| 1 | Selective hydrogenation of CO2 to methanol over Ni/In2O3 catalyst显示文摘An In2O3 supported nickel catalyst has been prepared by wet chemical reduction with sodium borohydride(NaBH4) as a reducing agent for selective hydrogenation of carbon dioxide to methanol. Highly dispersed Ni species with intense Ni-In2O3 interaction and enhanced oxygen vacancies have been achieved.The highly dispersed Ni species serve as the active sites for hydrogen activation and hydrogen spillover.Abundant H adatoms are thereby generated for the oxygen vacancy creation on the In2O3 surface. The enhanced surface oxygen vacancies further lead to improved CO2 conversion. As a result, an effective synergy between the active Ni sites and surface oxygen vacancies on In2O3 causes a superior catalytic performance for CO2 hydrogenation with high methanol selectivity. Carbon monoxide is the only by product detected. The formation of methane can be ignored. When the reaction temperature is lower than 225 ℃,the selectivity of methanol is 100%. It is higher than 64% at the temperature range between 225 ℃ and 275 ℃. The methanol selectivity is still higher than 54% at 300 ℃ with a CO2 conversion of 18.47% and a methanol yield of 0.55 gMeOHg-1cath-1(at 5 MPa). The activity of Ni/In2O3 is higher than most of the reported In2O3-based catalysts. | Xinyu Jia Kaihang Sun Jing Wang Chenyang Shen Chang-jun Liu | 2020 | Journal of Energy Chemistry2020，29，11： | 13 |
| 2 | Paragraph Vector Representation Based on Word to Vector and CNN Learning显示文摘Document processing in natural language includes retrieval,sentiment analysis,theme extraction,etc.Classical methods for handling these tasks are based on models of probability,semantics and networks for machine learning.The probability model is loss of semantic information in essential,and it influences the processing accuracy.Machine learning approaches include supervised,unsupervised,and semi-supervised approaches,labeled corpora is necessary for semantics model and supervised learning.The method for achieving a reliably labeled corpus is done manually,it is costly and time-consuming because people have to read each document and annotate the label of each document.Recently,the continuous CBOW model is efficient for learning high-quality distributed vector representations,and it can capture a large number of precise syntactic and semantic word relationships,this model can be easily extended to learn paragraph vector,but it is not precise.Towards these problems,this paper is devoted to developing a new model for learning paragraph vector,we combine the CBOW model and CNNs to establish a new deep learning model.Experimental results show that paragraph vector generated by the new model is better than the paragraph vector generated by CBOW model in semantic relativeness and accuracy. | Zeyu Xiong Qiangqiang Shen Yijie Wang Chenyang Zhu | 2018 | Computers, Materials & Continua2018，，5： | 5 |
| 3 | Preparation of pitch precursor with excellent spinnability for general-purpose carbon fibre using coal tar pitch as raw material显示文摘Tetrahydrofuran(THF) extract of coal tar pitch(CTP) was used instead of blending CTP with pretreated pyrolysis fuel oil to prepare an isotropic pitch precursor with excellent spinnability for general-purpose carbon fibre through bromination-dehydrobromination. The feasibility and effectiveness of synthesising an isotropic pitch precursor derived from THF-soluble(CTP-THFs) is demonstrated in this study.The results show that CTP-THFs contains more light components than CTP;CTP-THFs and CTP monomer proportions were 62.52% and 45.32%, respectively. However, based on comparisons of CTP-THFsBr0 and CTPBr0 characterisations, CTP-THFs exhibits better polycondensation than CTP. Bromination-dehydrobro mination promotes polycondensation of pitch precursors, leading to greater carbon aromaticity in CTP-THFsBr5, CTP-THFsBr10, and CTP-THFsBr15 than that in CTP-THFsBr0 and CTPBr0. CTP-THFsBr5 and CTP-THFsBr10 have excellent spinnability even with softening points as high as 230 ℃. The pericondensed carbon and carbon aromaticity of CTP-THFsBr5 and CTP-THFsBr10 are high owing to the higher degree of polycondensation;however, they still possess a more linear molecular structure. The as-prepared carbon fibre exhibits homogeneity and uniformity, and the mechanical performance is comparable with that of commercial general-purpose carbon fibre products. | Jinchang Liu Chenyang Shen Lujie Huang Tinghao Fang Yaping Li Dingcheng Liang Qiang Xie | 2023 | Chinese Journal of Chemical Engineering2023，54，2： | 3 |

