Liquid-like phases of calcium carbonate have also been prepared by addition of acidic polypeptides to generate polymer-induced liquid precursor28. Recent work has demonstrated that liquid emulsions can be formed without the use of organic additives if the materials are levitated to prevent nucleation16...
1.Use of unleaded petrol. During combustion, leadcompounds react with other additives in petrol to form volatile lead halideswhich is toxic. Moreover, lead products can inactivate the catalysts incatalytic converters. 2.Installation of catalytic converters in carexhaust systems. NO, CO and unburnt ...
They are used for the removal of metal ions in the paint mixture during production, preventing them from precipitating any anionic surfactants or dispersants (e.g., sodium hexametaphosphate). (12) UV absorbers and stabilisers. These additives are of recent use. In fact, some synthetic polymers,...
search for synergistic additives to polysaccharides and the creation on their basis of new highly effective inhibitors of hydrate formation, economically feasible for industrial use; - search for the optimal molecular weight of polysaccharides for use as inhibitors of gas hydrate formation. This work is...

Promising areas may be: - functionalization of polysaccharides (introduction of carboxyl, amide and ether fragments); - increasing the degree of branching of the main chain of polysaccharides; - search for synergistic additives to polysaccharides and the creation on their basis of new highly effective...
