5Thermal energy storage:Challenges and the role of particle technology显示文摘Thermal energy is at the heart of the whole energy chain providing a main linkage between the primary and secondary energy sources.Thermal energy storage(TES)has a pivotal role to play in the energy chain and hence in future low carbon economy.However,a competitive TES technology requires a number of scientific and technological challenges to be addressed including TES materials,TES components and devices,and integration of TES devices with energy networks and associated dynamic optimization.This paper provides a perspective of TES technology with a focus on TES materials challenges using molten salts based phase change materials for medium and high temperature applications.Two key challenges for the molten salt based TES materials are chemical incompatibility and low thermal conductivity.The use of composite materials provides an avenue to meeting the challenges.Such composite materials consist of a phase change material,a structural supporting material,and a thermal conductivity enhancement material.The properties of the supporting material could determine the dispersion of the thermal conductivity enhancement material in the salt.A right combination of the salt,the structural supporting material,and the thermal conductivity enhancement material could give a hierarchical structure that is able to encapsulate the molten salt and give a substantial enhancement in the thermal conductivity.Understanding of the structure-property relationships for the composite is essential for the formulation design and fabrication of the composite materials.Linking materials properties to the system level performance is recommended as a key future direction of research.Zhiwei Ge Yongliang Li Dacheng Li Ze Sun Yi Jin Chuanping Liu Chuan Li Guanghui Leng Yulong Ding 2014Particuology2014,12,4:20
6Relationship between Two Blood Stasis Syndromes and Inflammatory Factors in Patients with Acute Coronary Syndrome显示文摘Objective: To investigate the relationship between inflammatory factors and two Chinese medicine(CM) syndrome types of qi stagnation and blood stasis(QSBS) and qi deficiency and blood stasis(QDBS) in patients with acute coronary syndrome(ACS). Methods: Sixty subjects with ACS, whose pathogenesis changes belongs to qi disturbance blood stasis syndrome, were divided into 2 groups: 30 in the QSBS group and 30 in the QDBS group. The comparative analysis on them was carried out through comparing general information, coronary angiography and inflammatory factors including intracellular adhesion molecule-1(ICAM-1), chitinase-3-like protein 1(YKL-40) and lipoprotein-associated phospholipase A2(Lp-PLA2). Results: Compared with the QSBS group, Lp-PLA2 and YKL-40 levels in the QDBS group showed no-significant difference(P>0.05); ICAM-1 was significantly higher in the QDBS group than in the QSBS group in the pathological processes of qi disturbance and blood stasis syndrome of ACS(P<0.05). Conclusion: Inflammatory factor ICAM-1 may be an objective basis for syndrome typing of QSBS and QDBS, which provides a research direction for standardization research of CM syndrome types.MA Cai-yun LIU Jing-hua LIU Jian-xun SHI Da-zhuo XU Zhen-ye WANG Shao-ping JIA Min ZHAO FU-hai JIANG YUE-rong MA Qin PENG Hong-yu LU Yuan ZHENG Ze REN Feng-xue 2017Chinese Journal of Integrative Medicine2017,23,11:19
7Carbon carry capacity and carbon sequestration potential in China based on an integrated analysis of mature forest biomass显示文摘Forests play an important role in acting as a carbon sink of terrestrial ecosystem.Although global forests have huge carbon carrying capacity(CCC)and carbon sequestration potential(CSP),there were few quantification reports on Chinese forests.We collected and compiled a forest biomass dataset of China,a total of 5841 sites,based on forest inventory and literature search results.From the dataset we extracted 338 sites with forests aged over 80 years,a threshold for defining mature forest,to establish the mature forest biomass dataset.After analyzing the spatial pattern of the carbon density of Chinese mature forests and its controlling factors,we used carbon density of mature forests as the reference level,and conservatively estimated the CCC of the forests in China by interpolation methods of Regression Kriging,Inverse Distance Weighted and Partial Thin Plate Smoothing Spline.Combining with the sixth National Forest Resources Inventory,we also estimated the forest CSP.The results revealed positive relationships between carbon density of mature forests and temperature,precipitation and stand age,and the horizontal and elevational patterns of carbon density of mature forests can be well predicted by temperature and precipitation.The total CCC and CSP of the existing forests are 19.87 and 13.86 Pg C,respectively.Subtropical forests would have more CCC and CSP than other biomes.Consequently,relying on forests to uptake carbon by decreasing disturbance on forests would be an alternative approach for mitigating greenhouse gas concentration effects besides afforestation and reforestation.LIU Ying Chun YU Gui Rui WANG Qiu Feng ZHANG Yang Jian XU Ze Hong 2014Science China(Life Sciences)2014,57,12:15
