Coupled Fluid–Structure–Acoustic Analysis of Flow‐Induced Noise Control Using an Elastic Baffle in a Micro Channel

Energy Science &Engineering, EarlyView.
This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

Macromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Identifying the pre‐Odra river system with hydroacoustic and seismic reflection imagery offshore Rügen Island, southern Baltic Sea

Boreas, EarlyView.
Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...
