Summary: The study reveals that modern soybean varieties in Brazil have higher nutrient removal compared to historical values, especially in terms of N, P, K, and Mg removal. However, over a 10-year period, the impact of plant breeding on grain nutrient concentration was significant only for N and Mg. The differences in nutrient removal patterns between Brazil and other countries suggest an integrated effect of management, genotype, and environment on nutrient removal.

Summary: Catastrophic oil spills, oily industrial wastewater, and other uncontrolled release of oils pose major global issues, threatening marine ecosystems and causing economic impact. This review addresses different oil collecting methods, with a focus on materials and technologies for oil/water separation, especially water/oil emulsion separation. Oil-absorbent materials like sponges, foams, nanoparticles, and aerogels with hydrophobic and oleophilic properties show promise in large-scale environmental and catastrophic oil spills. Oil adsorbent materials like meshes, textiles, membranes, and clays attract attention for their low-cost and easy manufacturing benefits.

Summary: In this study, TiO2 was co-modified by the addition of sulfur, nitrogen, and reduced graphene oxide, resulting in enhanced photocatalytic degradation of formaldehyde. The addition of rGO, S, and N increased critical factors in photocatalysis activity such as specific surface area, light absorption, bonding of oxygen-containing functional groups, and electron transfer capacity.

Summary: The study found that the active catalytic species involved in the hydrolysis of phosphoester is the dimeric [Mo2O8] (4-) anion resulting from the decomposition of [Mo7O24] (6-), rather than the originally assumed {Mo5O15} species. A similar study involving W instead of Mo showed a higher barrier and less stable products, in line with the non-catalytic effect found in experimental results. Density Functional Theory (DFT) calculations provided a description of the characteristics of the intermediate species.
