Low-Oxygen and Dense Mo10Cr Alloys Prepared via In-Situ Nanocarbon Deoxygenation and Two-Step Pressurization Hot Pressing

Metals
Hot pressing is a promising technique for fabricating high-density molybdenum (Mo) alloys; however, obtaining low oxygen content remains a significant challenge.

Photoactivation of Electron Donor–Acceptor Complexes Enables Deoxygenative Hydrogenation and Deuteration

Transformative Chemistry, EarlyView.
A photoinduced, NHC‐borane‐enabled radical deoxygenative hydrogenation featuring mild reaction conditions and excellent functional group tolerance has been developed. The reaction proceeds through a novel EDA complex photoactivation pathway. To explore the potential of NHC‐boranes in deuteration reactions, we developed a novel photoinduced protocol for

Nocturnal Hypoxia Reduces Aerobic Scope and Telencephalon Size in Cleaner Wrasse Despite Enhanced Inhibitory Control

Proceedings
Ocean deoxygenation is intensifying globally, and hypoxia is increasingly documented on tropical coral reefs; yet, its consequences for the physiology and social functioning of reef fishes remain poorly understood.

Review on the production of renewable biofuel: Solvent-free deoxygenation

Biofuel is an eco-friendly fuel that can reduce CO2 emissions by 65% compared to using petroleum-based fuels. The commercialized biodiesel, which contains oxygen atom within its molecules, is only used in blends with petroleum-based diesel, but renewable

Prognostic value of contrast‐enhanced ultrasound in dogs with acute renal injury treated with haemodialysis

Veterinary Record, Volume 196, Issue 6, 15/22 March 2025.
Abstract Background It is clinically relevant to predict outcomes in dogs with acute kidney injury (AKI) treated with haemodialysis. The aim of this study was to evaluate the prognostic value of contrast‐enhanced ultrasound (CEUS) and its role in discriminating between AKI and acute impairment associated with chronic kidney disease (AKI/CKD).

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

Fisheries Oceanography, EarlyView.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Strongly reducing sediments hinder restoration of a eutrophic coastal marine ecosystem

Environmental Research Letters
Anthropogenic activities are causing deoxygenation of coastal waters leading to degradation of such ecosystems globally. In the Dutch Southwest Delta, coastal management has turned tidal waters into marine lakes. The ensuing stagnation and stratification

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$
