TL;DR: In this article, the authors measured gas adsorption on a variety of micro and mesoporous materials using very slight surface coverage using nitrogen, oxygen, and krypton above their critical temperatures.
Abstract: Adsorption on a variety of micro- and mesoporous materials has been measured for very slight surface coverage using nitrogen, oxygen, and krypton above their critical temperatures The results show that the quantity of gas adsorbed is a function of the surface area of the adsorbent and the polarizability of the adsorbate

TL;DR: In this article, a new analytic isotherm equation is derived for adsorption of condensable vapors on mesoporous solids, which explicitly accounts for the effects of the pore size distribution of the adsorbent, the vapor-solid interaction and the adorbate size on the adorption process.

TL;DR: In this article, the influence of the surrounding atmosphere on sintering rate was monitored by the reduction in specific surface area, ΔS/S0, as a function of calcination time, t.
7 citations
TL;DR: In this article, the porous structure and surface area of alumina-supported cobalt molybdena catalysts were examined as functions of their activation conditions, and it was revealed that the process of reduction by hydrogen as well as simultaneous reduction by a hydrogen and hydrogen sulphide mixture results in the disappearance of pores of larger diameters.

TL;DR: In this article, NiO/SiO2 catalysts with Ni contents ranging from 2−15% using a microporous silica support at pH 11.5 were investigated using X-ray diffraction, TG and DTA.
