共赏新月之辉,同庆新岁之始。2024年是农历甲辰龙年,自年初起,大街小巷便洋溢着龙年的氛围寄寓着人们对新一年的美好期盼。龙,这一传说中的神圣生物,承载着人们对于风调雨顺的祈愿。作为十二生肖中唯一一种现实中不存在的动物,龙却是最受崇拜的神兽之一,被视为古代中国皇权的象征。《尔雅·翼·释龙》记载了龙的外形特征:“角似鹿、头似驼、眼似兔、颈似屋、麟似鱼、爪似鹰、掌似虎、耳似牛。”古代人认为龙是由八种动物的特点结合形成的物种,所以龙又被称为“鳞虫之长”。

Approximate analytical solution of the Dirac equation with q-deformed hyperbolic Poschl–Teller potential and trigonometric Scarf II non-central potential

引用

Chinese Physics B 2015年第3期24卷 48-54页

作者： ade Kurniawan A.Suparmi C.Cari Physics Department Sebelas Maret University

An approximate solution of the Dirac equation for a spin-1/2 particle under the influence of q-deformed hyperbolic P ¨oschl–Teller potential combined with trigonometric Scarf II non-central potential is studied analytically. It is assumed that the scalar potential equals the vector potential in order to obtain analytical solutions. Both radial and angular parts of the Dirac equation are solved using the Nikiforov–Uvarov method. A relativistic energy spectrum and the relation between quantum numbers can be obtained using this method. Several quantum wave functions corresponding to several states are also presented in terms of the Jacobi Polynomials.

Effects of reduction on the catalytic performance of limonite ore

引用

Journal of Energy Chemistry 2018年第5期27卷 1489-1495页

作者： Keisuke Abe ade Kurniawan Takahiro Nomura Tomohiro Akiyama Graduate school of Engineering Hokkaido University Sapporo 060-8628 Japan Center for Advanced Research of Energy and Materials Hokkaido University Sapporo 060-8628 Japan

The catalytic performance of Ni-containing limonite ore in the dry reforming reaction of methane （CH_4＋CO_2→2H_2＋2CO） was determined before and after hydrogen reduction, and under a flow of hydrogen. After hydrogen reduction, the limonite ore exhibited higher catalytic performance, because of the formation of Fe-Ni. However, the Fe in Fe-Ni was readily oxidized by the input CO_2 gas. resulting in a rapid decrease in the catalytic performance of limonite ore. The performance de- crease was due to a decrease in the Ni surface area; Ni could not dissolve in iron oxides and this caused segregation in the iron oxides. When the reaction was conducted under a hydrogen flow, the Fe-Ni was formed and maintained. Ni was highly dispersed in the Fe-Ni phase, resulting in greater surface area of Ni and higher conversion rate of CH_4 and CO_2. The catalytic performance of the limonite ore was inferior to the Ni/Al_2O_3 catalyst because the effect of catalyst support was small, however, the limonite ore was more stable during catalytic use and much cheaper than the Ni/Al_2O_3.
