Yet, a grand challenge is to unify both features in one material. We show that a plain medium-manganese steel can be processed to have a tensile strength >2.2 gigapascals at a uniform elongation >20%. This requires a combination of multiple transversal forging, cryogenic treatment, and tempering steps. A hierarchical microstructure that consists of laminated and twofold topologically aligned martensite with finely dispersed retained austenite simultaneously activates multiple micromechanisms to strengthen and ductilize the material. The dislocation slip in the well-organized martensite and the gradual deformation-stimulated phase transformation synergistically produce the high ductility. Our nanostructure design strategy produces 2 gigapascal–strength and yet ductile steels that have attractive composition and the potential to be produced at large industrial scales.Unveiling facet-dependent degradation and facet engineering for stable perovskite solar cells稳(Wen)定(Ding)钙(Gai)钛(Zuo)矿(Kuang)太(Tai)阳(Yang)能(Neng)电(Dian)池(Chi)的(De)面(Mian)依(Yi)赖(Lai)性(Xing)降(Jiang)解(Jie)和(He)面(Mian)工(Gong)程(Cheng)▲ 作(Zuo)者(Zhe)：CHUNQING MA, FELIX T.

Here, we reveal the underlying mechanisms of facet-dependent degradation of formamidinium lead iodide (FAPbI3) films. We show that the (100) facet is substantially more vulnerable to moisture-induced degradation than the (111) facet. With combined experimental and theoretical studies, the degradation mechanisms are revealed; a strong water adhesion following an elongated lead-iodine (Pb-I) bond distance is observed, which leads to a δ-phase transition on the (100) facet. Through engineering, a higher surface fraction of the (111) facet can be achieved, and the (111)-dominated crystalline FAPbI3 films show exceptional stability against moisture. Our findings elucidate unknown facet-dependent degradation mechanisms and kinetics.微(Wei)生(Sheng)物(Wu)学(Xue)MicrobiologyDome1–JAK–STAT signaling between parasite and host integrates vector immunity and development寄(Ji)生(Sheng)虫(Chong)和(He)宿(Su)主(Zhu)间(Jian)信(Xin)号(Hao)传(Chuan)递(Di)整(Zheng)合(He)媒(Mei)介(Jie)免(Mian)疫(Yi)和(He)发(Fa)育(Yu)▲ 作(Zuo)者(Zhe)：VIPIN S.

Unlike most geographically confined tick species that prefer a single vertebrate host, Ixodes spp. can parasitize many vertebrates and transmit diverse pathogens. Ixodid ticks undergo only three feeding events during their multiyear lifespan, ingesting blood meals that are nearly 100 times their weight. Their characteristic physiological adaptations were likely shaped by their sophisticated hematophagy and associations with coevolving vertebrate hosts. The molecular basis of how ticks maintain their complex postembryonic developmental program as well as their vectorial competence remains unclear. Ticks contain a functional JAK–STAT signaling cascade that induces robust antibacterial responses capable of limiting the proliferation of tick-borne pathogens. The pathway is activated in many arthropods by cytokine-like molecules such as Unpaired (UPD). However, the Ixodes scapularis genome is unusually devoid of recognizable UPD orthologs.ApoE isoform– and microbiota-dependent progression of neurodegeneration in a mouse model of tauopathyTau小(Xiao)鼠(Shu)病(Bing)理(Li)模(Mo)型(Xing)解(Jie)析(Xi)依(Yi)赖(Lai)ApoE亚(Ya)型(Xing)和(He)微(Wei)生(Sheng)物(Wu)群(Qun)的(De)神(Shen)经(Jing)退(Tui)行(Xing)性(Xing)疾(Ji)病(Bing)▲ 作(Zuo)者(Zhe)：DONG-OH SEO, DAVID O’DONNELL, NIMANSHA JAIN, JASON D.

In this study, neuromorphic functions were successfully accomplished with a polyelectrolyte-confined fluidic memristor (PFM), in which confined polyelectrolyte–ion interactions contributed to hysteretic ion transport, resulting in ion memory effects. Various electric pulse patterns were emulated by PFM with ultralow energy consumption. The fluidic property of PFM enabled the mimicking of chemical-regulated electric pulses. More importantly, chemical-electric signal transduction was implemented with a single PFM. With its structural similarity to ion channels, PFM is versatile and easily interfaces with biological systems, paving a way to building neuromorphic devices with advanced functions by introducing rich chemical designs.Long-term memory and synapse-like dynamics in two-dimensional nanofluidic channels二(Er)维(Wei)纳(Na)米(Mi)流(Liu)体(Ti)通(Tong)道(Dao)中(Zhong)的(De)长(Chang)时(Shi)记(Ji)忆(Yi)和(He)突(Tu)触(Chu)样(Yang)动(Dong)力(Li)学(Xue)▲ 作(Zuo)者(Zhe)：P.

Recent advances have enabled the confinement of water and ions to two dimensions, unveiling transport properties inaccessible at larger scales and triggering hopes of reproducing the ionic machinery of biological systems. Here we report experiments demonstrating the emergence of memory in the transport of aqueous electrolytes across (sub)nanoscale channels. We unveil two types of nanofluidic memristors depending on channel material and confinement, with memory ranging from minutes to hours. We explain how large time scales could emerge from interfacial processes such as ionic self-assembly or surface adsorption. Such behavior allowed us to implement Hebbian learning with nanofluidic systems. This result lays the foundation for biomimetic computations on aqueous electrolytic chips.
写头条这五个多月来，我收入最多的一篇文章四月份写的，当时，我很少写文章，估计是头条君为了鼓励我多写文章而给我的惊喜。老司机辣评：我觉得宝马的电动车型几乎被消费者遗忘了，虽然宝马i3、iX3等车型的降价幅度甚至达到了10万元，但对于销量的提升微乎其微，不难看出宝马已经焦虑了。而国产的宝马iX1缺乏亮点，外观造型没太大区别，内饰设计不出彩，续航表现也一般，并且作为双电机版本，宝马iX1对电耗的控制也并不出色，百公里耗电量16.3千瓦·时，确实是高电耗，因此其在续航方面表现不佳。【图】吉明步础痴番号种子全集迅雷下载,作品在线观看冲1冲八...混血冰山美人,出道11年引退,只为过平凡生活—希崎杰西卡触...
