Effect of Zinc Oxide Nanoparticles From Infant Formula Milk Powder on Colon Cells In Vitro

Journal of Applied Toxicology, Volume 46, Issue 10, Page 3437-3445, October 2026.
ABSTRACT Zinc is an essential trace element that participates in numerous metabolic processes; however, excessive exposure may interfere with the absorption of other metals, such as copper. In recent years, nanotechnology has experienced rapid growth, and zinc oxide nanoparticles (ZnO NPs) have garnered significant attention due to their versatile ...

Interactions and scattering of quantum vortices in a polariton fluid

Nature Communications, 2018
Superfluid flow around a vortex is quantized so that vortices become discrete, particle-like defects, with interactions mediated by the surrounding fluid.

Photoelectrochemical Water Splitting With TiO2 Thin Films: Effects of Thickness, Porosity, and Illumination Configuration

ChemElectroChem, Volume 13, Issue 18, 19 September 2026.
An increase in surface area is not always an advantage for photoanodes; mesoporous TiO2 photoelectrodes present lower photoelectrocatalytic performance in oxygen evolution reaction due to a higher density of surface states that promote recombination, especially under frontal illumination.

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.
