Adsorption of ions from aqueous solutions by ferroelectric nanoparticles [PDF]
Physical Review Applied 23, 014081 (2025)The fundamental aspect of physics of ferroelectric materials is the screening of uncompensated bound charges by the dissociative adsorption of ionic charges from the environment. The adsorption of ions can be especially strong when the ferroelectric undergoes the temperature-induced transition from the paraelectric phase to the ferroelectric state ...

Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture
Advanced Engineering Materials, EarlyView.Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially

Synthesis of cobalt nanowires in aqueous solution under an external magnetic field
Beilstein Journal of Nanotechnology, 2016 In contrast to the majority of related experiments, which are carried out in organic solvents at high temperatures and pressures, cobalt nanowires were synthesized by chemical reduction in aqueous solution with the assistance of polyvinylpyrrolidone (PVP)

3DRISM Bridge Functional for the Aqueous Solutions of Carbon Nanomaterials [PDF]
arXiv, 2011 In the paper a bridge functional for the closure relation of the three-dimensional reference interaction model (3DRISM) equations is proposed. The effectiveness of the bridge for the aqueous solutions of the carbon nanomaterials is tested. In the paper two classes of systems are investigated: (i) infinitely diluted aqueous solutions of the Lennard ...

Analysis of a Wireless Power Transfer System Based on the Interaction of Very High Permittivity Dielectric Resonators with a Contained Aqueous Solution [PDF]
arXiv, 2020 An ab-initio analysis based on coupled mode theory (CMT) is applied to describe the interaction dynamics of high dielectric resonators (DRs) with its containing aqueous solution. We prove that the coupling mechanism is reciprocal. Such property is exploited to find closed form and accurate expressions of the coupling coefficient, the main factor ...
