1Performance and recent improvement in microbial fuel cells for simultaneous carbon and nitrogen removal: A review显示文摘Microbial fuel cells(MFCs) have become a promising technology for wastewater treatment accompanying electricity generation. Carbon and nitrogen removal can be achieved by utilizing the electron transfer between the anode and cathode in an MFC. However,large-scale power production and high removal efficiency must be achieved at a low cost to make MFCs practical and economically competitive in the future. This article reviews the principles, feasibility and bottlenecks of MFCs for simultaneous carbon and nitrogen removal, the recent advances and prospective strategies for performance improvement, as well as the involved microbes and electron transfer mechanisms.Haishu Sun Shengjun Xu Guoqiang Zhuang Xuliang Zhuang 2016Journal of Environmental Sciences2016,28,1:10
2声波激励的超小型纳机电系统磁电天线显示文摘当前的小型天线依赖于电磁波的谐振,因此天线的尺寸与电磁波波长相关。典型的天线尺寸大于波长的1/10,而进一步缩小天线尺寸在近十年来都是一个公开的挑战。介绍一种通过悬浮铁氧/压电薄膜异质结构的声波激励纳机械磁电天线。这种磁电天线通过其在声波谐振频率处的磁电效应接收和发射电磁波。磁电天线中的体声波激发铁磁薄膜的磁化振荡,产生电磁波的辐射;反之,天线感应电磁波的磁场,得到压电电压输出。这种磁电天线(尺寸仅为波长的千分之一)比现有小型天线的尺寸小1到2个数量级,但性能却没有降低,在便携式无线通信系统中具有很大的应用潜力。Tianxiang Nan Hwaider Lin Yuan Gao Alexei Matyushov Guoliang Yu Huaihao Chen Neville Sun Shengjun Wei Zhiguang Wang Menghui Li Xinjun Wang Amine Belkessam Rongdi Guo Brian Chen James Zhou Zhenyun Qian Yu Hui Matteo Rinaldi Michael E.McConney BrANDon M.Howe Zhongqiang Hu John G.Jones Gail J.Brown Nian Xiang Sun 张建强(翻译) 陈鼎鼎(审校) 2017通信对抗2017,36,4:8
3Benzoate anions-intercalated NiFe-layered double hydroxide nanosheet array with enhanced stability for electrochemical seawater oxidation显示文摘Seawater electrolysis is an extremely attractive approach for harvesting clean hydrogen energy,but detrimental chlorine species(i.e.,chloride and hypochlorite)cause severe corrosion at the anode.Here,we report our recent finding that benzoate anions-intercalated NiFe-layered double hydroxide nanosheet on carbon cloth(BZ-NiFe-LDH/CC)behaves as a highly efficient and durable monolithic catalyst for alkaline seawater oxidation,affords enlarged interlayer spacing of LDH,inhibits chlorine(electro)chemistry,and alleviates local pH drop of the electrode.It only needs an overpotential of 320 mV to reach a current density of 500 mA·cm^(−2)in 1 M KOH.In contrast to the fast activity decay of NiFe-LDH/CC counterpart during long-term electrolysis,BZ-NiFe-LDH/CC achieves stable 100-h electrolysis at an industrial-level current density of 500 mA·cm^(−2)in alkaline seawater.Operando Raman spectroscopy studies further identify structural changes of disorderedδ(NiIII-O)during the seawater oxidation process.Longcheng Zhang Jie Liang Luchao Yue Kai Dong Jun Li Donglin Zhao Zerong Li Shengjun Sun Yongsong Luo Qian Liu Guanwei Cui Abdulmohsen Ali Alshehri Xiaodong Guo Xuping Sun 2022Nano Research Energy2022,1,3:6
4Proteasome inhibition suppresses Th17 cell generation and ameliorates autoimmune development in experimental Sjögren’s syndrome显示文摘Immunoproteasome activation in immune cells is involved in the modulation of immune responses.Increasing evidence indicates that proteasome inhibitors show beneficial effects in treating autoimmune diseases,but it remains unclear whether proteasome inhibition is an effective approach for suppressing autoimmune development in Sjögren’s syndrome(SS).Our previous work has demonstrated a critical role for Th17 cells in the development of experimental SS(ESS)in mice.In this study,we detected high levels of low-molecular-weight protein 7(LMP7),a key subunit of the immunoproteasome,in Th17 cells from ESS mice.Moreover,treatment with bortezomib(BTZ),a proteasome inhibitor,markedly suppressed Th17 differentiation in both murine and human naive T cells in culture.Furthermore,ESS mice treated with BTZ displayed significantly higher saliva flow rates and a reduction in tissue destruction in the salivary glands compared with vehicle-treated ESS mice.Notably,BTZ-treated ESS mice showed markedly decreased Th17 