Effects of solvent, supersaturation ratio and silica template …

Solvents, supersaturation ratios and silica templates play a significant role in polymorphic nucleation of vanillin from solution. Stable form I and metastable form II of vanillin nucleate in aqueous solution at low supersaturation ratios ( S < 7) and high supersaturation ratios ( S = 7), and higher supersaturation ratio ( S = 8) leads to ...

Silica (Frac) Sand Mining

Silica sand (also commonly referred to as frac sand) is a crucial ingredient in the oil and natural gas extraction process known as fracking. The hydraulic fracturing ("fracking") process for oil and gas takes a mixture of proppant (usually frac sand), water, and chemicals and injects this mixture into a well under very high pressure.
