“…Apart from the DMPO–OH adduct signal, some additional peaks were constantly produced that were more pronounced in Figure B (curve f). A very clear DMPO–OH signal was found in control experiment Figure B (curve d), and a similar observation in aqueous medium was also reported for only the bicarbonate solution . One possibility may be the existence of minor dissolved O 2 in reaction medium that may interact with the transition metal catalyst producing ·OH or other active ROS.…”

Toxic and bioresistant compounds have attracted researchers to develop more efficient and cost-effective technologies for degradation of organic compounds in wastewater. This work demonstrates the degradation of 4-chlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, and phenol as model compounds using bicarbonate-activated H2O2 oxidation system in the presence of supported catalysts. The catalytic activity of the catalyst was investigated in term of degradation of target compounds, chemical oxygen demand (COD), and total organic carbon (TOC) removals both for batch mode and in fixed bed reactor using CoMgAl-HTs and CoMgAl-SHTs, respectively. The leaching of cobalt ion was efficiently prohibited because of the presence of a weakly basic medium provided by bicarbonate, and the CoMgAl-SHTs catalyst was found to retain its stability and good catalytic activity in fixed bed reactor for over 300 h. Extensive chemical probing, fluorescence, and electron paired resonance (EPR) studies were conducted to identify the actual reactive species in the degradation pathway, which revealed that the reaction proceeds through generation of superoxide, hydroxyl radical along with carbonate radical.

“…Among them there are both very fast and very slow reactions, which leads to a long evolution of the system (Bingi and Sarimov, 2014;Belovolova et al 2014). In water saturated with atmospheric carbon dioxide, hydrogen carbonate anions can act as electron donors and affect the course of conjugated chain electron-radical reactions (Voeikov, 2012). The initiator of these processes can also serve as natural sources of ionizing radiation, leading to the appearance of hydrated electrons.…”

The impedance of heavily diluted diclofenac centesimal potentiated solutions in the range of 20 Hz -10 MHz was studied. Each dilution was accompanied by vigorous shaking. The whole set of samples consisted of 33 iteration steps. Two parallel sets were prepared. There was no permittivity increment in the samples, which indicates the absence of mesoparticles with high dipole moment. At the same time, the resistance of the samples presented a non-monotonic character, including ultrahigh dilution samples, in which the concept of diclofenac concentration does not make sense. The pattern of both sets of samples turned out to be well correlated. The evolution of the resistivity patterns consisted of a decrease of the average value with a significant preservation of the shape of the pattern up to 30 days. This means that the result does not depend on the concentration of the solute, but on the sample preparation procedure. A hypothetical explanation of the observed effects consists in the appearance of reactive oxygen and nitrogen forms during mechanical perturbation of solution and the products of subsequent complex chemical reactions.

“…These modes act as stationary fields produced by the magnetic activity occurring in the shell whose boundaries are the surface of the earth-conductive ionosphere resonant cavity, which acts as a mirror wall for very-low-frequency (VLF) and Alfvén waves [51]. Aqueous solutions of bicarbonates, superoxide radicals, and other ROS, when excited, show variations in energy-emitting activity that have been found to correlate with fluctuations in the geomagnetic field [52]. Accordingly, bacterial and viral DNA sequences have been found to induce low-frequency EMFs in high aqueous dilutions [53].…”

Normal water structures are maintained largely by interactions with biomacromolecular surfaces and weak electromagnetic fields, which enable extended networks for electron and proton conductivity. All standard chemistry is totally reliant on electrostatics and avoids all mention of electrodynamics and the consequent radiation field, which is supporting the notion of water as a primary mediator of biological effects induced via electromagnetic means into living systems. Quantum Electrodynamic (QED) field theory have produced a vision of water in a liquid state as a medium, which for a peculiarity of its molecular electronic spectrum reveals itself as an essential tool for long-range communications, being able to change its supra-molecular organization in function of the interaction with the environment. This paper draws attention to the fact that interfacial water (nanoscale confined water) has been shown, independently by Emilio Del Giudice et al. and by Gerald Pollack et al., to contain respectively Coherence Domains (CDs) and Exclusion Zones (EZs), which may be regarded as long-range ensembles of CDs, dynamic aqueous structures, which uses the special properties of water, such as its electron/proton dynamics and organized response to electromagnetic fields, to receive electromagnetically encoded signals endowed with coherence (negentropy) at a low frequency, and sum the resultant excitations, so as to foster the redistribution of that coherence at frequencies which may affect biological systems.
