| 1 | Processing of advanced thermoelectric materials显示文摘Last two decades have witnessed significant progress in thermoelectric research,to which materials processing has crucial contributions.Compared with traditional zone-melting method used for fabricating bismuth telluride alloys,new powder-based processes have more freedom for manipulating nanostructures and nanocomposites.Thermoelectric performance enhancement is realized in most thermoelectric materials by introducing fine-grained and nano-composite structures with accurately controlled compositions.This review gives a comprehensive summary on the processing aspects of thermoelectric materials with three focuses on the powder synthesis,advanced sintering process and the formation of nano structures in bulk materials. | LI JingFeng PAN Yu WU ChaoFeng SUN FuHua WEI TianRan | 2017 | Science China(Technological Sciences)2017，60，9： | 13 |
| 2 | Forms and Balance of Nitrogen and Phosphorus in Cage Culture Waters in Guangdong Province, China显示文摘In order to approach the characteristics of nitrogen and phosphorus pollution caused by cage culture and the balance of nitrogen and phosphorus during the process of cage culture, a monitoring was conducted in Daya Bay of Guangdong Province, China from April 2002 to Jane 2003. The results show that the concentrations of total nitrogen (TN) in the waters at the sites with five and ten years of cage culture history are 1.8 and 2.3 times of that at control site respectively. Ammonium (NH3-N) is the main form of nitrogen in spring while nitrate ( NO3 -) in winter. The concentrations of TN, total dissolved nitrogen (TDN) and dissolved organic nitrogen (DON) are highest in autumn. The concentration of phosphorus increases with the increasing of the culturing time, among which phosphate ( PO 34-) increases most obviously. The concentrations of total phosphorus (TP) and total dissolved phosphorus (TDP) are highest in autumn. The nitrogen and phosphorus are accumulated significantly in the sediment of cage culture area. The model of N balance in the cage culture area: bait (70.62%) + fry (0.28%) + input by tide (14.8%) + release from sediment (14.3%) = harvest of adult fish (12.07%) + deposition into sediment (28.75%) + output by tide (56.18%) + others (3.00%). The model of P balance: bait (83.11%) + fry (0.17%) + input by tide (12.23%) + release from sediment (4.49%) = harvest of adult fish (8.43%) + deposition into sediment (48.59%) + output by tide (41.94%) + others (1.04%). In one fish growth year, the contents of nitrogen and phosphorus in harvest of adult fish are only 17.0% and 10.1% of the contents of nitrogen and phosphorus in fish bait and fry, wherein 83% of nitrogen and more than 89% of phosphorus in fish bait became marine pollutants. | WEN Yanmao WEI Xiange SHU Tingfei ZHOU Jingfeng YU Guanghui LI Feng HUANG Yanyun | 2007 | Chinese Geographical Science2007，17，4： | 9 |
| 3 | Kinetics of the hydrogen absorption and desorption processes of hydrogen storage alloys: A review显示文摘High hydrogen absorption and desorption rates are two significant index parameters for the applications of hydrogen storage tanks.The analysis of the hydrogen absorption and desorption behavior using the isothermal kinetic models is an efficient way to investigate the kinetic mechanism.Multitudinous kinetic models have been developed to describe the kinetic process.However,these kinetic models were de-duced based on some assumptions and only appropriate for specific kinetic measurement methods and rate-controlling steps(RCSs),which sometimes lead to confusion during application.The kinetic analysis procedures using these kinetic models,as well as the key kinetic parameters,are unclear for many researchers who are unfamiliar with this field.These problems will prevent the kinetic models and their analysis methods from revealing the kinetic mechanism of hydrogen storage alloys.Thus,this review mainly focuses on the summarization of kinetic models based on different kinetic measurement methods and RCSs for the chemisorption,surface penetration,diffusion of hydrogen,nucleation and growth,and chemical reaction processes.The analysis procedures of kinetic experimental data are expounded,as well as the effects of temperature,hydrogen pressure,and particle radius.The applications of the kinetic models for different hydrogen storage alloys are also introduced. | Qian Li Xi Lin Qun Luo Yuʼan Chen Jingfeng Wang Bin Jiang Fusheng Pan | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，1： | 9 |
