Depth reduction materials are the complex refractory iron ore, and reduction process includes not only the reduction of iron oxides but also the reduction of other minerals and more complex reaction between the minerals [1].
The results showed that the restore sequence of iron oxide in reduction process is Fe2O3 → Fe3O4 → FeO → Fe; The depth reduction process can be divided into three stages: nucleation, reaction and grow, and the finally obtained metallic iron exists in reduction materials in the form of iron particles.

Attempts for improving the control authority of monolithic piezoelectric materials led to the making of piezoelectric composites (PZC) wherein the monolithic piezoelectric materials are used as reinforcement embedded in a conventional epoxy matrix.
These PZCs exhibit wide range of effective material properties which are not offered by the existing monolithic piezoelectric materials.

Machine learning (ML) algorithms can improve and innovate the design of new, eco-friendly composite materials.
Introduction Artificial intelligence (AI) can potentially revolutionize the experimental approach in materials science research, as AI enables the identification of hidden patterns in experimental databases, reducing the cost and time that it takes to develop new materials experimentally.
Using this optimized iterative imputer provides an accurate method to estimate values of missing data for CNC-reinforced PVA composites in material science research.
Therefore, machine learning models can significantly enhance the development and research for new environmentally friendly composite materials.