8Generation of B Cell-Deficient Pigs by Highly Efficient CRISPR/Cas9-Mediated Gene Targeting显示文摘Generating B cell-deficient mutant is the first step to produce human antibody repertoires in large animal models. In this study, we applied the clustered regularly interspaced short palindromic repeat(CRISPR)/CRISPR-associated(Cas) system to target the JHregion of the pig Ig M heavy chain gene which is crucial for B cell development and differentiation. Transfection of Ig M-targeting Cas9 plasmid in primary porcine fetal fibroblasts(PFFs) enabled inducing gene knock out(KO) in up to 53.3% of colonies analyzed, a quarter of which harbored biallelic modification, which was much higher than that of the traditional homologous recombination(HR). With the aid of somatic cell nuclear transfer(SCNT) technology, three piglets with the biallelic Ig M heavy chain gene mutation were produced. The piglets showed no antibody-producing B cells which indicated that the biallelic mutation of the Ig M heavy chain gene effectively knocked out the function of the Ig M and resulted in a B cell-deficient phenotype. Our study suggests that the CRISPR/Cas9 system combined with SCNT technology is an efficient genome-editing approach in pigs.Fengjiao Chen Ying Wang Yilin Yuan Wei Zhang Zijian Ren Yong Jin Xiaorui Liu Qiang Xiong Qin Chen Manling Zhang Xiaokang Li Lihua Zhao Ze Li Zhaoqiang Wu Yanfei Zhang Feifei Hu Juan Huang Rongfeng Li Yifan Dai 2015Journal of Genetics and Genomics2015,42,8:15

10Synergistically Directed Assembly of Aromatic Stacks Based Metal-Organic Frameworks by Donor-Acceptor and Coordination Interactions显示文摘A synergistically directed assembly approach to distinctive metal-organic frameworks utilizing both donor-acceptor (D-A) interaction from aromatic systems and coordination interactions is presented.Based on such an approach,the coronene-tpt (tpt =2,4,6-tri(4-pyridyl)-1,3,5-triazine) stacks based coronene-MOF-1-4 have been successfully fabricated.Their structural discrepancies with coroneneabsent control products,1'-4',illustrate clearly the significance of coronene-tpt based D-A interactions in these architectures.All these coronene-MOFs contain varied coronene-tpt stacks as organic secondary building blocks (SBUs),which are closely interrelated with the coordination based framework structures.Moreover,porous coronene-MOF-1 and-2 exhibit high physicochemical stability and significant light hydrocarbons storage and separation performances.Xi Wang Ying Zhang Ze Chang Hui Huang Xiao-Ting Liu Jialiang Xu Xian-He Bu 2019Chinese Journal of Chemistry2019,37,9:11
11How Work Organization Affects the Prevalence of WMSDs: A Case-control Study显示文摘Objective In this study, we aimed at exploring the association between work-related musculoskeletal disorders(WMSDs) and work organization based on a case-control study. Methods A total of 1938 workers who claimed to suffer from WMSDs were selected from Beijing, Henan, Hubei, and the Guangdong province. The control group consisted of 2009 workers employed in similar industries without severe disease or musculoskeletal discomforts. We used a modified version of the questionnaire developed by the NMQ and the DMQ to investigate individual and work-related factors. Results A total of 13 variables(P<0.1) were selected by the chi-square test and finally, 7 variables entered into the equation, with 6 variables reaching statistical significance(P<0.05). The odds ratios(OR) of ‘work changing with season' and ‘sufficient rest time' did not reach 1(0.749 and 0.441, respectively). In addition, ‘sufficient rest time' seemed to be the stronger protective factor according to its higher standardized coefficient. And ‘repetitive work every minute', ‘constantly repetitive work'(every day), ‘shortage of site personnel', and ‘often switching shifts with others' seemed to be the risk factors. Conclusion Work organization may have comprehensive effects on the occurrence of WMSDs. This pattern of associations suggests that further investigation into the mechanism of how work organization affects the prevalence of WMSDs is required.LIU Lu CHEN Song Gen TANG Shi Chuan WANG Sheng HE Li Hua GUO Ze Hua LI Jing Yun YU Shan Fa WANG Zhong Xu 2015Biomedical and Environmental Sciences2015,28,9:11

