1Agriculture Green Development: a model for China and the world显示文摘Realizing sustainable development has become a global priority.This holds,in particular,for agriculture.Recently,the United Nations launched the Sustainable Development Goals(SDGs),and the Nineteenth National People’s Congress has delivered a national strategy for sustainable development in China—realizing green development.The overall objective of Agriculture Green Development(AGD)is to coordinate'green'with'development'to realize the transformation of current agriculture with high resource consumption and high environmental costs into a green agriculture and countryside with high productivity,high resource use efficiency and low environmental impact.This is a formidable task,requiring joint efforts of government,farmers,industry,educators and researchers.The innovative concept for AGD will focus on reconstructing the whole crop-animal production and food production-consumption system,with the emphasis on high thresholds for environmental standards and food quality as well as enhanced human well-being.This paper addresses the significance,challenges,framework,pathways and potential solutions for realizing AGD in China,and highlights the potential changes that will lead to a more sustainable agriculture in the future.Proposals include interdisciplinary innovations,whole food chain improvement and regional solutions.The implementation of AGD in China will provide important implications for the countries in developmental transition,and contribute to global sustainable development.Jianbo SHEN Qichao ZHU Xiaoqiang JIAO Hao YING Hongliang WANG Xin WEN Wen XU Tingyu LI Wenfeng CONG Xuejun LIU Yong HOU Zhenling CUI Oene OENEMA William JDAVIES Fusuo ZHANG 2020Frontiers of Agricultural Science and Engineering2020,7,1:18
2Performance and mechanism of Cr(Ⅵ)removal by zero-valent iron loaded onto expanded graphite显示文摘Zero-valent iron(ZⅥ) was loaded on expanded graphite(EG) to produce a composite material(EG-ZⅥ) for efficient removal of hexavalent chromium(Cr(Ⅵ)). EG and EG-ZⅥ were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM),Fourier-transform infrared(FTIR) spectroscopy and Brunauer–Emmett–Teller(BET) analysis. EG-ZⅥ had a high specific surface area and contained sub-micron sized particles of zero-valent iron. Batch experiments were employed to evaluate the Cr(Ⅵ) removal performance. The results showed that the Cr(Ⅵ) removal rate was 98.80% for EG-ZⅥ,which was higher than that for both EG(10.00%) and ZⅥ(29.80%). Furthermore, the removal rate of Cr(Ⅵ) by EG-ZⅥ showed little dependence on solution p H within a p H range of 1–9.Even at pH 11, a Cr(Ⅵ) removal rate of 62.44% was obtained after reaction for 1 hr. EG-ZⅥ could enhance the removal of Cr(Ⅵ) via chemical reduction and physical adsorption,respectively. X-ray photoelectron spectroscopy(XPS) was used to analyze the mechanisms of Cr(Ⅵ) removal, which indicated that the ZⅥ loaded on the surface was oxidized, and the removed Cr(Ⅵ) was immobilized via the formation of Cr(III) hydroxide and Cr(III)–Fe(III)hydroxide/oxyhydroxide on the surface of EG-ZⅥ.Congbin Xu Wenjie Yang Weijiang Liu Hongliang Sun Chunlei Jiao Ai-jun Lin 2018Journal of Environmental Sciences2018,30,5:10
3Investigation of octupole effects in superheavy nuclei with improved potential-energy-surface calculations显示文摘It has been found that high-order deformation (e.g.β6) can have important effects on the structures of superheavy nuclei. In the present work, we investigate octupole deformation effects on superheavy nuclei with an improved potential-energy-surface (PES) calculation by including reflection-asymmetric deformations in a space of (β2 ,β3 ,β4 , β5). The calculations give various deformations including highly deformed (β2 ≈ 0.4) and superdeformed (β2 ≈ 0.7) shapes. The octupole-deformation degree of freedom mainly affects the fission barrier beyond the second minimum of PES.WANG HuaLei LIU HongLiang XU FuRong JIAO ChangFeng 2012Chinese Science Bulletin2012,57,15:7
4Neuronal-like differentiation of single versus multiple treatments with human amnion-derived mesenchymal stem cells induced by basic fibroblast growth factor显示文摘<正>BACKGROUND:Cultures from multiple portions of umbilical cord blood mesenchymal stem cells have been shown to undergo more rapid proliferation and attachment than single portions. OBJECTIVE:To observe growth of basic fibroblast growth factor(bFGF)-induced cultures of human amnion-derived mesenchymal stem cells(AMSCs) and differentiation into neuronal-like cells. DESIGN,TIME AND SETTING:Comparative observation.The study was performed at the Laboratory of Microbiology and Immunology,Basic Medical School of Zhengzhou University from January to May 2008. METHODS:Amnia from full-term,uterine-incision delivery were donated by 12 healthy women. AMSCs were obtained by cell separation and culture techniques,and were passaged and induced by bFGF.From the third passage,a total of 1 mLAMSCs,at a density of 1.0×10~4/mL,was separately harvested from six samples,which served as group A.A total of 1 mLAMSCs,at a density of 1.0×10~4/mL,was harvested separately from the remaining six samples,which served as group B.A total of 0.5 mL from the six samples of group A and 0.5 mL from the six samples of group B were combined to form group C. MAIN OUTCOME MEASURES:Differences in cell quantity among the three groups were compared by cell quantification and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) analysis.Expression of a glial cell marker,neuron-specific enolase,and nestin was detected in the three groups by immunocytochemistry. RESULTS:Cell quantification and MTT analysis of live cells,as well as AMSC absorbance,were significantly greater in group C compared with groups A and B at 18 days of culture(P<0.05),and no significant difference was observed between groups A and B.Glial fibrillary acidic protein, neuron-specific enolase,and nestin were expressed in all groups following bFGF induction. CONCLUSION:Mixed AMSC cultures promoted proliferation,and bFGF-induced AMSCs differentiated into neuronal-like cells.Hongliang Jiao Fangxia Guan Xiang Hu Jianbin Li Hong Shan Wei Li Jun Li Ying Du Bo Yang Yunfan Zhou 2009Neural Regeneration Research2009,4,9:3

