Geoscientists’ Perspectives on Cyberinfrastructure Needs: A Collection of User Scenarios

open access: yesData Science Journal, 2019
Cyberinfrastructure (CI) is a standard tool in the geosciences, but the creation of successful CI remains difficult, and expensive projects can have significant consequences for scientific communities if they do not result in success.

A Thirty‐Year Gap: Reviving All‐Nitride Glasses as Processable, High‐Performance Materials

open access: yesAdvanced Science, EarlyView.
Oxygen‐free all‐nitride glasses are revisited in light of new avenues of synthesis, raw material availability, and applications. A semi‐empirical analysis predicts mechanical performance achieving the level of engineering ceramics while maintaining visual transparency, and significant potential regarding optical properties into the infrared spectral ...

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

open access: yesAdvanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...

Surface‐Strained NiMo Cathodes Enable Kinetics‐Decoupled Hydrogen Bubble Management for Stable Near‐Neutral Water Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
Surface strain tunes the NiMo/electrolyte interface without altering intrinsic hydrogen evolution reaction (HER) kinetics. The strained surface exhibits a lower effective bubble‐detachment tendency and faster release of smaller H2 bubbles, sustaining a more accessible catalytic interface in near‐neutral electrolyte. Reduced bubble‐induced transport and

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,

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.
