“…According to the MCDF results from [8], the energy of the level 4s 2 4p 2 P 3/2 is equal to 790710 cm -1 and Δ = -0.14%. The agreement between our results and the experimental NIST data is [6,9], whereas the data for this level are missing in [10,11]. The deviations are even smaller for other lev els.…”

“…Nevertheless, the results from [10,11] for the larger part of their presented level energies are slightly more accurate. On the other hand, the data from [10,11] are given for a comparatively small number of energy levels, and some levels existing in the NIST database are not determined. For the ion W 42+ , only the results from [12] are closer to the experimental data compared to the QR data for a larger part of the presented levels.…”

The ab initio quasirelativistic Hartree-Fock approximation was used to determine spectroscopic parameters for the multicharged tungsten ions with an open 4p shell. The configuration interaction method based on the transformed radial orbitals was applied to include the electron-correlation effects. The relativistic effects were taken into account in the Breit-Pauli approximation for the quasirelativistic Hartree-Fock radial orbitals. The complete energy level spectra were calculated for the 4s

“…The level energies for such ions determined in the QR approach are presented in [13]. That work contains the overview of various studies of the tungsten ions and the comparison of our QR results with available data [8,11,12,[14][15][16][17][18][19]. In the very recent work [20] the multiconfiguration Dirac-Hartree-Fock method (MCDHF) is applied to determine level energies and radiative lifetimes for eight Kr-like ions, including the W 38+ ion.…”

The ab initio quasirelativistic approximation was used to derive transition data for the multicharged tungsten ions W 38+ -W43+ with an open 4p shell. The configuration interaction method with transformed radial orbitals was applied to include electron correlation effects. The relativistic effects were taken into account in the Breit-Pauli approximation for the quasirelativistic Hartree-Fock radial orbitals. The level energies E, radiative lifetimes τ, and Landé g-factors were calculated for the 4s 4d, and 4s4pN+1 configurations of six tungsten ions. The radiative transition wavelengths λ, spontaneous emission transition probabilities A and their uncertainties for the electric dipole, electric quadrupole, electric octupole, magnetic dipole and magnetic quadrupole transitions among the levels of these configurations are presented.

Exacerbated environmental concerns about petroleum‐based plastics provide the impetus to foster sustainable poly(lactic acid) (PLA) based food packaging. Nonetheless, PLA has its foibilities such as its brittleness, higher gas permeability, and slow crystallization. With the intent to mitigate the above shortcomings, we report a maiden effort for the fabrication of PLA/crystalline silk nano‐discs (CSNs) based bionanocomposites by melt‐extrusion for high temperature engineering and food packaging applications. Acid hydrolyzed silk fibroin from muga silk (Antheraea assama) yields CSNs, a crystalline hydrophobic discotic nanofiller with diameter of ∼50 nm and thickness ∼3 nm. At optimum loadings of 1 wt % uniform dispersed CSNs with percolated network structures covering the entire matrix can be seen. Due to enhanced crystal nucleation density, water vapor, and oxygen permeability reduced by ∼30% and ∼70%, respectively. Enhancement in toughness, percentage elongation, and tensile strength up to ∼65%, ∼40%, and ∼10%, respectively, is obtained. Onset of thermal decomposition for the PLA/CSN improved ∼10 °C, confirming the role of CSN in enhancing melt stability. Accordingly, this investigation renders a novel non‐invasive approach for increasing the crystallinity with improvement in thermomechanical and barrier properties which make this bionanocomposite, a promising candidate for food packaging applications. © 2018 Wiley Periodicals, Inc.
