TL;DR: Results indicate that the perovskite-type LaFeO3/g-C3N4p-n heterostructured photocatalyst obtained, in contrast to the pure constituents, enabled improved visible-light absorption, and more efficient separation and migration of charge carriers via solid p- n heterojunction interfacial effect.

TL;DR: The adsorption thermodynamics data presented that dye removal was a spontaneous, endothermic and physical reaction and the synthesized MIL showed high reusability and stability over three cycles.

TL;DR: The results suggest that different animal species had significant effects on the diversity, abundance, and persistence of ARGs, where the abundance of transposons, heavy metal concentration, total nitrogen level, and the dosage and duration of exposure to antibiotics may explain these differences.

TL;DR: In general, CuO, ZnO, and SnO2 show the highest sensitivity to H2S; therefore, most of this review is dedicated to these oxides.

TL;DR: Granulated Blast Furnace Slag, which is traditionally considered as a waste material, is used as a replacement and partially reactive material in FA geopolymer pavement applications, and microstructural analysis indicated the coexistence of Calcium Silicate Hydrate (CSH) and Sodium Alumino Silicates Hydrate products in FA geopolitical stabilized LS/GBFS blends.

TL;DR: A series of AgX (X = I, Br)/CuBi2O4 composites are fabricated through an in-situ precipitation method and exhibit much higher photocatalytic activity than that of pure CuBi 2O4.

TL;DR: The binding of Cd and Cu to dissolved organic matter (DOM) derived from compost (CP) and rice straw (ST) was studied through an approach combining parallel factor (PARAFAC) analysis and two-dimensional correlation spectroscopy (2DCOS).

TL;DR: There is a great interest in nano-zinc as improving the knowledge about individual forms of zinc and their uptake and assimilation within higher plants may be the first step towards a wider involvement of zinc nanoparticles into agriculture.

TL;DR: The results showed that ozone MNBs can greatly improve remediation efficiency and represent an innovative technology for in situ remediation of organics-contaminated groundwater.

TL;DR: It turned out that the synergistic effect between doping P and SOVs onTiO2 greatly improved transfer and separation efficiency of photogenerated charges, thus significantly enhanced the visible light photocatalytic performance of TiO2.

TL;DR: The improved photocatalytic activity is attributed to the formation of a p-n heterojunction between Ag2O and Bi5O7I, allowing the efficient utilization of solar energy and high separation efficiency of photogenerated electron-hole pairs.
