The objective of this study is to provide fundamental data related size-based characteristics bioaerosol distributed in the general hospital. Measurement sites are main lobby, ICU, surgical ward and biomedical laboratory total five times were sampled with six-stage cascade impactor. Mean concentrations airborne bacteria fungi highest lobby as followed by an order ward, ICU laboratory. predominant genera identified hospital Staphylococcus spp. (50%), Micrococcus (15-20%), Corynebacterium...
UiO-66(Zr) has been widely used for many applications due to its high surface area and excellent chemical thermal stabilities. Conventionally, prepared in an autoclave by solvothermal synthesis, which requires a lengthy reaction time (typically 24 h) while only producing small amount of product. In this work, larger quantity was rapidly produced continuous tubular reactor under microwave irradiation. The metal salt organic linker precursor solutions were continuously introduced into the...
The aim of this study was to identify the characteristics an α-FeOOH based composite for removal hydrogen sulfide in room temperature gas streams. supported on commercial-activated carbon powder avoid agglomeration problem fabrication. prepared by using FeCl3 solution (as Fe precursor) and NH4HCO3 a pH control). formation confirmed observing α-Fe2O3 under hydrothermal condition. results experiment indicate that activated functioned effectively as support material composite, providing large...
Odor-causing substances are generated by various emission sources in urban areas. Recently, urbanization has greatly increased the density of odor facilities, implying identification odorants source is challenging. Identifying multifactorial, and a machine learning approach considered useful for these complicated matters. The objectives this study were to propose method using learning-based classification models identify We collected 34,539 data points regarding quantitative 22 compounds...
Trichloroethylene (TCE) is widely used in various industrial applications, leading to significant environmental and public health concerns due its toxicity persistence. Current nonthermal liquid-phase TCE treatment methods, including electrochemical processes, typically produce liquid byproducts that require additional separation steps, limiting their efficiency. To overcome these challenges, this study introduces an innovative approach for the direct conversion of gas into less harmful...
Cu‐doped MOF‐235 particles with various Cu concentrations were successfully prepared using the solvothermal method and investigated for degradation of methylene blue (MB) under visible light irradiation. The structural properties samples affected by concentrations. particle size, surface area, pore volume sample decreased gradually increasing amount. photocatalytic MB indicated that outperformed pure commercial TiO 2 due to presence + 2+ species suppress electron–hole recombination. After 8...
Electrochemical methods have been widely used to remove gaseous pollutants that are dissolved in liquids. However, there no significant attempt made their gas state, especially through electrochemical method. In this study, we attempted acetaldehyde (AA) electro-oxidation using an Ag-Hg bimetallic catalyst coated on a Ni foam electrode at gas–solid interface. The interface was induced by semi-solid agar gel membrane-divided electrolytic cell. We confirmed the formation of X-ray photoelectron...
The exposure level and distribution characteristics of airborne bacteria fungi were assessed in the workers' activity areas (station office, bedroom, ticket office driver's seat) passengers' precinct, inside passenger carriage, platform) Seoul metropolitan subway. Among investigated areas, levels bedroom station precincts relatively high. No significant difference was found concentration between underground above ground genera identified all subway with a 5% or greater detection rate...
We describe the utility of a standardized index (Z-score) in quantitative EEG (QEEG) capable when referenced to resting-state, sex- and age-differentiated QEEG normative database (ISB-NormDB). Our ISB-NormDB comprises data for 1,289 subjects (553 males, 736 females) ages 4.5 81 years that met strict criteria. A de-noising process allowed stratification based on variability between normal healthy men women at various age ranges. The set is stratified by sex provides unique, highly accurate...
Abstract Trickle-bed air biofilters (TBABs) are suitable for treating volatile organic compounds (VOCs) at a significantly high practical loading because of their controlled environmental conditions. The application TBAB styrene-contaminated under periodic backwashing and cyclical nonuse periods styrene 0.64–3.17 kg chemical oxygen demand (COD)/m3·day was the main focus this study. Consistent long-term efficient performance strongly depended on biomass control. A in situ upflow with nutrient...
