List of publications studying the interconnection of the physical-chemical properties of UHDs.
The term ‘interconnected’ denotes symbatic changes in various properties of solutions in a range of their dilutions (up to UHD). For example, Ryzhkina et al. (2015) showed that pH, electrical conductivity and light scattering change in an interconnected way.
The table will be updated over time.

Among the dilutions of Abs to IFNg, extrema of electrical conductivity and pH values were observed in C9, and self-organizing nanoobjects are present in C7 and C9 (as well as in C13, C30, and C50). |

Concentration dependences of particle size and electrical conductivity (χ) of 2,4,6,8-tetramethyl-2,4,6,8-tetraazabicyclo[3.3.0]octane-3,7-dione (Mebicar) solutions were nonlinear. Two concentration ranges can be distinguished (1•10-9 – 1•10-6 M and 1•10-17 – 1•10-12 M), where these parameters change in the same direction, with extrema at 1•10-7 M and 1•10-14 M. |

The formation of nanoassociates in highly diluted solutions of potassium salt of β-(4-hydroxy-3,5-di-tert-butylphenyl)-propionic acid (potassium phenosan) resulted in the nonmonotonic concentration dependences of the physical-chemical properties (zeta potential and electrical conductivity changed in the same direction, and both changed in the opposite direction with respect to surface tension) and correlated with their biological effects. |

The luminescence intensity dependence of sodium chloride centesimal dilutions on the level of dilution is a nonmonotonic function with several maxima: at D1-D2 and at D13-D14. A negative correlation of luminescence intensity with the Spirostomum ambiguum infusoria motor activity in the test samples was found. |

There was a relationship between the nonmonotonic concentration dependences of the dispersed phase (nanoassociates) size, physical-chemical properties (electrical conductivity, and pH), and fluorescence intensity (λex 225 nm, λem 340 nm) of a multicomponent dispersed system based on the N-(phosphonomethyl)glycine herbicide and its effects in the range of calculated concentrations of 1•10-19 – 1•10-3 g•L-1 on the development of some hydrobionts and inhibition of root growth of Triticum vulgare (wheat). The results indicated that a coherent change in fluorescence intensity, physical-chemical properties and bioeffects was associated with the rearrangement of nanoassociates as the systems were diluted. |

In the concentration dependences of the bioeffect (determined by the number of green algae cells) and the particle diameter of a solution containing succinic acid and RoundUp (36% N-(phosphonomethyl)-glycine and 64% nonionic surfactant polyethoxylated tallow amine), extrema in the concentration range of 1.0•10-17 g•L-1 coincided. |

Nanoassociates were formed when preparing ultrahigh dilutions of the potassium salt of β-(4-hydroxy-3,5-di-tert-butylphenyl) propionic acid (potassium phenosan) after a threshold concentration of 1.0•10-8 M in the presence of a geomagnetic field. The diameter of nanoassociates changed in the same direction with electrical conductivity and bioeffects and in a different direction with surface tension. In the absence of a magnetic field (when solutions were isolated in a permalloy container), nanoassociates were not formed, and there were no differences either in the physical-chemical properties of solutions from water or in bioeffects. |

Nanoassociates were formed when preparing ultrahigh dilutions of cetyltrimethylammonium bromide or α-tocopherol after a threshold concentration of 1.0•10-8 M in the presence of a geomagnetic field. Changes in the same direction in electrical conductivity, pH (for cetyltrimethylammonium bromide), and bioeffects (inhibition of protein kinase C by α-tocopherol) and changes in the opposite direction with surface tension were detected. In the absence of a magnetic field (when solutions were isolated in a permalloy container), nanoassociates were not formed, and there were no differences either in the physical-chemical properties of solutions from water or in bioeffects. |