| 4 | Seismic Sedimentology Interpretation Method of Meandering Fluvial Reservoir:From Model to Real Data显示文摘Reservoir architecture of meandering river deposition is complex and traditional seismic facies interpretation method cannot characterize it when layer thickness is under seismic vertical resolution.In this study,a seismic sedimentology interpretation method and workflow for point bar characterization is built.Firstly,the influences of seismic frequency and sandstone thickness on seismic reflection are analyzed by outcrop detection with ground penetrating radar(GPR) and seismic forward modeling.It is found that(1) sandstone thickness can influence seismic reflection of point bar architecture.With the increasing of sandstone thickness from 1/4 wavelength(λ) to λ/2,seismic reflection geometries various from ambiguous reflection,'V' type reflection to 'X' type reflection;(2) seismic frequency can influence reservoirs' seismic reflection geometry.Seismic events follow inclined lateral aggradation surfaces,which is isochronic depositional boundaries,in high frequency seismic data while the events extend along lithologic surfaces,which are level,in low frequency data.Secondly,strata slice interpretation method for thin layer depositional characterization is discussed with seismic forward modeling.Lastly,a method and workflow based on the above study is built which includes seismic frequency analysis,90 o phasing,stratal slicing and integrated interpretation of slice and seismic profile.This method is used in real data study in Tiger shoal,the Gulf of Mexico.Two episodes of meandering fluvial deposition is recognized in the study layer.Sandstone of the lower unit,which is formed in low base level stage,distributes limited.Sandstone distribution dimension and channel sinuosity become larger in the upper layer,which is high base level deposition. | Tao Zhang Xianguo Zhang Chengyan Lin Jingfeng Yu Shouxiu Zhang | 2015 | Journal of Earth Science2015，26，4： | 8 |
| 5 | Development of integrated two-stage thermoelectric generators for large temperature difference显示文摘Multi-stage thermoelectric(TE) modules can withstand a large temperature difference and can be used to obtain a high conversion efficiency. In this study, two-stage PbTe/Bi2Te3 TE modules were developed with an enhanced efficiency through a comprehensive study of device structure design, module fabrication, and performance evaluation. PbTe-based AgPbmSbTem+2(abbreviated as LAST) is a typically high ZT material, while the corresponding TE module was rarely reported so far. How to utilize LAST to fabricate high efficiency TE modules therefore remains a central problem. Finite element simulation indicates that the temperature stability of the two-stage module for LAST is better than that of two-segmented module. Compared to Cu,Ni, and Ni-Fe alloys, Co-Fe alloy is an effective metallization layer for PbTe due to its low contact resistance and thin diffusion layer. By sintering a slice of Cu on TE legs, pure tinfoil can be used as a common welding method for mid-temperature TE modules. A maximum efficiency(ηmax) of 9.5% was achieved in the range of 303 to 923 K in an optimized PbTe/Bi2Te3 based two-stage module, which was almost twice that of a commercial TE module. | PEI Jun LI LiangLiang LIU DaWei ZHANG BoPing XIAO Yu LI JingFeng | 2019 | Science China(Technological Sciences)2019，62，9： | 6 |
| 6 | Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC. | Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 无 | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 4 |
| 7 | Development of a novel RNAi therapy:Engineered miR-31 exosomes promoted the healing of diabetic wounds显示文摘Rationale:Chronic wounds associated with diabetes exact a heavy burden on individuals and society and do not have a specific treatment.Exosome therapy is an extension of stem cell therapy,and RNA interference(RNAi)-based therapy is a type of advanced precision therapy.Based on the discovery of chronic wound-related genes in diabetes,we combined exosome therapy and RNAi therapy through an engineering approach for the treatment of diabetic chronic wounds.Methods:We combined exosome therapy and RNAi therapy to establish a precision therapy for diabetes-associated wounds via an engineered exosome approach.Results:First,chronic diabetic wounds express low levels of miR-31-5p compared with nondiabetic wounds,and an miR-31-5p mimic was shown to be effective in promoting the proliferation and migration of three wound-related cell types in vitro.Second,bioinformatics analysis,luciferase reporter assays and western blotting suggested that miR-31-5p promoted angiogenesis,fibrogenesis and reepithelization by inhibiting factor-inhibiting HIF-1(HIF1AN,also named FIH)and epithelial membrane protein-1(EMP-1).Third,engineered miR-31 exosomes were generated as a miR-31-5p RNAi therapeutic agent.In vivo,the engineered miR-31 exosomes promoted diabetic wound healing by enhancing angiogenesis,fibrogenesis and reepithelization.Conclusion:Engineered miR-31 exosomes are an ideal disease pathophysiology-initiated RNAi therapeutic agent for diabetic wounds. | Jinghuan Huang Muyu Yu Wenjing Yin Bo Liang Ang Li Jingfeng Li Xiaolin Li Shichang Zhao Fang Liu | 2021 | Bioactive Materials2021，6，9： | 3 |
