Dissociation Dissociation (Dissolving) is a process where the positive and negative ions of a substance come apart as an ionic compound dissolves in a solvent, like water. Dissociation is reversible because the original ionic compound does not change, therefore dissociation is a physical change ONLY ...
We find that most of the investigated modern MMVF can be classified as “High-alumina, low-silica wool”, but several were on or beyond the borderline to “pre-1995 Rock (Stone) wool”. We then used well-established flow-through dissolution testing at pH 4.5 and pH 7.4, with and ...
Xanthan gum is modified with formaldehyde to improve the dissolution rate. The FT-IR spectra and the X-ray diffraction spectra both show that chemical modification reduces intermolecular interactions and crystallinity. Viscosity measurements show that the chemically modified gum dissolves more rapidly than...
One of the objectives of developing nanoparticles of drugs in a solid state is to increase the solubility of the drug while maintaining its stability. Particle size reduction is increasingly emerging to modify the specifications of solid forms such as solubility, stability, dissolution rate and bioava...

It is the rarest form of murder-suicide but the one with the highest social toll per incident. Most types of murder-suicide involve morbid forms of attachment between perpetrator and victim, especially when the relationship is threatened with dissolution, and/or impulsive personality traits. ...

sometimes accompany dissolution phenomena due to prolonged time spent in the solution, the sensitivity to the deformation rate results from the effects of plasticity and plasticity-liquid metal interaction. Deformation rate effects are sometimes coupled with the effects of the bath's chemistry (Figure ...
