Neodymium‐Doped Nanocrystals for Sensing Cellular Temperature at the Nanoscale

open access: yesAdvanced Optical Materials, EarlyView.
Neodymium‐doped NaYF4 nanocrystals are engineered as bright, biocompatible nanothermometers for intracellular temperature mapping. Their ratiometric near‐infrared emission enables highly sensitive, nanoscale thermal readouts in living cells. Combined with gold nanostars for photothermal therapy, they reveal pronounced subcellular heating heterogeneity ...

Bayesian‐Optimized Dual‐Mode Luminescence‐Based Optical Thermometry Enabled by Negative Thermal Expansion in Lu2(MoO4)3:Yb–Er–Tm Phosphor

open access: yesAdvanced Optical Materials, EarlyView.
A Bayesian optimization framework identifies the ideal composition for Lu2(MoO4)3:Yb–Er–Tm phosphors with minimal experimental trials. By leveraging the host's negative thermal expansion, the material achieves remarkable thermal quenching compensation.

Synergistic Ligand Engineering Suppresses Dye Aggregation Quenching and Photobleaching in Lanthanide Upconversion Nanoparticles

open access: yesAggregate
Near‐infrared cyanine dyes are widely employed for sensitizing lanthanide upconversion luminescence (UCL), but generally suffer from aggregation‐caused quenching (ACQ) and photobleaching. Herein, we report a ligand engineering strategy utilizing pyridine‐

Synthesis, Characterization, Electrochemistry, Photoluminescence and Magnetic Properties of a Dinuclear Erbium(III)-Containing Monolacunary Dawson-Type Tungstophosphate: [{Er(H2O)(CH3COO)(P2W17O61)}2]16−

open access: yesMolecules, 2020
Reaction of the trilacunary Wells−Dawson anion {α-P2W15O56}12− with ErIII ion in a 1 M LiOAc/HOAc buffer (pH 4.8) solution produces a dinuclear erbium(III) substituted sandwich-type structure [{Er(H2O)(CH3COO)(P2W17O61)}2]16− (1).

Molecular neurochemistry of the lanthanides [PDF]

open access: yesSynapse, 2019
AbstractLanthanides, once termed rare‐earth elements, are not as sparce in the environment as their traditional name suggests. Mean litospheric concentrations are in fact comparable to the physiologically fundamental elements such as iodine, cobalt, and selenium.

Circularly Polarized Red‐NIR Emission With High Dissymmetry Factor From Achiral [Mo6I8(OCOC2F5)6]2− Cluster Anion Embedded in a Bent‐Core Liquid Crystal Host

open access: yesAdvanced Optical Materials, EarlyView.
Associating a chiral bent core liquid crystal molecule, that self‐assembles into helical nanofilaments, with an achiral red‐NIR phosphorescent octahedral molybdenum cluster produces a hybrid material exhibiting efficient red‐NIR circularly polarized emission under UV excitation.

Antenna Effect in Halogen‐Containing ZnSm Coordination Compounds: Utilizing Colorimetry for a Room‐Temperature Tunable Ratiometric Molecular Thermometer

open access: yesAdvanced Science, EarlyView.
The ZnSm‐Cl dinuclear molecular complex was synthesized through a simple one‐pot method. ZnL and Sm3+ exhibit complementary temperature‐dependent emission As the temperature increases, a noticeable color difference of ZnSm‐Cl can be observed within the room temperature range of 253‐333 K.

Weathered granites and soils harbour microbes with lanthanide-dependent methylotrophic enzymes

open access: yesBMC Biology
Background Prior to soil formation, phosphate liberated by rock weathering is often sequestered into highly insoluble lanthanide phosphate minerals. Dissolution of these minerals releases phosphate and lanthanides to the biosphere.

A New Customizable Surfactant LLPS Strategy for Sustainable and Highly Efficient Radioactive Metal Ion Separation

open access: yesAdvanced Science, EarlyView.
A diluent‐free, customizable liquid–liquid phase separation (LLPS) platform enables highly efficient radioactive metal ion extraction and stripping. By encapsulating hydrophobic extractants into an ionic surfactant‐rich condensed phase, this LLPS system leverages synergistic electrostatic and coordination interactions.
