Phase formation and thermal stability of ultrathin nickel-silicides on Si(100) [PDF]
The solid-state reaction and agglomeration of thin nickel-silicide films was investigated from sputter deposited nickel films (1-10 nm) on silicon-on-insulator (100) substrates.

Review on recovery of valuable metals from complex copper–cobalt co-associated mines
Copper and cobalt, both strategic metals, play an indispensable role in many fields, such as national infrastructure and defense science and technology. Copper, one of the earliest nonferrous metals discovered, extracted, and applied by humans, teams up ...

Beneficial influence of nanocarbon on the aryliminopyridylnickel chloride catalyzed ethylene polymerization [PDF]
A series of 1-aryliminoethylpyridine ligands (L1―L3) was synthesized by condensation of 2-acetylpyridine with 1-aminonaphthalene, 2-aminoanthracene or 1-aminopyrene, respectively.

High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot
