2Variation analyses of growth and wood properties of Larix olgensis clones in China显示文摘The growth traits(tree height, diameter at breast height, and stem straightness degree) and wood properties[wood density(WD), fiber length, fiber width, ash content(AC), lignin content, cellulose content, hemicellulose content(HEC), and holocellulose content] of 208 26-yearold Larix olgensis clones were analyzed. Except for WD and AC, there were significant differences(p \ 0.01) for all traits among clones. The phenotypic coefficient of variation and repeatability of all traits were 9.34–35.33%and 0.218–0.930, respectively. Tree height and diameter at breast height showed significant positive correlation;however, the correlation coefficients among growth characteristics and wood properties were mostly not significant.Ten clones(L70, L56, L82, L90, L59, L91, L61, L92, L86,and L64) were selected as excellent clones under a selection rate of 5%, using tree height, diameter at breast height,and stem straightness degree as evaluation indexes, providing genetic gains of 28.69, 17.96, and 0.67%, respectively. Ten clones(L88, L305, L59, L66, L253, L304,L277, L298, L248, and L293) were selected as excellent clones using wood properties as an evaluation index, with a selection rate of 5%, providing genetic gains in WD, fiber length, fiber width, cellulose content, and HEC of 4.14,3.64, 9.28, 6.77, and 9.61%, respectively. This study provides a theoretical basis for selecting excellent L. olgensis clones.Shaopeng Yin Zhenhai Xiao Guohui Zhao Xin Zhao Xiaoyang Sun Ying Zhang Fuwei Wang Shuchun Li Xiyang Zhao Guan-Zheng Qu 2017Journal of Forestry Research2017,28,4:6
3Hierarchical Porous RGO/PEDOT/PANI Hybrid for Planar/Linear Supercapacitor with Outstanding Flexibility and Stability显示文摘Many hybrid electrodes for supercapacitors(SCs)are a reckless combination without proper structural design that keeps them from fulfilling their potential.Herein,we design a reduced graphene oxide/poly(3,4-ethylenedioxythiophene)/polyaniline(RGO/PEDOT/PANI)hybrid with hierarchical and porous structure for high-performance SCs,where components fully harness their advantages,forming an interconnected and conductive framework with substantial reactive sites.Thus,this hybrid achieves a high capacitance of 535 F g^−1 along with good rate capability and cyclability.The planar SC based on this hybrid deliver an energy density of 26.89 Wh kg^−1 at a power density of 800 W kg^−1.The linear SC developed via modifying a cotton yarn with the hybrid exhibits good flexibility and structural stability,which operates normally after arbitrary deformations.This work provides a beneficial reference for developing SCs.Fuwei Liu Luoyuan Xie Li Wang Wei Chen Wei Wei Xian Chen Shaojuan Luo Lei Dong Qilin Dai Yang Huang Lei Wang 2020Nano-Micro Letters2020,12,2:5
4Synthesis of three-dimensionally ordered porous perovskite type LaMnO_3 for Al-air battery显示文摘LaMnO_3 catalysts with three-dimensionally ordered holes perovskite structure were prepared via closepacked SiO_2 template synthesized by Stober-Frink method. SEM, XRD and BET were employed to characterize the microstructure, phases and specific surface area. CV method was used to the oxygen electrode beha-vior of catalysts. Diameter of the holes was about 330 nm, corresponding to the size of SiO_2 template. Full-cell discharge tests were performed on aluminum-air battery fabricated by porous LaMnO_3.Results showed that the discharge performance of porous LaMnO_3 were 1.54 V, 1.42 V and 1.24 V respectively when the discharge currents were set at 5 mA/cm^2,10 mA/cm^2 and 20 mA/cm^2, respectively, which were higher than that of LaMnO_3 prepared by coprecipitation method(1.33 V, 1.09 V, 0.63 V, respectively).Fuwei Xiang Xiuhua Chen Jie Yu Wenhui Ma Yuping Li Ni Yang 2018Journal of Materials Science & Technology2018,34,9:3
5Experimental and Comparison Study on Two Solar Dish Systems with a High Concentration Ratio显示文摘Two high concentrating solar systems have been established with dish concentrator and plane-mirrors array concentrator.In the paper,the thermal performance has been experimentally studied with jet water cooling device and flat microchannel water-cooled device.The experimental results show that the maximum surface temperature difference of the dish concentrating system is greater than 20°C,while the plane-mirrors array system is lower than 4°C.It indicates that the plane-mirrors array concentrator has better uniformity.As the concentration ratio increases,the electrical efficiency of the concentrating photovoltaic system gradually decreases.When the concentration ratio is 200,the electrical efficiency of the photovoltaic system is 25%.The concentration ratio of 500 times or less is considered to be a suitable value,and then the electrical efficiency can still exceed 20%.It is found that the plane-mirrors array solar system is more suitable for the photovoltaic system than dish type system,which is only suitable for thermal power generation system.CHEN Haifei LI Guiqiang YANG Jie ZHANG Fuwei LIANG Ming JI Jie 2019Journal of Thermal Science2019,28,6:3
