| 2 | Highly Stretchable,Elastic,and Sensitive MXene-Based Hydrogel for Flexible Strain and Pressure Sensors显示文摘Electronic skin is driving the next generation of cutting-edge wearable electronic products due to its good wearability and high accuracy of information acquisition.However,it remains a challenge to fulfill the requirements on detecting full-range human activities with existing flexible strain sensors.Herein,highly stretchable,sensitive,and multifunctional flexible strain sensors based on MXene-(Ti_(3)C_(2)T_(x)-)composited poly(vinyl alcohol)/polyvinyl pyrrolidone double-network hydrogels were prepared.The uniformly distributed hydrophilic MXene nanosheets formed a three-dimensional conductive network throughout the hydrogel,endowing the flexible sensor with high sensitivity.The strong interaction between the double-network hydrogel matrix and MXene greatly improved the mechanical properties of the hydrogels.The resulting nanocomposited hydrogels featured great tensile performance(2400%),toughness,and resilience.Particularly,the as-prepared flexible pressure sensor revealed ultrahigh sensitivity(10.75 kPa^(-1))with a wide response range(0-61.5 kPa),fast response(33.5 ms),and low limit of detection(0.87 Pa).Moreover,the hydrogel-based flexible sensors,with high sensitivity and durability,could be employed to monitor fullrange human motions and assembled into some aligned devices for subtle pressure detection,providing enormous potential in facial expression and phonation recognition,handwriting verification,healthy diagnosis,and wearable electronics. | Yao Lu Xinyu Qu Wen Zhao Yanfang Ren Weili Si Wenjun Wang Qian Wang Wei Huang Xiaochen Dong | 2020 | Research2020，，1： | 14 |
| 3 | M1 muscarinic acetylcholine receptor in Alzheimer's disease显示文摘The degeneration of cholinergic neurons and cholinergic hypofunction are pathologies associated with Alzheimer's disease(AD). Muscarinic acetylcholine receptors(mAChRs) mediate acetylcholine-induced neurotransmission and five mAChR subtypes(M1–M5) have been identified. Among them, M1 mAChR is widely expressed in the central nervous system and has been implicated in many physiological and pathological brain functions. In addition, M1 mAChR is postulated to be an important therapeutic target for AD and several other neurodegenerative diseases. In this article, we review recent progress in understanding the functional involvement of M1 mAChR in AD pathology and in developing M1 mAChR agonists for AD treatment. | Shangtong Jiang Yanfang Li Cuilin Zhang Yingjun Zhao Guojun Bu Huaxi Xu Yun-Wu Zhang | 2014 | Neuroscience Bulletin2014，30，2： | 10 |
| 4 | One-step base editing in multiple genes by direct embryo injection for pig trait improvement显示文摘The precise and simultaneous acquisition of multiple beneficial alleles in the genome is in great demand for the development of elite pig breeders. Cytidine base editors(CBEs) that convert C:G to T:A have emerged as powerful tools for single-nucleotide replacement. Whether CBEs can effectively mediate C-to-T substitution at multiple sites/loci for trait improvement by direct zygote injection has not been verified in large animals. Here, we determined the editing efficiency of four CBE variants in porcine embryonic fibroblast cells and embryos. The findings showed that hA3A-BE3-Y130F and hA3A-eBE-Y130F consistently resulted in increased base-editing efficiency and low toxic effects in embryonic development. Further, we verified that using a one-step approach, direct zygote microinjection of the CBE system can generate pigs harboring multiple point mutations.Our process resulted in a stop codon in CD163 and myostatin(MSTN) and introduced a beneficial allele in insulin-like growth factor-2(IGF2). The pigs showed disrupted expression of CD163 and MSTN and increased expression of IGF2, which significantly improved growth performance and infectious disease resistance. Our approach allows immediate introduction of multiple mutations in transgene-free animals to comprehensively improve economic traits through direct embryo microinjection,providing a potential new route to produce elite pig breeders. | Ruigao Song Yu Wang Qiantao Zheng Jing Yao Chunwei Cao Yanfang Wang Jianguo Zhao | 2022 | Science China(Life Sciences)2022，65，4： | 9 |

