The problem of long-term memory in water medium is studied. We have discovered that under the action of weak nonionizing low-frequency irradiation there are very essential modifications of water properties: decrease of viscosity of activated water by 10-100 times (at low velocity of water motion); change of electrical conductivity and permittivity by 10-20 times at low frequencies; increasing and time-dependent oscillations of pH exponent during several weeks etc. Duration of internal storage of these abnormal characteristics of activated water equals several hours, days or weeks at low temperature. The effectiveness depends on time of activation.
Detailed studies have shown that "clathrate" model is the one closest to reality. Unification of atoms of O and H can create spatial flexible tetrahedral frames. In the joints of the crystalline frame there are large empty micro cavities (clathrate cells) with rigid atomic walls and with diameter about 5.2 A. Beyond this frame there are quasi free molecules of "regular" isotropic water. Micro cavities are linked to the outer space by "windows" with diameter about 2.5 A, which is less than diameter of water molecule (about 2.76 A). In the result, each of micro cavities is separated from "external" water by circular potential barrier V=1.1 eV. In the volume of micro cavities different molecules may be accommodated.
With violation of thermodynamic balance a redistribution of molecules between amorphous water and the volume of micro cavities takes place until a new balanced state is achieved. Spontaneous transfer between these states is substantially inhibited due to a very small probability of tunnel transition of water molecules and the time of existence of each of these conditions turns out to be very big. Each such a clathrate cell is the single memory cell.
We have calculated the time of relaxation (duration of "water memory") of nonequilibrium population of foreign molecules in such clathrate cell. At T=1C, T=20C, T=36.6C and T=70C duration of "water memory" in single clathrate cell are equal τ=300 days, 10 days, 24 hours and 1 hour. The maximal volume density of recorded information for such "water memory" is about 10^21 bit/cm^3. The methods of recording and reading of such information are discussed. |
