Ultraviolet Extinction of Metal Oxide Nanoparticles Imaged at the Single Nanoaggregate Level
Particle &Particle Systems Characterization, Volume 43, Issue 4, April 2026.Metal oxide nanoparticles are at the core of many nanotechnology applications, yet their tendency to form complex nanoaggregates imposes the development of alternative characterization methods. UV microscopy is introduced here to monitor the extinction cross‐section of TiO2, SnO2 and Fe2O3 nanoparticles with single nanoaggregate resolution of ...

Polarization Changes in Lunar Simulant Soil: The Role of Incident, Reflection, and Off‐Plane Angles
Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract Observing the polarization of the lunar regolith is essential for obtaining detailed information about the composition and characteristics of lunar soil. Observations conducted via lunar orbiters facilitate polarization measurements over wide areas; however, achieving very high‐resolution imaging requires either a large optical system or a ...

High‐Refractive‐Index La2O3–Nb2O5–WO3 Ternary Glasses Prepared Using a Levitation Technique
International Journal of Applied Glass Science, Volume 17, Issue 2, April 2026.ABSTRACT Colorless and transparent La2O3–Nb2O5–WO3 (LNW) glasses were successfully synthesized using a levitation technique in a wide glass‐forming region. These glasses exhibited excellent optical properties, including a high refractive index (>2.1) with low wavelength dispersion, and high transmittance (70%‒75% at a thickness of ∼800 µm) in the ...
