2Ca(NO3)2 canopy spraying during physiological fruit drop period has a better influence on the tree character and fruit quality of Newhall navel orange(Citrus sinensis Osbeck)显示文摘This study aimed to provide a theoretical basis for adopting suitable cultivation measures to tackle calcium(Ca) deficiency in citrus leaves. The Newhall navel orange(Citrus sinensis Osbeck) canopy was sprayed with 20.0 mmol L^(-1) of Ca(NO_3)_2 during physiological fruit drop period, fruit expanding period, and fruit maturing period on 30, 90, and 210 days after full bloom(DAFB), respectively, and its effects on leaf gas exchange parameters and leaf mineral nutrition and fruit quality were analyzed. The results showed that:(1) The photosynthetic rate(ACO_2) at 9:00 a.m. and 16:00 p.m. of fruit expanding period with 30 and 90 DAFB Ca(NO_3)_2 treatments slightly or significantly improved mainly by decreasing stomatal limitation and nonstomatal limitation, respectively.(2) Compared with control(CK), the Ca concentration in leaves with 30, 90, and 240 DAFB Ca(NO_3)_2 treatments increased by 127.16, 97.53, and 33.33%, respectively, and the leaf magnesium concentration also increased by more than 32.26%. However, Ca(NO_3)_2 canopy spraying on 30 DAFB significantly reduced the leaf potassium concentration, by 22.14% compared with CK.(3) Ca(NO_3)_2 canopy spraying on 30 DAFB decreased the second fruit drop rate by 30.55% and increased the weight per fruit by 25.04%, thus resulting in a significant increase in citrus yield.(4) Spraying Ca(NO3) on 30 DAFB mainly affected the metabolism of titratable acid(TA) to improve the maturity of citrus fruits. Whilst it improved the external quality and the coloring of citrus fruit significantly. Therefore, Ca(NO_3)_2 canopy spraying during physiological fruit drop period has a better influence on the tree character and fruit quality of Newhall navel orange(Citrus sinensis Osbeck).ZHENG Yong-qiang YANG Qiong JIA Xue-mei LIU Yan-mei HE Shao-lan DENG Lie XIE Rang-jin YI Shi-lai Lu Qiang 2017Journal of Integrative Agriculture2017,16,7:3
3A review of processing of Cu/C base plate composites for interfacial control and improved properties显示文摘The increase in both power and packing densities in power electronic devices has led to an increase in the market demand for effective heat-dissipating materials with a high thermal conductivity and thermal expansion coefficient compatible with chip materials while still ensuring the reliability of the power modules.Metal matrix composites,especially copper matrix composites,containing carbon fibers,carbon nanofibers,or diamond are considered very promising as the next generation of thermalmanagement materials in power electronic packages.These composites exhibit enhanced thermal properties,as compared to pure copper,combined with lower density.This paper presents powder metallurgy and hot uniaxial pressing fabrication techniques for copper/carbon composite materials which promise to be efficient heat-dissipation materials for power electronic modules.Thermal analyses clearly indicate that interfacial treatments are required in these composites to achieve high thermal and thermomechanical properties.Control of interfaces(through a novel reinforcement surface treatment,the addition of a carbide-forming element inside the copper powders,and processing methods),when selected carefully and processed properly,will form the right chemical/mechanical bonding between copper and carbon,enhancing all of the desired thermal and thermomechanical properties while minimizing the deleterious effects.This paper outlines a variety of methods and interfacial materials that achieve these goals.Jean-François Silvain Jean-Marc Heintz Amélie Veillere Loic Constantin Yong Feng Lu 2020International Journal of Extreme Manufacturing2020,2,1:2
4Serum Calcium Level is Associated with Brachial-ankle Pulse Wave Velocity in Middle-aged and Elderly Chinese显示文摘Objective To study the relation between serum calcium level and elevated BaPWV in Chinese subjects.Methods The relation between serum calcium level and elevated BaPWV was studied in 9 615subjects.The mean value of left and right BaPWV was analyzed.BaPWV was defined as high when it was?1 752.5 cm/s(the upper quartile)either side.Results The BaPWV and its elevated percentage progressively increased across the quartiles of the serum calcium level(P<0.05).The prevalence of elevated BaPWV was significantly higher in subjects of the second,third and highest quartiles than in those of the lowest quartile(26.9%,28.4%,and 33.2%vs23.7%,P=0.0116,P=0.0004,and P<0.0001).Logistic regression analysis revealed that the risk of elevated BaPWV was 1.32-fold higher in subjects of the highest quartile than in those of the lowest quartile(OR=1.32,95%CI:1.08-1.60).Conclusion The elevated serum calcium level is related to an elevated BaPWV and a higher risk of arterial stiffness,independent of conventional risk factors,in middle-aged and elderly Chinese subjects.DENG Xin Ru ZHANG Yin Fei WANG Tian Ge XU Bai Hui SUN Ji Chao ZHAO Lie Bin XU Min CHEN Yu Hong WANG Wei Qing BI Yu Fang LU Jie Li 2014Biomedical and Environmental Sciences2014,27,8:2

6An Organic Solvent-free Approach towards PDI/Carbon Cloth Composites as Flexible Lithium Ion Battery Cathodes显示文摘An acidic solution based method towards flexible lithium ion battery(LIB)cathodes is developed in this work with perylene diimide(PDI)as the electroactive component and carbon cloth(CC)as the current collector.In this approach,PDI is firstly dispersed in concentrated sulfuric acid(H2S04)and then deposited on CC substrate after the dilution of H2S04,which provides an organic solvent-free strategy to construct integrated LIB cathodes.The acdic solution based fabrication process also allows the facile adjusting of loading amounts of PDI in the cathodes,which can effectively influence the battery performances of the PDI/CC cathodes.As the result,the acidic solution processed PDI/CC cathode can deliver a high specific capacity of-36 mAh·g^-1 at the current density of 50 mA·g^-1 in both half cell with lithium foil as anode and full cell with pre-lithiated CC as anode.In both types of the batteries,the PDI/CC cathodes show good cycling stabilities by retaining^84%of the initial capacities after 300 charge-discharge cycles at 500 mA·g^-1.Additionally,the excellent mechanical stability of the PDI/CC cathode enables the LIBs in pouch cell to maintain the electrochemical performances under various bending states,demonstrating their potentials for flexible LIBs.Dong-Qing Wu Deng Lu Peng Yang Lie Ma Biao Jiang Xin Xi Fan-Cheng Meng Wen-Bei Zhang Fan Zhang Qian-Qian Zhong Rui-Li Liu 2020Chinese Journal of Polymer Science2020,38,5:1
