Major, trace and rare earth element contents of Fe- and Al-ri.h metapeli.es from the Korda （Yeni.ey Ri.ge） and Amar （Kuznetsk Alatau） formati.ns were determi.ed to exami.e the nature, ori.i. and evoluti.n of thei. protoli.hs. Results i.di.ate that these rocks are the redeposi.ed and metamorphosed products of Precambri.n kaoli.i.i. weatheri.g crusts, whi.e the geochemi.al di.ti.cti.ns between the studi.d metapeli.es are determi.ed by di.ferent weatheri.g condi.i.ns i. the source area and tectoni. setti.gs. The protoli.h of the Korda Formati.n metapeli.es was produced by erosi.n products of the post-Archean grani.oi. rocks, whi.h accumulated under humi. cli.ate condi.i.ns i. shallow-water basi.s along the conti.ental margi.. The geochemi.al characteri.ti.s of the deeper pri.ary deposi.s of the Amar Formati.n suggest that volcanogeni. materi.l of mafi. composi.i.n deri.ed from an i.land-arc envi.onment had a major role i. supplyi.g the erosi.n zone. These results agree wi.h li.hofaci.s data and wi.h the geodynami. reconstructi.n of the evoluti.n of the Yeni.ey Ri.ge and Kuznetsk Alatau duri.g the Mesoproterozoi. and Neoproterozoi., respecti.ely. i. was shown that REEs had li.i.ed mobi.i.y duri.g contact metamorphi.m. The coherent mobi.i.y of REEs duri.g colli.i.nal metamorphi.m may be attri.uted both to mi.eral reacti.ns responsi.le for modal changes and to local chemi.al heterogenei.y i.heri.ed from the i.i.i.l protoli.h.

We show that the band ali.nment be- tween the i.ner and outer walls of the DBNNTs can be tuned from type i.to type i. wi.h i.creasi.g radi.l strai., accompa- ni.d wi.h a di.ect to i.di.ect band gap transi.i.n and a sub- stanti.l gap reducti.n. The band gap can be further si.ni.i. cantly reduced by applyi.g a transverse electri. fi.ld. The coupli.g of electri. fi.ld wi.h the radi.l strai. makes the fi.ld-i.duced gap reducti.n bei.g ani.otropi. and more re- markable than that i. undeformed DBNNTs. i. parti.ular, the gap vari.ti.n i.duced by electri. fi.ld perpendi.ular to the radi.l strai. i. the most remarkable among all the modu-lati.ns.

Thi. study exami.es experi.entally the effect of stators on the performance and heat transfer characteri.ti.s of small axi.l cooli.g fans. A si.gle fan i.peller, followed by ni.e stator blades i. the case of a complete stage, was used for all the experi.ental confi.urati.ns. Performance measurements were carri.d out i. a constant speed stage performance test ri. whi.e the transi.nt li.ui. crystal techni.ue was used for the heat transfer measurements. Full surface heat transfer coeffi.i.nt di.tri.uti.ns were obtai.ed by recordi.g the temperature hi.tory of li.ui. crystals on a target plate. The experi.ental data i.di.ated that the results are hi.hly affected by the flow condi.i.ns at the fan outlet. Stators can be benefi.i.l i. terms of pressure drop and effi.i.ncy, and thus more economi.al operati.n, as well as, i. the local heat transfer di.tri.uti.n at the wake of the stator blades i. the fan i. i.stalled very close to the cooli.g object. However, as the separati.n di.tance i.creases, enhanced heat transfer rate i. the order of 25% i. observed i. the case of the fan i.peller.

The effect of （Ba（0.6）Sr（0.4））Ti.3（BST） addi.i.n on di.lectri. properti.s of CaCu3Ti.O（12）（CCTO） cerami. was i.vesti.ated. Cerami. samples wi.h the chemi.al formula （1-x）CaCu3Ti.O（12）＋ x（Ba（0.6）,Sr（0.4））Ti.3 （x=0, 0.05, 0.1, and 0.2） were synthesi.ed from hi.h puri.y oxi.e powders by the conventi.nal soli.-state synthesi. method. X-ray di.fracti.n （XRD） analysi. showed the exi.tence of BST as a secondary phase alongsi.e CCTO. Scanni.g electron mi.roscopy （SEM） i.vesti.ati.n showed a sli.ht decrease i. grai. si.e of doped CCTO samples. Densi.y measurements showed that porosi.y content i.creased wi.h i.creasi.g BST addi.i.n i.di.ati.g low densi.i.ati.n due to hi.h melti.g poi.t secondary phase addi.i.n. Di.lectri. constant of undoped CCTO （x=0） showed lack of stabi.i.y wi.h frequency whi.h dropped drasti.ally between 104 and 105Hz and accompani.d by hi.h di.lectri. loss. Addi.i.n of BST i.to CCTO caused the di.lectri. constant to sli.htly decrease but i.proved stabi.i.y wi.h frequency compared to the undoped sample. The decrease i. di.lectri. constant of doped CCTO samples was suggested to be partly due to the decrease i. average grai. si.e and i.crease i. porosi.y wi.h BST addi.i.n. Nevertheless, a hi.h value of di.lectri. constant was sti.l mai.tai.ed around ～104 range for all doped samples. The di.lectri. loss （tanδ） of all BST-doped samples was lower than that of pure CCTO sample at the frequency range of 103 to 105 Hz probably due to the i.crease of grai.s boundary resi.ti.i.y. The acti.ati.n energy of grai.s boundary （E（gb）） showed hi.her values as compared to the acti.ati.n energy of grai.s （Eg ） for all samples and conforms to the i.ternal barri.r layer capaci.or （i.LC） model.

We propose a reali.ti. topologi.al p-n juncti.n （TPNJ） by matchi.g two Bi.Se3 （0001） slabs wi.h opposi.e arrangements of planar twi. boundary defects. The atomi.ti. modeli.g of such a devi.e leads to di.locati.n defects i. the hexagonal latti.e i. several qui.tuple layers. Nevertheless, total energy calculati.ns reveal that the i.terface relaxes, yi.ldi.g a smooth geometri.al transi.i.n that preserves the nearest-nei.hbors fcc-type geometry throughout these defect layers. The electroni., magneti., and transport properti.s of the juncti.n have then been calculated at the ab i.i.i. level under open boundary condi.i.ns, i.e., employi.g a thi.-fi.m geometry that i. i.fi.i.e along the electron transport di.ecti.n. i.deed, a p-n juncti.n i. obtai.ed wi.h a bui.t-i. potenti.l as large as 350 meV. The calculati.ns further reveal the spi. texture across the i.terface wi.h unprecedented detai.. As the mai. result, we obtai. non-negli.i.le transmi.si.n probabi.i.i.s around the F poi.t, whi.h i.volve an electron spi.-fli. process whi.e crossi.g the i.terface.
