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...

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...

In a randomized controlled trial involving hundreds of university students, we provide relative performance feedback specifically designed to reduce low performers' demoralization, by dynamically assigning students to small leaderboard groups that share a similar score in a semester-long online...
