Obtaining high yields in agricultural production is essential due to the world's population growth and increased food demand. At same time, adverse effects of agriculture on environment need be kept a minimum. Low temperature plasmas (LTPs) show promise as efficient green technologies for enhancing productivity while maintaining good quality safety many steps cycle. As result, applications LTPs have led creation new, rapidly developing field called “plasma agriculture.” Here, we briefly...
Abstract Plasma medicine refers to the application of nonequilibrium plasmas at approximately body temperature, for therapeutic purposes. Nonequilibrium are weakly ionized gases which contain charged and neutral species electric fields, emit radiation, particularly in visible ultraviolet range.
