Highly active half-metallocene type chromium (III) catalysts for ethylene polymerization have been developed. High molecular weight linear polyethylene (Mn > 1 000 000 g/mol) was produced by these ...

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

This article studies periodic event-triggered networked control for nonlinear systems, where the plants and controllers are connected by multiple independent communication channels. Several ...

Layered, poorly crystalline Mn(IV)O2 phases are abundant in the environment. These mineral phases may rapidly oxidize Cr(III) to more mobile and toxic Cr(VI) in soils. There is still, however, little ...

We propose to model periodic structures by equivalent multiconductor transmission lines (MTLs). The developed technique is based on a multimodal representation of the periodic structure unit cell, ...
