Ultra-low luminescence of humid air and its possible role in negative air ion therapy.
One of the unresolved questions related to the mechanism of action of light negative air ions (reactive oxygen species) produced by air ionizers upon humans and animals is transmission of these short-living chemical species upon long distances from the place of their origin. We discovered the phenomenon which may probably resolve this problem. When a thin layer of water hydrating a hygroscopic ...
متن کاملControl of Respirable Particles in Indoor Air with Portable Negative Air Ion Generator
Portable negative air ion generator has been designed and tested. This device generates continuous emission of unipolar (negative) ions and it was evaluated by investigating its ability to remove respirable particles such as different smoke verities (mosquito coil smoke, cigarette smoke, petrol smoke) from indoor air environment. The experiment was carried out in closed glass container, decay r...
متن کاملInvolvement of the superoxide free radical ion in photosynthetic oxygen reduction.
Photosynthetic oxygen reduction by isolated chloroplast lamellar systems has been studied with the aid of superoxide dismutase. Two mechanisms of oxygen reduction by illuminated chloroplast lamellar systems can be differentiated: 1. In the presence of low potential electron acceptors like AQ or MV the superoxide free radical ion is the product of autooxidation of the reduced acceptor. Addition ...
متن کاملInfluence of air humidity and the distance from the source on negative air ion concentration in indoor air.
Although negative air ionizer is commonly used for indoor air cleaning, few studies examine the concentration gradient of negative air ion (NAI) in indoor environments. This study investigated the concentration gradient of NAI at various relative humidities and distances form the source in indoor air. The NAI was generated by single-electrode negative electric discharge; the discharge was kept ...
متن کاملEffects of a Weak Transverse Magnetic Field and a Spatial Potential on Negative Ion Transport in Negative Ion Sources
The effects of the weak magnetic field on the negative ion ( ) extraction in a negative ion source have been studied by means of a two-dimensional electrostatic particle simulation. A particle-in-cell (PIC) model is used which simulates the motion of the charged particles in their self-consistent electric field. Since most electrons are magnetized by the weak magnetic field, it is shown that mo...
