Although the particle phase state is an important property, there scant information on it, especially, for real-world aerosols. To explore of fine mode aerosols (PM2.5) in two megacities, Seoul and Beijing, we collected PM2.5 filter samples daily from Dec 2020 to Jan 2021. Using optical microscopy combined with poke-and-flow technique, states bulk as a function relative humidity (RH) were determined compared ambient RH ranges cities. was found be liquid semisolid but mostly solid Beijing....
In this work, a new metal-to-metal charge transfer (MMCT) heterogeneous catalyst (Nb–O–Mo) was synthesized by chemical grafting method under an inert atmosphere. The activity of the covalently anchored oxo-bridged Nb–O–Mo estimated for decolorization Rh B, congo red, and crystal violet dyes in aqueous solution fluorescent light. characterized via X-ray diffraction, scanning electron microscopy with energy-dispersive spectrometer, Fourier-transform infrared, FT-Raman. catalytic evaluated from...
The growing interest in metal–organic frameworks (MOFs) both industrial and scientific circles has increased the last twenty years, owing to their crystallinity, structural versatility, controlled porosity. In this study, we present three novel MOFs obtained from 1, 3, 5-tris (1H-benzo[d]imidazole-2-yl) benzene (TIBM) organic linker. formed TIBM crystal powders were characterized by scanning electron microscopy (SEM) estimate morphology of particles, powder X-ray diffraction (XRD) confirm...
Atmospheric aerosol particles are complex mixtures having various physicochemical properties. To predict the role and characteristics of such in air pollution related atmospheric chemistry, our knowledge number types phases should be improved. However, most studies on phase behavior have been conducted laboratory not used real-world particles. In this study, using a combination optical microscopy poke-and-flow technique, we investigated actual particulate matter < 2.5 µm (PM )...
The morphology and phase state are critical physical properties of aerosol particles. However, studies related to the analysis these primarily focus on laboratory experiments, real particles limited. Herein, fine particulate matter (PM 2.5 ) filter samples were obtained investigate compare ambient in South Korea. PM collected summer June 2021 from two different environments: Seoul (urban) Seosan (coastal-rural). Optical microscopy was combined with poke-and-flow technique determine as a...
This study aimed to develop a one-pot eco-friendly approach for synthesizing K+ doped HKUST-1 (K-HKUST-1) using water-soluble salt of potassium trimesate and various nonconventional heating methods. K-HKUST-1 synthesized via ultrasonication-45 °C showed the highest CO2 adsorption capacity (6.19 mmol/g) CO2/N2 selectivity (24.92) at 298K 1 bar stability under atmospheric conditions improved as compared parent MOF. Density functional theory (DFT) simulation demonstrated that improvement in...
