This study rigorously investigated the effect of charge-enhanced dry impregnation (CEDI) method on the physicochemical properties and catalytic performance of a ceria-supported nickel-based catalyst. The primary objective of the CEDI method was to augment the electrostatic adsorption of the nickel precursor onto the ceria support surface during the dry impregnation (DI) process. For a ...
Semiconductor metrology is a specialized branch of measurement science that ensures the accuracy and precision of semiconductor manufacturing processes. The evolution of semiconductor technology, from early microprocessors to today’s highly advanced integrated circuits (ICs), has been driven by the demand for smaller, faster, and more efficient electronic devices. As semiconductor ...
