We demonstrate unexpected OOP ferroelectricity and piezoelectricity in untwisted, commensurate, and epitaxial MoS2/WS2 heterobilayers synthesized by scalable one-step chemical vapor deposition. We show d33 piezoelectric constants of 1.95 to 2.09 picometers per volt that are larger than the natural OOP piezoelectric constant of monolayer In2Se3 by a factor of ~6. We demonstrate the modulation of tunneling current by about three orders of magnitude in ferroelectric tunnel junction devices by changing the polarization state of MoS2/WS2 heterobilayers. Our results are consistent with density functional theory, which shows that both symmetry breaking and interlayer sliding give rise to the unexpected properties without the need for invoking twist angles or moiré domains.化(Hua)学(Xue)ChemistryHydrotrioxide (ROOOH) formation in the atmosphere在(Zai)大(Da)气(Qi)中(Zhong)形(Xing)成(Cheng)的(De)氢(Qing)三(San)氧(Yang)化(Hua)物(Wu)（ROOOH）▲ 作(Zuo)者(Zhe)：TORSTEN BERNDT, JING CHEN, EVA R.

Previously, it has been speculated that they are formed in the atmosphere through the gas-phase reaction of organic peroxy radicals (RO2) with hydroxyl radicals (OH). Here, we report direct observation of ROOOH formation from several atmospherically relevant RO2 radicals. Kinetic analysis confirmed rapid RO2 + OH reactions forming ROOOH, with rate coefficients close to the collision limit. For the OH-initiated degradation of isoprene, global modeling predicts molar hydrotrioxide formation yields of up to 1%, which represents an annual ROOOH formation of about 10 million metric tons. The atmospheric lifetime of ROOOH is estimated to be minutes to hours. Hydrotrioxides represent a previously omitted substance class in the atmosphere, the impact of which needs to be examined.Dynamic interplay between metal nanoparticles and oxide support under redox conditions氧(Yang)化(Hua)还(Huan)原(Yuan)条(Tiao)件(Jian)下(Xia)金(Jin)属(Shu)纳(Na)米(Mi)粒(Li)子(Zi)和(He)氧(Yang)化(Hua)物(Wu)载(Zai)体(Ti)之(Zhi)间(Jian)的(De)动(Dong)态(Tai)相(Xiang)互(Hu)作(Zuo)用(Yong)▲ 作(Zuo)者(Zhe)：H.