| 8 | A CRISPR/Cas12a-empowered surface plasmon resonance platform for rapid and specific diagnosis of the Omicron variant of SARS-CoV-2显示文摘The outbreak of the COVID-19 pandemic was partially due to the challenge of identifying asymptomatic and presymptomatic carriers of the virus,and thus highlights a strong motivation for diagnostics with high sensitivity that can be rapidly deployed.On the other hand,several concerning SARS-CoV-2 variants,including Omicron,are required to be identified as soon as the samples are identified as‘positive’.Unfortunately,a traditional PCR test does not allow their specific identification.Herein,for the first time,we have developed MOPCS(Methodologies of Photonic CRISPR Sensing),which combines an optical sensing technology-surface plasmon resonance(SPR)with the‘gene scissors’clustered regularly interspaced short palindromic repeat(CRISPR)technique to achieve both high sensitivity and specificity when it comes to measurement of viral variants.MOPCS is a low-cost,CRISPR/Cas12a-systemempowered SPR gene-detecting platform that can analyze viral RNA,without the need for amplification,within 38 min from sample input to results output,and achieve a limit of detection of 15 fM.MOPCS achieves a highly sensitive analysis of SARS-CoV-2,and mutations appear in variants B.1.617.2(Delta),B.1.1.529(Omicron)and BA.1(a subtype of Omicron).This platform was also used to analyze some recently collected patient samples from a local outbreak in China,identified by the Centers for Disease Control and Prevention.This innovative CRISPR-empowered SPR platform will further contribute to the fast,sensitive and accurate detection of target nucleic acid sequences with single-base mutations. | Zhi Chen Jingfeng Li Tianzhong Li Taojian Fan Changle Meng Chaozhou Li Jianlong Kang Luxiao Chai Yabin Hao Yuxuan Tang Omar AAl-Hartomy Swelm Wageh Abdullah GAl-Sehemi Zhiguang Luo Jiangtian Yu Yonghong Shao Defa Li Shuai Feng William J.Liu Yaqing He Xiaopeng Ma Zhongjian Xie Han Zhang | 2022 | National Science Review2022，9，8： | 3 |
| 9 | Influence of Ni interlayer on interfacial microstructure and mechanical properties of Ti-6Al-4V/AZ91D bimetals fabricated by a solid–liquid compound casting process显示文摘The solid–liquid compound casting of Mg-AZ91D and Ti-TC4 alloys was developed by using pure Ni electro-deposited coating.The pouring temperatures of 660℃,690℃,720℃and 750℃were chosen to investigated the effects of casting temperatures on microstructural evolution,properties,and fracture behaviors of Ni-coated TC4/AZ91D bimetals by the solid–liquid compound casting(SLCC).The scanning electron microscopy(SEM)and the energy dispersive spectroscopy(EDS)results showed that the interfacial zone mainly composed of nickel,Mg_(2)Ni and Mg-Al-Ni in the bimetals cast at 660℃.As the pouring temperature was increased to 750℃,the width of the interface zone,which mainly composed ofδ(Mg),Mg_(2)Ni,Mg-Al-Ni,Mg_(3)TiNi_(2) and Al_(3)Ni,gradually increased.The microhardness tests showed that the micro-hardness of the interface zone was smaller than that of TC4 substrate but larger than that of the cast AZ91D matrix.At the pouring temperature of 720℃,the Ni-coated TC4/AZ91D bimetals had the most typical homogeneous interface,which had granular Mg-Al-Ni ternary phase but no ribbon-like Al3Ni binary phase,and achieved the highest shear strength of 97.35MPa.Meanwhile,further fracture behavior analysis showed that most fracture failure of Ni-coated TC4/AZ91D bimetals occurred at the Mg_(2)Ni+δ(Mg)eutectic structure and Al_(3)Ni hard intermetallic. | Fulin Wen Jianhua Zhao Miaowang Yuan Jingfeng Wang Dengzhi Zheng Jinyong Zhang Ke He Jingjing Shangguan Yu Guo | 2021 | Journal of Magnesium and Alloys2021，9，4： | 3 |
| 10 | Clear mortality gap caused by graft macrosteatosis in Chinese patients after cadaveric liver transplantation显示文摘Background:Liver transplantation(LT)is one of the most effective surgical treatment for patients with end-stage liver disease.Steatosis is a contributor for inferior graft quality.But its impact and safety on transplantation was less assessed in Chinese patients.Methods:Graft steatosis and related information involved in recipients,donors and surgical procedures were retrospectively collected from 239 patients.Results:Donor macrosteatosis(MaS)caused about 2.14 and 2.80 folds of increment on patient and graft mortality.Dose-response analysis revealed prominent risk of grafts on overall patient/organ mortality when MaS content exceeded 10%(P<0.05).Noteworthy,deaths were only observed in MaS group when concurrent with extremely higher post-transplant alanine aminotransferase(ALT,64%).However,microsteatosis(MiS)grafts didn’t affect outcomes after LT.In a cohort of Chinese patients,MaS had comprehensive effects on post-transplant outcomes with relatively lower safety threshold at 10%.Mortality gap caused by MaS grafts was observed in patients with severer ischemia reperfusion injury.Conclusions:Our study revealled the graft MaS affected the post-transplant outcomes in lower risk cutoff in Chinese patients.Further study is worthy to validate these results and investigate inner mechanism under the phenomenon. | Zhengtao Liu Wenchao Wang Li Zhuang Jingfeng Liu Shuping Que Dan Zhu Linfang Dong Jian Yu Lin Zhou Shusen Zheng | 2020 | Hepatobiliary Surgery and Nutrition2020，9，6： | 2 |
