Introduction to Metal Atom Syntheses

Copolymerization of ethene with norbornene using palladium(II) α-diimine catalysts: Influence of feed composition, polymerization temperature, and ligand structure on copolymer properties and microstructure

“…In this process, square planar Ni complexes with anionic P o O chelate ligands were applied. Although these catalysts were later tuned to give high molar mass products [14][15][16][17], a breakthrough was achieved with the discovery by Brookhart et al [18][19][20] that cationic Ni and Pd complexes with bulky aryl-substituted a-diimine ligands are very efficient catalysts for the polymerization of ethene and a-olefins. 1 These catalysts are less sensitive to polar impurities and functional groups [26][27][28] and even allow the suspension polymerization of ethene in aqueous media [29][30][31][32][33].…”

Nanoparticles Prepared by Salt Vapor‐Solvent Vapor Cocondensation and Controlled Nucleation: Metal Sulfides (ZnS, CdS, CdSe, PbS), and Metal Halide (LiF). Size, Aggregates, Structures, Digestive Ripening, Superlattices, and Impregnations

“…A solvent shower was inserted into the reaction vessel for solvent delivery. The reactor vessel was then surrounded by a liquid dewar and cooled to 77 K [2, 37,38].…”

Size evolution of palladium nanoparticles from low-temperature solvated atoms

“…In this work, we are focused in the synthesis of Pd nanoparticles by the chemical liquid deposition method (CLD), developed by Klabunde et al [17]. This method involves the resistive evaporation of bulk metal and codeposition with organic solvents at 77 K to obtain colloidal dispersions of organic-coated metal nanoparticles.…”
