| 1 | The impacts of conservation agriculture on crop yield in China depend on specific practices, crops and cropping regions显示文摘For smooth and wide application of conservation agriculture(CA), remaining uncertainties about its impacts on crop yield need to be reduced. Based on previous field experiments in China, a meta-analysis was performed to quantify the actual impacts of CA practices(NT: no/reduced-tillage only, CTSR: conventional tillage with straw retention, NTSR: NT with straw retention) on crop yields as compared to conventional tillage without straw retention(CT).Although CA practices increased crop yield by 4.6% on average, there were large variations in their impacts. For each CA practice, CTSR and NTSR significantly increased crop yield by 4.9%and 6.3%, respectively, compared to CT. However, no significant effect was found for NT. Among ecological areas, significant positive effects of CA practices were found in areas with an annual precipitation below 600 mm. Similar effects were found in areas with annual mean air temperature above 5 °C. For cropping regions, CA increased crop yield by 6.4% and 5.5%compared to CT in Northwest and South China, respectively, whereas no significant effects were found in the North China and Northeast China regions. Among crops, the positive effects of CA practices were significantly higher in maize(7.5%) and rice(4.1%) than in wheat(2.9%). NT likely decreased wheat yield. Our results indicate that there are great differences in the impacts of CA practices on crop yield, owing to regional variation in climate and crop types. CA will most likely increase maize yield but reduce wheat yield. It is strongly recommended to apply CA with crop straw retention in maize cropping areas and seasons with a warm and dry climate pattern. | Chengyan Zheng Yu Jiang Changqing Chen Yanni Sun Jinfei Feng Aixing Deng Zhenwei Song Weijian Zhang | 2014 | The Crop Journal2014，2，5： | 15 |
| 2 | Organic amendments increase corn yield by enhancing soil resilience to climate change显示文摘A 22-year field experiment was conducted in Gongzhuling, Jilin province, China to investigate corn yield response to fertilization practice. Compared to an unfertilized control(CK), all fertilization treatments, including inorganic nitrogen fertilizer only(N), balanced inorganic fertilizers(NPK), NPK plus corn straw(SNPK), and NPK plus farmyard manure(MNPK), resulted in significant increases in corn yield. However, only organic matter amendments sustained increasing yield trends, with annual rates of 0.137 and 0.194 t ha-1for the SPNK and MNPK treatments, respectively(P < 0.05). During the 22 years, the daily mean, maximum and minimum temperatures increased by 0.50, 0.53, and 0.46 °C per decade, whereas precipitation displayed no significant change but showed large seasonal variation. According to a regression analysis, increased air temperature exerted positive effects on corn yields under the SNPK and the MNPK treatments. Under both treatments,soil organic carbon contents and soil nutrient availabilities increased significantly compared to their initial levels in 1990, whereas soil bulk density and total porosity changed slightly under the two treatments, which showed higher soil water storage than other treatments. In contrast, significant increases in soil bulk density and decreases in soil total porosity and soil nutrient availability were observed under the CK, N and NPK treatments. The contributions of soil fertility to corn yield were 28.4%, 37.9%, 38.4%, 39.0%,and 42.9% under CK, N, NPK, SNPK, and MNPK treatments, respectively, whereas climate changes accounted for 27.0%, 14.6%, 12.4%, 11.8%, and 10.8%. These results indicate that, in Northeast China, organic matter amendments can mitigate negative and exploit positive effects of climate change on crop production by enhancing soil quality. | Zhenwei Song Hongjun Gao Ping Zhu Chang Peng Aixing Deng Chengyan Zheng Md Abdul Mannaf Md Nurul Islam Weijian Zhang | 2015 | The Crop Journal2015，3，2： | 8 |
| 3 | Cage slip characteristics of a cylindrical roller bearing with a trilobe-raceway显示文摘Based on dynamic analysis of rolling bearings, the nonlinear dynamic differential equations of a cylindrical roller bearing with a trilobe-raceway were established and solved by the GSTIFF(gear stiff) integer algorithm with a variable step. The influences of structural parameters and the tolerance of the trilobe-raceway, working conditions of the bearing, and the outer ring installation method on cage slip characteristics were investigated. The results show that:(i) The cage slip ratio and bearing rating life of a cylindrical roller bearing with a trilobe-raceway would reduce when the low-radius(radius of the outer raceway contour at the lowest point) and D-value(difference value between the high and low points of the outer raceway contour) decrease, and the former(low-radius) contributes more significantly.