in the paper we developed a new method to determine the absolute amount of adsorption. this method relies on the excess adsorption isotherm and the density profile in the pore of one material. to compute the density profile and decrease complex calculation of obtaining the absolute amount of adsorption we introduced simplified local-density (sld) model. a few of appropriate parameters were acqu...

One of the most beautiful theories of condensed matter is certainly the theory of conventional superconductivity. Called the BCS theory after the names of the creators (Bardeen, Cooper and Schrieffer), it explains the zero resistance appearing in particular materials when their temperature approaches absolute zero. In the BCS theory, electrons are bound together by an attractive interaction and...

Recent results of quantum field theory on a curved spacetime suggest that extremal black holes are not thermal objects and that the notion of zero temperature is ill-defined for them. If this is correct, one may have to go to a full semiclassical theory of gravity, including backreaction, in order to make sense of the third law of black hole thermodynamics. Alternatively it is possible that we ...
