Studies in Chemistry and BiochemistryScience can do much good for mankind or can cause a catastrophe for mankind if it is handled by terrorists, (even aircraft can be turned into weapons of destruction as we have seen on September 11 2001 in New York City and Washington DC) This volume deals with science for the sake of mankind. Chemical physics, which combines chemistry and physics, and biochemical physics, which combines chemistry, physics and biology, have been developing quite radically recently. This holds true for pure and applied science as well. Some examples of such success are given in this book. Included in this volume are papers from Russian scientists, scientists from the republics of the former USSR and papers from scientists in western countries. |

Page 189 - Table 6 the comparison of the sample 8 possessing low homogeneity with the sample 9 possessing high homogeneity shows that the coefficient of the first one is 4-fold lower, than that of the second one at the same content of the filler. Moreover, comparison of the samples 8 and 10 shows that the electrically conducting composite with low content of the filler may possess higher absorption properties, if filler particles are distributed uniformly in the polymer matrix.
Page 217 - The disordered nanocomposites also inhibit oxygen and combustible "fuel" species transfer by increasing the path length of these species to the flame front. The path length is dramatically increased due the surface area of the silicates (approximately 700 m2/g for Na+ montmorillonite). There is also a high possibility of alumina-silicate solid phase catalysis of polymer decomposition, which can dramatically change the overall scheme of thermal degradation process kinetics.
Page 213 - Polymer layered silicate (clay) nanocomposites are materials with unique properties when compared with conventional filled polymers. Polymer nanocomposites, especially polymerlayered silicates, represent a radical alternative to conventionally filled polymers.
Page 218 - ... combustion products and reactants [PhysProps 1.6 by G & P Engineering Software Co.]. The concept derives from the fact that enthalpy (H) is a state function and therefore its change in any process is independent of the path from reactants to products. Thus, the overall enthalpy of a reaction is the simply the sum of the enthalpies of the component reactions. In practice, the heat of combustion of the reaction can be calculated by subtracting the heat of formation of the products from the heat...
