| 1 | Growth of carbon nanotube arrays on various CtxMey alloy films by chemical vapour deposition method显示文摘Carbon nanotube(CNT) arrays were fabricated on Ct-Me-N-(O) alloys with content of Ct in the range of 6–40 at.% by chemical vapour deposition. The Ct was a catalytic metal from the group of the following elements: Ni, Co, Fe, Pd, while Me was a transition metal from the group of Ⅳ–Ⅶ of the periodic table(where Me = Ti, V, Cr, Zr, Nb, Mo, Ta, W, Re). Carbon nanotubes were found to grow efficiently on the alloy surface with its composition containing Ti, V, Cr, Zr, Hf, Nb or Ta. The growth of CNTs was not observed when the alloy contained W or Re. Additions of oxygen and nitrogen in the alloy facilitated the formation of oxynitrides and catalyst extrusion on the alloy surface. Replacement of the metals in alloy composition affected the diameter of the resulting CNTs. The obtained results showed that the alloy films of varying thickness(10–500 nm) may be used for the CNTs growth. The resulting CNT material was highly homogenous and its synthesis reproducible. | Pawel Mierczynski Sergey V.Dubkov Sergey V.Bulyarskii Alexander A.Pavlov Sergey N.Skorik Alexey Yu Trifonov Agnieszka Mierczynska Eugene P.Kitsyuk Sergey A.Gavrilov Tomasz P.Maniecki Dmitry G.Gromov | 2018 | Journal of Materials Science & Technology2018，34，3： | 2 |
| 2 | Thermodynamic potential and phase diagram for multiferroic bismuth ferrite(BiFeO_(3))显示文摘We construct a Landau-Ginzburg thermodynamic potential,and the corresponding phase diagram for pristine and slightly doped bismuth ferrite,a ferroelectric antiferromagnet at room temperature.The potential is developed based on new X-ray and neutron diffraction experiments complementing available data.We demonstrate that a strong biquadratic antiferrodistortive-type coupling is the key to a quantitative description of Bi_(1−x)La_(x)FeO_(3) multiferroic phase diagram including the temperature stability of the antiferromagnetic,ferroelectric,and antiferrodistortive phases,as well as for the prediction of novel intermediate structural phases.Furthermore,we show that“rotomagnetic”antiferrodistortive-antiferromagnetic coupling is very important to describe the ferroelectric polarization and antiferrodistortive tilt behavior in the R3c phase of BiFeO_(3).The Landau-Ginzburg thermodynamic potential is able to describe the sequence of serial and trigger-type phase transitions,the temperature-dependent behavior of the order parameters,and the corresponding susceptibilities to external stimuli.It can also be employed to predict the corresponding ferroelectric and antiferrodistortive properties of Bi_(1−x)La_(x)FeO_(3) thin films and nanoparticles by incorporating the gradient and surface energy terms that are strongly dependent on the shape,size,and preparation method. | Dmitry V.Karpinsky Eugene A.Eliseev Fei Xue Maxim V.Silibin Alexandra Franz Maya D.Glinchuk Igor O.Troyanchuk Sergey A.Gavrilov Venkatraman Gopalan Long-Qing Chen Anna N.Morozovska | 2017 | npj Computational Materials2017，，1： | 1 |
