Journal of the American Oil Chemists' SocietyYatagai, M., Komaki, M., Nakajima, T., Hashimoto, T. (1989) Composition of a Liquid Crystalline Phase Formed Between Aqueous Surfactant Solutions and Oily Substances.
A wide variety of substances has been proposed as air-entraining agents and pore-forming agents in the construction and building industries including (1) organic, surface-active substances; (2) substances that produce gas pores or gas bubbles in the not-yet-set concrete by triggering a chemical...
of chemical interactions between the deicing chemicals, cement hydration products,cementitious materials, and aggregates. Moreover, thesurface characterization techniquesare also used to elucidate the presence of microcracks in the specimens as a result of exposure to the deicing solutions. In essence,...

Both 1:1 and 1:2 chelate complexes are formed with D-gluconate at close-to-neutral pH. • In alkaline solutions, trinuclear species with Ca-L-Ca-L-Ca chains, are predominant. Abstract Of the sugar carboxylates, D-gluconate is clearly the most significant representative: the world’s ann...
Heating values for non-conventional components are calculated with a unified correlation valid for a wide range of substances (Channiwala and Parikh, 2002). Gas phase in HTL contains 85.3 mol% CO2, 0.9 mol% H2, 6.4 mol% CH4, 4.4 mol% CO, and 2.9 mol% N2. The gas phase in HTC ...

Thus in hitherto known patent and related literature no reference discloses the problem of poor stability of active substances that are unstable in acidic medium, unstable when stored in presence of water and at the same time sensitive to heating, being solved by transforming said active substance...
substances have greater anti-cancer activity than their parent compounds. It is clear that camptothecin and its derivatives have become a major focal point of medical research, particularly of research on anti-cancer drugs. However, because camptothecin is highly toxic to normal human cells, it ...
