15 صفحه اولA Theoretical Study on Thermal Conductivity of Zn - Nanofluid
A coupled molecular dynamics (MD)-stochastic model has been developed for predicting the thermal conductivity of a hypothetical water based Zn-nanofluid taking into account the heat transfer during and after collision of the nanoparticles with the heat source. The model has predicted a somewhat lower enhancement in thermal conductivity of water based Zn-nanofluid compared to water based Cu-nano...
متن کاملA theoretical study of stereochemistry in thermal 1,3-silyl migrations
Although a large number of concerted thermal 1,3-migrations of a group-14 element have been known, their mechanistic aspects are rather complicated. Following the WoodwardHoffmann rules, 1) suprafacial 1,3-migration with retention at the migrating center (suprafacial-retention) is symmetryforbidden; antarafacial-retention and suprafacial-inversion processes are allowed, though they are usually ...
متن کاملTheoretical study of tetrahedrane derivatives
Tetrahedrane is most strained and the smallest cage compound. It attracts organic chemists because ofits unusual bonding nature and highly symmetrical structure. However, many efforts to isolate theparent tetrahedrane have been unsuccessful because of the high reactivity and very short lifetimecaused by the strain in this molecule. Modeling of molecules for determination of structuralproperties...
متن کاملTheoretical Efficiency I N Pollution Control: Comment
In a recent issue of this JournuZ, Richard 0. Zerbe [7] considered the effects of alternative assignments of liability for damage in the field of pollution control and presented a useful categorization and analysis of alternative methods of achieving any particular level of control. In the process, Zerbe makes some rather strong claims for the “Coase theorem” which deserve further discussion. F...
