Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Evidence of new twinning modes in magnesium questioning the shear paradigm

, 2017
Twinning is an important deformation mode of hexagonal close-packed metals. The crystallographic theory is based on the 150-years old concept of simple shear. The habit plane of the twin is the shear plane, it is invariant.

Assessment of crystallographic influence on material properties of calcite brachiopods [PDF]

, 2008
Calcium carbonate biominerals are frequently analysed in materials science due to their abundance, diversity and unique material properties. Aragonite nacre is intensively studied, but less information is available about the material properties of ...

Automated 3D EBSD for metallic powders

MethodsX, 2018
Metallic powders are commonly used in additive manufacturing processes. While their post-process consolidated properties are widely studied, there is little research on the properties of the powders prior to consolidation. Understanding the powder characteristics before use in additive manufacturing processes could lead to fine-tuning properties of ...

Non‐Destructive Laser Nanopatterning of Superconducting Heterostructures in Topological Sn Thin Films

Advanced Materials, EarlyView.
We demonstrate successful fabrication of high‐quality α‐Sn/β‐Sn planar nanostructures with arbitrary shapes by focused laser irradiation on topological Dirac semimetal α‐Sn thin films. The irradiated regions transform into atomically smooth, superconducting β‐Sn with a critical temperature of 3.7 K.

Electron imaging with an EBSD detector

Ultramicroscopy, 2015
Electron Backscatter Diffraction (EBSD) has proven to be a useful tool for characterizing the crystallographic orientation aspects of microstructures at length scales ranging from tens of nanometers to millimeters in the scanning electron microscope (SEM).

Loading Mode Dependence of Twin‐Twin Boundary Formation in a Textured Magnesium Alloy

Advanced Materials Interfaces, EarlyView.
The structures of twin‐twin boundaries formed by interactions between twin variants sharing the same or different zone axes in a deformed magnesium alloy are demonstrated. Lattice distortion around complicated interfaces promotes grain refinement in the subsequent thermomechanical process, enhancing the mechanical performance of magnesium alloys ...

Estudio de la solidificación de recubrimientos de acero rápido M2 obtenidos por Laser Cladding

Revista de Metalurgia, 2013
Los recubrimientos de acero rápido por Laser Cladding (LC) son complejos porque aparecen fisuras y la dureza es menor a la esperada. En este trabajo se han fabricado recubrimientos de acero AISI M2 sobre acero al carbono AISI 1045 y tras el procesado por

TEM study of the effect of high-temperature thermal cycles on the stability of the Y-Al-O oxides in MA956 ODS steel [PDF]

, 2019
MA956, a commercial ferritic grade of Oxide Dispersion-Strengthened (ODS) steel, was investigated using transmission electron microscopy (TEM) to evaluate the influence of high-temperature thermal cycles on the nanometric dispersed oxides.

Multimodal Imaging of Strain and Light Emission of Core–Shell InGaN/GaN Wires under a Sub‐Micrometer Polychromatic X‐Ray Probe

Advanced Materials Interfaces, EarlyView.
Micro‐Laue diffraction and excited optical X‐ray luminescence are used to study InGaN/GaN core‐shell wires on the BM32 beamline at the European Synchrotron. Multimodal imaging of X‐ray fluorescence, deviatoric strain tensors and optical emissions is performed using simultaneous mapping.
