Wide‐Flow Aerosol Jet Printing Enables High‐Throughput, Ultra‐Low Aspect Ratio Patterning

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
Wide‐flow aerosol jet printing (WF‐AJP) employs an anisotropic nozzle design to generate planar aerosol jets, enabling millimeter‐scale deposition of highly uniform, ultra‐low aspect ratio (<1:6000) films with substantially reduced anisotropy in functional performance.

Predicting structural disasters with Radar interferometry

open access: yesIABSE Reports, 2015
<p>Radar interferometry is a technique which can observe the earth’s surface during day and night time. It makes uses of thousands of pulses per second that are transmitted by satellites and reflected by the surface of, for instance, structures.

A Decadal Survey of the Near‐Surface Seismic Velocity Response to Hydrological Variations in Utah, United States

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Ongoing climate change is leading to an increase in prolonged droughts and severe weather events, which are particularly pronounced in semi‐arid regions, such as the western United States. These extremes could have lasting social and environmental impacts.
