Available in PDF, EPUB and Kindle. Book excerpt: Gas plasma is the fourth state of matter, alongside solid, liquid, and gas. There are many naturally-occurring events and man-made products related to gas plasma, including aurora, thunderstorms, high-intensity discharge headlamp bulbs, oxonizers, semiconductors, and solar battery panels. A gas plasma is generated by removing electrons from a gas, e.g. nitrogen gas, to produce a highly-excited mixture of charged nuclei and free electrons. It has enormous potential as a broad spectrum antimicrobial sterilization procedure with applications in medical, industrial, and agricultural settings (e.g. decontamination of medical instruments). A major advantage is the shallow penetration of gas plasmas: approximately 10-20 nanometers from the surface, thereby minimizing damage to the material being sterilized. An important obstacle to overcome is the 'understanding-gap' between the engineering researchers who are developing the gas plasma sterilization technology and the microbiologists who aim to fine tune it for their needs. This timely book bridges that gap, permitting engineers and microbiologists to develop more coherent multidisciplinary strategies. The book opens with introductory chapters that explain the background and principles of gas plasma sterilization and outline the possible mechanisms of action. The requirements for achieving the 'gold-standard' sterilization level, i.e. a sterility assurance level (SAL) of 10-6, are also covered. The book also covers the applications of this technology, ranging from the inactivation of spores and endotoxins to inactivation of viruses and seed-borne plant pathogens. The final section of the book tackles sterilization validation (from several ISO documents), common data-interpretation errors, and speculation about future trends.

This book was released on 2012-02-03 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-thermal (cold) plasmas at atmospheric pressure have recently found many breakthrough applications in biology, medicine, and food security. Plasmas can efficiently kill bacteria, yeasts, moulds, spores, biofilms and other hazardous microorganisms, including potential bio-terrorism agents. They can be employed for bio-decontamination and sterilization of surfaces, medical instruments, water, air, food, even of living tissues without causing their damage. Direct or indirect plasma interaction with living cells of microorganisms or even humans enables novel bio-medical applications, e.g. treatment of skin diseases and ulcers. Plasma-enhanced blood coagulation coupled with its antiseptic properties proved success in wound healing and opens new possibilities in surgery, emergency medicine and military applications. Plasma treatment allows cell manipulations, their removal and targeted transfer into the injured area, which can accelerate wound healing. Plasma induced apoptosis (programmed cell death) of tumor cells brings forth a great potential for cancer treatment. Besides, plasma enables painless treatment of dental caries, root canal disinfection, and other dentistry applications. This book is a selection of reviewed manuscripts issuing from the NATO Advanced Research Workshop Plasma for bio-decontamination, medicine and food security held in Jasná, Slovakia, on 15-18 March 2011. It provides a comprehensive overview of the current knowledge and research activities focused at the plasma applications in areas such as bio-decontamination, water chemistry, effects on cells; biofilm inactivation, UV sterilization, and medicine, especially tissue treatment and wound healing, as well as dentistry and food security.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Steady-state atmospheric pressure nonthermal plasmas can splendidly debilitate bacteria in liquids, gases and on surfaces, as well as can disintegrate hazardous chemicals. The nonthermal gas discharge at atmospheric pressure, such as resistive barrier discharge is investigated for low temperature sterilization purposes. In specific, exploring and understanding the hidden secrets of the plasma sterilization mechanisms and the intensification of the main microbial reduction pathways are the objectives of the research. A dual-mode steady-state atmospheric pressure resistive barrier ionized gas (plasma) generator has been designed and developed to meet the environmental health and federally mandated safety standards. Electrical, chemical, optical, and biological studies are carried out on the Steady-State, Atmospheric Pressure Resistive Barrier Discharge, with the intent of identifying the chemically and biologically active species produced. The goals of the research work are to prepare an effective, inexpensive plasma sterilization process and to identify and escalate the main contributing active species responsible for plasma sterilization. The effectiveness of ionized gases produced by the resistive barrier plasma discharge on sterilizing bacteria has been analyzed. Bacteria at a dilution that achieved a countable number of colonies were exposed or not exposed to ionized gases for various periods of time and monitored to determine the effects of ionized gas treatment.

