Redox-mediated decoupled seawater direct splitting for H2 production

open access: yesNature Communications
Seawater direct electrolysis (SDE) using renewable energy provides a sustainable pathway to harness abundant oceanic hydrogen resources. However, the side-reaction of the chlorine electro-oxidation reaction (ClOR) severely decreased direct electrolysis ...

Study on the Fragmentation Characteristics and Dust Generation Mechanism of Coal Cutting by Pick

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT During underground excavation, coal dust generation threatens miners' health and damages ecosystems. Its generation is directly influenced by cutting pick performance and inherent coal properties. This study investigates the effects of coal properties and cutting parameters on coal fragmentation characteristics from a mesoscopic perspective ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Rock dynamic strength prediction in cold regions using optimized hybrid algorithmic models

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Predicting the dynamic mechanical characteristics of rocks during freeze–thaw cycles (FTC) is crucial for comprehending the damage process of FTC and averting disasters in rock engineering in cold climates.

Dr. Hans Kohn and the political takeover of the Berlin Medical Society by the National Socialist regime in 1933

open access: yesThe Anatomical Record, EarlyView.
Abstract To solidify their power over society, totalitarian regimes will usually eliminate any dissent, any perceived threats early on. These threats include not only political enemies but also educated and independent segments of society, such as professional associations.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Under the Shade of a Coolabah Tree: A Second Cache of Tulas From the Boulia District, Western Queensland

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.
