در این مقاله گذار فاز مغناطیسی و ناهمسانگردی مغناطوالاستیکی یک نمونه بس بلور nd14dy2fe78b6 به کمک اندازه گیری پذیرفتاری مغناطیسی متناوب و مغناطوتنگش گزارش شده است. این ترکیب به روش ریخته گری از مذاب تهیه شد. تصاویر sem و طیف xrd آن نشان داد که نمونه بس بلور و غیر تک فاز بوده و عمده ترین ترکیب موجود در ان فاز 1- 14- 2 است. اندازه گیری پذیرفتاری مغناطیسی متناوب نشان داد که نمونه در دمایی در حدود ...
Organoimidoylization of Polyoxometalates (POMs) can dramatically modify the electronic structures of POMs and gives rise to novel "value-adding" properties of the POMs for promising material applications including photo-electronic transformation and catalysis. To date, the preparation of multi-functionalized organoimido derivatives of POMs is generally conducted under strict condition and is ti...
Individuals experiencing high levels of social anxiety report frequent and intense anger. Yet, little is known about how they manage this emotion. Despite general tendencies towards anger suppression, subsets of individuals with social anxiety regulate anger through outward expression. In this study, we investigated rejection as an antecedent to anger, examined how and when individuals with hig...
The extended abstract describes a method for recognizing similar sub-parts of objects described by 3D polygonal meshes. The innovation of this method is the coupling of structure and geometry in the matching process. First of all, the structure of the shape is coded in a graph where each node is associated to a sub-part of the shape. Then, the matching between two shapes is approached using a g...
In this report, using computational methods of quantum mechanical the study of structural, electronic and orbitals properties of Catapres on nanostructured fullerenes using software Gaussian 98 is done. At the first compounds were optimized, then NBO calculations have been done. The results indicate changes of energy levels HOMO & LUMO, dipole moments, bond distance of N61-C<sub...
