Unravelling the Spatiotemporal Exciton Dynamics in Electrically Pumped Organic Laser Diodes

Laser &Photonics Reviews, EarlyView.
High‐speed OLED measurements combined with advanced simulations reveal how singlet, triplet, and polaron dynamics drive key loss channels that hinder organic semiconductor lasing, while presenting strategies to overcome them. Abstract Organic materials offer wide‐band emission covering regions of the spectrum unachievable by conventional semiconductors.

General‐Purpose Hexagonal Programmable Photonic Integrated Circuit with a >30 GHz Free Spectral Range

Laser &Photonics Reviews, EarlyView.
A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Bilateral Transcranial Doppler Monitoring During Neonatal Cardiac Surgery; Guidance for Clinical and Scientific Use

Pediatric Anesthesia, EarlyView.
ABSTRACT Introduction Neonates undergoing cardiac surgery face a high risk of neurological injury and neurodevelopmental complications. Transcranial Doppler monitoring is used and validated in adults to measure cerebral blood flow and can provide valuable insights into cerebral perfusion in neonates.

The Sooner, the Better: Neuroprotective Strategies in Fetuses With Congenital Heart Disease

Prenatal Diagnosis, EarlyView.
ABSTRACT Congenital heart disease (CHD) is the most frequent congenital malformation at birth and is associated with neurodevelopmental impairments. Alterations in cardiovascular physiology can lead to reduced cerebral blood perfusion and oxygenation, which negatively affects brain growth and maturation.

On the Electron Transport in Simplified IBC‐SHJ Solar Cells With MoOx Blanket Layer

Progress in Photovoltaics: Research and Applications, EarlyView.
In this work, we present a study of electron transport through a novel (n)nc‐Si:H/MoOx stack to improve the understanding and performance of simplified IBC‐SHJ solar cells with MoOx blanket layer. The champion solar cell fabricated with the optimized contact stack and metalized with copper electroplating enables efficiencies beyond 23.5%.

No increased risk of spinal cerebrospinal fluid leak after spinal manipulative therapy: A retrospective cohort study

PM&R, EarlyView.
Abstract Background Spinal cerebrospinal fluid (CSF) leaks, a rare but debilitating condition, have been described following spinal manipulative therapy (SMT) in case reports. However, the nature of the potential association between SMT and CSF leak is uncertain, and symptoms such as neck pain or headache may reflect preexisting leaks rather than ...

Multifrequency Multiparameter Magnetic Resonance Elastography Applied to an In Vivo Porcine Model for Assessing Portal Hypertension

Portal Hypertension &Cirrhosis, EarlyView.
Portal hypertension, a critical complication in chronic liver disease, has long relied on invasive hepatic venous pressure gradient measurement for definitive diagnosis. This study establishes that multifrequency three‐dimensional magnetic resonance elastography (3D‐MRE) can noninvasively quantify portal pressure, with splenic stiffness and loss ...

Tunable Josephson Generator for Qubit Excitation and Two‐Tone Spectroscopy

Advanced Quantum Technologies, EarlyView.
A tunable on‐chip Josephson generator that enables direct qubit excitation has been presented. The device consists of a current‐biased Josephson junction and a superconducting resonator, forming a microwave source that operates at 4 K. Excitation of the qubit at 20 mK was done via a short coaxial line between the 4 K and 20 mK stages.

Strategic Spatial Segregation in Silicon Photoelectrodes: Decoupling Catalytic and Optical Functions for High‐Efficiency Solar Water Splitting

Small Structures, Volume 6, Issue 5, May 2025.
A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...