Book excerpt: This unified introduction provides the tools and techniques needed to analyze plasmas and connects plasma phenomena to other fields of study. Combining mathematical rigor with qualitative explanations, and linking theory to practice with example problems, this is a perfect textbook for senior undergraduate and graduate students taking one-semester introductory plasma physics courses. For the first time, material is presented in the context of unifying principles, illustrated using organizational charts, and structured in a successive progression from single particle motion, to kinetic theory and average values, through to collective phenomena of waves in plasma. This provides students with a stronger understanding of the topics covered, their interconnections, and when different types of plasma models are applicable. Furthermore, mathematical derivations are rigorous, yet concise, so physical understanding is not lost in lengthy mathematical treatments. Worked examples illustrate practical applications of theory and students can test their new knowledge with 90 end-of-chapter problems.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the worldwide population increases, maintaining a standard of public health becomes more critical. Two major concerns in this area are nosocomial infections (NI) and water contamination. Current processes in sterilization and water treatment have limitations that could be overcome using plasma techniques. The unique characteristics of plasma make it a promising alternative for energy-intensive processes. This work investigated the characteristics of plasma that have the greatest impact on sterilization and the reactivation of activated carbon. Previous studies have researched the physical and chemical surface properties of biochar but have not been able to establish an efficient process to activate biochar with desired characteristics. Plasma treatment would offer a way to etch the surface of biochar and specifically functionalize the surface. Successfully activating biochar would increase its adsorption ability and enable its use for water treatment. This project aims to harness these plasma properties and use plasmas to address three important topics related to public health: sterilization of surfaces, modulating commercial activated carbon (AC), and activations of biochar.Cold plasma sterilization offers an efficient way to sterilize medical components and instruments without the risk of deformation to heat-sensitive materials. This paper reports the use of magnetized plasma to realize low-temperature sterilization. A radio frequency dielectric barrier discharge was created in a quartz tube using a mixture of argon and oxygen gas. Glass slides inoculated with a uniform amount of Escherichia coli were exposed to the plasma afterglow at different pressures with and without a magnetic field. A global model was developed to evaluate the magnetically enhanced dielectric barrier discharges and predict species densities. Optical emission spectroscopy identified the plasma species present and validated the model. The magnetic field significantly promoted the intensity of the plasma and the sterilization efficiency. A process gas pressure of 100 mTorr presented the most effective treatment with a sterilization time less than one minute and sample temperature below 32 ℗ʻC.The effects of O2 plasma on the adsorption capacity of activated carbon (AC) was investigated by varying treatment times. Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and Zeta potential were used to characterize the surface properties of the AC. The carbon was then applied to remove methylene blue (MB) from an aqueous solution. The adsorption kinetics and isotherm were also studied. Results showed that pseudo-second-order kinetics was the most suitable model for describing the adsorption of MB onto AC. Equilibrium data were well fitted to the Freundlich and Langmuir isotherm models. The highest adsorption capacity resulted from 4 minutes of O2 plasma treatment. This work shows that activation of AC by plasma can open the micropore and increase the effectiveness of chemical removal.Biochar was activated using a combination of O2 plasma and KOH. The adsorption capacity was investigated for different O2 plasma treatment times, KOH concentrations, and treatment temperatures. The adsorption capacity of methylene blue (MB) by the plasma activated biochar was evaluated. The adsorption kinetics and isotherm were also investigated. Results showed that pseudo-second-order kinetics was the most suitable model for describing the adsorption of MB onto biochar. Both the Freundlich and Langmuir isotherm models fit the equilibrium data. The highest adsorption capacity resulted from 10\\% KOH + 300 ℗ʻC for 5 minutes. This work shows that activation of biochar by plasma can improve adsorption capacity.The plasma treated AC and the plasma activated biochar were applied to the removal of PFOA. It was demonstrated that plasma treatment can improve PFOA adsorption. The negative surface charge was shown to negatively impact PFOA adsorption which aligns with the hypothesis that PFOA would preferentially adsorb onto more positive surfaces due to its anionic state in water.