6Palladium-Catalyzed Tandem Carbonylative Aza-Wacker-Type Cyclization of Nucleophile Tethered Alkene to Access Fused N-Heterocycles显示文摘Although tandem reactions offer rapid access to structurally complex molecules in one-pot reaction,the selectivity issue needs to be addressed particularly when incompatible step reactions are involved.Herein,we report the selective synthesis of fused N-heterocycles from nucleophile-tethered alkenylamide and carbon monoxide via palladium(Pd)-catalyzed tandem carbonylative aza-Wacker-type cyclization.The electron-deficient nature of amide N—H and the intramolecular coordination of Pd with alkene accelerate the aminopalladation and effectively prevent the side oxidative carbonylation of diamine moiety to form urea.It is also found that the reported acyl Pd chloride intermediate may not be involved in this tandem cyclization.This work not only provides an efficient synthetic route to fused 1,4-diazepanones and 1,4-diazepanes but also inspires further development of tandem reactions for the diverse synthesis of heterocycles.Lijun Shi Mingshan Wen Fuwei Li 2021Chinese Journal of Chemistry2021,39,2:2

12Defective TiO_(2)-graphene heterostructures enabling in-situ electrocatalyst evolution for lithium-sulfur batteries显示文摘Lithium-sulfur (Li-S) batteries are considered as one of the promising next-generation energy storage systems because of their high energy density. While the low utilization of sulfur and sluggish reaction kinetics would lead to degradation of electrochemical performance and thus hinder the practical application of Li-S batteries. Herein, a double-shelled TiO_(2)-graphene heterostructure (H-TiO_(2)/rGO) with abundant oxygen vacancies (OVs) and highly exposed active plane as advanced host material in Li-S batteries is designed. This rational structure not only provides sufficient active sites and lower bandgap for lithium polysulfides (LiPSs), but also builds smooth adsorption-diffusion-conversion of LiPSs on catalyst, which greatly reduces interfacial energy barrier and promotes the utilization of sulfur through suppressing the devastating shuttling effect. Combining the synergetic merits of strong anchoring ability and catalyzing the of LiPSs, the electrode (S-TiO_(2)/rGO-1) exhibits superior rate performance and long lifespan (1000 cycles at 1C, 0.023% capacity loss per cycle) with high columbic efficiency. This work paves an alternative way to establish smooth adsorption-diffusion-conversion of polysulfides on catalyst in Li-S batteries and provides a new sight to understand catalyst design in energy storage devices.Yanqi Feng Hui Liu Yi Liu Fuwei Zhao Junqi Li Xuanmeng He 2021Journal of Energy Chemistry2021,30,11:1

15Hot Deformation Characteristics for a Nickel-base Superalloy GH742y显示文摘The hot deformation characteristics of as-cast nickel-base superalloy GH742y after hot isostatic pressing (HIP)(hereafter referred to as-cast alloy) have been investigated by hot compression tests in the temperature range of 1050 to 1140℃, strain rate range of 0.01 s-1 to 10 s-1 and strain range of 35% to 50% by means of Gleeble-3500 thermal mechanical simulator. The results show that the as-cast alloy exhibits the poor deformability,and shows wedge-shaped cracking beyond the strain of 35%. At strain rates less than 1.0 s-1, the stress-strain curves exhibit nearly steady-state behavior, while at strain rate of 10 s-1, a yield drop and serrated yielding occur. The activation energy values developed on the basis of the experimental data are divided into three domains. The first domain appears at lower strain rate (≤1.0 s-1) and lower temperature (≤1080℃), with the lowest mean value of activation energy about 261.4 kJ/mol. The second domain appears at the same strain rate as the first domain, but higher temperature (>1080℃), with the intermediate mean value of activation energy about 328.8 kJ/mol. The third domain appears at higher strain rate (10 s-1) and temperature range of 1050 to 1140℃, with the largest mean value of activation energy about 605.05 kJ/mol. Three different constitutive equations are established in corresponding to domains. Microstructural observations in the third domain reveal non-uniform dynamic recrystallization (DRX) of homogeneous γ phase, which leads to the poor deformability and the highest Q value. In contrast, microstructures in the first domain show fully DRX of homogeneous γ phase, leading to the better deformability and the lowest Q value. It is noted that the grain size increases with the increment of strain rate or temperature. These results suggest that bulk metal working of this material may be carried out in the first domain where fully DRX of γ homogeneous occurred.Fuwei Kang Jianfei Sun Guoqing Zhang Zhou Li 2009Journal of Materials Science & Technology2009,25,3:1