cells,germinal center B cells and plasma cells in the peripheral lymphoid organs.In addition,adoptively transferred wild type naive CD4+T cells rapidly differentiated into Th17 cells and induced salivary dysfunction in IL-17-deficient mice immunized for ESS induction.However,BTZ treatment profoundly suppressed the donor T-cell-derived Th17 response and ameliorated the reduction in salivary secretion in IL-17-deficient recipient mice.Taken together,our findings demonstrate that proteasome inhibition can effectively ameliorate ESS by suppressing the Th17 response,which may contribute to the development of a novel therapeutic strategy for the treatment of SS.Fan Xiao Xiang Lin Jie Tian Xiaohui Wang Qian Chen Ke Rui Jie Ma Shengjun Wang Qingwen Wang Xiaoqi Wang Dongzhou Liu Lingyun Sun Liwei Lu 2017Cellular & Molecular Immunology2017,14,11:6
5Ecto-mesenchymal stem cells: a new player for immune regulation and cell therapy显示文摘Extensive studies have demonstrated that mesenchymal stem cells(MSCs)are multipotent mesoderm-derived stromal cells that can differentiate into a variety of cell types,including adipocytes,osteoblasts,chondrocytes,myocytes and neuronal cells.1 MSCs are found in numerous organs and tissues,including bone marrow,heart,lung,muscle,peripheral blood,adipose tissue,cartilage,synovium,dental pulp,tonsil,umbilical cord,placenta,thymus and olfactory mucosa.1 MSCs have been shown to possess potent immunosuppressive functions and tissue repair capacities,which have facilitated the clinical applications of MSCs in treating a diverse range of disorders involving angiogenesis and fibrosis,including rheumatic diseases and graft-versus-host diseases.2,3 Here,we provide a brief commentary on newly emerging evidence of the immunoregulatory function and potential application of ecto-mesenchymal stem cells.Ke Rui Xiang Lin Jie Tian Xiaohui Wang Lingyun Sun Xiaoping Hong Dongzhou Liu Shengjun Wang Liwei Lu 2018Cellular & Molecular Immunology2018,15,1:4
6Pharmacological Activation of RXR-a Promotes Hematoma Absorption via a PPAR-y-dependent Pathway After Intracerebral Hemorrhage显示文摘Endogenously eliminating the hematoma is a favorable strategy in addressing intracerebral hemorrhage(ICH).This study sought to determine the role of retinoid X receptor-ot(RXR-a)in the context of hematoma absorption after ICH.Our results showed that pharmacologically activating RXR-a with bexarotene significantly accelerated hematoma clearance and alleviated neurological dysfunction after ICH.RXR-ot was expressed in microglia/macro-phages,neurons,and astrocytes.Mechanistically,bexarotene promoted the nuclear translocation of RXR-a and PPAR-y,as well as reducing neuroinflammation by modulating microglia/macrophage reprograming from the Ml into the M2 phenotype.Furthermore,all the beneficial effects of RXR-a in ICH were reversed by the PPAR-y inhibitor GW9662.In conclusion,the pharmacological activation of RXR-a confers robust neuroprotection against ICH by accelerating hematoma clearance and repolarizing microglia/macrophages towards the M2 phenotype through PPAR-y-related mechanisms.Our data support the notion that RXR-ot might be a promising therapeutic target for ICH.Chaoran Xu Huaijun Chen Shengjun Zhou Chenjun Sun Xiaolong Xia Yucong Peng Jianfeng Zhuang Xiongjie Fu Hanhai Zeng Hang Zhou Yang Cao Qian Yu Yin Li Libin Hu Guoyang Zhou Feng Yan Gao Chen Jianru Li 2021Neuroscience Bulletin2021,37,10:4
