Reassessing the organic carbon budget in the Murchison meteorite through an extraction–recovery mass‐balance approach

Meteoritics &Planetary Science, EarlyView.
Abstract A substantial fraction of organic carbon in carbonaceous chondrites has long been described as “missing,” reflecting incomplete recovery and limited resolution of operationally defined organic components. Here, we present a quantitative reassessment of the carbon budget in the Murchison meteorite using an integrated extraction–recovery mass ...

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Mechanistic Insights and Performance Advancements in Flow Capacitive Deionisation for Sustainable Energy Conversion

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT Flow capacitive deionisation is an advanced electrochemical technology for water purification and energy‐related applications. It represents a viable alternative to conventional desalination methods due to its low operating voltage, continuous electrode regeneration, and stable performance under moderate‐to‐high salinity conditions. The use of

Tunable Natural Deep Eutectic Solvents‐Driven Fractionation of Olive Pomace in an Integrated Biorefinery: Linking Lignin Structural Tailoring to Carbohydrate Valorization and Biopolymer Production

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Microwave‐conditioned olive pomace was fractionated with deep eutectic solvents (DESs) spanning acidic, neutral, alkaline, and chemo‐enzymatic regimes. The alkaline DES provided the best balance between delignification and carbohydrate preservation, yielding a fermentable glucose/xylose stream suitable for Haloferax mediterranei fermentation and poly(3‐

Tunable Conversion of Ammonia to Hydrazine or Ammonium Nitrite Induced by Acoustic Cavitation Bubbles

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
We show here that, depending on the gaseous atmosphere used, energy released at the acoustic cavitation bubble collapse time can be harnessed to activate and selectively convert ammonia into either hydrazine or ammonium nitrite, without assistance of any catalyst, “simply” through the application of ultrasonic waves.

Numerical study of high speed separated flows

, 2014
Instability, flow separation and transition are essential aspects of high speed flows with shock-wave/boundary-layer interaction. Supersonic flows with jet injection, compression ramp and cavity, either individually or in combination, are numerically ...