| 5 | The feasibility study of the indium oxide supported silver catalyst for selective hydrogenation of CO_(2)to methanol显示文摘Silver catalyst has been extensively investigated for photocatalytic and electrochemical CO_(2) reduction.However,its high activity for selective hydrogenation of CO_(2) to methanol has not been confirmed.Here,the feasibility of the indium oxide supported silver catalyst was investigated for CO_(2) hydrogenation to methanol by the density functional theoretical(DFT)study and then by the experimental investigation.The DFT study shows there exists an intense Ag-In_(2)O_(3) interaction,which causes silver to be positively charged.The positively charged Ag species changes the electronic structure of the metal,facilitates the formation of the Ag-In_(2)O_(3) interfacial site for activation and dissociation of carbon dioxide.The promoted CO_(2) dissociation leads to the enhanced methanol synthesis via the CO hydrogenation route as CO_(2)^(*)→CO^(*)→HCO^(*)→H_(2)CO^(*)→H_(3)CO^(*)→H_(3)COH^(*).The Ag/In_(2)O_(3)catalyst was then prepared using the deposition-precipitation method.The experimental study confirms the theoretical prediction.The methanol selectivity of CO_(2) hydrogenation on Ag/In_(2)O_(3) reaches 100.0%at reaction temperature of 200℃.It remains more than 70.0%between 200 and 275℃.At 300℃and 5 MPa,the methanol selectivity still keeps 58.2%with a CO_(2) conversion of 13.6%and a space-time yield(STY)of methanol of 0.453 g_(methanol)g_(cat)^(-1)h^(-1),which is the highest methanol STY ever reported for silver catalyst.The catalyst characterization confirms the intense Ag-In_(2)O_(3)interaction as well,which causes high Ag dispersion,increases and stabilizes the oxygen vacancies and creates the active Ag-In_(2)O_(3)interfacial site for the enhanced CO_(2)hydrogenation to methanol. | Kaihang Sun Zhitao Zhang Chenyang Shen Ning Rui Chang-jun Liu | 2022 | Green Energy & Environment2022，7，4： | 2 |
| 6 | Synergistic effect of the metal-support interaction and interfacial oxygen vacancy for CO_(2) hydrogenation to methanol over Ni/In_(2)O_(3) catalyst:A theoretical study显示文摘Indium oxide supported nickel catalyst has been experimentally confirmed to be highly active for CO_(2) hydrogenation towards methanol.In this work,the reaction mechanism for CO_(2) hydrogenation to methanol has been investigated on a model Ni/In_(2)O_(3) catalyst,i.e.,Ni_(4)/In_(2)O_(3),via the density functional theory(DFT)study.Three possible reaction pathways,i.e.,the formate pathway,CO hydrogenation and the reverse water-gas-shift(RWGS)pathways,have been examined on this model catalyst.It has been demonstrated that the RWGS pathway is the most theoretically-favored for CO_(2) hydrogenation to methanol.The complete RWGS pathway follows CO_(2)+6 H→COOH+5 H→CO+H_(2)O+4 H→HCO+H_(2)O+3 H→H_(2)CO+H_(2)O+2 H→H_(3)CO+H_(2)O+H→H_(3)COH+H_(2) O.Furthermore,it has been also proved that the interfacial oxygen vacancy can serve as the active site for boosting the CO_(2) adsorption and charge transfer between the nickel species and indium oxide,which synergistically promotes the consecutive CO_(2) hydrogenation towards methanol. | Chenyang Shen Qianqian Bao Wenjuan Xue Kaihang Sun Zhitao Zhang Xinyu Jia Donghai Mei Chang-jun Liu | 2022 | Journal of Energy Chemistry2022，31，2： | 2 |
| 7 | Human health risk assessment of groundwater nitrate at a two geomorphic units transition zone in northern China显示文摘To assess groundwater nitrate contamination and its human health risks,489 unconfined groundwater samples were collected and analyzed from Zhangjiakou,northern China.The spatial distribution of principle hydrogeochemical results showed that the average concentrations of ions in descend order was HCO3-,SO42-,Na+,Ca2+,Cl-,NO3-,Mg2+and K+,among which the NO3-concentrations were between 0.25 and 536.73 mg/L with an average of 29.72 mg/L.In total,167 out of 489 samples(34%)exceeded the recommended concentration of 20 mg/L in Quality Standard for Groundwater of China.The high NO3-concentration groundwater mainly located in the northern part and near the boundary of the two