Exploring the Phase-Selective, Green, Hydrothermal Synthesis of Upconverting Doped Sodium Yttrium Fluoride: Effects of Temperature, Time, and Precursors. | LitMetric
The aim of this work was i) to develop a hydrothermal, low-temperature synthesis protocol affording the upconverting hexagonal phase NaYF with suitable dopants while adhering to the "green chemistry" standards and ii) to explore the effect that different parameters have on the products. In optimizing the synthesis protocol, short reaction times and low temperatures (below 150 °C) were considered. Yb and Er ions were chosen as dopants for the NaYF material. Within the context of the second goal, parameters including nature of the precursors, treatment temperature, and treatment time were investigated to afford a pure hexagonal crystalline phase, both in the doped and undoped materials. To fully explore the synthesis results, the prepared materials were characterized from a structural (XRD), compositional (XPS, ICP-MS), and morphological (SEM) point of view. The upconverting properties of the compounds were confirmed by photoluminescence measurements.
Background And Objective: Dental implant therapy faces challenges in patients with Type 1 and Type 2 Diabetes Mellitus (T1DM and T2DM) due to adverse effects on bone metabolism and immune response. Despite advancements, diabetic patients face higher risks of peri-implantitis and compromised osseointegration. This review assesses the impact of anti-diabetic medications on implant outcomes, offering insights to bridge the gap between animal studies and clinical practice.

An unprecedented Pd-catalyzed cascade alkyne insertion/Heck/C-H activation reaction of -iodophenyl alkenyl ethers and diarylacetylenes has been developed. Diversified tetracyclic-fused dihydroindeno[2,1-]chromenes bearing a quaternary center were constructed in an efficient, straightforward, and atom-economic way with good to excellent yields. The protocol features high bonding efficiency, operational simplicity, broad substrate scope, and easy scale-up.
Background: Preeclampsia (PE) is a serious pregnancy complication associated with impaired trophoblast function. Integrin β3 (ITGB3) is a cell adhesion molecule that plays a role in cell movement. The objective of this study was to identify the biological function and expression level of ITGB3 in PE.
Introduction: Ovarian cancer remains a leading cause of mortality among gynecological malignancies, often diagnosed at advanced stages due to nonspecific symptoms and limited screening tools. Standard treatment, including cytoreductive surgery and chemotherapy, can cause fatigue, physical dysfunction, and psychological distress, impacting quality of life. Exercise interventions have shown potential to mitigate these effects, but inconsistent methodologies in randomized controlled trials (RCTs) limit reliable conclusions and clinical integration.
Background: Surrogate decision-makers play a key role in determining whether end-of-life patients receive hospice care. There is a need to better understand families' experiences of surrogate decision-making in hospice care for end-of-life patients to provide a basis for developing targeted interventions, such as decision support tools or counseling, to help family members navigate the decision-making process.
Aim: The aim was to analyze and synthesize global qualitative data on family members' experiences of surrogate decision-making regarding whether to receive hospice care for end-of-life patients.
