Summary: This study investigates the impact of magnesium doping on the structural, optical, and dielectric properties of zinc oxide. The results show that magnesium is successfully doped into the zinc oxide lattice, resulting in a decrease in the dielectric constant and high dielectric loss at elevated temperatures. Additionally, magnesium doping decreases the band gap of zinc oxide, altering its electronic properties and optical behavior.

Summary: A fast and scalable method for producing nanostructured SiC from plant materials through magnesiothermic reduction was developed in this study, resulting in SiC with a crystallite size below 10nm and a high surface area. This approach paves the way for large-scale production of nanostructured SiC using renewable resources and also demonstrates the use of SiC as a metal adsorbent in applications such as wastewater remediation.

Summary: The study investigates the chemical and electrochemical oxidation processes of porous silicon formed from lightly-doped p-type silicon in aqueous electrolytes, monitored by photocurrent and explained quantitatively by proposed models. The valence of reaction during anodic oxidation was found to be approximately 1.5, consistent with non-stoichiometric oxide growth. The efficiency of luminescence improves in the initial stages of oxidation but decreases as silicon content decreases.

Summary: In this study, Fe-Ga films with macroporous structure were prepared by electrodeposition on metallized silicon substrates templated with sub-micrometer-sized polystyrene spheres, showing larger magnetic-field-induced crystal deformation compared to non-templated and fully-dense films. These effects in porous Fe-Ga films are promising for the design of various strain-engineered nanomaterials.

Summary: Electrical switching of nanophotonic structural color elements is a promising approach for addressable color switching pixels, but switching between primary colors and colorless state remains a challenge. This study presents a reversible electrical switching approach using electrocoagulation of Ag nanoparticles between silicon nanostructures with Mie resonances. The electrodeposited Ag nanoparticles enable a large spectral transformation through the excitation of hybrid plasmon-Mie resonance. This design outperforms others in electrotonic color control and is highly stable and reliable for use in high-resolution reflective displays.
