Preparation and Thermoluminescence Properties of Polycrystalline Na2SO4/SiO2 composite

Brazilian Journal of Radiation Sciences
A sodium sulphate/silica (Na2SO4/SiO2) composite was prepared by a sol-gel procedure using a geode as the silica source. The prepared sample was characterized by XRD, XRF and IR techniques.

Seismic Reflection Profiling at the Kentland Impact Structure, Indiana: Geophysical Characterization of Impact Induced Damage

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The Kentland Impact Structure is a classic complex crater whose central peak is exposed in an active quarry in NW Indiana, USA. However, its diameter has remained poorly constrained due to the thick glacial sediment cover. Newly obtained seismic reflection profile images combined with refraction seismic tomography, earlier gravity surveying ...

Flood Modelling Evaluation in a Semiarid Catchment: The Role of a Soil Mineralogical Index From Satellite Imagery

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT The Mediterranean region is characterized by the occasional occurrence of intense rainfall events. Along with lithological, geomorphological, and land use factors, these events influence the hydrosedimentary dynamics of drainage basins, potentially causing torrential floods.

Basement Geometry and Cover‐Basement Relationships in the Central‐Western Jaca‐Pamplona Basin (Southern Pyrenees): Along‐Strike Variations and Role of Structural Inheritance

Tectonics, Volume 45, Issue 6, June 2026.
Abstract This study presents a detailed, geometrical characterization of the central‐western domain of the Jaca‐Pamplona Basin based on a combined interpretation of seismic and surface data and the construction of four serial cross‐sections. For the studied portion of the basin, our results highlight that the basement is notably folded and faulted and ...

Integrated VES–ERI–MASW‐Geotechnical Investigation for Building Foundation Site Suitability at the Proposed Wachemo University Referral Hospital, Hosanna, Central Ethiopia

Engineering Reports, Volume 8, Issue 5, May 2026.
Integrated VES, ERI, and MASW surveys, constrained by boreholes, delineate a central low‐resistivity/low‐V s weak corridor and more competent volcanic strata at depth. The eastern sector offers preferable foundation conditions, while identified weak zones require ground improvement or deep foundations to mitigate differential‐settlement risk.

COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1617-1627, May 2026.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.
