CoFe2O4, CoBi0.1Fe1.9O4, CoLa0.1Fe1.9O4, and CoAl0.1Fe1.9O4 nanoparticles were successfully synthesized by the coprecipitation method. After annealing at 700 °C for 5 h, the x-ray Diffractometer results confirm that a single phase of cobalt ferrite-based nanoparticles is obtained, which is suitable for ICDD 22-1086. The addition of Bi3+, La3+ and A...

Van der Waals (vdW) heterojunctions constructed using two-dimensional (2D) materials have shown excellent properties for applications in various fields. In this study, the structural and electronic properties of 2D MoSe2/C3N and WSe2/C3N vdW heterojunctions have been investigated using first-principles calculations. The results show that the MoSe2/...

We compute the spectrum of pure spin current injection in ferroelectric single-layer SnS, SnSe, GeS, and GeSe. The formalism takes into account the coherent spin dynamics of optically excited conduction states split in energy by spin–orbit coupling. The velocity of the electron’s spins is calculated as a function of incoming photon energy and angle...

Plastic pollution and energy consumption are two of the most significant problems facing modern society. While the non-degradability of plastic leaves negative impacts on Earth’s ecosystem, fossil fuel usage as an energy source greatly contributes to air pollution and consequently human health. Scientists are focusing efforts on biodegradable mater...

The preferential sites of Cr in the μ-Co7W6 phase and its influence on electronic properties were studied by first-principles calculations based on density functional theory. The calculation results of the formation energy and defect formation energy show that the stability of the system is enhanced when Cr occupies the Co site, which indicates tha...

Epoxy resins (EPs) require the addition of flame retardants to extend their application scope. High-efficiency flame retardants typically contain halogens, which can cause tremendous harm to humans and the environment. In this study, we investigated the syntheses of new phosphorus–nitrogen flame retardants (DIT) and flame-retardant EP. DIT is compo...

The inter-ply sliding behavior is one of the important factors affecting the quality of carbon fiber composite products. In this paper, the inter-ply sliding behavior of the unidirectional prepreg was investigated for the preforming process. The inter-ply sliding resistance of prepreg under different conditions was measured by the homemade measurin...
