The main challenge for gas storage and separation in nanoporous materials is that many molecules of interest adsorb too weakly to be effectively retained. Instead of synthetically modifying the internal surface structure of the entire bulk-as is typically done to enhance adsorption-here we show that post exposure of a prototypical porous metal-organic framework to ethylenediamine can effectivel...

BACKGROUND Many studies have examined the association between air pollutants (including sulfur dioxide [SO2], carbon monoxide [CO], nitrogen dioxide [NO2], nitric oxide [NO], ozone [O3], and particulate matter < 10 μm [PM10]) and lung cancer. However, data from previous studies on pathological cell types were limited, especially for SO2 exposure. We aimed to explore the association between SO2 ...

Sulfur dioxide (SO2) is a problematic inhalable air pollutant in areas of widespread industrialization, not only in the United States but also in countries undergoing rapid industrialization, such as China, and it can be a potential trigger factor for asthma exacerbations. It is known that asthmatics are sensitive to the effects of SO2; however, the basis of this enhanced sensitivity remains in...

The prediction of regional sulfur dioxide (SO2) emission of thermal power belongs to gray system which has small amounts of samples and little information, so a appropriate forecasting method is essential. Based on thermal power industry SO2 emission data from state department authorities, considering the main factors of China's thermal power industry SO2 predicted emission, we established a co...

Sulfur dioxide (SO2), a typical gaseous compound found in the atmosphere, corrodes metals, particularly outdoors. When SO2 adsorbs on the surface electrolyte, it easily dissolves, resulting in the formation of protons (H+) and bisulfite ions (HSO3). The former reduces the pH of the surface electrolyte, which promotes metal dissolution. Silver and copper are commonly used in the electronic compo...

OBJECTIVE To examine the effect on hospital presentations for asthma of brief exposures to sulphur dioxide (SO2) (within the range 0-8700 micrograms/m3) emanating from two point sources in a remote rural city of 25,000 people. METHODS A time series analysis of SO2 concentrations and hospital presentations for asthma was undertaken at Mount Isa where SO2 is released into the atmosphere by a co...

This work examines the process of detecting and quantifying volcanic SO2 plumes using the Airborne Hyperspectral Infrared Imager (AHI) developed by the University of Hawaii. AHI was flown over Pu'u'O'o Vent of Kilauea Volcano in Hawaii to collect data on SO2 plumes. AHI is a LWIR pushbroom imager sensitive to the 7.5 11.5 μ region. Spectral analysis and mapping tools were used to identify and c...

SO2emissions, the largest sourceof anthropogenic aerosols, can respond rapidly toeconomic and policy driven changes. However, bottom-up SO2 inventories have inherent limitations owing to 24–48months latency and lack of month-to-month variation in emissions (especially in developing countries). This study develops a new approach that integrates OzoneMonitoring Instrument (OMI) SO2 satellitemeasu...