Transmission electron microscopy revealed that the strong metal-support interaction (SMSI)–induced encapsulation of platinum particles on titania observed under reducing conditions is lost once the system is exposed to a redox-reactive environment containing oxygen and hydrogen at a total pressure of ~1 bar. Destabilization of the metal–oxide interface and redox-mediated reconstructions of titania lead to particle dynamics and directed particle migration that depend on nanoparticle orientation. A static encapsulated SMSI state was reestablished when switching back to purely oxidizing conditions. This work highlights the difference between reactive and nonreactive states and demonstrates that manifestations of the metal-support interaction strongly depend on the chemical environment.地(Di)球(Qiu)科(Ke)学(Xue)Earth SciencePersistent influence of precession on northern ice sheet variability since the early Pleistocene早(Zao)更(Geng)新(Xin)世(Shi)以(Yi)来(Lai)岁(Sui)差(Cha)对(Dui)北(Bei)部(Bu)冰(Bing)盖(Gai)变(Bian)化(Hua)的(De)持(Chi)续(Xu)影(Ying)响(Xiang)▲ 作(Zuo)者(Zhe)：STEPHEN BARKER, AIDAN STARR, JEROEN VAN DER LUBBE et al.▲ 链(Lian)接(Jie)：https://www.science.org/doi/10.1126/science.abm4033▲ 摘(Zhai)要(Yao)：100万(Wan)年(Nian)前(Qian)，全(Quan)球(Qiu)冰(Bing)量(Liang)的(De)变(Bian)化(Hua)主(Zhu)要(Yao)是(Shi)倾(Qing)角(Jiao)的(De)变(Bian)化(Hua)；然(Ran)而(Er)，岁(Sui)差(Cha)产(Chan)生(Sheng)何(He)种(Zhong)作(Zuo)用(Yong)的(De)问(Wen)题(Ti)仍(Reng)然(Ran)没(Mei)有(You)解(Jie)决(Jue)。通(Tong)过(Guo)过(Guo)去(Qu)170万(Wan)年(Nian)的(De)北(Bei)大(Da)西(Xi)洋(Yang)冰(Bing)漂(Piao)流(Liu)记(Ji)录(Lu)，我(Wo)们(Men)发(Fa)现(Xian)特(Te)定(Ding)冰(Bing)川(Chuan)周(Zhou)期(Qi)（反(Fan)映(Ying)了(Liao)冰(Bing)盖(Gai)的(De)扩(Kuo)张(Zhang)）中(Zhong)冰(Bing)漂(Piao)流(Liu)起(Qi)始(Shi)通(Tong)常(Chang)持(Chi)续(Xu)在(Zai)倾(Qing)角(Jiao)较(Jiao)少(Shao)而(Er)大(Da)规(Gui)模(Mo)冰(Bing)消(Xiao)融(Rong)事(Shi)件(Jian)都(Du)与(Yu)岁(Sui)差(Cha)的(De)最(Zui)小(Xiao)值(Zhi)相(Xiang)关(Guan)。此(Ci)外(Wai)，我(Wo)们(Men)的(De)研(Yan)究(Jiu)结(Jie)果(Guo)表(Biao)明(Ming)，在(Zai)中(Zhong)-晚(Wan)更(Geng)新(Xin)世(Shi)时(Shi)期(Qi)，由(You)岁(Sui)差(Cha)驱(Qu)动(Dong)的(De)大(Da)规(Gui)模(Mo)消(Xiao)融(Rong)事(Shi)件(Jian)与(Yu)冰(Bing)消(Xiao)期(Qi)之(Zhi)间(Jian)普(Pu)遍(Bian)存(Cun)在(Zai)关(Guan)联(Lian)。在(Zai)增(Zeng)加(Jia)发(Fa)生(Sheng)前(Qian)，倾(Qing)角(Jiao)本(Ben)身(Shen)就(Jiu)足(Zu)以(Yi)结(Jie)束(Shu)一(Yi)次(Ci)冰(Bing)期(Qi)循(Xun)环(Huan)，在(Zai)约(Yue)100万(Wan)年(Nian)以(Yi)后(Hou)，随(Sui)着(Zhuo)北(Bei)半(Ban)球(Qiu)冰(Bing)原(Yuan)的(De)南(Nan)延(Yan)，倾(Qing)角(Jiao)失(Shi)去(Qu)了(Liao)对(Dui)冰(Bing)川(Chuan)消(Xiao)退(Tui)的(De)主(Zhu)导(Dao)作(Zuo)用(Yong)。▲ Abstract：Prior to ~1 million years ago (Ma), variations in global ice volume were dominated by changes in obliquity; however, the role of precession remains unresolved. Using a record of North Atlantic ice rafting spanning the past 1.7 million years, we find that the onset of ice rafting within a given glacial cycle (reflecting ice sheet expansion) consistently occurred during times of decreasing obliquity whereas mass ice wasting (ablation) events were consistently tied to minima in precession. Furthermore, our results suggest that the ubiquitous association between precession-driven mass wasting events and glacial termination is a distinct feature of the mid to late Pleistocene. Before then (increasing), obliquity alone was sufficient to end a glacial cycle, before losing its dominant grip on deglaciation with the southward extension of Northern Hemisphere ice sheets since ~1 Ma.Where rivers jump course河(He)流(Liu)“跳(Tiao)跃(Yue)”的(De)地(Di)方(Fang)▲ 作(Zuo)者(Zhe)：SAM BROOKE, AUSTIN J.

The controls on avulsion locations are poorly understood as a result of sparse data on such features. We analyzed nearly 50 years of satellite imagery and documented 113 avulsions across the globe that indicate three distinct controls on avulsion location. Avulsions on fans coincide with valley-confinement change, whereas avulsions on deltas are primarily clustered within the backwater zone, indicating a control by spatial flow deceleration or acceleration during floods. However, 38% of avulsions on deltas occurred upstream of backwater effects. These events occurred in steep, sediment-rich rivers in tropical and desert environments. Our results indicate that avulsion location on deltas is set by the upstream extent of flood-driven erosion, which is typically limited to the backwater zone but can extend far upstream in steep, sediment-laden rivers. Our findings elucidate how avulsion hazards might respond to land use and climate change.Models predict planned phosphorus load reduction will make Lake Erie more toxic模(Mo)型(Xing)预(Yu)测(Ce)计(Ji)划(Hua)中(Zhong)的(De)磷(Lin)负(Fu)荷(He)减(Jian)少(Shao)将(Jiang)使(Shi)伊(Yi)利(Li)湖(Hu)的(De)毒(Du)性(Xing)更(Geng)大(Da)▲ 作(Zuo)者(Zhe)：FERDI L.

We performed a large-scale meta-analysis including 103 papers and used it to develop a mechanistic, agent-based model of Microcystis growth and microcystin production. Simulations for Lake Erie suggest that the observed toxigenic-to-nontoxigenic strain succession during the 2014 Toledo drinking water crisis was controlled by different cellular oxidative stress mitigation strategies (protection by microcystin versus degradation by enzymes) and the different susceptibility of those mechanisms to nitrogen limitation. This model, as well as a simpler empirical one, predicts that the planned phosphorus load reduction will lower biomass but make nitrogen and light more available, which will increase toxin production, favor toxigenic cells, and increase toxin concentrations.
