cross section of the d 3he α p reaction of relevance for fusion Plasma Applications
Nuclear Fusion, 2010Co-Authors: G Gorini, J KallneAbstract:The cross section of the d + 3He → α + p fusion reaction has been determined with regard to its systematic variation with energy (ECM) based on the available experimental data. Information is provided on the angular distribution dσ/dΩ(θp, E) at energies up to ECM = 8.0 MeV and the total cross section σ(ECM) for the range ECM = 3.0–8.0 MeV. The relevance of the presented results for fusion Plasmas heated with RF heating of 3He minority in D and DT Plasmas is discussed.

Nanoscience with non-equilibrium Plasmas at atmospheric pressure
Journal of Physics D: Applied Physics, 2011Co-Authors: T Belmonte, G Arnoult, G Henrion, T GriesAbstract:number: 81.16.-c Methods of nanofabrication and processing 52.77.-j Plasma Applications Abstract This review devoted to nanoscience with atmospheric pressure Plasmas shows how nanomaterials are synthesised locally using three main ways: localized PECVD, nanoparticles and templates. On the other hand, self-organization of nano-objects on surfaces is driven by electric fields, stress and high temperatures. We show that the specificities of Plasmas at high pressure, as their small size, their self-organization or their filamentation have been little exploited in the synthesis of nanomaterials. Finally, perspectives in the field are given. 3

Absolute atomic oxygen and nitrogen densities in radio-frequency driven atmospheric pressure cold Plasmas: Synchrotron vacuum ultra-violet high-resolution Fourier-transform absorption measurements
Applied Physics Letters, 2013Co-Authors: K. Niemi, Jeanpaul Booth, D. O'connell, N. De Oliveira, D. Joyeux, L. Nahon, T. GansAbstract:Reactive atomic species play a key role in emerging cold atmospheric pressure Plasma Applications, in particular, in Plasma medicine. Absolute densities of atomic oxygen and atomic nitrogen were measured in a radio-frequency driven non-equilibrium Plasma operated at atmospheric pressure using vacuum ultra-violet (VUV) absorption spectroscopy. The experiment was conducted on the DESIRS synchrotron beamline using a unique VUV Fourier-transform spectrometer. Measurements were carried out in Plasmas operated in helium with air-like N2/O2 (4:1) admixtures. A maximum in the O-atom concentration of (9.1 ± 0.7)×1020 m−3 was found at admixtures of 0.35 vol. %, while the N-atom concentration exhibits a maximum of (5.7 ± 0.4)×1019 m−3 at 0.1 vol. %.

Cold Plasma in Medicine and Healthcare: The New Frontier in Low Temperature Plasma Applications
Frontiers in Physics, 2020Co-Authors: Mounir LaroussiAbstract:Low temperature Plasmas that can be generated at atmospheric pressure and at temperatures below 40 oC have in the past couple of decades opened up a new frontier in Plasma Applications: biomedical Applications. These Plasma sources produce agents, such as reactive species (radicals and non-radicals), charged particles, photons, and electric fields, which have impactful biological effects. Investigators have been busy elucidating the physical and biochemical mechanisms whereby low temperature Plasma affects biological cells on macroscopic and microscopic scales. A thorough understanding of these mechanisms is bound to lead to the development of novel Plasma-based medical therapies. This mini review introduces the reader to this exciting multidisciplinary field of research.

reactive species in non equilibrium atmospheric pressure Plasmas generation transport and biological effects
Physics Reports, 2016Co-Authors: G V Naidis, David B. Graves, Mounir Laroussi, Stephan Reuter, Ken OstrikovAbstract:Non-equilibrium atmospheric-pressure Plasmas have recently become a topical area of research owing to their diverse Applications in health care and medicine, environmental remediation and pollution control, materials processing, electrochemistry, nanotechnology and other fields. This review focuses on the reactive electrons and ionic, atomic, molecular, and radical species that are produced in these Plasmas and then transported from the point of generation to the point of interaction with the material, medium, living cells or tissues being processed. The most important mechanisms of generation and transport of the key species in the Plasmas of atmospheric-pressure Plasma jets and other non-equilibrium atmospheric-pressure Plasmas are introduced and examined from the viewpoint of their Applications in Plasma hygiene and medicine and other relevant fields. Sophisticated high-precision, time-resolved Plasma diagnostics approaches and techniques are presented and their Applications to monitor the reactive species and Plasma dynamics in the Plasma jets and other discharges, both in the gas phase and during the Plasma interaction with liquid media, are critically reviewed. The large amount of experimental data is supported by the theoretical models of reactive species generation and transport in the Plasmas, surrounding gaseous environments, and Plasma interaction with liquid media. These models are presented and their limitations are discussed. Special attention is paid to biological effects of the Plasma-generated reactive oxygen and nitrogen (and some other) species in basic biological processes such as cell metabolism, proliferation, survival, etc. as well as Plasma Applications in bacterial inactivation, wound healing, cancer treatment and some others. Challenges and opportunities for theoretical and experimental research are discussed and the authors’ vision for the emerging convergence trends across several disciplines and application domains is presented to stimulate critical discussions and collaborations in the future.
