Abstract:
... Toxic inorganic depressants are commonly used in the flotation separation of polymetallic sulfide ores and it is desirable that they can be replaced by environmentally benign substances. Serpentine, a common gangue mineral encountered in complex sulfide ores, has been found to be an efficient depressant for ferric sulfide (e.g., pyrite). Serpentine was tested as a potential selective depressant in ...

Abstract:
... Liquid-phase exfoliation of graphite is a promising method to produce graphene in large quantities. Selection of the solvent is the most important factor in determining the productivity of liquid-phase exfoliation and stability of the graphene dispersion. However, only low concentrations of graphene dispersion have been achieved in most of the solvents, and the solvents usually employed are toxic ...

Abstract:
... It is commonly true that a diluted colloidal suspension is more stable over time than a concentrated one because dilution reduces collision rates of the particles and therefore delays the formation of aggregates. However, this generalization does not apply for some engineered ligand‐coated nanoparticles (NPs). We observed the opposite relationship between stability and concentration of NPs. We tes ...

The zebrafish fish embryo toxicity (FET) test is increasingly employed for alternative toxicity studies, yet our previous research identified increased sensitivity of zebrafish slightly older than embryos employed in FET methods (0–4 d postfertilization [dpf]). We identified rapid steady‐state accumulation of diphenhydramine across zebrafish embryo and larval stages. However, significantly (p < 0. ...
