Advances in Halide Perovskites for Photon Radiation Detectors

open access: yesAdvanced Materials Technologies, EarlyView.
This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Statistical studies of random lasing modes and amplified spontaneous emission spikes in weakly scattering systems

open access: yes, 2007
We measured the ensemble-averaged spectral correlation functions and statistical distributions of spectral spacing and intensity for lasing modes in weakly scattering systems, and compared them to those of the amplified spontaneous emission spikes. Their

A High‐Throughput AngioPlate Platform with Integrated AngioTEER for Modeling and Monitoring Renal Proximal Tubule Injury

open access: yesAdvanced Materials Technologies, EarlyView.
Renal tubular injury is a major contributor to kidney disease, yet remains poorly understood due to the lack of predictive models. This study presents a high‐throughput 3D renal proximal tubule model on the AngioPlate platform integrated with automated TEER measurements (AngioTEER), enabling real‐time monitoring of drug‐induced nephrotoxicity ...

Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.

Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles

open access: yesAdvanced Optical Materials, EarlyView.
Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.

Modelling the performance of fluorescent solar collectors

open access: yes, 2011
The theoretical power conversion efficiency of a silicon solar cell with a fluorescent solar collector is believed to reach 90% of the maximum efficiency of an ideal silicon solar given by the Shockley-Queisser detailed balance limit, but the practical ...

Mechanisms of Glomerular Albumin Filtration and Tubular Reabsorption

open access: yesInternational Journal of Nephrology, 2012
Albumin is filtered through the glomerulus with a sieving coefficient of 0.00062, which results in approximately 3.3 g of albumin filtered daily in human kidneys.
