A cotton textile dried with various hygroscopic salts then contaminated with Staphylococcus epidermidis and dried again, showed remarkable reduction in viable bacterial cells. Of the salts investigated, sodium acetate was found to have the greatest antibacterial effect. Calcium chloride, magnesium chloride and magnesium sulfate, also showed some antibacterial effect. For sodium acetate, drying ...
We have studied the effect of gaseous pollutants on fog droplet growth in heavily polluted air using a model that describes time-dependent sulfate production in the liquid phase and thermodynamical equilibrium between the droplets and the gas phase. Our research indicates that the oxidation of SO2 to sulfate has a significant effect on fog droplet growth especially when hygroscopic trace gases,...
Discontinuities in apparent hygroscopicity below and above water saturation have been observed for organic and mixed organic–inorganic aerosol particles in both laboratory studies and in the ambient atmosphere. However, uncertainty remains regarding the factors that contribute to observations of low hygroscopic growth below water saturation but enhanced cloud condensation nuclei (CCN) activity ...
Visibility degradation is a pervasive and urgent environmental problem in China. The occurrence of low visibility events is frequent in the North China Plain, where the aerosol loading is quite high and aerosols are strongly hygroscopic. A parameterization of light extinction (Kex) for low visibilities on hazy days is proposed in this paper, based on visibility, relative humidity (RH), aerosol ...
For fiber reinforced resin matrix composites, void is a common defect which can seriously deteriorate the properties of composite parts. Voids form and grow during composite fabrication, so the processing parameters must be carefully controlled to avoid this defect. In hot melt prepreg/autoclave process, hygroscopic water absorbed by prepreg is believed to be the main source of voids, especiall...
