A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, Volume 55, Issue 5, Page 721-729, September/October 2026.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244 Cm sources, and come with severe concerns on radiation safety and isotope availability.

Temperature Dependent Complex Refractive Index (CRI) of Hexagonal Ice in the Range 150–270 K: Infrared and Far‐Infrared Transmission Measurements at the AILES Beamline

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The complex refractive index (CRI) of ice is one of the main parameters driving the optical properties of ice clouds and frozen surfaces, hence their climate impact. While already characterized at short wavelengths, ice CRI has never been measured across the infrared range at temperatures relevant to Earth.

Ultra‐Broadband Optical Characterization of TiO2 Nanotube Arrays Revealing Annealing‐Tunable THz Absorption

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Lithography‐free spaced TiO2 NT arrays unlock tunable broadband absorption from THz to UV. By harnessing annealing‐driven phase transitions, strong phonon–polariton resonances emerge in the 1.4–3.6 THz range, whereas high absorptance persists beyond 10 THz.
