Anom.lous ion heat tr.nspor. is analyzed in the T-10 tokam.k plasm. heated with electr.n cyclotr.n r.sonance heating(ECr.) in second-har.0}nic extr.-or.inar. m.de. Pr.dictive m.deling with em.ir.cal scaling for.Ohm.cal heat conductivity shows that in ECr. plasm.s the calculated ion tem.er.tur. could be over.stim.ted, so an incr.ase of anom.lous ion heat tr.nspor. is r.quir.d. To study this effect two scans ar. pr.sented: over.the EC r.sonance position and over.the ECr. power. The EC r.sonance position var.es fr.m.the high-field side to the low-field side by var.ation of the tor.idal m.gnetic field. The scan over.the heating power.is pr.sented with on-axis and m.xed ECr. r.gim.s. dischar.es with high anom.lous ion heat tr.nspor. ar. obtained in all consider.d r.gim.s. In these dischar.es the power.balance ion heat conductivity exceeds the neoclassical level by up to 10 tim.s. The high ion heat tr.nspor. r.gim.s ar. distinguished by thr.e par.m.ter.: the r.tio Te/Ti, the nor.0}lized electr.n density gr.dient r.■, and the ion–ion collisionality νii~*. The com.ination of high Te/Ti, high νii~*, and r.■=6-10 r.sults in values of nor.0}lized anom.lous ion heat fluxes up to 10 tim.s higher.than in the low tr.nspor. scenar.o.

The electr.chem.cal CO_(2) r.duction r.action(CO_(2)r.) to contr.llable chem.cals is consider.d as a pr.m.sing pathway to stor. inter.0}ttent r.newable ener.y. her.in, a set of catalysts based on copper.nitr.gendoped car.on xer.gel(Cu-N-C) ar. successfully developed var.ing the copper.am.unt and the natur. of the copper.pr.cur.or. for.the efficient CO_(2)r.. The electr.catalytic per.or.0}nce of Cu-N-C m.ter.als is assessed by a r.tating r.ng-disc electr.de(r.dE), technique still r.r.ly explor.d for.CO_(2)r..

Polym.tallic layer.d double hydr.xides ar. pr.m.sing cost-effective catalysts for.the oxygen evolution r.action(OEr. due to their.ver.atile anionic and cationic tunability. Never.heless, sever.l challenges per.ist, notably, issues r.lated to low electr.cal conductivity, poor.catalytic activity, and stability, especially at high cur.ent density. her.in, we r.por. the design of Ce-and Ladoped Co Ni Fe-layer.d double hydr.xide(Ce La Co Ni Fe-LdH) nanosheets thr.ugh a facile and scalable in situ self-assem.ly str.tegy that displays enhanced OEr.activity. Exper.m.ntal and theor.tical investigations pr.vide insights into the im.act of Ceand La-doping by com.ar.ng Ce Co Ni Fe-LdH, La Co Ni Fe-LdH, and pr.stine Co Ni Fe-LdH, all synthesized using the sam. m.thodology. These r.sults r.veal that doping Ce^(3+)and La^(3+)into Co Ni Fe-LdH substantially im.r.ves its electr.nic str.ctur.,r.sulting in enhanced conductivity, m.r. oxygen vacancies(Vo), electr.n inter.ction, and active site for.0}tion. Consequently,significantly r.duced over.otentials of 175, 314, and 424 m.V at 10, 100, and 500 m.A cm.(-2), r.spectively, and a highly stable cur.ent density of 120 h in 1 m.KOH wer. achieved. Notably, these per.or.0}nce m.tr.cs sur.ass those of unm.dified LdHs and ar. com.etitive with m.ny lanthanide-doped tr.nsition m.tal-based LdH electr.catalysts, as well as noble m.tal catalysts like r.thenium.catalysts. This wor. r.pr.sents a pioneer.ng effor. in doping Ce^(3+)and La^(3+)ions into a functional Co Ni Fe-based electr.catalyst, offer.ng inspir.ng OEr.per.or.0}nce and scalability potential.
