Resolving the Internal Magnetic Domain Structure of Cloudy Zone Tetrataenite

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Recent advances in magnetic imaging can directly capture the internal magnetization of natural and synthetic materials at resolutions <10 nm. This capability opens new possibilities to determine the magnetic domain state of ferromagnetic minerals that are fundamental for recording and retaining paleomagnetic records.

Evaluating TEMPO Formaldehyde Retrievals With Co‐Located Ground‐Based FTIR and Pandora Observations

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Formaldehyde (HCHO) is an important proxy for volatile organic compounds and photochemical activity, with significant implications for air quality and atmospheric chemistry. The recently launched geostationary satellite instrument Tropospheric Emissions: Monitoring of Pollution (TEMPO) provides the first‐ever hourly observations of HCHO and ...

Development of an optically stimulated luminescence radiometer based on sodium chloride and gold nanoparticles for improving radiation detection in radiography

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Purpose To evaluate sodium chloride doped with gold nanoparticles (NaCl + GNPs) as a low‐cost, reusable optically stimulated luminescence (OSL) material for diagnostic radiology, and to benchmark its luminescence performance against the commercial standard, aluminum oxide doped with carbon (Al2O3:C).

Blue stragglers en cúmulos abiertos

open access: yes, 1992
A review of the observational features of blue stragglers (BS) and their possible interpretations are presented. The binary hypothesis has been investigated by means of photometric UBV observations of 48 BS in old and intermediate age open clusters. One variable star has been found in NGC 2354, which resulted in a Beta Lyrae - type eclipsing binary ...
