Environmental Toxicology, EarlyView.ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

The Material Basis of 18th‐Century Meissen Porcelain
Archaeometry, EarlyView.ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Engineered surface strategies to manage dental implant‐related infections
Periodontology 2000, EarlyView.Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Self‐Regulating Sodium‐Ion Battery Materials: From Phase Reconstruction to Functional Activation
Advanced Materials, Volume 38, Issue 19, 1 April 2026.Self‐regulating sodium‐ion batteries hinge on programmable phase behavior in layered oxides, interphases that renew without growth, and electrolytes that steer solvation and chemistry. This review distills mechanisms into design rules that span composition, site and entropy tuning, and self‐buffering anodes, linking operando evidence to choices and ...

Enhancing the Oxygen Evolution Performance by Introducing NiO‐Supported Mesoporous Titanium Dioxide
ChemistryOpen, Volume 15, Issue 4, April 2026.Herein, a schematic representation of the synthesis of NiO‐supported mesoporous TiO2 is reported. The process involves self‐assembly of polyvinylpyrrolidone (PVP), Ti(acac)2, nickel salt, and ethanol, followed by solvent evaporation, thermal polymerization, and stepwise calcination under N2 (350 °C) and air (450 °C) to remove PVP and carbon, yielding ...

Polarons in Heterogeneous Photo(electro)Catalysts
Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.Polarons are defined as quasiparticles consisting of electrons/holes covered by a cloud of virtual phonons, which are beneficial/detrimental to the electronic properties of materials. This minireview provides a conceptual overview of how small polaron formation influences the photon absorption, charge transport and separation, and surface reactivity in
