Experimental and Comparative Study of the Corrosion Behavior of Lean Duplex Stainless Steel in Seawater

open access: yesMaterials and Corrosion, Volume 77, Issue 9, Page 1399-1423, September 2026.
The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

Source Effects in Higher‐Order Ambient Seismic Field Correlations

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Ambient seismic noise interferometry is widely used for surface wave imaging. It typically requires synchronous station recordings and assumes uniform noise source distributions. Higher‐order correlations, such as the re‐correlation of the reconstructed direct waves C2 $\left({C}_{2}\right)$, enable imaging with asynchronous data and can ...

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 5, Page 1255-1268, September 2026.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

A Dual-Channel Passive Limb Imaging System (DUALIS) for Mars with UV Airglow-Based CO2 Retrieval and 557.7 nm Doppler Wind Imaging Interferometry

open access: yesRemote Sensing
Characterizing both the CO2 distribution and wind dynamics in the Martian mesosphere and lower thermosphere is vital for planetary atmospheric science and mission planning. In this work, we propose a novel dual-channel passive limb-viewing imaging system designed to simultaneously observe partial CO2 column density and line-of-sight (LOS) wind speed ...

Non-invasive monitoring survey in Beppu hot spring area using gravity, passive image interferometry, and InSAR

open access: yes
Abstract This paper presents the findings of a comprehensive non-invasive monitoring survey of the reservoir in the Beppu hot spring area, which has the largest discharge and the highest average temperature among hot springs in Japan. Interferometric synthetic aperture radar (InSAR) indicates a settlement of 15 mm over the past decade ...

Temporal Variations of Crustal Properties in Northern Chile Analyzed with Receiver Functions and Passive Image Interferometry [PDF]

open access: yes, 2014
This thesis analyzes temporal variations of crustal properties in northern Chile. The seismic broadband stations of the Integrated Plate Boundary Observatory Chile which started operating in 2006 deliver the data for this work. In the neighborhood of the seismic stations a MW 7.7 earthquake occurred near Tocopilla on 14 November 2007 at 52 km depth ...

Passive seismic imaging of ore deposits using coda wave interferometry: a case study of Akanvaara V-Cr-PGE deposit in Northern Finland

open access: yes
Abstract. In this study, we present an innovative method to image the inner structure of orthomagmatic ore deposits using P-wave coda of regional seismic events. We combine data processing and interpretation schemes from conventional passive seismic interferometry and teleseismic receiver function (RF) method.

Passive seismic imaging of the orthomagmatic ore deposits using regional earthquake interferometry: a case study of the Akanvaara V-Cr-PGE deposit in Northern Finland

open access: yes
Abstract This paper presents a method for studying the structure of the subsurface in hard rock terrains by interferometry of the Pn-wave coda of the regional seismic events. Using theoretical background and application examples of the teleseismic coda wave interferometry and the teleseismic receiver function methods, we developed data ...
