Early exposure to titanium dioxide nanoparticles caused a decrease in the cytoplasmic catalase activity, inducing lipid peroxidation in the Saccharomyces cerevisae. [PDF]
The massive production of nanomaterials has created new pollutants whose interaction with living organisms is unclear. Recent studies have revealed that these materials generate reactive oxygen species, causing cell damage, when antioxidant systems fail,

Ceria‐Zirconia Supported Gold Nanoparticles for CO and Soot Oxidation
ABSTRACT This study introduces a gold nanoparticles catalyst (AuNPs) supported on ceria‐zirconia oxide, prepared by deposition‐precipitation (Au/CZ‐dep) and chemical reduction (Au/CZ‐red). The as‐prepared catalysts were tested in CO oxidation by O2 and soot oxidation under different oxidizing atmospheres (O2, NO2+NO+O2).

Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed
