WebMFH resulted in a significant decrease in cell viability when exposed to a magnetic field for 120 minutes and allowed to rest for 48 hours, compared with similar field applications, but with shorter resting time. The results presented here suggest that MFH most likely induces apoptosis in both cell types. When compared with HWH, MFH produced a ... In an aqueous solution, precipitation is the process of transforming a dissolved substance into an insoluble solid from a super-saturated solution. The solid formed is called the precipitate. In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is … See more The precipitation of a compound may occur when its concentration exceeds its solubility. This can be due to temperature changes, solvent evaporation, or by mixing solvents. Precipitation occurs more rapidly from a strongly See more An important stage of the precipitation process is the onset of nucleation. The creation of a solid particle implies the formation of an interface with the solution. This involves energy changes depending on the dissolution reaction free energy (endothermic See more While precipitation reactions can be used for making pigments, removing ions from solution in water treatment, and in classical qualitative inorganic analysis, precipitation is also commonly used to isolate the products of an organic reaction during workup and … See more Hydroxide precipitation is probably the most widely used industrial precipitation process in which metal hydroxides are formed by adding See more Precipitation in aqueous solution A common example of precipitation reaction in aqueous solution is that of silver chloride. … See more Proteins purification and separation can be performed by precipitation in changing the nature of the solvent or the value of its dielectric constant (e.g., by replacing water by See more In solid phases, precipitation occurs if the concentration of one solid is above the solubility limit in the host solid, due to e.g. rapid quenching or ion implantation, and the temperature is high enough that diffusion can lead to segregation into precipitates. … See more