(ii) The cage slip ratio of a cylindrical roller bearing with a trilobe-raceway rises with the increase of the bearing speed, and decreases with the increase of the radial force; the variation range increases with the increase of the low-radius.(iii) When the installation angle of the outer ring increases in a period, the cage slip ratio remains unchanged while the bearing rating life rises up a little. Therefore, when installing a cylindrical roller bearing with a trilobe-raceway, the location of the maximum radius shall be under that of the radial force to improve the bearing rating life.(iv) With the increase of the roundness of the base circle where the radius of the lowest points of the trilobe-raceway contour locates, the cage slip ratio rises gradually and the bearing rating life decreases. | Sier DENG Yujia LU Wenhu ZHANG Xue SUN Zhenwei LU | 2018 | Chinese Journal of Aeronautics2018，31，2： | 7 |
| 4 | Nuclear Aurora kinase A switches m^(6)A reader YTHDC1 to enhance an oncogenic RNA splicing of tumor suppressor RBM4显示文摘Aberrant RNA splicing produces alternative isoforms of genes to facilitate tumor progression,yet how this process is regulated by oncogenic signal remains largely unknown.Here,we unveil that non-canonical activation of nuclear AURKA promotes an oncogenic RNA splicing of tumor suppressor RBM4 directed by m^(6)A reader YTHDC1 in lung cancer.Nuclear translocation of AURKA is a prerequisite for RNA aberrant splicing,specifically triggering RBM4 splicing from the full isoform(RBM4-FL)to the short isoform(RBM4-S)in a kinase-independent manner. | SiSi Li YangFan Qi JiaChuan Yu YuChao Hao Bin He MengJuan Zhang ZhenWei Dai TongHui Jiang SuYi Li Fang Huang Ning Chen Jing Wang MengYing Yang DaPeng Liang Fan An JinYao Zhao WenJun Fan YuJia Pan ZiQian Deng YuanYuan Luo Tao Guo Fei Peng ZhiJie Hou ChunLi Wang FeiMeng Zheng LingZhi Xu Jie Xu QingPing Wen BiLian Jin Yang Wang Quentin Liu | 2022 | Signal Transduction and Targeted Therapy2022，7，5： | 4 |
| 5 | CMOS-compatible all-optical modulator based on the saturable absorption of graphene显示文摘Graphene resting on a silicon-on-insulator platform offers great potential for optoelectronic devices.In the paper,we demonstrate all-optical modulation on the graphene-silicon hybrid waveguides(GSHWs)with tens of micrometers in length.Owing to strong interaction between graphene and silicon strip waveguides with compact light confinement,the modulation depth reaches 22.7%with a saturation threshold down to 1.38 pJ per pulse and a 30-μm-long graphene pad.A response time of 1.65 ps is verified by a pump-probe measurement with an energy consumption of 2.1 pJ.The complementary metal-oxide semiconductor compatible GSHWs with the strip configuration exhibit great potential for ultrafast and broadband all-optical modulation,indicating that employing two-dimensional materials has become a complementary technology to promote the silicon photonic platform. | HONG WANG NINGNING YANG LIMIN CHANG CHAOBIAO ZHOU SHIYU LI MENG DENG ZHENWEI LI QIANG LIU CHI ZHANG ZHIYONG LI YI WANG | 2020 | Photonics Research2020，8，4： | 4 |

| 8 | Applications of chitosan-based biomaterials:a focus on dependent antimicrobial properties显示文摘Marine-derived chitosan has been widely examined for its use in developing biomedical materials.Not only is it non-toxic,biocompatible,and degradable,it has also shown unique antimicrobial properties.The antimicrobial properties of chitosan are restricted by neutral and physiological conditions because it is insoluble in water and its pKa values is 6.5.One solution to this problem is to graft chemically modified groups onto the backbone of chitosan.The aim of this paper is to review the mode of antimicrobial action of chitosan and chitosan derivatives.Using chitosan alone may not meet the demands of various applications.However,the introduction of additional polymers and antimicrobial agents is commonly used to enhance the antimicrobial potential of chitosan-based biomaterials.Chitosan-based composite biomaterials have been developed that allow diversified formulations to broaden applications,including nanoparticles,hydrogels,films,sponges,fibers,or even microspheres.These along with recent advances on chitosan-based composite biomaterials used for wound healing,food packaging,textile sector,3D printing and dental materials,were reviewed in detail. | Zhenwei Deng Ting Wang Xiguang Chen Ya Liu | 2020 | Marine Life Science & Technology2020，2，4： | 1 |
