1Primary dolostone related to the Cretaceous lacustrine hydrothermal sedimentation in Qingxi sag, Jiuquan Basin on the northern Tibetan Plateau显示文摘Based on comprehensive studies in petrography,petrofabric analysis and geochemistry,this paper describes a unique and rare laminated micritic ferruginous primary dolostone crystallized and precipitated from the alkaline hot brine under the conditions of the Mesozoic faulted lake basin.The main rock-forming mineral of this dolostone is ferruginous dolomite with a micritic structure.This dolomite mostly exhibits laminae of 0.1–1 mm thick and is often discovered with other minerals,such as albite,analcite,barite and dickite,which have at least two types of interbedded laminae.Petrogeochemistry reveals that this dolostone contains a large number of typomorphic elements of hydrothermal sedimentation,including Sb,Ba,Sr,Mn,and V.In addition,the LREE is in relatively high concentrations and possesses the typical REE distribution pattern with negative Eu anomaly.Oxygen isotope values(δ18OPDB)range from 5.89‰to 14.15‰with an average of 9.69‰.The ratio of87Sr/86Sr is between0.711648 and 0.719546,with an average of 0.714718.These data indicate that the depositional environment is a stable,blocked,anoxic low-lying hot brine pool in the bottom of deep lake controlled by basement faults.The hydrothermal fluid is the alkaline hot brine formed by the combination of the infiltration lake water and mantle-derived magmatic water,consisting of many ions,including Ca2+,Mg2+and Fe2+.Under the driving flow power of magmatic heat,gravity and compaction,the hydrothermal fluid overcame the overburden pressure and hydrostatic pressure of the lake water body,and boiled to explosion,and then the explosion shattered the original laminated micritic ferruginous primary dolostone near the vent and then formed a new type of dolostone called shattered'hydroexplosion breccias'.In the low-lying,unperturbed hot brine pool,far from the vent,the laminated micritic ferruginous primary dolostone was quickly crystallized and chemicals precipitated from the hydrotherm.This study of special rocks contributes to research into the causes of the formation of lacustrine carbonate rocks and dolostone.In particular,it provides new examples and research insights for future studies of the lacustrine dolomite from the similar Mesozoic and Cenozoic basins in China.WEN HuaGuo ZHENG RongCai QING HaiRuo FAN MingTao LI YanAn GONG BoShi 2013Science China Earth Sciences2013,56,12:12
2MoS2 nanorods with inner caves through synchronous encapsulation of sulfur for high performance Li–S cathodes显示文摘Lithium–sulfur(Li–S)batteries have become one of the most promising candidates for next-generation batteries owing to their high specific capacity,low cost,and environment-friendliness.Many efforts have been made to mitigate the'shuttle effect'through physical adsorption and chemical bonding.MoS2 has been proposed as a cathode material to provide effective anchoring sites for lithium polysulfides(Li PSs),but is still limited by its layer structure.Herein,we designed novel MoS2 nanorods with inner caves based on our previous work,and performed synchronous encapsulation of sulfur during the synthesis process.The outer MoS2 tubular shells physically inhibit the outward diffusion of polysulfide species while the inner particles chemically anchor the polysulfides to prevent shuttling.As the cathode matrix in Li–S batteries,the electrochemical results deliver a high initial discharge capacity of 1213 mAhg^-1 for sulfur at 0.1 C.After cycling at 1 C for 300 cycles,the cells exhibit a capacity decay of only 0.076%per cycle and high average coulombic efficiency over 95%.The tubular MoS2 structure is an innovative and appealing design,which could be regarded as a prospective substrate for the improved performance of Li–S batteries.Yikun Yi Zechen Liu Pu Yang Tao Wang Xuewen Zhao Hongyang Huang Yonghong Cheng Jinying Zhang Mingtao Li 2020Journal of Energy Chemistry2020,29,6:5
