Inorganic salts and organic matter effects on nanorod, nanowire, and nanoplate MoO3 aggregation, dissolution, and photocatalysis

Inorganic salts (NaCl and CaCl2) and organic material (humic acid and extracellular polymeric substances) have differing effects on the aquatic stability and photocatalytic activity of structurally different MoO3 materials.

Polystyrene nanoplastics accumulate in ZFL cell lysosomes and in zebrafish larvae after acute exposure, inducing a synergistic immune response in vitro without affecting larval survival in vivo

Polystyrene nanoplastics are internalized in zebrafish liver cells, accumulating in lysosomes, and in zebrafish larvae but do not affect the larval suvival to a lethal infection.
