Metal organic frameworks (MOFs) is a promising adsorbent for the removal of arsenic (As) from wastewater. The removal efficiency of As is influenced by many factors, such as the textural properties of MOFs, adsorption conditions, and As species. Examining all relevant factors through traditional...

We propose measures of the total volatility spillover, the regional volatility spillovers of 11 countries, and the directional volatility spillovers between Chinese and world equity markets from February 1996 to December 2009, based on forecast-error variance decompositions in a generalized...

Herein, in-situ synthesis of nonstoichiometric α-Fe2O3/LaFeO3 compounded with g-C3N4 and Ti3C2 MXene to form multiple Z-scheme/Schottky heterojunctions, α-Fe2O3/LaFeO3/g-C3N4/Ti3C2 (FLCT), is reported. In the FLCT, α-Fe2O3/LaFeO3 could promote carrier migration, g-C3N4 caused electrons to...

The ordinary least squares (OLS) estimator for spatial autoregressions may be consistent as pointed out by Lee (2002), provided that each spatial unit is influenced aggregately by a significant portion of the total units. This paper presents a unified asymptotic distribution result of the...