| 11 | CRISPR-Cas12a-Empowered Electrochemical Biosensor for Rapid and Ultrasensitive Detection of SARS-CoV-2 Delta Variant显示文摘Coronavirus disease 2019(COVID-19)is a highly contagious disease caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).The gold standard method for the diagnosis of SARS-CoV-2 depends on quantitative reverse transcription-polymerase chain reaction till now,which is time-consuming and requires expensive instrumentation,and the confirmation of variants relies on further sequencing techniques.Herein,we first proposed a robust technique-methodology of electrochemical CRISPR sensing with the advantages of rapid,highly sensitivity and specificity for the detection of SARS-CoV-2 variant.To enhance the sensing capability,gold electrodes are uniformly decorated with electro-deposited gold nanoparticles.Using DNA template identical to SARS-CoV-2 Delta spike gene sequence as model,our biosensor exhibits excellent analytical detection limit(50 fM)and high linearity(R2=0.987)over six orders of magnitude dynamic range from 100 fM to 10 nM without any nucleic-acid-amplification assays.The detection can be completed within 1 h with high stability and specificity which benefits from the CRISPR-Cas system.Furthermore,based on the wireless micro-electrochemical platform,the proposed biosensor reveals promising application ability in point-of-care testing. | Chenshuo Wu Zhi Chen Chaozhou Li Yabin Hao Yuxuan Tang Yuxuan Yuan Luxiao Chai Taojian Fan Jiangtian Yu Xiaopeng Ma Omar AAl-Hartomy SWageh Abdullah GAl-Sehemi Zhiguang Luo Yaqing He Jingfeng Li Zhongjian Xie Han Zhang | 2022 | Nano-Micro Letters2022，14，10： | 2 |

| 13 | Generation and characterisation of rabbit monoclonal antibodies against the native cell surface antigens of embryonic stem cells显示文摘Embryonic stem (ES) cells are potent resources for cell therapy,and monoclonal antibodies (mAbs) against native cell surface markers of ES cells could be useful tools for therapeutic applications.Here,we report the development of a feasible approach,which could be used in mass production,for experimentally producing rabbit mAbs against native cell surface antigens on the cell surface.Two of the 14 mAbs,which were selected at random,could be bound to the cell surface antigens of mES cells.The immunocytochemistry (ICC) and Western blot results showed that mAb 39 recognises conformational epitopes.The target antigen of mAb 39 was then successfully purified using an improved immunoprecipitation approach in which mAb was bounded to intact mES cells before the cells were lysed.The LC-LTQ mass spectrum analysis showed that the target antigen of mAb 39 was Glut3.This result was further confirmed by Western blot using commercially available antibodies against Glut3.Further experiments showed that mAb 39 exhibited an antiproliferative effect on mES cells.We also found that Glut3 was differentially expressed among the mES cell population as detected by flow cytometry. | Yongliang Lu Zhongyuan Su Ying Li Jingfeng Luo Zhou Tan Huijiao Ji Weimin Zhu Guoliang Yu Liangbiao Chen Ming Zhang | 2010 | Journal of Genetics and Genomics2010，37，7： | 1 |

| 16 | Insight into the Dual Cycle Mechanism of Methanol-to-OIefins Reaction over SAPO-34 Molecular Sieve by Isotopic Tracer Studies显示文摘Methanol-to-olefins(MTO)reaction is one of the important non-petroleum routes to produce light olefinsover acidic molecular sieves.In this study,the complete reaction course of MTO on SAPO-34 molecular sieve with retained organics evolution from induction period to deactivation period was investigated systematically at different weight hourly space velocities(WHSV)of methanol.By the aid of 12C/3C-methanol isotopic switch experiment,the dual cycle mechanism involving aromatics-based cycle and alkenes-based cycle was evaluated during the whole reac-tion process.The detailed reaction route varied with the evolution of the retained organics in the catalyst at different reaction stages.The aromatics-based cycle and alkenes-based cycle alternately dominate the reaction process.In the efficient reaction period,aromatics-based cvcle is the main reaction mechanism,while in the induction and deactiva-tion periods.the contribution of alkenes-based cvcle mechanism will become more important. | YU Bowen LOU Caiyi ZHANG Wenna XU Shutao HAN Jingfeng YU Zhengxi WEI Yingxu LIU Zhongmin | 2020 | Chemical Research in Chinese Universities2020，36，6： | 1 |