7Tranexamic acid for acute intracerebral haemorrhage growth based on imaging assessment (TRAIGE): a multicentre, randomised, placebo- controlled trial显示文摘Background Studies show tranexamic acid can reduce the risk of death and early neurological deterioration after intracranial haemorrhage.We aimed to assess whether tranexamic acid reduces haematoma expansion and improves outcome in intracerebral haemorrhage patients susceptible to haemorrhage expansion.Methods We did a prospective,double-blind,randomised,placebo-controlled trial at 10 stroke centres in China.Acute supratentorial intracerebral haemorrhage patients were eligible if they had indication of haemorrhage expansion on admission imaging(eg,spot sign,black hole sign or blend sign),and were treatable within 8 hours of symptom onset.Patients were randomly assigned(1:1)to receive either tranexamic acid or a matching placebo.The primary outcome was intracerebral haematoma growth(>33% relative or>6 mL absolute)at 24 hours.Clinical outcomes were assessed at 90 days.Results Of the 171 included patients,124(72.5%)were male,and the mean age was 55.9±11.6 years.89 patients received tranexamic acid and 82 received placebo.The primary outcome did not differ significantly between the groups:36(40.4%)patients in the tranexamic acid group and 34(41.5%)patients in the placebo group had intracranial haemorrhage growth(OR 0.96,95% CI 0.52 to 1.77,p=0.89).The proportion of death was lower in the tranexamic acid treatment group than placebo group(8.1%vs 10.0%),but there were no significant differences in secondary outcomes including absolute intracranial haemorrhage growth,death and dependency.Conclusions Among patients susceptible to haemorrhage expansion treated within 8 hours of stroke onset,tranexamic acid did not significantly prevent intracerebral haemorrhage growth.Larger studies are needed to assess safety and efficacy of tranexamic acid in intracerebral haemorrhage patients.Jingyi Liu Ximing Nie Hongqiu Gu Qi Zhou Haixin Sun Ying Tan Dacheng Liu Lina Zheng Jiahui Zhao Yan Wang Yibin Cao Haomeng Zhu Yunpeng Zhang Lijin Yi Yuehua Pu Miao Wen Zhonghua Yang Shengjun Sun Wenzhi Wang Xingquan Zhao Liping Liu Yongjun Wang 2021Stroke & Vascular Neurology2021,6,2:3
8Super Na^(+)Half/Full Batteries and Ultrafast Na+Diffusion Kinetics of Cobalt-Nickel Selenide from Assembling Co_(0.5)Ni_(0.5)Se_(2)@NC Nanosheets into Cross-Stacked Architecture显示文摘Explorati on of adva need an ode materials for sodium-i on batteries(SIBs)is still a big challe nge due to the large radius of sodium.In this work,the hierarchical architectures assembled from N-doped carbon-coated Co_(0.5)Ni_(0.5)Se_(2)(Co_(0.5)Ni_(0.5)Se_(2)@NC)nanoparticles encapsulated into cross-stacked nano sheets have been successfully prepared from the cobalt-nickel bin ary-metal organic frameworks(CoNi-MOF)by two steps of the solid-state sele nizati on and carb on coating processes.Imports ntly,the resulta nt hierarchical Co0.5Nio:5Se2@NC architecture can achieve a satisfactory electrochemical performance,maintaining a high-rate capacity of 330 mA-h-g^(-1)1 at 3 A·g^(-1) and a stable cyclability of 100 cycles without obvious capacity decay at 0.2 A·g^(-1).The design of distinct superstructure can not only be applied to other electrode materials but also boost the forward development of energy storage systems.Zhiyong Li Zilin Peng Rui Sun Zhaoxia Qin Xinlong Liu Caihong Wang Haosen Fan Shengjun Lu 2021Chinese Journal of Chemistry2021,39,9:3
9Haemostatic therapy in spontaneous intracerebral haemorrhage patients with high-risk of haematoma expansion by CT marker: a systematic review and meta- analysis of randomised trials显示文摘Background and purpose Current randomised controlled trials(RCTs)showed an uncertain benefit of haemostatic therapy on preventing haematoma expansion and improving the outcome in patients with intracerebral haemorrhage(ICH).This meta-analysis aims to systematically evaluate the effect of haemostatic agents on the prevention of haemorrhage growth in patients with high-risk spontaneous ICH predicted by CT signs in RCTs.Methods A comprehensive search of PubMed,EMBASE and Cochrane library from 1 January 2005 to 30 June 2021 was conducted.RCTs that compared haemostatic agents with placebo for the treatment of spontaneous patients with ICH with high-risk haemorrhage growth were included.The primary endpoint was haematoma expansion at 24 hours.Other major endpoints of interest included 90-day functional outcome and mortality.Results The meta-analysis included four RCTs that randomised 2666 patients with ICH