| 1 | Higher alcohol synthesis over Cu-Fe composite oxides with high selectivity to C_(2+)OH显示文摘Cu-Fe composite oxides were prepared by co-precipitation method and tested for higher alcohol synthesis from syngas. The selectivity to C2+OH and C6+OH in alcohol distribution was very high while the methane product fraction in hydrocarbon distribution was rather low, demonstrating a promising potential in higher alcohols synthesis from syngas. The distribution of alcohols and hydrocarbons approximately obeyed Anderson-Schulz-Flory distribution with similar chain growth probability, indicating alcohols and hydrocarbons derived from the same intermediates. The effects of Cu/Fe molar ratio, reaction temperature and gas hourly space velocity (GHSV) on catalytic performance were studied in detail. The sample with a Cu/Fe molar ratio of 10/1 exhibited the best catalytic performance. Higher reaction temperature accelerated water-gas-shift reaction and led to lower total alcohols selectivity. GHSV showed great effect on catalytic performance and higher GHSV increased the total alcohol selectivity, indicating there existed visible dehydration reaction of alcohol into hydrocarbon. | Zhenghong Bao Kang Xiao Xingzhen Qi Xinxing Wang Liangshu Zhong Kegong Fang Minggui Lin Yuhan Sun | 2013 | Journal of Energy Chemistry2013，22，1： | 10 |
| 2 | Advances in direct production of value-added chemicals via syngas conversion显示文摘Syngas conversion to fuels and chemicals is one of the most challenging subjects in the field of C1 chemistry. It is considered as an attractive alternative non-petroleum-based production route. The direct synthesis of olefins and alcohols as high value-added chemicals from syngas has drawn particular attention due to its process simplicity, low energy consumption and clean utilization of carbon resource, which conforms to the principles of green carbon science. This review describes the recent advances for the direct production of lower olefins and higher alcohols via syngas conversion. Recent progress in the development of new catalyst systems for enhanced catalytic performance is highlighted. We also give recommendations regarding major challenges for further research in syngas conversion to various chemicals. | Yunlei An Tiejun Lin Fei Yu Yanzhang Yang Liangshu Zhong Minghong Wu Yuhan Sun | 2017 | Science China Chemistry2017，60，7： | 8 |

| 4 | Nuclear UHRF1 is a gate-keeper of cellular AMPK activity and function显示文摘The AMP-activated protein kinase(AMPK)is a central regulator of energy homeostasis.Although much has been learned on how low energy status and glucose starvation activate AMPK,how AMPK activity is properly controlled in vivo is still poorly understood.Here we report that UHRF1,an epigenetic regulator highly expressed in proliferating and cancer cells,interacts with AMPK and serves to suppress AMPK activity under both basal and stressed conditions.As a nuclear protein,UHRF1 promotes AMPK nuclear retention and strongly suppresses nuclear AMPK activity toward substrates H2B and EZH2.Importantly,we demonstrate that UHRF1 also robustly inhibits AMPK activity in the cytoplasm compartment,most likely as a consequence of AMPK nucleocytoplasmic shuttling.Mechanistically,we found that UHRF1 has no obvious effect on AMPK activation by upstream kinases LKB1 and CAMKK2 but inhibits AMPK activity by acting as a bridging factor targeting phosphatase PP2A to dephosphorylate AMPK.Hepatic overexpression of UHRF1 showed profound effects on glucose and lipid metabolism in wild-type mice but not in those with the liver-specific knockout of AMPKα1/α2,whereas knockdown of UHRF1 in adipose tissue led to AMPK activation and reduced sizes of adipocytes and lipogenic activity,highlighting the physiological significance of this regulation in glucose and lipid metabolism.Thus,our study identifies UHRF1 as a novel AMPK gate-keeper with critical roles in cellular metabolism. | Xiang Xu Guangjin Ding Caizhi Liu Yuhan Ding Xiaoxin Chen Xiaoli Huang Chen-Song Zhang Shanxin Lu Yunpeng Zhang Yuanyong Huang Zhaosu Chen Wei Wei Lujian Liao Shu-Hai Lin Jingya Li Wei Liu Jiwen Li Sheng-Cai Lin Xinran Ma Jiemin Wong | 2022 | Cell Research2022，32，1： | 3 |

