the commercial profile of the amoco cd mgcl2 supported polypropylene catalyst is presented. the development, the unique method of preparation/production, with emphasis on particle morphology, and the parameters affecting particle size (ps), particle size distribution (psd), and particle shape are discussed in detail. the outstanding performance of the catalyst, tailoredmade for the amoco-chisso...

The highly morphable particle raft changes its topography under an electric field without any prescribed patterns. interface is stably driven to upheave and move by metallic electrodes, paper, even human fingers.

A two-dimensional (2D) single particle model for the copolymerization of propylene-ethylene with heterogeneous Ziegler-Natta catalyst is developed. The model accounts for the effects of the initial shape of the catalyst and carck/ pore patterns on the copolymer composition, polymerization rate and the average molecular weight properties. The spherical and oblate ellipsoidal shapes of catalyst p...

Bubbles stabilised by colloidal particles can find applications in advanced materials, catalysis and drug delivery. For applications in controlled release, it is desirable to remove the particles from the interface in a programmable fashion. We have previously shown that ultrasound waves excite volumetric oscillations of particle-coated bubbles, resulting in precisely timed particle expulsion d...
