In comparison with other samples, the SrW0.75Ta0.25O3.975 and Sr0.875Ba0.125W0.875Ta0.125O3.9375 crystals show lower band-gap energies, although it was previously reported that the band-gap energy of tantalum-doped hex-WO3 was higher than that of pure hex-WO3 due to the Ta5+ ions with d 0 electronic configuration [24].
Although it was previously reported Goldsman would be directing, executive producer Joe Chappelle ultimately directed the installment.
We note that although it was previously reported that both L5 and D29 form plaques on a Che12 lysogen [38], they behaved as homoimmune in our experiments (Fig. S4).
