| 1 | Gaseous hydrogen storage properties of Mg-Y-Ni-Cu alloys prepared by melt spinning显示文摘For purpose of promoting the hydrogen absorption and desorption thermodynamics and kinetics properties of Mg-Ni-based alloys, partially substituting Y and Cu for Mg and Ni respectively and melt spinning technique were applied for getting Mg25-xYxNi9 Cu(χ = 0-7) alloys. Their microstructures and phases were characterized with the help of X-ray diffraction and transmission electron microscopy. Their hydrogen absorbing and desorbing properties were tested by a Sievert apparatus, DSC, and TGA, which were connected with a H2 detector. In order to estimate the dehydrogenation activation energy of alloy hydride, both Arrhenius and Kissinger methods were applied for calculation. It is found that their hydriding kinetics notably declines, however, their hydrogen desorption kinetics conspicuously improves, with spinning rate and Y content increasing. Their hydrogen desorption activation energy markedly decreases under the same constraint, and it is found that melt spinning and Y substituting Mg improve the real driving force for dehydrogenation. As for the tendency of hydrogen absorption capacity,it presents an elevation firstly and soon after a decline with the rising of spinning rate, however, it always lowers with Y content growing. With Y content and spinning rate increasing, their thermodynamic parameters(△H and △S absolute values) visibly decrease, and the starting hydrogen desorption temperatures of alloy hydrides obviously lower. | Yanghuan Zhang Yaqin Li Wei Zhang Zeming Yuan Zhonghui Hou Yan Qi Shihai Guo | 2019 | Journal of Rare Earths2019，37，7： | 2 |
| 2 | Regulating electronic structure of two-dimensional porous Ni/Ni_(3)N nanosheets architecture by Co atomic incorporation boosts alkaline water splitting显示文摘Interfacial engineering is a powerful method to improve the bifunctional electrocatalytic performance of pure phase catalysts.While it is expected to further optimize the electronic configuration of heterojunctions to boost the reaction kinetics in hydrogen/oxygen evolution reaction(HER/OER),but remains a challenge.Herein,a novel in situ hybrid heterojunction strategy is developed to construct 2D porous Co-doped Ni/Ni_(3)N heterostructure nanosheets(Co-Ni/Ni_(3)N)by pyrolysis of partially cobalt substituted nickel-zeolitic imidazolate framework(CoNi-ZIF)nanosheets under NH3 atmosphere.A combined experimental and theoretical studies manifest that the hybrid heterostructures can display regulative electronic states and downshift d-band center from the Fermi level,as well as optimize the adsorption energy of reaction intermediates,thus reducing the thermodynamic energy barriers and accelerating the catalytic kinetics.Consequently,benefitting from the optimized electronic configuration,hierarchical hollow nanosheets architecture,and abundant doped heterojunctions,the hybrid Co-Ni/Ni_(3)N heterostructure catalyst exhibits efficient catalytic activity for both HER(60 mV)and OER(322 mV)at 10 mA cm^(-2)in alkaline media,which is 105 and 47 mV lower than that of pure Ni_(3)N,respectively.The electrochemically active surface area of Co-Ni/Ni_(3)N is two times higher than that of Ni3N.Furthermore,the coupled practical water electrolyzer requires a low voltage of 1.575 V to reach 10 mA cm^(-2),and it can be driven by a 1.5 V battery.This work highlights the interface engineering guidance for the rational establishment of hybrid interfaces by electronic modulation of interfacial effect for alkaline water splitting. | Kaixi Wang Yingying Guo Zhonghui Chen Donghai Wu Shouren Zhang Baocheng Yang Jianan Zhang | 2022 | InfoMat2022，4，6： | 1 |

| 4 | Structure and hydrogen storage characteristics of as-spun Mg-Y-Ni-Cu alloys显示文摘Experimental alloys with compositions of Mg(25-x)YxNi9Cu(x=0,1,3,5,7)have been successfully prepared through melt spinning method.The phase compositions and microstructures were measured by X-Ray diffraction(XRD)and high-resolution transmission electron microscopy(HRTEM).The de-/hydrogenation properties were measured by utilizing Sievert apparatus,differential scanning calorimetry(DSC)and thermal gravimetric analyzer(TGA)connected with a H2 detector.The Arrhenius and Kissinger methods were adopted to calculate their dehydrogenation activation energies.The results show that hydrogen absorption kinetics of the alloys notably decline while their hydrogen desorption kinetics conspicuously improve with spinning rate increasing.The dehydrogenation activation energy markedly decreases with spinning rate increasing,which makes the hydrogen desorption kinetics improve.The thermodynamic parameters(H and S absolute values)clearly decrease with spinning rate increasing.The hydrogen absorption capacity exhibits different trends with spinning rate rising.Specifically,hydrogen absorption capacity increases at the beginning and declines later for Y1 alloy,but that of Y7 alloy always decreases with spinning rate growing. | Yanghuan Zhang Pengpeng Wang Zhonghui Hou Zeming Yuan Yan Qi Shihai Guo | 2019 | Journal of Materials Science & Technology2019，35，8： | 1 |

