The Role of Telemedicine in Emergency Department Triage and Patient Care: A Systematic Review.

Overcrowding in emergency departments (EDs) is a global challenge, leading to prolonged waiting times and adverse patient outcomes. Telemedicine has emerged as a promising solution, enabling remote consultation, triage, and real-time specialist input. Despite its growing application, limited systematic research exists on its specific role in ED triage and care.

Fluorometric detection of quinolones via AIE and FRET with terbium-doped carbon dots and copper nanoclusters.

Terbium and nitrogen co-doped carbon dots (Tb@N-CDs), combined with α-lipoic acid-functionalized copper nanoclusters (LA@CuNCs), were proposed for the ratiometric detection of quinolone (QA) antibiotics. In this system, Tb@N-CDs facilitate the aggregation of LA@CuNCs, enhancing its fluorescence emission at 670 nm via aggregation-induced emission enhancement (AIEE). Meanwhile, the fluorescence emission of Tb@N-CDs at 460 nm diminishes due to Förster resonance energy transfer (FRET).

Green synthesis of nickel-integrated chitosan-modified CeO nanocatalyst for the efficient hydrogenation of 4-NP and azo dyes.

This paper reports the green synthesis and characterization of nickel-integrated chitosan-modified cerium oxide (CHS-CeO@Ni) nanocatalyst aimed at the efficient hydrogenation of 4-nitrophenol (4-NP) and the reduction of azo dyes such as methyl orange (MO) and Congo red (CR). The CHS-CeO@Ni nanocatalyst was synthesized via a green method, where Arnebia benthamii plant extract was used as a reducing agent to deposit nickel nanoparticles onto the CHS-CeO nanocomposite. Results confirmed the successful integration of Ni into the CHS-CeO matrix, resulting in a highly crystalline, mesoporous structure with a substantial surface area of 78.

Developing a switch "OFF-ON" fluorescent probe for detection of melamine based on doubly-protected red emissive copper nanoclusters mediated by Hg ions.

Melamine, often used as an adulterant in infants' formula due to its high protein content, can be harmful when ingested in large amounts, leading to the formation of cyanurate-melamine co-crystals in infants and potentially causing kidney damage. In this study, we introduce a fluorescent method for the selective and reliable detection of melamine in milk and infants' formula. The fluorescent probe comprises copper nanoclusters (Cu NCs) functionalized with thiosalicylic acid (TSA) and polyvinylpyrrolidone (PVP) as double-protecting ligands.

High temperature photoluminescence dependence and energy migration of Tb-Incorporated KY(BO) phosphors.

This study investigates the structural and photoluminescence (PL) characteristics of Tb-incorporated KY(BO) (KYBO) phosphors synthesized via a microwave-assisted sol-gel technique. X-ray diffraction (XRD) and Rietveld refinement confirmed the formation of a pure hexagonal phase, with lattice expansion due to Tb³⁺ doping. PL studies revealed strong green emissions centered at 541 nm, attributed to the ⁵D₄ → ⁷F₅ transitions of Tb³⁺ ions, with the highest intensity observed at 5 wt% Tb³⁺.

Recent progress in metal oxide-based electrode materials for safe and sustainable variants of supercapacitors.

A significant amount of energy can be produced using renewable energy sources; however, storing massive amounts of energy poses a substantial obstacle to energy production. Economic crisis has led to rapid developments in electrochemical (EC) energy storage devices (EESDs), especially rechargeable batteries, fuel cells, and supercapacitors (SCs), which are effective for energy storage systems. Researchers have lately suggested that among the various EESDs, the SC is an effective alternate for energy storage due to the presence of the following characteristics: SCs offer high-power density (PD), improvable energy density (ED), fast charging/discharging, and good cyclic stability.