6Highly efficient flexible perovskite solar cells with vacuum-assisted low-temperature annealed SnO2 electron transport layer显示文摘The demand for lightweight, flexible, and high-performance portable power sources urgently requires high-efficiency and stable flexible solar cells. In the case of perovskite solar cells(PSCs), most of the common electron transport layer(ETL) needs to be annealed for improving the optoelectronic properties,while conventional flexible substrates could barely stand the high temperature. Herein, a vacuumassisted annealing SnO_(2) ETL at low temperature(100℃) is utilized in flexible PSCs and achieved high efficiency of 20.14%. Meanwhile, the open-circuit voltage(V_(oc)) increases from 1.07 V to 1.14 V. The flexible PSCs also show robust bending stability with 86.8% of the initial efficiency is retained after 1000 bending cycles at a bending radius of 5 mm. X-ray photoelectron spectroscopy(XPS), atomic force microscopy(AFM), and contact angle measurements show that the density of oxygen vacancies, the surface roughness of the SnO_(2) layer, and film hydrophobicity are significantly increased, respectively. These improvements could be due to the oxygen-deficient environment in a vacuum chamber, and the rapid evaporation of solvents. The proposed vacuum-assisted low-temperature annealing method not only improves the efficiency of flexible PSCs but is also compatible and promising in the large-scale commercialization of flexible PSCs.Xiaoguo Li Zejiao Shi Fatemeh Behrouznejad Mohammad Hatamvand Xin Zhang Yaxin Wang Fengcai Liu Haoliang Wang Kai Liu Hongliang Dong Farhan Mudasar Jiao Wang Anran Yu Yiqiang Zhan 2022Journal of Energy Chemistry2022,31,4:1
7A Review of the Engineering Role of Burrowing Animals: Implication of Chinese Pangolin as an Ecosystem Engineer显示文摘Ecosystem engineers are organisms that alter the distribution of resources in the environment by creating,modifying,maintaining and/or destroying the habitat.They can affect the structure and function of the whole ecosystem furthermore.Burrowing engineers are an important group in ecosystem engineers as they play a critical role in soil translocation and habitat creation in various types of environment.However,few researchers have systematically summarized and analyzed the studies of burrowing engineers.We reviewing the existing ecological studies of burrowing engineer about their interaction with habitat through five directions:(1)soil turnover;(2)changing soil physicochemical properties;(3)changing plant community structure;(4)providing limited resources for commensal animals;and/or(5)affecting animal communities.The Chinese pangolin(Manis pentadactyla)is a typical example of burrowing mammals,in part(5),we focus on the interspecific relationships among burrow commensal species of Chinese pangolin.The engineering effects vary with environmental gradient,literature indicates that burrowing engineer play a stronger role in habitat transformation in the tropical and subtropical areas.The most common experiment method is comparative measurements(include different spatial and temporal scale),manipulative experiment is relatively few.We found that most of the engineering effects had positive feedback to the local ecosystem,increased plant abundance and resilience,increased biodiversity and consequently improved ecosystem functioning.With the global background of dramatic climate change and biodiversity loss in recent decades,we recommend future studies should improving knowledge of long-term engineering effects on population scale and landscape scale,exploring ecological cascades through trophic and engineering pathways,to better understand the attribute of the burrowing behavior of engineers to restore ecosystems and habitat creation.The review is presented as an aid to systematically expound the engineering effect of burrowing animals in the ecosystem,and provided new ideas and advice for planning and implementing conservation management.Song Sun Hongliang Dou Shichao Wei Yani Fang Zexu Long Jiao Wang Fuyu An Jinqian Xu Tingting Xue Huangjie Qiu Yan Hua Guangshun Jiang 2021Journal of Zoological Research2021,3,3:0
8Emerging roles and potential clinical applications of translatable circular RNAs in cancer and other human diseases显示文摘Circular RNAs (circRNAs) are a special class of single-stranded RNA molecules with covalently closed loops widely expressed in eukaryotic organisms. CircRNAs have long been considered to play important roles in various physiological and pathological processes as non-coding RNAs. However, circRNAs have recently garnered considerable attention due to their ability to be translated into peptides/proteins via internal ribosome entry site- or N6-methyladenosine-mediated pathways or rolling translation mechanisms. Furthermore, dysregulation of translatable circRNAs and their encoded proteins has been associated with developing and progressing diseases such as cancer. This review aims to summarize the driving mechanisms of circRNA translation and the available strategies in circRNA translation research. The main focus is on the emerging biological functions of translatable circRNAs, their regulatory mechanisms, and potential clinical applications in human diseases to provide new perspectives on disease diagnosis, prognosis, and targeted therapy.Hongliang Liu Wenjing Hao Jiao Yang Yuliang Zhang Xinfang Wang Chunming Zhang 2023Genes & Diseases2023,10,5:0