| 7 | Stretchable polymer composites with ultrahigh piezoelectric performance显示文摘Flexible piezoelectric materials capable of withstanding large deformation play key roles in flexible electronics.Ferroelectric ceramics with a high piezoelectric coefficient are inherently brittle,whereas polar polymers exhibit a low piezoelectric coefficient.Here we report a highly stretchable/compressible piezoelectric composite composed of ferroelectric ceramic skeleton,elastomer matrix and relaxor ferroelectric-based hybrid at the ceramic/matrix interface as dielectric transition layers,exhibiting a giant piezoelectric coefficient of 250 picometers per volt,high electromechanical coupling factor keff of 65%,ultralow acoustic impedance of 3MRyl and high cyclic stability under 50%compression strain.The superior flexibility and piezoelectric properties are attributed to the electric polarization and mechanical load transfer paths formed by the ceramic skeleton,and dielectric mismatch mitigation between ceramic fillers and elastomer matrix by the dielectric transition layer.The synergistic fusion of ultrahigh piezoelectric properties and superior flexibility in these polymer composites is expected to drive emerging applications in flexible smart electronics. | Tongxiang Tang Zhonghui Shen Jian Wang Shiqi Xu Jiaxi Jiang Jiahui Chang Mengfan Guo Youjun Fan Yao Xiao Zhihao Dong Houbing Huang Xiaoyan Li Yihui Zhang Danyang Wang Long-Qing Chen Ke Wang Shujun Zhang Ce-Wen Nan Yang Shen | 2023 | National Science Review2023，10，8： | 1 |

| 9 | Effects of plant protection UAV-based spraying on the vertical distribution of droplet deposition on Japonica rice plants in Northeast China显示文摘In order to study the regularity of the vertical distribution of droplet deposition on rice plants during pesticide spraying operated by a low-flying multi-rotor plant protection unmanned aviation vehicle(UAV),water-sensitive spray cards were placed on the leaves at the top,in the middle,and at the bottom of rice plants to acquire data on droplet deposition.In this study,a suspension containing tricylazole and hexaconazole was used in the spraying.The water-sensitive spray cards were analyzed by the droplet deposition processing software iDAS to obtain the vertical distribution of the droplets sprayed by the plant protection UAV.The results showed that (1)significant variation was found in the coverage of the droplets in different vertical positions of the rice plants.Within the effective spray width,the best coverage of the droplets was found in the area just below the rotors,whereas the coverage of areas farther away from the rotors was poor.For the different vertical positions of the rice plants,the overall droplet coverage was 58.38%at the top,33.55%in the middle,and 11.34%at the bottom of the plants;(2)for all vertical positions,the average size of the droplets ranged between 110μm and 140μm,which was suitable for the control of plant diseases and insect pests.The highest droplet density was found at the top of the plants,and the distribution of the droplet density was similar in the middle and at the bottom of the rice plants;(3)the diffusion ratio at the top of the rice plants(0.84)was better than that in the middle(0.57)and at the bottom(0.37).The overall relative span could meet the requirements for the actual application.Except for the position in the middle of the plants,the relative span for the other positions of the plants was over 0.67,which is the standard value.This study demonstrated the distribution regularity of droplet deposition along with the vertical direction of rice plants during UAV-based spraying,which is of guiding significance for the use of UAVs in plant protection,the improvement of chemical utilization efficiency,and the reduction of pesticide and fertilizer pollution. | Yingli Cao Fenghua Yu Tongyu Xu Wen Du Zhonghui Guo Haiyan Zhang | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 1 |
