| 1 | 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 |
| 2 | Water regime-nitrogen fertilizer incorporation interaction:Field study on methane and nitrous oxide emissions from a rice agroecosystem in Harbin, China显示文摘Water regime and nitrogen(N) fertilizer are two important factors impacting greenhouse gases(GHG) emission from paddy field, whereas their effects have not been well studied in cold region. In this study, we conducted a two-year field experiment to study the impacts of water regime and N fertilizer on rice yields and GHG emissions in Harbin, China, a cold region located in high latitudes. Our results showed that intermittent irrigation significantly decreased methane(CH_4) emission compared with continuous flooding, however,the decrement was far lower than the global average level. The N_2O emissions were very small when flooded but peaked at the beginning of the disappearance of floodwater. The N fertilizer treatments increased CH_4 emissions at low level(75 kg N/ha). But both CH_4 and N_2O emissions were uninfluenced at the levels of 150 kg N/ha and 225 kg N/ha. Rice yields increased under intermittent irrigation and were highest at the level of 150 kg N/ha. From our results, we recommended that the intermittent irrigation and 150 kg N/ha as the ideal water regime-nitrogen fertilizer incorporation for this area to achieve low GHG emissions without impacting rice yields. | Wenjun Dong Jia Guo Lijun Xu Zhifeng Song Jun Zhang Ao Tang Xijuan Zhang Chunxu Leng Youhong Liu Lianmin Wang Lizhi Wang Yang Yu Zhongliang Yang Yilei Yu Ying Meng Yongcai Lai | 2018 | Journal of Environmental Sciences2018，30，2： | 12 |
| 3 | Recent Advances in Tumor Microenvironment Hydrogen Peroxide-Responsive Materials for Cancer Photodynamic Therapy显示文摘Photodynamic therapy(PDT),as one of the noninvasive clinical cancer phototherapies,suffers from the key drawback associated with hypoxia at the tumor microenvironment(TME),which plays an important role in protecting tumor cells from damage caused by common treatments.High concentration of hydrogen peroxide(H2O2),one of the hallmarks of TME,has been recognized as a double-edged sword,posing both challenges,and opportunities for cancer therapy.The promising perspectives,strategies,and approaches for enhanced tumor therapies,including PDT,have been developed based on the fast advances in H2O2-enabled theranostic nanomedicine.In this review,we outline the latest advances in H2O2-responsive materials,including organic and inorganic materials for enhanced PDT.Finally,the challenges and opportunities for further research on H2O2-responsive anticancer agents are envisioned. | Nan Yang Wanyue Xiao Xuejiao Song Wenjun Wang Xiaochen Dong | 2020 | Nano-Micro Letters2020，12，1： | 11 |
| 4 | Two-dimensional metal-organic-framework as a unique theranostic nano-platform for nuclear imaging and chemo-photodynamic cancer therapy显示文摘Nanoscale metal organic frameworks (NMOFs) with porous structure and inherent biodegradability are attractive nanomedicine platforms.In addition to conventional particulate NMOFs,two-dimensional (2D) NMOFs are emerging as a unique type of NMOFs which however have been relatively less explored for nanomedicine applications.Herein,2D NMOFs composed of Zn2+ and tetrakis(4-carboxyphenyl) porphyrin (TCPP) are fabricated and functionalized with polyethylene glycol (PEG).Compared to their particulate counterpart,such 2D NMOFs show greatly increased drug loading capacity and enhanced light-triggered singlet oxygen production,promising for chemotherapy and photodynamic therapy (PDT),respectively.Utilizing the porphyrin structure of TCPP,our 2D NMOFs could be labeled with a diagnostic radioisotope,99mTc,for single photon emission computer tomography (SPECT) imaging,which reveals efficient tumor homing of those 2D NMOFs upon intravenous injection.While offering a remarkable synergistic in vivo antitumor effect for the combined chemo-PDT,such 2D NMOFs show efficient biodegradation and rapid renal clearance.Our work presents the great promise of 2D NMOFs for nanomedicine applications. | Wenjun Zhu Yu Yang Qiutong Jin Yu Chao Longlong Tian Jingjing Liu Ziliang Dong Zhuang Liu | 2019 | Nano Research2019，12，6： | 9 |
