Controlled Formation of Nanoribbons and Their Heterostructures via Assembly of Mass-Selected Inorganic Ions
Control of nanomaterial dimensions with atomic precision through synthetic methods is essential to understanding and engineering of nanomaterials. For single-layer inorganic materials, size and shape controls have been achieved by self-assembly and surface ...
Weinheim2024Evaluation of Interface and Residual Strain of NiTi Layer Deposited on NiTiX Substrate by Laser Powder Bed Fusion
Christian Leinenbach, Elyas Ghafoori, Irene Ferretto, Mahbod Golrang, Mahshid Memarian
This study investigates the microstructure and properties of functionally graded NiTi alloy bilayers. The NiTi layer is printed by laser powder bed fusion on a NiTiX (where X is Hf or Cu) substrate prepared by vacuum arc remelting. Specimens produced with ...
Wiley-V C H Verlag Gmbh2024Non-negative matrix factorization-aided phase unmixing and trace element quantification of STEM-EDXS data
Cécile Hébert, Duncan Thomas Lindsay Alexander, James Badro, Farhang Nabiei, Hui Chen
Energy-dispersive X-ray spectroscopy (EDXS) mapping with a scanning transmission electron microscope (STEM) is commonly used for chemical characterization of materials. However, STEM-EDXS quantification becomes challenging when the phases constituting the ...
Elsevier2024Optimizing Atomic Layer Deposition Processes with Nanowire-Assisted TEM Analysis
Johann Michler, Ivo Utke, Xavier Maeder
Atomic layer deposition (ALD) is one of the premier methods to synthesize ultra-thin materials on complex surfaces. The technique allows for precise control of the thickness down to single atomic layers, while at the same time providing uniform coverage ev ...
Hoboken2024Quasi-operando Transmission Electron Microscopy Diagnostics for Electrocatalytic Processes in Liquids
It is of great interest to the energy community to understand how the mechano-physico-chemical phenomena that eventually lead to device degradation are related to the startup, operation, and shutdown phases. For electrocatalytic systems operating in liquid ...
Swiss Chemical Soc2024Mapping orthorhombic domains with geometrical phase analysis in rare-earth nickelate heterostructures
Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone
Most perovskite oxides belong to the Pbnm space group, composed of an anisotropic unit cell, A-site antipolar displacements, and oxygen octahedral tilts. Mapping the orientation of the orthorhombic unit cell in epitaxial heterostructures that consist of at ...
Melville2024Molecular mechanism of plasmid elimination by the DdmDE defense system
Melanie Blokesch, Sandrine Stutzmann, David William Adams, Laurie Righi
Seventh pandemic Vibrio cholerae strains contain two pathogenicity islands that encode the DNA defense modules DdmABC and DdmDE. Here we use cryogenic electron microscopy to reveal the mechanistic basis for plasmid defense by DdmDE. A structure of the DdmD ...
2024Solution-based Cu+ transient species mediate the reconstruction of copper electrocatalysts for CO2 reduction
Raffaella Buonsanti, Anna Loiudice, Petru Pasquale Albertini, Jan Vávra, Gaétan Philippe Louis Ramona
Understanding metal surface reconstruction is of the utmost importance in electrocatalysis, as this phenomenon directly affects the nature of available active sites. However, its dynamic nature renders surface reconstruction notoriously difficult to study. ...
Berlin2024Microstructure - Electrochemical Surface Reactivity Relationship of Electrochemically Grown Manganese Oxides Films
This Thesis provides a comprehensive and correlative investigation of the microstructure, chemical state, and electrochemical reactivity of manganese oxide (MnOx) films, aiming to gain a deeper understanding of the deposition and dissolution mechanism of M ...
EPFL2024Exciton migration in two-dimensional materials
Excitons play an essential role in the optical response of two-dimensional materials. These are bound states showing up in the band gaps of many-body systems and are conceived as quasiparticles formed by an electron and a hole. By performing real-time simu ...
