Strong flows of dilute suspensions of microstructure [PDF]

, 1991
We consider dilute suspensions that have a microstructure that may be characterized by an axial state vector. Examples include axisymmetric particles, line elements of the fluid itself, or, as an approximation, droplets of fluid or polymer molecules ...

Elliptical Bloch skyrmion chiral twins in an antiskyrmion system

Nature 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.

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

, 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 ...

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

, 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

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

Metals, 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.

Digital fingerprinting of microstructures

Computational Materials Science, 2023
Finding efficient means of fingerprinting microstructural information is a critical step towards harnessing data-centric machine learning approaches. A statistical framework is systematically developed for compressed characterisation of a population of images, which includes some classical computer vision methods as special cases.

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

Scientific 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 ...
