Abstract

Rare earth sulfides are environmentally friendly and have excellent physical optoelectronic properties and coloring applications. In particular, red γ-Ce2S3 is an important and popular inorganic optical functional material. However, it has become crucial to improve the production efficiency of γ-Ce2S3 and its color performance and stability. By adding ammonium thiocyanate to the precursor, eco-friendly γ-Ce2S3 with excellent color performance was produced in this study. In addition, the effect of different amounts of Na+ doping on the final product's purity and the effect of chroma value were systematically investigated. Results show that an increase in Na+ can effectively lower the synthesis temperature of γ-Ce2S3, improve production efficiency, and optimize color performance prior to saturation. Finally, using density functional theory, the influence of the vacancy structure of γ-Ce2S3 and the change of energy band after the addition of Na+ were calculated, and a detailed experimental characterization in conjunction with density functional theory calculation thoroughly explained the significance of ion doping for reaction synthesis.

Abstract

Light-emitting diodes (LEDs) combined with near-infrared (NIR) phosphors are rapidly becoming important light sources for food safety, anti-counterfeiting and biological imaging due to non-destructive and non-toxic advantages. Single-phase materials with multi-mode luminescence under different stimuli are crucial for the development and applications of smart NIR phosphors. Here, we have developed multifunctional Cr3+ activated MgGa2O4 (MGO:Cr3+) phosphors with simultaneous photoluminescence and mechanoluminescence for NIR sensing. Under 470 nm excitation, the phosphors can produce emission bands from 650 to 850 nm. Meanwhile, the flexible devices based on phosphors can exhibit strong emissions in response to mechanical deformation, such as shock and friction. In addition, optical manometers based on luminescence from phosphors can achieve pressure sensing from 7 to 64 KPa. More intriguingly, we combined the MGO:Cr3+ phosphor with a blue LED chip to fabricate an NIR phosphor-converted LED for anti-counterfeiting and biological tissue penetration. Our results suggest that the multifunctional NIR phosphors with simultaneous photoluminescence and mechanoluminescence have potential applications in various sensing devices. [ABSTRACT FROM AUTHOR]

Abstract

Isavuconazole (ISA) is a second generation broad-spectrum triazole antifungal drug derived from voriconazole structure, and its oral capsules is currently the only oral preparation approved for invasive mucormycosis. In recent years, population pharmacokinetic studies of ISA have been reported continuously. This paper aims to summarize the characteristics of population pharmacokinetic models of ISA in adults, and provide theoretical basis for individualized administration of ISA. We systematically searched PubMed, Embase, CNKI, Wanfang, VIP and other databases to collect population pharmacokinetic models published from the establishment of the database to March 2023. A total of 6 studies were included in this review, including healthy men and women, invasive fungal infections with malignant tumors or neutropenia, solid organ transplantation. The dose of ISA was 40– 400mg for single-dose. The multiple-dose of ISA was 200mg every 8 hours for the first 48 hours and then 200mg once daily. All studies used a two-compartment model, first-order elimination. For oral formulations, except for one study that used first-order absorption, the others used Weibull absorption. Body mass index (BMI) was the most common covariable, followed by total body weight, lean body mass, race, sex, population type (healthy volunteers/patients), and creatinine clearance. These studies included several covariates, and the clearance rate (CL) was similar among populations. In the future, external validation and population pharmacokinetic studies in special populations such as patients with severe liver disease and ECMO support are needed. [ABSTRACT FROM AUTHOR]
