The transition temperature (340 K) and enthalpy change (3.7 + 0.5 kJ mo1-1) of the monoclinic-orthorhombic phase transition in highly siliceous zeolite ZSM-5 (Si/AI = 639) were measured by differential scanning calorimetry (d.s.c.). The transition temperature determined is in agreement with that due

Low density lipoprotein (LDL) cholesterol is known to be oxidized both in vitro and in vivo giving rise to oxygenated sterols. Conflicting results, however, have been reported concerning both the nature and the relative concentrations of these compounds in oxidized human LDL. We examined the extract
It has been found that Ga and In/H-ZSM-5 are active catalysts for selective NO reduction with methane, while the activities are retarded by water vapor, which particularly retards the oxidation of NO to NO2 on zeolitic Lewis acid sites, a necessary step for the reduction of NO with methane. In order