15A novel HfNbTaTiV high-entropy alloy of superior mechanical properties designed on the principle of maximum lattice distortion显示文摘This paper reports a synergistic design of high-performance BCC high-entropy alloy based on the combined consideration of the principles of intrinsic ductility of elements,maximum atomic size difference for solid solution strengthening and the valence electron concentration criterion for ductility.The single-phase BCC HfNbTaTiV alloy thus designed exhibited a high compressive yield strength of 1350 MPa and a high compressive ductility of>45%at the room temperature.This represents a 50%increase in yield strength relative to a HfNbTaTiZr alloy.This is attributed to the maximized solid solution strengthening effect caused by lattice distortion,which is estimated to be 1094 MPa.The alloy was also able to retain 53%of its yield strength and 77%of its ductility at 700℃.These properties are superior to those of most refractory BCC high-entropy alloys reported in the literature.Zibing An Shengcheng Mao Yinong Liu Li Wang Hao Zhou Bin Gan Ze Zhang Xiaodong Han 2021Journal of Materials Science & Technology2021,,20:9
16Apolipoprotein E, amyloid-beta, and neuroinflammation in Alzheimer's disease显示文摘Alzheimer's disease(AD) is characterized by the accumulation and deposition of amyloid-beta(Aβ) peptides in the brain. Neuroinflammation occurs in the AD brain and plays a critical role in the neurodegenerative pathology. Particularly, Aβ evokes an inflammatory response that leads to synaptic dysfunction, neuronal death, and neurodegeneration. Apolipoprotein E(ApoE) proteins are involved in cholesterol transport, Aβ binding and clearance, and synaptic functions in the brain. The ApoE4 isoform is a key risk factor for AD, while the ApoE2 isoform has a neuroprotective effect. However, studies have reached different conclusions about the roles of the isoforms; some show that both ApoE3 and ApoE4 have anti-infl ammatory effects, while others show that ApoE4 causes a predisposition to inflammation or promotes an inflammatory response following lipopolysaccharide treatment. These discrepancies may result from the differences in models, cell types, experimental conditions, and inflammatory stimuli used. Further, little was known about the role of ApoE isoforms in the Aβ-induced inflammatory response and in the neuroinflammation of AD. Our recent work showed that ApoE isoforms differentially regulate and modify the Aβ-induced infl ammatory response in neural cells, with ApoE2 suppressing and ApoE4 promoting the response. In this article, we review the roles, mechanisms, and interrelations among Aβ, ApoE, and neuroinfl ammation in AD.Evan Dorey Nina Chang Qing Yan Liu Ze Yang Wandong Zhang 2014Neuroscience Bulletin2014,30,2:9

18Identification of biomarkers for hepatocellular carcinoma by semiquantitative immunocytochemistry显示文摘AIM:To investigate the expression of key biomarkers in hepatoma cell lines,tumor cells from patients’blood samples,and tumor tissues.METHODS:We performed the biomarker tests in two steps.First,cells plated on coverslips were used to assess biomarkers,and fluorescence intensities were calculated using the NIH Image J software.The measured values were analyzed using the SPSS19.0 software to make comparisons among eight cell lines.Second,eighty-four individual samples were used to assess the biomarkers’expression.Negative enrichment of the blood samples was performed,and karyocytes were isolated and dropped onto pretreated glass slides for further analysis by immunofluorescence staining.Fluorescence intensities were compared among hepatocellular carcinoma(HCC)patients,chronic HBV-infected patients,and healthy controls following methods similar to those used for cell lines.The relationships between the expression of biomarkers and clinical pathological parameters were analyzed by Spearman rank correlation tests.In addition,we studied the distinct biomarkers’expression with three-dimensional laser confocal microscopy reconstructions,and Kaplan-Meier survival analysis was performed to understand the clinical significance of these biomarkers.RESULTS:Microscopic examination and fluorescence