Retracted Article: The controlled synthesis of g-C3N4/Cd-doped ZnO nanocomposites as potential photocatalysts for the disinfection and degradation of organic pollutants under visible light irradiation [PDF]

open access: yesRSC Advances, 2021
The in situ growth of well-dispersed Cd-doped ZnO nanoparticles (Cd-ZnO NPs) on graphitic carbon nitride (g-C3N4) nanosheets was successfully achieved through the co-precipitation method for the formation of Cd-doped ZnO nanocomposites with g-C3N4 (Cd ...

Ordering in ternary nitride semiconducting alloys [PDF]

open access: yesPhysical Review B, 2012
We present a thorough theoretical study of ordering phenomena in nitride ternary alloys GaInN, AlInN, and AlGaN. Using the Monte Carlo approach and energetics based on the Keating model we analyze the influence of various factors on ordering in bulk crystals and epitaxial layers.

The influence of heterogenous porosity on silicon nitride/steel wear in lubricated rolling contact [PDF]

open access: yes, 2000
Heterogeneous porosity is detected on the surface and subsurface of hot isostatically pressed (HIPed) silicon nitride spherical rolling elements. The extent of the localised porosity accounts for an area of 6% of the rolling element surface and 4% of the

High-throughput search for RE (La, Ce and Y) contained stoichiometric compound in steels

open access: yesMaterials Research Express, 2021
The design of rare earth (RE) bearing steels requires a thorough understanding of the formation tendency of RE involved phases in steels, while searching for binary and ternary compounds with a wide variety of composition and permutation need a ...

High-temperature phase relations of ZrN–ZrO2–Y2O3 ternary system

open access: yesJournal of Advanced Ceramics, 2018
Zirconium nitride (ZrN) ceramics were prepared via hot pressed sintering (HP) at 1750 °C in N2 atmosphere with ZrO2–Y2O3 as sintering additive. X-ray diffraction was applied to analyze the phase composition of the as-prepared ceramics to study the high ...

Tensile Creep Properties of Cr-Si Alloys at 980 °C in Air—Influence of Ge and Mo Addition

open access: yesMetals, 2021
The tensile creep behavior of Cr-Si alloys with Cr ≥ 91 at.% was investigated in air at 980 °C with a constant load of 50–100 MPa. Additionally, the influence of substitutional alloying additions of 2 at.% Ge and Mo, leading to ternary alloys was studied.

Characterisation of ternary TixV1−xNy nitride prepared by mechanosynthesis [PDF]

open access: yesCeramics International, 2012
In the present manuscript the authors have systematically investigated the composition and microstructure of a series of ternary nitrides (Ti xV1-xNy) (0.0 ≤ x ≤ 1.0) prepared by mechanosynthesis, using XRD, SEM, EELS, XAS and TGA. The ternary titanium-vanadium nitride (TixV1-xNy) has been obtained in all range of compositions by the mechanical ...
