Combining multibeam and single beam echosounders for quantifying gas bubble release from the seafloor

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Marine gas bubble release is a worldwide phenomenon that impacts the local marine ecosystem and contributes to carbon fluxes with respect to global warming. It is still challenging to assess gas flow for large seep areas (tens of km2), but recent advances in calibrating and processing multibeam echosounder (MBES) data make this problem ...

Fabrication of Lithium/Strontium‐Releasing Smart Bioactive Glasses with Anti‐Inflammatory and Osteogenic Effects Tailored to Pathological Stages

open access: yesMacromolecular Bioscience, EarlyView.
Bioactive glasses with controllable dual ion release capability are developed to aid bone regeneration. The bioactive glasses rapidly release lithium ions that exert an anti‐inflammatory effect, suppressing inflammation after bone injury. Simultaneously, the bioactive glasses slowly release strontium ions, which support bone formation by suppressing ...
