The presence of simple inorganic salts during zeolite synthesis turned out to be an effective and easy to handle alternative to organic additives to induce the growth of layer-like zeolite morphologies.

Long Chain

Ice frozen from a melt containing a small amount of a light alcohol, ketone, or ether is much weaker than normal ice, for a limited freezing exposure. The weakening effect is enhanced if the melt also contains traces of one or more of a variety of long-chain, organic substances, one of the most effective being sodium carboxymethyl cellulose. Inorganic salts, on the other hand, appear to be largely ineffective and may even cancel out the weakening action of the organic solvent. It is suggested that the organic additives are concentrated in the surface of the melt and remain as liquid layers between the ice crystals, thereby causing a large reduction in the shear strength of the ice sheet. Adsorption at the surface is discussed as a mechanism for concentrating organic substances in the surface layer and rejecting inorganic salts into the interior of the solution.

The City

This work demonstrates a possibility of composting of municipal waste waters sludge (WWS) digested during 5-7 days, of the Kuryanovo waste water treatment plants (the city of Moscow) without the use of traditional organic additives – sawdust, peat, thatch. As a recycling filler (repeatedly used), enhancing the porosity of the composted mixture, ribbed polyethylene spheres (∅=8 cm) and wood chips (having dimension of 5-10 cm) were used. Composting was performed efficiently in both cases, however, the use of wood ships had technological and economical advantages. The process of composting was carried out during 2-4 weeks and was composed of classical phases of active heating (a rate of 0.2-0.3oC/h was obtained), maintaining of maximum temperature during 1-2 days, and cooling down to the ambient temperature. During the course of composting, a product was obtained, having attractive organoleptic properties, suitable for application in municipal laying-out of greenery.

Water Solutions

In porous materials filled with water or water solutions of inorganic salts, water freezes at lower temperatures than under normal conditions; the reason is the decrease of water vapor tension above the convex meniscus of liquid in pores. The freezing point depression is not very significant in pores with radii from 0.05 μm to 10 μm (about 0.01-2.5 K). Only in smaller pores, especially when filled with inorganic salt solutions, this depression is important.
