Recent advances in atomic resolution three-dimensional holography

open access: yesAdvances in Physics: X
Three-dimensional (3D) local atomic structure around specific functional atom plays a crucial role in functional materials, but it has not been able to be analyzed by a standard structure analysis method of x-ray diffraction (XRD) because this kind of ...

Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

open access: yesSmall, EarlyView.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

Holography in Sweden 2000

open access: yes, 2000
Looking back on the earlier reports on Holography in Sweden, it is striking that not much has changed during the last decade. It is more or less the same people that have been active throughout this period. It is difficult to say if holography is loosing

The contribution by Nils Abramson to the field of holography

open access: yes, 2023
Nils Abramson (1931 - 2019) was one of the true pioneers of holography. Shortly after lasers were made available in the1960s, he started research on how they could be used in engineering.

Imaging Ionic Displacements Across Inclined Ferroelectric Domains by a Reciprocity Approach to 4D‐STEM

open access: yesSmall, EarlyView.
Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM

Vortex Domain Wall Imaging in a 3D Magnetic Nanotube Grown by Focused Electron Beam Induced Deposition

open access: yesSmall, EarlyView.
Synthesis of nanoscale high‐purity Co magnetic nanotubes using a single growth technique, focused electron beam induced deposition (FEBID). Utilizing electron holography and micromagnetic simulations, we demonstrate the nucleation and pinning of tilted vortex domain walls, providing crucial experimental evidence to advance 3D spintronics and ...

Holography, relativity and the spooky ellipsoids

open access: yes, 2006
The further away from a house we move, the smaller it appears. We could say that we are in the centre of a "sphere of observation", which must reach the house before we can see it. The larger that sphere is, the smaller the house appears. This is natural

Multi‐Wavelength Achromatic 3D Meta‐holography with Zoom Function

open access: yesAdvanced Science
With the development of nanofabrication technology, meta‐holography has shown unprecedented potential for light regulation. However, due to the wavelength mismatch, chromatic aberrations are inevitable in multi‐wavelength meta‐holography. Moreover, since

Improving ARTs: Microfluidics as a Tool for Sperm Selection

open access: yesAndrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.
