In the present study, the deta.led rea.tion mecha.isms were developed a.d Chemkin 4.1.1 wa. implemented to predict the forma.ion of polluta.t species in compressed na.ura. ga. （CNG） fired interna. combustion （IC） engine. The proposed mecha.isms were developed by coupling the EXGa. （a. a.toma.ic mecha.ism genera.ion tool for a.ka.e oxida.ion） mecha.isms with the Leed＇s NOz mecha.ism （version 2.0）. The simula.ion results of ea.h proposed mecha.ism were va.ida.ed by the experimenta. mea.urements for profiles of tempera.ure, pressure a.d polluta.t species （CO, NOx）. The ra.e of production a.a.ysis of ea.h mecha.ism identified the importa.t rea.tions in ea.h mecha.ism which contributed to the forma.ion of polluta.t species. In spite of some discrepa.cies, the experimenta. mea.urements indica.e tha. Mecha.ism-IV （consisting of 208 rea.tions a.d 78 species） showed closer a.reement for ea.h of the predicted profiles of tempera.ure, pressure a.d polluta.t species （CO, NOx）.

The processes reported for the prepa.a.ion of la.tha.um hexa.oride (La.6) from la.tha.um oxide involve the use of ca.bon either elementa. or in the form of boron ca.bide or elementa. boron itself a. reducing a.ents, fused sa.ts a. high tempera.ures or rea.tions which require the product boride to be lea.hed out. Ea.h of these techniques either increa.es the process costs a.d/or increa.es cha.ces of conta.ina.ion in fi-na. product. Pure La.6 ca. best be prepa.ed by a.rea.tion which produces a.ga.eous byproduct. In the present study, such a.rea.tion wa. successfully used to yield pure la.tha.um hexa.oride. The process involved mixing of a.hydrous la.tha.um chloride with a.uminium a.d boron a.d hea.ing the cha.ges under dyna.ic a.gon flow. La.tha.um chloride is known to be highly hygroscopic; hence the process using improperly dehydra.ed La.l3 led to the forma.ion of la.tha.um oxychloride which does not convert to La.6 under conditions wherein La.l3 converts. Not only the forma.ion of a.Cl3 but a.so its continuous remova. from the rea.tion zone is necessa.y for the success of the process.

a.thorough understa.ding of how proteins induce na.opa.ticle （NP） a.grega.ion is crucia. when designing in vitro a.d in vivo a.sa.s a.d interpreting experimenta. results. This knowledge is a.so crucia. when developing na.o-a.plica.ions a.d formula.ion for drug delivery systems. In this study, we found tha. extra.tion of immunoglobulin G （IgG） from cow serum results in lower polystyrene NPs a.grega.ion. Moreover, a.dition of isola.ed IgG or fibrinogen to feta. cow serum enha.ced this a.grega.ion, thus demonstra.ing tha. these fa.tors a.e ma.or drivers of NP a.grega.ion in serum. Counter-intuitively, NP a.grega.ion wa. inversely dependent on protein concentra.ion; i.e., low protein concentra.ions induced la.ge a.grega.es, wherea. high protein concentra.ions induced sma.l a.grega.es. Protein-induced NP a.grega.ion a.d a.grega.e size were monitored by a.sorba.ce a. 400 nm a.d dyna.ic light sca.tering, respectively. Here, we propose a.mecha.ism behind the protein concentra.ion dependent a.grega.ion; this mecha.ism involves the effects of multiple protein intera.tions on the NP surfa.e, surfa.e a.ea.limita.ions, a.grega.ion kinetics, a.d the influence of other serum proteins.
