New Magnetite Reference Material for SIMS δ18O Measurements and a Study of Precision and Accuracy Due to Crystal Orientation Effects

Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 391-406, June 2026.
Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Temporal Change in Resistivity Structure Before and After the 2018 Small Phreatic Eruption Iwo‐Yama Volcano, Kirishima Volcanic Complex, Japan

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A small phreatic eruption occurred on April 2018 Iwo‐yama, Kirishima volcanic complex, Japan. We estimated the change in the subsurface resistivity structure before and after the phreatic eruption by repeated magnetotelluric (MT) measurements. A substantial decrease in resistivity was determined in the zone from the surface down to a depth of ...

An Unusual Presentation of Cutaneous Leishmaniasis in a Patient with Substance Use: A Diagnostic and Management Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT In patients with atypical ulcers and travel history to endemic areas, a comprehensive diagnostic workup for cutaneous leishmaniasis is imperative. This case confirms Leishmania tropica through combined microscopy, culture, and PCR, leading to successful treatment with systemic glucantime and adjunctive wound care.

High‐Velocity Ballistic Impact Performance of FFF Printed PEEK With Different Infill Patterns

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
This study examines 3D printed PEEK under Izod, quasi‐static, and high‐velocity impact. Hexagonal infill shows the highest Izod impact strength and superior quasi‐static energy absorption. However, under ballistic impact, all patterns behave similarly, indicating performance depends on infill at low velocity, but on intrinsic material properties at ...

Effect of Adatom Energy on the Interfacial and Surface Morphology of Pulsed DC Sputtered Ruthenium Thin Films

Surface and Interface Analysis, Volume 58, Issue 5, Page 326-333, May 2026.
ABSTRACT In the present study, we have analyzed the growth profile of ruthenium (Ru) thin films, deposited using pulsed direct current (DC) magnetron sputtering technique, by varying the sputtering voltages in the range of 150–420 V. The grazing incidence X‐ray reflectivity (GIXRR), time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS), and atomic ...