| 11 | TeaPGDB:Tea Plant Genome Database显示文摘As the most widely consumed beverage in the world,tea has various nutritional,economic,and global cultural values.With the development of the third-generation sequencing technology,several genome sequences of tea plants have been published.These genomic data have pivotal information that is of benefit to tea plant breeders and biologists in advancing tea plant improvement and the final quality of tea products.We hereby present the integrative online database,Tea Plant Genome Database(TeaPGDB;http://gffzz33ea8dac98494cc2hvof0xvn6q6v96u6f.ffgz.tsg.suse.edu.cn/tea),which incorporates the published genome sequences of tea plants.The current release of TeaPGDB hosts published tea plant genome data with various online tools,including JBrowse,gene search,SSR search,BLAST.TeaPGDB also contains a download server,which provides access for the download of genome-related data and rich annotation files.TeaPGDB is committed to collecting,integrating,and annotating published tea plant genome data,providing data support for research on tea plant heredity,evolution,breeding for resistance,plant improvement,and facilitating the characterization of important traits or flavor related genes in the community.Compared with other tea plant databases,this database not only contains more complete genome data and gene annotation information,but also has a user-friendly interface for researchers in the field. | Xiaogang Lei Ya Wang Yuhan Zhou Yongzhong Chen Hongyuan Chen Zhongwei Zou Lin Zhou Yuanchun Ma Fei Chen Wanping Fang | 2021 | Beverage Plant Research2021，1，1： | 1 |
| 12 | The conservation patterns of grassland ecosystem in response to the forage-livestock balance in North China显示文摘Being a key ecological security barrier and production base for grassland animal husbandry in China,the balance between grassland forage supply and livestock-carrying pressure in North China directly affects grassland degradation and restoration,thereby impacting grassland ecosystem services.This paper analyzes the spatiotemporal variation in grassland vegetation coverage,forage supply,and the balance between grassland forage supply and livestock-carrying pressure from 2000 to 2015 in North China.We then discuss the spatial pattern of grassland ecological conservation under the impacts of grassland degradation and restoration,and livestock-carrying pressure.Over the last 16 years,the total grassland area in North China decreased by about 16,000 km^(2),with vegetation coverage degraded by 6.7%of the grasslands but significantly restored by another 5.4%of grasslands.The provisioning of forage by natural grassland mainly increased over time,with an annual growth rate of approximately 0.3 kg/ha,but livestock-carrying pressure also increased continuously.The livestock-carrying pressure index without any supplementary feeding reached as high as 3.8.Apart from the potential livestock-carrying capacity in northeastern Inner Mongolia and the central Tibetan Plateau,most regions in North China are currently overloaded.Considering the actual supplementary feeding during the cold season,the livestock-carrying pressure index is about 3.1,with the livestock-carrying pressure mitigated in central and eastern Inner Mongolia.Assuming full supplementary feeding in the cold season,livestock-carrying pressure index will fall to 1.9,with the livestock-carrying pressure alleviated significantly in Inner Mongolia and on the Tibetan Plateau.Finally,we propose different conservation and development strategies to balance grassland ecological conservation and animal husbandry production in different regions of protected areas,pastoral areas,farming-pastoral ecotone,and farming areas,according to the grassland ecological protection patterns. | HUANG Lin NING Jia ZHU Ping ZHENG Yuhan ZHAI Jun | 2021 | Journal of Geographical Sciences2021，31，4： | 1 |

| 14 | SiO_(2) nanofiber composite gel polymer electrolyte by in-situ polymerization for stable Li metal batteries显示文摘Gel polymer electrolytes(GPEs) are promising alternatives to liquid electrolytes applied in high-energydensity batteries.Here superior SiO_(2) nanofiber composite gel polymer electrolytes(SNCGPEs) are developed via in-situ ionic ring-opening polymerization of 1,3-dioxolane(DOL) monomers in SiO_(2) nanofiber membrane(PDOL-SiO_(2)) for lithium metal batteries.The oxygen atoms of PDOL together with Si-O of SiO_(2) construct a more efficient channel for Li^(+) migration.Consequently,the lithium ion transference number(t_(Li^(+)) and ionic conductivity(σ) at 30℃ of PDOL-SiO_(2) are 0.80 and 1.68×10^(-4)S/cm separately.PDOL-SiO_(2) manifests the electrochemical decomposition