Spatial Activity Patterning and Topological Defect Transport in Acoustically Energized Active Liquid Crystals

Small, EarlyView.
Channel geometry is used to pattern activity in acoustically energized active liquid crystals, producing controlled, directional transport of topological defects. The mechanism is revealed by experiment and minimal modeling, offering a new design principle for programmable topological transport and active microfluidic architectures. ABSTRACT Patterning

Identification of invisible damage in prestressed concrete bridges—A demonstrator case using coda wave interferometry

Structural Concrete, EarlyView.
Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.

Toward Metabolomics Analyses With Combined Capillary Vibrating Sharp‐Edge Spray Ionization and Atmospheric Pressure Chemical Ionization

Rapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale The varied properties of metabolomics components dictate the tools used in mass spectrometry (MS) characterization including the selection of the ionization source. However, the ionization of select compounds limits characterization efficiency.
