Silver nanoparticles synthesized with Rumex hymenosepalus .

Materials. Silver nitrate (AgNO 3) (Sigma-Aldrich, purity ≥99.5%) was used as promotor of Ag + ions and Rumex hymenosepalus root extract (Rh) as reducing agent in the synthesis of silver nanoparticles. Non-denatured ethyl alcohol (Sigma-Aldrich, purity ≥99.5%) and ultrapure Millipore water were employed as solvents in the extraction process, which used an 18.2 MΩ resistor.

Rotary Evaporation in the Kitchen - Cooking Issues

Two key components of the rotovap allow for a gentle, precise, and efficient distillation not found in conventional distilling apparatuses: 1) the solvent is removed under vacuum, which lowers its boiling point, eliminating the need for high-temperature distillation, and 2) the rotation of the evaporating flask, immersed in a heated water bath .
