“…The concentration of salt in our bodies corresponds to the minimum required for optimal prevention of bubble coalescence [200][201][202]. As small bubbles are much less harmful than large bubbles, this fact is crucial [203][204][205]. pH sensitive phase transitions have been suggested as mechanisms for cellular action [159].…”

Abstract:In reviewing the literature pertaining to interfacial water, colloidal stability, and cell membrane function, we are led to propose that a cascade of events that begins with acute exogenous surfactant-induced interfacial water stress can explain the etiology of sudden death syndrome (SDS), as well as many other diseases associated with modern times. A systemic lowering of serum zeta potential mediated by exogenous cationic surfactant administration is the common underlying pathophysiology. The cascade leads to subsequent inflammation, serum sickness, thrombohemorrhagic phenomena, colloidal instability, and ultimately even death. We propose that a sufficient precondition for sudden death is lowered bioavailability of certain endogenous sterol sulfates, sulfated glycolipids, and sulfated glycosaminoglycans, which are essential in maintaining biological equipose, energy metabolism, membrane function, and thermodynamic stability in living organisms. Our literature review provides the basis for the presentation of a novel hypothesis as to the origin of endogenous bio-sulfates which involves energy transduction from sunlight. Our hypothesis is amply supported by a growing body of data showing that parenteral administration of substances that lower serum zeta potential results in kosmotropic cationic and/or chaotropic anionic interfacial water stress, and the resulting cascade.Keywords: inflammation; serum sickness; colloidal instability; interfacial water stress; bio-sulfates; Shwartzman phenomena; sudden death syndrome Glossary of TermsAnaphylaxis a severe, rapidly progressing, life-threatening, generalized allergic reaction. Biological equipoise a stable, non-equilibrium, dissipative system synonymous with life. Cholesterol sulfate (Ch-S)quantitatively the most important known sterol sulfate in human plasma where it regulates the activity of the serine proteases, in cell membranes where it has a stabilizing role, and in platelet membranes where it supports platelet adhesion. Coherence domain (CD)a water CD is a collection of liquid water molecules which oscillate in unison in tune with a self-trapped electromagnetic field at a well-defined frequency. The coherent oscillations produce an ensemble of quasi-free electrons, able to collect noise energy from the environment and transform it into high-grade coherent energy in the form of electron vortices. This high-grade energy may then activate biomolecules resonating with the water CD. Colloidal instabilitya property attributed to a colloidal suspension that develops when stabilizing repulsive steric and electrostatic forces between colliding particles are insufficient to prevent their natural tendency to aggregate into masses large enough to precipitate.Colloidal suspension a colloid that has a continuous liquid phase in which a solid is suspended in a liquid, e.g., our flowing blood. Exclusion zone (EZ)a glass-like, gel phase consisting of water CDs resonating in-phase, adjacent to hydrophilic surfaces, several hundred micrometers wide which excludes colloi...

“…Various techniques such as NMR, IR and X-ray scattering have been used to determine the ordering and mobility of the water molecules in the layers (Nickolov et al, 2005;Pouliquen et al, 2001;Slade et al, 1991;Turov et al, 2005). Molecular dynamics simulation that combines physics, mathematics and chemistry is an advanced research method to study the radial distribution of water molecules around particles.…”

Hydration layer on clay mineral surfaces is originated from the adsorption of polar water molecules and hydrated cations on the surfaces through unsaturated ionic bonds, hydrogen bonds and van der Waals bonds. It has attracted great attentions because of their important influences on the dispersive stability of the particles in aqueous solutions. This review highlighted the molecular structure of clay minerals, the origin of hydration layers on clay mineral surfaces, the hydration layer structural model, hydration force and the main parameters of affecting the hydration layers on clay minerals (crystal structure, cationic type and strength, and solution pH). Also, the research methods for hydration layers were briefly described, especially the determination of hydration layer thickness by the Einstein viscosity method and AFM method. In addition, the applications of the stability of fine clay mineral particles in aqueous suspensions were summarized.Keywords: Hydration layers; clay minerals; dispersion; hydration force Warstwa uwodniona na powierzchni minerałów ilastych (gliniastych) powstaje w wyniku adsorpcji polarnych cząsteczek wody i uwodnionych kationów powierzchniowych wiązanych za pomocą nienasyconych wiązań jonowych, wiązań wodorowych i wiązań van der Waalsa. Zagadnienie to wzbudza wiele uwagi ze względu na to, że w dużej mierze warunkuje stabilność dyspersyjną cząstek w roztworach wodnych. W pracy omówiono strukturę molekularną minerałów ilastych, powstawanie warstw uwodnionych na powierzchni minerałów ilastych i siły hydratacji; przedstawiono także model strukturalny warstwy uwodnionej oraz główne parametry warunkujące powstawanie warstwy uwodnionej na powierzchni materiałów ilastych (struktura krystaliczna, rodzaj występujących kationów, stężenie roztworu i jego pH). Ponadto, pokrótce przedstawiono metody badań, ze szczególnym uwzględnieniem badania grubości warstw uwodnionych przy zastosowaniu modelu lepkości Einsteina oraz metody AFM. Ponadto, zestawiono zagadnienia związane ze stabilnością cząstek drobnoziarnistych minerałowa ilastych i ich potencjalne zastosowania.Słowa kluczowe: warstwy uwodnione, minerały ilaste, dyspersja, siła hydratacji

“…It is likely that the ions reside in the interfacial region, between the exterior surface layer and interior bulk water molecules, where the hydrogen bonding is naturally most disrupted (Paul and Chandra, 2004). A similar phenomenon is the bubble (cavity) attachment to microscopic salt particles used in microflotation, where chaotropic anions encourage bubble formation (Nickolov and Miller, 2005). Further explanation for coalescence involves the effect of the ions on raising or lowering gas solubility (Weissenborn and Pugh, 1996) and this explanation may be extended to water-gas surfaces, as if some ions increase the solution of gasses at the interface, they will reduce the surface tension by this effect alone.…”

SummaryThere is considerable disagreement over whether the gas/liquid surface of water is positive due to the presence of surface-active hydrogen ions or negative due to the presence of surface-active hydroxyl ions. Much has been written and many experimental and simulation studies have been undertaken. We critically analyze these studies to establish what is known unambiguously and what assumptions underlie these opposite views. The conclusion reached after this examination is that there is much misunderstanding over the strength of the evidence for hydrogen ions being surface active and less support for the positive surface than generally regarded. The surface of neutral water is negatively charged.
