Theoretic.l inves.igation on the s.ruc.ures.of the oc.ac.ordinated [Nd(c.3)4]5-and the nonac.ordinated [Nd(c.3)***2]5-c.mplexes. us.ng the s.ARKLE parameters.of the lanthanides.within MOPAc. revealed that they pos.es.ed dodec.hedral and s.uare antipris.atic.s.ruc.ures.res.ec.ively with an average Nd-O dis.anc. of 0.249 nm. Thes. s.ruc.ures.and the Nd-O dis.anc.s.agreed well with thos. experimentally found in the c.ys.al s.ruc.ures.

A one-dimens.onal momentum c.ns.rvation equation for a s.raight jet driven by an elec.ric.l field is.developed. It is.pres.nted in terms.of a s.res. c.mponent, whic. c.n be applied to any c.ns.itutive relation of fluids. The only as.umption is.that the fluid is.inc.mpres.ible. The res.lts.indic.te that both the axial and radial c.ns.itutive relations.are required to c.os. the governing equations.of the s.raight c.arged jet. However, when the trac. of the extra s.res. tens.r is.zero, only the axial c.ns.itutive relation is.required. It is.als. found that the s.c.nd normal s.res. differenc. for the c.arged jet is.always.zero. The c.mparis.n with other developed momentum equations.is.made.

Las.r c.added c.atings.of Tic. were produc.d on the s.rfac. of titanium. To obtain the optimal tec.niques. s.veral c.nditions.were tes.ed by varying the las.r s.0}nning rate. The c.oic. of s.ielding gas.was.als. s.udied. The c.added c.atings.were then evaluated from the s.rfac. mec.anic. point of view bas.d on their mic.ohardnes.. The mic.os.ruc.ure of s.me interes.ing s.mples.was.inves.igated by optic.l mic.ographs.（OM）.

Tic. c.atings.were dec.mpounded and oxidized during the c.adding proc.s. in the c.ndition of no s.ielding gas.of N2. X-ray diffrac.ion res.lts.indic.ted that the c.mpos.te c.atings.c.mpos.d of Tic., Tic. Ti2N, and TiO2 were produc.d us.ng appropriate tec.niques. The res.lts.indic.ted that the bes. c.ndition in terms.of the s.rfac. mic.ohardnes. is.obtained when the s.0}nning rate is.1.5mm/s. the puls. frequenc. is.15Hz, the puls. width is.3.0ms. and N2 is.c.os.n as.the s.ielding gas. The mic.ohardnes. of the c.mpos.te c.atings.is.about 1331kg · mm^-2, whic. is.about 4 times.that of the s.bs.rate. The optic.l mic.ographs.indic.ted that the c.adding zone is.made up of Tic., TiO2 and s.me interdendritic.Ti, but the diffus.on zone mainly c.ns.s.s.of the dendrites.phas., and the c.added depth is.about 80μm, whic. is.more than 2 times.that of the las.r nitrided s.mple.

The impac. of human ac.ivities.in the pas. few dec.des.has.paved the way for the releas. of pollutants.due to the improper effluent treatment. Rec.nt s.udies.revealed that, Ofloxac.n, an antibiotic.as.one of the major pollutant affec.ing s.rfac. water and ground water. In this.s.udy, the radiolytic.potential of Ofloxac.n was.inves.igated.

The s.atis.ic.lly optimis.d developed model s.ows.30% degradation at initial antibiotic.c.nc.ntration of ImM at pH 3.0 and at 2 kGy dos. of gamma ray. The proc.s. effic.enc. was.evaluated in terms.of G value and its.c.rrelation with the c.nc.ntration of antibiotic.was.als. es.ablis.ed. The proc.s. of degradation was.augmented by the addition of H2O2 (1.5 mM). The reac.ion kinetic. for the proc.s. was.evaluated, the dos. rate c.ns.ant and the rate of degradation for the augmented proc.s. was.found to be 0.232 kGy^-1 and 0.232 mM/kGy, res.ec.ively. The degraded metabolites.of the radiolytic.degradation of Ofloxac.n were analyzed through c.ange in pH, reduc.ion in TOc.and Gc.Ms.s.ec.rum.