| 6 | Maize grain concentrations and above-ground shoot acquisition of micronutrients as affected by intercropping with turnip, faba bean, chickpea, and soybean显示文摘Most research on micronutrients in maize has focused on maize grown as a monocrop. The aim of this study was to determine the effects of intercropping on the concentrations of micronutrients in maize grain and their acquisition via the shoot. We conducted field experiments to investigate the effects of intercropping with turnip (Brassica campestris L.), faba bean (Vicia faba L.), chickpea (Cicer arietinum L.), and soybean (Glycine max L.) on the iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn) concentrations in the grain and their acquisition via the above-ground shoots of maize (Zea mays L.). Compared with monocropped maize grain, the grain of maize intercropped with legumes showed lower concentrations of Fe, Mn, Cu, and Zn and lower values of their corresponding harvest indexes. The micronutrient concentrations and harvest indexes in grain of maize intercropped with turnip were the same as those in monocropped maize grain. Intercropping stimulated the above-ground maize shoot acquisition of Fe, Mn, Cu and Zn, when averaged over different phosphorus (P) application rates. To our knowledge, this is the first report on the effects of intercropping on micronutrient concentrations in maize grain and on micronutrients acquisition via maize shoots (straw+grain). The maize grain Fe and Cu concentrations, but not Mn and Zn concentrations, were negatively correlated with maize grain yields. The concentrations of Fe, Mn, Cu, and Zn in maize grain were positively correlated with their corresponding harvest indexes. The decreased Fe, Mn, Cu, and Zn concentrations in grain of maize intercropped with legumes were attributed to reduced translocation of Fe, Mn, Cu, and Zn from vegetative tissues to grains. This may also be related to the delayed senescence of maize plants intercropped with legumes. We conclude that turnip/maize intercropping is beneficial to obtain high maize grain yield without decreased concentrations of Fe, Mn, Cu, and Zn in the grain. Further research is required to clarify the mechanisms underlying the changes in micronutrient concentrations in grain of intercropped maize. | XIA HaiYong ZHAO JianHua SUN JianHao XUE YanFang EAGLING Tristan BAO XingGuo ZHANG FuSuo LI Long | 2013 | Science China(Life Sciences)2013，56，9： | 8 |
| 7 | Development of a new method for analyzing free aluminum ions(Al^(3+)) in seafood using HPLC-ICP-MS显示文摘This paper presents a novel method for simultaneous online examination of free aluminum ions(Al3+)in seafood,using solidphase extraction and high-performance liquid chromatography online with inductively coupled plasma mass spectrometry(SPEHPLC-ICP-MS),without post-column reaction.The optimum conditions for chromatographic separation of Al3+were achieved using an IonPac CS5A analytical column with an IonPac CG5A guard column.The mobile phase consisted of 0.040 mol/L LiOH,0.0060 mol/L 2,6-pyridinedicarboxylic acid,and 0.090 mol/L CH3COOH(pH 4.7).The free Al3+ions in seafood were extracted by shaking with the mobile phase at 70°C for 2 h.SPE was conducted using an Oasis MCX,3cc/60 mg,30μm column,which was activated and equilibrated with 2 mL of methanol and 4 mL of deionized water before use.HCl(0.075 mol/L,2 mL)was used to wash inorganic Al from the SPE column.The standard recoveries of Al3+were all above 89%and the relative standard deviations were all below 5%.The proposed method was successfully used for the examination of Al3+in seafood samples,and the results were similar to those obtained using the static equilibrium method. | SHANG DeRong ZHAO YanFang ZHAI YuXiu NING JinSong DING HaiYan SHENG XiaoFeng | 2013 | Chinese Science Bulletin2013，58，35： | 8 |
| 8 | Economic Value Evaluation of Wetland Service in Yeyahu Wetland Nature Reserve,Beijing显示文摘Based on multi-source data,this paper evaluated the economic value of ecological services in the Yeyahu Wetland Nature Reserve,Beijing,China.The ecological services of wetland included gas regulation,water quality im-provement,biodiversity maintenance,erosion control,water supply,recreational opportunity,raw material supply and existence value.Multiple conventional evaluation methods were used to calculate the value of eight wetland services.The results showed that significant values came from biodiversity maintenance and recreational opportunity.The main reasons were as follows.Firstly,Yeyahu Wetland Nature Reserve was the habitat for migrant birds,and