The Effect of Formulated Dentin Remineralizing Gel Containing Hydroxyapatite, Fluoride, and Bioactive Glass on Dentin Microhardness: An In Vitro Study. [PDF]

Int J Dent
Objectives. This study aimed to develop a gel with dentin‐remineralizing properties, integrating nano‐hydroxyapatite (nHA), sodium fluoride (NaF), and bioactive glass (BG). Materials and Methods. The enamel layer of 40 bovine incisors was removed. The samples were allocated into four groups of 10 each, based on varying concentrations of nHA, BG, and ...

Mesoporous Bioactive Glass Nanoparticles in the SiO₂-P₂O₅-CaO-MO (M=Mg, Zn) System: Synthesis and Properties

Journal of Functional Biomaterials, 2022
Mesoporous bioactive glass nanoparticles (MBGNs) are widely recognized for their ability to bond to hard tissue, while the ions released from the BG structure enhance specific cellular pathways. In this study, the SiO2-P2O5-CaO-MgO-ZnO system was used to

Muon spin relaxation study of phosphosilicate gels

Solid State Ionics, 2020
Abstract Muon dynamics in phosphosilicate proton conductors P2O5-SiO2 with a composition 30 mol% phosphorus oxide (30P) have been studied as a function of temperature using muon spin relaxation. For materials heat treated at 300 °C the muons implant at sites close to P-OH groups associated with water molecules.

Electrochemical Ionic Synapses: Progress and Perspectives

Advanced Materials, Volume 35, Issue 37, September 14, 2023., 2023
Electrochemical ionic synapses (EISs) are programmable resistors whose conductivity is controlled deterministically by electrochemical charge insertion. Their repeatable conductance modulation and low energy consumption render them promising for enabling analog deep learning architectures with uncompromised accuracy and superior energy efficiency. Here,

3D bioprinting microgels to construct implantable vascular tissue

Cell Proliferation, Volume 56, Issue 5, May 2023., 2023
The synergy of strength and biocompatibility in one matrix is essential to meet angiogenic HUVEC‐based sprouting and bear shear stress for implanting tissue engineering for clinical applications at a large scale. Here, the authors demonstrate a design strategy of microgel reinforced cell‐laden matrix with heterogeneous stiffness for constructing ...

Structure and properties of cerium phosphate and silicophosphate glasses

Journal of the American Ceramic Society, Volume 106, Issue 5, Page 2808-2819, May 2023., 2023
Abstract We report on the fabrication, properties, and structure of cerium pyrophosphate glasses and partially substituted cerium silicophosphates. In those glasses, cerium occurs predominantly as Ce(III). A combination of dynamic nuclear magnetic resonance and electrical impedance spectroscopy is used to overcome the problem of assessing cerium ...
