Summary: The impact of calcium-aluminum layered double hydroxides (Ca-Al-LDH) on soil cadmium (Cd) adsorption and bioavailability in different soil-crop systems has been studied. Ca-Al-LDH effectively remediates heavy metal pollution through surface complexation, surface precipitation, and metal cation exchange. It significantly decreased soil Cd, zinc (Zn), and lead (Pb) levels and reduced Cd content in bioaccumulator crops. However, caution should be exercised when using Ca-Al-LDH in areas with low Cd contamination or when growing vegetables with low Cd accumulation. It provides a theoretical and practical foundation for soil health management and the remediation of Cd-contaminated agricultural soils.

Summary: The high-pressure phase transition behaviors and pressure-dependent compressibility of K2X (CO3)2 are studied using first-principles calculation from ambient pressure to 30 GPa. The reversible structural phase transitions of K2X(CO3)2 are determined based on enthalpy difference and cell volume collapses. The structural phase transition points of K2Ca(CO3)2 are found at around 3.3 GPa and 10.3 GPa, while those of K2Mg(CO3)2 are found at about 6.2 GPa and 22.6 GPa. The Ca+ and Mg+ coordination polyhedra are more compressible compared to the high axial rigidity of C-O bonds in [CO3] groups. The displacement behavior of the Ca+ and Mg+ coordination polyhedra occurs simultaneously with the rotation behavior of [CO3] groups during compression and is reversed by the structural phase transition.

Summary: The research aimed to investigate the possibilities of processing a low-grade high Ca fly ash (FA) to enhance its potential utilization. Size separation and mechanical activation were tested to compare their effectiveness. Chemical analysis revealed significant variations in composition between different size fractions of FA, with the <32 µm fraction having higher Si and Al content. Grinding the coarse FA resulted in an increase in <1 µm particles, but also caused aggregation and agglomeration after 30 minutes, with an average particle size of 5.49 µm. The optimal grinding time for the highest CaO uptake was around 20-30 minutes, which resulted in over 160 mg/g absorbed CaO within 20 days. FT-IR analysis showed important structural changes in the mechanically activated samples. Classification alone significantly decreased the compressive strength by up to 33%, while mechanical activation of the coarse fraction led to a more than five-fold increase in compressive strength with the optimal grinding time.

Summary: Foamed ceramics were prepared using vanadium tailings and lead-zinc tailings as the main raw materials, with the addition of gold tailings, waste glass powder, other fluxes and SiC foaming agents. The effects of Ca and Mg in the fluxes of calcite, talc, and dolomite on the properties of the samples were investigated and analyzed. It was found that calcite promotes the formation of the augite phase, talc promotes the formation of the albite phase, and dolomite combines the advantages of both. The formation of albite reduces the viscosity of the melt, while the formation of augite greatly enhances the strength of foamed ceramics. By adding 8% dolomite, a low-cost, lightweight and high strength foamed ceramic partition with specific properties can be prepared.

Summary: Electrochemical and immersion tests were conducted to characterize the bio-corrosion resistance of as-extruded Mg-Ca binary alloys with submicron grain size. The microstructures were further characterized by optical microscopy (OM), scanning electronic microscopy and transmission electron microscope (TEM). The Mg-2Ca alloy extruded at 300 degrees C (2Ca-300) exhibits the lowest current density of 1.683 mA·cm-2 and corrosion rate of 22.14 g·m-2·day-1 in simulated body fluid, which is comparable with that of pure Mg. Ca addition can reduce grain size of as-extruded Mg alloy and decrease the corrosion rate. The formed Mg2Ca phases would accelerate the local galvanic corrosion and protect the alpha-Mg matrix simultaneously due to the lower electrode potential. The lower defect density, finer grain size, and weaker basal texture intensity contribute to the excellent bi-corrosion resistance of the 2Ca-300 alloy.

Summary: This study investigates the degradation of alkali-activated material (AAM) exposed to sulfuric acid, categorizing it into physical and chemical degradation. The researchers examine the impact of curing method, raw materials, and their proportions on the degradation, finding that a smaller liquid-filler ratio, heat-curing, and the use of specific alkali activator solutions can reduce both types of degradation. They also discuss the applicability of XRD and SEM-EDS in analyzing the chemical compositions of AAMs exposed to sulfuric acid.

Summary: Processes in hillslope soils pose challenges for agricultural production and soil management due to their unique characteristics and high erosion risk. This study aimed to investigate the impact of erosion-affected hillslope position on soil properties and identify water flow patterns using tracers. Laboratory experiments were conducted using soil cores and columns, and the results showed faster leaching of irrigated rainwater in the footslope column. Variability in tracer experiments indicates the influence of plant roots and soil fauna activity. The findings highlight the importance of further field experiments to examine the impact of surface runoff and subsurface flow on a larger scale.

Summary: Nutrient leaching from agricultural soils can lead to economic losses for farmers and environmental degradation. This study collected and analyzed leachates from different positions in a vineyard over a two-year period and found that nutrient concentrations were higher at the footslope compared to the hilltop and backslope, but only in intra-row positions. The study also confirmed that the vineyard intra-row was the spatial origin of nutrient leaching along the slope, highlighting the importance of optimizing vineyard management practices.

Summary: This study focuses on estimating the precipitation fraction in the soil water of a sloped vineyard in Zagreb, Croatia. The research shows that exploration of hillslope soils can be challenging due to heterogeneity and anthropogenically induced processes. The isotopic signature of the soil water indicates that water mixing primarily happens in the shallower part of the hillslope. Furthermore, precipitation fractions vary significantly based on depth and position in the vineyard, with higher fractions in surface and subsurface runoff.

Summary: Fly bioash (FBA) from biomass-fuelled facilities can effectively improve acidic and nutrient-deficient soils, but there are concerns about potential radioactive contamination. This study evaluated the impact of alkaline FBA on soil pH and radionuclide concentrations in a Luvisol soil and sunflower seeds. After 54 months, FBA significantly increased soil pH and seed yield without altering radionuclide concentrations. The radiological footprint of FBA was lower compared to non-arable topsoils and commonly used mineral fertilisers, indicating its potential for sustainable agri-food production. Further research is needed to investigate the effects of FBA application across different environmental conditions.
