Tailored Design of Iridium Single Atoms on Mn–Ni‐Phytate with Robust Bifunctionality for Enhanced Anion Exchange Membrane Water Electrolysis

Advanced Energy Materials, EarlyView.
This work presents a manganese‐doped nickel hydroxide scaffold that anchors iridium as isolated single atoms (SAs) using a phytate ligand. The hierarchical nanoarray catalyst efficiently drives simultaneous hydrogen and oxygen evolution in alkaline media, enabling industrial‐level current densities and long‐term stability in an anion‐exchange‐membrane ...

New Insights into the Genetic Mechanism of the Miocene Mounded Stratigraphy in the Qiongdongnan Basin, Northern South China Sea

Energies, 2022
The origin of deep-water mounds has been a topic of debate in recent years. In this study, newly collected seismic data were employed to characterize the mounds within the Meishan Formation in the Qiongdongnan Basin and a novel model was proposed.

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

The Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)

The Anatomical Record, EarlyView.
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

The Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...
