The 27 Al and 29 Si magic‐angle spinning nuclear magnetic resonance (MAS‐NMR) study of the kaolinite‐mullite transformation has shown presence in tetra‐ pentacoordination dehydroxylated kaolinite. NMR signal analysis samples heated above 400°C demonstrates that tetrahedral sheet kaolinite begins to break down near 600°C continues do so 900°C. From evolution, it can be deduced exothermic peak at 980°C DTA curves is associated with modification coordination Al, which changes from or more...

In this study, we present an alternative maximum power point tracking technique used in a solar water pumping system to produce the for modifying amount of pumped water. This was actually created primarily regulate duty ratio buck converter. order control array operating track point, nonlinear approach based on input–output feedback linearizing and Lyapunov stability theory is used. By adjusting irradiation level, introduced controller-containing photovoltaic generator direct current (DC)...
We optimized Origanum majorana (OM) extraction for mild steel corrosion inhibition in neutral 0.5 M chloride medium. The mechanism evolved presence of the optimal extract was discussed when calculating activation energy (Ea), enthalpy (ΔaH) as well entropy (ΔaS). OM molecules were investigated using density functional theory (DFT) at B3LYP/6-31G(d,p) basis set level. 1-methyl-4-propan-2-ylcyclohexa-1,3-diene alpha-terpinene predicted exhibiting most capabilities.