with high-risk haemorrhage growth.Haemostatic therapy reduced the rate of haematoma expansion at a marginally statistically significant level when compared with placebo(OR 0.84;95% CI 0.70 to 1.00;p=0.051).Subgroup analysis for patients with black hole sign on CT revealed a significant reduction of haematoma expansion with haemostatic therapy(OR 0.61;95% CI 0.39 to 0.94;p=0.03).However,both the primary analysis and subgroup analyses showed that haemostatic therapy could not reduce the rate of poor functional outcome(modified Rankin Scale>3)or death.Conclusions Haemostatic therapy showed a marginally significant benefit in reducing early haematoma expansion in patients with high-risk spontaneous ICH predicted by markers on CT scan.However,no significant improvement in functional outcome or reduction of mortality was observed.Ximing Nie Jingyi Liu Dacheng Liu Qi Zhou Wanying Duan Yuehua Pu Zhonghua Yang Miao Wen Haixin Sun Wenzhi Wang Shengjun Sun Hongqiu Gu Liping Liu 2021Stroke & Vascular Neurology2021,6,2:2
10N, O-doped carbon foam as metal-free electrocatalyst for efficient hydrogen production from seawater显示文摘Seawater electrolysis is the most promising technology for large scale hydrogen production due to the abundance and low cost of seawater in nature.However,compared with the traditional freshwater electrolysis,the issues of electrode poisoning and corrosion will occur during the seawater electrolysis process,and active and stable electrocatalysts for the hydrogen evolution reaction(HER)are thus highly desired.In this work,N,O-doped carbon foam in-situ derived from commercial melamine foam is proposed as a high-active metal-free HER electrocatalyst for seawater splitting.In acidic seawater,our catalyst shows high hydrogen generation performance with small overpotential of 161 mV at 10 mA·cm^(−2),a low Tafel slop of 97.5 mV·dec^(−1),and outstanding stability.Qian Liu Shengjun Sun Longcheng Zhang Yongsong Luo Qin Yang Kai Dong Xiaodong Fang Dongdong Zheng Abdulmohsen Ali Alshehri Xuping Sun 2022Nano Research2022,15,10:2

12Mechanism of sea ice formation based on comprehensive observation data in Liaodong Bay, China显示文摘Sea ice disaster is one of the principal natural hazards that affect some coastal areas of China,and the formation of ice cover in a wave field has important characteristics.However,analysis of the mechanism in which waves affect the thermodynamic process of sea ice is lacking,and the influence of waves is not taken into consideration in numerical models of sea ice,largely because of a lack of simultaneous observations of waves and sea ice.Using observational data of the sea ice cycle in the coastal waters of Liaodong Bay(China),we analyzed the characteristics of hydrology,meteorology,and sea ice thickness during the formation of sea ice,and explored the changes in the interrelationships among heat fluxes,waves,and sea ice under actual sea conditions.The results could provide a decision-making support as a reference to the establishment and improvement of China's early waming system to sea ice disasters,and the protection of ice drilling operations and production platform safety.SHI Yongfang YANG Yongzeng TENG Yong SUN Meng YUN Shengjun 2019Journal of Oceanology and Limnology2019,37,6:1
13Enhanced N_(2)-to-NH_(3)conversion efficiency on Cu3P nanoribbon electrocatalyst显示文摘Ambient electroreduction of nitrogen(N_(2))is considered as a green and feasible approach for ammonia(NH_(3))synthesis,which urgently demands for efficient electrocatalyst.Morphology has close relationship with catalytic activity of heterogeneous catalysts.Nanoribbon is attractive nanostructure,which possesses the flexibility of one-dimensional nanomaterials,the large surface area of two-dimensional nanomaterials,and lateral size confinement effects.In this work,Cu_(3)P nanoribbon is proposed as a highly efficient electrocatalyst for N_(2)-to-NH_(3)conversion under benign conditions.When measured in N_(2)-saturated 0.1 M HCl,such Cu_(3)P nanoribbon achieves high performance with an excellent Faradaic efficiency as high as 37.8%and a large yield of 18.9μg·h^(−1)·mgcat.−1 at−0.2 V.It also demonstrates outstanding stability in long-term electrolysis test at least for 45 h.Qian Liu Yiting Lin Shuang Gu Ziqiang Cheng Lisi Xie Shengjun Sun Longcheng Zhang Yongsong Luo Abdulmohsen Ali Alshehri Mohamed SHamdy Qingquan Kong Jiahong Wang Xuping Sun 2022Nano Research2022,15,8:1

