[en] The proximity effect can be explained by solving the complete Landau-Ginzburg equation. The solution of the equation naturally produces a simple and explicit expression of the transition temperature for a film sandwich composed of a bulk superconductor and a normal metal. The general result obtained is T_cSN/T_cS=t=1-B₀d_Nξ_S/(d_S²+3d_Nd_S/k) or an alternative, t=[1-B₀d_Nξ_S/(d_S²+3d_Nd_S/k)]^1/2. The theoretical calculations fit experimental results very well

[en] Highlights: • The effects of task complexity and operators’ knowledge and experience level on team situation awareness (TSA) and workload were studied through simulator experiments. • Task complexity had a significant influence on the operator’s situation awareness (SA) and TSA level. • The level of knowledge and experience had significant effects on the operator’s SA and TSA level. • The level of knowledge and experience and task complexity had different effects on the workload. With the improvement of digital level of main control rooms (MCRs) of nuclear power plants (NPPs), the issue of situation awareness (SA) of operator becomes particularly prominent in NPP operations. More and more scholars have done some research on SA and team situation awareness (TSA). In order to explore the effects of performance shaping factors (PSFs) on SA, TSA and workload, the effects of task complexity and operators’ knowledge and experience level on operators’ SA, TSA and workload were studied through simulator experiments. The results show significant effects on the operators’ SA and TSA levels. The higher the complexity of task, the lower the level of operators’ SA and TSA; and the higher the level of knowledge and experience, the higher the level of operators’ SA and TSA. Experiments also show that task complexity and the level of knowledge and experience have a significant impact on the operator's workload. The higher the task complexity is, the higher the operator’s workload level is, and the higher the knowledge and experience level is, the lower the workload level of the operator is. The research results provide a theoretical basis for improving the level of SA and reducing workload, and provide theoretical and experimental guidance for identifying the impacts of PSF on SA, TSA and workload.

[en] The FRACS parameterizations, labeled as FRACS-C, have been improved in order to predict the presence of isotopes near the proton drip line produced in projectile fragmentation reactions. By investigating the cross sections for proton-rich isotopes in a series of reactions with energies ranging from intermediate to relativistic, it is shown that the FRACS-C parameterizations can predict isotopes near the proton drip line considerably well. The FRACS-C parameterizations are suggested to serve as an effective tool for predicting the presence of proton-rich isotopes with large asymmetry in a projectile fragmentation reaction. Different reactions have been investigated to check these results.

[en] Graphical abstract: Magnetization curve of TMT-MRGO composite. - Highlights: • A novel magnetic composite TET-MRGO is prepared. • TET-MRGO is highly magnetic and can be easily separated from aqueous solution. • TET-MRGO shows excellent adsorption capacity for Cu(II) (209.1 mg g"−"1). • TET-MRGO shows excellent adsorption selectivity toward Cu(II). • The reusability of TET-MRGO is encouraging and hopeful for practical use. - Abstract: In the present paper a new type of triethylenetetramine-magnetite reduced graphene oxide (TET-MRGO) composite showing a high adsorption capacity (209.1 mg g"−"1) toward Cu(II) ions was prepared. The morphological, structural, and magnetic properties of TET-MRGO were characterized using infrared spectrometer, X-ray diffraction, Scanning Electronic Microscope, nitrogen adsorption–desorption measurement, Raman spectroscopy, and Transmission Electron Microscopy. TET-MRGO exhibits strong saturation magnetization (42.13 emu g"−"1) and can be easily separated from aqueous solution by an external magnetic field. A series of batch adsorption experiments were systematically conducted to study the adsorption property of TET-MRGO. The high adsorption capacity, excellent selectivity, and effective adsorption–desorption results indicated the prepared TET-MRGO composite could be an effective adsorbent for removing Cu(II) ions from aqueous solution.
