials is a central challenge across many fields of science. The ability to lithographically fabricate micro- and nanostructures has been one of the most impactful technological breakthroughs of the last century. In part due to the complexity of the chemical processes in photoresists, there is a limited variety of materials that can currently be patterned by photolithog...

Modeling and Simulation at SYSTEM LEVEL

As products become more complex and fast-paced market conditions shorten product development lead times, design engineers are increasingly turning to modeling and simulation to reduce design cycle time, provide insight into complex problems, reduce costs and shorten both time-to-market and time-to-volume. Modeling and simulation can also help reduce the amount of testing that must be done durin...
