The price of dialysis access: Implications of access type and patient-centric approaches to cost.

Purpose: This study explores out-of-pocket (OOP) costs for patients and provider reimbursement for dialysis access creation. It aims to illustrate the financial characteristics of four dialysis access modalities to consider in decision-making for clinicians, patients, and payers.

Materials And Methods: Retrospective data from the Merative™ MarketScan Commercial Claims and Encounters Databases from 2017 to 2022 was analyzed for patients who received an arteriovenous fistula (AVF), arteriovenous graft (AVG), peritoneal dialysis catheter (PDC), or percutaneous AVF (pAVF).

Enhancing SiGeSn nanocrystals SWIR photosensing by high passivation in nanocrystalline HfO matrix.

SiGeSn nanocrystals (NCs) in oxides are of considerable interest for photo-effect applications due to the fine-tuning of the optical bandgap by quantum confinement in NCs. We present a detailed study regarding the silicon germanium tin (SiGeSn) NCs embedded in a nanocrystalline hafnium oxide (HfO) matrix fabricated by using magnetron co-sputtering deposition at room temperature and rapid thermal annealing (RTA). The NCs were formed at temperatures in the range of 500-800 °C.

Lead-Free Perovskite Thin Films with Tailored Pockels-Kerr Effects for Photonics.

Pockels and Kerr effects are linear and nonlinear electro-optical effects, respectively, used in many applications. The modulation of the refractive index is employed in different photonic circuits. However, the greatest challenge is in photonic elements for quantum computing at room temperature.

Titania nanoparticles for photocatalytic degradation of ethanol under simulated solar light.

TiO nanoparticles were synthesized by laser pyrolysis from TiCl vapor in air in the presence of ethylene as sensitizer at different working pressures (250-850 mbar) with and without further calcination at 450 °C. The obtained powders were analyzed by energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray diffractometry, and transmission electron microscopy. Also, specific surface area and photoluminescence with optical absorbance were evaluated.

Ferroelectric Orthorhombic ZrO Thin Films Achieved Through Nanosecond Laser Annealing.

A new approach for the stabilization of the ferroelectric orthorhombic ZrO films is demonstrated through nanosecond laser annealing (NLA) of as-deposited Si/SiO /W(14 nm)/ZrO (8 nm)/W(22 nm), grown by ion beam sputtering at low temperatures. The NLA process optimization is guided by COMSOL multiphysics simulations. The films annealed under the optimized conditions reveal the presence of the orthorhombic phase, as confirmed by X-ray diffraction, electron backscatter diffraction, and transmission electron microscopy.
