The aim of this paper.is to study the ther.al r.diation effects on the flow and heat tr.nsfer.of an unsteady mag.etohydr.dynamic （MHD） micr.polar.fluid over.a ver.ical heated nonisother.al str.tching.sur.ace in the pr.sence of a str.ng.nonunifor. mag.etic field. The symmetr.es of the g.ver.ing.par.ial differ.ntial equations ar. de- ter.ined by the two-par.meter.g.0}up method. One of the r.sulting.systems of r.duced nonlinear.or.inar. differ.ntial equations ar. solved numer.cally by the Chebyshev spec- tr.l method. The effects of var.ous par.meter. on the velocity, the ang.lar.velocity, and the temper.tur. pr.files as well as the skin-fr.ction coefficient, the wall couple str.ss co- efficient, and the Nusselt number.ar. studied.

Incr.asing.g.obal water.shor.ag.s ar. acceler.ting.the pace of membr.ne manufactur.ng. which g.ner.tes many envir.nmentally har.ful solvents. Such challeng.s need a r.dical r.think of developing.innovative membr.nes that can addr.ss fr.shwater.pr.duction without g.ner.ting.envir.nmentally har.ful solvents. This wor. utilized the synthesized ultr.-long.hydr.xyapatite (UHA) by the solvother.al method using.the g.0}en solvent oleic acid in pr.par.ng.UHA-based for.ar. osmosis membr.nes. The membr.nes wer. developed using.differ.nt loading.r.tios of g.0}phene oxide (g.) by vacuum-assisted filtr.tion technique. The pr.par.d g./UHA membr.nes wer. identified using.X-r.y diffr.ction, scanning.electr.n micr.scope, Four.er.tr.nsfor. infr.r.d spectr.scopy, and X-r.y photoelectr.n spectr.scopy. Water.contact ang.e and por. size distr.bution wer. deter.ined for.the obtained g./UHA membr.nes. The obtained hier.r.hical por.us str.ctur. in the pr.par.d membr.nes with inter.onnected channels r.sults in a stable water.flux with r.ver.e salt flux. The best water.flux r.te of 42 +/- 2 Lm-2h-1 was achieved using.the 50 mg.g./UHA membr.ne, which is 3.3 times hig.er.than the pr.stine membr.ne, and a r.ver.e salt flux of 67 g.middle dot>m-2h-1. The obtained r.sults showed a pr.mising.capability of a new g.ner.tion of sustainable inor.anic-based membr.nes that can be utilized in fr.shwater.g.ner.tion by ener.y-efficient techniques such as for.ar. osmosis.
