A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

Magnetic Resonance in Chemistry, Volume 64, Issue 8, Page 711-728, August 2026.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

Permeation Properties of Polymer Nanocomposite Membranes for CO2 Separation: An Experimental and Machine Learning‐Based Optimization Approach

Polymers for Advanced Technologies, Volume 37, Issue 8, August 2026.
ABSTRACT The study aimed to optimize the gas permeation properties of polymer nanocomposite membranes through a combination of experimental investigations and machine learning (ML) techniques. Initially, polyacrylonitrile (PAN) and PAN‐polyethyleneimine (PAN‐PEI) nanocomposite membranes were fabricated and experimentally characterized to determine ...

Pressurization of Shallow Magma Reservoir Preceding Basaltic Eruptions at an Open‐Vent Volcano

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Open‐vent volcanoes are characterized by the persistent activity of outgassing, lava effusion and mild explosions, which is, however, occasionally interrupted by more violent explosive activity (paroxysm), for example, Stromboli (Italy). In spite of the different (two orders of magnitude) explosive intensities and different petrological magma ...

Imaging Near‐Surface Bedrock Fracturing and Fluid Pathways Using Seismic Attenuation and Velocity From Viscoacoustic Full‐Waveform Inversion of Refraction Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Seismic attenuation provides sensitivity to fracture density, fluid saturation, and pore geometry that complements velocity, enabling quantitative imaging of fracture architecture and associated fluid‐pathways in near‐surface bedrock. Yet high‐resolution attenuation models remain rare in refraction studies due to amplitude‐fidelity and ...

Insights Into Magmatic Degassing, Hydrothermal Dynamics, and Eruption Precursors From Long Term SO2 Emission Monitoring at Whakaari/White Island, New Zealand

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Long‐term SO2 emission rate time series are critical for deciphering the subsurface processes regulating open‐vent volcanoes, yet extracting cyclical drivers from continuous degassing records remains challenging. We analyze a 14‐year (2006–2020) SO2 emission rate data set from Whakaari/White Island, New Zealand, identifying five chronological ...

Ice Nucleation Enhancement in Ambient Aerosols Under High‐Salinity Conditions: Insights From Cloud Chamber Experiments

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Ice‐nucleating particles (INPs) play a role in mixed‐phase clouds, yet the processes controlling their properties remain poorly understood. Water‐soluble salts such as sodium chloride (NaCl) depress the freezing temperature of cloud droplets.
