Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

Structural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

Experimental and numerical investigation on the flexural response of GFRP‐reinforced SFRC beams

Structural Concrete, EarlyView.
Abstract In order to address the challenges related to the deformability and ductility of concrete beams reinforced with fiber reinforced polymer (FRP) bars, an alternative solution involving steel fiber reinforced concrete (SFRC) has been proposed. In the present study, a total of seven beams—including one steel‐reinforced reference beam and six glass

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Varying effects of stream restoration on riparian soil carbon persistence and methane emissions in the southern Rocky Mountains, United States

Restoration Ecology, EarlyView.
Abstract Introduction Channel incision can disconnect streams from their floodplains, potentially depleting carbon (C) in riparian soils by stimulating microbial decomposition. Stream restoration may offer an opportunity to replenish soil C pools by saturating riparian soils with water and slowing microbial activity.

Advances in Floating Solar Desalination Systems

Water and Environment Journal, EarlyView.
This review critically classifies floating solar desalination systems into five main categories and compares their thermal performance, productivity and technological limitations. Membrane‐based and multieffect systems showed the highest efficiencies, while traditional designs remain limited by heat losses and scaling.
