Insights into the Chemical Durability and Structure of ZnO-Incorporated Sodium Borosilicate Glasses from Solid-State NMR.

ZnO-incorporated NBS glasses have been studied for their application as a matrix for nuclear waste immobilization. However, structural factors affecting chemical durability have not been established. In this study, the structural changes in NBSZn glasses across various NaO/(BO + ZnO) ratios are explored using multinuclear MAS, MQMAS NMR, and EXAFS techniques.

Mechanochemical Large-Scale Rapid Synthesis of Ultrapure Sodium Hexafluorophosphate.

Among the sodium battery electrolytes, sodium hexafluorophosphate (NaPF) exhibits superior conductivity, anodic stability, and stable cathode electrolyte interface compared to other electrolytes. Therefore, the synthesis of pure NaPF through a simple process is very important. Usually, NaPF is synthesized using HF.

Practice Patterns of Reirradiation for Brain and Spinal Tumors-An International Survey From the Reirradiation Collaborative Group (ReCOG).

Purpose: An international workshop was convened by the Reirradiation Collaborative Group. We conducted a survey among the invited attendants to assess practice patterns of reirradiation for central nervous system tumors.

Methods And Materials: A web-based survey regarding central nervous system reirradiation was distributed to an international group of radiation oncologists and medical physicists via email.

Extraction of highly crystalline and thermally stable cellulose nanofiber from Heliconia psittacorum L.f. leaves.

Extracting cellulose nanofibers (CNF) from agro-waste is one of the promising and practical ways to develop sustainable nanocomposites. In this study, cellulose nanofibers were extracted from the leaves of Heliconia psittacorum for the first time. The combination of oxalic acid hydrolysis (5 wt%) and steam explosion was used for the isolation of CNF from the leaves of Heliconia psittacorum.

Probing the Effect of Fluorine on Hydrogen Bonding Interactions in a Pharmaceutical Hydrate Using Advanced Solid-State NMR.

Structural studies of pharmaceutical hydrates are essential to understanding stability-related issues, especially during the heating process of formulation. A thorough understanding of the hydration and dehydration behavior of active pharmaceutical ingredient (API) hydrate is also important since phase transitions can occur during the formulation process. This is because dehydration could result in a considerable rearrangement in the structure if water-API hydrogen bonding is present.
