Strategies for Controlling Emission Anisotropy in Lead Halide Perovskite Emitters for LED Outcoupling Enhancement

Advanced Materials, EarlyView.
The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

FFT-Based Frequency Detection and Interference Analysis for NLOS MIMO-OCC

IEEE Access
In this paper, we provide a solution based on fast Fourier Transform (FFT) for frequency detection and interference analysis in a non-line-of-sight (NLOS) multiple-input multiple-output (MIMO) optical camera communications (OCC) link.

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

Advanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Analytical investigations on the Maxwell electromagnetic invariant in the spinning and charged horizonless star background [PDF]

arXiv
We study properties of the Maxwell electromagnetic invariant in the external region of spinning and charged horizonless stars. We analytically find that the minimum negative value of the Maxwell electromagnetic invariant is obtained on the equator of the star surface.