government had payed more efforts to protect precious birds.Secondly,the population is large in Beijing.People enjoyed going outside and enjoyed the natural and artificial wetland scenes.At the same time,most people were prepared to pay for wetland conservation.The decline of vegetation cover made the economic value of erosion control the lowest.While the shrink of water resource and the deteriorative water quality caused the economic value of water supply lower.The evaluation results could help decision-makers understand the present status of the Yeyahu Wetland Nature Reserve and provide a scientific basis for strategic decision. | ZHU Lin CHEN Yun GONG Huili JIANG Weiguo ZHAO Wenji XIAO Yanfang | 2011 | Chinese Geographical Science2011，21，6： | 7 |

| 10 | Recent advances in research on vine tea,a potential and functional herbal tea with dihydromyricetin and myricetin as major bioactive compounds显示文摘Vine tea has been used as an herbal tea by several ethnic minorities for hundreds of years in China.Flavonoids,a kind of indispensable component in a variety of nutraceutical,pharmaceutical and cosmetic applications,are identified to be the major metabolites and bioactive ingredients in vine tea.Interestingly,vine tea exhibits a wide range of significant bioactivities including anti-oxidant,anti-inflammatory,anti-tumor,antidiabetic,neuroprotective and other activities,but no toxicity.These bioactivities,to some extent,enrich the understanding about the role of vine tea in disease prevention and therapy.The health benefits of vine tea,particularly dihydromyricetin and myricetin,are widely investigated.However,there is currently no comprehensive review available on vine tea.Therefore,this report summarizes the most recent studies investigating bioactive constituents,pharmacological effects and possible mechanisms of vine tea,which will provide a better understanding about the health benefits and preclinical assessment of novel application of vine tea. | Qili Zhang Yanfang Zhao Meiyan Zhang Yalu Zhang Hongfang Ji Liang Shen | 2021 | Journal of Pharmaceutical Analysis2021，11，5： | 7 |
| 11 | Feasibility of Tea Saponin-Enhanced Soil Washing in a Soybean Oil-Water Solvent System to Extract PAHs/Cd/Ni Efficiently from a Coking Plant Site显示文摘Mixed contaminated brownfield sites have brought serious risks to human health and environmental safety. With the purpose of removing polycyclic aromatic hydrocarbons(PAHs) and heavy metals from a coking plant site, an innovative technology for ex-situ washing was developed in the present work. The combination of 15.0 mL L^(-1) soybean oil and 7.5 g L^(-1) tea saponin proved an effective method to extract co-pollutants from soil. After two consecutive washing cycles, the efficiency rates of removal for 3-, 4-,5(+6)-ring, and total PAHs, Cd, and Ni were approximately 98.2%, 96.4%, 92.3%, 96.3%, 94.1%, and 89.4%, respectively. Meanwhile,as evaluated by Tenax extraction method and metal stability indices, the residual PAHs and heavy metals after consecutive washing mainly existed in the form with extremely low bioaccessibility in the soil. Thus, in the soil after two washing cycles, there appeared limited environmental transfer risk of co-pollutants. Moreover, a subsequent precipitation method with alkaline solution and PAHdegrading strain Sphingobium sp. PHE9 inoculation effectively removed 84.6%–100% of Cd, 82.5%–91.7% of Ni, and 92.6%–98.4% of PAHs from the first and second washing solvents. The recovered solvents also exhibited a high recycling effectiveness. Therefore, the combined cleanup strategy proposed in this study proved environmentally friendly, which also played a major role in risk assessment and management in mixed polluted sites. | YE Mao SUN Mingming XIE Shanni LIU Kuan FENG Yanfang ZHAO Yu WAN Jinzhong HU Feng LI Huixin ZONG Lianggang JIANG Xin | 2017 | Pedosphere2017，27，3： | 5 |
