a.oma.ous ion hea. tra.sport is a.a.yzed in the T-10 toka.a. pla.ma.hea.ed with electron cyclotron resona.ce hea.ing(ECRH) in second-ha.monic extra.ordina.y mode. Predictive modeling with empirica. sca.ing for Ohmica. hea. conductivity shows tha. in ECRH pla.ma. the ca.cula.ed ion tempera.ure could be overestima.ed, so a. increa.e of a.oma.ous ion hea. tra.sport is required. To study this effect two sca.s a.e presented: over the EC resona.ce position a.d over the ECRH power. The EC resona.ce position va.ies from the high-field side to the low-field side by va.ia.ion of the toroida. ma.netic field. The sca. over the hea.ing power is presented with on-a.is a.d mixed ECRH regimes. discha.ges with high a.oma.ous ion hea. tra.sport a.e obta.ned in a.l considered regimes. In these discha.ges the power ba.a.ce ion hea. conductivity exceeds the neocla.sica. level by up to 10 times. The high ion hea. tra.sport regimes a.e distinguished by three pa.a.eters: the ra.io Te/Ti, the norma.ized electron density gra.ient R/■, a.d the ion–ion collisiona.ity νii~*. The combina.ion of high Te/Ti, high νii~*, a.d R/■=6-10 results in va.ues of norma.ized a.oma.ous ion hea. fluxes up to 10 times higher tha. in the low tra.sport scena.io.

The electrochemica. CO_(2) reduction rea.tion(CO_(2)RR) to controlla.le chemica.s is considered a. a.promising pa.hwa. to store intermittent renewa.le energy. Herein, a.set of ca.a.ysts ba.ed on copper-nitrogendoped ca.bon xerogel(Cu-N-C) a.e successfully developed va.ying the copper a.ount a.d the na.ure of the copper precursor, for the efficient CO_(2)RR. The electroca.a.ytic performa.ce of Cu-N-C ma.eria.s is a.sessed by a.rota.ing ring-disc electrode(RRdE), technique still ra.ely explored for CO_(2)RR. for compa.ison, products a.e a.so cha.a.terized by online ga. chroma.ogra.hy in a.H-cell. The a.-synthesized Cu-NC ca.a.ysts a.e found to be a.tive a.d highly CO selective a. low overpotentia.s(from -0.6 to -0.8 v ***) in 0.1 m KHCO_(3), while H_(2) from the competitive wa.er reduction a.pea.s a. la.ger overpotentia.s(-0.9 v vs. RHE). The optimum copper a.eta.e-derived ca.a.yst conta.ning Cu-N_(4) moieties exhibits a.CO_(2)-to-CO turnover frequency of 997 h^(-1) a. -0.9 v vs. RHE with a.H_(2)/CO ra.io of 1.8.
