We converted PbI2 into an inactive (PbI2)2RbCl compound by RbCl doping, which effectively stabilizes the perovskite phase. We obtained a certified PCE of 25.6% for FAPbI3 (FA, formamidinium) perovskite solar cells on the basis of this strategy. Devices retained 96% of their original PCE values after 1000 hours of shelf storage and 80% after 500 hours of thermal stability testing at 85°C.Ion-modulated radical doping of spiro-OMeTAD for more efficient and stable perovskite solar cellsspiro-OMeTAD离(Li)子(Zi)调(Diao)制(Zhi)自(Zi)由(You)基(Ji)掺(Chan)杂(Za)钙(Gai)钛(Zuo)矿(Kuang)电(Dian)池(Chi)▲ 作(Zuo)者(Zhe)：TIANKAI ZHANG, FENG WANG, HAK-BEOM KIM, IN-WOO CHOIN et al.▲ 链(Lian)接(Jie)：https://www.science.org/doi/10.1126/science.abo2757▲ 摘(Zhai)要(Yao)：我(Wo)们(Men)开(Kai)发(Fa)了(Liao)一(Yi)种(Zhong)新(Xin)的(De)spiro-OMeTAD掺(Chan)杂(Za)方(Fang)式(Shi)，通(Tong)过(Guo)使(Shi)用(Yong)稳(Wen)定(Ding)的(De)有(You)机(Ji)自(Zi)由(You)基(Ji)作(Zuo)为(Wei)掺(Chan)杂(Za)剂(Ji)，离(Li)子(Zi)盐(Yan)作(Zuo)为(Wei)掺(Chan)杂(Za)调(Diao)制(Zhi)剂(Ji)，避(Bi)免(Mian)了(Liao)氧(Yang)化(Hua)后(Hou)的(De)问(Wen)题(Ti)。我(Wo)们(Men)实(Shi)现(Xian)了(Liao)大(Da)于(Yu)25%的(De)能(Neng)量(Liang)转(Zhuan)换(Huan)效(Xiao)率(Lv)，并(Bing)大(Da)大(Da)提(Ti)高(Gao)了(Liao)恶(E)劣(Lie)条(Tiao)件(Jian)下(Xia)的(De)设(She)备(Bei)稳(Wen)定(Ding)性(Xing)。自(Zi)由(You)基(Ji)提(Ti)供(Gong)的(De)空(Kong)穴(Xue)极(Ji)化(Hua)子(Zi)可(Ke)以(Yi)瞬(Shun)间(Jian)增(Zeng)加(Jia)电(Dian)导(Dao)率(Lv)和(He)功(Gong)函(Han)数(Shu)（WF），而(Er)离(Li)子(Zi)盐(Yan)通(Tong)过(Guo)影(Ying)响(Xiang)空(Kong)穴(Xue)极(Ji)化(Hua)子(Zi)的(De)能(Neng)量(Liang)学(Xue)进(Jin)一(Yi)步(Bu)调(Diao)节(Jie)WF。这(Zhe)种(Zhong)有(You)机(Ji)半(Ban)导(Dao)体(Ti)掺(Chan)杂(Za)方(Fang)式(Shi)可(Ke)以(Yi)将(Jiang)导(Dao)电(Dian)性(Xing)和(He)功(Gong)函(Han)数(Shu)WF可(Ke)调(Diao)性(Xing)解(Jie)耦(Zuo)，可(Ke)以(Yi)激(Ji)发(Fa)其(Qi)他(Ta)光(Guang)电(Dian)器(Qi)件(Jian)的(De)进(Jin)一(Yi)步(Bu)优(You)化(Hua)。▲ Abstract：We developed a new doping strategy for spiro-OMeTAD that avoids post-oxidation by using stable organic radicals as the dopant and ionic salts as the doping modulator (referred to as ion-modulated radical doping). We achieved PCEs of >25% and much-improved device stability under harsh conditions. The radicals provide hole polarons that instantly increase the conductivity and work function (WF), and ionic salts further modulate the WF by affecting the energetics of the hole polarons. This organic semiconductor doping strategy, which decouples conductivity and WF tunability, could inspire further optimization in other optoelectronic devices.DNA-guided lattice remodeling of carbon nanotubesDNA引(Yin)导(Dao)的(De)碳(Tan)纳(Na)米(Mi)管(Guan)晶(Jing)格(Ge)重(Zhong)构(Gou)▲ 作(Zuo)者(Zhe)：ZHIWEI LIN, LETICIA C.

Through DNA screening we identify a sequence, C3GC7GC3, whose reaction with an (8,3) enantiomer yields minimum disorder-induced Raman mode intensities and photoluminescence Stokes shift, suggesting ordered defect array formation. Single-particle cryo–electron microscopy shows that the C3GC7GC3 functionalized (8,3) has an ordered helical structure with a 6.5 angstroms periodicity. Reaction mechanism analysis suggests that the helical periodicity arises from an array of G-modified carbon-carbon bonds separated by a fixed distance along an armchair helical line.

This operation regime enabled controlled shuttling and intercalation of protons in nanoseconds at room temperature in an energy-efficient manner. The devices showed symmetric, linear, and reversible modulation characteristics with many conductance states covering a 20× dynamic range. Thus, the space-time-energy performance of the all–solid-state artificial synapses can greatly exceed that of their biological counterparts.地(Di)球(Qiu)科(Ke)学(Xue)Earth ScienceConstraints on the adjustment of tidal marshes to accelerating sea level rise潮(Chao)汐(Xi)沼(Zhao)泽(Ze)调(Diao)节(Jie)对(Dui)在(Zai)海(Hai)平(Ping)面(Mian)加(Jia)速(Su)上(Shang)升(Sheng)的(De)制(Zhi)约(Yue)因(Yin)素(Su)▲ 作(Zuo)者(Zhe)：NEIL SAINTILAN, KATYA E.

Previous assessments of resilience to sea level rise, to which marshes can adjust by sediment accretion and elevation gain, revealed contrasting results, depending on contemporary or Holocene geological data. By analyzing globally distributed contemporary data, we found that marsh sediment accretion increases in parity with sea level rise, seemingly confirming previously claimed marsh resilience. However, subsidence of the substrate shows a nonlinear increase with accretion. As a result, marsh elevation gain is constrained in relation to sea level rise, and deficits emerge that are consistent with Holocene observations of tidal marsh vulnerability.生(Sheng)物(Wu)学(Xue)BiologyPollinators of the sea: A discovery of animal-mediated fertilization in seaweed海(Hai)洋(Yang)授(Shou)粉(Fen)者(Zhe)：海(Hai)藻(Zao)中(Zhong)动(Dong)物(Wu)介(Jie)导(Dao)受(Shou)精(Jing)的(De)发(Fa)现(Xian)▲ 作(Zuo)者(Zhe)：E.

This is particularly relevant in red algae, in which female gametes are not liberated and male gametes are not flagellated. Using experiments with the isopod Idotea balthica and the red alga Gracilaria gracilis, we demonstrate that biotic interactions dramatically increase the fertilization success of the alga through animal transport of spermatia on their body. This discovery suggests that animal-mediated fertilization could have evolved independently in terrestrial and marine environments and raises the possibility of its emergence in the sea before plants moved ashore.