| 5 | New Re-Os Isotopic Constrains on the Formation of the Metalliferous Deposits of the Lower Cambrian Niutitang Formation显示文摘The Terreneuvian Epoch(541–521 Ma)is also an important period for metallogenesis in South China, as was represented by the widespread occurrences of Ni-Mo polymetallic layers on the antecedent shallow platform margin and the V-enriched black shales in deeper slope-basin settings. In this study, we have measured Re-Os isochron ages of Ni-Mo polymetallic layers(Songlin, Niuchang, Sancha, Chuanpengwan), V-rich black shales(Bahuang), and non-metalliferous black shales(Shuidong) in the basal Niutitang Formation in Guizhou and Hunan province, South China. The Ni-Mo polymetallic layers and V-enriched black shales have similar Re-Os isochron ages, suggesting concurrent deposition of these two types of metalliferous ores. This suggestion is consistent with the traditional stratigraphic correlation by using the nodular phosphorite bed directly underlying these metalliferous layers as a stratigraphic marker. Furthermore, the metalliferous ores and non-metalliferous black shales have similar initial ^(187)Os/^(188) Os ratios of 0.8–0.9, arguing for a dominant seawater origin with minor contribution of hydrothermal activity. Furthermore, Re-Os isotopic data also imply that Ni-Mo and V ore might have derived from the same source. We suggest that the spatial distribution of metalliferous ores can be explained by the development of non-sulfidic anoxic-suboxic wedge(NSASW) in the slope-basin and sulfidic wedge in the previous platform margin. Upwelling of deep water first transects the mildly reduced, organic rich NSASW, in which V(V) is reduced to V(IV), and is preferentially removed from seawater by organometallic complex formation. As a result, V-rich black shale deposits in the slope-basin of Yangtze Platform. Further movement of deep water into the sulfidic platform margin results in Ni-Mo polymetallic layer formation. | Yong Fu Lin Dong Chao Li Wenjun Qu Haoxiang Pei Wenlang Qiao Bing Shen | 2016 | Journal of Earth Science2016，27，2： | 9 |
| 6 | Overexpression of lysine specific demethylase 1 predicts worse prognosis in primary hepatocellular carcinoma patients显示文摘AIM:To investigate the clinicopathological features and prognostic value of lysine specific demethylase 1(LSD1) in hepatocellular carcinoma(HCC).METHODS:We examined LSD1 expression in 60 paired liver cancer tissues and adjacent noncancerous tissues by quantitative real time polymerase chain reaction(qRT-PCR) and Western blotting.In addition,we analyzed LSD1 expression in 198 HCC samples by immunohistochemistry.The relationship between LSD1 expression,clinicopathological features and patient survival was investigated.RESULTS:Immunohistochemistry,Western blotting,and qRT-PCR consistently confirmed LSD1 overexpression in HCC tissues compared to adjacent non-neoplastic tissues(P < 0.01).Additionally,immunostaining showed more LSD1-positive cells in the higher tumor stage(T3-4) and tumor grade(G3) than in the lower tumor stage(T1-2,P < 0.001) and tumor grade(G1-2,P < 0.001),respectively.Moreover,HCC patients with high LSD1 expression had significantly lower 5-year overall survival rates(P < 0.001) and lower 5-year disease-free survival rates(P < 0.001),respectively.A Cox proportional hazards model further demonstrated that LSD1 over-expression was an independent predictor of poor prognosis for both 5-year disease-free survival [hazards ratio(HR) = 1.426,95%CI:0.672-2.146,P < 0.001] and 5-year overall survival(HR = 2.456,95%CI:1.234-3.932,P < 0.001) in HCC.CONCLUSION:Our data suggest for the first time that the overexpression of LSD1 protein in HCC tissues indicates tumor progression and predicts poor prognosis. | Ze-Kun Zhao Hai-Feng Yu Dao-Rong Wang Ping Dong Lei Chen Wen-Guang Wu WenJun Ding Ying-Bin Liu | 2012 | World Journal of Gastroenterology2012，18，45： | 8 |
