Summary: This research successfully developed a fluorescent sensor based on dual-emitting lanthanide metal-organic frameworks for the quantitative detection of various fluoroquinolone antibiotics. The sensor exhibited characteristic color variations towards nine fluoroquinolones, enabling discriminative detection of multiple antibiotics. A polynomial surface fitting process was developed for quantitative analysis by correlating the coordinates of the color-coding map with target concentrations. Additionally, a smartphone-enabled sensing system was demonstrated for on-site imaging analysis of antibiotics.

Summary: We demonstrate an AC-driven light emitting capacitor that can change the color of the emission spectra by adjusting the applied AC frequency. The device has a simple MOS capacitor structure with an organic emissive layer, allowing for easy fabrication. The emission of low energy dyes dominates at low frequency, while the emission of high energy dyes from the host matrix dominates at high frequency. This color tunable device has potential applications in future full-color displays and lighting.

Summary: Current commercial white LEDs are typically composed of blue LED chips and yellow phosphors, resulting in cool white-light emissions with low color rendering index due to the lack of red component. There is a need to discover new blue-light-excitable yellow-emitting phosphors with enhanced red emissions for producing high color-quality white LEDs. The novel CaGd2HfScAl3O12:Ce3+ garnet phosphor shows promising potential as a color converter in high-color-quality phosphor-converted white LEDs.

Summary: By selecting a bisphosphonic ligand H4L and a coligand oxalate, three isostructural lanthanide metal-organic frameworks (Ln-MOFs) with a 2D layer structure were synthesized. By tuning the molar ratio of different lanthanide ions, doped Ln-MOFs with variable luminescent colors were obtained, which can be potentially used in anti-counterfeiting applications. Moreover, one of the Ln-MOFs (3) showed good thermal, water, and pH stabilities, and served as a selective and reusable luminescent sensor for sulfamethazine (SMZ).

Summary: Designing materials for selective recovery of precious metals is critical in response to the economic and environmental concerns caused by electronic waste outbreaks. In this study, high-performance hybrid materials (MCNTs) based on hexaaminobenzene metal-organic framework (HAB-MOF) and carbon nano-tube (CNT) sponge were introduced for selective recovery of Au(III) and Pd(II). The synthesized 30-MCNT demonstrated the highest adsorption capacity for Au(III) and Pd(II) among all reported MOFs, making it a benchmark material in the MOF family. The material showed high selectivity and excellent recovery and recycling properties, making it a potential candidate for industrial applications in precious metal recovery.

Summary: Al-NDC@GO composites were successfully prepared via the reaction of 1,4-naphthalene dicarboxylic acid (1,4-H2NDC), Al(NO3)(3)center dot 9H(2)O, and graphene oxide (GO) in water. The composites exhibited remarkable adsorption capacity for pyridine, quinoline, and indole in the liquid phase, high adsorptive selectivity in the presence of naphthalene and benzene, and satisfactory recyclability. The excellent adsorption performance of the composites is attributed to the high surface area, porosity, and the presence of unsaturated metal sites and excessive oxygen groups on exfoliated layers of GO sheets.

Summary: It is crucial to develop a sustained-release pralidoxime chloride (2-PAM) drug system that can target the brain for the treatment of neurotoxicant poisoning. In this study, thiamine (VB1) was incorporated onto the surface of MIL-101-NH2(Fe) nanoparticles, which can bind to the thiamine transporter on the blood-brain barrier. Pralidoxime chloride was loaded within the composite, resulting in a composite drug (2-PAM@VB1-MIL-101-NH2(Fe)) with a loading capacity of 14.8% (wt). The composite drug showed a pH-dependent drug release rate, with a maximum release rate of 77.5% at pH 4. Furthermore, the composite drug exhibited sustained release and stable reactivation of poisoned acetylcholinesterase (AChE) in mice, with a reactivation rate of 42.7% in ocular blood samples at 72 h. Cross-blood-brain-barrier penetration and AChE activity restoration in the brain of poisoned mice were observed with the composite drug. It is anticipated that this composite drug can serve as a stable therapeutic option with brain targeting and prolonged drug release properties for nerve agent intoxication in the middle and late stages of treatment.