geomorphic units.As revealed by statistical analysis,the groundwater chemistry was more significantly affected by anthropogenic sources than by the geogenic sources.Moreover,human health risks of groundwater nitrate through oral and dermal exposure pathways were assessed by model,the results showed that about 60%,50%,32%and 26%of the area exceeded the acceptable level(total health index>1)for infants,children,adult males and females,respectively.The health risks for different groups of people varied significantly,ranked:infants>children>adult males>adult females,suggesting that younger people are more susceptible to nitrate contamination,while females are more resistant to nitrate contamination than males.To ensure the drinking water safety in Zhangjiakou and its downstream areas,proper management and treatment of groundwater will be necessary to avoid the health risks associated with nitrate contamination. | Huiliang Wang Keyu Lu Chenyang Shen Xiaoguang Song Bin Hu Gang Liu | 2021 | Journal of Environmental Sciences2021，33，12： | 2 |
| 8 | Nonreciprocal coherent coupling of nanomagnets by exchange spin waves显示文摘Nanomagnets are widely used to store information in non-volatile spintronic devices.Spin waves can transfer information with low-power consumption as their propagations are independent of charge transport.However,to dynamically couple two distant nanomagnets via spin waves remains a major challenge for magnonics.Here we experimentally demonstrate coherent coupling of two distant Co nanowires by fast propagating spin waves in an yttrium iron garnet thin film with sub-50 nm wavelengths.Magnons in two nanomagnets are unidirectionally phase-locked with phase shifts controlled by magnon spin torque and spin-wave propagation.The coupled system is finally formulated by an analytical theory in terms of an effective non-Hermitian Hamiltonian.Our results are attractive for analog neuromorphic computing that requires unidirectional information transmission. | Hanchen Wang Jilei Chen Tao Yu Chuanpu Liu Chenyang Guo Song Liu Ka Shen Hao Jia Tao Liu Jianyu Zhang Marco A.Cabero Z Qiuming Song Sa Tu Mingzhong Wu Xiufeng Han Ke Xia Dapeng Yu Gerrit E.W.Bauer Haiming Yu | 2021 | Nano Research2021，14，7： | 1 |
| 9 | Risk SNP-induced lncRNA-SLCCl drives colorectal cancer through activating glycolysis signaling显示文摘Long non-coding RNAs(lncRNAs)play key roles in colorectal carcinogenesis.Here,we aimed to identify the risk SNP-induced lncRNAs and to investigate their roles in colorectal carcinogenesis.First,we identified rs6695584 as the causative SNP in 1 q41 locus.The A>G mutation of rs6695584 created a protein-binding motif of BATF,altered the enhancer activity,and subsequently activated IncSLCCl expression.Further validation in two independent CRC cohorts confirmed the upregulation of IncSLCCl in CRC tissues,and revealed that increased IncSLCCl expression was associated with poor survival in CRC patients.Mechanistically,lncRNA-SLCCl interacted with AHR and transcriptionally activated HK2 expression,the crucial enzyme in glucose metabolism,thereby driving the glycolysis pathway and accelerating CRC tumor growth.The functional assays revealed that IncSLCCl induced glycolysis activation and tumor growth in CRC mediated by HK2.In addition,HK2 was upregulated in colorectal cancer tissues and positively correlated with IncSLCCl expression and patient survival.Taken together,our findings reveal a risk SNP-mediated oncogene lncRNA-SLCCl promotes CRC through activating the glycolysis pathway. | Tingting Yan Chaoqin Shen Penglei Jiang Chenyang Yu Fangfang Guo Xianglong Tian Xiaoqiang Zhu Shiyuan Lu Bingshe Han Ming Zhong Jinxian Chen Qiang Liu Yingxuan Chen Junfang Zhang Jie Hong Haoyan Chen Jing-Yuan Fang | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 1 |

