Mass-energy conversion

Besides, without addictive AICI3 as a crystal conversion agent, phase composition of most neogenic Ti02 particles was anatase in our experiment. Conversions active energy finm anatase to rutile was 460 kJ/mol [5], with temperature arose, crystal conversion rate as well as mass fraction of rutile would increase [6,7]. Hence, after a lot of heat accumulated, phase composition of particle-sintered layer was rutile.

Nuclear mass is always lower than the sum of proton and neutron masses because of mass-energy conversion, which transforms part of the mass into binding energy. For example, He has mass 4.002604, whereas the total mass of two protons and two neutrons is 4.032981. Based on Einstein s equation... 

Mossbauer spectroscopy is based on transition between energy levels of nuclei with different values of the nuclear spin quantum number /. When a nucleus emits a y-ray, the energy of the emitted radiation is lowered by the recoil of the nucleus. Conversely, the energy needed for absorption is higher than that needed for transition, because the absorbing nucleus absorbs energy in the recoil process. For nuclei tightly bound in solids, however, the effective mass of the emitter and... 

It is seen, therefore, that the cell potential V and consequently the efficiency of an electrochemical converter (Fig. 13.9) are determined by the activation overpotential, by the electrolyte conductance, and by mass transfer (i.e., the solubility of the reactants). The factors that dominate the way the efficiency of the conversion of energy changes with an increase in current density are at low current density, the activation...
