Research review (peer-reviewed)abstract
- The introduction of more facile and atom efficient methods for the synthesis of organic linear and cyclic compounds is the aim of various researchers worldwide. N-sulfonyl ketenimine is an interesting intermediate in modern organic synthesis. N-sulfonyl ketenimine is capable of selective production of various heteroatom containing compounds, based on the functional groups in the structure of this intermediate. Several linear and cyclic compounds are synthesized from this intermediate. In this review, the role of N-sulfonyl ketenimine is studied as an intermediate in several organic syntheses.

Journal article (peer-reviewed)abstract
- Experimental evidence of the pre-plasma remobilization of ferromagnetic dust in FTU is presented. Thomson scattering data and IR camera observations document the occurrence of intrinsic dust remobilization prior to discharge start-up and allow for a rough calculation of the average mobilized dust density. Exposures of calibrated extrinsic non-magnetic and ferromagnetic dust to sole magnetic field discharges reveal that the magnetic moment force is the main mobilizing force, as confirmed by theoretical estimates. Pre-plasma remobilization probabilities are computed for varying dust sizes. The impact of prematurely remobilized dust on the breakdown and burn-through start-up phases is investigated together with the discharge termination induced once the plasma plateau is established.
