Grant-in-Aid for Transformative Research Areas (A) has been started from April, 2024

Project area name is "Plasma-driven seed memory operation: Frontiers in molecular dynamics in seeds driven by plasma"

24H02254 "プラズマ駆動生化学反応の学理構築：活性種の動態解析" (KAKEN) Principal investigator: Kenji Ishikawa

Plasma-based in situ functionalization based on functional nitrogen science

Functional nitrogen science is now emerged for effective utilization of reactive nitrogen species (RNS). The technologies are related to water and air plasma-based nitrogen fixation. Electron impact reactions and chemical reactions among nitrogen, oxygen, and hydrogen, can occur on non-equilibrium plasma processing. Key issues are on in situ generation of RNS at the point of use and plasma-based nitrogen cycles of ammonia and nitric acid. (link to) Ishikawa Jpn. J. Appl. Phys. 61 SA0802 (2022).

HIGHLIGHTS (II)

↑

Metabolomic profiles display a novel mechanism on cell death that is induced specifically by incubation in the non-thermal plasma treated solutions

The plasma-activated lactated solution (PAL) exhibits antitumor effects in glioblastoma U251SP cells. The PAL-treated U251SP cells exhibited changes in intracellular metabolites that were reductive in the redox state.

Synergistic Formation of Radicals by Irradiation with both Vacuum Ultraviolet and Atomic Hydrogen: a Real-time in situ Electron Spin Resonance Study

We report on the surface modification of polytetrafluoroethylene (PTFE) as an example of soft- and bio-materials that occur under plasma discharge by kinetics analysis of radical formation using in situ real-time electron spin resonance (ESR) measurements. During irradiation with hydrogen plasma, simultaneous measurements of the gas-phase ESR signals of atomic hydrogen and the carbon dangling bond (C-DB) on PTFE were performed. Dynamic changes of the C-DB density were observed in real time, where the rate of density change was accelerated during initial irradiation and then became constant over time. It is noteworthy that C-DBs were formed synergistically by irradiation with both vacuum ultraviolet (VUV) and atomic hydrogen. The in situ real-time ESR technique is useful to elucidate synergistic roles during plasma surface modification.