3Optically spatial information selection with hybridly polarized beam in atomic vapor显示文摘Vector beams with spatially variant polarization have attracted much attention in recent years, with potential applications in both classical optics and quantum optics. In this work, we study a polarization selection of spatial intensity distribution by utilizing a hybridly polarized beam as a coupling beam and a circularly polarized beam as a probe beam in87 Rb atom vapor. We experimentally observe that the spatial intensity distribution of the probe beam after passing through atoms can be modulated by the hybridly polarized beam due to the optical pumping effect. Then, the information loaded in the probe beam can be designedly filtrated by an atomic system with a high extinction ratio. A detailed process of the optical pumping effect in our configurations and the corresponding absorption spectra are presented to interpret our experimental results, which can be used for the spatial optical information locally extracted based on an atomic system, which has potential applications in quantum communication and computation.JINWEN WANG XIN YANG YUNKE Li YUN CHEN MINGTAO CAO DONG WEI HONG GAO FUU LI 2018Photonics Research2018,6,5:5

6The role of fluorescent carbon dots in crops:Mechanism and applications显示文摘Fluorescent carbon dots(CDs)have been widely studied in biosensing,imaging,information encryption,and optoelectronic devices due to excellent optical properties,such as photostability,tunable luminescence range,and resistance to photobleaching.In recent years,CDs have been explored for use in agriculture.Based on their light harvest and light conversion capacity,as well as their characteristics of easy synthesis and low toxicity,CDs show great potential in improving crop photosynthesis.In addition,CDs can also be used for smart and anticounterfeiting packing,food safety detection,and preservation of crops after harvest.In this study,the application of CDs with excellent optical properties in crops has been summarized,including preharvest processes(photosynthesis and plant imaging),and postharvest processes(crop preservation and food safety).Then the toxicity of CDs to crops is introduced.Finally,the present challenges and future prospects are discussed.Baoyan Guo Guo Liu Haopeng Wei Jiemin Qiu Jianle Zhuang Xuejie Zhang Mingtao Zheng Wei Li Haoran Zhang Chaofan Hu Bingfu Lei Yingliang Liu 2022SmartMat2022,3,2:2
7Towards carbon neutrality:A study on China's long-term low-carbon transition pathways and strategies显示文摘As the world's biggest carbon dioxide(CO_(2))emitter and the largest developing country,China faces daunting challenges to peak its emissions before 2030 and achieve carbon neutrality within 40 years.This study fully considered the carbon-neutrality goal and the temperature rise constraints required by the Paris Agreement,by developing six long-term development scenarios,and conducting a quantitative evaluation on the carbon emissions pathways,energy transformation,technology,policy and investment demand for each scenario.This study combined both bottom-up and top-down methodologies,including simulations and analyses of energy consumption of end-use and power sectors(bottom-up),as well as scenario analysis,investment demand and technology evaluation at the macro level(top-down).This study demonstrates that achieving carbon neutrality before 2060 translates to significant efforts and overwhelming challenges for China.To comply with the target,a high rate of an average annual reduction of CO_(2) emissions by 9.3%from 2030 to 2050 is a necessity,which requires a huge investment demand.For example,in the 1.5℃ scenario,an investment in energy infrastructure alone equivalent to 2.6%of that year's GDP will be necessary.The technological pathway towards carbon neutrality will rely highly on both conventional emission reduction technologies and breakthrough technologies.China needs to balance a long-term development strategy of lower greenhouse gas emissions that meets both the Paris Agreement and the long-term goals for domestic economic and social development,with a phased implementation for both its five-year and long-term plans.Jiankun He Zheng Li Xiliang Zhang Hailin Wang Wenjuan Dong Ershun Du Shiyan Chang Xunmin Ou Siyue Guo Zhiyu Tian Alun Gu Fei Teng Bin Hu Xiu Yang Siyuan Chen Mingtao Yao Zhiyi Yuan Li Zhou Xiaofan Zhao Ying Li Danwei Zhang 2022Environmental Science and Ecotechnology2022,,1:2