| 10 | Electrochemiluminescence Sensor for Cancer Cell Detection Based on H_(2)O_(2)-Triggered Stimulus Response System显示文摘A H_(2)O_(2)-triggered stimulus response electrochemiluminescence(ECL)sensor for sensitive detection of cancer cells using mesoporous silica nanoparticles(MSNs)has been proposed.ECL signal-generating molecules(Ru(phen)32+)were encap-sulated into phenylboronic acid group-functionalized MSNs(PBA-MSNs)porous and capped by polyhydroxy functioned Au nanoparticles(AuNPs)through the interaction of carbohydrate-boronic acid first.Brunauer-Emmett-Teller(BET)and transmission electron microscopy(TEM)were applied to characterize the materials.The proposed controlled release sensing platform shows approximately no leakage from the mesoporrs of MSNs after a long time of storage.Cancer cells are initially incubated with the functionalized MSNs and then treated with ascorbic acid to endogenously produce H_(2)O_(2).Arylboronic esters in the MSNs surface can be oxidized by the produced H_(2)O_(2),causing the releasing of the molecule from MSNs and increased ECL signal.This technique displayed an excellent measurement for the breast cancer cells’sensitive diagnosis with a detection limit of 208 cells/mL.The phenomenon suggests that this sensing platform may be potentially applied for breast cancer sensitive detection in the future. | Yu Chen Zhonghui Chen Lishan Fang Aibin Weng Fang Luo Longhua Guo Bin Qiu Zhenyu Lin | 2020 | Journal of Analysis and Testing2020，4，2： | 0 |

| 12 | iEarth:an interdisciplinary framework in the era of big data and AI for sustainable development显示文摘The United Nations 2030 Agenda for Sustainable Development provides a shared blueprint for peace and prosperity,addressing environmental,social,and economic challenges through its 17 Sustainable Development Goals(SDGs).Over the past five to seven years,countries worldwide made collective commitments to achieve the SDGs[1].However,implementing the SDGs agenda faces several challenges,such as insufficient data,unreliable methods,ambiguous indicators,interlinked and constrained targets,diverse localization issues,and other constraints on the pace of progress[2].The success of the SDGs relies on the coordinated development of environmental,social and economic dimensions,highlighting the urgent need for more transformative and comprehensive countermeasures[3]. | Peng Gong Huadong Guo Bin Chen Fang Chen Guojun He Dong Liang Zhonghui Liu Zhongchang Sun Jin Wu Zhenci Xu Dongmei Yan Hongsheng Zhang | 2023 | National Science Review2023，10，8： | 0 |
| 13 | Current strategies for improving limitations of proteolysis targeting chimeras显示文摘Proteolysis targeting chimeras(PROTACs)are bifunctional degrader molecules via hijacking the ubiquitinproteasome system(UPS)to specifically eliminate targeted proteins.PROTACs have gained momentum as a new modality of attractive technologies in the drug discovery landscape,since it allows to degrade disease-related proteins effectively.Although some PROTACs drugs reached the clinical research,they are still facing some bottlenecks and challenges that should not be neglected,such as poor oral bioavailability and potential toxic side effects.To overcome these limitations,herein,we provide an overview of recent strategies for improving the durability of PROTACs by enhancing cell permeability and reducing toxic side effects.Meanwhile,the impact of these strategies on improving oral bioavailability as well as their advantages and drawbacks will also be discussed.This review will give a useful reference toolbox for PROTACs design and further promote its clinical application. | Chunlan Pu Shirui Wang Lei Liu Zhonghui Feng Hongjia Zhang Qianyuan Gong Yueshan Sun Yuanbiao Guo Rui Li | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
| 14 | Transcriptional regulation of the immune checkpoints PD-1 and CTLA-4显示文摘Immunotherapy targeting immune checkpoints(ICs)has revolutionized the field of cancer treatment.ICs are a group of proteins that provide stimulatory or inhibitory signals to regulate T-cell activation,tolerance,and exhaustion.To date,some immune checkpoint inhibitors(ICIs)targeting TIM-3,LAG-3,TIGIT,and VISTA are under investigation for their clinical applications.However,only ICIs against CTLA-4,PD-1,and PD-L1 are approved by the FDA and widely used as first-line or second-line treatments for multiple cancer types.CTLA-4 and PD-1 are coinhibitory receptors that are mainly expressed by T cells. | Jing Guo Zhonghui Xue Lie Wang | 2022 | Cellular & Molecular Immunology2022，19，7： | 0 |