| 7 | Lingguizhugan Decoction, a Chinese herbal formula, improves insulin resistance in overweight/obese subjects with non-alcoholic fatty liver disease: a translational approach显示文摘Lingguizhugan Decoction(LGZG)has been investigated in basic studies,with satisfactory effects on insulin resistance in non-alcoholic fatty liver disease(NAFLD).This translational approach aimed to explore the effect and underlying mechanism of LGZG in clinical setting.A randomized,double-blinded,placebo-controlled trial was performed.A total of 243 eligible participants with NAFLD were equally allocated to receive LGZG(two groups:standard dose and low dose)or placebo for 12 weeks on the basis of lifestyle modifications.The primary efficacy variable was homeostasis model assessment of insulin resistance(HOMA-IR).Analyses were performed in two populations in accordance with body mass index(BMI;overweight/obese,BMI 24 kg/m^(2);lean,BMI<24 kg/m^(2)).For overweight/obese participants,low-dose LGZG significantly decreased their HOMA-IR level compared with placebo(0.19(1.47)versus 0.08(1.99),P=0.038).For lean subjects,neither dose of LGZG showed a superior effect compared with placebo.Methylated DNA immunoprecipitation sequencing and real-time qPCR found that the DNA N6-methyladenine modification levels of protein phosphatase 1 regulatory subunit 3A(PPP1R3A)and autophagy related 3(ATG3)significantly increased after LGZG intervention in overweight/obese population.Low-dose LGZG effectively improved insulin resistance in overweight/obese subjects with NAFLD.The underlying mechanism may be related to the regulation of DNA N6-methyladenine modification of PPP1R3A and ATG3.Lean subjects may not be a targeted population for LGZG. | Liang Dai Jingjuan Xu Baocheng Liu Yanqi Dang Ruirui Wang Lijie Zhuang Dong Li Lulu Jiao Jianying Wang Lei Zhang Linda LDZhong Wenjun Zhou Guang Ji | 2022 | Frontiers of Medicine2022，16，5： | 7 |
| 8 | Drainage Responses to the Activity of the Langshan Range-Front Fault and Tectonic Implications显示文摘Langshan, a monoclinic mountain, which started to uplift since Oligocene, bounds the northwest margin of the Hetao Basin. The continuous activity of the active normal Langshan rangefront fault forms the typical basin-and-range landform in Langshan area and controls the landform evolution of Langshan. Langshan is an ideal place to study relationship between quantitative geomorphological index and active deformation. According to study on knickpoints, fitting on longitudinal channel profiles and steepness index, we demonstrate that the main controlling factors on distribution of normalized steepness index of channels are not climate(precipitation), lithology, sediment flux, but tectonic factor, or the activity of Langshan range-front fault. The short channels in southeast flank, whose lengths are shorter than 16 km, may be still in the non-steady status. If not considering these short channels, the distribution of normalized steepness index along the Langshan range-front fault appears like M-shape pattern, while the normalized steepness index in the middle section is higher than those at both ends. This pattern is well consistent with geometrical segmentation model of the Langshan range-front fault. Combining previous active tectonic research on Langshan range-front fault, which demonstrates the Langshan range-front fault has been in the stage of linkup, we reasonably infer the Langshan range-front fault now is the result of linkup of both fault which continuously bilaterally extended independently. Our tectonic geomorphological study also supports the conclusion that the Langshan range-front fault has been in the stage of linkup. The formation of several knickpoints due to tectonic factor may have been caused by slip-rate variation because of linkup of both independent faults. Based on cognition above, we also proposed the geological and geomorphological evolutionary model of the Langshan range-front fault since Oligocene. | Shaopeng Dong Peizhen Zhang Huiping Zhang Wenjun Zheng Huixian Chen | 2018 | Journal of Earth Science2018，29，1： | 6 |

| 10 | Impacts of nighttime post-anthesis warming on rice productivity and grain quality in East China显示文摘The impacts of nighttime post-anthesis warming on rice productivity and grain quality in East China were evaluated for two cultivars, II You 128, an indica rice, and Wuyunjing 7, a japonica rice. Warming by 3.0 °C stimulated the nighttime respiration rate and decreased the photosynthesis rate, resulting in significant decreases of 21.2% and 24.9% in aboveground biomass accumulation for II You 128 and Wuyunjing 7, respectively. Warming significantly reduced the rates of seed setting and grain filling, especially of inferior kernels(those lower in panicles), while the filling rate of superior kernels remained almost unchanged. As a result, 1000-grain weight and grain yield were respectively 3.7% and 30.0% lower for II You 128 and 12.8% and 34.3% for Wuyunjing 7 in warmed plots than in the unwarmed control. Nighttime warming also significantly reduced the grain milling and appearance quality of both varieties. More negative effects of warming on inferior than on superior kernels were found. The above results have important implications for rice variety cultivation in East China. | Wenjun Dong Jin Chen Lili Wang Yunlu Tian Bin Zhang Yongcai Lai Ying Meng Chunrong Qian Jia Guo | 2014 | The Crop Journal2014，2，1： | 6 |
