The spheres of benzoic acid and 2-naphtol were prepared from p.a. grade material, which was molten and then poured into moulds made of silicone rubber to give spheres with approximate diameters of 11, 15, 19 and 25 mm.

Abstract.
The use of calcined clays as pozzolanic material in cement is known as early as the beginning of the twentieth century [1].
The fineness of the ground material was 3654 (cm2/g) Blaine.
On the durability of Portland limestone cement: effect of pH on the thaumasite formation HBRC Journal (accepted, in press)

The water uptake and loss is thus also of fundamental importance for the
proper functioning and the long-time stability of polymer exchange membrane fuel cells (PEMFC),
because it is related to irreversible dimension changes of the material and a morphological
instability, which can be connected to the mechanical properties of the membrane, especially its
elastic modulus.
The mechanism through which the adsorbates penetrate into the material is not discussed in detail; the existence of the various is is simply the result of local Langmuir isotherms that control the net balance between the evaporation and condensation rates.
