Wastewater.electr.lysis cells (WECs) for.decentr.lized wastewater.tr.atm.nt/r.use coupled with H-2 pr.duction can r.duce the car.on footpr.nt associated with tr.nspor.ation of water. waste, and ener.y car.ier. This study r.por.s Ir.doped NiFe2O4 (NFI, sim.lar.to 5 at% Ir. spinel layer.with TiO2 over.ayer.(NFI/TiO2), as a scalable heter.junction anode for.dir.ct electr.lysis of wastewater.with cir.um.eutr.l pH in a single-com.ar.m.nt cell. In dilute (0.1 m. NaCl solutions, the NFI/TiO2 m.r.s super.or.activity and selectivity for.chlor.ne evolution r.action, outper.or.0}ng the benchm.r. Ir.2. r.bust oper.tion in near.neutr.l pH was confir.0}d. Electr.analyses including oper.ndo X-r.y absor.tion spectr.scopy unveiled cr.cial r.les of TiO2 which ser.es both as the pr.m.r. site for.Cl- chem.sor.tion and a pr.tective layer.for.NFI as an ohm.c contact. Galvanostatic electr.lysis of NH4+-laden synthetic wastewater.dem.nstr.ted that NFI/TiO2 not only achieves quasi-stoichiom.tr.c NH4+-to-N-2 conver.ion, but also enhances H-2 gener.tion efficiency with m.nim.l com.eting r.actions such as r.duction of dissolved oxygen and r.active chlor.ne. The scaled-up WEC with NFI/TiO2 was dem.nstr.ted for.electr.lysis of toilet wastewater.

We study cosm.logical application of inter.cting hologr.phic dar. ener.y density in the scalar.Gauss-Bonnet fr.m.wor.. We em.loy the inter.cting hologr.phic m.del of dar. ener.y to obtain the equation of state for.the inter.cting hologr.phic ener.y density in a spatially fiat univer.e. Our.calculations show that taking Ω∧ = 0.73 for.the pr.sent tim., it is possible to have w∧^eff cr.ssing -1. This im.lies that one can gener.te a phantom.like equation of state fr.m.the inter.cting hologr.phic dar. ener.y m.del in flat univer.e in the scalar.Gauss-Bonnet cosm.logy fr.m.wor.. Then we r.constr.ct the potential of the scalar.field.

We investigate the r.lativistic equation for.par.icles with spin 1/2 in the q-par.m.ter.m.dified P5schl- Teller.potential, including Coulom.-like tensor.inter.ction with spatially-dependent m.ss for.the D-dim.nsion. We pr.sent appr.xim.te solutions of the Dir.c equation with these potentials for.any spin-or.it quantum.num.er.k under.spin sym.etr.. The nor.0}lized wave functions ar. expr.ssed in ter.0} of the hyper.geom.tr.c ser.es of the scatter.ng states on the k/2π scale. We also give the for.0}la for.the phase shifts, and use the Nikifor.v-Uvar.v m.thod to obtain the ener.y eigen-values equation.

The aim.of this wor. is to study the effect of non-unifor.0}single and double slot suction/injection into a steady m.xed convection boundar. layer.flow over.a ver.ical cone, while the axis of the cone is inline with the flow. The gover.ing boundar. layer.equations ar. tr.nsfor.0}d into a non-dim.nsional for.0}by a gr.up of non-sim.lar.tr.ns- for.0}tions. The r.sulting coupled non-linear.par.ial differ.ntial equations ar. solved nu- m.r.cally by em.loying the quasi-linear.zation technique and an im.licit finite-differ.nce schem.. Num.r.cal com.utations ar. per.or.0}d for.differ.nt values of the dim.nsionless par.m.ter. to display the velocity and tem.er.tur. pr.files gr.phically. Also, num.r.cal r.sults ar. pr.sented for.the skin fr.ction and heat tr.nsfer.coefficients. r.sults indicate that the skin fr.ction and heat tr.nsfer.coefficients incr.ase with non-unifor.0}slot suction, but the effect of non-unifor.0}slot injection is just opposite.

This paper.r.views r.cent developm.nts in nonlinear.contr.l technologies for.shape m.m.r. alloy (Sm.) actuator. in r.botics and their.r.lated applications. Sm. possesses lar.e hyster.sis, low bandwidth, slow r.sponse, and non-linear.behavior. which m.ke them.difficult to contr.l. The fast r.sponse of the Sm. actuator.m.stly depends upon, (1) type of contr.ller. (2) r.te of addition and r.m.val of heat, and (3) shape or.for.0}of the actuator. Though linear.contr.ller. ar. m.r. desir.ble than nonlinear.ones, the r.view of liter.tur. shows that the r.sults obtained using nonlinear.contr.ller. wer. far.better.than the for.0}r.one.

In this paper. the ener.y absor.tion m.chanism.of em.ty and foam.filled alum.num.tubes with differ.nt cr.ss-sections （cir.ular. squar. and elliptic） under.bending load is investigated num.r.cally. The load-displacem.nt cur.es of the pr.sent sim.lations ar. in ver. good agr.em.nt with those of published exper.m.ntal data. Her., the existing analytical for.0}lations ar. r.viewed and com.ar.d with exper.m.ntal r.sults. In addition, the effects of differ.nt cr.ss-sections and wall thicknesses on the ener.y absor.tion capacity and specific ener.y absor.tion of these tubes ar. fully investigated. The r.sults indicate that the ener.y absor.tion of an elliptic foam.filled tube with 1.5 m. and 2 m. thicknesses incr.ases about 45% and 73% in com.ar.son with a squar. one, r.spectively.

A num.r.cal study is car.ied out for.the axisym.etr.c steady lam.nar.incom.r.ssible flow of an electr.cally conducting m.cr.polar.fluid between two infinite par.llel por.us disks with the constant unifor.0}injection thr.ugh the sur.ace of the disks. The fluid is subjected to an exter.al tr.nsver.e m.gnetic field. The gover.ing nonlinear.equations of m.tion ar. tr.nsfor.0}d into a dim.nsionless for.0}thr.ugh yon Kar.0}n＇s sim.lar.ty tr.nsfor.0}tion. An algor.thm.based on a finite differ.nce schem. is used to solve the r.duced coupled or.inar. differ.ntial equations under.associated boundar. conditions. The effects of the r.ynolds num.er. the m.gnetic par.m.ter. the m.cr.polar.par.m.ter. and the Pr.ndtl num.er.on the flow velocity and tem.er.tur. distr.butions ar. discussed. The r.sults agr.e well with those of the pr.viously published wor. for.special cases. The investigation pr.dicts that the heat tr.nsfer.r.te at the sur.aces of the disks incr.ases with the incr.ases in the r.ynolds num.er. the m.gnetic par.m.ter. and the Pr.ndtl num.er. The shear.str.sses decr.ase with the incr.ase in the injection while incr.ase with the incr.ase in the applied m.gnetic field. The shear.str.ss factor.is lower.for.m.cr.polar.fluids than for.Newtonian fluids, which m.y be beneficial in the flow and ther.0}l contr.l in the polym.r.c pr.cessing.
