در این کار رفتار الکتروشیمیایی کمپلکس هایcd[os(ch3)2]2(no3)2 و cd (c6h5nh2)2(no3)2 cd[oc(nh2)2](no3)2 بررسی شده است. تکنیک مورد استفاده در این کار ولتامتری چرخه ای بود که بر روی الکترود طلا انجام گرفت. کمپلکس ها در حضور kno2 ، 05/0 مول بر لیتر به عنوان الکترولیت حامل، رفتار برگشت ناپذیری نشان می دهند بنابر این پارامترهای سینتیکی شامل ضریب نفوذ، ضریب انتقال، انرژی آزاد استاندارد فعالسازی کمپل...
the present paper deals with criminal issues. for example, legal injunction on the necessity of returning a deposit has a legal nature and legal injunction on the punishment of those who breach the trust has a criminal nature. existing social issues are the basis of classification of some instances into the issue, some of which are based on variation and others on quality. therefore, the motiva...
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 ...

Entropy is one of the few physical properties of a system that cannot be measured directly, but must be deduced or calculated from other properties. It is also a property that has been defined in a rather abstract sense and has not been connected to another observable property or physical variable. Since its formulation as a thermodynamic property, entropy has been linked to the concepts of ord...
A thermodynamic argument is proposed in order to discuss the most appropriate form of the local energy balance equation within the Oberbeck-Boussinesq approximation. The study is devoted to establish the correct thermodynamic property to be used in order to express the relationship between the change of internal energy and the temperature change. It is noted that, if the fluid is a perfect gas,...
