Radiation-induced segregation (RIS) of solutes in materials exposed to irradiation is a well-known problem. It affects the lifetime nuclear reactor core components by favoring radiation-induced degradation phenomena such as hardening and embrittlement. In this work, RIS tendencies face centered cubic (fcc) Ni-$X$ ($X=\mathrm{Cr}$, Fe, Ti, Mn, Si, P) dilute binary alloys are examined. The goal i...

The Nobel Prize for Physics 1920 was awarded to C.-E. Guillaume for his discovery of properties of nickel steels. He had previously observed that certain iron-nickel alloys exhibit the Invar effect i.e. an extremely low thermal expansion coefficient over a wide range of temperature. The decades since then have seen the observation of similar phenomena in other iron-based materials such as iron-...

High-entropy alloys (HEAs) comprise a novel class of scientifically and technologically interesting materials. Among these, equatomic CrMnFeCoNi with the face-centered cubic (FCC) structure is noteworthy because its ductility and strength increase with decreasing temperature while maintaining outstanding fracture toughness at cryogenic temperatures. Here we report for the first time by single-c...

Waste plastics contain a substantial number of valuable chemicals. The wastes from post-consumer as well as from industrial production can be recycled to valuable chemical feedstock, which can be used in refineries and/or petrochemical industries. This chemical recycling process is an ideal approach in recycling the waste for a better environment. Polymer cracking using a laboratory fluidized b...

The crystal structure and chemical bonding of magnetron-sputtering deposited nickel carbide Ni₁-xCx (0.05 ⩽ x⩽0.62) thin films have been investigated by high-resolution x-ray diffraction, transmission electron microscopy, x-ray photoelectron spectroscopy, Raman spectroscopy, and soft x-ray absorption spectroscopy. By using x-ray as well as electron diffraction, we found carbon-containing hcp-Ni...

Abstract The effects of various catalysts on the composition volatile pyrolysis products a plastic waste and biomass mixture (1:1) were studied, by pyrolyzing sample using slow fast heating rate. Various zeolite (β-and Y-zeolites, ZSM-5 FCC) nickel-molybdenum catalyst alumina support applied to find suitable for upgrading quality thermal decomposition mixture. A ratio 2:1 was used in experiment...

Transition metal model pseudopotential (TMMP) technique has been applied to study the short range order (SRO) in nickel alloys Ni100–x–Rhx and Ni100–x–Pdx and a copper alloy Cu100–x–Rhx (x = 2, 5, 8, 11 at. %). All these transition metal alloys form fcc solid solutions for the chosen compositions. The static electrical permittivity ε(q) was taken from the Hubbard–Sham model and/or Geldart–Vosko...
