TL;DR: In this article, Nitrogen loss, retention and bioavailability in biochar-amended soils fertilized with NH 4 + -N and NO 3 − -N were studied using leaching and pot experiments.

TL;DR: Sorption of sulfonamides on biochars is poorly understood, thus sulfamethoxazole (SMX) sorption was determined as a function of pH and SMX concentration, as well as the inorganic fractions in the biochar.

TL;DR: Investigation of the relationship between Pb(2+) adsorption and physicochemical properties of biochars produced at different pyrolytic temperatures indicated the dominant role of minerals, and results are useful for screening effective biochar as engineered sorbents to remove or immobilize Pb (2+) in polluted water and soil.

TL;DR: Results indicate that low-temperatures may be optimal for producing biochar from giant reed to improve the nutrient availability and reduce the loss of N and P with increasing temperatures.

TL;DR: Small (6−10 nm) functionalized gold nanoparticles (AuNPs) featuring different, well-defined surface charges were used to probe the uptake and distribution of nanomaterials in terrestrial plants, including rice, radish, pumpkin, and perennial ryegrass, showing that positively charged AuNPs are most readily taken up by plant roots, while negatively charged AuNs are most efficiently translocated into plant shoots.
