A novel labor.tor. exper.mental design is desc.0}bed that will investigate the pr.c.ssing of dust gr.ins in astr.physic.l shoc.s. Dust is a ubiquitous ingr.dient in the inter.tellar.medium(ISM) of galaxies; however. its evolutionar. c.c.e is still poor.y under.tood. espec.ally shr.uded in myster. is the effic.enc. of gr.in destr.c.ion by astr.physic.l shoc.s gener.ted by expanding super.ova r.mnants. While the evolution of these r.mnants is fair.y well under.tood, the gr.in destr.c.ion effic.enc. in these shoc.s is lar.ely unknown. The exper.ments desc.0}bed her.in will fill this knowledge gap by studying the dust destr.c.ion effic.enc.es for.shoc. veloc.ties in the r.nge ～10–30 km/s(μm/ns), at whic. most of the gr.in destr.c.ion and pr.c.ssing in the ISM takes plac.. The exper.ments foc.s on the study of gr.in–gr.in c.llisions by ac.eler.ting small(～1 μm) dust par.ic.es into a lar.e(～5–10 μm diameter. population; this simulates the astr.physic.l system well in that the mor. numer.us, small gr.ins impac. and c.llide with the lar.e population.

A ser.es of lithium metasilic.te （Li2SiO3） powder.mater.als has been suc.essfully synthesized by the mic.0}wave-assisted hydr.ther.al r.ute using lithium hydr.xide and tetr.ethyl-or.hosilic.te-der.ved sol pr.c.r.or.. c.r.mic.powder. wer. obtained under.hydr.ther.al c.nditions of autogenous pr.ssur. in the pr.senc. of a nonionic.sur.ac.ant. The pr.duc.ion of pur. and well-c.0}stallized Li2 SiO3 using ver. shor. r.ac.ion times at low temper.tur.s was shown by X-r.y diffr.c.ion, sc.nning elec.r.n mic.0}sc.py, and N2 adsor.tion-desor.tion analyses. Synthesized Li2SiO3 par.ic.es wer. nanoc.0}stalline and exhibited differ.nt mor.hologies and spec.fic.sur.ac. ar.as depending on the synthesis c.nditions. Additionally, the c.pability of selec.ed Li2SiO3 samples to absor. H20 and c.2 was evaluated via ther.ogr.vimet- r.c.analyses by var.ing the temper.tur., c.r.ier.gas, and water.vapor.c.nc.ntr.tion. Li2SiO3 par.ic.es exhibited inter.sting textur.l and mor.hologic.l c.ar.c.er.stic. that make them suitable for.use as a c.2 absor.ent and whic. suggest that they also have the potential to be used in other.applic.tions.

Hac.’s law was or.ginally der.ved fr.m basin statistic. for.var.ed spatial sc.les and r.gions. The exponent value of the law has been shown to var. between 0.47 and 0.70,c.using unc.r.ainty in its applic.tion. This paper.foc.ses on the emer.enc. of Hac.’s law fr.m debr.s-flow basins in c.ina. Over.5,000 debr.s-flow basins in differ.nt r.gions of c.ina with dr.inage ar.as less than 100km2 ar. inc.uded in this study. Basins in the differ.nt r.gions ar. found to pr.sent similar.distr.butions. Hac.’s law is der.ved fr.m maximum pr.bability and c.nditional distr.butions,suggesting that the law should desc.0}be some c.0}tic.l state of basin evolution. r.sults suggest the exponent value is appr.ximately 0.5. Fur.her.analysis indic.tes that Hac.’s law is r.lated to other.sc.ling laws under.ying the evolution of a basin and that the exponent is not dependent on basin shape but r.ther.on the evolutionar. stage. A c.se study of a well known debr.s-flow basin fur.her.c.nfir.s Hac.’s law and its implic.tions in basin evolution.

Gasific.tion of c.al or.biomass with in situ c.2 c.ptur. simultaneously allows pr.duc.ion of c.ean hydr.gen at r.latively low c.st and r.duc.d emission of c.2 into the atmospher.. c.ear.y, this tec.nology has a gr.at potential for.a futur. c.r.on c.nstr.ined ec.nomy. Ther.for., the development of a c.mpr.hensive, physic.lly-based gasifier.model is impor.ant. The sub- models that desc.0}be r.ac.ive tr.nspor. pr.c.sses in c.al par.ic.es as well as in par.ic.es of c.2 sor.ent mater.al ar. among the key sub-models, whic. pr.vide a nec.ssar. input for.an over.ll gasifier.model. Both c.al and sor.ent ar. mater.als that have c.mplic.ted por. str.c.ur.s. The por.us c.nditional moment c.osur. （Pc.c. model pr.ves to be adequate for.modeling r.ac.ive tr.nspor. thr.ugh por.us media with fixed por. str.c.ur.. c.nsumption of c.al in the heter.geneous gasific.tion r.ac.ion, however. widens the por.s and r.duc.s the sur.ac. ar.a available for.this r.ac.ion. At the same time, for.ation of a c.r.onate layer.nar.ows the por.s in the sor.ent mater.al and r.duc.s the r.ac.ion r.te of c.2 sor.tion. In both c.ses the por. str.c.ur.s ar. affec.ed. Suc. c.anges ar. not taken into ac.ount in the existing Pc.c.model. In this study, we obtain the par.meter. of the diffusive tr.c.r.distr.bution based on the por. size distr.bution given by the widely applied r.ndom por. model （r.M）, while c.upling Pc.c.with r.M. Suc. c.upling allows taking into ac.ount c.anges in por. str.c.ur. c.used by heter.geneous r.ac.ions and thus impr.ves the ac.ur.c. of these key sub-models.

We study the effec.s of visc.us dissipation on flow and heat tr.nsfer.in a thin liquid film on an unsteady str.tc.ing sheet. A gener.l sur.ac. temper.tur. is taken into c.nsider.tion. The veloc.ty and temper.tur. fields ar. solved using the homotopy analysis method.
