We used x-ray photoelectron spectroscopy at 180 to 500 millibar to probe the nature of Zn and reaction intermediates during CO2/CO hydrogenation over Zn/ZnO/Cu(211), where the temperature is sufficiently high for the reaction to rapidly turn over, thus creating an almost adsorbate-free surface. Tuning of the grazing incidence angle makes it possible to achieve either surface or bulk sensitivity. Hydrogenation of CO2 gives preference to ZnO in the form of clusters or nanoparticles, whereas in pure CO a surface Zn-Cu alloy becomes more prominent. The results reveal a specific role of CO in the formation of the Zn-Cu surface alloy as an active phase that facilitates efficient CO2methanol synthesis.Highly efficient catalytic production of oximes from ketones using in situ–generated H2O2yuanweihechengguoyanghuaqingshixiannilongdantidegaoxiaohecheng▲ zuozhe：RICHARD J.

The ammoximation of several additional simple ketones is also demonstrated. Our approach eliminates the need to transport and store highly concentrated, stabilized H2O2, potentially achieving substantial environmental and economic savings. This approach could form the basis of an alternative route to numerous chemical transformations that are currently dependent on a combination of preformed H2O2and TS-1, while allowing for considerable process intensification.wuliPhysicsTunable and state-preserving frequency conversion of single photons in hydrogenqingzhongdangeguangzidekediaoxiehezhuangtaibaochidepinlvzhuanhuan▲ zuozhe：R.

Most current approaches offer only very small frequency shifts and limited tunability, while suffering from high insertion loss and Raman noise originating in the materials used. We introduce a route to quantum-correlation–preserving frequency conversion using hydrogen-filled antiresonant-reflecting photonic crystal fibers. Transient optical phonons generated by stimulated Raman scattering enable selective frequency up-conversion by 125 terahertz of the idler photon of an entangled pair, with efficiencies up to 70%. This threshold-less molecular modulation process preserves quantum correlations, making it ideal for applications in quantum information.cailiaokexueMaterials ScienceEmergent ferroelectricity in subnanometer binary oxide films on siliconguishangjichengdeyanamieryuanyanghuawubaomozhongdetiedianxing▲ zuozhe：SURAJ S.

We report on the thickness-dependent antiferroelectric-to-ferroelectric phase transition in zirconium dioxide (ZrO2) thin films on silicon. The emergent ferroelectricity and hysteretic polarization switching in ultrathin ZrO2, conventionally a paraelectric material, notably persists down to a film thickness of 5 angstroms, the fluorite-structure unit-cell size. This approach to exploit three-dimensional centrosymmetric materials deposited down to the two-dimensional thickness limit, particularly within this model fluorite-structure system that possesses unconventional ferroelectric size effects, offers substantial promise for electronics, demonstrated by proof-of-principle atomic-scale nonvolatile ferroelectric memory on silicon. Additionally, it is also indicative of hidden electronic phenomena that are achievable across a wide class of simple binary materials.diqiukexueEarth ScienceA dynamic saline groundwater system mapped beneath an Antarctic ice streamnanjibingliuxiadongtaidehanyandixiashuixitong▲ zuozhe：CHLOE D.

Current knowledge of these water systems is limited to the shallow portions near the ice-bed interface, but hypothesized deeper groundwater could also influence ice streaming. Here, we use magnetotelluric and passive seismic data from Whillans Ice Stream, West Antarctica, to provide the first observations of deep sub–ice stream groundwater. Our data reveal a volume of groundwater within a >1-kilometer-thick sedimentary basin that is more than an order of magnitude larger than the known subglacial system. A vertical salinity gradient indicates exchange between paleo seawater at depth and contemporary basal meltwater above. Our results provide new constraints for subglacial water systems that affect ice streaming and subglacial biogeochemical processes.A stronger role for long-term moisture change than for CO2 in determining tropical woody vegetation changechangqishuifenbianhuazaijuedingredaimubenzhibeibianhuafangmianbieryanghuatandezuoyonggengda▲ zuozhe：WILLIAM D.

The effect of eCO2 is built into Earth system models, although testing the relationship over long periods remains challenging. Here, we explore the relative importance of six drivers of vegetation change in western Africa over the past ~500,000 years (moisture availability, fire activity, mammalian herbivore density, temperature, temperature seasonality, CO2) by coupling past environmental change data from Lake Bosumtwi (Ghana) with global data. We found that moisture availability and fire activity were the most important factors in determining woody cover, whereas the effect of CO2 was small. Our findings suggest that the role of eCO2 effects on tropical vegetation in predictive models must be reconsidered.guiyuanganshibijiaoguideyizhongshuiguogan，danshizaigui，woduhuimailaorenmaishang2jin，yinweiguiyuanzhonghanyoudaliangde“tie、gai、duozhonganjisuan、duozhongweishengsu”dengyingyangwuzhi，jingchangchiguiyuangan，keyibuzuqixue，shiwomenjingqishengenghao，tebieshizainvren，zaiyanredexiatian，duochiyixieguiyuangan，keyibashentiyanghao，dengtianlenghou，shoujiaobuzaibingliangliao。suiranguiyuanganyingyangjiazhigao，danshibuyiguoliangshiyong，meitianchi10keguiyuanganjike，chiduoliaoyishanghuohuoyoufatangniaobing。