potentials of 4.90 V.At 0.5 mA/cm^(2),Li|PDOL-SiO_(2) |Li cell shows a steady cycling performance for nearly 1400 h.LFP|PDOL-SiO_(2) |Li battery can steadily cycle at 0.5 C with a capacity retention rate of 89% after 200 cycles.While cycling at 2 C,the capacity retention rate can maintain at 78% after 300 cycles.This contribution provides a innovative strategy for accelerating Li^(+)transportation via designing PDOL molecular chains throughout the SiO_(2) nanofiber framework,which is crucial for high-energy-density LMBs. | Zhichuan Shen Jiawei Zhong Jiahong Chen Wenhao Xie Kun Yang Yuhan Lin Jinbiao Chen Zhicong Shi | 2023 | Chinese Chemical Letters2023，34，3： | 1 |
| 15 | Research progress on vanadium oxides for potassium-ion batteries显示文摘Potassium-ion batteries(PIBs)have been considered as promising candidates in the post-lithium-ion battery era.Till now,a large number of materials have been used as electrode materials for PIBs,among which vanadium oxides exhibit great potentiality.Vanadium oxides can provide multiple electron transfers during electrochemical reactions because vanadium possesses a variety of oxidation states.Meanwhile,their relatively low cost and superior material,structural,and physicochemical properties endow them with strong competitiveness.Although some inspiring research results have been achieved,many issues and challenges remain to be further addressed.Herein,we systematically summarize the research progress of vanadium oxides for PIBs.Then,feasible improvement strategies for the material properties and electrochemical performance are introduced.Finally,the existing challenges and perspectives are discussed with a view to promoting the development of vanadium oxides and accelerating their practical applications. | Yuhan Wu Guangbo Chen Xiaonan Wu Lin Li Jinyu Yue Yinyan Guan Juan Hou Fanian Shi Jiyan Liang | 2023 | Journal of Semiconductors2023，44，4： | 1 |

| 19 | Two chemical mutagens modulate the seed germination,growth,and phenotypic characteristics of Chinese fir(Cunninghamia lanceolata)显示文摘Chinese fir(Cunninghamia lanceolata(Lamb.)Hook),a fast-growing and economically important timber tree species in China,is widely used in construction,furniture,and paper manufacture but has a long breeding cycle.Chemical mutagens,such as ethyl methane sulfonate(EMS)and sodium azide(SA),are widely used in crops such as rice,wheat,cotton,soybean and sugarcane but their utility for tree breeding is unknown.In this study we examined the effects of EMS and S A on Chinese fir seed germination and growth.Chinese fir seeds were treated with the two chemical mutagens;were planted in Jiangle County,Fujian Province,China;and their heights were measured from 2011 to2017.The concentrations and durations of treatment with the two chemical mutagens were significantly associated with the Chinese fir seedling and mortality rates,as well as with the heights of trees from the seedling stage to 3 years old.We also generated 127 mutants with abnormal branches and reproductive growth.We report here the effects of two chemical mutagens on Chinese fir breeding;our data will contribute to knowledge of the utility of EMS and SA in forestry. | Sen Cao Ruiyang Hu Xialei Wu Yuhan Sun Bo Wu Hongjing Duan Huazhong Lin Mingjing Wu Luming Fang Xiaolong Yu Wei Wu Yun Li | 2021 | Journal of Forestry Research2021，32，5： | 0 |
| 20 | Regioselective electrochemical radical cascade cyclization of internal alkynes to selenated and trifluoromethylated dihydropyran显示文摘Dihydropyran(DHP)compounds are not only found in natural products and bioactive molecules,but also serve as important precursors in organic synthesis.Nonetheless,traditional methods for the construction of such compounds are usually limited to disubstituted DHPs.To address this synthetic challenge,reported here is an efficient electrochemical strategy toward the selenated and trifluoromethylated DHP compounds.The reaction proceeded smoothly under mild electrolysis conditions.The broad substrate scope(>50 examples)and scalable synthesis demonstrated the complexity-building potential of the strategy.Initial mechanistic studies reveal that cyclization may involve a radical process.This protocol may promote the further development of diversified synthesis of multi-substituted dihydropyran. | Mingming Yu Tiantian Huang Lin Zhang Muhammad Shabbir Yuhan Gao Yi-Hung Chen Hong Yi Aiwen Lei | 2023 | Science China Chemistry2023，66，11： | 0 |
