Inducing Chirality and Chiral Instabilities in Ferrogels with Homogenous Magnetic Fields

open access: yesAdvanced Functional Materials, Volume 36, Issue 6, 19 January 2026.
By pre‐aligning magnetic particles into chains, significant chiral deformations are induced by fixing the base of a cylindrical actuator and applying a homogeneous magnetic field. Subsequent base rotation can drive the system into metastable states. Further rotation or reduction of field strength triggers a chiral instability, characterized by a switch

Uptake of Hg2+ by picocyanobacteria in natural water from four Andean lakes

open access: yesE3S Web of Conferences, 2014
In lake food webs, planktonic bacteria and algae represent the greatest bioconcentration step for Hg2+ and monomethyl-Hg (MeHg). As they are the most abundant organisms in planktonic trophic webs and also the main food resource for herbivorous plankton ...

Rhombohedral R3c to orthorhombic Pnma phase transition induced by Y-doping in BiFeO3 [PDF]

open access: yes, 2018
In this work we study, by means of ab initio calculations, the structural, electronic and magnetic properties of Y-doped BiFeO3 compounds. We determine that there is a morphotropic phase boundary at an yttrium concentration of , where the structure ...

Fluorescent Dyes for Probing Intracellular and Subcellular Polarity

open access: yesChemistry–Methods, Volume 6, Issue 1, January 2026.
Fluorescent probes are crucial tools for measuring cellular microenvironment polarity, a parameter that influences physiological organelle function and diseases such as cancer. This text details the probes' physicochemical principles, intracellular targeting strategies, and key photophysical parameters for polarity estimation.
