Lead-free halide double perovskites (DPs) have become a research hotspot in the field of photoelectrons due to their unique optical properties and flexible compositional tuning. However, the luminescence of DPs exhibits thermal quenching at high temperatures, which severely affects their further application. Herein, we synthesized the rare earth Dy and transition metal Mn codoped CsNaYCl rare earth DPs and characterized the optical properties using temperature-dependent photoluminescence spectra and time-resolved photoluminescence decay profiles at different temperatures.

Directional Droplet Wetting on Cellulose Surfaces with Physical Modification.

Langmuir

January 2025

Department of Mechanical Engineering, The University of Melbourne, Parkville, Victoria 3010, Australia.

Directional wetting of liquids on solid surfaces is crucial for numerous applications. However, the impact of physical modifications on near-superhydrophilic cellulose has received limited attention as it is widely considered unfeasible. In this study, we present a previously unreported and simple but effective mechanism of directional wetting induced purely by physical modifications on pristine cellulose surfaces.

In vitro metabolism of seven arolyl-derived fentanyl-type new psychoactive substances.

Arch Toxicol

January 2025

School of Chemistry and Chemical Engineering, Guangxi University, Nanning, Guangxi, 530004, People's Republic of China.

Over the past decade, fentanyl-type new psychoactive substances (F-NPS) have emerged as the most representative synthetic opioids in third-generation drugs. These substances are characterized by their "low" fatal dose and parent drug levels in biological matrices, "fast" rates of derivatization and metabolism, and "many" derivatization sites and analogs. The low levels of parent fentanyl NPS in biological matrices complicate their detection, necessitating the use of characteristic metabolites as biomarkers for forensic analysis.

ChemSusChem

January 2025

State Key Laboratory of Featured Metal Materials and Life-cycle Safety for Composite Structures, School of Resource, Environments and Materials, Guangxi University, Nanning, 530004, China.

Lithium (Li) metal anodes (LMAs), which show a great potential in constructing high-specific-energy-density Li metal batteries (LMBs), have abstracted wide research interest. However, the generation of Li dendrites and the repeated change of volume upon Li plating/stripping severely block the practical commercialization of LMBs. Herein, the functional carbon fibers (CFs) decorated with ZnO embedded carbon cage (ZnO@C-d-CFs) were fabricated successfully by a two-step route including the in-situ growth of Zn-based metal organic frameworks (MOFs) and subsequent carbonization process, which enriched the lithiophilic sites of CFs host and improved Li kinetics of Li plating/stripping.
