Numerical Simulation of Flow Field around Jacket Foundations on Flat-Bed and Equilibrium Scour Bathymetry

Journal of Marine Science and Engineering
In recent years, jacket foundations have been increasingly employed in offshore wind farms. Their complex design comprising piles and trusses poses challenges for conducting comprehensive flow field measurements using physical experiments.

Skeletal muscle adaptation to muscle activity and hypoxia: Differential structural and metabolic remodelling

The Journal of Physiology, EarlyView.
Abstract figure legend There has been controversy about the structural (capillary) response of skeletal muscle to altered O2 status, involving decreased supply (hypoxia) or increased demand (activity). Here we demonstrate that seven days of activation of skeletal muscle by indirect electrical stimulation led to significant expansion of the capillary ...

Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Comprehensive Analysis for the Evaluation of Torrential Floods and Slope Stability of River Channels: La China River Area (Colombia)

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
Colombia and other tropical regions face a very high threat from torrential floods, which have resulted in over 25,000 deaths in a single event. Unfortunately, there is no comprehensive assessment methodology to zone and determine the magnitude of these disasters; therefore, this research aims to help fill this gap.

Green and Low‐Carbon Synthesis of Lithium Sulfide (Li2S): From Fundamental Mechanisms to Scalable Manufacturing for Next‐Generation Energy Storage

Advanced Science, Volume 13, Issue 47, 24 August 2026.
This review focuses on green synthesis routes for lithium sulfide (Li2S)—a key material for lithium–sulfur batteries and sulfide solid electrolytes, whose traditional carbothermal reduction remains energy‐intensive and unsustainable. Specifically examined routes include low‐temperature solid‐state reactions, magnesiothermal reduction, and solution ...

Exploring Tradeoffs in Syngas Production With Solid‐Oxide Electrolysis via Multi‐Objective Optimization

Chemie Ingenieur Technik, Volume 98, Issue 8, Page 495-506, August 2026.
This work applies multi‐objective optimization to investigate trade‐offs between different objectives in syngas production with solid‐oxide cell co‐electrolysis. Two system designs are investigated. By systematically exploring tradeoffs between different objectives, insights, and comparisons of the operation of these designs are achieved.
