Overview: Computer vision and machine learning for microstructural characterization and analysis [PDF]

open access: yes, 2020
The characterization and analysis of microstructure is the foundation of microstructural science, connecting the materials structure to its composition, process history, and properties. Microstructural quantification traditionally involves a human deciding a priori what to measure and then devising a purpose-built method for doing so.

The Microstructure of Isichazamazwi SesiNdebele

open access: yesLexikos, 2009
This article analyses the microstructure of Isichazamazwi SesiNdebele. The analysis takes place on two levels: the level of availability of information and the level of accessibility of the available information to dictionary users. Data derived from two outreach exercises carried out to ascertain users' perspectives on the dictionary and their ...

Detection of polarized quasi-periodic microstructure emission in millisecond pulsars [PDF]

open access: yes, 2016
Microstructure emission, involving short time scale, often quasi-periodic, intensity fluctuations in subpulse emission, is well known in normal period pulsars. In this letter, we present the first detections of quasi-periodic microstructure emission from

Impact of microstructure on local carrier lifetime in perovskite solar cells

open access: yesScience, 2015
Going toward the grains Great strides have been made in improving the efficiency of organic-inorganic perovskite solar cells. Further improvements are likely to depend on understanding the role of film morphology on charge-carrier dynamics.

Nano-CT characterization of dentinal tubule occlusion in SDF-treated dentin

open access: yesScientific Reports, 2023
Dentin hypersensitivity is an oral health concern affecting a large percentage of the world's adult population. Occlusion of the exposed dentinal tubules is among the treatment options available, and silver diammine fluoride (SDF) is an occluding agent ...

Elliptical Bloch skyrmion chiral twins in an antiskyrmion system

open access: yesNature Communications, 2020
Skyrmions and anti-skyrmions often exist in distinct material systems. Here, the authors observe elliptical skyrmions and anti-skyrmions with opposite topological charges in one tetragonal Heusler compound Mn1.4Pt0.9Pd0.1Sn with D 2d symmetry.

Direct Observation of the Deformation Mechanism of Twin-Structured Ni NWs under Bending Strain

open access: yesMetals, 2022
In situ atomic-scale bending tests of twin-structured Ni nanowires were realised using a homemade deformation device. The results showed that the plastic deformation mechanism in twin-structured Ni nanowires depended on the deformation stage.

Optical coherence tomography for the non-invasive investigation of the microstructure of ancient Egyptian faience [PDF]

open access: yes, 2012
Optical Coherence Tomography (OCT) is a non-invasive subsurface 3D imaging technique based on the Michelson interferometer. The non-invasive nature of OCT and its speed of acquisition makes it possible to image large volumes of intact objects to yield a ...

Switching of spins and entanglement in surface-supported antiferromagnetic chains

open access: yesScientific Reports, 2017
Previous experimental studies discovered universal growth of chains and nanowires of various chemical elements on a corrugated molecular network of Cu3N on the Cu(110).
