a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
methodology of islamic principles (‘ilm al-uṣūl) is a dignified science serving to understand religious texts; on the other hand, however, this science is indebted to holy qur’ān for its credibility and authority. the qur’ānic verses play a special role in validating and authorizing this science. this role is to be viewed in terms of foundation-laying, as āyāt al-uṣūl (verses of principles) are...
This paper describes a theoretical exploration of aesthetics ideals of gameplay. Starting from observations about the game artifact, several gameplay properties that can affect the aesthetical experience are identified, e.g. tempting challenges, cohesion, and gamer interaction. These properties are then used to describe several aesthetical ideals of gameplay, e.g. emergence, reenactment, medita...
for a given riemannian manifold (m,g),it is an interesting question to study the existence of a conformal diffemorphism (also called as a conformal transformation) f : m ! m such that the metric g? = fg has one of the following properties: (i)(m; g?) has constant scalar curvature. (ii)(m; g?) is an einstein manifold.
vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
In Early Modern times, techniques of assembling, compiling and arranging pre-existing material were part the established working methods in many arts. world 18th-century opera, such practices ensured that operas could become a commercial success because substitution or compilation arias fitting singer's abilities proved best recipe for fulfilling expectations audiences. Known as »pasticcios« si...
