Micro-nano heterogeneous oxides have received extensive attention due to their distinctive physicochemical properties. However, it is a challenge to prepare hierarchical structured metal oxide nanomaterials with abundant heterogeneous interfaces in a controllable way. In this work, the effective...

La 2 O 3 -based adsorbents are attractive in adsorptive desulfurization (ADS) of commercial fuels. However, their ADS activity strongly depends on the nanoparticle size (NPs) and dispersion degree of La 2 O 3 . Herein, the role of nanoconfined spaces and silanols groups (Si−OH) of...

In this paper, penalized estimating equations are proposed to estimate the index parametric components, which is of primary interest, in the partially varying-coefficient single-index models (PVCSIMs). Although some procedures have been developed to estimate the index parameter in PVCSIM, the...

The taxation of realized capital gains creates a lock-in effect, increasing an investor's expected holding period. We show that the unrealized capital gains of mutual funds are positively associated with the earnings quality of their portfolio firms. Consistent with tax-induced lock-in, the...

The mobilization and enrichment of arsenic(As) in groundwater is considered to be mainly affected by microbial dissimilation reduction, however competitive adsorption and complexation of natural organic matter(OM) complicate its mobilization in field scene. High concentration of biodegradable OM...