| 13 | RNA m^(6)A Modification in Cancers: Molecular Mechanisms and Potential Clinical Applications显示文摘N^(6)-Methyladenosine(m^(6)A)RNA modification brings a new dawn for RNA modification researches in recent years.This posttranscriptional RNA modification is dynamic and reversible,and is regulated by methylases(“writers”),demethylases(“erasers”),and proteins that preferentially recognize m^(6)A modifications(“readers”).The change of RNA m^(6)A modification regulates RNA metabolism in eucaryon,including translation,splicing,exporting,decay,and processing.Thereby the dysregulation ofm^(6)A may lead to tumorigenesis and progression.Given the tumorigenic role of abnormalm^(6)A expression,m^(6)A regulators may function as potential clinical therapeutic targets for cancers.In this review,we emphasize on the underlying mechanisms of m^(6)A modifications in tumorigenesis and further introduce the potential m^(6)A regulators-associated therapeutic targets for tumor therapy. | Chang Gu Xin Shi Chenyang Dai Feng Shen Gaetano Rocco Jiafei Chen Zhengyu Huang Chunji Chen Chuan He Tao Huang Chang Chen | 2020 | The Innovation2020，1，3： | 0 |

| 15 | The wheat sucrose synthase gene TaSus1 is a determinant of grain number per spike显示文摘Some haplotypes of the sucrose synthase gene TaSus1 are associated with thousand-grain weight(TGW)in wheat(Triticum aestivum L.).However,no mutations have been identified within the gene to test this association.The effects of TaSus1 on grain number per spike(GNS)also are largely unknown.Our previous genome-wide association study identified TaSus-A1 as a candidate gene controlling fertile spikelet number per spike(FSN).In the present study,we generated two independent mutants for the three TaSus1 homoeologs by CRISPR/Cas9-mediated genome editing.The triple mutants displayed lower FSN,GNS,grain number per spikelet(GNST),and TGW than wild-type plants.In 306 hexaploid wheat accessions,two single-nucleotide polymorphisms in TaSus-A1 contributed differently to GNS.Introgression of the two alleles into a wheat genetic background confirmed their effects.The alleles differed in geographical distribution among the accessions. | Liping Shen Lili Zhang Changbin Yin Xiaowan Xu Yangyang Liu Kuocheng Shen He Wu Zhiwen Sun Ke Wang Zhonghu He Xueyong Zhang Chenyang Hao Jian Hou Aoyue Bi Xuebo Zhao Daxing Xu Botao Ye Xuchang Yu Ziying Wang Danni Liu Yuanfeng Hao Fei Lu Zifeng Guo | 2024 | The Crop Journal2024，12，1： | 0 |
| 16 | Design and implementation of a jellyfish otolith-inspired MEMS vector hydrophone for low-frequency detection显示文摘Detecting low-frequency underwater acoustic signals can be a challenge for marine applications.Inspired by the notably strong response of the auditory organs of pectis jellyfish to ultralow frequencies,a kind of otolith-inspired vector hydrophone(OVH)is developed,enabled by hollow buoyant spheres atop cilia.Full parametric analysis is performed to optimize the cilium structure in order to balance the resonance frequency and sensitivity.After the structural parameters of the OVH are determined,the stress distributions of various vector hydrophones are simulated and analyzed.The shock resistance of the OVH is also investigated.Finally,the OVH is fabricated and calibrated.The receiving sensitivity of the OVH is measured to be as high as−202.1 dB@100 Hz(0 dB@1 V/μPa),and the average equivalent pressure sensitivity over the frequency range of interest of the OVH reaches−173.8 dB when the frequency ranges from 20 to 200 Hz.The 3 dB polar width of the directivity pattern for the OVH is measured as 87°.Moreover,the OVH is demonstrated to operate under 10 MPa hydrostatic pressure.These results show that the OVH is promising in low-frequency underwater acoustic detection. | Renxin Wang Wei Shen Wenjun Zhang Jinlong Song Nansong Li Mengran Liu Guojun Zhang Chenyang Xue Wendong Zhang | 2021 | Microsystems & Nanoengineering2021，7，1： | 0 |
| 17 | Debris cloud structure and hazardous fragments distribution under hypervelocity yaw impact显示文摘This study investigates how the debris cloud structure and hazardous fragment distribution vary with attack angle by simulating a circular cylinder projectile hypervelocity impinging on a thin plate using the finite element-smoothed particle hydrodynamics(FE-SPH)adaptive method.Based on the comparison and analysis of the experimental and simulation results,the FE-SPH adaptive method was applied to address the hypervelocity yaw impact problem,and the variation law of the debris cloud structure with the attack angle was obtained.The screening criterion of the hazardous fragment at yaw impact is given by analyzing the debris formation obtained by the FE-SPH adaptive method,and the distribution characteristics of hazardous fragments and their relationship with the attack angle are given.Moreover,the velocity space was used to evaluate the distribution range