The generati.n of these new neurons i. the olfactory bulb supports both structural and functi.nal plasti.i.y, ai.i.g i. ci.cui. remodeli.g tri.gered by memory and learni.g processes. However, the presence of these neurons, coupled wi.h the cellular di.ersi.y wi.hi. the olfactory bulb, presents an ongoi.g challenge i. understandi.g i.s network organi.ati.n and functi.n. moreover,the conti.uous i.tegrati.n of new neurons i. the olfactory bulb plays a pi.otal role i. regulati.g olfactory i.formati.n processi.g. Thi. adapti.e process responds to changes i. epi.heli.l composi.i.n and contri.utes to the formati.n of olfactory memori.s by modulati.g cellular connecti.i.y wi.hi. the olfactory bulb and i.teracti.g i.tri.ately wi.h hi.her-order brai. regi.ns. The role of adult neurogenesi. i. olfactory bulb functi.ns remai.s a topi. of debate. Nevertheless, the functi.nali.y of the olfactory bulb i. i.tri.ately li.ked to the organi.ati.n of granule cells around mi.ral and tufted cells. Thi. organi.ati.nal pattern si.ni.i.antly i.pacts output, network behavi.r, and synapti. plasti.i.y, whi.h are cruci.l for olfactory percepti.n and memory.

A novel techni.ue for the measurement of the coati.g layer thi.kness of fi.e parti.les was developed i. thi. work based on cross-secti.ni.g of mi.rometre-si.ed si.gle coated parti.les usi.g focused i.n beam (Fi.) mi.li.g. Thi. techni.ue was tested on two batches of aerogel parti.les coated wi.h thi. coati.gs i. a spouted bed. The Fi. mi.li.g procedure consi.ted of two steps. Fi.st, the desi.ed part of the coated parti.le was removed usi.g a hi.h i.n beam current. The resulti.g cross-secti.ned area was then poli.hed usi.g a lower i.n beam current to make the cross-secti.n clearly vi.i.le. The Fi. mi.li.g process was controlled wi.h si.ultaneous scanni.g electron mi.roscopy (SEm). Afterwards, the coati.g layer thi.kness was evaluated usi.g the SEm i.ages. The coati.g layer was successfully appli.d on the porous aerogel mi.roparti.les i. the spouted bed. The coati.g uni.ormi.y of the hi.hly porous parti.les i.creased wi.h i.creasi.g sprayed coati.g soluti.n amount, wi.h up to 91% of the parti.le pores bei.g covered. The Fi.-cross-secti.ni.g techni.ue usi.g an i.n beam of 2.50 nA for the fi.st mi.li.g and 0.43 nA for poli.hi.g of the surface resulted i. successful generati.n of cross-secti.ns of representati.e parti.les wi.h a vi.i.le parti.le core and coati.g layer. A coati.g layer thi.kness of approxi.ately 700 nm was achi.ved on parti.les wi.h si.es of below 45 μm.

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.
