Application

Luperox®DI, tert-Butyl peroxide has been used as a radical initiator to induce free radical polymerization. It has also been used as a cetane enhancer in a study to determine the phase behavior of carboxylate-based extended surfactant reverse micellar microemulsions with ethanol and vegetable oil/diesel blends.

Both high static repellency and pressure resistance are critical to achieving a high-performance omniphobic surface. The cuticles of springtails have both of these features, which result from their hierarchical structure composed of primary doubly reentrant nanostructures on secondary microgrooves. Despite

Peroxyl radicals, as model for peroxyl radicals formed during autoxidation of lipids, have been generated in three solvent systems (cyclohexane, tetrahydrofuran and tert-butanol/water) by steady-state and laser flash photolysis, and their reaction with beta-carotene studied. Steady-state photolysis experiments showed that
