Spin Dynamics of Excitons and Carriers in Mixed‐Cation MAxFA1–xPbI3 Perovskite Crystals: Alloy Fluctuations Probed by Optical Orientation

Advanced Physics Research, EarlyView.
The impact of alloy fluctuations on the spin dynamics of mixed‐cation MAxFA1‐xPbI3 perovskite single crystals is studied experimentally by means of polarized time‐resolved photoluminescence. The high optical orientation degree, reaching 80% for x = 0.1 and 0.8, displays a minimum of 60% for x = 0.4.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Force stimulation promotes nerve regeneration by restoring cellular energy

BMEMat, EarlyView.
Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...
