A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

open access: yesRare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

To Dye or Not to Dye: Unraveling the Impact of Surface Chemistry on Cerium Oxide Nanoparticles–Cell Interactions

open access: yesSmall Science, EarlyView.
Fluorescent dye labeling enables nanoparticle imaging but may subtly alter their surface chemistry and biological behavior. This study compares dye‐labeled and unlabeled cerium oxide nanozymes, revealing changes in cellular uptake kinetics without affecting their final intracellular fate. Combined fluorescence and label‐free electron microscopy imaging

Probing Viscoelasticity of Polymeric Coatings Using Nonlinear Dynamic Atomic Force Microscopy

open access: yesSmall Methods, EarlyView.
For soft materials it is essential to characterize both the elastic and viscous material properties. Using an atomic force microscope, the hardening nonlinearity induced by a tip‐sample contact and bifurcation points can be used to separately estimate the visco‐ and elastic parts of the tip‐sample interaction force.

Study of Heat Transfer Simulation Method for Magnetic Hyperthermia Considering Heat Generation Characteristics of Thermo‐Sensitive Magnetic Particle

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The purpose of this paper is to establish a heat transfer simulation method for magnetic hyperthermia that incorporates the heat generation characteristics of low curie point thermo‐sensitive magnetic particles and their relative position to a Drive coil that applies the magnetic field.

Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Thickness Calculation of Pigment Layers and Gold Leaves Using XRF and MA‐XRF Data

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT In this work, XRF and MA‐XRF data were used to estimate the thickness of Chromium Oxide (Cr₂O₃) pigment and gold leaf applied over Lead White (2PbCO3.Pb(OH)2). The thickness determination was based on the differential attenuation of the Pb‐Lα and Pb‐Lβ characteristic X‐rays, which allows correlating the overlying material layer with the Pb(Lα ...

Leaf trichomes can alleviate water deficit stress and maintain diurnal photosynthesis by increasing leaf wetness and water absorption in Metrosideros polymorpha

open access: yesPlant Species Biology, EarlyView.
Leaf trichomes are often considered a key trait contributing to drought tolerance by increasing leaf wetness and enhancing foliar water uptake. However, their function has not been examined across a wide range of environmental conditions. Our field observations and manipulation experiments on Metrosideros polymorph—a species with trichomes that vary ...
