Decoupled tin-silver batteries with long cycle life and power output stability based on dendrite-free tin anode and halide insertion cathode chemistry.

Conventional Ag-Zn batteries have historically faced the challenge of poor cycling stability, rooting in issues associated with Ag cathode dissolution and Zn anode dendrites. Herein, we present a pioneering decoupled Sn-Ag cell, which features two chambers separated by a cation-exchange membrane, containing a dendrite-free Sn metal anode immersed in an alkaline anolyte, and an Ag nanowires/carbon nanotube 3D thick-network cathode in a neutral catholyte. Benefiting from the achieved high electroplating/stripping stability of the metallic Sn anode in the alkaline electrolyte and the electrochemical reversibility of the Ag/AgCl cathode redox couple in the neutral electrolyte, the assembled decoupled Sn-Ag cell demonstrates superior cycling stability, retaining 82.

Thermal properties of nanofluids using hydrophilic and hydrophobic LiYF:Yb/Er upconverting nanoparticles.

Luminescent nanoparticles have shown great potential for thermal sensing in bio-applications. Nonetheless, these materials lack water dispersibility that can be overcome by modifying their surface properties with water dispersible molecules such as cysteine. Herein, we employ LiYF:Er/Yb upconverting nanoparticles (UCNPs) capped with oleate or modified with cysteine dispersed in cyclohexane or in water, respectively, as thermal probes.

Exploring the potential of Eu and Mn activated LaAlO phosphors as red and far-red emitters for horticulture lighting.

The development of efficient red and far-red emitters, for efficient plant absorption in the Photosynthetically Active Radiation (PAR) region, holds significance in contemporary plant growth control. This study focuses on the synthesis and characterization of LaAlO as a host material, doped with Eu and Mn ions, using a solid-state reaction method. The investigation encompasses the creation and analysis of both single-doped and co-doped samples, employing techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL) spectroscopy.

Temperature sensing in Tb/Eu-based tetranuclear silsesquioxane cages with tunable emission.

New luminescent cage-like tetranuclear silsesquioxanes [NEt][(PhSiO)(TbEu)(NO)(OH)(EtOH)(HO)]·4(EtOH) (1) and [NEt][(PhSiO)(TbEu)(NO)(EtOH)(MeCN)]·4(MeCN) (2) present a tunable thermosensitive Tb-to-Eu energy transfer driven by Tb and Eu emission and may be used as temperature sensors operating in the range 41-100 °C with excellent linearity ( = 0.9990) and repeatability (>95%). The thermometer performance was evidenced by the maximum relative sensitivity of 0.
