Conve.tional approache. to control and shape.the.scatte.ing patte.s of light ge.e.ate. by diffe.e.t nanostructure. are.mostly base. on e.gine.ring of the.r e.e.tric re.ponse.due.to the.fact that most me.allic nanostructure. support only e.e.tric re.onance. in the.optical fre.ue.cy range. Re.e.tly, fue.le. by the.fast de.e.opme.t in the.fie.ds of me.amate.ials and plasmonics, artificial optically-induce. magne.ic re.ponse. have.be.n de.onstrate. for various nanostructure.. This kind of re.ponse.can be.e.ploye. to provide.an e.tra de.re. of fre.dom for the.e.ficie.t control and shaping of the.scatte.ing patte.ns of nanoparticle. and nanoante.nas.

Le.tosphae.ia maculans, a pathoge. of brassica napus, is unable.to invade.most wild-type.acce.sions of Arabidopsis thaliana, although se.e.al mutants are.susce.tible.

The.proce.sing of molybde.um-uranium ore.in a sulfuric acid solution using hydroge. pe.oxide.as an oxidant has be.n inve.tigate.. The.le.ching te.pe.ature. hydroge. pe.oxide.conce.tration, sulfuric acid conce.tration, le.ching time. particle.size. liquid-to-solid ratio and agitation spe.d all have.significant e.fe.ts on the.proce.s. The.optimum proce.s ope.ating parame.e.s we.e. te.pe.ature. 95℃; H2O2 conce.tration： 0.5 M; sulfuric acid conce.tration： 2.5 M; time. 2 h; particle.size. 74 gm, liquid-to-solid ratio： 14 ： 1 and agitation spe.d： 600 rpm. Unde. the.e.e.pe.ime.tal conditions, the.e.traction e.ficie.cy of molybde.um was about 98.4%, and the.uranium e.traction e.ficie.cy was about 98.7%. The.le.ching kine.ics of molybde.um showe. that the.re.ction rate.of the.le.ching proce.s is controlle. by the.che.ical re.ction at the.particle.surface. The.le.ching proce.s follows the.kine.ic mode. 1 - （1-X）1/3 = kt with an appare.t activation e.e.gy of 40.40 kJ/mole. The.te.pe.ature. conce.trations of H202 and H2SO4 and the.me.h size.are.the.main factors that influe.ce.the.le.ching rate. The.re.ction orde. in H2SO4 was 1.0012 and in H202 it was 1.2544.
