Radiation‐Based 3D Dual‐Mode Thermal Management Devices: Advances in Active/Passive Switching for Energy‐Saving Applications

open access: yesSmall, EarlyView.
Heating and cooling energy demand account for nearly half of the global energy consumption. SH and RC offer sustainable, zero‐energy strategies, but single‐mode devices lack adaptability. 3D dual‐mode devices, exploiting axial, flipping, and bending deformations, provide reversible switching with dynamic or passive control, representing a promising ...

Functional Repurposing of Magnetic Nanoparticle‐Assisted Hyperthermia for Immune Cell Labelling and Tracking

open access: yesSmall Methods, EarlyView.
We propose mild‐MHT protocol for the quick internalization of magnetic nanoparticles (MNPs) by immune cells. The heat induced by MNPs under alternating magnetic field stimulate MNPs diffusion and cell membrane invagination, accelerating the cellular internalization of MNPs. ABSTRACT Immune cell therapies show promise in hematologic malignancies and are

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

open access: yesThe Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...