intensity calculations indicated that cytokeratin 8/18/19(CK)expression was significantly higher in six of the seven HCC cell lines examined than in the control cells,and the expression levels of asialoglycoprotein receptor(ASGPR)and glypican-3(GPC3)were higher in all seven HCC cell lines than in the control.Cells obtained from HCC patients’blood samples also displayed significantly higher expression levels of ASGPR,GPC3,and CK than cells from chronic HBV-infected patients or healthy controls;these proteins may be valuable surface biomarkers for identifying HCC circulating tumor cells isolated and enriched from the blood samples.The stem cell-like and epithelial-mesenchymal transition-related biomarkers could be detected on the karyocyte slides.ASGPR and GPC3 were expressed at high levels,and thus three-dimensional reconstructions were used to observe their expression in detail.This analysis indicated that GPC3 was localized in the cytoplasm and membrane,but that ASGPR had a polar localization.Survival analyses showed that expression of GPC3 and ASGPR is associated with a patient’s overall survival(OS).CONCLUSION:ASGPR,GPC3,and CK may be valuable HCC biomarkers for CTC detection;the expression of ASGPR and GPC3 might be helpful for understanding patients’OS.Hong Mu Kai-Xuan Lin Hong Zhao Shu Xing Cong Li Fang Liu Hai-Zhen Lu Ze Zhang Yu-Lin Sun Xi-Yun Yan Jian-Qiang Cai Xiao-Hang Zhao 2014World Journal of Gastroenterology2014,20,19:8
19Effect of SiO_2/Na_2O mole ratio on the properties of foam geopolymers fabricated from circulating fluidized bed fly ash显示文摘Geopolymers are three-dimensional aluminosilicates formed in a short time at low temperature by geopolymerization. In this paper, alkali-activated foam geopolymers were fabricated from circulating fluidized bed fly ash(CFA), and the effect of SiO2/Na2O mole ratio(0.91–1.68) on their properties was studied. Geopolymerization products were characterized by mechanical testing, scanning electron microscopy(SEM), energy-dispersive X-ray spectroscopy(EDX), and X-ray diffraction(XRD). The results show that SiO2/Na2O mole ratio plays an important role in the mechanical and morphological characteristics of geopolymers. Foam samples prepared in 28 d with a SiO2/Na2O mole ratio of 1.42 exhibit the greatest compressive strength of 2.52 MPa. Morphological analysis reveals that these foam geopolymers appear the relatively optimized pore structure and distribution, which are beneficial to the structure stability. Moreover, a combination of the Si/Al atomic ratio ranging between 1.47 and 1.94 with the Na/Al atomic ratio of about 1 produces the samples with high strength.Ze Liu Ning-ning Shao Tian-yong Huang Jun-feng Qin Dong-min Wang Yu Yang 2014International Journal of Minerals,Metallurgy and Materials2014,21,6:8
20Impedance Modeling and Stability Analysis of PV Grid-connected Inverter Systems Considering Frequency Coupling显示文摘Impedance analysis is an effective method to analyze the oscillation issue associated with grid-connected photovoltaic systems.However,the existing impedance modeling of a gridconnected photovoltaic inverter usually only considers the effect of a single perturbation frequency,ignoring the coupling frequency response between the internal control loops of a grid-connected inverter,which severely affects the accuracy of the stability analysis.Hence,a method of impedance modeling and stability analysis for grid-connected photovoltaic inverters considering cross-coupling frequency is proposed in this paper.First,the generation mechanism of frequency coupling in gridconnected photovoltaic inverters,and the relationship between the coupling frequency and perturbation frequency are analyzed.Secondly,a sequence impedance model of grid-connected photovoltaic systems considering the coupling frequency is established by using the harmonic linearization method.The impact of DC bus voltage control strategy on frequency coupling characteristics of a grid-connected photovoltaic system is evaluated,and the impact of a coupling frequency term on system stability is quantitatively analyzed.Finally,the advantages of the proposed method are verified by several simulations.The results show that the proposed impedance model can accurately predict the potential resonance points of the system,and the coupling frequency characteristics will become much stronger with smaller DC bus capacitance or larger bandwidth of the DC bus controller.Shaojian Song Ze Wei Yuzhang Lin Bin Liu Hui Liu 2020CSEE Journal of Power and Energy Systems2020,6,2:8