| 11 | Chemoselective hydrogenolysis of tetrahydrofurfuryl alcohol to 1,5-pentanediol over Ir-MoO_x/SiO_2 catalyst显示文摘In this work, MoOx promoted Ir/SiO2 catalysts were prepared and used for the selective hydrogenolysis of tetrahydrofurfuryl alcohol(THFA)to 1,5-pentanediol in a continuous flow reactor. The effects of different noble metals(Ir, Pt, Pd, Ru, Rh), supports and Ir contents were screened.Among the investigated catalysts, 4 wt%Ir-MoOx/SiO2 with a Mo/Ir atomic ratio of 0.13 exhibited the best catalytic performance. The synergy between Ir particles and the partially reduced isolated MoOx species attached on them is essential for the excellent catalytic performance of Ir-MoOx/SiO2. The catalyst exhibited a better hydrogenolysis efficiency of THFA with the selectivity of 1,5-pentanediol of 65%–74% at a conversion of THFA of 70%–75% when the initial THFA concentration is ranging from 20 wt% and 40 wt%. And higher system pressure was also in favor of the conversion of THFA. During a stability test, the conversion of THFA and 1,5-pentanediol yield over Ir-MoOx/SiO2 decreased with reaction time, which can be explained by the leaching of Mo species during the reaction. | Zhiqiang Wang Boonrat Pholjaroen Mengxia Li Wenjun Dong Ning Li Aiqin Wang Xiaodong Wang Yu Cong Tao Zhang | 2014 | Journal of Energy Chemistry2014，23，4： | 6 |
| 12 | Microstructure and mechanical behavior of the Mg-Mn-Ce magnesium alloy sheets显示文摘The microstructural evolution and mechanical behavior of Mg-Mn-Ce magnesium alloy were investigated in the present study.Mg alloy was prepared with metal model casting method and subsequently hot extruded at 703 K with the reduction ratio of 101:1.The grains were dynamically recrystallized after the extrusion process.Moreover,the(0002)pole figure of Mg-Mn-Ce alloy developed a splitting of pronounced basal texture.The mechanical properties were different due to different angles between c-axis and loading direction(0°,45°and 90°)in the tensile tests.This significantly induces an asymmetry in the yield behavior.The Mg-Mn-Ce alloy exhibits a classical dimple structure as a result of slip accumulation and ductile tear. | Qingshan Yang Bin Jiang Xin Li Hanwu Dong Wenjun Liu Fusheng Pan | 2014 | Journal of Magnesium and Alloys2014，2，1： | 6 |
| 13 | Polyimide-derived carbon nanofiber membranes as anodes for high-performance flexible lithium ion batteries显示文摘The strategy of N-doping in carbon materials could provide additional Li-ion storage sites to improve their electrochemical properties. Heteroatom-containing polymers could serve as good precursors to fabricate doped carbons due to the capability to in situ dope heteroatoms into the structures. In this work,electrospun heterocyclic polyimide(PI) nanofiber membranes containing biphenyl and pyrimidine rings were carbonized to fabricate freestanding and flexible heteroatoms-containing carbon membranes.When the polymer membranes were subjected to various calcination temperatures(from 550℃ to950℃) and durations(0.5-10 h), the structural evolutions strongly affect their electrochemical properties as anodes for lithium ion batteries. It demonstrated that the reversible specific capacity of obtained sample treated at 650℃ for 3 h could achieve 695 mAh/g at 0.1 A/g and retain 245 mAh/g at 1.5 A/g after300 cycles. Furthermore, the electrospun membrane maintains a good electrochemical performance at bending state as a flexible electrode. | Fangyuan Zhao Xin Zhao Bo Peng Feng Gan Mengyao Yao Wenjun Tan Jie Dong Qinghua Zhang | 2018 | Chinese Chemical Letters2018，29，11： | 5 |
