Background Solvatochromic dyes have demonstrated themselves to be useful probes in the molecular-level study of homeopathic potencies. The range of dyes available, and their broad division into two main electronic structural groups, is permitting a detailed investigation of the fundamental nature of potencies. The immobilisation of solvatochromic dyes on transparent membranes takes these investigations to a new level of investigative precision. Aims To attach as many different solvatochromic dyes as possible to triacetylcellulose membranes, and where successful, to observe in detail the spectroscopic changes that occur on exposure to potencies. Immobilisation of dyes onto membranes de-couples the initial dye-potency interaction from later aggregation processes, thereby allowing a host of questions to be asked about what exactly potencies are doing to solvatochromic dyes and in turn indicating what the identities of potencies are likely to be. Methodology A number of methods have been explored for covalently linking dyes to membranes, which at the same time maintain the integrity of the solvatochromic chromophore. Immobilised dyes, in contrast to dyes in solution, behave differently, which means water-insoluble dyes for instance, can be used under a range of solution conditions that were not possible previously. Results and discussion Results from three positively solvatochromic dyes show that potencies cause a bathochromic shift in their spectra, confirming what has been seen previously with encapsulated dyes but with greater clarity. Results can be explained by invoking a polarising effect of potencies and differential stabilisation of the dyes’ ground and excited electronic states. The kinetics of the dye-potency interaction indicate the effect of potency reaches a maximum and then declines. Conclusion Immobilisation of solvatochromic dyes presents a significant step forward in the ability to investigate homeopathic potencies at the physico-chemical level.

We investigated the effect of origin and some physico-chemical parameters on the kinetics of reduction with hydrogen of two series of mixed NiO-Fe2O3 oxides differing by their composition, the character of their precursors (mixed crystalline nitrates and coprecipitated hydroxides) and their decomposition temperature.This effect manifested itself by different magnitudes of specific surfaces of the mixed oxides and coherent regions of present phases as well as by different oxidizing abilities of the surface and differences in morphology and phase composition of corresponding samples in both series investigated. Nonlinear or nonmonotonous composition dependences of physico-chemical parameters investigated point to a mutual influence of individual components, which is also a function of the system origin and which modifies its reactivity during its reduction with hydrogen. The kinetics of the reduction was studied thermogravimetrically at 320-410 °C. The reduction of oxides of the hydroxide origin is catalytically accelerated by primarily reduced nickel, whereas in corresponding samples of the nitrate series, the total NiO is bound to the spinel phase and the reduction is delayed. Experimental IR spectra, the effect of preliminary annealing and DTA of the mixed oxides point to an inhibitory effect of water, which is constitutionally bound in trace admixtures of the goethite phase, on the kinetics of reduction of samples in the hydroxide series.

Abstract Background Highly diluted and succussed solutions interact with solvatochromic dyes, indicating that changes in solvent and solute polarity could be related to their mechanism of action. It is not known, however, how the activity associated with succussed high dilutions is transferred to untreated water and what the limits of this process are. Aims The aims of the present study were to ascertain whether a succussed high dilution of phosphorus (1.5 × 1−59 M; Phos 30cH) seeded into a natural water source that fed a fjord and two connected lakes could propagate itself through the lake system (total volume 2200 m3) and, moreover, whether the process could be tracked using solvatochromic dyes. Methods Samples of water were collected before and after seeding, at different times and places throughout the lake system. Controls comprised water taken from an untreated and adjacent, but independent, lake (1385 m3). Results Water samples taken up to 72 hours after the source treatment produced significant increases (p ≤ 0.03) in the absorbance of the solvatochromic dye methylene violet (MV), while samples from the control lake produced no changes. Conclusions The study indicates that activity associated with Phos 30c can propagate itself through large volumes of water, causing changes throughout a whole connected lake system, and that these changes can be tracked using the solvatochromic dye MV. This in turn means the use of homeopathic medicines in large volumes of drinking water, in farming and ecological contexts, now has the potential to be assessed with physico-chemical monitoring.