| 12 | Pyridine-induced interfacial structural transformation of tetraphenylethylene derivatives investigated by scanning tunneling microscopy显示文摘The two-dimensional self-assembly behaviors of tetraphenylethylene (TPE)molecules are significant for further applications, but reports are rare. The self-assembled structures of two C2-symmetry TPE derivatives (H4TCPE and H4ETrC)possessing propeller structures and their stimulus responses to the additionof vinylpyridine derivatives were thoroughly studied with the assistance ofscanning tunneling microscopy (STM) technique in combination with densityfunctional theory (DFT) calculations. Although their chemical structures weresimilar, the H4TCPE and H4ETTC molecules self-assembled into closely packedlamellar and quadrilateral structures, respectivel3~ at the 1-heptanoic acid/HOPGinterface. After the addition of pyridine derivatives (DPE, PEBP-C4, andPEBP-C8), H4TCPE and H4ETTC showed different responsiveness resultingin different co-assembly structures. The results indicated that the structuresof pyridine derivatives--including backbones and substituents--affected theintermolecular interactions of both H4TCPE/pyridine and H4ETTC/pyridinesystems. The modification of the self-assembly behaviors of propeller-shapedI-hTCPE and H4ETTC would contribute to the construction of more complexmultilevel nanostructures. | Xuan Peng Linxiu Cheng Xiaoyang Zhu Yanfang Geng Fengying Zhao Kandong Hu Xuan Guo Ke Deng Qingdao Zeng | 2018 | Nano Research2018，11，11： | 4 |
| 13 | Base editing in pigs for precision breeding显示文摘Pigs are one of the most important domesticated animals and have great value in agriculture and biomedicine.Single nucleotide polymorphisms(SNPs)are a dominant type of genetic variation among individual pigs and contribute to the formation of traits.Precision single base substitution provides a strategy for accurate genetic improvement in pig production with the characterization of functional SNPs and genetic variants in pigs.Base editing has recently been developed as the latest gene-editing tool that can directly make changes in single nucleotides without introducing double-stranded DNA breaks(DSBs),providing a promising solution for precise genetic modification in large animals.This review summarizes gene-editing developments and highlights recent genetic dissection related to SNPs in major economic traits which may have the potential to be modified using SNP-editing applications.In addition,limitations and future directions of base editing in pig breeding are discussed. | Ruigao SONG Yu WANG Yanfang WANG Jianguo ZHAO | 2020 | Frontiers of Agricultural Science and Engineering2020，7，2： | 4 |
| 14 | Thermoresponsive Lignin-Reinforced Poly(Ionic Liquid)Hydrogel Wireless Strain Sensor显示文摘To meet critical requirements on flexible electronic devices,multifunctionalized flexible sensors with excellent electromechanical performance and temperature perception are required.Herein,lignin-reinforced thermoresponsive poly(ionic liquid)hydrogel is prepared through an ultrasound-assisted synthesized method.Benefitting from the electrostatic interaction between lignin and ionic liquid,the hydrogel displays high stretchability(over 1425%),excellent toughness(over 132 kPa),and impressive stress loading-unloading cyclic stability.The hydrogel strain sensor presents excellent electromechanical performance with a high gauge factor(1.37)and rapid response rate(198 ms),which lays the foundation for human body movement detection and smart input.Moreover,owing to the thermal-sensitive feature of poly(ionic liquid),the as-prepared hydrogel displays remarkable thermal response sensitivity(0.217℃^(-1))in body temperature range and low limit of detection,which can be applied as a body shell temperature indicator.Particularly,the hydrogel can detect dual stimuli of strain and temperature and identify each signal individually,showing the specific application in human-machine interaction and artificial intelligence.By integrating the hydrogel strain sensor into a wireless sensation system,remote motion capture and gesture identification is realized in real-time. | Xinyu Qu Ye Zhao Zi’ang Chen Siying Wang Yanfang Ren Qian Wang Jinjun Shao Wenjun Wang Xiaochen Dong | 2021 | Research2021，，1： | 3 |
| 15 | MXene-composited highly stretchable,sensitive and durable hydrogel for flexible strain sensors显示文摘The flourishing development in flexible electronics has provoked intensive research in flexible strain sensors to realize accurate perception acquisition under different external stimuli.However,building hydrogel-based strain sensors with high stretchability and sensitivity remains a great challenge.Herein,MXene nanosheets were composited into polyacrylamide-sodium alginate matrix to construct mechanical robust and sensitive double networked hydrogel strain sensor.The hydrophilic MXene nanosheets formed strong interactions with the polymer matrix and endowed the hydrogel with