Optimization of deep eutectic solvent based liquid phase microextraction of PAHs in environmental samples using response surface methodology [PDF]

Journal of the Serbian Chemical Society
The presence of polycyclic aromatic hydrocarbons (PAHs) in wastewater poses significant health risks. To address this, a novel deep eutectic solvent- based ferrofluid (DES-ferrofluid) was developed for liquid phase microextraction with back extraction ...

Travelling wave solutions on an axisymmetric ferrofluid jet [PDF]

, 2019
We consider a potential flow model of axisymmetric waves travelling on a ferrofluid jet. The ferrofluid coats a copper wire, through which an electric current is run.

Preparation of Ferrofluid Sealing Ship Stern Shaft and Design of its Seal Structure

, 2011
Ferrofluid is prepared with the chemical method in order to seal the ship stern shaft. Three types of ferrofluid are obtained. Their magnetic particles all are Fe3O4, but their base solutions are separately water, oil and fluorine ether oil. Experimental
