Flexible-robust hydrogen-bonded organic frameworks(HOFs)are attracting increasing interest due to their excellent separation performance for important industrial gases,but the construction remains ***,a sticked-layer strategy is first proposed to construct a flexible-robust HOF,HOFFJU-8,from a donor(D)–π–acceptor(A)molecule 4,4′,4″,4‴-(pyrrolo[3,2-b]pyrrole-1,2,4,5-tetrayl)tetrabenzonitrile(DP-4CN).HOF-FJU-8 is amicroporous three-dimensional framework composed of two kinds of DP-4CN molecules,one acting as building units for the two-dimensional layer via C≡N···H–C hydrogen bond dimers and another as the sticks to link the layers along channels through D–Aπ···π*** activated framework HOF-FJU-8a possesses flexible-robust pore characteristics,as determined by the gas adsorption and in situ gas-loaded powder X-ray ***-FJU-8a exhibits adaptive adsorption and stronger binding affinity to C_(2)H_(2)rather than CO_(2)due to the flexible-robust nature,which can effectively separate acetylene and carbon dioxide mixtures.

Nitrogen doping is usually adopted in carbon based supercapacitor to enhance its relatively low energy density by providing extra ***,the improvement of energy density is normally limited because the content of the introduced nitrogen species is not high and meanwhile only part of them is electrochemically ***,we designed and fabricated a class of hierarchical nitrogen-rich porous carbons(HNPCs)possessing not only very high nitrogen content(up to 21.7 atom%)but also fully electrochemically active nitrogen species(i.e.,pyridinic N,pyrrolic N and oxidized N).Especially,in the synthesis of HNPCs,graphitic carbon nitride(g-C3N4)was used in situ not only as a nitrogen source but also as a catalyst to facilitate the polymerization of phenol and formaldehyde(as carbon precursor)and as a template to create the hierarchical porous *** electrodes for aqueous symmetric supercapacitor,the HNPCs with full faradaic-active nitrogen functionalities exhibit excellent supercapacitor performance:high energy density of 36.8 Wh/kg at 2.0 kW/kg(maintaining 25.7 Wh/kg at 38 kW/kg),superior rate capability with 78%capacitance retention from 1.0 to 20 A/g and excellent cycling stability with over95%capacitance retention after 10000 cycles,indicating their promising application potential in electrochemical energy *** novel carbon material with high-content and full electrochemically active nitrogen species may find extensive potential applications in the energy storage/conversion,catalysis,adsorption,and so on.

The probability of 5He particle emission has been affirmed theoretically [J.S. zhang, Science in China G47 (2004) 137]. In order to describe the 5He emission, the theoretical formula of the double-differential cross section of emitted 5He is to be established. Based on the pick-up mechanism, used for calculating the formula of d, t, 3He, α emissions, the theoretical formula of double-differential cross section of 5 He is obtained, which is expressed in the form of Legendre coefficients. In the case of low incident energies, the configuration [J.S. zhang, Science in China G47 (2004)137; J.S. zhang, Commun. Theor. Phys. (Beijing, China) 39 (2003) 83] is the dominant part in the reaction *** calculated result indicates that the forward peaked angular distribution of the composite particle emission is weaker than that of the emitted single nucleon due to pick-up nucleon from the Fermi sea. As an example, the reactions of n + 14N have been calculated, and the Legendre coefficients of d, t, 3He, α, 5He emissions are obtained *** results show that the forward tendency is decided by the average momentum per nucleon in the emitted composite particles. The larger the average momentum is, the stronger the forward tendency is.

受海洋贝类对固体表面超强黏附现象的启发,采用盐酸多巴胺对竹塑复合材料进行增强改性。分别使用多巴胺添加量为0、0.25%、0.50%、1.00%处理了毛竹竹粉,制备出竹粉/高密度聚乙烯复合材料D0、D0.25、D0.50、D1.00。竹粉与复合材料的分析方法包括傅里叶变换衰减全反射红外分析、X射线衍射法、物理力学测试、SEM和接触角法。结果显示:多巴胺可以作为竹粉/高密度聚乙烯体系有效的表面改性剂,不同多巴胺添加量改性后材料的弯曲强度和拉伸强度都有提高。适合的多巴胺添加量是0.50%,材料的拉伸强度和弯曲模量分别提升7.74%、27.78%。不同多巴胺添加量处理的竹粉具备相同结晶结构。多巴胺添加量不同,一定程度改变了竹粉的分子结构。SEM分析显示,D0.50中竹粉分散均匀,与聚乙烯结合最为紧密。多巴胺抑制了竹粉的亲水性能,使得改性竹粉水接触角增大。

利用Fluent软件预测了风力机翼型在覆冰状态下的气动性能和气动噪声,采用大涡模拟与基于Lighthill声类比的FW-H模型相结合的方法模拟了不同覆冰状态下的声压级频谱和功率谱密度分布特征,分析了攻角和来流风速对声压级频谱和功率谱密度分布特征的影响。结果表明:覆冰使翼型的气动性能下降,升力减小,气流与壁面提前分离并进入失速区;明冰对翼型气动性能的影响最显著,霜冰次之;翼型覆冰后气动噪声明显增大,尤其覆明冰时翼型的气动噪声更突出;翼型覆冰前后气动噪声均随攻角增大而提高,未达到和超过失速攻角时气动噪声分别呈低频离散特性和宽频特性;来流风速对气动噪声的影响体现在总声压级上,各监测点的总声压级均随来流风速的增大而增强。