excellent tensile properties(3150%),compliant mechanical strength(2.03 kPa^(-1)in Young’s Module)and long-lasting stability and fatigue resistance(1000 dynamic cycles under 1,600%strain).Due to the highly oriented MXene-based three dimensional conductive networks,the hydrogel sensor achieved extremely high tensile sensitivity(18.15 in gauge factor)and compression sensitivity(0.38 kPa^(-1)below 3 kPa).MXene hydrogel-based strain sensors also displayed negligible hysteresis in electromechanical performance,typical frequent-independent feature and rapid response time to external stimuli.Moreover,the sensor exhibited accurate response to different scales of human movements,providing potential application in speech recognition,expression recognition and handwriting verification. | Wei Yuan Xinyu Qu Yao Lu Wen Zhao Yanfang Ren Qian Wang Wenjun Wang Xiaochen Dong | 2021 | Chinese Chemical Letters2021，32，6： | 3 |
| 16 | Structural Characterization of Glucan Produced by Lactobacillus sake L-7 from Sausage显示文摘A linear glucan was produced by Lactobacillus sake L-7 isolated from homemade sausage. Cultivation of the strain in Man–Rogosa–Sharpe(MRS) medium containing 50 g/L sucrose yielded 5.3 g/L of purified exopolysaccharide(EPS). The EPS was characterized by gas chromatography(GC), Fourier-transform infrared(FT-IR) spectroscopy, high-performance sizeexclusion chromatography(HPSEC), nuclear magnetic resonance(NMR) spectroscopy, and scanning electron microscopy(SEM). The monosaccharide composition of the EPS was glucose, and its molecular weight was 1 × 10~7 Da. The FT-IR and NMR spectra revealed that the L-7 EPS was a linear glucan with α-(1 → 6) glucosidic bonds. SEM images of the dried EPS revealed a hollow tubular structure. The water solubility index and water holding capacity of L-7 EPS were 96 and 272%, respectively. The results of hydrolysis indicated that L-7 EPS was not susceptible to hydrolysis by physiological barriers and can be used as a soluble dietary fiber with health benefits. All these characteristics suggest that L-7 EPS might have potential applications in the food, cosmetic, and pharmaceutical industries. | Fang Feng Qingqing Zhou Yanfang Yang Fangkun Zhao Renpeng Du Ye Han Zhijiang Zhou | 2019 | Transactions of Tianjin University2019，25，1： | 3 |
| 17 | Ultradurable,freeze-resistant,and healable MXene-based ionic gels for multi-functional electronic skin显示文摘Hydrogel is a potential matrix material of electronic-skins(E-skins)because of its excellent ductility,tunability,and biocompatibility.However,hydrogel-based E-Skins will inevitably lose their sensing performance in practical applications for water loss,physical damage,and ambient interferences.It remains a challenge to manufacture highly durable gel-based E-skins.Herein,an E-Skin is fabricated by introducing ionic liquids(ILs)into MXene-composited binary polymer network.The obtained ionic gel shows excellent mechanical properties,strong adhesion,and superior tolerance to harsh environments.The E-skin exhibits high sensitivity to both strain and pressure in a wide range of deformations,which enables a monitoring function for various human motions and physiological activities.Importantly,the E-skin shows consistent electrical response after being stored in the open air for 30 days and can be quickly healed by irradiation with 808 nm near-infrared light,originating from the photo-thermal effect induced self-healing acceleration.It is noteworthy that the E-skin also reveals a highly sensitive perception of temperature and near-infrared light,displaying the promising potential applications in the multifunctional flexible sensor. | Yao Lu Xinyu Qu Siying Wang Ye Zhao Yanfang Ren Wenli Zhao Qian Wang Chencheng Sun Wenjun Wang Xiaochen Dong | 2022 | Nano Research2022，15，5： | 2 |
