Microwave assisted nanofibrous air filtration for disinfection of bioaerosols

Airborne biological agents, albeit intentionally released or naturally occurring, pose one of the biggest threats to public health and security. In this study, a microwave assisted nanofibrous air filtration system was developed to disinfect air containing airborne pathogens. Aerosolized E. coli vegetative cells and B. subtilis endospores, as benign surrogates of pathogens, were collected on nanofibrous filters and treated by microwave irradiation. Both static on-filter and dynamic in-flight tests were carried out. Results showed that E. coli cells were efficiently disinfected in both static and in-flight tests, whereas B. subtilis endospores were more resistant to this treatment. Microwave power level was found to be the major factor determining the effectiveness of disinfection. Both thermal and non-thermal effects of microwave irradiation contributed to the disinfection. Reducing flow velocity to decrease heat loss yielded higher disinfection efficiency.     

Applications of Plasma-Activated Water in Dentistry: A Review

The activation of water by non-thermal plasma creates a liquid with active constituents referred to as plasma-activated water (PAW). Due to its active constituents, PAW may play an important role in different fields, such as agriculture, the food industry and healthcare. Plasma liquid technology has received attention in recent years due to its versatility and good potential, mainly focused on different health care purposes. This interest has extended to dentistry, since the use of a plasma–liquid technology could bring clinical advantages, compared to direct application of non-thermal atmospheric pressure plasmas (NTAPPs). The aim of this paper is to discuss the applicability of PAW in different areas of dentistry, according to the published literature about NTAPPs and plasma–liquid technology. The direct and indirect application of NTAPPs are presented in the introduction. Posteriorly, the main reactors for generating PAW and its active constituents with a role in biomedical applications are specified, followed by a section that discusses, in detail, the use of PAW as a tool for different oral diseases.

Recent Developments in Food and Agricultural uses of Ozone as an Antimicrobial Agent-Food Packaging Film Sterilizing Machine using Ozone

Recent food putrefaction with new strains of microorganisms, such as Lactic acid bacteria and disinfectant-resistant strains of gram-negative bacteria, mold, yeast have increased interest in exploring different disinfection techniques for food sanitation. In Japan, food processing companies consider Lactic acid bacteria and gram-negative bacteria, mold, yeast, to be of greatest concern because of the severity and number of food putrefaction they cause. We supplied a laboratory machine that sterilizes for food packaging film and preformed cups using ozonated water and ozone gas. UV-ray sterilizing can be used for support. Ozone should be useful in reducing the degree of microbial contamination caused by inadequate disinfection against new resistant strains. There is growing tendency to use ozone in food industry as an effective means of disinfection without any additives. Many types application equipment have been developed. Based on the properties of ozone as a strong germicidal agent, conversion of factories to use ozone for sterilization of food packaging film is being implemented.     

Influence of water vapour on plasma/photocatalytic oxidation efficiency of acetylene

Non-thermal plasma as well as photocatalysis is intensively investigated for volatile organic compounds (VOCs) oxidation. Their association exhibits high performances for air pollutant removal and mineralization. Nevertheless, numerous experimental investigations are performed under dry conditions, or on very short range of water vapour amounts. This article aims at determining the influence of water vapour on the oxidation efficiency of (i) photocatalysis, (ii) non-thermal plasma, and (iii) their association. The amount of water vapour investigated in dry conditions ranges from 0 ppm to 23,000 ppm. Acetylene has been selected as a model pollutant. The presence of water vapour in the gas stream induces a strong decrease in the photocatalytic oxidation of acetylene. The mineralization process is modified. The efficiency of acetylene removal by non-thermal plasma decreases regularly with the water vapour amount. Nevertheless, the presence of water vapour improves significantly the selectivity of carbon dioxide. The same tendency is reported for plasma/photocatalysis association. Those results are interpreted in terms of oxidative species modification due to the presence of water. Moreover, the investigation of water vapour contribution into oxidative processes improves the understanding of plasma/photocatalytic association mechanisms.     

Low-Temperature Plasma-Assisted Nitrogen Fixation for Corn Plant Growth and Development

Nitrogen fixation is crucial for plants as it is utilized for the biosynthesis of almost all biomolecules. Most of our atmosphere consists of nitrogen, but plants cannot straightforwardly assimilate this from the air, and natural nitrogen fixation is inadequate to meet the extreme necessities of global nutrition. In this study, nitrogen fixation in water was achieved by an AC-driven non-thermal atmospheric pressure nitrogen plasma jet. In addition, Mg, Al, or Zn was immersed in the water, which neutralized the plasma-treated water and increased the rate of nitrogen reduction to ammonia due to the additional hydrogen generated by the reaction between the plasma-generated acid and metal. The effect of the plasma-activated water, with and without metal ions, on germination and growth in corn plants (Zea Mays) was investigated. The germination rate was found to be higher with plasma-treated water and more efficient in the presence of metal ions. Stem lengths and germination rates were significantly increased with respect to those produced by DI water irrigation. The plants responded to the abundance of nitrogen by producing intensely green leaves because of their increased chlorophyll and protein contents. Based on this report, non-thermal plasma reactors could be used to substantially enhance seed germination and seedling growth.
