Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

Review of Multi-Physics Modeling on the Active Magnetic Regenerative Refrigeration

Mathematical and Computational Applications, 2021
Compared to conventional vapor-compression refrigeration systems, magnetic refrigeration is a promising and potential alternative technology. The magnetocaloric effect (MCE) is used to produce heat and cold sources through a magnetocaloric material (MCM).

An ‘Empty’ [Fe16] Cage and its Transformation into [Fe17] and [Fe30]

Small, EarlyView.
Polymetallic clusters of FeIII constructed without organic bridging ligands are an emerging class of molecules with structures akin to iron oxide minerals, possessing large spin ground states and/or displaying spin frustration effects. All previous examples, [Fe8], [Fe17], [Fe30] and [Fe34], have been isolated from pyridine or analogous heterocyclic ...

Modeling the Maximum Magnetic Entropy Change of Doped Manganite Using a Grid Search-Based Extreme Learning Machine and Hybrid Gravitational Search-Based Support Vector Regression

Crystals, 2020
The thermal response of a magnetic solid to an applied magnetic field constitutes magnetocaloric effect. The maximum magnetic entropy change (MMEC) is one of the quantitative parameters characterizing this effect, while the magnetic solids exhibiting ...

Magnetocaloric effect in La0.75Sr0.25MnO3 manganite [PDF]

Journal of Magnetism and Magnetic Materials, 2010
Abstract The polycrystalline manganite La0.75Sr0.25MnO3 prepared by an alternative carbonate precipitation route reveals the rhombohedral perovskite structure. Magnetization isotherms measured up to 2 T are used to determine Curie temperature of 332 K by means of Arrott plot. Maximum of magnetic entropy change is found at Curie temperature.

Magnetothermal‐responsive drug release bone cement based on EGFR‐mutated lung cancer bone metastases

VIEW, EarlyView.
A novel magnetothermal‐responsive bone cement was developed by integrating PMMA/CPC/Osimertinib matrix with Fe3O4@SiO2@Zol nanomaterials. This dual‐drug system achieves controlled release, combining excellent mechanical properties with potent anti‐tumor activity and bone regulation for treating EGFR‐mutated LC‐BoM.

Magnetocaloric Properties of Centered Molecular Quantum Spin Systems

physica status solidi (a), Volume 223, Issue 19, 6 October 2026.
Sub‐Kelvin temperatures are needed for quantum computers and other quantum devices. Refrigeration employing magnetic materials is able to achieve the necessary very low temperatures of a few millikelvins above absolute zero. In this article, we investigate the magnetocaloric properties of a class of centered magnetic molecules and study their ...

New design of La(Fe, Co, Si)13 magnetocaloric composites using Gd as a binder

Journal of Materials Research and Technology
We propose a new type of magnetocaloric composite that excludes the conventional use of non-magnetocaloric materials as the binder. Spark plasma sintering was adopted to make a fully dense La(Fe, Co, Si)13/Gd composite at low temperatures (450–600 °C ...
