Abstract

This study investigates the surface characterization of anodized aluminium using natural dyes. Aluminium anodizing is an electrochemical process that produces a thick oxide layer on the aluminium surface. This layer can be coloured using various dyes. The purpose of this research is to analyze the effect of anodizing time on surface characteristics when using natural dyes such as turmeric. The results show that anodizing time significantly affects surface morphology and colour absorption.

Abstract

This research focuses on the synthesis and characterization of spinel zinc ferrite (ZnFe2O4) using coprecipitation method. The study examines the structural, morphological, and magnetic properties of the synthesized materials. The results indicate that coprecipitation method produces ZnFe2O4 nanoparticles with uniform size distribution and good crystallinity.
