1B12N12纳米笼:潜在的二氧化氮检测传感器显示文摘利用密度泛函理论通过计算吸附能量、HOMO/LUMO能隙变化、电荷转移、结构扭曲等研究二氧化氮分子在B12N12纳米笼的吸附.此外,通过计算B12N12的电子结合能、Gibbs自由能、态密度和分子表面的静电势研究其稳定性和其它特性.B12N12纳米笼吸附二氧化氮显示三种构型.B12N12团簇的HOMO/LUMO能隙变化对二氧化氮分子的存在非常敏感,从自由团簇的6.84eV降为N02/团簇稳定团簇的3.23eV.团簇的导电性被极大地提高,表明B12N12纳米簇可能是潜在的二氧化氮气体分子检测传感器.Javad Beheshtian Mohammad Kamfiroozi Zargham Bagheri AliAhmadi Peyghan 2012Chinese Journal of Chemical Physics2012,25,1:4
2Effect of Low-Pressure Nitrogen DC Plasma Treatment on the Surface Properties of Biaxially Oriented Polypropylene, Poly (Methyl Methacrylate) and Polyvinyl Chloride Films显示文摘In this study, commercial biaxially oriented polypropylene (BOPP), polyvinyl chloride (PVC) and poly (methyl methacrylate) (PMMA) films were treated with nitrogen plasma over different exposure times in a Pyrex tube surrounded by a DC variable magnetic field. The chemical changes that appeared on the surface of the samples were investigated using Fourier transform infrared (FT-IR) spectroscopy and attenuated total reflectance Fourier transform infrared (ATR- FTIR) spectroscopy after treatment for 2 min, 4 min and 6 min in a nitrogen plasma chamber. Effects of the plasma treatment on the surface topographies and contact angles of the untreated and plasma treated films were also analyzed by atomic force microscopy (AFM) and a contact angle measuring system. The results show that the plasma treated films become more hydrophilic with an enhanced wettability due to the formation of some new polar groups on the surface of the treated films. Moreover, at higher exposure times, the total surface energy in all treated films increased while a reduction in contact angle occurred. The behavior of surface roughness in each sample was completely different at higher exposure times.S. Hamideh MORTAZAVI Mahmood GHORANNEVISS Soheil PILEHVAR Sina ESMAEILI Shamim ZARGHAM S.

3伊朗法尔斯省Poshtband地区植物的生活型和地理分布(英文)显示文摘在Postband地区(27°58′4″-28°2′16″N,53°17′34″-53°22′30″E),辨别植物种、植物多样性、生活型及地中海气候、Irano-Torunian和撒哈拉-新店相关植物种。2008年6月至2006年12月间,调查和辨认了29个科,69个属,总计95个种。就物种频度而言,菊科和禾本科是重要的科。按照Raunkiaer's生活型谱系统和利用■2检测,生活型谱表明,年生植物、地面芽植物、高位芽植物、地上芽植物和陷芽植物分别占据全部植物种的47%、31%、12%、7%和3%。在地理分布上,Irano-Torunia地区,拥有最高的频度的29%的物种。结果表明,一年生植物比生活型基准群谱高;高位芽植物比生活型基准群谱低,这与在干旱地区的研究数据相一致。图1表4参50。Gholamhosein Moradi Mohammad Reza Marvie Mohadjer Ghavamodin Zahedi Amiri Anoushirvan Shirvany Nosratollah Zargham 2010Journal of Forestry Research2010,21,2:2
4First Principles Study on Encapsulation of Alkali Metals into ZnO Nanocage显示文摘进 Zn12O12 nanocage 的碱金属(李, Na, K,和 Rb ) 的封装用密度被调查了功能的理论。李和 Na 原子的封装被发现在 298 K 和 100 kPa 热力学地有利,与否定吉布斯一起大约 130.12 和 68.43 kJ/mol 的免费精力变化 G 分别地。由增加包含的原子的尺寸这个过程变得不太有利以便在 K 和 Rb 封装的情况中 G 价值是积极的。结果显示 LUMO,费密水平,并且特殊,簇的人被转移到更高的精力以便簇的 HOMO-LUMO 差距显著地在所有案例中被缩小。在碱金属的封装以后,簇的工作功能由于费密水平的移动被减少到更高的精力。因此,从 Zn12O12 簇的射出的电子电流密度将被增加。Mohammad T.
