假如生活欺骗了你

疯狂英语（新读写） 2024年第5期 1-1页

作者： aleksandr Sergeyevich Pushkin 不详

假如生活欺骗了你,不要悲伤,不要心急!忧郁的日子里须要镇静:相信吧,快乐的日子将会来临。心儿永远向往着未来;现在却常是忧郁:一切都是瞬息,一切都将会过去;而那过去了的,就会成为亲切的怀恋。

Pha.e tra.sitions a.d ma.netic properties of sha.e-memory ma.eria.s ca. be ta.lored by tuning the size of the constituent ma.eria.s, such a. na.opa.ticles. However, owing to the la.k of suita.le synthetic methods for size-controlled Heusler na.opa.ticles, there is no report on the size dependence of their properties a.d functiona.ities. In this contribution, we present the first chemica. synthesis of size-selected Co-Ni-Ga.Heusler na.opa.ticles. We a.so report the structure a.d ma.netic properties of the bipha.ic Co-Ni-Ga.na.opa.ticles with sizes in the ra.ge of 30-84 nm, prepa.ed by a.SBa.15 na.oporous silica. templa.ed a.proa.h. The pa.ticle sizes could be rea.ily tuned by controlling the loa.ing a.d concentra.ion of the precursors. The fra.tions a.d crysta.lite sizes of ea.h pha.e of the Co-Ni-Ga.na.opa.ticles a.e closely rela.ed to their pa.ticle size. Enha.ced ma.netiza.ion a.d decrea.ed coercivity a.e observed with increa.ing pa.ticle size. The Curie tempera.ure （To） of the Co-Ni-Ga.na.opa.ticles a.so depends on their size. The 84 nm-sized pa.ticles exhibit the highest Tc （≈ 1,174 K） a.ong a.l known Heusler compounds. The very high Curie tempera.ures of the Co-Ni-Ga.na.opa.ticles render them promising ca.dida.es for a.plica.ion in high-tempera.ure sha.e memory a.loy-ba.ed devices.

Ensembles of freeze-dried self-rolled polymer micro-scrolls a.e explored a. templa.e media.for produc- ing ca.bon-iron ba.ed composites with fibrous morphology.

The resulting ma.eria. ha. a.micro-fibrous mor- phology a.d is ba.ica.ly composed of meta.lic Fe^0 a.d FeO pa.ticles, i.e., more tha. 98 wt% of the ca.bon/ iron-ba.ed composite ma.s.

This pa.er reports on a.molecula. dyna.ics study of structura. rea.ra.gements in a.copper na.ocrysta. during nuclea.ion of pla.tic deforma.ion under unia.ia. tension. The study shows tha. the resulting nuclea.ion of pa.tia. disloca.ions on the free surfa.e a.d their glide occurs through loca. fcc→bcc→hcp tra.sforma.ions via.consistent a.omic displa.ements. We propose a. a.omic model for the genera.ion of disloca.ions a.d twins ba.ed on loca. reversible fcc→bcc→fcc tra.sforma.ions, with the reverse one proceeding through a. a.terna.ive system.
