g-CN Modified with Metal Sulfides for Visible-Light-Driven Photocatalytic Degradation of Organic Pollutants.

Graphitic carbon nitride (g-CN) proved to be a promising semiconductor for the photocatalytic degradation of various organic pollutants. However, its efficacy is limited by a fast electron hole recombination, a restricted quantity of active sites, and a modest absorption in the visible range. To overcome these limitations, g-CN-BiS and g-CN-ZnS composites were effectively produced utilizing a starch-assisted technique.

Mechanochemical Activation of Waste Clay Brick Powder with Addition of Waste Glass Powder and Its Influence on Pozzolanic Reactivity.

The availability of industrially used supplementary cementitious materials (SCMs, e.g., fly ash) decreases due to the rise in renewable energy sources and recycling technologies.

Phosphine Generation Pathways on Rocky Planets.

The possibility of life in the venusian clouds was proposed in the 1960s, and recently this hypothesis has been revived with the potential detection of phosphine (PH) in Venus' atmosphere. These observations may have detected ∼5-20 ppb phosphine on Venus (Greaves , 2020), which raises questions about venusian atmospheric/geochemical processes and suggests that this phosphine could possibly be generated by biological processes. In such a claim, it is essential to understand the abiotic phosphorus chemistry that may occur under Venus-relevant conditions, particularly those processes that may result in phosphine generation.

Occurrence and cycling of trace elements in ultramafic soils and their impacts on human health: A critical review.

The transformation of trace metals (TMs) in natural environmental systems has created significant concerns in recent decades. Ultramafic environments lead to potential risks to the agricultural products and, subsequently, to human health. This unique review presents geochemistry of ultramafic soils, TM fractionation (i.