11Anchoring Single Nickel Atoms on Carbon-vacant Carbon Nitride Nanosheets for Efficient Photocatalytic Hydrogen Evolution显示文摘Polymeric carbon nitride(PCN)has emerged as a promising candidate for photocatalytic hydrogen evolution,but its dependence on scarce and high-cost noble metal co-catalysts severely limits its extensive application.It will be of great promise to develop non-noble metal single-atom co-catalysts with low-cost and high atom utilization to improve the photocatalytic performance over PCN.Herein,single Ni atoms are successfully anchored onto carbon-vacant PCN nanosheets(CCN-SANi)via a two-step ammonia thermal treatment and photo-deposition process.Theoretical calculations and experimental results demonstrate that the optical absorption property and the charge transfer ability of CCN-SANi have been significantly improved with the introduction of single Ni atoms to form Ni-N3 sites.In comparison to carbon-vacant PCN(CCN)loaded with Ni clusters,the obtained CCN-SANi exhibits 11.4 times increased photocatalytic performance,with the highest hydrogen evolution rate reaching 511μmol/(g·h),which is even 1.7 times higher than that of CCN loaded with Pt clusters.This research proposes an inspiring and reliable strategy to design novel single-atom semiconducting polymers with electronic structures manipulated for efficient photocatalysis.LIN Zhi ZHANG Zhengqi WANG Yiqing PENG Zhiming WANG Xinxin WANG Ruizhe HUANG Yu-Cheng MENG Fanqi LI Mingtao DONG Chung-Li ZHANG Qinghua GU Lin SHEN Shaohua 2022Chemical Research in Chinese Universities2022,38,5:1

15Lowing the energy loss of organic solar cells by molecular packing engineering via multiple molecular conjugation extension显示文摘The central unit(benzo[c][1,2,5]thiadiazole) in Y6 series of molecules plays a determining role in their unique intermolecular packing for a three-dimensionally(3D) network, largely endowing their organic solar cells(OSCs) with so far the best power conversion efficiencies(PCEs) and also largely suppressed energy losses(Eloss). Despite its vital role in molecular packing, very few explorations for central unit have been conducted due to possibly the constructing challenge of central heterocyclic units.Herein, a highly efficient acceptor-donor-acceptor(A-D-A) type electron acceptor, CH17, has been designed and constructed,featured with a prominent π extension in both directions of the central and end units with respect to Y6 series. Such a multiple and much enhanced conjugation extension in CH17 enables a much more effective and compact 3D molecular packing compared with that of Y6 supported by X-ray single crystal and other analysis, mainly caused by a newly observed distinctive dual “end unit to central unit” packing mode. This much favorable molecular packing, also kept in its blends with donor materials, leads a larger electron and hole transfer integrals and hence much improved charge transport, and reduced energetic disorders in CH17blends. More importantly, the observed upshifted charge transfer(CT) state of CH17 blends compared with that of Y6, due to its increased molecular conjugation extension in both directions, further enhances the hybridization between its CT and local exciton(LE) states, resulting in higher luminescence efficiency, much suppressed non-radiative recombination loss and smaller Elosswith respect to that of Y6. Consequently, an excellent PCE of 17.84% is achieved with PM6 as the donor in a binary device compared with a PCE of 16.27% for the controlled Y6 device. Furthermore, a further improved PCE of 18.13% is achieved by CH17-based ternary single-junction OSCs along with a markedly reduced Elossof 0.49 e V and larger open-circuit voltage(Voc) of0.89 V, compared with that(16.27% of PCE, 0.85 V of Voc, and 0.53 e V of Eloss) of the control device using Y6. This significantly improved photovoltaic performance caused by molecular multiple conjugation extension, especially through the largely unexplored central unit, indicates that there is still much room to further enhance OSC performance by addressing the most important issue for OSC, i.e, the smaller Voccaused by larger Eloss, through engineering molecular packing by designing/tuning molecule more dedicatedly.Hongbin Chen Yalu Zou Huazhe Liang Tengfei He Xiaoyun Xu Yunxin Zhang Zaifei Ma Jing Wang Mingtao Zhang Quanwen Li Chenxi Li Guankui Long Xiangjian Wan Zhaoyang Yao Yongsheng Chen 2022Science China Chemistry2022,65,7:1
