“…|C k (ω)| 2 represents the harmonics generation from the nucleus k, which has been extensively investigated in previous research work. [40,41] From Fig. 2(e), we can see that the difference of the harmonic intensities at alignment angle θ = 0 • including and ignoring interference effect is small.…”

We investigate the ellipticity of the high-order harmonic generation from the oriented $\textrm{H}_{2}^{+}$ exposed to a linearly polarized laser field by numerically solving the two dimensional time-dependent Schr$\ddot{\textrm{o}}$dinger equation (2D TDSE). Numerical simulations show that the harmonic ellipticity is remarkably sensitive to the alignment angle. The harmonic spectrum is highly elliptically polarized at a specific alignment angle $\theta = 30^\circ $, which is insensitive to the variation of the laser parameters. The position of the harmonic intensity minima indicates the high ellipticity, which can be attributed to the two-center interference effect. The high ellipticity can be explained by the phase difference of the harmonics. The results that we obtain facilitates the synthesis of a highly elliptical isolated attosecond pulses with duration down to 65 as, which can be served as a powerful tool to explore the ultrafast dynamics of molecules and study chiral light-matter interaction.

“…The higher CO 2 permeance (42 GPU) and CO 2 /N 2 selectivity (54) of the membrane C2, compared to those of the membranes T6 and C1, can be explained by the combination of the above‐mentioned effects. First, CO 2 permeance of TFC membranes, through the solution diffusion mechanism, is inversely proportional to the thickness of membranes separation layers 3,34,35 . In addition, a membrane with a high surface roughness would provide large surface area for incoming CO 2 gas molecules and increase their adsorption on the membrane surface 36,37 .…”

Different top layer fabrication methods (amine‐first, acid‐first, spin coating), organic phase solvents (hexane, heptane, mixed hexane/heptane), acid acceptors (triethylamine, sodium carbonate, sodium hydroxide), and surfactant sodium dodecyl sulfate concentrations (0, 0.05, and 0.1 wt%) were utilized to fabricate thin film composite polyamide membranes for CO2/N2 separation. The results, according to an L9 orthogonal array of Taguchi approach, showed that employing acid‐first method increases both CO2 permeance and CO2/N2 selectivity of the membranes at a feed gas pressure of 3 bars. On the other hand, sodium hydroxide, and triethylamine should be used, as acid acceptors, to maximize CO2 permeance and CO2/N2 selectivity, respectively. Moreover, the use of hexane solvent and 0 wt% surfactant led to maximum permeance, while, hexane solvent and 0.1 wt% surfactant were needed to reach the highest selectivity. The above level setting of synthesis parameters also resulted in the minimum sensitivity of the fabrication process to the noise factors effects. As shown by the analysis of variance, acid acceptor, and organic solvent types were the most influential parameters on CO2 permeance and CO2/N2 selectivity, respectively. The effects of fabrication method and surfactant concentration, as single factors, on permeation/selectivity responses were also investigated.

“…The electric field curve can be regulated by adjusting the parameters [19], which induces the change of dynamic process for electrons in the two-dimensional plane. Recently, the counter-rotating two-color circularly polarized (CRTC) laser fields are used to enhance and suppress high-order harmonic generation of + H , 2 [20]. In the CRTC laser field, the yield of NSDI strongly depends on the amplitude ratio of the electric field [21].…”

We investigate the nonsequential double ionization (NSDI) of linear triatomic molecules by the counter-rotating two-color circularly polarized (CRTC) laser fields with a classical ensemble method. The results of the simulation reveal that NSDI yield strongly connected with the relative phase. The trajectory tracking method shows that the return time of the electron is controlled by the relative phase. In addition, when we change the CRTC laser wavelengths, the relative phase of the maximum and minimum yield of NSDI also changes. This shows that the influence of the Coulomb potential in the triatomic molecules on the electron return process cannot be ignored. This work will effectively promote the electronic dynamics study of NSDI for the triatomic molecule.
