“…The maximum levels of NO and NO2 recommended by the National Institute for Occupational Safety and Health for 8 hours of sustained breathing are 25 ppm and 5 ppm, accordingly. At the working range of 20 mm for the MicroPlaSter systems, the NO2 values are less than 1 ppm (155). NO values under 25 ppm for the MiniFlatPlaSter were reported for therapy periods up to a few minutes.…”

Cold atmospheric plasma (CAP) is a novel technology with boundless significance that can be used in the medical sector that offers noninvasive in-vivo applications without damaging the living tissues. CAPs can be obtained by curtailing the concentration of high-energetic electrons per phase and by freezing molecules/atoms (devoid of charge) in plasma utilizing gas circulation and atmospheric air, which includes a variety of charged and neutral reactive entities, UV rays, electric currents, and fields, etc. that have an influence on cellular material in a multitude of diverse manners. Reactive oxygen species (ROS) and reactive nitrogen species (RNS), produced by the plasma, essentially cause biological and therapeutically advantageous plasma effects. CAP plasma has several important biological functions, including the deactivation of pathogens, induction of tissue restoration and cell propagation, the annihilation of cells by triggering apoptosis, etc. Several fundamental concepts are defined, even if the precise process of the effect of plasma on biomolecules is still not properly identified. Depending on the biological synthesis of RNS and ROS in reactions to plasma emissions, the present review described several aspects of plasma therapy in neuroscience, particularly in anti-glioblastoma, neuro-differentiation, and neuroprotection and also the various applications of CAP in medical fields where it is used in the therapy of SARS-CoV-2, cancer therapy, and chronic and acute wounds. Furthermore, the proliferation in stem cells, dental medicines, dermatology, and a brief insight into CAP devices and their risk factors was highlighted.

Nuclear energy accounts for ≈10% of global energy production, positioning it as a promising solution for achieving carbon neutrality amid escalating concerns over climate change. Nonetheless, the effective management of radioactive waste, which can remain hazardous for up to one hundred thousand years, presents considerable challenges that must be addressed to uphold public trust and safeguard environmental safety. This review outlines the fundamental stages of nuclear decommissioning including strategic planning, decontamination, dismantling, remediation, encapsulation, deregulation, and site reuse as a critical component of sustainable environmental practices. The review also highlights the significance of efficient decontamination processes in reducing waste generation. Various decontamination techniques, including mechanical, electromechanical, chemical, and advanced methods such as laser and plasma decontamination, are evaluated for their effectiveness and limitations. Moreover, the review emphasizes the need to enhance the recovery and recycling of ion exchange resin and potential radionuclides during decontamination processes to minimize waste and to address the depletion of potential radionuclide resources. Future research should prioritize the development of innovative techniques for decontamination and radioactive waste management, fostering sustainable decommissioning and supporting the ongoing development of nuclear energy in an environmentally responsible manner.
