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
2Sensing behavior of BN nanosheet toward nitrous oxide: A DFT study显示文摘In order to develop a sensor for the detection of toxic N2 O molecules, the interaction of pristine and Aldoped BN nanosheets with an N2 O molecule was investigated using density functional theory calculations. It was found that unlike the pristine sheet, the Al-doped sheet can effectively interact with the N2 O molecule so that its electronic properties and conductivity are dramatically changed. We believe that replacing a B atom of the BN sheet with an Al atom may be a good strategy for improving the sensitivity of these nanosheets toward N2 O, which cannot be trapped and detected by the pristine sheet.Marjaneh Samadizadeh Ali Ahmadi Peyghan Somayeh F.Rastegar 2015Chinese Chemical Letters2015,26,8:3
3Foliations on the tangent bundle of Finsler manifolds显示文摘Let M be a smooth manifold with Finsler metric F,and let T M be the slit tangent bundle of M with a generalized Riemannian metric G,which is induced by F.In this paper,we prove that (i) (M,F) is a Landsberg manifold if and only if the vertical foliation F V is totally geodesic in (T M,G);(ii) letting a:= a(τ) be a positive function of τ=F 2 and k,c be two positive numbers such that c=2 k(1+a),then (M,F) is of constant curvature k if and only if the restriction of G on the c-indicatrix bundle IM (c) is bundle-like for the horizontal Liouville foliation on IM (c),if and only if the horizontal Liouville vector field is a Killing vector field on (IM (c),G),if and only if the curvature-angular form Λ of (M,F) satisfies Λ=1-a 2/R on IM (c).PEYGHAN Esmaei TAYEBI Akbar ZHONG ChunPing 2012Science China Mathematics2012,55,3:1

12Working Mechanism of a BC_3 Nanotube Carbon Monoxide Gas Sensor显示文摘Carbon and BN nanotubes have previously demonstrated extreme sensitivity to several molecules, but they cannot be used to detect highly toxic molecules of CO. In this work, we examine the possibility of a BC3 nanotube (BC3NT) as a potential gas sensor for CO detection by using density functional theory calculations. It is found that CO molecule can be absorbed on B and C atoms of BC3 NT wall with adsorption energies in the range of 1.0 to 25.9 kcal/mol and it can donate finite charge to the tube. By comparing the HOMO/LUMO energy gaps of the bare and CO adsorbed nanotubes, we deduce that molecular CO can induce significant change in the electrical conductivity of the tube. The conductivity change can generate an electrical signal, which might be useful for CO detection.Ali Ahmadi Peyghan Sirous Yourdkhani anMaziar Noei 2013Communications in Theoretical Physics2013,60,7:0
133-Bihom-ρ-Lie Algebras, 3-Pre-Bihom-ρ-Lie Algebras显示文摘The purpose is to introduce the notions of 3-Bihom-ρ-Lie algebras and 3-preBihom-ρ-Lie algebras.The authors describe their constructions and express the related lemmas and theorems.Also,they define the 3-Bihom-ρ-Leibniz algebras and show that a3-Bihom-ρ-Lie algebra is a 3-Bihom-ρ-Leibniz algebra with theρ-Bihom-skew symmetry property.Moreover,a combination of a 3-Bihom-ρ-Lie algebra bracket and a Rota-Baxer operator gives a 3-pre-Bihom-ρ-Lie algebra structure.Zahra BAGHERI Esmaeil PEYGHAN 2023Chinese Annals of Mathematics,Series B2023,44,2:0
14A computational study of AlN nanotube as an oxygen detector显示文摘Interaction of O2 molecule and a zigzag aluminum nitride nanotube(AlNNT) was studied based on the density functional theory.The O2 molecule is adsorbed on the surface of AlNNT with the adsorption energies in the range of 11.0 to 12.1 kJ/mol.Geometrical structure of the AlNNT remains intact in the presence of oxygen molecule while its electronic structure dramatically changes so that its HOMO(or SOMO)-LUMO gap is approximately reduced to half of its original value.It suggests that the AlNNT may be used as a gas sensor for the O2 detection.Mohammad T.Baei Ali Ahmadi Peyghan Zargham Bagheri 2012Chinese Chemical Letters2012,23,8:0
