AbstractRapid industrialization has intensified air pollution, particularly in areas where industrial and residential zones overlap. This study analyzed emissions from the Yeosu Industrial Complex, South Korea, a major source of volatile organic compounds (VOCs), methane (CH₄), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and particulate matter (PM). Advanced remote and in situ optical techniques—solar occultation flux (SOF), sky differential optical absorption spectroscopy (SkyDOAS), mobile extraction Fourier transform infrared spectrometry (MeFTIR), sniffer 4D, and LiDAR—were employed to assess spatial pollutant distribution across five zones. Zones A and B exhibited the highest emissions (8,622,468 kg/year and 21,826,416 kg/year), largely due to petrochemical and rubber manufacturing activities. Pollutants, particularly alkanes, NO₂, and SO₂, were highest during southeasterly winds, which transported emissions to nearby residential areas, increasing health risks. A comparison with the Clean Air Policy Support System (CAPSS) inventory highlighted underestimations of VOC emissions in national records. Discrepancies in PM₁₀ measurements by Sniffer 4D (2–6 µg/m3) and LiDAR (14–15 µg/m3) in zone A emphasized the importance of integrating measurement methods to improve emission accuracy. This study demonstrates the potential of combining mobile and remote sensing techniques to enhance emission inventories and provides critical insights for targeted air quality management in industrial-residential interfaces.

The contents of fluoride in drinking water should be limited to a safe range. Hence, design and development of a simple and efficient technology for adsorption and detection of fluoride is urgently required. We presented a curcumin in situ grafted MOF magnetic material (Fe₃O₄/MOF-Cur) for dual-functionalized applications of fluoride detection and adsorption. Owing to the electrostatic interaction, ligand exchange at the metal sites and boron-fluorine complexation, the adsorption capacity of Fe₃O₄/MOF-Cur for fluoride is 99.92 mg/g, and the detection limit is 1.17 μM. The fluoride adsorption behavior on different active units was further visualized by theoretical calculations. Favorable stability (79.52 mg/g after 5 adsorption-desorption cycles and insignificant change of fluorescence intensity within 30 days), mild reaction conditions (pH = 3-5) and excellent anti-interference ability promote the application of Fe₃O₄/MOF-Cur in real samples. Finally, the paramagnetic properties (29 emu/g) allow for easy recovery from water. These findings deepen the understanding on the design and development of dual-functionalized MOF materials, and prove the application potential of Fe₃O₄/MOF-Cur for the remediation of fluoride-related environmental pollution.

Self-assembled nanoprobes have emerged as an advanced cancer treatment, offering a unified platform that integrates both diagnostic and therapeutic capabilities.This paper highlights recent advancements in self-assembled nanoprobes designed for cancer phototheranostics, combining photodynamic therapy (PDT) and/or photothermal therapy (PTT) with imaging such as fluorescence imaging (FI) and/or photoacoustic imaging (PAI) for precise tumor targeting.Combinations with chemotherapy (CMT), chemodynamic therapy (CDT), surgical therapy (ST), and photoimmunotherapy (PIT) were also considered.By leveraging key features of the tumor microenvironment, such as acidic condition, high glutathione levels, and hypoxia, these nanoprobes facilitate stimuli-responsive activation, improving therapeutic precision while reducing unintended side effects.Nanoprobes are based on various types of chromophores including porphyrin, cyanine, xanthene, BODIPY derivatives, and aggregation-induced emission luminogens.These designs exhibit an improved photothermal conversion efficiency (PCE), enhanced reactive oxygen species (ROS) generation, and compatibility with multimodal imaging such as near-IR FI and PAI.This report provides an overview of the design principles, activation mechanisms, and therapeutic efficacy of these advanced nanoprobes, emphasizing their potential for cancer phototheranostics.
