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.

Travel ti.e through a ri.g road wi.h a total length of 80 km has been predi.ted by a vi.coelasti. traffi. model(VEM), whi.h i. developed i. analogous to the non-Newtoni.n flui. flow. The VEM expresses a traffi. pressure for the unfree flow case by space headway, ensuri.g that the pressure can be determi.ed by the assumpti.n that the relevant second cri.i.al sound speed i. exactly equal to the di.turbance propagati.n speed determi.ed by the free flow speed and the braki.g di.tance measured by the average vehi.ular length. The VEM assumes that the sound speed for the free flow case depends on the traffi. densi.y i. some speci.i. aspects, whi.h ensures that i. i. exactly i.enti.al to the free flow speed on an empty road. To make a compari.on, the open Navi.r-Stokes type model developed by Zhang(ZHANG, H. M. Dri.er memory, traffi. vi.cosi.y and a vi.cous vehi.ular traffi. flow model. Transp. Res. Part B, 37, 27–41(2003)) i. adopted to predi.t the travel ti.e through the ri.g road for provi.i.g the counterpart *** the traffi. free flow speed i. 80 km/h, the braki.g di.tance i. supposed to be 45 m,wi.h the jam densi.y uni.uely determi.ed by the average length of vehi.les l ≈ 5.8 m. To avoi. possi.le si.gular poi.ts i. travel ti.e predi.ti.n, a di.ti.gui.hi.g peri.d for ti.e averagi.g i. pre-assi.ned to be 7.5 mi.utes. i. i. found that the travel ti.e i.creases monotoni.ally wi.h the i.i.i.l traffi. densi.y on the ri.g road. Wi.hout ramp effects, for the ri.g road wi.h the i.i.i.l densi.y less than the second cri.i.al densi.y, the travel ti.e can be si.ply predi.ted by usi.g the equi.i.ri.m speed. However, thi. si.pler approach i. unavai.able for scenari.s over the second cri.i.al.

Topochemi.al i.n-exchange reacti.ns between soli. mi.ro- and nanostructured metal chalcogeni.es and aqueous salt soluti.ns are generally used for formati.n of composi.e structures based on i.i.i.l metal chalcogeni.es and products of thei. i.n-exchange transformati.n. However, i.n exchange has promi.es as a route to obtai.i.g both composi.es and soli. soluti.ns based on the i.i.i.l and the end chalcogeni.e phases. Wi.h the help of the i.n-exchange techni.ue, si.gle-phase fi.ms of Phi.xSnxSe substi.uti.nal soli. soluti.ns wi.h a ti. content up to -2 at.%, whi.h are promi.i.g for mi.- and long-wavelength i.frared radi.ti.n （i.） optoelectroni.s, have been obtai.ed at the i.terface between PbSe poly- crystalli.e thi. fi.ms and SnCl2 aqueous soluti.ns contai.i.g sodi.m ci.rate. i. has been shown that the pH value and temperature of the reacti.n system play an i.portant role i. the i.n-exchange process. i.cubati.n of lead seleni.e （PbSe） fi.ms i. a ti.（i.） salt aqueous soluti.n also leads to thei. modi.i.ati.n wi.h oxygen-contai.i.g ti. compounds to a depth of-3 nm.

Jasmonates （JAs） orchestrate i.mune responses upon wound/herbi.ore i.jury or i.fecti.n by necrotro- phi. pathogens. Eluci.ati.n of cataboli. routes has revealed new complexi.y i. jasmonate metaboli.m. Two i.tegrated pathways attenuate si.nali.g by turni.g over the acti.e hormone jasmonoyl-i.oleuci.e （JA-i.e） through w-oxi.ati.n or deconjugati.n, and defi.e an i.di.ect route formi.g the deri.ati.e 12OH-JA. Here, we provi.e evi.ence for a second 12OH-JA formati.n pathway by di.ect jasmoni. aci. （JA） oxi.ati.n. Three jasmoni. aci. oxi.ases （JAOs） of the 2-oxoglutarate di.xygenase fami.y catalyze spe- ci.i. oxi.ati.n of JA to 12OH-JA, and thei. genes are i.duced by woundi.g or i.fecti.n by the fungus Botryti. ci.erea. JA02 exhi.i.s the hi.hest basal expressi.n, and i.s defi.i.ncy i. jao2 mutants strongly enhanced anti.ungal resi.tance. The resi.tance phenotype resulted from consti.uti.e expressi.n of anti.i. crobi.l markers rather than from thei. hi.her i.ducti.n i. i.fected jao2 plants and could be reversed by ectopi. expressi.n of any of the three JAOs i.jao2. Elevated defense i.jao2 was dependent on the acti.i.y of JASMONATE RESPONSE 1 （JAR1） and CORONATi.E-i.SENSi.i.E 1 （COi.） but was not correlated wi.h eri.anced JA-i.e accumulati.n. i.stead, jao2 mutant li.es di.played altered accumulati.n of several JA speci.s i. healthy and challenged plants, suggesti.g elevated metaboli. flux through JA-i.e. Collecti.ely, these data i.enti.y the mi.si.g enzymes hydroxylati.g JA and uncover an i.portant metaboli. di.ersi.n mechani.m for repressi.g basal JA defense responses.