| 14 | Safety and effectiveness of Traditional Chinese Medicinal herbs for diabetic foot:a systematic review and Meta-analysis显示文摘OBJECTIVE: To evaluate the safety and effectiveness of traditional Chinese medicinal herbs(TCMHs) as an adjunctive treatment for diabetic foot(DF).METHODS: The sources used were Pub Med(1966 to August 2015), the Cochrane Library(1988 to August 2015), the Excerpta Medica Database(1974 to August 2015), Wiley(1807 to August 2015), Ovid(1988 to August 2015), Clinical Trials.gov(1993 to August 2015), the Cochrane Central Register of Controlled Trials(1966 to August 2015), China Science and Technology Journal Database(1994 to August2015), Chi CTR(2007 to August 2015), Sino Med(1978 to August 2015), the China National Knowledge Infrastructure(1984 to August 2015), Wanfang Data Knowledge Service Platform(1998 to August 2015), and the Traditional Chinese Medical Literature Analysis and Retrieval System(TCMLARS)(1984 to August 2015). Studies were identified and selected, and the data were extracted by two independent reviewers. The Cochrane Risk of Bias tool was used to assess the quality of studies. Revman 5.2 software was used for data synthesis and analysis.RESULTS: Sixteen studies were included based on the selection criteria. Of these, seven studies had low bias risk and one had high bias risk. In the overall analysis, TCMHs resulted in a significantly higher total effective rate(OR 5.08; 95% CI 3.50 to7.36; P < 0.000 01), cure rate(OR 2.12; 95% CI1.63 to 2.77; P < 0.000 01), and shorter time to ulcer healing(SMD-0.64; 95% CI-0.89 to-0.40;P < 0.000 01) when compared with non-TCMHs treated DF. The analysis also revealed that significantly fewer amputations occurred in TCMHs patients(OR 0.36; 95% CI 0.20 to 0.65; P = 0.0007).Sensitivity analysis indicated that the findings of the Meta-analysis were robust to study quality,and the funnel plot of the Egger test showed no publication bias.CONCLUSION: TCMHs intervention appears to be more effective for DF, with a similar safety profile,when compared with non-TCMHs treatments, although this result requires further verification with more well-designed studies. | Chen Shuo Ma Jianwei Xu Limei Niu Tianhui Dong Jing Liu Wenjun Han Qi | 2017 | Journal of Traditional Chinese Medicine2017，37，6： | 5 |
| 15 | Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety. | Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 4 |
| 16 | Distribution and sources of polycyclic aromatic hydrocarbons and phthalic acid esters in water and surface sediment from the Three Gorges Reservoir显示文摘After the impoundment of the Three Gorges Reservoir(TGR), the hydrological situation of the reservoir has changed greatly. The concentration and distribution of typical persistent organic pollutants in water and sediment have also changed accordingly. In this study, the concentration, distribution and potential sources of 16 polycyclic aromatic hydrocarbons(PAHs) and 6 phthalic acid esters(PAEs) during the water drawdown and impoundment periods were investigated in water and sediment from the TGR. According to our results, PAHs and PAEs showed temporal and spatial variations. The mean ΣPAH and ΣPAE concentrations in water and sediment were both higher during the water impoundment period than during the water drawdown period. The water samples from the main stream showed larger ΣPAH concentration fluctuations than those from tributaries. Both the PAH and PAE concentrations meet the Chinese national water environmental quality standard(GB 3838-2002). PAH monomers with 2–3 rings and 4 rings were dominant in water, and 4-ring and 5–6-ring PAHs were dominant in sediment. Di-n-butyl phthalate(DBP) and di-2-ethylhexyl phthalate(DEHP)were the dominant PAE pollutants in the TGR. DBP and DEHP had the highest concentrations in water and sediment, respectively. The main source of PAHs in water from the TGR was petroleum and emissions from coal and biomass combustion, whereas the main sources of PAHs in sediments included coal and biomass combustion, petroleum, and petroleum combustion. The main source of PAEs in water was domestic waste, and the plastics and heavy chemical industries were the main sources of PAEs in sediment. | Li Lin Lei Dong Xiaoyang Meng Qingyun Li Zhuo Huang Chao Li Rui Li Wenjun Yang John Crittenden | 2018 | Journal of Environmental Sciences2018，30，7： | 4 |
| 17 | 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 |
| 18 | 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 |

| 20 | 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 |
