The sudden a.pea.a.ce of diverse a.giosperms in the fossil record wa. referred to by Da.win a. the “a.omina.le mystery,”hence contributing to the heightened interest in a.giosperm evolution. a.giosperms displa. wide ra.ges of morphologica., physiologica.,a.d ecologica. cha.a.ters, some of which ha.e proba.ly influenced their species richness.

Following the grea. successes of phylogenetic a.a.yses using pla.tid sequences,dozens to thousa.ds of nuclea. genes from next-genera.ion sequencing ha.e been used in a.giosperm phylogenomic a.a.yses, providing well resolved phylogenies a.d new insights into the evolution of a.giosperms. in this review we focus on recent nuclea. phylogenomic a.a.yses of la.ge a.giosperm cla.es, orders, fa.ilies,a.d subdivisions of some fa.ilies a.d provide a.summarized Nuclea.

Heterogeneous ca.a.ysis pla.s a.crucia. role in the chemica. industry, which ha. evolved from the investiga.ion of chemisorption to a. electronic structure[1]. Diverse stra.egies, such a. a.loying,doping, a.d confining, ha.e been a.plied to enha.ce the ca.a.ytic properties of a.tive sites through electronic modula.ion. The electron tra.sfer between a.tive sites a.d substra.es profoundly influences ca.a.ytic a.tivity [2].
