AbstractThe role of nucleation kinetics in affecting glass formation behavior is discussed. Also considered are measurements of homogeneous crystal nucleation in a variety of liquids. For a number of oxide glass-forming liquids, available data indicate pre-exponential factors which are larger than those predicted from classical nucleation theory by factors of 1017 to 1049. Possible sources of this discrepancy are discussed.

Zeolites and other inorganic molecular sieve membranes have shown potential for separation based on molecular size and shape because of their small pore sized, typically less than 1nm, and their narrow pore size distribution. The in situ synthesis of ZnAPSO-34 films supported on alumina substrates is reported in this paper. Organic and water contents, alumina source, and supports have important roles in the syntheses of ZnAPSO-34 film. Traditionally, the role of organic molecules in the synthesis of these materials has been associated to their structure-directing and their protonation abilities. In our work, we were interested in a new family of materials; the alumino-phosphate, which are similar to zeolites. This work concerns the in-situ preparation of films of ZnAPSO-34 on porous α -alumina tubes. These films of ZnAPSO-34 corresponding to the structure Chabazite (CHA) have an effective intracrystal nanopore diameter of 0.38 nm. The hydrothermal synthesis was made in an autoclave under autogenous pressure. The membrane used was characterized by thermo-gravimetric analysis (TGA) and differential thermal analysis, X-ray diffraction and scanning electron microscopy after calcination.

Recently, owing to the discovery of graphene, porous carbons experienced a revitalization in their explorations. However, nowadays, the focus is more on search for suitable energy advancing catalysts sensing, energy storage or thermal/light absorbing features than on separations. In many of these processes, adsorption, although not emphasized sufficiently, can be a significant step. It can just provide a surface accumulation of molecules used in other application-driving chemical or physical phenomena or can be even an additional mechanism adding to the efficiency of the overall performance. However, that aspect of confined molecules in pores and their involvement in the overall performance is often underrated. In many applications, nanopores might silently advance the target processes or might very directly affect or change the outcomes. Therefore, the objective of this communication is to bring awareness to the role of nanopores in carbon materials, and also in other solids, to scientists working on cutting-edge application of nonporous carbons, not necessary involving the adsorption process directly. It is not our intention to provide a clear explanation of the small pore effects, but we rather tend to indicate that such effects exist and that their full explanation is complex, as complex is the surface of nanoporous carbons.