| 9 | Hard-carbon hybrid Li-ion/metal anode enabled by preferred mesoporous uniform lithium growth mechanism显示文摘To achieve high energy density in lithium batteries,the construction of lithium-ion/metal hybrid anodes is a promising strategy.In particular,because of the anisotropy of graphite,hybrid anode formed by graphite/Li metal has low transport kinetics and is easy to causes the growth of lithium dendrites and accumulation of dead Li,which seriously affects the cycle life of batteries and even causes safety problems.Here,by comparing graphite with two types of hard carbon,it was found that hybrid anode formed by hard carbon and lithium metal,possessing more disordered mesoporous structure and lithophilic groups,presents better performance.Results indicate that the mesoporous structure provides abundant active site and storage space for dead lithium.With the synergistic effect of this structure and lithophilic functional groups(–COOH),the reversibility of hard carbon/lithium metal hybrid anode is maintained,promoting uniform deposition of lithium metal and alleviating formation of lithium dendrites.The hybrid anode maintains a 99.5%Coulombic efficiency(CE)after 260 cycles at a specific capacity of 500 m Ah/g.This work provides new insights into the hybrid anodes formed by carbon-based materials and lithium metal with high specific energy and fast charging ability. | Fang Yan Yan Liu Yuan Li Yan Wang Zicen Deng Meng Li Zhenwei Zhu Aohan Zhou Ting Li Jingyi Qiu Gaoping Cao Shaobo Huang Biyan Wang Hao Zhang | 2024 | Journal of Energy Chemistry2024，88，1： | 0 |
| 10 | Crystal face dependent intrinsic wettability of metal oxide surfaces显示文摘Knowledge of intrinsic wettability at solid/liquid interfaces at the molecular level perspective is significant in understanding crucial progress in some fields,such as electrochemistry,molecular biology and earth science.It is generally believed that surface wettability is determined by the surface chemical component and surface topography.However,when taking molecular structures and interactions into consideration,many intriguing phenomena would enrich or even redress our understanding of surface wettability.From the perspective of interfacial water molecule structures,here,we discovered that the intrinsic wettability of crystal metal oxide is not only dependent on the chemical components but also critically dependent on the crystal faces.For example,the(1I02)crystal face ofα-Al2O3 is intrinsically hydrophobic with a water contact angle near 90°,while another three crystal faces are intrinsically hydrophilic with water contact angles<65°.Based on surface energy analysis,it is found that the total surface energy,polar component and Lewis base portion of the hydrophobic crystal face are all smaller than the other three hydrophilic crystal faces indicating that they have different surface states.DFT simulation further revealed that the adsorbed interfacial water molecules on each crystal face hold various orientations.Herein,the third crucial factor for surface wettability from the perspective of the molecular level is presented,that is the orientations of adsorbed interfacial water molecules apart from the macro-level chemical component and surface topography.This study may serve as a source of inspiration for improving wetting theoretical models and designing controllable wettability at the molecular/atomic level. | Zhongpeng Zhu Zhenwei Yu Frank FYun Deng Pan Ye Tian Lei Jiang Xiaolin Wang | 2021 | National Science Review2021，8，1： | 0 |

| 12 | Monitoring the pH fluctuation of lysosome under cell stress using a near-infrared ratiometric fluorescent probe显示文摘Cell stress responses are associated with numerous diseases including diabetes, neurodegenerative diseases, and cancer. Several events occur under cell stress, in which, are protein expression and organellespecific pH fluctuation. To understand the lysosomal pH variation under cell stress, a novel NIR ratiometric pH-responsive fluorescent probe(BLT) with lysosomes localization capability was developed.The quinoline ring of BLT combined with hydrogen ion which triggered the rearrangement of π electrons conjugated at low pH medium, meanwhile, the absorption and fluorescent spectra of BLT showed a red-shifts, which gived a ratiometric signal. Moreover, the probe BLT with a suitable p Kavalue has the potential to discern changes in lysosomal pH, either induced by heat stress or oxidative stress or acetaminophen-induced(APAP) injury stress. Importantly, this ratiometric fluorescent probe innovatively tracks pH changes in lysosome in APAP-induced liver injury in live cells, mice, and zebrafish. The probe BLT as a novel fluorescent probe possesses important value for exploring lysosomal-associated physiological varieties of drug-induced hepatotoxicity. | Lijuan Gui Kaizhen Wang Yuxin Wang Jun Yan Xian Liu Jingxuan Guo Ji Liu Dawei Deng Haiyan Chen Zhenwei Yuan | 2023 | Chinese Chemical Letters2023，34，3： | 0 |
