A non-thermal plasma, air purification device (PlasmaShield®, MD250, Keswick, SA, Australia), was investigated using spatially resolved optical emission spectroscopy. The spectra were measured with two spatial dimensions to analyze and identify the transition lines of excited NO–? (A2?–X2?), N2 (C3?–B3?), N2+ (B2?–X2?) systems. band at 337 316 nm used determine vibrational temperature molecules...

The semiconducting transition metal oxide TiO2 is a rather cheap and non-toxic material with superior photocatalytic properties. thin films nanoparticles are known to have antibacterial, antiviral, antifungal, antialgal, self, water, air-cleaning properties under UV or sun light irradiation. Based on these excellent qualities, titania holds great promises in various fields of applications. vast...

There is growing interest in air quality and purification, due to current high pollution levels, their effects on human health, implications for urban economies. Since the improvement of carries important economic value, air-related benefits have been evaluated monetarily from two perspectives: first relates improvements, while second values purification as an ecosystem function. This research ...

Few empirical studies have examined the simultaneous effects of window opening and indoor plants on air characteristics. This study compared four variables, day/night, status, plant distance, number plants, characteristics in a room at basement via experiments. was because perform photosynthesis during day, which produces O2 absorbs CO2, whereas they usually produce only CO2 night. Moreover, hi...

Bubble Stability An acoustically levitated bubble can gain permanent stability due to the suppression of drainage by sound field and prevention capillary waves via liquid compensation. The everlasting shows a significantly enhanced particle adsorption ability, which shed light on development novel air-purification techniques without consuming any solid filters. More details be found in article ...

The article proposes the improvement of adsorption and absorption plants for recovery naphtha vapors through use a sulfur compounds purification unit. This unit allows you to remove environmentally hazardous components from vapors, which adversely affect filters, without increasing temperature significant pressure drop gas-air mixture. relevance study is due fact that marine terminals are objec...
