A Crystallographic Shear Driven by Oxygen Insertion in (LuFeO3)nLuFe2O4

open access: yesChemistryEurope, EarlyView.
Layered structures (LuFeO3)nLuFe2O4 exhibit a common structural transformation upon oxygen uptake. Although the LuFeO3 units do not directly participate in oxygen insertion, these inactive layers nevertheless influence the temperature at which oxygen absorption occurs.

Synthetic aperture rainbow refractometry

Optics Letters, 2022
This work proposed a synthetic aperture rainbow refractometry (SARR) by synthesizing rainbow signals of the same droplet with dual-wavelength laser beams, in order to increase the aperture of rainbow refractometry. In this way, the SARR can apply to long distance and small droplets measurement. An achromatic imaging system, which simultaneously records

Synthetic aperture ultrasound imaging

Ultrasonics, 2006
The paper describes the use of synthetic aperture (SA) imaging in medical ultrasound. SA imaging is a radical break with today's commercial systems, where the image is acquired sequentially one image line at a time. This puts a strict limit on the frame rate and the possibility of acquiring a sufficient amount of data for high precision flow estimation.
