TL;DR: Ceria (CeO2) supports are unique in their ability to trap ionic platinum (Pt), providing exceptional stability for isolated single atoms of Pt, and upon oxidation the Pt–Sn clusters readily revert to the atomically dispersed species on CeO2, making Pt– Sn/Ce O2 a fully regenerable catalyst.

TL;DR: In this article, the formation of either fibers or micrometer-sized polymers is presented, where the morphologies and properties of polymers are pivotal for their manufacturing and processing at the industrial scale.

TL;DR: This work combines X-ray diffraction and spectroscopy to probe each step of the birth and life of a MgCl2 -based Ziegler-Natta catalyst, namely the formation of high surface area M gCl2 by dealcoholation of an alcoholate precursor, the TiCl4 grafting, and the subsequent activation by triethylaluminum as co-catalyst.

TL;DR: In this paper, a spectroscopic toolbox was developed for quality assurance purposes of a third generation Ziegler-Natta catalyst for ethylene polymerization, which was exposed singly to heat, dry air, and moisture to study the specific environmental factors.

TL;DR: In this paper, a b-oriented silicalite-1 monolayer on a commercial porous ceramic substrate has been used for fabrication of well-intergrown, oriented zeolite membranes with tunable chemical properties.