and damage capability of asymmetric hazardous fragments.The maximum velocity angle was extended from fully symmetrical working conditions to asymmetrical cases to describe the asymmetrical debris cloud distribution range.In this range,the energy density was calculated to quantitatively analyze how much damage hazardous fragments inflict on the rear plate.The results showed that the number of hazardous fragments generated by the case near the 35°attack angle was the largest,the distribution range was the smallest,and the energy density was the largest.These results suggest that in this case,debris cloud generated by the impact had the strongest damage to the rear plate. | Chenyang Wu Qi-Guang He Xiaowei Chen Chunbo Zhang Zebin Shen | 2023 | Defence Technology(防务技术)2023，27，9： | 0 |
| 18 | Exosome/metformin-loaded self-healing conductive hydrogel rescues microvascular dysfunction and promotes chronic diabetic wound healing by inhibiting mitochondrial fission显示文摘Chronic diabetic wounds remain a globally recognized clinical challenge.They occur due to high concentrations of reactive oxygen species and vascular function disorders.A promising strategy for diabetic wound healing is the delivery of exosomes,comprising bioactive dressings.Metformin activates the vascular endothelial growth factor pathway,thereby improving angiogenesis in hyperglycemic states.However,multifunctional hydrogels loaded with drugs and bioactive substances synergistically promote wound repair has been rarely reported,and the mechanism of their combinatorial effect of exosome and metformin in wound healing remains unclear.Here,we engineered dual-loaded hydrogels possessing tissue adhesive,antioxidant,self-healing and electrical conductivity properties,wherein 4-armed SH-PEG cross-links with Ag^(+),which minimizes damage to the loaded goods and investigated their mechanism of promotion effect for wound repair.Multiwalled carbon nanotubes exhibiting good conductivity were also incorporated into the hydrogels to generate hydrogen bonds with the thiol group,creating a stable three-dimensional structure for exosome and metformin loading.The diabetic wound model of the present study suggests that the PEG/Ag/CNT-M+E hydrogel promotes wound healing by triggering cell proliferation and angiogenesis and relieving peritraumatic inflammation and vascular injury.The mechanism of the dual-loaded hydrogel involves reducing the level of reactive oxygen species by interfering with mitochondrial fission,thereby protecting F-actin homeostasis and alleviating microvascular dysfunction.Hence,we propose a drug-bioactive substance combination therapy and provide a potential mechanism for developing vascular function-associated strategies for treating chronic diabetic wounds. | Yue Zhang Meng Li Yunchuan Wang Fei Han Kuo Shen Liang Luo Yan Li Yanhui Jia Jian Zhang Weixia Cai Kejia Wang Ming Zhao Jing Wang Xiaowen Gao Chenyang Tian Baolin Guo Dahai Hu | 2023 | Bioactive Materials2023，，8： | 0 |

However, the similarity of molecule structures between small molecule donors and acceptors makes a hard regulation of their blend morphology, which will limit the efficiency. | Haojiang Shen Yi Ren Jianfeng Li Yixuan Xu Chenyang Han Wentao Zou Huajun Xu Yanna Sun Yuanyuan Kan Ke Gao | 2023 | Chinese Journal of Chemistry2023，41，6： | 0 |
| 20 | Slot-die coated large-area flexible all-polymer solar cells by nonhalogenated solvent显示文摘The slot-die coating is recognized as the most compatible method for the roll-to-roll(R2R)processing of large-area flexible organic solar cells(OSCs).However,the photovoltaic performance of the large-area flexible all-polymer solar cells was significantly lagging behind that of polymer donors with small molecule non-fullerene acceptors devices.In this work,the 1 cm^(2) flexible device of an all-polymer system,PTQ10:PYF-T-o,fabricated by slot-die coating,achieves an excellent efficiency of 11.24%via controlling the coating temperatures.It is found that,compared with the donor,the crystallinity of PYF-T-o plays a crucial role in device performance.The all-polymer flexible devices show superior mechanical bending stability,maintaining an efficiency of over 95%of the initial value during a 1000-cycle bending test. | Yi-Fan Shen Jianqi Zhang Chenyang Tian Dingding Qiu Zhixiang Wei | 2023 | Nano Research2023，16，12： | 0 |