18Whole-genome resequencing of the wheat A subgenome progenitor Triticum urartu provides insights into its demographic history and geographic adaptation显示文摘Triticum urartu is the progenitor of the A subgenome in tetraploid and hexaploid wheat.Uncovering the landscape of genetic variations in T.urartu will help us understand the evolutionary and polyploid characteristics of wheat.Here,we investigated the population genomics of T.urartu by genome-wide sequencing of 59 representative accessions collected around the world.A total of 42.2 million highquality single-nucleotide polymorphisms and 3 million insertions and deletions were obtained by mapping reads to the reference genome.The ancient T.urartu population experienced a significant reduction in effective population size(Ne)from3000000 to140000 and subsequently split into eastern Mediterranean coastal and Mesopotamian-Transcaucasian populations during the Younger Dryas period.A map of allelic drift paths displayed splits and mixtures between different geographic groups,and a strong genetic drift towards hexaploid wheat was also observed,indicating that the direct donor of the A subgenome originated from northwestern Syria.Genetic changes were revealed between the eastern Mediterranean coastal and Mesopotamian-Transcaucasian populations in genes orthologous to those regulating plant development and stress responses.A genome-wide association study identified two single-nucleotide polymorphisms in the exonic regions of the SEMI-DWARF 37 ortholog that corresponded to the different T.urartu ecotype groups.Our study provides novel insights into the origin and genetic legacy of the A subgenome in polyploid wheat and contributes a gene repertoire for genomicsenabled improvements in wheat breeding.Xin Wang Yafei Hu Weiming He Kang Yu Chi Zhang Yiwen Li Wenlong Yang Jiazhu Sun Xin Li Fengya Zheng Shengjun Zhou Lingrang Kong Hongqing Ling Shancen Zhao Dongcheng Liu Aimin Zhang 2022Plant Communications2022,3,5:1
19Electrochemical and Pseudocapacitive Analysis of Rod-Like MoO_(2)@MoSe_(2)@NC Heterostructures for High-Performance Lithium Ion Batteries显示文摘A micro-scale rod-like heterostructure derived from molybdenum-based metal organic framework(Mo-MOF)has been successfully prepared via subsequent annealing treatment,which assembled from N-doped carbon encapsulated MoSe_(2) nanosheets grown on the surface of MoO_(2) microrod(named as MoO_(2)@MoSe_(2)@NC).For this novel heterostructure,the MoO_(2) nanoparticles assembled into rod core not only serve as supporting substrate for facilitating the fast kinetics of Li+cations inside the electrode but also protect the MoSe_(2) structure from restacking in the charge/discharge process.Moreover,the outer-layered MoSe2 nanosheets enable the fast lithium ion movement owing to its large interlayer spacing.Moreover,this unique rod-like core-shell structure composite could further effectively alleviate the structural strains caused by large volume expansion during charge/discharge process,thus leading to stable electrochemical performance when evaluated as anode material for lithium ion batteries.Electrochemical testing exhibits that the MoO_(2)@MoSe_(2)@NC heterostructure presents highly reversible capacity of 468 mAh g^(-1)at 0.5 A g^(-1)and superior rate capability(318 mAh g^(-1)even at 5.0 A g^(-1)),which is attributed to the synergistic effect of N-doped carbon encapsulated MoSe2 nanosheets and MoO_(2) nanoparticles.Zhaoxia Qin Xinlong Liu Zhiyin Huang Rui Sun Zhiyong Li Haosen Fan Shengjun Lu 2021Acta Metallurgica Sinica(English Letters)2021,34,3:1
