A highly c-plane oriented h-WO3 membrane was successfully obtained under the optimized condition, which exhibited a maximum separation factor of 40.0 and a water permeance of 1.53 × 10-7 mol·m-2·s-1·Pa-1 in a 9010 wt % CH3COOH/water mixture. The water permeance approximately doubled compared to the previous report, possibly owing to the significantly higher degree of c-plane orientation. Furthermore, it was found that its separation ability can be maintained while stored in 9010 wt % CH3COOH/water mixture with pH less then 0 for

A central tenet in the now classic Wilson hypothesis surrounding racial earnings inequality emphasizes the elevated labor-market challenges for black workers of limited productive assets, yet the empirical evidence on this issue remains inconclusive. In this article, drawing on the Panel Study of Income Dynamics (PSID), I uncover three mechanisms that tend to underestimate the difficulty facing lower segments of the black labor force (1) the built-in bias of cross-sectional data that conflate career stages, (2) the cohort bias th