| 18 | Performance Analysis of Intelligent CR-NOMA Model for Industrial IoT Communications显示文摘Aiming for ultra-reliable low-latency wireless communications required in industrial internet of things(IIoT)applications,this paper studies a simple cognitive radio non-orthogonal multiple access(CR-NOMA)downlink system.This system consists of two secondary users(SUs)dynamically interfered by the primary user(PU),and its performance is characterized by the outage probability of the SU communications.This outage probability is calculated under two conditions where,a)the transmission of PU starts after the channel state information(CSI)is acquired,so the base station(BS)is oblivious of the interference,and b)when the BS is aware of the PU interference,and the NOMA transmission is adapted to the more comprehensive knowledge of the signal to interference plus noise ratio(SINR).These results are verified by simulations,and their good agreement suggests our calculations can be used to reduce the complexity of future analysis.We find the outage probability is reduced when the SUs move further away from the primary transmitter or when the signal from PU is less powerful,and the BS always has better performance when it is aware of the interference.The findings thus emphasize the importance of monitoring the channel quality and realtime feedback to optimize the performance of CR-NOMA system. | Yinghua Zhang Jian Liu Yunfeng Peng Yanfang Dong Changming Zhao | 2020 | Computer Modeling in Engineering & Sciences2020，，10： | 2 |
| 19 | Sensitivity analysis of CO_2 sequestration in saline aquifers显示文摘Carbon capture and storage (CCS) technology has been considered as an important method for reducing greenhouse gas emissions and for mitigating global climate change. Three primary options are being considered for large-scale storage of CO 2 in subsurface formations: oil and gas reservoirs, deep saline aquifers, and coal beds. There are very many large saline aquifers around the world, which could make a big contribution to mitigating global warming. However, we have much less understanding of saline aquifers than oil and gas reservoirs. Several mechanisms are involved in the storage of CO 2 in deep saline aquifers, but the ultimate goal of injection of CO 2 into the aquifers containing salt water is to dissolve the CO 2 in the water. So it is important to study the solubility trapping and sensitivity factors of CO 2 in saline aquifers. This paper presents results of modeling CO 2 storage in a saline aquifer using the commercial reservoir simulator ECLIPSE. The objective of this study was to better understand the CO 2 /brine phase behavior (PVT properties) and quantitatively estimate the most important CO 2 storage mechanism in brine-solubility trapping. This would provide a tool by performing theoretical and numerical studies that help to understand the feasibility of CO 2 geological storage. A 3-dimensional, 2-phase (water/gas) conceptional reservoir model used finite, homogenous and isothermal formations into which CO 2 is injected at a constant rate. The effects of main parameters were studied, including the vertical to horizontal permeability ratio k v /k h , salinity, and residual phase saturations. The results show that the vertical to horizontal permeability ratio has a significant effect on CO 2 storage. Moreover, more CO 2 dissolves in the brine at lower k v /k h values. | Zhao Hongjun Liao Xinwei Chen Yanfang Zhao Xiaoliang | 2010 | Petroleum Science2010，7，3： | 2 |
| 20 | Isolation, Purification, and Characterization of Exopolysaccharide Produced by Leuconostoc Citreum N21 from Dried Milk Cake显示文摘A strain with high production of exopolysaccharide(EPS) was isolated from dried milk cake(a traditional fermented food from Inner Mongolia). The strain was called N21 and later identified as Leuconostoc citreum( Leu. citreum). The strain was cultured in Man-Rogosa-Sharpe medium containing 50 g/L of sucrose for 48 h at 30 °C and the EPS purified, with a yield of 24.5 g/L. An average molecular weight of 6.07 × 10~6 g/mol was determined by high-performance size-exclusion chromatography. The structure of the purified EPS was investigated through gas chromatography, ~1H and ^(13)C nuclear magnetic resonance spectroscopy, and Fourier transform infrared spectroscopy. The results demonstrated a polysaccharide composed of D-glucopyranose units in a linear chain with consecutive α(1 → 6) linkages. No branching was found in the structure of the exopolysaccharide. The purified EPS showed high water solubility and emulsibility. Based on the thermogravimetric curve, the degradation temperature of the EPS was 308.47 °C, which suggested that the dextran in the study exhibited high thermal stability. The results indicated that Leu. citreum N21 could be widely used to produce linear EPS and that the EPS has potential applications in food science and processing as a food additive. | Yanfang Yang Fang Feng Qingqing Zhou Fangkun Zhao Renpeng Du Zhijiang Zhou Ye Han | 2019 | Transactions of Tianjin University2019，25，2： | 2 |
