Ab initio study of element segregation and oxygen adsorption on PtPd and CoCr binary alloy surfaces

open access: yes, 2008
The segregation behavior of the bimetallic alloys PtPd and CoCr in the case of bare surfaces and in the presence of an oxygen ad-layer has been studied by means of first-principles modeling based on density-functional theory (DFT).

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

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

open access: yesAdvanced 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 ...

Enhancing machine learning-based seismic facies classification through attribute selection: application to 3D seismic data from the Malay and Sabah Basins, offshore Malaysia

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Over the past few years, the use of machine learning has gained considerable momentum in many industries, including exploration seismic. While supervised machine learning is increasingly being used in seismic data analysis, some obstacles hinder its ...

Probing the Cause of Capacity Fade in Large‐Format Li‐Ion Pouch Cells through Multimodal Characterization

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A comprehensive multimodal characterization of two end‐of‐life cells from a retired Nissan Leaf battery pack, subjected to accelerated aging to mimic extended use in second‐life applications shows that electrolyte degradation and loss is a more critical contributor to cell degradation toward the knee‐point in these cells than degradation of the ...
