Improved method for separation of silver nanoparticles...

Transmission electron microscopy revealed silver nanoparticles with an average diameter of 13.0 nm when synthesized through ethanol precipitation, which is advantageously smaller. This result suggests that the silver nanoparticles size can be fine-tuned by changing the separation mode during purification from plant extract.

Metal directional crystallization: A sustainable green separation

Vacuum distillation is an environmentally friendly separation technology. Theoretical and technological research on the vacuum distillation of lead–bismuth alloys revealed [16] that the saturated vapor pressures of Pb and Bi are similar, resulting in a less-than-ideal separation effect. Multi-step vacuum distillation can separate Pb and Bi with sub-optimal raw material adaptability.
