Optical pumping in dense atomic media: Limitations due to reabsorption of spontaneously emitted photons [PDF]

open access: yes, 1998
Resonant optical pumping in dense atomic media is discussed, where the absorption length is less than the smallest characteristic dimension of the sample.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

3D Multicellular Scaffold Based Model for Advancing Bone Disorder Research

open access: yesAdvanced Functional Materials, EarlyView.
A scalable 3D multicellular in vitro bone model engineered by integrating osteoblasts, osteoclasts, and endothelial cells on biodegradable scaffolds. The system recapitulates key features of human bone remodeling and disease pathology. As a proof of concept, the model mimics osteogenesis imperfecta, demonstrating its potential as a physiologically ...

Hybrid remote quantum dot/powder phosphor designs for display backlights [PDF]

open access: yes, 2017
Quantum dots are ideally suited for color conversion in light emitting diodes owing to their spectral tunability, high conversion efficiency and narrow emission bands.

Mechanically Tunable Bone Scaffolds: In Vivo Hardening of 3D‐Printed Calcium Phosphate/Polycaprolactone Inks

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

SODIUM REABSORPTION ESTIMATION FOR EVALUATION OF FUNCTIONAL STATE OF TRANSPLANTED KIDNEY

open access: yesВестник трансплантологии и искусственных органов, 2009
Sodium reabsorption and sodium consumption (daily sodium excretion) were studied in 63 health volunteers and 100 recipients of kidney allografts. We elaborated the nomogramm for definition of sodium reabsorption with confidence interval 95% and proposed ...

Novel Mechanistic PBPK Model to Predict Renal Clearance in Varying Stages of CKD by Incorporating Tubular Adaptation and Dynamic Passive Reabsorption

open access: yesCPT: Pharmacometrics & Systems Pharmacology, 2020
Chronic kidney disease (CKD) has significant effects on renal clearance (CLr) of drugs. Physiologically‐based pharmacokinetic (PBPK) models have been used to predict CKD effects on transporter‐mediated renal active secretion and CLr for hydrophilic ...

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
