Enantioselective Determination of Chiral Fungicides in Food Samples Using Automated Dispersive Microextraction Coupled With UHPLC–MS/MS

Food Frontiers, Volume 7, Issue 2, March 2026.
The use of fatty acids and bio‐derived solvents eliminates the need for toxic solvents and, when combined with automated workstations, enables parallel sample processing, thereby improving extraction efficiency and reducing human error. ABSTRACT An enantioselective analytical method based on automated dispersive liquid–liquid microextraction (DLLME ...

Phase transitions in a ferrofluid at magnetic field induced microphase separation

, 2001
In the presence of a magnetic field applied perpendicular to a thin sample layer, a suspension of magnetic colloidal particles (ferrofluid) can form spatially modulated phases with a characteristic length determined by the competition between dipolar ...

Magnetic Domain Texture in Fe3O4 Thin Films on SiO2 Nanospheres

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
Fe3O4 thin films grown on ordered SiO2 nanospheres form curved nanocaps with 3D geometry, inducing magnetic domain texture. X‐ray spectromicroscopy (XMCD‐PEEM), cross‐sectional electron microscopy (STEM), and polarized grazing‐incidence small‐angle neutron scattering (GISANS) reveal how topography modulates magnetization.

Rotating Hele-Shaw cells with ferrofluids

, 2000
We investigate the flow of two immiscible, viscous fluids in a rotating Hele-Shaw cell, when one of the fluids is a ferrofluid and an external magnetic field is applied. The interplay between centrifugal and magnetic forces in determining the instability

Reconfigurable ferromagnetic liquid droplets. [PDF]

, 2019
Solid ferromagnetic materials are rigid in shape and cannot be reconfigured. Ferrofluids, although reconfigurable, are paramagnetic at room temperature and lose their magnetization when the applied magnetic field is removed.

Magnetization of ferrofluids with dipolar interactions - a Born--Mayer expansion

, 2000
For ferrofluids that are described by a system of hard spheres interacting via dipolar forces we evaluate the magnetization as a function of the internal magnetic field with a Born--Mayer technique and an expansion in the dipolar coupling strength.
